 ## The ratified-name registry
 
-The name is the primary handle; the ID is the breadcrumb. **In prose, lead with meaning — write "the
-typing law (MD-11)," never bare "MD-n."** (Generalizes MD-8's own footnote.) *Curation* records each
-entry's standing against the ADR three-part test (hard to reverse · surprising without context · a
-real trade-off — see the working discipline in `AGENTS.md`); *durable* entries become `kind:"decision"`
-specs at the decision-spec fold, under the future spec id reserved here. **Fold trigger re-pointed
-(2026-07-11):** originally "post-Slice-1"; slices 1–5 landed with no fold, and the executable-spec
-format decision (plan 12) will rule on the very authoring carrier decision specs would be written in —
-so the fold now waits for that ruling, and the decision specs are authored once, in the format that
-survives. **Format ruled (2026-07-12, the carrier ruling — MD-18):** the Markdown carrier; the fold
-itself rides with the self-hosting session (plan 16 §7).

-> into `ubiquitous-language.md` §1 — conclusion *and* rationale — and was deleted. **MD-6** (Spec named;

-### MD-1 — The Protocol is an executable, self-validating software-delivery meta-model  [ACCEPTED · gloss refined 2026-07-11 (the plan-12 session): "executable specs alone (BDD) is unremarkable" stands as *positioning*, never as a rejection of executability — the ratified framing is that gen 1's disease was a binding invisible to the type system (dual-source + runtime matching), not executable specs; the executable half returns as a **recovered surface under the meta-model headline** (generated step contracts, the typed example space, the oracle), never a pivot]
-**Decision.** We are building a *typed, executable meta-model of the software-delivery process*: teams author
-delivery intent as **`Spec` instances** — the Protocol's one authored truth-primitive — and author only two
-other non-truth constructs, **`Pack`** and **`anchor`**; the meta-model (code in the repo) deterministically
-checks **conformance and honesty** and derives **one graph**; every other artifact is a **projection**.
-The headline is an **executable, self-validating delivery protocol — not just executable specs.**
-**Two permanent honesty guardrails** (these are what keep it from re-becoming the gating we rejected):
-1. It defines the **conformance contract**, and its checks cover **conformance & honesty**, never
-   **content-quality** (design goodness = human/agent judgment) and never **workflow** (no lifecycle gates —
-   the lifecycle-FSM trap).
-2. We claim **"deterministically validated,"** never **"provably correct."**
-**Why / alternatives rejected.** "Executable specs" alone (BDD) is unremarkable; earlier delivery-process frameworks modeled the process only
-*descriptively*; PM tools (Jira/Linear) have process *state* but no *meta-model*. The executable meta-model plus
-conformance + honesty checks is the differentiator. Hard to reverse (everything builds on it); confirmed by the
-user this session.
-
-### MD-2 — Governing language rubric: adopt the nouns, reject the process state-machine  [ACCEPTED]
-**Decision.** Use the established delivery **noun** for any concept the Protocol shares with the industry; coin/keep a
-distinct word only for a real differentiator (and then it must *name the difference*). Reject process
-**state-machine / lifecycle gating** vocabulary. Every term faces two tests: carries epistemic status where it
-matters (authored vs derived), and is unambiguous to all three readers (typed code/CLI · coding agent · Studio
-user).
-**Why.** The system spans a **commercial** user-facing product (Libar Studio: Desktop/Web/CI-CD) *and* the
-AI-native engine; users must not relearn delivery vocabulary. This **reverses** the prior brief's "not a PM tool /
-don't adopt PM ladder names" stance (see scope note).
-
-### MD-4 — One authored primitive; familiar delivery nouns are named coordinates  [ACCEPTED · refined & partially superseded — see note]
-**Decision.** One **authored** primitive (enrich-in-place; never migrated to another artifact type), positioned by
-**three descriptors**: **category of truth** (`kind`) is a *true subtype* (changes required detail + validation);
-**altitude/size** and **maturity** are *positions*. Familiar nouns are **named coordinates, not separate authored
-types**: Decision Record / Use Case / NFR / Contract / Model = `kind`; Epic / Feature / Story = altitude;
-"Executable Spec" = an example-kind instance with a verifier. They are first-class in the **language and Studio
-surfaces**, never separate authored truth-primitives.
-**Why.** Preserves "one primitive" (the differentiation) while honoring "adopt the nouns" — and avoids the
-combinatorial explosion of a subclass per (category × size × maturity) cell. Names deferred per method.
-**Later (2026-06-06; absorbed from the since-removed MD-6).** The primitive is named **`Spec`**, and the three
-descriptor enums are **locked in `ubiquitous-language.md`** (`kind` = 8 values; `altitude` = `epic → feature →
-story`; `readiness` = `idea → scoped → defined → ready`, `ready` carrying a readiness floor). **Partial reversal
-of the above:** a **bounded-context / domain** and a **`capability`** are **not altitudes** — `epic` is the
-altitude ceiling; both are realized as **`Pack` groupings + a Capability Map projection**. Above-epic (initiative
-/ theme) defers, additive later. `candidate` was dropped from readiness (an FSM-status imprint).
-
-### MD-5 — "Software delivery protocol" adopted for the meta layer and the system name  [ACCEPTED 2026-06-07]
-**Decision.** Name the meta layer a **software delivery protocol** — *"not any kind of protocol, it is software"*
-(executable, a reference implementation that *is* the contract). Adopted at the **"name + meta-model noun"**
-depth: "protocol" is both the **product name** (Libar Software Delivery Protocol; short form "the Protocol") and
-the **noun for the meta-layer** (the meta-model *is* the conformance contract). The npm package is the single
-**`@libar-dev/software-delivery-protocol`**; the CLI is **`sdp`**; the repo is `libar-dev/software-delivery-protocol`.
-**Why.** A *protocol* is a **conformance contract, not a workflow** — precisely what MD-1 guardrail 1 states;
-**more honest than "process,"** which carries the workflow connotation we reject. It distances the tool from
-PM/ticket gating and reads cleanly alongside the commercial Studio. (External review — Gemini 3.1 Pro —
-independently endorsed the framing for these reasons.)
-**Resolved tensions.** "Protocol" can connote comms/wire formats, and "process" is the recognized industry noun
-(MD-2 bias) — both are resolved by a **surgical split, not a blanket swap**: "process" is retained for the modeled
-**software-delivery process** (the activity teams perform), for the rejected **process state-machine**, and for
-**delivery-process execution**; only the meta-layer's own naming ("process meta-model" → "the protocol")
-changed. This unparks the naming pass.
-
-### MD-7 — Honesty-sharpenings from the Codex adversarial pass: liveness, impact coverage, `ready` semantics  [ACCEPTED 2026-06-07]
-**Context.** An adversarial review (Codex) probed three trust signals: (1) `implemented` / `has-verifier` are
-anchor-driven and assert no liveness — dead code or a skipped test can look done; (2) file-level blast-radius can
-silently under-report; (3) `ready` is described as "reviewed" but the model records no review fact.
-**Decision.** Resolve all three as **honesty clarifications consistent with already-settled decisions**, *not* via
-the reviewer's heavier remedies:
-1. **Delivery facts are binding/existence, never liveness.** Define an *enabled verifier* as a **structurally
-   bound, resolvable test anchor** — skip / quarantine / glob-exclusion is CI's concern, *exactly as pass/fail
-   is*; add "not reachable/live" to `implemented`; name the ladder `implemented → has-verifier → observed`, with
-   **`observed`** (aspirational) as the liveness rung. *Rejected: renaming `implemented`→`has-anchor` — it guts
-   the `implemented ∧ ¬ready` drift alarm, and the `claim`/`observed` ladder already answers the liveness ask.*
-2. **File-level blast-radius reports its own coverage gaps.** An unanchored changed file is surfaced as an
-   explicit *coverage-unknown* item, never silently dropped; the MVP never claims exhaustive reach (that is the
-   deferred symbol-level impact graph). *Rejected: demoting blast-radius from the MVP — the honest-coverage
-   signal preserves it.*
-3. **`ready` = the structural floor + a human's `declared` statement.** "Reviewed in context" is **intended
-   human practice**, not a graph fact or a checked property (checking it would be the workflow-gating §0 guardrail
-   1 forbids); approval provenance, where it matters (a baseline), is **git-native** — a signed tag carries
-   approver + approved-at. *Rejected: an authored review/approval primitive with approver identity — it reverses
-   the one-primitive bet and the explicit "RBAC/approval outside the model" cut.*
-**Scope.** Applied to the **ratified base** (§4b, §6, §7, §8) plus the derived `02`/`04`/`05`/`06`/`07` +
-`jtbd-07` — tightenings of the base's own honesty ethos (§0 guardrail 1; §4b "readiness is stated, facts are
-derived"), not reversals of direction.
-**Forward note.** If multi-actor `ready` / baseline trust later becomes load-bearing, the guardrail-respecting
-home for approval provenance is **signed git tags** (identity + approved-at, already in git) — not a new authored
-primitive.
-
-### Base refinements (R-series)  [R1/R2 ACCEPTED & applied 2026-06-10 (Fold-A) · R3 see below]
-
-> **[RETIRE-AT-FOLD]** — pure change-log by the three-part test (the entries' own words: "the code already
-> conforms"); substance fully absorbed into the glossary, `01`, `03`, `04`. Kept until the decision-spec fold
-> because `04` §2 cites "DECISIONS R1"/"R3" live.
-
-**Context.** The post-Session-1 founding-ideation review surfaced two wording imprecisions in the ratified base.
-The **code already conforms** in both cases; these are language tightenings, so per the working discipline
-(terminology is ratified — *flag*, don't silently edit) they were recorded as **PROPOSED** and assessed by the
-post-split adversarial review as *already determined* (ratification, not deliberation). They were ratified and
-applied in the **pre-grill fold session (2026-06-10)** — R1/R2 during the Fold-A base restructure, R3 in Fold-B —
-rather than spending grill time on no-op-on-code wording. They are **not** model changes.
-- **R1 — harmonize "anchor carries identity only" (§2) with "anchored = a human binding" (§4).**  [ACCEPTED ·
-  applied] §2 said anchors carry "identity only," while §4's `claim` table called `anchored` "a human binding" —
-  and a binding (it emits a `satisfies`/`verifies` edge) is more than bare identity. Unified phrasing, now in the
-  glossary's `anchor` entry, `01` (epistemic boundary), and `04` §2: *"an anchor says 'this code location is the
-  implementation/test binding for this Spec ID'; binding only, never system-truth content — never behavior,
-  rationale, readiness, acceptance criteria, or delivery facts."* The code already conforms (anchors hold
-  only `id`/`label`/target; `@ts-expect-error` proves the rest is rejected).
-- **R2 — "no consumer reads source directly" → permit source *links*, forbid independent re-parsing.**  [ACCEPTED ·
-  applied] The principle (`03`/`05`/`06`) is right, but a Design Review linking to source locations *recorded in
-  the graph* is legitimate. Now stated in `01` P2 and `03` §4: *"Consumers may link to source locations recorded
-  in the graph; consumers must not independently parse source to derive their own model."* Matters when the
-  Slice-4 Design Review lands.
-- **R3 — reconcile `04`'s `specTest` signature to binding-only.**  [ACCEPTED · applied 2026-06-10 (Fold-B)]
-  `04` §2 documented `specTest(id, { verifies, run })` with an executing `run` callback; the implementation
-  (`src/model/anchors.ts`) is identity-only (`{ id, label?, verifies }`, **no `run`**). The code is the *more*
-  faithful one: a binding anchor carrying `run` would couple the graph binding to execution, contradicting
-  "the graph records that an enabled verifier *exists*, never that it ran" (§4b / MD-7). A **doc fidelity bug,
-  not a code gap** — `04` §2 now shows the binding-only signature matching the code. Same pattern as R1/R2
-  (the code already conforms). Surfaced by the post-Session-1 adversarial review (F6).
-
-### Scope note — relationship to the prior plan & brief
-**Adopt-the-nouns reversal (kept for the record).** An earlier brief held "the Protocol is **not** a PM tool; do **not**
-adopt SAFe/PM ladder names." MD-2 **reverses** that: the commercial Studio means users must not relearn delivery
-vocabulary, so the Protocol adopts the established delivery **nouns** (as projections + vocabulary) and rejects only the
-process **gating** FSM. The structural decisions **D1–D6** (recorded below) **still hold**, reframed under the meta-model
-(MD-1); the cleanup plan that applied the ratified language across the 18 concept/JTBD docs was **executed and
-retired** (2026-06-07). The first-draft input drafts (`GLOSSARY.md`, `UBIQUITOUS_LANGUAGE_{1,2}.md`) and the language-finalization
-brief have since been **deleted** (consolidated); the **sole canonical base is
-`docs/concept/ubiquitous-language.md`.**

-## 2026-06-10 — Session: pre-grill folds (Fold-A · Fold-B · archive)
-
-> The fold session prescribed by `plans/04` §3: restructure the language base (Fold-A — the UL doc became
-> the lean glossary; model exposition rehomed into `00`–`07`), ratify-and-apply the R-series (above), fold
-> the already-determined items out of the grill agenda (Fold-B — the two entries below), and archive the
-> review artifacts into tracked `reviews/`. The grill (`plans/03`) now opens onto a lean base and only
-> genuinely-open decisions.
-
-### MD-8 — Generic-anchor DSL shape: one `codeAnchor` over the implementation-flavored code namespaces  [ACCEPTED 2026-06-10 · FOLDED at Slice 2 — the rationale lives on the `codeAnchor` builder doc-comment (`src/model/anchors.ts`); kept as the historical record]
-**Decision.** Generalize `anchorImplementation` into a **`codeAnchor`** builder (plus branded id) accepting the
-implementation-flavored code namespaces — **`impl` / `api` / `component`** — so a *generic* anchor can bind any
-code location (class, function, route, module) as the base requires.
-**Why / alternatives rejected.** Anchors are generic *by definition* (`04` §2 — the binding is the thing,
-framework- and location-neutral), and the ID grammar already parses any lowercase namespace; only the builder +
-branded id are namespace-locked today. The base therefore already forces this answer — the post-split
-adversarial review assessed it "resolvable now," so it is recorded here rather than spending grill time.
-*Rejected:* per-namespace sibling builders (`anchorApi`, `anchorComponent`, …) — surface bloat for zero
-expressive gain.
-**Execution.** Rides Slice-2 anchor extraction, together with the example's missing api/route anchor
-(`plans/02` H10). *(This is the item the plans' open-decision code-space called "D6" — not the legacy
-structural D6 below; lead with meaning.)*
-
-### MD-9 — Open-questions canonical home: `intent.openQuestions`  [ACCEPTED 2026-06-10]
-**Decision.** Blocking open questions live in **`intent.openQuestions`** — the honesty check (no stated
-`defined`/`ready` with a blocking open question) must read them there.
-**Why.** The base is unambiguous (`02` §3: `intent` carries `openQuestions`, flaggable `blocking`; the `04`
-worked example authors them under `intent`). The Session-1 pre-plan drifted — the implemented floor data reads
-`design.openQuestions` / `decision.openQuestions`, so a doc-following author's blocking question never fires
-the marquee honesty check. The fix direction is determined **regardless of how sections get typed** (the
-typed-sections grill decision only shortens the predicate), so it is recorded now rather than gated on it.
-**Execution.** Stays `plans/02` Wave B (H2): read from `intent.openQuestions`, update the floor data's
-`authoredPaths`, flip the gated should-fail fixture active.
-
-## 2026-06-10 — Session: the grill (decision resolution on the lean base)
-
-> The fresh `grill-with-docs` session prescribed by `plans/04` §5, agenda `plans/03`: the six genuinely-open
-> decisions (plans' open-decision handles D1–D4, D7, D8 — not the legacy structural D-space below), resolved
-> against the lean base, ratified inline. Base edits land in `02`/`04`/`05`; terms in the glossary; Wave B
-> (`plans/02`) rewritten execution-ready at the end.
-
-### MD-10 — `behavior` sections carry content only; linkage lives in relations  [ACCEPTED 2026-06-10]
-**Decision.** `behavior.rules` and `behavior.examples` hold **content, never spec refs**: rules are prose;
-an examples entry is prose **or** a structured `{ given, when, then }` object (the entry matures *in place* —
-prose → structured GWT). The section ⟷ kind duality rule (`02` §3) extends to `rule`/`example`: **promotion is
-exclusive** — promoting an entry to a standalone `rule`/`example` spec *moves* the content out, and the only
-linkage is the child's `refines`/`verifies` relation (a reverse-edge query, never an authored ref list).
-**Why / alternatives rejected.** The repo had the same two fields authored three incompatible ways (refs in
-`create-order`; prose + redundant flat GWT in `valid-cart`; prose/refs mixed in the docs), and the ref form
-double-linked the same fact (parent's `behavior.rules: [ref(rule)]` *and* the rule's `refines(parent)`) with
-nothing naming the linkage of record — latent drift, against ambiguity-is-loud (L2). Content-only applies the
-already-ratified duality rule instead of inventing shape. *Rejected:* a `prose | ref` union (formalizes the
-duality, every consumer branches, double-linkage stays legal); refs-only (every two-line rule costs a full
-spec — the heavy-authoring loop `plans/03` §2 warns about).
-**Consequences.** GWT's canonical home is **nested in the examples entry** (the flat `behavior.given/when/then`
-the floor overlay reads today is Session-1 drift — reconciled in Wave B). Section-embedded referential
-integrity (plan 02 H4) **dissolves for `behavior`** — there are no refs to check. The readiness floor must
-count promoted children as evidence so promotion never costs a spec its earned rung (MD-12/D7, `05` §3).
-**Execution.** Wave B: type `BehaviorSection` to this shape (D1), re-author the example (drop ref lists from
-`create-order`; drop `valid-cart`'s redundant prose entry; nest its GWT), repoint the `example` overlay clause.
-
-### MD-11 — The typing law: floor-bearing sections are closed-typed; `decision.status` rejected  [ACCEPTED 2026-06-10]
-**Decision.** Sections get typed by a **criterion, not a list**: *every floor-bearing section* — one a
-readiness-floor clause reads as evidence — gets a **closed typed shape** (no index signature). Today that is
-six: `intent`, `behavior` (per MD-10), `constraints[]` (array, per `02` §1 / plan 02 H3), `model`,
-`verification`, and `decision` (pulled in because the kind-aware floor, MD-12, makes it the natural evidence
-of `decision`-kind specs). `design` and `ui` stay open bags — genuinely-unsettled surfaces keep breathing
-(L9). The criterion outlives the list: a section becomes typed when a floor clause starts reading it.
-**Why / alternatives rejected.** Closed shapes are simultaneously the honesty fix (the in-section bypass
-`behavior: { "has-verifier": true }` stops typechecking — the type level closes what the H8 gated fixture
-locks) and the single highest-value adoption lever (autocomplete + shape guardrails against the
-heavy-authoring loop, `plans/03` §2). *Rejected:* the carried "five" list (same intent, but a list goes stale
-the moment the floor moves — D7 proved it immediately); all eight (commits architecture/UI surfaces that are
-not settled); none + a runtime authoring-shape validator (no guardrails, the tracer bullet keeps proving
-nothing about shape).
-**`decision.status` is rejected vocabulary** (glossary ledger): the adoption arc is the envelope's
-`readiness` (raised → explored → written → ratified, floor-checked); replacement is `supersedes`; a rejected
-path is not a truth-spec — it lives in the chosen decision's `alternatives`/`consequences`. The example's
-`decision.status: "accepted"` is Session-1 drift, cleaned in Wave B.
-**Execution.** Wave B types the six in `sections.ts`, drops the `constraints` record-form handling
-(validators stop string-probing), re-authors the example, and flips the gated H8 fixture
-`invalid-hand-authored-delivery-fact-in-section` active.

-### MD-12 — The readiness floor's evidence clause is kind-conditional at both rungs; overlays dissolve  [ACCEPTED 2026-06-10]
-**Decision.** The floor splits into **kind-blind structural clauses** (envelope at `idea`; `intent.outcome` +
-≥1 relation at `scoped`; no blocking open questions at `defined`+; resolution clauses at `ready`) plus **one
-kind-conditional evidence clause**: `scoped` = the kind's natural evidence is *present* (prose acceptable),
-`defined` = the evidence is *complete* where the kind defines a stronger form (structured GWT for `example`,
-machine-readable `target` for `constraint`, the written choice for `decision`). The separate overlay
-mechanism is dissolved into the per-kind evidence table (`05` §3). Three bounding laws: monotonic by
-construction (every `defined` cell implies its `scoped` cell), promotion-neutral (promoted forms count —
-MD-10), convergence is honest (`rule`/`model` rungs converge rather than become quotas). `contract` maps to
-the behavior-family row as a **documented interim** with a named deferral: when a dedicated contract section
-lands, the typing law (MD-11) pulls it in and the row repoints.
-**Why / alternatives rejected.** The review's top finding (F1), extended one rung down by the grill: the
-plan's defined-only sketch would NOT have de-padded the example, because floor clauses are cumulative and
-`scoped`'s kind-blind `rules-examples-or-constraints` clause is what `order-model` (`model.terms` counts for
-nothing) and `order-lifecycle` (the `decision` section counts for nothing) were padding for. The old floor
-was also non-monotonic for `constraint` (its natural evidence stopped counting between `scoped` and
-`defined`) — half-delivering the P8 "kind changes required detail" promise: at the floor, `kind` only ever
-*added*. *Rejected:* defined-only (leaves the padding one rung lower); dropping evidence below `ready`
-(guts the honest-readiness differentiator — `defined` would stop meaning anything checkable).
-**Consequences.** The canonical example de-pads — the throwaway `behavior.rules` on `order-lifecycle`,
-`order-model`, and `order-latency-constraint` are deleted, and `checkout-v1.test.ts` stops asserting padding
-is green. An AI author no longer learns to sprinkle `behavior.rules` onto decision records.
-**Execution.** Wave B rewrites `readiness-floor.ts` as the per-kind evidence table (with D3's
-table-as-single-source collapse), de-pads the example, and re-authors the H8 fixture
-`invalid-defined-constraint-without-target` (which itself currently pads).

-### MD-13 — The floor table in code is the single source of truth; the evaluator is generic  [ACCEPTED 2026-06-10 · status 2026-07-11: the one-validation-path re-key (MD-14, executed) moved predicate signatures from `(spec, model)` to `(node: PrimitiveNode, index: GraphIndex)`; the table / derived clause-id union / generic evaluator all stand — `src/validate/readiness-floor.ts`]
-**Decision.** `readiness-floor.ts` becomes the one home of the floor: each row carries `{ clauseId,
-description, predicate }` (a named predicate from a small library, with paths as arguments where presence
-*is* the check); the per-kind evidence map (MD-12) lives beside the clauses; the clause-id union is
-**derived** from the table via `typeof`, never re-enumerated; the evaluator is one generic loop. Evidence
-predicates take `(spec, model)` — promotion-neutrality (MD-10/MD-12) needs the authored model to see
-refining children. Decorative metadata is banned: `authoredPaths` either becomes a real predicate argument
-or is deleted.
-**Why / alternatives rejected.** 453 lines for three checks; clause ids enumerated in four places (add a
-clause → edit 3–4 spots; miss the switch and it **silently skips** — a validator that silently stops firing
-is exactly what `05` §5 exists to prevent); `authoredPaths` was verified decorative. Table-as-truth also
-buys doc↔code fidelity: `05` §3's tables and the data table are reviewable as mirror images. *Rejected:*
-evaluator-as-truth (the doc table would mirror a switch; the sync burden survives); minimal trim (the
-silent-skip failure mode survives).
-**Execution.** Wave B (plan 02 H5), together with the MD-12 floor rewrite — one change, since the table
-being rewritten is the table being collapsed.
-
-### MD-14 — One validation path, through the one graph; `AuthoredModel` retires as a public seam  [ACCEPTED 2026-06-10 · EXECUTED — the extractor landed at Slice 1, the graph-validator re-key at Slice 3; `AuthoredModel` is deleted and `validateGraph` is the sole validation seam]
-**Decision.** When the extractor lands, validators consume **the extractor's output** — one path: source →
-extract (static reification, P5) → graph (in memory) → conformance + honesty checks; `sdp validate` =
-`sdp build` + checks. `AuthoredModel` is demoted to (at most) an extractor-internal intermediate — never a
-second public validation seam, never a "pre-graph lint" mode. Authoring-time feedback is owned by typed
-sections + `tsc` (MD-11) and the `sdp/spec-static` lint, not by a parallel validator path.
-**Why / alternatives rejected.** Sharper than the "two paths drift" worry: the two ingestion modes can
-**disagree** — the Session-1 harness validates *imported, evaluated* spec objects, while the extractor
-*statically reifies without executing* (`04` §1). A non-static expression evaluates to a value on import but
-drops in reification, so import-path validation can pass a spec the graph doesn't hold — honesty checks
-validating a phantom. The protocol's truth is what source *statically states*, not what it *evaluates to*.
-This also makes the crippled-graph gap strategy's minimal slice ("extract → graph, no more," `plans/04` §2)
-sufficient for self-validation. *Rejected:* a documented dual path (the disagreement above, institutionalized).
-**Execution.** Slice 1 (extractor feeds the floor checks) / Slice 3 (the full gate); until then the Session-1
-harness stands in, honestly fenced (the `authored-model.ts` doc-comment already says so).
-
-### MD-15 — Authored Spec files carry the `.sdp.ts` extension  [ACCEPTED 2026-06-10 · amended 2026-07-18 (plan 17) — re-pointed, not repealed]
-**Decision.** Spec files are `/specs/**/*.sdp.ts` (packs: `*.pack.sdp.ts`). The Protocol's own compound
-extension — the `.stories.tsx` pattern: tool-branded, collision-free, tooling-scopeable. The model name
-`Spec` is untouched (it was always settled); only the file serialization changes.
-**Amended 2026-07-18 (plan 17) — re-pointed, not repealed.** The rationale below (never `.spec.ts`;
-a tool-branded, collision-free compound extension; the filename itself carrying the marker for a
-colocated future) carries over to the ruled carrier: a Markdown-carrier Spec file is
-`/specs/**/*.sdp.md`. `.sdp.ts` remains the extension of the TS DSL carrier while that carrier
-survives — the import source and lawful per-ID option (the carrier ruling, MD-18).
-**Why / alternatives rejected.** `*.spec.ts` is *the* default test glob of the JS ecosystem (Vitest:
-`**/*.{test,spec}.?(c|m)[jt]s(x)`; Jest/Mocha conventions match). An adopter on runner defaults gets their
-runner executing Spec-primitive files — Vitest fails files with no test suites, so first contact with the
-Protocol is a baffling CI failure. This repo's own narrowed `vitest.config.ts` was the dodge that proved the
-landmine. Decided now, while the rename costs nine example files and zero adopters. *Rejected:* keep +
-documented exclusion (pushes a config edit onto every adopter, and IDE test explorers keep mislisting spec
-files); `.spec.sdp.ts` (collision-free but verbose self-restatement); directory-convention-only (identity
-lives only in the path — future colocated specs would carry no marker).
-**Execution.** Wave B renames the example files and this repo's docs/globs; the extractor (Slice 1) ships
-reading `*.sdp.ts` from day one.

-## 2026-06-10 — Session: Wave B execution + post-execution adversarial pass
-
-### MD-16 — Honesty-sharpenings from the post-Wave-B adversarial pass: promoted evidence must be carried; authoring-shape gets its runtime stand-in; `doc:` targets are an explicit deferral  [ACCEPTED 2026-06-10]
-**Context.** An adversarial review (Codex) of the executed Wave B challenged three honesty surfaces:
-(1) the promotion-neutral floor counted *any* refining `rule`/`example` child and *any* `constrainedBy`
-edge as evidence — an empty stub child or a wrong-kind edge could clear a parent's `scoped`/`defined`;
-(2) MD-11's closed sections rely on TypeScript's excess-property check, which fires only on fresh
-literals — a section assembled through an intermediate variable smuggles a delivery fact past `tsc`,
-and nothing caught it at runtime before Slice 3; (3) the base's `decidedBy` → external `doc:` ADR
-affordance (`02` §6) is unrepresentable in the DSL, making the F2 doc-note close-out read stronger
-than its scope.
-**Decision.** All three resolved as honesty clarifications consistent with the settled decisions:
-1. **Promoted evidence counts only when the promoted spec itself carries its kind's evidence** (its
-   `scoped` cell in the per-kind table): a refining `rule`/`example` child must hold its
-   statement/entry; a `constrainedBy` edge counts only when it resolves in the model to a
-   `constraint`-kind spec with non-empty `constraints[]` (the section ⟷ kind twin of inline
-   `constraints`). Follows from MD-10 — promotion *moves content out*, so an empty child is not a
-   promotion but a stub. *Rejected:* requiring a minimum child **readiness** (a cross-spec readiness
-   gate below `ready` — the base reserves cross-spec rungs for the deferred `ready` clauses, and
-   readiness is the author's statement, not structural evidence); counting `rule`-kind `constrainedBy`
-   targets in the constraints-evidence slot (the duality twin of `constraints` is `constraint`;
-   additive to relax later if real usage wants it).
-2. **Authoring-shape honesty (`05` §2, check 5) gets its Session-1 runtime stand-in now**:
-   `validateAuthoringShape` fails any spec or pack that hand-authors a delivery-fact key
-   (`implemented` / `has-verifier` / `observed`) at the envelope or inside any section. Not a second
-   validation path (MD-14): it is an MVP honesty check implemented early on the same stand-in harness
-   the readiness floor already rides, and it migrates onto the graph with the rest. The type-level
-   closure (MD-11) stays the ergonomics lever; its fresh-literal scope is now recorded for sections
-   exactly as F7 recorded it for the envelope, and the bypass is pinned twice (compile-time +
-   runtime fixtures).
-3. **`doc:`-target relations are an explicit named deferral**, stated where the affordance is promised
-   (`02` §6, the glossary's flagged ambiguities, and doc notes in `ids.ts`/`relations.ts`): the DSL
-   stays `spec:`-target-only until the external-ADR need arrives. F2 stays closed *as the doc-note it
-   was scoped to be*; implementing a `DocId` target type now was rejected (no call site wants it, and
-   the shape should be decided when `doc:`/pack-targeting actually arrive).
-
-**Status (2026-07-11).** Point 2 executed differently in detail once the one-validation-path re-key
-(MD-14) landed: the check is named **`checkAuthoringShape`** (not `validateAuthoringShape`) and lives
-on the graph inside `validateGraph` (`src/validate/validators.ts`) — the stand-in harness it was born
-on is deleted. It also **split**: the envelope/top-level delivery-fact rejection moved into the
-extractor (`extract/reserved-property`), so the validator scans section interiors only. Points 1 and 3
-landed as written.
-
-## 2026-07-11 — Session: plan 12 run (the universals ratified · the carrier competition opened)
-
-> The session's full record — the seven ratified settlements, the carrier-competition restructure,
-> the exhibit bar, sequencing, and the law rulings that needed no new entry (JS-B2.3 kept: A2 is the
-> generated-union route the base already designed in, so the collision existed only under the dead
-> A1; dual-source ruling deferred to the carrier ruling session; MD-15 untouched) — lives in
-> **plan 12 §8**. Only one ruling passed the three-part test and enters here.
-
-### MD-17 — One point per example; tables are surface sugar  [ACCEPTED 2026-07-11]
-**Context.** The ratified example-space design (plan 12 §7, settlements 7–9) has an `example`-kind
-child bind a **point** in its parent's typed example space, and the coverage machinery counts each
-example as the **witness** of one outcome class. A consumer-corpus reread of gen-1 usage in a
-production project surfaced a colliding house style: the dominant authoring pattern there (93 of 132
-executable features) is **one scenario asserting a whole truth-table** — many cases, one authored
-unit. Forcing one authored spec per case would make a 10-row table ten sibling files and fight how
-authors demonstrably think.
-**Decision.** The graph model stays **one bound point per `example`** — the concreteness law and
-one-witness-per-class coverage semantics stay unconditional. A table of cases is **authoring-surface
-sugar**: a carrier may offer table syntax that **statically expands to N sibling examples at
-extraction** (the same move the import mapping already proved for Scenario Outline `Examples` rows),
-and renderers may project a sibling set back as a table — so authors keep the compact view at both
-ends while the graph never holds a multi-point example.
-**Why / alternatives rejected.** *An example may bind a point set*: keeps file counts down on every
-surface but makes the concreteness law and witness semantics conditional everywhere — the machinery
-pays forever for an authoring convenience one layer can absorb. *Strictly one point, no sugar*:
-purest, but contradicts the observed house style and taxes the gen-1 migration corpus. The chosen
-shape repeats the base's settled pattern — the model keeps the honest shape; surface layers translate
-both directions statically (natural-language step reading is the renderer's job; table authoring is
-the carrier's expansion sugar).
-
-## 2026-07-12 — Session: plan 16 run (the carrier ruled · prose ownership ruled)
-
-> The session's full record — the evidence table, the grounds, the re-dismissals by name, the
-> doc-repair bill, and the scheduled sessions — lives in **plan 16** (the session record of

-> session. Two rulings passed the three-part test and enter here.
-
-### MD-18 — The carrier ruling: Markdown, all eight kinds; the TS DSL becomes import source + per-ID option  [ACCEPTED 2026-07-12 · transition clause amended 2026-07-18 (plan 17)]
-**Context.** The carrier competition (plan 14) closed with four evidence PRs: two full exhibits
-(F2 Markdown, C2 own grammar) and two honest concessions (Gherkin extension/fork; typed markup).
-The docket required ruling the carrier, the kind-partition question, and the TS DSL's long-term
-role — evidence-vs-evidence on the recorded scorecards, never by preference.
-**Decision.** The **Markdown carrier (F2) is the authoring carrier for all eight `kind` values**:
-an authored `Spec` document is an `.sdp.md` file — YAML-frontmatter envelope, free prose body,
-the owned notation in fenced blocks — statically extracted into the one graph. **Transition
-clause, amended 2026-07-18 (plan 17):** New spec IDs may be born Markdown-canonical once the
-product parser lands; pre-existing IDs and the worked example remain TS-canonical until the
-ruled flip (the product parser, `sdp import`, and the checkout-v1 migration). After the flip
-the TS DSL survives as the import source and as a lawful per-ID option via the canonical-surface
-config (`04` §1) — the surviving law is **one canonical surface per ID, no mixing**, never
-TS-as-sole-surface.
-**Why / alternatives rejected.** *C2 own grammar*: strongest differentiation and diff/merge, but
-its own scorecard's ownership row is decisive — parser, formatter, highlighting, rendering,
-editor integrations, LSP owned forever, plus the agent grammar-context tax and no rendered page
-without our tooling. *Kind-partitioned dual carrier* (first-class per the docket, not a
-fallback): declined on the exhibit's own evidence — the structure-heavy `model` port was
-field-exact in Markdown, so a permanent two-surface partition buys nothing it can show; the
-per-ID config stays designed-in, retained not exercised. *Retiring the TS DSL outright*: burns a
-designed-in escape hatch for no honesty gain — the gen-1 disease (MD-1's gloss) was dual-source
-binding invisible to the type system, which the per-ID law already prevents. Hard to reverse:
-every authored spec, the parser, `sdp import`, and the doc corpus build on the ruled carrier.
-
-### MD-19 — The prose-ownership law: owned prose in the graph, on typed owners  [ACCEPTED 2026-07-12]
-**Context.** The F2 exhibit counted four prose paragraphs its spike deliberately dropped at the
-graph seam and named three MD-10-compatible homes (heading-path-keyed content section ·
-description on the owning typed section · file-only with a pointer). A document carrier winning
-made this ruling due, per the docket.
-**Decision.** Free prose enters the graph as **description values on typed owners** — the owning
-typed section, or the `Spec` itself (a spec-level narrative slot; epic-altitude navigational
-prose lives there beside `refines`). No parallel heading-keyed store; no file-only pointer. The
-deterministic ownership rule for edge text (before the first heading, between sections, under
-unrecognized headings) is a first-class deliverable of the surface-design session; until it
-lands, unowned prose is refused loudly (ambiguity-is-loud), never silently dropped.
-**Why / alternatives rejected.** *File-only + pointer*: consumers may link to source but never
-re-parse it (P2) — a pointer forces every prose-needing projection to re-parse or omit; dead on
-the graph law. *Heading-path keys*: gen-1 delivery experience (reviewed direction-level; no gen-1
-artifact cited durably) shows heading structure is what churns hardest across readiness
-promotions — sections born, renamed, killed — so heading-keyed content breaks identity exactly
-where enrich-in-place lives; and prose without a typed owner is where transcription bloat grew.
-Owned descriptions are MD-10-clean (content, never refs) and MD-11-aware: they land inside
-already-closed shapes, and any prose slot a floor clause ever reads gets pulled into the closed
-type as the typing law demands. Trade-off accepted: the ownership rule is real design work — paid
-once, at the surface-design session, instead of forever in an informal transfer checklist.
-
-## 2026-07-18 — Session: plan 17 execution (the self-hosting phase's pre-Gate-4 docket close)
-
-> The phase's full record — the corpus, the executable loop, the four owner gates, and the
-> docket — lives in **plan 17** and its execution branch. Plan 17 §3 flagged two rulings as
-> likely diary-worthy; both passed the three-part test at the pre-Gate-4 disposition and enter
-> here. The remaining §3 rulings stay in the corpus specs, the pinned tests, and the plan's
-> running log by deliberate omission.
-
-### MD-20 — The strict consumer-exclusion contract: root-relative POSIX path-prefix, never basename-anywhere  [ACCEPTED 2026-07-18]
-**Context.** Self-hosting forced the configurable extraction exclude the discovery code had
-deferred to external adoption: a root build must keep `explorations/` and `examples/` out of the
-Protocol's own graph. The fixed tooling excludes match basename-of-directory; the consumer rule
-was the open question.
-**Decision.** Consumer excludes (`--exclude` on `build`/`validate`/`view`;
-`ExtractOptions.exclude`) are strict, case-sensitive, root-relative POSIX path-prefixes —
-rejecting empty, `.`, leading `./`, terminal `/`, absolute, `..` segments, empty internal
-segments, and backslashes; deduplicated; nonexistent and file prefixes allowed; unioned with
-(never replacing) the fixed tooling excludes, which stay basename-of-directory.
-**Why / alternatives rejected.** *Basename-anywhere, for consistency with the tooling excludes*:
-convenient, but it silently skips a future nested `src/examples/` — consumer excludes are scope
-decisions, and scope deserves paths, not names. Hard to reverse: a public CLI/options surface
-consumers script against. Trade-off accepted: consumers must be explicit; precision beats
-convenience.
-
-### MD-21 — The envelope-grammar ownership posture: the contract is ours, the YAML library is a swappable representation (exact `yaml@2.9.0`)  [ACCEPTED 2026-07-18]
-**Context.** The Markdown envelope needed a YAML boundary, and the library's own current
-documentation no longer promises that parsing never throws — a permissive parse would make the
-envelope's meaning a library behavior rather than a Protocol-owned grammar.
-**Decision.** The Protocol owns the envelope grammar as an authored contract spec plus a bounded
-parser policy — failsafe schema, exactly one nonempty document, manual AST/CST mapping (never
-`toJS()` before policy validation), every warning/directive/tag/anchor/alias/merge/complex
-key/non-string scalar refused, byte/depth/node/scalar/finding caps — and pins the representation
-exactly: `yaml@2.9.0`, no semver range; the library stays a swappable representation behind the
-owned contract.
-**Why / alternatives rejected.** *Permissive parsing + a semver range*: broader YAML acceptance
-and free patch upgrades, but the grammar's meaning would drift with the library and adversarial
-input would meet an unbounded parser. *An own YAML parser*: total ownership, but it re-opens the
-dismissed own-grammar economics (the carrier ruling, MD-18). Hard to reverse: the corpus is
-authored against the owned contract and consumers see its finding IDs. Trade-off accepted:
-corpus-scoped strictness — full YAML/CommonMark parity is deliberately not claimed.

-## Structural-decision shorthand (D1–D6)  [ACCEPTED · relocated here when the cleanup plan was retired, 2026-06-07]

-> These six labels come from the original structural-decisions pass. Their *content* is canonical in the
-> design docs (`00`–`07` — since the Fold-A restructure rehomed the base's model exposition there); this table

-> single-use cleanup plan (which previously held it) is gone. **Do not confuse this legacy D-space with the
-> open-decision handles D1–D8 used by `plans/02`/`plans/03`** — those name the post-Session-1 grill agenda
-> (typed sections, prose-vs-ref, floor collapse, …), a different code-space; in prose, lead with meaning.
-> **[KEEP for traceability]** — at the decision-spec fold, **D3** (Pack reified), **D5** (the agent surface
-> scripts the graph), and **D6** (the MCP-deferred *no*) become decision specs of their own; the table

-Determinism is checkable, not promised: `--check-clean` on any command runs the pipeline twice
-independently and fails on a single divergent byte — across the graph, every contract module, and
-the review — and `npm run check:example` gates CI on exactly this over this example. Deleting
-`generated/` and rerunning reproduces the same bytes, and so does the pipeline run from a copy at

 ## Break it on purpose
 
-The fastest way to understand the checks is to trip them. Each experiment is one edit; revert
-with `git checkout -- examples/checkout-v1` afterwards (the next `build` regenerates
-`generated/`).
-
-- **Dangle a reference.** In `specs/orders/create-order.sdp.ts`, misspell the `refines` target
-  (e.g. `spec:orders.order-managment`). `validate` exits 1 with
-  `conformance/referential-integrity` — and suggests the id you meant.
-- **State readiness you haven't earned.** Add a blocking open question to `create-order`'s
-  intent — `openQuestions: [{ question: "Do guest carts create orders?", blocking: true }]` —
-  while it states `defined`. `validate` exits 1 with `honesty/readiness-floor`, naming the
-  failing clause (`no-blocking-open-questions`): readiness is stated by the author, checked
-  against the floor.
-- **Unbind the test.** Delete the `specTest` anchor from
-  `test/orders/create-order.valid-cart.test.ts`. The summary line drops to
-  `4 anchors → 16 nodes · 31 edges`, the valid-cart example stops being an enabled verifier, the
-  parent loses its verifier binding, and two more warnings appear: a second
-  `conformance/verifies-linkage` (valid-cart's own declared `verifies` no longer confers
-  anything) and `honesty/gaps` (valid-cart states `ready` with no resolving verifier) — still
-  exit 0, because a missing verifier is a surfaced gap, never a gate.
-- **Hand-author a delivery fact.** Add `"has-verifier": true` inside any section of a spec. The
-  closed section types reject it (`npm run typecheck:examples` fails), and even smuggled past the
-  types it fails `validate` with `honesty/authoring-shape` — delivery facts are derived, never
-  authored.
-- **Drift the authored value.** In `specs/orders/create-order-valid-cart.sdp.ts`, change
-  `{total: 100}` to `{total: 120}` and rerun `build`. The bound test fails with zero test edits —
-  `at step: Then an order is created with total 120` · `expected 100 to be 120` — because the
-  assertion reads `params.total` from the regenerated contract: the spec's value is the truth the
-  test enforces, and the failure speaks spec language. (Rename the step instead — in the parent's
-  vocabulary and the child's use — and `tsc` rejects the test's stale handler key by name.)
-- **Unbind a slot.** In the same spec, change `{n: 2}` to `{n}`. The **concreteness law** fires:
-  an unbound slot in a _used_ step caps the example below `defined`, and valid-cart states
-  `ready` — so `validate` exits 1 with `honesty/readiness-floor` (failing clause
-  `kind-evidence-complete`), and the contracts stage withholds the non-concrete example's step
-  contract (2 modules, not 3).
+The fastest way to understand the checks is to trip them. Each experiment edits a `.sdp.md` Spec.
+Revert the edit afterwards. The next `build` regenerates `generated/`.
+
+- **Use an unknown heading.** In `specs/orders/order-total-rule.sdp.md`, change `## Rule` to
+  `## Rul`. `validate` exits 1 with `extract/unrecognized-heading` and suggests `Rule`.
+
+- **Dangle a reference.** In `specs/orders/create-order.sdp.md`, misspell the frontmatter
+  `refines` target, such as `spec:orders.order-managment`. `validate` exits 1 with
+  `conformance/referential-integrity` and suggests the intended ID.
+
+- **State readiness you have not earned.** In `specs/orders/create-order.sdp.md`, add a blocking
+  open question under `## Intent` while the Spec states `defined`.
+
+  `validate` exits 1 with `honesty/readiness-floor` and the `no-blocking-open-questions` clause.
+
+- **Drift an authored value.** In `specs/orders/create-order-valid-cart.sdp.md`, change
+  `{total: 100}` to `{total: 120}`, run `build`, then run the bound test.
+
+  It fails without a test edit because the generated contract supplies `params.total`.
+
+- **Unbind a slot.** In the same Markdown Spec, change `{n: 2}` to `{n}`. `validate` exits 1 with
+  `honesty/readiness-floor`, citing `kind-evidence-complete`, and contract generation withholds
+  that example's step contract.

 **Acceptance criteria:**
 1. A spec can be created at `readiness: "idea"` with only `id`, `title`, `kind`, `altitude`, and either `intent.outcome` or a parent relation — nothing else is required.
-2. The new spec lives in a carrier document under the extraction root (conventionally `/specs/`) — `*.sdp.md` for a Markdown-canonical ID (new IDs may be born Markdown-canonical now that the product parser has landed — the interim carrier rule, MD-18), `*.sdp.ts` for a TS-canonical pre-existing ID — as committed content, immediately part of the single source of truth — no status field, ticket, or external tool is needed for it to "exist."
+2. The new spec lives in a carrier document under the extraction root (conventionally `/specs/`) — Markdown `*.sdp.md` by default, with `*.sdp.ts` lawful per ID — as committed content, immediately part of the single source of truth — no status field, ticket, or external tool is needed for it to "exist." Specs default to Markdown; Packs remain TS until a Pack syntax ruling; the TS DSL survives as import source and a lawful per-ID option (the carrier ruling, MD-18).
 3. Open questions can be attached (`intent.openQuestions`) without resolving them and without blocking capture; only questions explicitly marked `blocking` constrain stating `defined`/`ready` later.
 4. The spec is valid at its lowest readiness — the build never demands rules, anchors, or tests to accept an idea.
 5. The spec source is static, side-effect-free data in its carrier ("a JSON file that TypeScript happens to validate" in the TS carrier; bounded frontmatter and owned prose in the Markdown carrier), so the extractor reifies it deterministically.

+
+> **Status: 🧭 BRIEF — planning input, not an execution plan.** This is the owner's commissioning

+
+## 1. The goal in one paragraph
+
+Phase 1 made the Protocol's own delivery model a first-class citizen of its own machinery — 15
+Markdown-canonical specs, one pack, an executable tracer, the full repository gate. But the repo
+still runs a **three-state carrier world** (Markdown-canonical new IDs · TS-canonical pre-existing
+IDs · the TS checkout example), the decision diary still carries sixteen durable rulings as prose
+with a divergent reserved namespace, and most of the concept corpus (`docs/concept/00–07`) still
+holds semantic contract no spec carries. Phase 2 collapses the carrier world to one rule
+(Markdown canonical by default, the TS DSL surviving as import source and per-ID option), folds
+every durable decision into a `decision`-kind spec under a strict durability rubric, and grows
+the corpus one subsystem at a time so concept-doc content starts living as typed, anchored,
+checkable Specs. The flip is the precondition for the rest: the corpus cannot absorb the concept
+docs while three carrier states coexist.
+
+## 2. Settled ground the plan builds on (read, don't re-derive)
+
+- **The carrier ruling (MD-18)**, transition clause as amended by plan 17: new spec IDs may be
+  born Markdown-canonical; pre-existing IDs and checkout-v1 stay TS-canonical **until the ruled
+  flip** — the product parser (landed), `sdp import` (not started), and the checkout-v1 migration
+  (not started). Surviving law: **one canonical surface per ID, no mixing**. The interim records
+  are pinned by `check-carrier-interim.mjs` and stated in `AGENTS.md`, `CONTEXT.md`, and
+  DECISIONS MD-18 — all three must move together again at the flip (the operative-record gate
+  pattern, plan 17).
+- **The product Markdown parser** — corpus-scoped by design; the parser specs pin an explicit
+  **non-claim** of full refusal parity with the TS carrier. Gate 4 names discharging this (the
+  like-for-like parser-hardening baseline / C2-parity obligation) as part of the phase-2 effort.
+- **The self-hosting corpus**: 15 specs under `specs/` (carrier ×5, extraction ×3, validation ×3,
+  model ×1, protocol ×1, decisions ×2) plus `pack:self-hosting-v1`
+  (`specs/self-hosting.pack.sdp.ts` — the pack manifest lawfully stays TS, the
+  one-canonical-surface law being per-ID). `spec:carrier.sdp-import` is honestly authored at
+  `idea` and is tranche 1's spec to enrich in place.
+- **The fold seed**: the ratified-name registry (`docs/concept/DECISIONS.md` top) marks 16 rows
+  **durable** with reserved future IDs under `spec:decisions.*`, matching the two born decision
+  specs. The fold activates that ratified namespace. Rows marked *folded/folds* (MD-8, MD-9,
+  MD-13) already have carrying surfaces (doc-comments, `sections.ts`, the floor table) — verify,
+  don't re-fold.
+- **Open watch items** (rule only under fire, each ruling recorded): table-sugar syntax ·
+  the single-literal vocabulary form · the multi-entry constraint form · the array-section prose
+  sub-owner · Markdown `Pack` syntax. Gate 4 expects table sugar to fire in this phase — an
+  expectation on the record, **never a quota**: the sugar's semantics are already ruled
+  (point-per-example (MD-17): a table statically expands to N sibling examples), only the
+  Markdown syntax is unruled, and checkout today models multi-case as sibling `example` specs
+  without tables. If the grammar matrix never forces it, the watch item survives unfired
+  (acceptance 6).
+- **Deferred-debt tail**: plan 17 §6's review-06 reconciliation rows marked
+  `pre-existing/phase-2` or `deferred` (exclude UX diagnostics, Design Review escaping policy,
+  stale provenance wording, grammar-hardening polish, …). The plan must sweep this tail and
+  adopt the rows that naturally ride these tranches; the rest carry forward in the docket, never
+  silently drop.
+
+## 3. Scope — three tranches, one plan
+
+### Tranche 1 — end the interim carrier rule (the flip)
+
+Discharge the carrier ruling's transition clause completely. **Ruled order (§6): emitter →
+checkout migration → hardening baseline → flip** — grammar growth is forced by the migration,
+parity is paid once against the settled grammar, and the default never points at a surface that
+has not earned its hardening claim:
+
+1. **The `sdp import` emitter — a durable product verb (§6), never a migration script.**
+   Reified TS carrier → authored `.sdp.md`, honoring the ruled
+   grammar (envelope subset, heading → section map, `gwt`/`gwt-vocabulary` fences, prose
+   ownership). Enrich `spec:carrier.sdp-import` from `idea` upward only as the floor honestly
+   clears. Fidelity is proven by **round-trip graph equality**: import a TS spec, extract the
+   emitted Markdown, and compare graphs modulo explicitly ruled deltas (any delta is itself a
+   ruling to record, never a shrug). **Three bindings pinned here:** (a) the ratified glossary
+   already defines `sdp import` as *the one-way gen-1 `.feature` converter* (`CONTEXT.md`, the
+   executable half) — reusing the name for the TS→MD emitter is a **load-bearing glossary
+   amendment made on the record** (the natural reconciliation: one import verb, many source
+   adapters, sharing the glossary's own "document emitter authored once in the winning
+   carrier"; a distinct verb is the recorded alternative), never a silent CLI add-on — and the
+   phase-2 adapter inventory is **TS-only**, the gen-1 `.feature` source staying designed-in
+   and deferred on the record, never silently abandoned; (b) the round-trip **delta catalog is
+   pre-declared** in the plan (at minimum: the `file` path suffix `.sdp.ts`→`.sdp.md`; physical
+   envelope differences; TS source comments, which are not graph content; delivery facts
+   compared under the same anchor set) — equality is never redefined mid-flight; (c) fidelity
+   is **two-layered** — graph equality is the semantic gate only; the plan also sets an
+   authoring-surface bar (emitted Markdown idiomatic under the ruled grammar and the
+   prose-ownership law, judged at Design Review with fixture evidence), so round-trip green
+   never blesses unreadable Markdown no agent could have authored. One honesty note: the
+   per-ID option today is realized purely by *which file exists* (both surfaces for one ID =
+   the duplicate finding); the flip invents **no** canonical-surface config unless the plan
+   rules one as an explicit deliverable — and whichever way it rules, `04` §1's stronger
+   standing claim ("a per-ID canonical-surface config decides which surface is canonical; the
+   other is a generated read-only view") is reconciled on the record (repaired to aspirational
+   wording, or the minimal mechanism ships) rather than left contradicting the file-existence
+   realization.
+2. **The checkout-v1 migration.** Every checkout spec ID moves to `.sdp.md` via the emitter; the
+   TS spec carriers for migrated IDs are deleted **in the same change** — no mixed interval on
+   the branch history that `npm run check` ever blesses. The example's README walkthrough is
+   rewritten for the Markdown surface. Determinism stays regenerate-and-compare
+   (`--check-clean`), never committed goldens.
+3. **The parser-hardening baseline.** Convert the pinned non-claim into either (a) a
+   like-for-like refusal-parity claim with pinned evidence, or (b) a revised, explicitly scoped
+   non-claim recorded on the parser specs — never a silent lapse; the plan **defines the
+   evidence bar** (parity measured against the TS reifier's refusal behavior as a bounded
+   matrix — never open-ended "hardened"). The checkout corpus is the forcing function for
+   grammar growth: the plan inventories a **checkout grammar matrix** (kind × section ×
+   phase-1 support, against the real `examples/checkout-v1` tree — 11 specs across all eight
+   kinds) *before* scheduling any syntax ruling; whatever the matrix forces beyond the phase-1
+   subset gets ruled under fire and recorded, per the phase-1 discipline. The review-06
+   grammar-polish cluster rides this baseline (§6 debt intake).
+4. **The canonical-default flip — the tranche's capstone.** The default authoring carrier
+   becomes Markdown for all IDs; the TS DSL is **not retired** — it survives exactly as the
+   carrier ruling says, import source + per-ID option (the `.sdp.ts` extension law (MD-15)
+   already re-points to the `.sdp.md` sibling; check its wording again post-flip). The
+   post-flip operative sentence is honest about every residue: *Specs default to Markdown;
+   Packs remain TS until a Pack syntax ruling; the TS DSL survives as import source and a
+   lawful per-ID option.* The flip is
+   an **operative-record gate** mirroring phase 1's: DECISIONS MD-18's Decision text, the
+   `CONTEXT.md` resolved entries (the carrier row **and the amended `sdp import` term**), and
+   `AGENTS.md` land in one commit or a tight series with no intermediate green claim
+   contradicting them; the pinned consistency scripts (`check-carrier-interim.mjs`, plus the
+   interim/Gate-4 strings in `check-carrier-truth.mjs` and `check-self-hosting-gates.mjs`) are
+   **replaced by post-flip truth pins or retired** in the same series — the machine check that
+   records and law agree survives the flip; a **post-flip anti-misleading pass** repairs every
+   remaining interim-rule claim, its inventory seeded from `check-carrier-truth.mjs`'s audit
+   map (concept docs `00`/`04`/`07`/README, JTBD stories, the example README, MD-15's wording,
+   package docs).
+
+### Tranche 2 — the decision-spec fold
+
+Every **durable** row of the ratified-name registry becomes a `decision`-kind spec;
+`docs/concept/DECISIONS.md` shrinks to a **lean registry of pointers** (name · one-line gloss ·
+spec pointer · the folded/CONTEXT-only dispositions). The fold is governed by the routing rubric
+in §4 — it is a *distillation*, never a diary transplant:
+
+- **The namespace is ruled — `spec:decisions.*`** (§6). The fold's first act amends the
+  registry's "Future spec id" column to match; the two born specs keep their IDs and every
+  existing reference stands.
+- **Relation shape (§6):** each fold decision `refines` the most-specific subsystem spec it
+  rules (fallback: `spec:protocol.self-hosting` for genuinely phase-level decisions); specs a
+  decision shapes author `decidedBy` back-edges. The fold therefore runs **after** tranche 3's
+  parent-creating waves (execution order 1 → 3 → 2).
+- **Per-row disposition, recorded in a fold ledger** (a plan process record, not graph content):
+  each of the 16 durable rows plus the legacy structural shorthand (D1–D6) and the
+  measured-evidence section gets exactly one disposition — `decision spec` · `CONTEXT.md only`
+  (pure terminology) · `ordinary spec` (design intent, not a ruling) · `carried by code/tests —
+  verify the surface` · `retired (git is the archive)`. The *folds* rows (MD-9, MD-13) are
+  verified, not re-authored.
+- **The diary bodies retire once carried.** Git history is the archive of record; the plan
+  decides whether any body text moves to `reviews/`-style archive or is simply deleted with the
+  lean registry pointing at specs. What never dissolves: `CONTEXT.md` as the ratified glossary,
+  the lean registry itself, `plans/` as the process record.
+- **Not architecture-only.** The `decision` kind covers any durable delivery ruling — naming,
+  posture, dependency pins, process laws (the plain-language-references decision is the
+  template) — not merely architectural shape.
+
+### Tranche 3 — corpus expansion, one subsystem at a time
+
+Grow `pack:self-hosting-v1` beyond the 15 so concept-doc semantic contract is progressively
+carried by typed, anchored Specs — the dissolution decision
+(`spec:decisions.concept-docs-dissolve`) names the criterion; deletion stays out of scope.
+
+- **All four subsystem waves ride phase 2 (§6)**, sequential and owner-gated (one subsystem at
+  a time as working pace, never as phase scope): the core model (`02`) → `model`/`behavior`/
+  `rule` specs for the primitive, the three descriptors, sections, and relations · validation
+  (`05`) → `rule`-kind specs over the validator registry (11 check ids today) — a **pressure
+  target, never a count KPI**: bundling is lawful where one law spans several mechanical
+  checks (the anti-filler rule wins; acceptance 4's disposition-over-count spirit), floor
+  clauses as evidence · consumers (`06`)
+  → reader and projection specs · extraction and the one graph (`03`) → deepening the phase-1
+  seeds. The fold's refine-target minimum (core model · validation · a consumers parent) rides
+  the earliest waves so tranche 2 is never blocked.
+- **Anchored to the real engine.** Precise anchors on existing entrypoints keep `implemented`
+  derived and honest; readiness is stated only where the floor genuinely clears; a kind is
+  authored only where real content forces it (thin filler specs are a defect).
+- **Coverage trail.** Each new spec names, in the plan's coverage ledger (process record, never
+  graph content), which concept-doc sections' contract it carries — building the per-doc
+  deletion trail the dissolution decision will later check at a Design Review.
+- **Executable where cheap.** The duplicate-IDs tracer is the template; where a behavior's
+  verify loop is genuinely cheap, the spec may earn `has-verifier` via `gwt-vocabulary` →
+  `example` child → generated contract → `bindExample` test with a test anchor. The
+  *systematic* tests-to-executable-specs rewrite remains out of scope.
+
+## 4. The content-routing rubric (binding authoring guidance for every tranche)
+
+The owner's hard constraint for this phase: **a decision spec carries only durable law — content
+that is very expensive to change — and zero procedural or execution context.** This is authoring
+discipline enforced at review gates; it is **never a validator** (checks police conformance and
+honesty, never content-quality — the permanent guardrail stands).
+
+| Content | Home |
+|---|---|
+| A durable ruling itself: the law, non-obvious rejected alternatives, non-obvious consequences | `decision`-kind spec |
+| A ruling that is *only* terminology (a term, its definition, its avoid-list) | `CONTEXT.md` (the ratified glossary) — no decision spec |
+| Design intent not yet implemented | ordinary `Spec` of the honest kind and readiness |
+| Behavior already implemented and worth verifying | spec + precise anchors; the executable loop (contract + bound test) where the loop is cheap |
+| Procedural/execution context: dates, commit SHAs, session/slice/todo numbers, status stamps, review provenance, "landed at …" | **never in a spec** — git history and the plan done-records already carry it |
+
+Litmus tests for the fold author:
+
+1. **The rewrite test** — would the sentence still be true and load-bearing if the repo were
+   re-implemented from scratch tomorrow under the same design? If not, it is execution context.
+2. **The three-part test** (already ratified in the registry): hard to reverse · surprising
+   without context · a real trade-off. All three, or it is not a decision spec.
+3. **Leanness** — the decision slots (context · decision · rationale · consequence) run 1–3
+   sentences each unless rejected alternatives or consequences genuinely earn more (plan 17's
+   standing style directive). The two born decision specs are the size template.
+4. **Current law only** — a decision spec states the law as it stands; amendment history lives
+   in git, not in the spec body.
+5. **Plain language leads** — meaning first, codes parenthetical and only where cross-referencing
+   needs them (the plain-language references decision).
+
+**Decisions in flight** (the pending-decision pattern — already ruled by the open-questions home
+(MD-9) and the typing law (MD-11); this clause applies it, never re-decides it): a durable
+question not yet ruled becomes a `decision`-kind spec at honest low readiness — raised →
+explored → written → ratified is the decision-kind gloss on `idea → scoped → defined → ready` —
+with the unresolved branch as a blocking entry in `intent.openQuestions`; the floor makes a
+blocking question and stated `defined` mutually exclusive, so "pending" is machine-enforced,
+never a label. A question not yet durable stays a plan record. A partially ruled decision splits
+by refinement when the settled core must be consumable now: parent at `defined`+ carrying the
+ruled law, a child at `idea`/`scoped` (`refines` parent) carrying the open branch. Replacement is
+always the `supersedes` relation — "superseded" is a graph query, never an authored status — and
+**no status vocabulary, ever** (`decision.status` is rejected vocabulary; ADR status frontmatter
+must not leak in). Rejected paths are not truth-specs; they live in the winning decision's
+alternatives/consequences.
+
+External soft guidance (calibration, not authority — the repo's own ratified rules win on any
+conflict): `~/.agents/skills/grill-with-docs/ADR-FORMAT.md` (the minimal-ADR shape and the
+what-qualifies list — read broadly, **not** limited to architectural decisions) and
+`~/.agents/skills/grill-with-docs/CONTEXT-FORMAT.md` (tight, opinionated glossary entries).
+
+## 5. Constraints and invariants that bind the plan
+
+- **One canonical surface per ID, no mixing** — the carrier ruling's surviving law; the
+  migration must never leave a blessed commit with a dual-authored ID.
+- **Checks police conformance and honesty, never content-quality and never workflow**; and we
+  claim "deterministically validated," never "provably correct."
+- **Delivery facts are derived, never authored**; the claim taxonomy is never collapsed;
+  readiness is stated only where the floor clears — the corpus stays floor-honest at every
+  intermediate commit the gate blesses.
+- **Intended truth vs realization**: a disagreement found during the fold or expansion is drift
+  to resolve deliberately — never silent promotion of code behavior into intent.
+- **The dual-authority window has a precedence rule**: while concept docs still restate laws
+  the fold has carried into decision specs, the specs are authoritative for settled law and
+  concept prose is exposition — a conflict is drift repaired toward the specs (or the prose
+  marked expository), never resolved by silently promoting code behavior into either surface.
+  The dissolution decision governs when the prose side may shrink.
+- **Ratified terminology end-to-end** — the effort is *self-hosting* (never "dogfooding"); new
+  terms are flagged, not silently invented.
+- **Tracer-bullet discipline** — if a migrated or newly authored spec cannot be expressed
+  cleanly, fix the carrier or the emitter, never the spec.
+- **Rulings under fire are recorded when made** — in the plan's running log and the corpus
+  specs; only rulings passing the three-part test also enter the lean registry.
+- **Git hygiene** — no `git stash`; commit early on the effort branch; commit/push only when the
+  owner asks.
+
+## 6. Owner rulings — the open questions, grilled and resolved (2026-07-18)
+
+These began as open questions; a grill session with the owner resolved all eight before
+Prometheus planning. The detailed plan inherits them as **settled input** — re-litigating any of
+them requires an explicit owner gate. Rulings that pass the three-part test enter the fold as
+decision specs when their tranche lands; until then this brief is their record.
+
+1. **The decision-spec namespace** — **RESOLVED (owner, this brief): `spec:decisions.*`.** The
+   born form is ratified: two segments like every corpus spec, the `specs/decisions/` subdir
+   mirrors the domain layout, and the reserved three-segment form would collide with the
+   dotted-lineage convention (`spec:validation.duplicate-ids.dual-carrier` = child). The
+   registry's "Future spec id" column is amended at fold start; no re-ID, no reference churn.
+2. **`sdp import`'s standing** — **RESOLVED (owner, this brief): durable product verb.**
+   `sdp import` joins the CLI surface permanently — TS carrier → `.sdp.md`, refusal-honest like
+   the parser (findings, never throws). Grounded in the carrier ruling's own wording (the TS DSL
+   is an "import source + per-ID option" — a standing role implies a standing surface); the
+   second-caller bar is met by ratified implication (the checkout migration now; every future
+   per-ID TS→MD flip after). `spec:carrier.sdp-import` may mature toward `ready` with a real
+   verifier as the floor honestly clears.
+3. **Sequencing inside tranche 1** — **RESOLVED (owner, this brief): emitter → migration →
+   hardening → flip.** The checkout migration runs on the corpus-scoped parser and forces
+   grammar growth under fire (table sugar expected); the parity baseline lands against the
+   *settled* post-migration grammar (never paid twice); the canonical-default flip and its
+   operative-record gate close the tranche — the default never points at a surface that has not
+   earned its hardening claim.
+4. **The pack question** — **RESOLVED (owner, this brief): the watch item stands.** Both pack
+   manifests lawfully remain `.pack.sdp.ts` — the one-canonical-surface law is per-ID and the
+   `Pack` is not a kind, so the carrier ruling ("Markdown, all eight kinds") never covered it.
+   Markdown pack syntax is ruled only when a real need forces it; the
+   TS-toolchain-for-pack-authoring wart is named in the docket, not speculatively fixed.
+5. **Fold relation targets** — **RESOLVED (owner, this brief): refine the ruled domain; the
+   corpus wave precedes the fold.** Each fold decision `refines` the most-specific subsystem
+   spec it rules; specs it shapes author `decidedBy` back-edges; `spec:protocol.self-hosting`
+   remains the fallback parent only for genuinely phase-level decisions. **Corollary — execution
+   order is tranche 1 → tranche 3 (first wave) → tranche 2:** the subsystem parent specs must
+   exist before the fold authors its refine targets. The order is a **targets-exist condition,
+   never a full-tranche barrier** — the fold starts once the refine-target minimum (core model
+   · validation · a consumers parent) exists, and remaining tranche-3 waves may continue
+   alongside or after it. The two born specs may be re-pointed at the fold if a more specific
+   parent then exists (a relation edit, not an ID change).
+6. **The diary's residue** — **RESOLVED (owner, this brief), three parts.** (a) *Bodies*: once a
+   durable row's law is distilled into its decision spec, the body leaves the working file —
+   git history is the archive of record; the lean registry keeps name · one-line gloss · spec
+   pointer. (b) *D1–D6*: honor the table's own KEEP note — D3 (Pack reified), D5 (the agent
+   surface scripts the graph), and D6 (the MCP-deferred no) join the fold as decision specs;
+   D1/D2/D4 are carried by tranche-3 subsystem specs; the table survives in the lean registry
+   until the artifacts citing `(Dn)` dissolve. (c) *Measured evidence*: per-figure disposition
+   in the fold ledger — each figure moves into the spec that carries its generalized claim as
+   that spec lands in tranche 3; the section shrinks row-by-row and retires when empty.
+7. **Tranche 3 sizing** — **RESOLVED (owner, this brief): all four subsystem waves ride
+   phase 2** — the core model (`02`), extraction and the one graph (`03`), validation (`05`),
+   and consumers (`06`). Waves run sequentially and owner-gated (one subsystem at a time as
+   working pace, not as phase scope); OmO execution capacity is not the constraint (phase 1's
+   four sessions landed in one). The fold's refine-target minimum (core model + validation +
+   a consumers parent) rides the earliest waves so tranche 2 is never blocked. The phase-3
+   remainder shrinks to the systematic tests-to-executable-specs rewrite and per-doc deletion.
+8. **Post-flip debt intake** — **RESOLVED (owner, this brief): adopt by cluster.** The
+   grammar-hardening cluster (YAML scalar spellings · line-number polish · the `...` closer ·
+   cap-flood behavior · heading/GWT strictness · duplicate-`When` · reifier catch-all totality)
+   rides the parity baseline; the exclude/CLI cluster (Windows absolutes · `--exclude --foo`
+   diagnostics · matcher regression coverage · library-seam wording) rides tranche 1; the
+   Design Review cluster (dynamic-key ordering · the escaping-outside-prose-slots policy) is
+   ruled at migration/flip, when the TS-carrier question narrows; the records cluster (stale
+   provenance wording · plan-16 evidence dispositions · the carrier-truth comment) rides the
+   fold. Only the no-reparse spy seam and temporal token assembly stay deferred — polish with
+   no phase-2 surface.
+
+## 7. Acceptance criteria (the plan must make these checkable)
+
+1. **The flip is total and recorded**: no TS-canonical **product spec ID** remains under the
+   gate's blessed roots — pack manifests lawfully stay TS (§6), the dual-carrier **test
+   fixtures** keep both surfaces by design, and the TS DSL itself is not retired (import source
+   + per-ID option, per the carrier ruling); MD-18's transition clause is discharged across all
+   operative surfaces in step; the pinned consistency scripts are retired/re-pointed; the
+   anti-misleading pass leaves no active interim-rule claim.
+2. **Round-trip fidelity is proven**: import → extract → graph equality for every migrated
+   checkout ID under the **pre-declared delta catalog**, which lands in the done-record (never
+   an ad-hoc test ignore); `npm run check` green on the full clean-clone sequence, plus the
+   installed-package proof for any changed public surface. The authoring-surface fidelity bar
+   is judged at the migration's Design Review — a second layer, never collapsed into graph
+   equality.
+3. **The hardening non-claim is resolved** — replaced by a parity claim with pinned evidence or
+   an explicit, recorded, narrower non-claim — and the chosen claim text lands on the parser
+   specs themselves (the phase-1 non-claim discipline).
+4. **The fold is complete by disposition, not by count**: every registry row, D1–D6, and the
+   measured-evidence section carries exactly one recorded disposition, the folded/folds rows
+   verified with named evidence surfaces; every `decision`-kind spec passes the §4 rubric on
+   review; `DECISIONS.md` is the lean registry; the namespace is uniform; no reference anywhere
+   dangles.
+5. **The corpus waves land honest — all four subsystems**: each new spec floor-clears its
+   stated readiness, carries precise anchors where it claims realization, and appears in the
+   coverage ledger with the concept-doc contract it carries; no readiness above floor, no
+   filler kinds.
+6. **Every fired watch item has a recorded ruling**; every unfired one survives as a named watch
+   item — nothing silently resolves. Gate 4's table-sugar expectation is an expectation, never
+   a quota: unfired means the plan records why the corpus never forced it.
+7. **The docket ledger continues**: plan 17's deferred rows are carried forward or dispositioned;
+   the adopted review-06 clusters (§6 debt intake) land with their carrying tranche; the phase
+   closes with an owner-gated Design Review per session and a whole-phase gate.
+8. **`sdp import` is a documented public surface**: the ratified-glossary amendment landed with
+   the operative records; the CLI contract (arguments and output mode, finding IDs, exit codes,
+   refusal-never-throw, help text) is pinned by tests; the installed-package smoke proof covers
+   the new verb.
+
+## 8. Out of scope (named, deliberately)
+
+- **Per-doc concept deletion** (item 5) — gated by the dissolution decision, later phases.
+- **The systematic tests-to-executable-specs rewrite** (item 4) — only opportunistic tracer-
+  pattern instances ride this plan.
+- **The editor-association gap** — owner-ruled: revisit after the flip.
+- **Cosmetic concept-doc repair** beyond the post-flip anti-misleading pass.
+- **New validator content-quality checks** — the rubric of §4 is review discipline, never a
+  check.
+
+## 9. Process expectations for the detailed plan
+
+Mirror plan 17's proven shape: owner-gated progressive sessions, each closed by a Design Review
+over the generated view; a docket ledger updated as sessions close (planned disposition ≠
+execution state); rulings recorded when made with three-part-test dispositions; faithful RED
+evidence before each behavioral step; clean-snapshot and clean-clone proofs for gate-affecting
+changes; an archived adversarial code review with a verified remediation pass before the phase
+closes. Distinguish PLAN-ONLY sections from execution throughout.
+
+Beyond the shape, the plan must **pin what this brief deliberately leaves open**:
+
+- the `sdp import` CLI contract — arguments and output mode, finding IDs, exit codes,
+  refusal-never-throw, help text, and where its documentation lands; its **write semantics** —
+  write-beside-source vs stdout vs dry-run, the deletion policy (whether import ever deletes
+  `.sdp.ts`, or deletion is the migration's own step), multi-file atomicity (no green gate
+  mid-series with a dual-authored ID), and import-local vs extract-time findings; and the
+  **library seam** — whether a programmatic import surface joins the public barrel for agents;
+- the emitter architecture — source adapters (phase 2: the TS reifier only —
+  `reifyTypeScriptCarrier` over `ReifiedSpec`, `src/extract/reify.ts` + `carrier.ts`) feeding
+  one document emitter in the winning carrier (the glossary's own design), strictly one-way,
+  never a second validation path (the one-validation-path law, MD-14); the **authored-IR
+  boundary** — the emitter consumes the reified authored form, never graph nodes (the graph is
+  derived; prose ownership and heading structure are authored-side facts); and the module's
+  **home** — import is a write path, so its boundary against `src/extract/` is ruled, not
+  defaulted;
+- the checkout grammar matrix (§3 tranche 1) — inventoried before any syntax ruling is
+  scheduled **and before emitter design begins** (the emitter targets the post-gap grammar,
+  never the phase-1 subset); seed cells are already visible: the parent `exampleSpace` on
+  `spec:orders.create-order`, multi-relation envelopes, the frozen grammar's one-entry
+  constraint form;
+- the round-trip delta catalog and its comparison strategy (normalize `file`, or serialize
+  without it);
+- the **two-layer fidelity contract** — graph equality under the delta catalog as the semantic
+  gate, plus the authoring-surface bar (idiomatic Markdown under the ruled grammar and prose
+  ownership), judged at Design Review with fixture evidence;
+- the **canonical-surface disposition** — either file-existence-only stands for phase 2 and
+  `04` §1's config-plus-generated-view claim is repaired to aspirational wording, or a minimal
+  mechanism ships as an explicit deliverable — ruled on the record either way;
+- the consistency-script sweep — the exact pinned strings in `check-carrier-interim.mjs`,
+  `check-carrier-truth.mjs`, and `check-self-hosting-gates.mjs`, each replaced by a post-flip
+  truth pin where a standing docs-agree check is still needed, never lost by blanket
+  retirement;
+- the pack growth process — every new corpus ID enters `specs/self-hosting.pack.sdp.ts` in the
+  same change, and the pack `framing` sheds its phase-1 wording;
+- the fold-ledger and measured-evidence ledger templates;
+- the **per-wave modeling policy** for tranche 3 — altitude policy, kind policy (when a
+  validator is a `rule` vs a behavior detail; when a relation law is a decision vs a model
+  fact), anchor density (which entrypoints earn `implemented`; no decorative anchors), the
+  executable bar (only where the verify loop is cheap), and the coverage-ledger columns
+  (concept path → spec id → readiness → anchor/verifier status) — the waves must produce a
+  typed, impactable delivery model of the engine, never `docs/concept` in frontmatter form;
+- the **hardening-matrix skeleton before session work starts** — the reference set is the TS
+  reifier's refusal classes that matter for authored fidelity (never every `ts-morph`
+  diagnostic), each class mapped to a same-class finding or an explicit named non-claim, with
+  checkout-forced cells added as ruled;
+- a concrete decision prompt for the Design Review escaping / dynamic-key debt at
+  migration/flip — never "polish later";
+- the session DAG with owner gates — one viable, non-binding shape: emitter surface → migration
+  under fire → hardening → flip → corpus waves → fold → close, with the §6 debt clusters
+  slotted per tranche — and **tranche 1's close is a hard phase-internal owner gate**: corpus
+  waves start only after the flip's acceptance criteria (1–3, 8) are green, so expansion
+  pressure never recreates the three-state carrier world;
+- the adversarial code review scheduled before the whole-phase close (the phase-1 F-wave
+  pattern).

+# Plan 18 — Self-hosting phase 2: carrier flip, decision fold, and corpus growth
+
+> **Status:** ✅ EXECUTED — phase-2 implementation complete; final audit passed. This is plan 18, the latest ✅ EXECUTED ground. Build state lives in **`plans/`** — read the highest **primary-numbered** plan's status header, plus any **active subplans it (or its parent family) explicitly designates as current**; ignore unnumbered files and letter-suffixed plans only when no primary/active plan designates them. If that plan is DRAFTED, also read the latest ✅ EXECUTED plan for settled ground.
+>
+> **Spec anchors:** [the phase-2 brief](18-self-hosting-phase-2-brief.md) · [plan 17](17-self-hosting-v1.md) · [the carrier ruling (MD-18)](../docs/concept/DECISIONS.md).
+
+## (a) Status
+
+This is the executable phase plan for the owner mandate recorded at plan 17 Gate 4. It is a
+plan record, not graph content. Execution happens only on
+`feature/protocol-self-application-phase-2`, never on `main`; each session closes with an owner
+Design Review over the generated view.
+
+## (b) Context
+
+Phase 1 landed the Markdown parser, the first self-hosting corpus, and the phase-1 gates. The
+interim carrier rule still permits three states: Markdown-canonical new IDs, TS-canonical
+pre-existing IDs, and the TS checkout tracer. Phase 2 ends that interim rule in the ruled order
+emitter -> checkout migration -> hardening baseline -> flip; it then grows the carrier-stable
+corpus and folds durable decisions into `decision` Specs. The permanent constraints remain: one
+canonical surface per ID, no mixing; delivery facts are derived; and checks enforce conformance
+and honesty, not content quality or workflow.
+
+## (c) Scope
+
+1. **Tranche 1:** land `sdp import` as a refusal-honest TS-to-Markdown product verb, migrate all
+   eleven checkout Specs in one atomic migration series, settle the bounded hardening baseline,
+   then perform the operative-record flip.
+2. **Tranche 2:** fold durable decision laws using the `spec:decisions.*` namespace and a
+   relation-target map whose targets exist before each decision is authored.
+3. **Tranche 3:** model core model, extraction/one graph, validation, and consumers in sequential,
+   owner-gated waves. The fold may start after its target minimum exists; it is not a full-wave
+   barrier.
+
+Out of scope: per-document concept deletion, a systematic tests-to-executable-specs rewrite, the
+editor-association gap, cosmetic repair outside the post-flip anti-misleading pass, and new
+content-quality validators.
+
+## (d) §1 Tranche-1 engineering rulings
+
+1. **Import boundary.** `sdp import` consumes the reified authored form from the TS adapter and
+   emits one Markdown document in the winning carrier. It is one-way and creates no second
+   validation path. Its CLI contract, refusal findings, exit codes, write mode, deletion policy,
+   and package-barrel disposition are ruled before implementation.
+2. **Grammar before emitter.** The checkout grammar matrix in §2 is reviewed before emitter design.
+   A matrix gap is either a recorded under-fire ruling or an explicit non-claim, never an emitter
+   workaround or silent grammar expansion.
+3. **Fidelity.** Semantic fidelity is graph equality under §7's pre-declared delta catalog. The
+   authoring-surface fidelity bar is separate: emitted Markdown must be idiomatic under the ruled
+   grammar and prose-ownership law at Design Review.
+4. **Migration atom.** Each migrated checkout ID deletes its `.sdp.ts` carrier in the same change
+   that adds its `.sdp.md` carrier. The pack manifest may remain TS while the Pack watch item is
+   unfired. No green commit contains a dual-authored checkout ID.
+5. **Hardening claim.** The parser's phase-1 refusal-parity non-claim resolves only after the
+   bounded §3 matrix has evidence: either a like-for-like claim or a narrower named non-claim is
+   recorded on the parser Specs.
+6. **Flip atom.** The carrier ruling (MD-18), `CONTEXT.md`, `AGENTS.md`, relevant truth pins, and
+   the post-flip anti-misleading inventory move together. The TS DSL survives as import source and
+   lawful per-ID option; this phase invents no canonical-surface config unless a recorded ruling
+   makes it an explicit deliverable.
+
+## (e) §2 Checkout grammar matrix
+
+This appendix is the migration inventory, seeded from the eleven real checkout Specs. `confirmed`
+means the frozen plan-17b owner map accepts the row today; it is not a parity claim. No cell is
+marked unconfirmed until a concrete source inspection identifies a gap.
+
+| Checkout ID | Kind | Carrier section(s) required by the TS source | 17b support | Migration note |
+|---|---|---|---|---|
+| `spec:orders.order-management` | behavior | Intent; Behavior; relation envelope | confirmed — 17b rows 128, 138, and 139 cover its `decidedBy` envelope, Intent fields, and rules | confirmed — `order-management.sdp.ts:4-19` is epic/defined behavior with Intent and rules |
+| `spec:orders.create-order` | behavior | Intent; Example space; multi-relation envelope | confirmed — 17b rows 128, 138, and 143 cover ordered `refines`/`constrainedBy`/`decidedBy`, Intent, and `gwt-vocabulary` | confirmed — `create-order.sdp.ts:10-44` is feature/defined behavior; parent `exampleSpace` uses the ruled vocabulary fence |
+| `spec:orders.create-order.valid-cart` | example | Intent; immediate `gwt`; Verification | confirmed — 17b rows 128, 138, 144, and 149 cover relation envelope, Intent, immediate example fence, and executable Verification | confirmed — `create-order-valid-cart.sdp.ts:4-45` is story/ready with the bound happy-path point |
+| `spec:orders.create-order.invalid-cart` | example | Intent; immediate `gwt`; Verification | confirmed — 17b rows 128, 138, 144, and 149 cover relation envelope, Intent, immediate example fence, and executable Verification | confirmed — `create-order-invalid-cart.sdp.ts:4-35` is story/defined; its partial bound point is lawful |
+| `spec:orders.create-order.api-contract` | contract | Intent with blocking open question | confirmed — 17b rows 128 and 138 cover its `refines` envelope, Intent, and blocking Open question | confirmed — `create-order-api-contract.sdp.ts:4-22` is story/idea and uses no contract body |
+| `spec:orders.order-total-rule` | rule | Intent; Rule | confirmed — 17b rows 128, 138, and 140 cover `refines`, Intent, and plain rule entries | confirmed — `order-total-rule.sdp.ts:4-19` is story/defined with two promoted rules |
+| `spec:orders.order-inventory-rule` | rule | Intent; Rule | confirmed — 17b rows 128, 138, and 140 cover `refines`, Intent, and plain rule entries | confirmed — `order-inventory-rule.sdp.ts:4-19` is story/defined with two promoted rules |
+| `spec:orders.order-placement-flow` | workflow | Intent; Workflow | confirmed — 17b rows 128, 138, and 141 cover `refines`/`dependsOn`, Intent, and flow entries | confirmed — `order-placement-flow.sdp.ts:4-25` is feature/scoped with flow-only evidence |
+| `spec:orders.order-latency-constraint` | constraint | Intent; Constraints | confirmed — 17b rows 128, 138, and 145 cover `refines`, Intent, and the one-entry Constraints form | confirmed — `order-latency-constraint.sdp.ts:4-20` is story/defined with one constraint; no multi-entry claim |
+| `spec:orders.order-model` | model | Intent; Model | confirmed — 17b rows 128, 138, and 146 cover `refines`, Intent, and repeated term definitions | confirmed — `order-model.sdp.ts:4-22` is story/defined with five domain terms |
+| `spec:decisions.order-lifecycle` | decision | Intent; Decision | confirmed — 17b rows 128, 138, and 148 cover `refines`, Intent, decision, rationale, and consequences | confirmed — `order-lifecycle.sdp.ts:4-22` is feature/defined with one decision and its consequences |
+
+**Matrix review rule.** A kind-by-section cell becomes `unconfirmed` only with the exact checkout
+ID, source shape, and frozen-grammar mismatch named. The table-sugar watch item remains unfired
+unless this real corpus forces a multi-point authoring surface.
+
+## (f) §3 Hardening matrix
+
+This is the bounded refusal-comparison skeleton. The TS class is the complete
+`extractFindingIds` set in `src/extract/reify.ts`; the Markdown column names the closest current
+finding family, not a claim of one-for-one diagnostic parity. Evidence links are filled when the
+hardening session supplies a fixture and result.
+
+| TS refusal class | Executed Markdown result | Matrix disposition | Checkout-forced cell | Evidence link |
+|---|---|---|---|---|
+| `extract/parse-error` | `extract/invalid-frontmatter` | named non-claim — YAML/frontmatter parsing has no TypeScript parser-diagnostic analogue | confirmed — no checkout source forces malformed syntax | [task-19 matrix](../.omo/evidence/self-hosting-phase-2/task-19-self-hosting-phase-2.matrix.md) · [RED](../.omo/evidence/self-hosting-phase-2/task-19-self-hosting-phase-2.red.log) |

+| `extract/unrecognized-statement` | `extract/invalid-markdown-structure` | named non-claim — Markdown owns prose and structures, not TypeScript statement recognition | confirmed — checkout's rules, flows, lists, and fences are all ruled forms | [task-19 matrix](../.omo/evidence/self-hosting-phase-2/task-19-self-hosting-phase-2.matrix.md) |
+| `extract/unrecognized-property` | `extract/unrecognized-property` | same-class finding | confirmed — all envelope keys and section fields are recognized | [task-19 matrix](../.omo/evidence/self-hosting-phase-2/task-19-self-hosting-phase-2.matrix.md) |
+| `extract/misplaced-authoring` | `extract/invalid-markdown-structure` | named non-claim — Markdown has no executable authoring-call surface; equivalent placement is document structure | confirmed — both example Specs force immediate `gwt` placement after Intent | [task-19 matrix](../.omo/evidence/self-hosting-phase-2/task-19-self-hosting-phase-2.matrix.md) |
+
+## (g) §4 Tranche-2 fold design
+
+The fold distils durable law, not diary chronology. Every row receives one disposition in the
+fold ledger; execution context remains in this plan and git. A new decision refines its most
+specific available target and shaped Specs author `decidedBy` back-edges. The following 19-row map
+is the refine-target template; `target to create` means tranche 3 must create the parent before
+the fold row can land.
+
+| Fold source | Ratified law / carrying item | Refine target | Target status | Intended disposition |
+|---|---|---|---|---|
+| MD-1 | executable meta-model | `spec:protocol.self-hosting` | phase-level | decision spec |
+| MD-2 | adopt the nouns, reject the gates | `spec:protocol.self-hosting` | phase-level | decision spec |
+| MD-4 | one primitive, named coordinates | `spec:model.core-model` | S5 | decision spec |
+| MD-5 | protocol naming | `spec:protocol.self-hosting` | phase-level | decision spec |
+| MD-7 | binding, never liveness | `spec:model.anchors` | S5 | decision spec |
+| MD-10 | content-only sections | `spec:model.spec-sections` | S5 | decision spec |

+| D6 | MCP-deferred no | `spec:consumers.projections-model` | S5 | decision spec |
+
+### Fold-target verification (todo 27)
+
+The 19-row refine-target map is ready for the fold: every immediate target exists after wave 1,
+and MD-20 alone waits for its explicitly scheduled S7 target. No row falls back to the phase-level
+parent merely because a more specific target is deferred.
+
+| Fold source | Ratified law / carrying item | Refine target | Target status | Intended disposition |
+|---|---|---|---|---|
+| MD-1 | executable meta-model | `spec:protocol.self-hosting` | exists — phase-level | decision spec |

+## (h) §5 Tranche-3 wave design
+
+Waves execute in this order: core model (`02`), extraction and the one graph (`03`), validation
+(`05`), then consumers (`06`). Each wave creates only Specs with real typed content: altitude is
+chosen by the actual scope, validators are `rule` Specs only when their law needs independent
+identity, relation laws are decisions only when they pass the durable-ruling rubric, and anchors
+appear only on entrypoints that honestly claim realization. An executable example is added only
+where the verification loop is cheap.

+## (i) §6 Watch items and under-fire rulings
+
+| Watch item | Trigger | Ruling rule | Current state |
+|---|---|---|---|
+| table-sugar syntax | checkout migration needs multi-point authoring | record syntax; preserve MD-17 static sibling expansion | watch — unfired: checkout models multi-case as sibling `example` Specs, not tables. |
+| single-literal vocabulary form | emitted vocabulary cannot express a real slot cleanly | rule only with a concrete fixture | watch — unfired: emitted vocabulary was idiomatic and no concrete slot needed a single-literal form. |
+| multi-entry constraint form | a real migrated constraint requires more than one entry | rule carrier syntax and parity evidence together | watch — unfired: the migrated constraint uses the one-entry form and no real constraint needed more than one entry. |
+| array-section prose sub-owner | prose ownership becomes ambiguous in an array section | record owner and rejection boundary | watch — unfired: no ambiguous prose-ownership case appeared in the migrated sections. |
+| Markdown Pack syntax | a Pack needs Markdown authoring for a real caller | rule separately; Pack is not a kind | watch — unfired: no Pack caller forced Markdown authoring; Pack remains a TS manifest. |
+
+Under fire, a ruling records the trigger, alternatives, outcome, three-part-test disposition, carrying
+Spec, and applicable matrix/ledger cells. Unfired items remain named here at phase close.
+
+### Session 2 rulings under fire
+
+| Trigger | Alternatives considered | Owner outcome | Three-part-test disposition | Carrying Spec / ledger cells |
+|---|---|---|---|---|
+| Design Review dynamic-key ordering followed insertion order and escaping stopped at narrative/description prose slots (review-06) | (1) escape every rendered field uniformly and sort dynamic keys lexicographically at render; (2) escape prose slots only and sort keys; (3) accept trusted-authored rendering and change nothing | **Option 1 ruled.** Every rendered field uses one escaping policy, including titles, rules, terms, criteria, open-bag keys/values, and other authored labels; model/open-bag dynamic keys sort lexicographically at render time. Permuted graph insertion orders now render byte-identically. Ordering and escaping are the only output changes; information content is preserved. | Not admitted as a durable decision Spec: this is a mechanically reversible projection representation fix, so it fails the hard-to-reverse part of the three-part test. The regression suite is the execution record. | Planned carrier: `spec:consumers.design-review` (S5). §8 rows “Design Review dynamic-key ordering”, “Design Review escaping outside prose slots”, and “Design Review cluster” are `done s2`. |
+
+No other todo 13 to 15 activity triggered an under-fire ruling: the checkout migration and README
+walkthrough used the ruled grammar without a forced gap.
+
+### Session 3 rulings under fire
+
+| Trigger | Alternatives considered | Owner outcome | Three-part-test disposition | Carrying Spec / ledger cells |
+|---|---|---|---|---|
+| YAML accepted an exact `...` document-end marker before the carrier's later exact `---` closer | (1) accept YAML's document-end token inside the envelope; (2) reject it and retain the frozen one-closer carrier grammar | **Option 2 ruled.** An exact `...` line anywhere before the required closing `---` refuses. The carrier has one envelope closer and never embeds a second YAML document boundary. | Not admitted as a durable decision Spec: this restores the already-frozen 17b grammar and is mechanically reversible, so it fails the surprising-new-trade-off part of the three-part test. | `spec:carrier.envelope-contract`; §8 “Frontmatter `...` document end”. |
+| Depth and node breaches consumed the 100-finding budget with repeated identical diagnostics | (1) report every offending descendant; (2) stop traversal at the first breach; (3) emit one summary per breached limit per document while continuing traversal for independent findings | **Option 3 ruled.** Depth and node limits each emit at most one finding per document; traversal continues so unrelated authored-fidelity findings remain visible. | Not admitted as a durable decision Spec: this is a bounded diagnostic policy, not a hard-to-reverse domain law. | `spec:carrier.envelope-contract`; §8 “Depth and node cap finding flood”. |
+| Review-06 exposed body-parser drift from the frozen trim and immediate-placement rules | (1) retain permissive fence placement and closing-marker interpretation; (2) restore the frozen behavior | **Option 2 ruled.** An example `gwt` fence is the final nonblank Intent block; trailing ASCII whitespace is trimmed from `### Open questions`; terminal `#` characters are literal heading text, with H2 text still passing through owner recognition. | Not admitted as a durable decision Spec: these are repairs to the frozen 17b representation, not new durable trade-offs. | `spec:carrier.markdown-parser`; §8 GWT and heading rows. |
+
+### Session 3 hardening-claim disposition
+
+**Option (a) ruled.** The executed §3 matrix contains only six same-class findings and four named
+non-claims, so `spec:carrier.markdown-parser` carries a like-for-like bounded refusal-parity claim
+backed by `test/extract-parity.test.ts` and the task-19 matrix evidence. It does not claim full
+parity. The named non-claims remain explicit:
+
+1. `extract/parse-error` — YAML/frontmatter parsing has no TypeScript parser-diagnostic analogue.
+2. `extract/non-static-section` — TypeScript degrades optional section properties; Markdown refuses malformed documents whole.
+3. `extract/unrecognized-statement` — Markdown owns prose and structures, not TypeScript statement recognition.
+4. `extract/misplaced-authoring` — Markdown has no executable authoring-call surface.
+
+## (j) §7 Done-record and delta catalog
+
+The done-record is process evidence, never graph content. A session appends its commit SHA,
+Design Review outcome, corrections, fired rulings, matrix evidence, and any scope delta. The
+round-trip catalog is declared before implementation and may change only by an explicit ruling.
+
+| Delta | Comparison treatment | Why lawful | Evidence state |
+|---|---|---|---|
+| `.sdp.ts` to `.sdp.md` file suffix | normalize `file` path before graph comparison | physical carrier path is not semantic intent | done — migration round-trip evidence confirms normalized graph equality |
+| physical Markdown envelope syntax | compare reified authored content, not formatting tokens | envelope representation differs lawfully | done — migration round-trip evidence confirms reified authored equality |
+| TS source comments | omit from graph comparison | comments are not graph content | done — migration round-trip evidence confirms comments do not affect the graph |
+| delivery facts under the same anchor set | compare after both sides use identical anchors | facts remain derived from bindings | done — migration round-trip evidence confirms identical recomputed facts |
+
+### Whole-phase done-record
+
+- **Executed delta catalog:** the importer preserves authored `ReifiedSpec.data` with zero prose normalization. The graph comparison normalizes only the carrier file suffix from `.sdp.ts` to `.sdp.md`; physical envelopes and TypeScript source comments remain outside graph content; delivery facts are recomputed under the same anchor set; and `schemaVersion` remains unchanged. The semantic equality gate and the emitted-Markdown authoring-surface review both passed.
+- **Executed delivery:** `sdp import` landed as the durable, fs-free import seam with the CLI write-beside and `--dry-run` boundary; all eleven checkout Specs migrated atomically to Markdown; the canonical-default carrier rule replaced the interim rule; the bounded parser refusal-parity claim, decision-spec fold, and four honest corpus waves landed. The resulting self-hosting graph holds 58 Specs, 1 Pack, and 36 anchors, with 7 `ready` and 51 `defined` Specs.
+- **Session SHA summary:** G1 is `f06f14d`; G2 is `df444f2`; G3 is `0bb200a`; G4, G5, G6, and G8 are consolidated at `67cfda7` under the continuation directive; G7 remains `b471189034e1ee238394f3364c349937be6bebed` because its corpus and fold-completion evidence was accepted independently before the whole-phase close.
+- **Watch items:** all five terminal states are unfired. Table sugar was not forced because waves used existing sibling Specs and ruled body forms. The single-literal vocabulary form was unnecessary beyond the ruled literal syntax. No wave required a multi-entry constraint. New prose stayed under existing typed section owners, leaving the array-section sub-owner unfired. The Pack remains a TypeScript manifest, with no caller requiring Markdown Pack authoring.
+- **Docket close:** the twelfth preflight leg and decision-spec namespace divergence are done; the indirect `then` key and the Model term named `description` are verified; and the checkout duplicate-carrier fixture exemption remains an explicit preserved test-fixture exception.
+- **Deferred tail:** no-reparse spy coverage remains deferred because named-import interception is weaker than an injected read seam. Temporal token assembly remains deferred because the sanctioned temporal-guard pattern still applies; its comment can be narrowed later.
+- **Lean registry rulings:** the phase admitted `spec:decisions.*` records for the executable meta-model, naming and one-primitive laws, binding and section ownership, the typing and readiness-floor laws, one validation path, the `.sdp.ts` extension and carrier ruling, prose ownership, point-per-example, and the exclusion and envelope-grammar contracts. The Pack, agent-surface, and deferred-MCP decisions joined them; D1, D2, and D4 remain carried by their ordinary Specs. Each admission passed the three-part durability test and is linked from the lean registry.
+- **Close evidence:** the acceptance assembly, adversarial-review remediation, and clean-clone and installed-package proofs are recorded in [task 40](../.omo/evidence/self-hosting-phase-2/task-40-self-hosting-phase-2.acceptance.md), [task 41](../.omo/evidence/self-hosting-phase-2/task-41-self-hosting-phase-2.review.md), and [task 42](../.omo/evidence/self-hosting-phase-2/task-42-self-hosting-phase-2.final-proofs.log).

+## (k) §8 Docket ledger
+
+Planned disposition is not execution evidence. Every row starts pending and closes as `done`,
+`deferred`, or `dropped` with a reason; the table continues the plan-17 docket format.
+
+| Docket item (origin) | Planned disposition | Execution state |
+|---|---|---|
+| Markdown reifier catch-all totality (review-06) | Adopt with hardening baseline | done s3 — the public Markdown reifier now converts every unexpected throw into one `extract/invalid-frontmatter` finding, mirroring the TS boundary |
+| YAML 1.2 scalar spellings (review-06) | Adopt with grammar hardening | done s3 — plain exponent, hexadecimal, and signed-infinity spellings classify as non-string YAML scalars; quoted scalars remain strings |
+| YAML parser line-number mismatch (review-06) | Adopt with grammar hardening | done s3 — YAML-native diagnostic text and structured `finding.line` now share carrier-relative line numbers |
+| Frontmatter `...` document end (review-06) | Adopt with grammar hardening | done s3 — an exact document-end line before the required `---` closer refuses under the §6 stricter ruling |
+| Non-mapping-root accumulated findings (review-06) | Adopt with grammar hardening | done s3 — mapping-root refusal preserves prior parser, warning, and directive findings before capping |
+| Depth and node cap finding flood (review-06) | Adopt with grammar hardening | done s3 — the §6 bounded policy emits one summary per breached limit per document and preserves traversal |
+| GWT fence placement in Intent (review-06) | Adopt with grammar hardening | done s3 — example `gwt` is terminal within Intent, immediately following the authored Intent block |
+| Heading trailing whitespace and trailing `#` titles (review-06) | Adopt with grammar hardening | done s3 — H3 trailing ASCII whitespace trims; terminal `#` is literal H1/H2 text before owner recognition |
+| Duplicate `When` reporting and dead `mapOwner` branch (review-06) | Adopt with grammar hardening | done s3 — a duplicate `When` emits one finding and the unreachable owner fallback is removed |
+| Windows absolute excludes and `--exclude --foo` diagnostics (review-06) | Adopt with exclude/CLI cluster | done s1 — reject Windows drive-letter absolutes as invalid rather than normalize them, preserving MD-20 root-relative POSIX scope; a flag operand names itself in the CLI usage error |
+| Path-prefix matcher coverage (review-06) | Adopt with exclude/CLI cluster | done s1 — focused regression proves `foo` excludes only `foo` and its slash-delimited descendants, never `foobar` |
+| Library-seam exclusion wording (review-06) | Adopt with exclude/CLI cluster | done s1 — `normalizeExcludes` owns library diagnostics; `parseBuildArgs` translates them into `sdp <cmd>` usage wording |
+| Design Review dynamic-key ordering (review-06) | Rule at migration/flip | done s2 — Option 1 sorts model/open-bag dynamic keys lexicographically at render; shuffled insertion orders produce byte-identical pages |
+| Design Review escaping outside prose slots (review-06) | Rule at migration/flip | done s2 — Option 1 applies one escaping policy to every rendered field, including titles, rules, terms, criteria, labels, and open-bag data |
+| Row-3 enrichment delta (review-06) | Record in delta catalog | done s2: recorded in the migration/delta catalog for G2 close. |
+| Bound example reports only a count (review-06) | Verify during migration evidence | done s2: migration evidence verified the bound example reports only its count. |
+| Fixture-to-live byte identity (review-06) | Preserve through migration regression | done s2: the migration regression preserved fixture-to-live byte identity. |
+| No-reparse spy coverage (review-06) | Carry forward as deferred polish | deferred — named-import interception remains weaker than an injected read seam |
+| Carrier-truth comment and temporal token assembly (review-06) | Records cluster adopts comment; token assembly deferred | done — comment now states only blockquote stripping and whitespace collapse; temporal token assembly remains deferred under the sanctioned temporal-guard pattern |
+| Stale provenance wording and plan-16 evidence dispositions (review-06) | Adopt with records cluster | REPAIRED — approval artifact wording aligns with CONTEXT; plan-16 repair items dispositioned below |
+| Twelfth preflight leg and decision-spec namespace divergence (review-06) | Verify preflight; resolve namespace in fold | done — the recorded preflight chain delta is benign, and the `spec:decisions.*` namespace fold landed |
+| Indirect assembly of the `then` graph key (review-06) | Verify remediation remains intact | verified — phase-1 remediation names the `then` key directly |
+| Model term named `description` (review-06) | Verify remediation remains intact | verified — phase-1 remediation preserves the Model term named `description` |
+| Checkout duplicate-carrier fixture exemption (review-06) | Preserve as explicit fixture exception | preserved as explicit fixture exception — the deliberate dual-carrier fixture remains outside the one-canonical-surface product rule |
+| Exclude/CLI cluster (brief §6) | Land in tranche 1 | done s1 — loud Windows absolute rejection, flag-operand usage diagnostics, segment-boundary coverage, and library/CLI wording separation landed |
+| Grammar-hardening cluster (brief §6) | Land with parity baseline | done s3 — all eight RED→GREEN items landed with focused public-reifier regressions and stable finding IDs |
+| Design Review cluster (brief §6) | Rule at migration/flip | done s2 — owner ruled Option 1; deterministic ordering and uniform escaping landed RED-first with focused projection regressions |
+| Records cluster (brief §6) | Land with decision fold | REPAIRED — lean registry, measured evidence routing, record wording, and audit comment landed |
+| README (plan-16 §6) | Doc-repair disposition | REPAIRED — anti-misleading carrier pass |
+| `00` (plan-16 §6) | Doc-repair disposition | REPAIRED — anti-misleading carrier pass |
+| `01` (plan-16 §6) | Doc-repair disposition | REPAIRED — anti-misleading carrier pass |

+| `07` (plan-16 §6) | Doc-repair disposition | SUPERSEDED — S7 extraction work owns remaining scale evidence |
+| CONTEXT/DECISIONS (plan-16 §6) | Doc-repair disposition | REPAIRED — glossary-consistent approval artifact and lean registry |
+| Table-sugar syntax (watch item) | Rule only if checkout forces it | done s2: unfired, multi-case checkout behavior uses sibling `example` Specs, not tables. |
+| Single-literal vocabulary form (watch item) | Rule only if corpus forces it | done s2: unfired, idiomatic emitted vocabulary required no single-literal slot form. |
+| Multi-entry constraint form (watch item) | Rule only if corpus forces it | done s2: unfired, the migrated constraint uses the ruled one-entry form. |
+| Array-section prose sub-owner (watch item) | Rule only if corpus forces it | done s2: unfired, migrated sections produced no ambiguous prose-ownership case. |
+| Markdown Pack syntax (watch item) | Rule only if a Pack caller forces it | done s2: unfired, no caller forced Markdown Pack authoring; the Pack remains a TS manifest. |
+
+## (l) §9 Commit strategy
+
+1. Keep all work on `feature/protocol-self-application-phase-2`; never use a stash and never
+   commit to `main`.
+2. Land a behavioral change with its direct tests and Spec/anchor changes in the same atomic
+   commit. Order foundations before callers: carrier/emitter seam, CLI surface, migration, parser
+   hardening, operative records, then waves and fold.
+3. The migration may be a tight series, but no commit admitted by `npm run check` may contain both
+   canonical carriers for one checkout ID. Gate-affecting work includes a clean-snapshot and
+   clean-clone proof before owner acceptance.
+
+## (m) §10 Gate ledger G1-G8

+
+## (n) Acceptance criteria and final verification wave
+
+1. The flip is total and recorded: no TS-canonical product Spec remains under the blessed roots;
+   Pack manifests and fixture exemptions are named; post-flip records agree.
+2. Every migrated checkout ID passes graph equality under §7 and the authoring-surface fidelity
+   review. `sdp import` has pinned CLI behavior and installed-package smoke evidence.
+3. The parser hardening non-claim resolves into bounded evidence or a named, narrower non-claim.
+4. Every durable registry row, D1-D6, and measured-evidence item has one fold disposition; new
+   decision Specs pass the durable-law rubric and all references remain resolvable.
+5. All four corpus waves carry honest readiness, precise anchors where realization is claimed, and
+   a §5 coverage-ledger row. No filler kinds or decorative anchors are accepted.
+6. Every fired watch item has a ruling; every unfired item remains named in §6.
+7. The docket is fully dispositioned, each session has an owner Design Review, and the final wave
+   runs the full `npm run check`, clean-snapshot check, clean-clone check, installed-package proof
+   for changed public surfaces, adversarial review, remediation verification, and G8 owner gate.

+# self-hosting-phase-2 - Work Plan
+> **Status:** ✅ EXECUTED — phase-2 implementation complete; final audit passed. This is plan 18, the latest ✅ EXECUTED ground. Build state lives in **`plans/`** — read the highest **primary-numbered** plan's status header, plus any **active subplans it (or its parent family) explicitly designates as current**; ignore unnumbered files and letter-suffixed plans only when no primary/active plan designates them. If that plan is DRAFTED, also read the latest ✅ EXECUTED plan for settled ground.
+
+## TL;DR (For humans)
+
+**What you'll get:** The Protocol's specs all speaking one language — Markdown by default — with a new permanent `sdp import` command that converts old TypeScript specs faithfully, the worked example migrated with machine-proven fidelity, sixteen durable design rulings moved out of a prose diary into typed, checkable decision records, and the project's own delivery model grown from 15 to roughly 60 interlinked, honestly-verified specs across every major subsystem.
+
+**Why this approach:** The importer is built and proven *before* anything is migrated (round-trip equality under a pre-declared rulebook, so fidelity is never redefined mid-flight), and the big default-flip lands as one atomic, gated change — so no commit ever tells two contradictory carrier stories. The fold waits until its target specs exist, so every decision record points at the subsystem it actually rules.
+
+**What it will NOT do:** It will not retire the TypeScript DSL (it survives as an import source and a per-ID option), will not delete any concept document, will not rewrite ordinary tests into executable specs, and will not let any automated check judge content quality — checks police conformance and honesty only.
+
+**Effort:** XL
+**Risk:** Medium - the flip touches every operative record at once; contained by the one-atomic-commit rule, the machine docs-agree checks, and the hard owner gate before any corpus growth.
+**Decisions to sanity-check:** file-existence-only canonical surface (no config mechanism — the stronger concept-doc claim gets repaired to aspirational); the importer never deletes sources (the migration owns deletion, atomically per spec); the decision-diary bodies are deleted once distilled (git history is the archive); table sugar likely stays unfired — the migration is expected to need no new grammar.
+
+Your next move: approve this plan and start work — or ask for a high-accuracy review first. Full execution detail follows below.

+
+> TL;DR (machine): XL effort, Medium risk, phase-2 self-hosting: sdp import emitter + checkout migration + parser hardening + canonical flip + decision fold + corpus waves
+
+## Scope
+
+Commissioning brief: `plans/18-self-hosting-phase-2-brief.md` (owner rulings §6 are settled input; re-litigating any requires an explicit owner gate). Settled ground: `plans/17-self-hosting-v1.md` (✅ EXECUTED). Work happens on branch `feature/protocol-self-application-phase-2` — never on `main`. Owner rulings confirmed this planning round: canonical surface = file-existence-only (repair `04` §1 to aspirational) · import = write-beside + `--dry-run`, never deletes source · pure emit on the package barrel · TDD core / tests-after corpus.
+
+### Must have
+
+- **M1 — the emitter (`src/import/`)**: `emitMarkdownSpec(reified)` pure document emitter honoring the ruled Markdown grammar **as confirmed/grown by the checkout grammar matrix** (the frozen 17b tables are the baseline: envelope subset, heading→section map, `gwt`/`gwt-vocabulary` fences, prose ownership — the emitter targets the post-gap grammar, never the phase-1 subset by assumption); `importTypeScriptSpec(sourceText, relativePath)` pure, fs-free orchestration over `reifyTypeScriptCarrier`; `import/*` finding namespace for verb-local conditions (reifier `extract/*` findings pass through unchanged — finding currency stays single-sourced); refusal-honest, never throws; barrel exports: `emitMarkdownSpec`, `importTypeScriptSpec` (a deliberate pure, fs-free composition — the agent-useful one-call form), `importFindingIds`, and the result types. TDD.
+- **M2 — `sdp import <path...> [--dry-run]`**: durable CLI verb — positional paths are `.sdp.ts` files or roots (roots scan for `*.sdp.ts`); write-beside (`foo.sdp.ts` → `foo.sdp.md`); **never deletes source** (deletion is the migration's own step); refuses overwrite of an existing target (`import/target-exists`); refuses `*.pack.sdp.ts` (`import/pack-unsupported` — packs stay TS by ruling); per-file fail-collecting semantics (every requested file attempted, all findings reported, exit 1 if any error-severity finding or operational error — the verb's atomicity law; the per-ID emit+delete atomicity binds the migration, not the verb); `--dry-run` prints a per-file header + the would-be emitted Markdown to stdout and writes nothing; dedicated arg parser mirroring `parseBuildArgs` diagnostics; `formatFinding` rendering; help-text addition pinned by test. Documentation lands in: the CLI help text, the checkout README (migration session), and the root README's CLI section if one exists (flip-session anti-misleading pass verifies). TDD.
+- **M3 — round-trip proof**: two layers — **authored-level** (reify TS fixture → emit → reify emitted Markdown → `ReifiedSpec.data` deep-equal with zero prose normalization: the emitter reproduces source text the parser re-parses into identical strings; any prose delta is an emitter defect to fix — tracer-bullet discipline — or a recorded ruling, never a shrug) and **graph-level** (`sdp build` on pre/post-migration corpora, normalize under the pre-declared delta catalog, deep-equal nodes+edges+deliveryFacts). **Delta catalog** (pre-declared; grows only by recorded ruling; lands in the migration session's done-record): (1) `file` suffix `.sdp.ts`→`.sdp.md` normalized; (2) physical envelope differences are not graph content; (3) TS source comments are not graph content; (4) delivery facts recomputed under the same anchor set; (5) `schemaVersion` unchanged.
+- **M4 — checkout-v1 migration**: all 11 spec IDs moved to `.sdp.md` via the emitter in **one atomic commit** (every emit + its TS delete together — no blessed commit ever holds both surfaces of an ID); README walkthrough rewritten for the Markdown surface; two-layer fidelity proven — graph equality under the delta catalog (semantic gate) + the authoring-surface bar (idiomatic Markdown under the ruled grammar and prose ownership) judged at the migration's Design Review with the emitted files as the exhibit.
+- **M5 — parser-hardening baseline**: bounded parity matrix — the TS reifier's 10 authored-fidelity refusal classes (`src/extract/reify.ts:53-64`) each mapped to a same-class Markdown finding or an explicit named non-claim, checkout-forced cells added as ruled (skeleton lands in the repo plan before session work; execution against the settled post-migration grammar happens in the hardening session, after the grammar-hardening debt fixes so parity is measured once); the grammar-hardening debt cluster (YAML 1.2 scalar spellings · line-number polish · `...` closer · non-mapping-root accumulated findings · cap-flood · heading/GWT strictness · duplicate `When` + dead `mapOwner` branch · `reifyMarkdownCarrier` catch-all totality — review-06 lines 251–262); the phase-1 non-claim replaced by a parity claim with pinned evidence (the executed matrix) or a revised, explicitly scoped non-claim — claim text lands on the parser specs.
+- **M6 — the canonical-default flip**: one commit (green at the blessed commit, no intermediate claim) — post-flip operative records (MD-18 Decision text discharges the transition clause; `CONTEXT.md` carrier resolved entry rewritten; the `sdp import` term was already amended at todo 7 (the multi-adapter verb — one import verb, many source adapters; the TS adapter landed; the gen-1 `.feature` adapter designed-in and deferred on the record) and is verified + machine-pinned here via the truth-script re-pin; `AGENTS.md` interim sentence replaced) · the post-flip operative sentence: *"Specs default to Markdown; Packs remain TS until a Pack syntax ruling; the TS DSL survives as import source and a lawful per-ID option."* · consistency-script sweep (`check-carrier-interim.mjs` renamed `check-carrier-rule.mjs` with post-flip pins and a full reference sweep — its own header/usage lines, the comment in `check-carrier-truth.mjs:30`, a repo-wide grep for the old filename; `check-carrier-truth.mjs` CLAIMS re-pinned to post-flip wording, the interim sentence added to OBSOLETE, the TS-mention RULES classification audit retained; the Gate-4 phase-2 pins in `check-self-hosting-gates.mjs:187-197` retired/re-pointed — the plan-18 gate ledger itself is scaffolded at todo 1, not here) · the anti-misleading pass (concept `00`/`04`/`07`/README, jtbd stories, the example README already migrated, MD-15's wording re-checked, package docs/root README — inventory seeded from the truth script's audit map) · `04` §1's canonical-surface-config sentence repaired to aspirational wording. Closes in the **hard phase-internal owner gate** (acceptance 1–3 + 8 green before any corpus work).
+- **M7 — corpus expansion** under the per-wave modeling policy (Execution strategy §policy, binding on every authoring todo): wave 1 = refine-target minimum — `spec:model.core-model`, `spec:model.spec-sections`, `spec:model.relations`, `spec:model.stable-ids`, `spec:model.pack-aggregate`, `spec:model.anchors`, `spec:validation.two-check-families`, `spec:consumers.projections-model`, `spec:consumers.agent-surface`, `spec:consumers.design-review`; validation wave — `spec:validation.referential-integrity`, `spec:validation.claim-separation`, `spec:validation.verification-linkage` (bundles verifies-linkage + oracle-linkage), `spec:validation.pack-coherence`, `spec:validation.authored-honesty` (bundles authoring-shape + delivery-facts), `spec:validation.warn-level-signals` (bundles orphans + gaps); consumers remainder — `spec:consumers.reader`, `spec:consumers.edit-model` (+ `spec:consumers.projections-model` enrichment); extraction/graph wave — `spec:extraction.excludes`, `spec:extraction.claim-taxonomy`, `spec:extraction.regenerability`, `spec:extraction.schema-versioning`, `spec:extraction.executable-contracts`, plus in-place enrichment of the phase-1 extraction seeds. Coverage ledger row per spec (concept path → spec id → readiness → anchor/verifier status → disposition note); every new ID enters `specs/self-hosting.pack.sdp.ts` in the same change; pack title/framing shed phase-1 wording; `pack:self-hosting-v1` ID unchanged.
+- **M8 — the decision fold**: registry "Future spec id" column amended to `spec:decisions.*` at fold start; **19 new decision specs** — batch 1 carrier/extraction cluster (MD-14, MD-15, MD-17, MD-18, MD-19, MD-21), batch 2 model/phase cluster (MD-1, MD-2, MD-4, MD-5, MD-7, MD-10, MD-11, MD-12, MD-16), batch 3 (D3, D5, D6), **plus MD-20 landed at the S7 fold-completion** once its refine target `spec:extraction.excludes` exists (targets-exist ordering, never the fallback for a ruled-domain decision). Relation shape per owner §6.5: **each fold decision `refines` the most-specific subsystem spec it rules** (fallback `spec:protocol.self-hosting` only for genuinely phase-level decisions) **and** specs a decision shapes author `decidedBy` back-edges. Pinned refine-target map (→ wave that creates the target): MD-1 → `spec:protocol.self-hosting` (phase-level) · MD-2 → `spec:protocol.self-hosting` (phase-level) · MD-4 → `spec:model.core-model` (S5) · MD-5 → `spec:protocol.self-hosting` (phase-level) · MD-7 → `spec:model.anchors` (S5) · MD-10 → `spec:model.spec-sections` (S5) · MD-11 → `spec:model.spec-sections` (S5) · MD-12 → `spec:validation.readiness-floor` (exists) · MD-14 → `spec:validation.two-check-families` (S5) · MD-15 → `spec:carrier.markdown-authoring` (exists) · MD-16 → `spec:validation.readiness-floor` (exists — the carried-evidence law is implemented in `src/validate/readiness-floor.ts:150-181`; the multi-point remainder — the authoring-shape stand-in and the `doc:`-target deferral — rides as body content/consequences in the fold spec, and a `decidedBy` back-edge keeps the floor law linked, never orphaned) · MD-17 → `spec:model.spec-sections` (S5) · MD-18 → `spec:carrier.markdown-authoring` (exists) · MD-19 → `spec:carrier.prose-ownership-rule` (exists) · MD-20 → `spec:extraction.excludes` (S7) · MD-21 → `spec:carrier.envelope-contract` (exists) · D3 → `spec:model.pack-aggregate` (S5) · D5 → `spec:consumers.agent-surface` (S5) · D6 → `spec:consumers.projections-model` (S5). Each spec authored per the §4 rubric (three-part test · leanness 1–3 sentences per slot · current law only · plain language leads · zero procedural context). Per-row dispositions: D1 → carried by `spec:model.core-model` (verify named surface) · D2 → carried by `spec:model.spec-sections` (verify) · D4 → carried by `spec:consumers.design-review` (verify) · MD-8/MD-9/MD-13 folded/folds — verify the carrying surfaces (`src/model/anchors.ts` doc-comment, `src/model/sections.ts`, the `readiness-floor.ts` header), never re-author. The two born specs' keep-vs-repoint verdicts recorded in the fold ledger (recommendation: keep both at `spec:protocol.self-hosting` — genuinely phase-level; a relation edit only if the owner rules otherwise, never an ID change). Measured evidence: dispositions recorded at the fold (carrier spec + landing wave per figure); figure moves land **with their carrying waves** — `~⅕ tokens` → `spec:consumers.agent-surface` (S5) and `single-digit to ~25%` → `spec:consumers.projections-model` (S5) move at the fold; `< ~50 specs` and `~10k+ nodes` → `spec:extraction.regenerability` (S7) move at the S7 fold-completion; the section shrinks row-by-row and retires when empty. Diary bodies deleted once distilled (git is the archive); `DECISIONS.md` becomes the lean registry (name · one-line gloss · spec pointer · folded/CONTEXT-only dispositions) — the post-flip carrier sentence stays verbatim in the lean registry's MD-18 row (if its wording must change, `check-carrier-rule.mjs` is re-pinned in the same change); the D1–D6 table survives until the artifacts citing `(Dn)` dissolve. Fold ledger records every disposition (process record, never graph content).
+- **M9 — the repo plan**: `plans/18-self-hosting-phase-2.md` (plan-17 shape: status header · context · scope · tranche sections with every engineering ruling · the checkout grammar matrix + the 10-row hardening-matrix skeleton as appendices · sessions S1–S8 · docket ledger seeded from plan 17 §6's deferred rows · fold ledger + measured-evidence ledger + coverage ledger **with actual templates, not just names** · the five named watch items with their disposition states · acceptance criteria 1–8 · gate ledger G1–G8 · PLAN-ONLY sections marked as such), kept in lockstep with execution; `check-self-hosting-gates.mjs` extended at todo 1 with the plan-18 gate-ledger block (G1–G8 definitions, pending-tolerant rows stamped `accepted` + SHA as sessions close — the same mechanism plan 17's ledger used); `AGENTS.md` "what now" pointer updated at land and at close **without touching the interim-pinned AGENTS.md sentence before the flip**.
+- **M10 — debt intake**: review-06 clusters adopted per owner §6.8 — grammar-hardening → M5; exclude/CLI (Windows absolutes · `--exclude --foo` diagnostics · matcher regression coverage · library-seam wording) → the emitter/CLI session; Design Review cluster (dynamic-key ordering · escaping outside prose slots) ruled at migration/flip with a concrete decision prompt (recommendation: escape every rendered field uniformly + lexicographic dynamic-key ordering, with determinism tests — the prompt, options, and trade-offs spelled out in todo 15); records cluster (stale provenance wording at `05`:106 + `CONTEXT.md`:182 · plan-16 evidence dispositions · carrier-truth comment narrowing) → the fold session. No-reparse spy seam + temporal token assembly stay deferred (recorded in the docket).
+- **M11 — phase close**: docket reconciliation (every carried row dispositioned done/deferred/dropped with why — nothing silently dropped) · whole-phase anti-drift audit (floor-honest readiness, no filler specs, all five watch items' states verified, acceptance 1–8 evidence assembled) · adversarial code review archived at `reviews/07-self-hosting-phase-2-code-review.md` with a verified remediation pass · installed-package proof covering `sdp import` + the new barrel exports · clean-clone `npm run check` green.
+- **M12 — `spec:carrier.sdp-import` enriched** from `idea` upward only as the floor honestly clears (target `ready` with a real verifier: `spec:carrier.sdp-import.round-trip` example child → generated contract → bound test with test anchor, the duplicate-IDs tracer pattern; the new ID enters the pack manifest in the same change).
+
+### Must NOT have (guardrails, anti-slop, scope boundaries)
+
+- No dual-authored product spec ID on any blessed commit (one canonical surface per ID, no mixing — pack manifests lawfully stay TS; the dual-carrier test fixtures keep both surfaces by design).
+- `sdp import` is a durable product verb — never a migration script; import never deletes `.sdp.ts` (deletion is the migration's own step); no second validation path (MD-14 — import consumes the reifier, it never re-validates).
+- The TS DSL is not retired (import source + lawful per-ID option); no Markdown `Pack` syntax (watch item stands, unforced); no gen-1 `.feature` adapter implementation (designed-in, deferred on the record); no canonical-surface config mechanism (file-existence-only stands; `04` §1 repaired to aspirational).
+- No table sugar unless the grammar matrix forces it under fire (expectation, never quota — unfired means the done-record says why the corpus never forced it).
+- No per-doc concept deletion; no systematic tests-to-executable-specs rewrite (only opportunistic tracers); no editor-association work; no cosmetic concept-doc repair beyond the anti-misleading pass.
+- Checks police conformance and honesty, never content-quality and never workflow — the §4 rubric is review discipline, never a validator; "deterministically validated," never "provably correct."
+- Delivery facts derived, never authored; the claim taxonomy never collapsed; no readiness above floor; no filler/thin specs; a kind authored only where real content forces it.
+- No status vocabulary on decision specs (`decision.status` rejected; ADR status frontmatter never leaks in); amendment history lives in git, not spec bodies.
+- Determinism stays regenerate-and-compare (`--check-clean`) — never committed goldens.
+- No `git stash`; commit early on the effort branch; commit/push only when the owner asks.
+
+## Verification strategy
+> Zero human intervention - all verification is agent-executed. Owner gates (G1–G8) are the single exception: Atlas prepares the evidence pack, the owner dispositions, Atlas records.
+
+- Test decision: **TDD** (vitest, RED evidence quoted before every behavioral step) for the emitter, CLI verb, round-trip harness, parity matrix, and every debt-cluster fix; **tests-after** for corpus-wave and fold authoring (no behavior to drive — conformance + honesty are enforced by `npm run check`); agent-executed QA everywhere.
+- The green gate: `npm run check` — `package.json:49` (check:temporal → lint → format:check → build → generate:self-hosting → generate:example → typecheck → typecheck:examples → test → check:self-hosting → check:example → preflight). Green at every blessed commit; full clean-clone run for gate-affecting changes.
+- Evidence: `.omo/evidence/self-hosting-phase-2/task-<N>-self-hosting-phase-2.<ext>` (outside ulw-loop). Every QA scenario writes its artifact there.
+
+## Execution strategy
+
+Sessions are owner-gated (each closes with a Design Review and a gate-ledger row stamped with owner disposition + accepted SHA). Waves are Atlas execution batches inside sessions; the DAG is sequential across sessions by owner ruling (brief §6.3/§6.5), with intra-session parallelization only where the matrix marks it.
+
+### Per-wave modeling policy (binding on every tranche-3 authoring todo)
+
+- **Altitude**: subsystem parents at `feature` refining the `spec:protocol.self-hosting` epic; leaf specs at `story`/`feature` as content demands; never a refinement-direction inversion.
+- **Kind**: a validator check earns a `rule` spec when its law is independently statable; bundling is lawful where one law spans several mechanical checks (the pre-declared bundles in M7 — never a count KPI); relation laws live as model facts; durable rulings live as decision specs (the fold), never doubled into ordinary specs.
+- **Anchor density**: anchors only on named realizing entrypoints (the validator functions in `src/validate/validators.ts`, `evaluateReadinessFloor`, `deriveGraph`, `computeDeliveryFacts`, `createReader`, `renderDesignReview`, `generateContracts`, the two reifiers) — 1–3 precise anchors per anchored spec; no decorative anchors; `implemented` stays derived and honest.
+- **Executable bar**: a spec earns `has-verifier` only where the verify loop is genuinely cheap (fixture-based contract binding per the duplicate-IDs tracer template); default `manual`/`reviewed`.
+- **Coverage ledger columns**: concept path (doc §) → spec id → readiness → anchor/verifier status → disposition note. The waves produce a typed, impactable delivery model of the engine — never `docs/concept` in frontmatter form.

+### Docket Ledger, Reconciled at Todo 40
+
+The full close ledger is [task-40 docket evidence](../evidence/self-hosting-phase-2/task-40-self-hosting-phase-2.docket.md).
+Every plan-17 carry-forward, review-06 intake, phase-2 addition, and watch item has one terminal
+disposition. Two rows remain intentionally deferred for phase 2: no-reparse spy coverage because
+named-import interception remains weaker than an injected read seam, and temporal token assembly
+because its carried-forward rationale remains sanctioned. No row was silently dropped.
+

+
+### Anti-Drift Audit, Todo 40
+
+**Verdict: PASS.** The [G7 evidence pack](../evidence/self-hosting-phase-2/task-39-self-hosting-phase-2.g7.md)
+remains the authoritative floor-honest table: 58 corpus Specs, 7 `ready`, 51 `defined`, no
+`idea` or `scoped` state, no orphan, and no unresolved double claim. No filler Spec was accepted:
+the explicit validator filler rejection is recorded in
+[task 35](../evidence/self-hosting-phase-2/task-35-self-hosting-phase-2.filler.log). All five
+watch items are terminal and unfired with a recorded reason. The acceptance-1-to-8 mapping lives
+in [task-40 acceptance evidence](../evidence/self-hosting-phase-2/task-40-self-hosting-phase-2.acceptance.md).
+
+### Watch-item re-check
+
+| Watch item | Current state | Re-check result |
+|---|---|---|
+| table sugar | terminal, unfired | Waves 2-4 used existing sibling Specs and ruled body forms, so no table grammar was forced. |
+| single-literal vocabulary form | terminal, unfired | No new vocabulary carrier needed a form beyond the ruled literal syntax. |
+| multi-entry constraint form | terminal, unfired | No wave introduced a constraint that required multiple entries. |
+| array-section prose sub-owner | terminal, unfired | New prose remains under existing typed section owners. |
+| Markdown Pack syntax | terminal, unfired | The Pack remains a TypeScript manifest, and no caller required Markdown authoring. |
+
+### Planning-review record (durable — every planning finding folded, with its resolution; audit without chat history)
+
+**Metis gap analysis (pre-todo, 17 findings — all folded with each finding recorded):** (1) MD-20 added as the 19th fold spec, landing at the S7 fold-completion against `spec:extraction.excludes` (targets-exist); (2) the fold relation shape restored to both edges — `refines` forward + `decidedBy` back-edges; (3) grammar-matrix confirmation scheduled as todo 2 before emitter design, M1 reworded to the post-gap grammar; (4) plan-18 gate-ledger scaffolding moved to todo 1, gate set unified G1–G8; (5) CLI contract gaps pinned in M2 (per-file fail-collecting, finding split, documentation homes); (6) per-wave modeling policy section added above; (7) watch-item ownership assigned (todos 16, 38, 40); (8) dependency matrix rebuilt contradiction-free; (9) migration + flip one-commit atomicity laws in Commit strategy; (10) measured-evidence split — dispositions at the fold, moves with carrying waves; (11) barrel contract unified: `emitMarkdownSpec` + `importTypeScriptSpec` (both pure, fs-free); (12) D1/D2/D4 carrying specs named in M8/todo 32; (13) Wave-0 single-todo exception annotated; (14) delta catalog lands in the G2 done-record (todo 17), authored-level layer's zero-prose-delta discipline stated in M3; (15) born-spec keep-vs-repoint verdicts at todo 32; (16) the interim-script rename's reference sweep enumerated in todo 22, and todo 1 guards the interim-pinned strings; (17) todo 1 acceptance requires the actual ledger templates, the 10-row hardening skeleton, and PLAN-ONLY markers.
+
+**External consolidated review (post-todo, 9 valid findings folded — one claim rejected):** (1) the glossary-contradiction window closed per Option A — the `sdp import` glossary amendment moved from the flip to todo 7 (verified: no script pins the row's current text), the flip now verifies + machine-pins it; (2) todo 22's acceptance grep rewritten with explicit `--exclude-dir`s and a named active-surface list, plus the standing policy that past-tense historical mentions in plans/reviews/.omo are lawful; (3) MD-16 re-pointed to `spec:validation.readiness-floor` (verified at `src/validate/readiness-floor.ts:150-181` — MD-12 refines the same target); (4) todo 5's pack detection re-based on `CarrierReification.packs` non-empty, with `import/empty` for empty modules; (5) todo 9 gained the drift-alarm QA probe (the rejected claim: renaming `test:protocol.sdp-import.round-trip` — phase-1 convention is `test:protocol.*` for carrier specs too, e.g. `test:protocol.markdown-parser`; the name stands); (6) F1–F4 expanded to phase-1 density with pinned evidence paths, F3 executed as agent-run live QA; (7) this record created so the fold is auditable; (8) acceptance-8 ownership re-aligned (todo 7 now genuinely lands the amendment); (9) todo 5's suite pins pass-through finding identity (`validatorId`/`file`/`line`) for non-error cases.
+
+### Whole-phase done-record
+
+- **Executed delta catalog:** the importer preserves authored `ReifiedSpec.data` with zero prose normalization. The graph comparison normalizes only the carrier file suffix from `.sdp.ts` to `.sdp.md`; physical envelopes and TypeScript source comments remain outside graph content; delivery facts are recomputed under the same anchor set; and `schemaVersion` remains unchanged. The semantic equality gate and the emitted-Markdown authoring-surface review both passed.
+- **Executed delivery:** `sdp import` landed as the durable, fs-free import seam with the CLI write-beside and `--dry-run` boundary; all eleven checkout Specs migrated atomically to Markdown; the canonical-default carrier rule replaced the interim rule; the bounded parser refusal-parity claim, decision-spec fold, and four honest corpus waves landed. The resulting self-hosting graph holds 58 Specs, 1 Pack, and 36 anchors, with 7 `ready` and 51 `defined` Specs.
+- **Session SHA summary:** G1 is `f06f14d`; G2 is `df444f2`; G3 is `0bb200a`; G4, G5, G6, and G8 are consolidated at `67cfda7` under the continuation directive; G7 remains `b471189034e1ee238394f3364c349937be6bebed`.
+- **Watch items:** all five terminal states are unfired. Table sugar was not forced because waves used existing sibling Specs and ruled body forms. The single-literal vocabulary form was unnecessary beyond the ruled literal syntax. No wave required a multi-entry constraint. New prose stayed under existing typed section owners, leaving the array-section sub-owner unfired. The Pack remains a TypeScript manifest, with no caller requiring Markdown Pack authoring.
+- **Deferred tail:** no-reparse spy coverage remains deferred because named-import interception is weaker than an injected read seam. Temporal token assembly remains deferred because the sanctioned temporal-guard pattern still applies; its comment can be narrowed later.
+- **Lean registry rulings:** the phase admitted `spec:decisions.*` records for the executable meta-model, naming and one-primitive laws, binding and section ownership, the typing and readiness-floor laws, one validation path, the `.sdp.ts` extension and carrier ruling, prose ownership, point-per-example, and the exclusion and envelope-grammar contracts. The Pack, agent-surface, and deferred-MCP decisions joined them; D1, D2, and D4 remain carried by their ordinary Specs. Each admission passed the three-part durability test and is linked from the lean registry.
+- **Close evidence:** the acceptance assembly, adversarial-review remediation, and clean-clone and installed-package proofs are recorded in [task 40](../evidence/self-hosting-phase-2/task-40-self-hosting-phase-2.acceptance.md), [task 41](../evidence/self-hosting-phase-2/task-41-self-hosting-phase-2.review.md), and [task 42](../evidence/self-hosting-phase-2/task-42-self-hosting-phase-2.final-proofs.log).

+## §10 Gate ledger G1-G8
+
+This ledger is git process evidence, never graph content. It records owner gates and evidence;
+its rows are not validators and do not alter readiness. `check-self-hosting-gates.mjs` verifies
+the ledger's complete, non-empty G1-G8 structure while the repo plan exists.

+### G7 attached evidence
+
+The manifest-wide coverage-ledger completeness audit and floor-honest readiness table are attached
+in [the G7 evidence pack](../evidence/self-hosting-phase-2/task-39-self-hosting-phase-2.g7.md).
+It records all 58 Pack members, their concept-document contracts, their frontmatter relations,
+and the applicable readiness evidence. The 2026-07-19 owner disposition is accepted because the
+user explicitly directed continuation without incremental owner reviews.

+- [x] 1. Land the repo-facing phase plan, the effort branch, and the plan-18 gate-ledger scaffolding
+  What to do / Must NOT do: Create (or switch to) branch `feature/protocol-self-application-phase-2` — never commit to `main`. Author `plans/18-self-hosting-phase-2.md` in plan-17 shape with these sections in order: (a) status header `🧭 DRAFTED` + spec anchors blockquote (the brief `plans/18-self-hosting-phase-2-brief.md`, plan 17, the carrier ruling MD-18); (b) Context — why this plan exists; (c) Scope (three tranches + §8 out-of-scope mirrored); (d) §1 tranche-1 engineering rulings (the CLI contract from M2, the emitter architecture from M1, the two-layer fidelity contract + pre-declared 5-item delta catalog from M3, the migration atomicity law, the canonical-surface disposition = file-existence-only with `04` §1 repaired to aspirational); (e) §2 the checkout grammar matrix appendix — kind × section × phase-1 support for all 11 checkout specs (the inventory is verified in this work plan's draft Findings; seed cells: the parent `exampleSpace` on `spec:orders.create-order`, multi-relation envelopes up to three keys, the frozen one-entry constraint form — every cell currently maps onto the 17b grammar); (f) §3 the 10-row hardening-matrix skeleton appendix — each TS refusal class from `src/extract/reify.ts:53-64` (parse-error · non-static-envelope · invalid-id · duplicate-id · reserved-property · non-static-section · unowned-prose · unrecognized-statement · unrecognized-property · misplaced-authoring) mapped to `same-class MD finding | named non-claim | checkout-forced cell (empty until ruled)`; (g) §4 tranche-2 fold design (namespace amendment, the pinned 19-row refine-target map from M8, the §4 rubric, fold-ledger template: `registry row → disposition → target spec id → refines target → decidedBy back-edges → evidence surface → three-part-test verdict`); (h) §5 tranche-3 wave design (the per-wave modeling policy verbatim from this plan, the M7 spec lists, coverage-ledger template: `concept path → spec id → readiness → anchor/verifier status → disposition note`, measured-evidence ledger template: `figure → generalized-claim spec → landing wave → move state`); (i) §6 rulings-under-fire running log (empty, seeded with the procedure); (j) §7 sessions S1–S8 with per-session Design Review agendas; (k) §8 docket ledger (plan-17 format: `Docket item (origin) | Planned disposition | Execution state`) seeded with every plan-17 §6 deferred row (all rows at `plans/17-self-hosting-v1.md:445-468`), the review-06 clusters per owner §6.8, the five watch items (table sugar · single-literal vocabulary form · multi-entry constraint form · array-section prose sub-owner · Markdown Pack syntax) each with state `watch`, and the two stay-deferred items; (l) §9 acceptance criteria 1–8 verbatim from the brief with the owning todo numbers from this plan; (m) §10 gate ledger G1–G8 (7 columns like plan 17: `Gate | Meaning | Owner disposition | Date | Accepted SHA | Corrections | Rulings`), all rows `pending`; (n) mark PLAN-ONLY sections (§1–§6 design material) vs execution sections (§7–§10) explicitly. Extend `check-self-hosting-gates.mjs` with a plan-18 block: the G1–G8 gate definitions, pending-tolerant (a row is structurally required; `accepted` + date + SHA required only once stamped — mirror however the script tolerated plan-17's ledger mid-build at `check-self-hosting-gates.mjs:52-61,159-175`), leaving every plan-17 enforcement untouched. Update `AGENTS.md`'s "what now" status clause to point at plan 18 as DRAFTED (plan 17 stays the latest ✅ EXECUTED ground reference) — do NOT touch the interim-carrier-rule sentence pinned by `check-carrier-interim.mjs:43-44` or any other pinned string. Update the docket note in `plans/18-self-hosting-phase-2-brief.md`? NO — the brief is a frozen input record; never edit it. Must NOT: edit any product code, any spec, any concept doc, or the brief; must NOT add gate SHAs (none exist); must NOT wire the carrier/gates audit scripts into `npm run check` (the deliberate non-wiring decision stands, `plans/17-self-hosting-v1.md:385`).

+  Acceptance criteria (agent-executable): `git branch --show-current` prints `feature/protocol-self-application-phase-2`; `test -f plans/18-self-hosting-phase-2.md` and the file contains all fourteen sections (a)–(n) including the two matrix appendices and three ledger templates; `node ./check-self-hosting-gates.mjs` exits 0; `npm run check` exits 0.
+  QA scenarios (name the exact tool + invocation): happy — `npm run check` green with the new plan present (Evidence `.omo/evidence/self-hosting-phase-2/task-1-self-hosting-phase-2.check.log`); failure — temporarily remove a G1–G8 definition from the script block, re-run `node ./check-self-hosting-gates.mjs`, confirm exit 1 with a naming failure, revert (Evidence `.../task-1-self-hosting-phase-2.gates-failure.log`).
+  Commit: Y | `docs(plans): land the phase-2 self-hosting plan (drafted) with gate-ledger scaffolding`
+- [x] 2. Confirm the checkout grammar matrix against the real tree (PLAN-ONLY verification, evidence-producing)
+  What to do / Must NOT do: Walk all 11 checkout spec files cell-by-cell against the frozen 17b heading→section map and envelope grammar; for each spec record: kind, altitude, readiness, every section used, every relation key used, and the 17b row that covers it (or `GAP — no ruled form`). The expected result (verified at planning): all 11 covered — behavior/epic/feature with `intent`+`behavior.rules` → `## Intent`/`## Behavior`; workflow flows → `## Workflow`; exampleSpace vocabulary → `## Example space` + one `gwt-vocabulary` fence; example bound points (full and partial `{n: 0}`) → one `gwt` fence immediately after `## Intent`; contract/idea with blocking openQuestions → `### Open questions` `- [blocking]`; rule → `## Rule`; constraint single entry (flavor/statement/target, no measurableBy) → `## Constraints` one-entry form; model terms → `## Model`; decision (decision/rationale/consequences) → `## Decision`; verification executable+criteria → `## Verification — executable`; relation keys seen (refines, dependsOn, constrainedBy, decidedBy, verifies) all in the envelope's six-key set; multi-target `dependsOn` sequences → sequence form; every spec has `title:` → H1; none has `narrative:`. Also cross-check the 10-row hardening-matrix skeleton: for each TS refusal class, note the MD-side finding ID candidate or `non-claim candidate` (from the MD finding inventory at `src/extract/markdown-support.ts:3-13`, `markdown-body.ts:35-37,72-93`, `markdown.ts:100-111,158-196`, `markdown-body-content.ts:233-241`, `markdown-body-owner-support.ts:26-35`). Record the confirmed matrices in the repo plan appendices (edit plan 18 §2/§3 cells from `unconfirmed` to `confirmed` with this evidence).

+  What to do / Must NOT do: Create the `src/import/` module (a write path — the boundary against read-only `src/extract/` is ruled). Implement `emitMarkdownSpec(reified: ReifiedSpec): string`, a pure function producing the `.sdp.md` document: frontmatter with exactly `id`, `kind`, `altitude`, `readiness`, `relations` (key order as listed; `relations: {}` when empty — the honest carrier syntax, `check-carrier-interim.mjs:48-49`'s relations distinction); relation records (`{type,target,claim:"declared"}` from `reifyTypeScriptCarrier`) grouped by type preserving first-seen key order and per-key list order, scalar for a single target, sequence for multiple, all six keys supported (refines, dependsOn, constrainedBy, decidedBy, verifies, supersedes); H1 from `data.title` (the parser maps H1 → `data.title`, `src/extract/markdown-body.ts:133,189`, so round-trip holds); `data.narrative` as CommonMark prose between H1 and the first H2. Deterministic byte output for identical input. TDD: write the failing tests FIRST (`test/import-emit-markdown.test.ts`) — envelope-only spec, each relation key, multi-target sequence, empty relations, title→H1, narrative placement — quote the RED output in evidence, then implement to green. Must NOT: read or write files (pure — no `node:fs` import); consume graph nodes (the graph is derived; the emitter consumes the authored IR only); emit any key beyond the envelope grammar (title/narrative are never frontmatter — `17b:122-129` forbids them); re-validate (MD-14 — no second validation path).

Prose ownership by construction: every prose slot lands under its owning heading — unowned prose must be unrepresentable in the emitter's output path (MD-19). Idiomatic formatting: one blank line after the frontmatter closer and around every H2, fences opened/closed in column 1 with no attributes — the emitted bytes must look agent-authored, matching the born specs' style. TDD: RED first with one fixture per section form (mirror the checkout specs' real content — they exercise every form), then green.

+  What to do / Must NOT do: Add `importTypeScriptSpec(sourceText: string, relativePath: string): ImportResult` where `ImportResult = { emitted?: { path: string; content: string }; findings: Finding[] }` — pure, fs-free. Behavior: run `reifyTypeScriptCarrier(sourceText, relativePath)`; if it yields findings at error severity, return `{ findings }` with the reifier's `extract/*` findings passed through UNCHANGED (single-sourced finding currency) plus a wrapping `import/refusal` info noting which file refused; classification is by the reification's **content, never by count coincidence**: `import/pack-unsupported` only when `CarrierReification.packs` is non-empty and `specs` is empty (a genuine pack-only module — packs stay TS by ruling, owner §6.4); zero specs AND zero packs AND zero error findings → `import/empty` (an empty or exports-less module — never misclassified as a pack, so finding currency never lies); a module yielding both specs and packs emits the spec content and reports `import/pack-unsupported` at info severity for the pack portion (never silently dropped); on success return `emitted.path` = the sibling `.sdp.md` path (same relative path, suffix swapped) and `emitted.content` = `emitMarkdownSpec(...)` per spec — one spec per file is today's carrier reality (Markdown produces one spec per document, `src/extract/markdown.ts:246-270`); if a TS file ever yields multiple specs, return `import/unsupported-construct` naming the condition (never guess a split). Export `importFindingIds = { refusal: "import/refusal", packUnsupported: "import/pack-unsupported", targetExists: "import/target-exists", unsupportedConstruct: "import/unsupported-construct", empty: "import/empty" } as const` (`targetExists` is consumed by the CLI layer, todo 7).

+  What to do / Must NOT do: Add the fourth verb to `src/cli/sdp.ts`. Usage line: `sdp import <path...> [--dry-run]`. Argument parser `parseImportArgs` (new, mirroring `parseBuildArgs` at `src/cli/sdp.ts:103-172`): one or more positional paths (files or roots, resolved against cwd), `--dry-run` flag, unknown flags rejected with `sdp import: ...` on stderr + exit 1 (the `--exclude --foo` diagnostics lesson — name the offending flag). Behavior per resolved `*.sdp.ts` file (roots scan recursively; `*.pack.sdp.ts` yields `import/pack-unsupported` and continues): read source, run `importTypeScriptSpec`; if the sibling `.sdp.md` already exists, emit `import/target-exists` (never overwrite — no force flag in phase 2); otherwise write it (write-beside). `--dry-run`: print `=== <path> ===` + the would-be content to stdout per file, write nothing. Import **never deletes** the `.sdp.ts` (deletion is the migration's own step, todo 13). Exit codes: 0 when every requested file emitted (or would emit, dry-run); 1 when any error-severity finding or any operational error (unreadable file, EACCES on write — one stderr line, never a stack trace). Findings rendered with the one `formatFinding` (`src/cli/sdp.ts:87-94`). Add the verb to `SDP_HELP_TEXT` (`src/cli/sdp.ts:17-42`) with the same documentation density as the other verbs (arguments, output mode, refusal-never-throw, exit codes) and to the dispatch guard at `src/cli/sdp.ts:526`. For deterministic error-path coverage, extend the injection seam: an `ImportHooks`-style hook object (readFileSync/writeFileSync/existsSync/importTypeScriptSpec substitution) riding the existing `CliHooks` discipline (`src/cli/sdp.ts:49-62` — deterministic producers substitute unreachable branches, never a chmod trick). TDD: RED first — help text mentions import, dry-run writes nothing, write-beside lands, target-exists refuses, pack refuses, bad flag exits 1, refusal exits 1 with findings — then green. **In the same change, land the load-bearing glossary amendment** (review-folded, Option A — the shipped verb must not contradict the ratified glossary for three sessions): rewrite the `sdp import` row at `CONTEXT.md:150` from "the one-way gen-1 `.feature` converter: parser half carrier-neutral, document emitter authored once in the winning carrier" to the multi-adapter verb — one import verb, many source adapters, sharing the document emitter authored once in the winning carrier; the TS→`.sdp.md` adapter landed; the gen-1 `.feature` adapter designed-in and deferred (verified safe: no check pins that row's current text — the interim script pins the transition-clause sentence, `check-carrier-interim.mjs:43-44`; the truth script's CONTEXT scan is the TS-mention audit, which this row does not trip). The flip (todo 22) then machine-pins the amended row via the truth-script re-pin. Must NOT: add a second validation path (no `validateGraph` call, no re-parse of the emitted file); add `--exclude`/`--check-clean` (not this verb's surface); delete or rename any source; touch the interim-pinned `CONTEXT.md` resolved entry (`:238-243`) in this todo — only the `:150` glossary row moves.

+- [x] 13. The checkout-v1 migration — all 11 IDs in ONE atomic commit
+  What to do / Must NOT do: FIRST capture the pre-migration baseline: on the pre-migration tree run `node ./dist/cli/sdp.js build examples/checkout-v1` and copy `examples/checkout-v1/generated/graph.json` to the evidence dir. Then migrate: for each of the 11 checkout spec files run `node ./dist/cli/sdp.js import <file>` (write-beside), REVIEW every emitted document against the authoring-surface bar (idiomatic under the ruled grammar + prose ownership — if any emitted document is not something an agent could have authored, FIX THE EMITTER, never hand-edit the spec — tracer-bullet discipline; any grammar gap becomes a §6 ruling under fire, recorded when made), then delete the `.sdp.ts` source. All 11 emits + all 11 deletes + any emitter fixes land as ONE commit (the atomicity law — no blessed commit holds both surfaces of an ID). Then prove fidelity: rebuild and run the graph-level round trip (todo 8 harness) of post-migration `examples/checkout-v1` against the baseline — deep-equal under the delta catalog; also run the authored-level assertion on all 11 pairs from git history (`git show HEAD~1:<path>` for the TS originals). The pack manifest `checkout.pack.sdp.ts` stays TS and unchanged (lawful per-ID rule). Confirm `npm run typecheck:examples` still passes (the TS spec modules are gone; nothing should import them — verify with `grep -r "\.sdp" examples/checkout-v1/src examples/checkout-v1/test` that no code imports a spec module; anchors live in impl/test files, untouched). Must NOT: hand-edit emitted Markdown (emitter fix or §6 ruling only); delete the pack manifest; commit the migration in pieces; edit `generated/` (untracked, regenerated in-pipeline).

Keep the tracer-bullet framing intact. Must NOT: claim the TS DSL is retired (it survives as import source + per-ID option); touch the interim-pinned strings elsewhere (this README is not one of the interim script's surfaces, but keep the carrier story consistent with the pre-flip rule — the example migrated under the ruled flip procedure; the post-flip anti-misleading pass re-reads this file at todo 22).

+  What to do / Must NOT do: Put the concrete decision to the owner at this session's Design Review (never "polish later"): **Prompt** — "Design Review rendering, two pre-existing debts (review-06 lines 271–275): (a) dynamic-key ordering follows in-memory insertion order, so a re-parsed `graph.json` can render different bytes; (b) escaping stops at narrative/descriptions — titles, rules, terms, criteria render unescaped. Options: (1) escape every rendered field uniformly + sort dynamic keys lexicographically at render (recommended — deterministic from any parse source; uniform safety; tiny output churn on the current corpus); (2) escape prose slots only + sort keys (keeps the TS-carrier HTML-in-title posture, narrows the fix); (3) record a trusted-authored policy and change nothing (names the risk accepted)." On the owner's ruling, implement the ruled option with determinism tests: a permutation test proving byte-identical renders from shuffled insertion orders (the GWT permutation precedent fixed in review-06's addendum), and escaping tests for the newly covered fields. Record the ruling in plan 18 §6 and the docket. Must NOT: change rendered information content (ordering/escaping only); let the escaping policy differ per field after the ruling (uniform per the ruled option).

+  What to do / Must NOT do: Eight fixes in the Markdown parser/reifier, each RED-first: (a) YAML 1.2 scalar spellings (`1e3`, `0x1F`, `-.inf`) — correct the non-string-scalar classification so refusal messages classify right; (b) yaml-native error line numbers vs rebased `finding.line` off-by-one — pin the rebasing; (c) `...` document-end accepted before a later `---` closer — pin acceptance/refusal explicitly (choose the stricter honest behavior, record in the docket); (d) non-mapping-root refusal discards previously accumulated findings — preserve them; (e) depth/node-cap finding flood — bound to one finding per offending node (or the recorded bounded policy); (f) heading/GWT strictness — the example-kind `gwt` fence must sit immediately after the Intent block; `### Open questions` trailing whitespace accepted per the frozen trim rule; H1/H2 titles ending in `#` — pin the ruled behavior; (g) duplicate `When` double-report — single finding; remove the dead `mapOwner` branch; (h) `reifyMarkdownCarrier` catch-all totality — add the wrapper backstop mirroring the TS reifier's (`src/extract/carrier.ts:55-82`) so any unexpected throw becomes a finding, never a crash. Keep every fix inside the ruled grammar — grammar changes are §6 rulings, recorded when made.

The executed matrix fills plan 18 §3's skeleton cells with finding IDs and evidence links. TDD: the probe suite asserts each cell's recorded expectation — a cell whose expectation is `same-class finding` fails if the MD probe doesn't refuse with that class. Must NOT: measure against pre-todo-18 behavior (the debt fixes settled it — parity is paid once); claim parity for any cell marked non-claim; expand the matrix to every ts-morph diagnostic (bounded to authored fidelity by design).

(b) Records cluster (owner §6.8): repair the stale provenance wording `approval provenance is git-native` at `docs/concept/05-validation-and-honesty.md:106` and `CONTEXT.md:182` (align with the glossary's rejection of the term — the line is pre-existing, outside phase-1's scope, deliberately adopted now); record the plan-16 §6 per-item REPAIRED/SUPERSEDED evidence dispositions into the docket (they currently exist only in ignored evidence); narrow the overclaimed comment in `check-carrier-truth.mjs` (the formatter-re-wrap tolerance claim, review-06 lines 287–288) to match its line-based Family-C matching.

+- [x] F1. Plan compliance audit — independent of worker self-report: walk all 43 todos + gates G1–G8 + the docket ledger + acceptance criteria 1–8 against the executed evidence. For each todo: its commit exists on `feature/protocol-self-application-phase-2` (`git log --oneline`), its acceptance command re-passes at the final SHA, its evidence artifacts exist under `.omo/evidence/self-hosting-phase-2/`. For each gate: the plan-18 §10 row carries owner disposition + date + SHA and the gates script passes. For each acceptance criterion: the assembled evidence (todo 40) links resolve. Any todo whose evidence is missing, whose acceptance re-fails, or whose commit message doesn't match its scope = CHANGES REQUESTED. Evidence `.omo/evidence/self-hosting-phase-2/final/F1-plan-compliance.md`.
+- [x] F2. Code quality review — the engineering surface on a fresh clone: public API review (`emitMarkdownSpec`/`importTypeScriptSpec`/`importFindingIds` signatures, no fs in the library seam, no accidental export), refusal totality (both reifiers + the import path convert every throw into a finding — probe with malformed inputs), path/exclude safety (write-beside never escapes the source directory; exclude normalization post-debt-fix), packaging (the packed tarball's `dist/index.d.ts` surface, bin wiring, no repo-internal imports), plus a lint/typecheck/coverage pass of the full gate on the clone. Evidence `.omo/evidence/self-hosting-phase-2/final/F2-code-quality.md`.
+- [x] F3. Real manual QA — executed as **live end-to-end QA, agent-executed (zero human intervention)**: on a clean clone run the full `npm run check`; run the packed-tarball `sdp import` smoke (todo 11 script at the final SHA); re-run the marquee negative probes (the half-flip docs-agree failure from todo 22 if still relevant post-flip, the drift-alarm from todo 9, the corrupted-twin round-trip from todo 8); spot-check the generated Design Review (`npm run generate:self-hosting`) for the new corpus rendering (decision specs, the enriched `spec:carrier.sdp-import`, the migrated example view). Evidence `.omo/evidence/self-hosting-phase-2/final/F3-live-qa.md`.
+- [x] F4. Scope fidelity — intended-truth audit of the phase diff (`git diff main...HEAD`): every Must-NOT verified — no dual-authored product spec ID at any blessed commit (`git log --name-status` sweep for same-commit `.sdp.ts`+`.sdp.md` pairs of one ID outside todo 13's atomic migration), no second validation path (the import path never calls `validateGraph`/`extract` on its output), no TS DSL retirement (`reifyTypeScriptCarrier` exported, fixtures intact), no concept-doc deletion, no content-quality validator, no Markdown pack syntax, no gen-1 `.feature` adapter, no phase-3 bleed (no systematic test rewrite); and the CONTEXT/DECISIONS lean-registry state matches the fold ledger exactly. Evidence `.omo/evidence/self-hosting-phase-2/final/F4-scope-fidelity.md`.
+
+## Commit strategy
+
+Conventional commits on `feature/protocol-self-application-phase-2`, one commit per todo unless the todo says otherwise; `npm run check` green at every blessed commit. Two atomicity laws: **the checkout migration (todo 13) is a single atomic commit** — all 11 emits + all 11 TS deletes together, so no blessed commit ever holds both surfaces of an ID; **the flip (todo 22) is a single commit** — records + script re-pins + anti-misleading + `04` §1 together, so docs-agree checks never see a mixed state. Gate-stamp edits (repo plan ledger row + gates-script SHA) ride the session-close todo. Push only when the owner asks. Never `git stash`.
+
+## Success criteria
+
+The brief's acceptance criteria 1–8 (`plans/18-self-hosting-phase-2-brief.md` §7), each made checkable by the todo that owns it: (1) the flip is total and recorded — no TS-canonical product spec ID under blessed roots, operative surfaces moved in step, scripts retired/re-pointed, no active interim-rule claim (todos 13, 22–24); (2) round-trip fidelity proven under the pre-declared delta catalog, `npm run check` green on the full clean-clone sequence, installed-package proof for the new public surface, the authoring-surface bar judged at the migration's Design Review (todos 8, 11, 13, 17, 42); (3) the hardening non-claim resolved on the parser specs (todos 18–21); (4) the fold complete by disposition, not by count — every registry row, D1–D6, and measured evidence carries exactly one recorded disposition, `DECISIONS.md` is the lean registry, the namespace uniform, no reference dangles (todos 29–34, 38); (5) all four corpus waves land honest — floor-cleared readiness, precise anchors, coverage-ledger rows, no filler kinds (todos 25–28, 35–39); (6) every fired watch item ruled, every unfired one survives named — the five named items' states recorded in the docket/done-record and re-verified at the close audit (todos 16, 38, 40); (7) the docket ledger continues — plan-17 deferred rows carried or dispositioned, adopted clusters landed, owner-gated Design Review per session plus the whole-phase gate (todos 1, 12, 17, 21, 24, 28, 34, 39, 40, 43); (8) `sdp import` documented — the ratified-glossary amendment landed at todo 7 (verified and machine-pinned at todo 22), the CLI contract (arguments, output mode, finding IDs, exit codes, refusal-never-throw, help text) pinned by tests (todo 7), the installed-package smoke covers the verb and the barrel (todos 11, 42) — each owning todo credited only for work it does.

+# Plan 19 — Review-08 remediation
+
+> **Status:** ✅ EXECUTED — review-08 remediation complete; final architecture review blockers,
+> repeated full gate, and live product probes all passed.
+
+## Goal
+
+Resolve every valid major and minor finding from review 08, plus the adjacent note-level defects
+that close the same contracts. Preserve the carrier, one-graph, conformance-and-honesty, and
+never-delete-source laws. Record observations that have no governing defect instead of silently
+inventing policy.
+
+## Validated disposition
+
+| Item | Disposition |
+|---|---|
+| R-1 | Fix: import rollback uses the shared never-throw removal path, preserves the publish error, and names every survivor. |
+| R-2 | Fix: recursive import discovery shares the extractor's built-in directory exclusions and never follows discovered directory symlinks. A new user exclusion flag is not required to close the reproduced defect. |
+| R-3 | Fix: lawful-but-unrepresentable TS shapes refuse with the first divergent authored path; title-less Specs name the required H1 boundary instead of emitting a fabricated title. |
+| R-4 | Fix: package imports are trusted by specifier; relative imports are trusted only when they resolve to this runtime package's canonical builder modules. No public trust override. |
+| R-5 | Fix: escaping follows Markdown context. Prose, headings, links, and tables escape; fenced JSON and inline code preserve literal data with context-specific encoding. |
+| R-6 | Fix: every delivery-fact spelling is reserved in Markdown frontmatter and parity evidence covers them. |
+| R-7 | Fix: replace both `localeCompare` uses with code-unit comparison. |
+| R-8 | Fix: `AGENTS.md` describes the lean decision registry and routes rationale to git, plans, and carrying Specs. |
+| R-9 | Fix: import computes and reports every source result before returning; any failure publishes nothing. |
+| R-10 | Fix: canonical physical source identity deduplicates aliases before both dry-run and publication. |
+| R-11 | Fix: a mixed Spec+Pack carrier refuses publication and names the required source split; import never creates a guaranteed duplicate-carrier state. |
+| R-12 | Fix: an explicitly named non-carrier file is an `import/invalid-source-path` error even when other operands are valid. |
+| R-13 | Fix: Pack findings are computed before the multi-Spec refusal and both are returned. |
+| R-14 | Fix: the public typed emission error is exported beside the public function that throws it. |
+| R-15 | Fix: the authored claim says finding-class parity and records severity/outcome asymmetry. |
+| R-16 | Fix: a frontmatter finding flood retains the frontmatter finding id. |
+| R-17 | Fix: directive findings point at the directive line. |
+| R-18 | Fix: `CONTEXT.md` no longer sends rationale readers to the lean registry. |
+| R-19 | Fix: D3, D5, and D6 point to their carrying decision Specs. |
+| R-20 | Fix: the example-space comment describes context-aware escaping, not verbatim rendering. |
+| R-21 | Fix: import findings use the shared `error`/`warning` severity vocabulary. |
+| R-22 | Fix with scoped regression coverage for the R-3 refusal family, public typed error, omitted kinds/sections, and multi-target relations. |
+| R-23 | Fix the contract-bearing tail: atomic no-clobber publication, `--` operand termination, path-free messages, no fabricated lines, and no dead branch. SIGKILL residue is not claimed recoverable. |
+| R-24 | Record only: control characters have the same authored latitude as TS strings; no carrier law forbids them. |
+| R-25 | Fix: own-property checks prevent inherited names from producing false duplicate diagnostics. |
+| R-26 | Fix with R-5: fenced JSON sorts and emits raw keys, so visible order and copied data agree. |
+| R-27 | Partial fix with explicit exception: internal builder imports become relative. The two stable-id anchor casts remain the bootstrap seam because same-module local builder calls are intentionally not recognized as imported Protocol bindings. |
+| R-28 | Record only: test granularity is real maintenance debt, but the systematic executable-spec rewrite is the named next program and this remediation does not churn the 2,282-line corpus test. |
+| R-29 | Fix: the registry explains that retired/reserved decision numbers are never reused. |
+| R-30 | Record only: root and example corpora are separate extraction roots and no current namespace collision exists. |
+| R-31 | Already resolved by review 08; re-run the temporal guard only. |
+
+## Architecture rulings
+
+### Anchor-builder trust
+
+Raw relative spelling is not authority. The extraction boundary constructs an internal binding
+scope from the runtime package's physical modules. `@libar-dev/software-delivery-protocol` always
+qualifies. A relative import qualifies only when importer-relative resolution, including the
+TypeScript `.js`-to-`.ts` convention, canonicalizes to this package's `ids` or
+`model/code-anchor` module. Consumer-local lookalikes therefore mint no anchors, while deeply
+nested Protocol source imports remain eligible. This is drift repair to the documented
+import-binding contract, not a new public option.
+
+### Import transaction
+
+The CLI workflow separates scan, plan, prepare, and publish. Scanning is bounded and canonical;
+planning reads and reifies every source and checks every target before writing. A failed plan
+publishes nothing. Preparation writes exclusive temporary siblings. Publication uses atomic
+hard-link creation so an existing target cannot be replaced; temporary names are then removed.
+Rollback attempts every temporary and every target created by this invocation through the shared
+never-throw removal helper, reports the original failure first, and never includes a TS source.
+Dry-run consumes the same complete plan as publication.
+
+### Markdown rendering contexts
+
+Markdown text positions use field escaping. Fenced JSON canonicalizes object key order but leaves
+keys and string values raw before `JSON.stringify`. Inline code uses a delimiter longer than any
+backtick run in the value. No global escape or global exemption is lawful.
+
+## Execution order
+
+1. Add RED regressions for anchor trust; extract protocol-binding recognition to a small internal module and fix R-4.
+2. Replace Protocol package self-imports and document the necessary stable-id bootstrap casts (R-27).
+3. Split the import CLI responsibility out of `src/cli/sdp.ts` without behavior change.
+4. Add RED regressions for R-1/R-2/R-7/R-9/R-10/R-12/R-23; implement bounded canonical planning, fail collection, atomic publication, and never-throw rollback.
+5. Fix import finding currency and mixed/multi carrier behavior (R-11/R-13/R-21).
+6. Split emitter helpers before adding R-3 diagnostics; export the typed error and add the scoped round-trip coverage (R-3/R-14/R-22).
+7. Fix reserved frontmatter vocabulary and parity semantics (R-6/R-15).
+8. Fix frontmatter/body diagnostic accuracy (R-16/R-17/R-25).
+9. Split Design Review section rendering without behavior change, then implement context-aware literal rendering (R-5/R-20/R-26).
+10. Repair operative navigation and decision-registry drift (R-8/R-18/R-19/R-29), update carrying Specs, and regenerate self-hosting projections once.
+11. Run diagnostics, focused suites, strict TypeScript audits, `npm run check`, and live CLI/library/view probes. Mark this plan executed only after all pass.
+
+## Verification contract
+
+- Focused tests: import CLI, pure import/emitter, round trip, extraction/parity, Markdown reifier,
+  Design Review, barrel/package smoke, and self-hosting graph.
+- Static checks: diagnostics on every changed TypeScript file, lint, format, typecheck, example
+  typecheck, and the no-excuse audit.
+- Full gate: `npm run check`.
+- Manual surfaces: real built `sdp import` roots for exclusions, symlink aliases, multiple refusals,
+  explicit non-carrier operands, `--` operands, mixed carriers, and target collision; built library
+  import for the typed emission error; real `sdp view` output for fenced JSON and inline code;
+  consumer extraction for local builder lookalikes.
+
+## Done record
+
+- Every accepted R-1 through R-23, R-25 through R-27, and R-29 remediation landed. R-24, R-28,
+  and R-30 remain recorded observations without an invented policy; R-31 remained resolved.
+- The import boundary now scans bounded canonical sources, reports all planning failures before
+  writing, publishes with atomic no-clobber links, rolls back through never-throw recovery, and
+  never deletes a TypeScript source.
+- Builder trust now follows package import or physical Protocol module identity. Consumer-local
+  lookalikes produce no anchors; source, installed ESM, and CommonJS package surfaces pass.
+- Design Review now encodes prose, fenced JSON, and inline code according to their Markdown syntax
+  contexts. Import fidelity reports the first divergent authored path, and Markdown refusal
+  diagnostics retain the correct finding class and location.
+- Final architecture review found two edge-path blockers after the first green gate: an exclusive
+  temp-create failure could remove an unowned path, and source canonicalization could throw past
+  the CLI boundary. Regressions now prove rollback removes only created artifacts and
+  canonicalization failures collect while healthy siblings continue planning.
+- `npm run check` passed: lint and format, package build, both typechecks, 461 repository tests,
+  the isolated 54-test CLI suite, deterministic self-hosting and example checks, and preflight.
+  The gate was run with the remediation's new files staged: preflight classifies untracked non-ignored files as runtime garbage by design, so `npm run check` requires a staged-or-committed tree.
+  The self-hosting graph remains 58 Specs, 1 Pack, 36 anchors, 95 nodes, and 180 edges with zero
+  findings.
+- The strict TypeScript no-excuse audit passed across every changed and added TypeScript file. LSP
+  diagnostics report zero errors across the changed CLI module; broader directory requests were
+  intermittently unavailable, while the repository compiler, linter, declaration build, and
+  package smoke test supplied the full static proof.
+- Live QA drove the built CLI through `--help`, dry-run with no target write, successful publication
+  with source preservation, existing-target refusal, explicit invalid-operand refusal, and the
+  public ESM barrel exports.
+
+### Closing wave — after the done record above
+
+Four repairs landed after that gate run, three of them fallout from the anchor-trust ruling and the
+`setOwn` cluster reaching surfaces the remediation waves had not swept:
+
+- **Serialization keeps author-controlled keys.** The `setOwn` law stopped at reification; an
+  authored `__proto__` key survived extraction and then vanished in the canonical section
+  serializer, which rebuilt sections with plain assignment. The serializer now uses `setOwn` too,
+  so the carrier-to-graph path is own-property throughout, with a regression pinning it.
+- **The agent workspace leaves the published tree.** `.gitignore` excludes `.omo/`, yet an
+  arbitrary slice of it had become tracked: the whole phase-2 workspace, but only five of the
+  remediation session's ~30 evidence files and one of its four notepads. That partial snapshot is
+  what forced a temporal-guard exemption for an ignored directory. The slice is untracked (the
+  files stay on disk), and the exemption is deleted with it — enumeration already honours
+  `.gitignore`, so the guard needed no carve-out once the tracking was honest. The durable
+  ledgers were archived into this directory for exactly this reason; the `.omo/…` evidence links
+  inside the archived phase plans stay session-local pointers, never published artifacts.
+- **Preflight regenerates at trusted package identity.** Builder trust is physical identity to the
+  *running* package's modules, so a clean-room copy driven by the repository's own binary lawfully
+  loses every relative-import anchor. The first repair dropped the clean room and re-ran in place —
+  which, sitting downstream of `generate:*` and both `--check-clean` legs in the same chain, proved
+  little beyond two consecutive runs agreeing.
+- **The clean room is restored, correctly this time.** The scratch root now carries `dist/` and
+  `package.json` beside the sources and executes *its own* `sdp`, so `nearestPackageRoot` lands
+  inside the copy and relative builder trust holds there. Preflight compares the committed tree
+  against a regeneration performed entirely outside this checkout: 58 Specs, 1 Pack, 36 anchors,
+  95 nodes, 180 edges, byte-identical. Relocation-independence is proven rather than assumed, and
+  the trust ruling is now something the gate exercises instead of something it had to concede to.
+- Gate at close: `npm run check` green end to end — 478 repository tests plus the isolated 54-test
+  CLI suite, both `--check-clean` legs, and the restored preflight clean room.

+# 07 - Self-hosting phase-2 adversarial code review
+
+**Reviewed:** the full `main..HEAD` phase-2 diff through `8f5aabe`, plus this review's verified
+remediation. The reviewed phase spans the TS-to-Markdown import surface, the atomic checkout
+migration, the canonical-default flip, the decision fold, and the four corpus waves.
+
+**Method:** independent adversarial passes re-read the full branch history and changed surfaces,
+then reproduced import loss, batch-publication, docs-agreement, fold, corpus, and package-contract
+risks against the built product. Findings below are based on probes, not on prior task receipts.
+
+---
+
+## Verdict
+
+**APPROVE WITH RECORDED FOLLOW-UPS.** The phase's historical checkout migration is atomic, the
+canonical-default carrier rule agrees across its operative records, the fold is now a lean pointer
+registry, and the corpus floor remains honest. Two correctness blockers in the durable import
+surface and three related changes requests were fixed and re-probed. No BLOCKER remains open.
+
+The phase-close owner gates are deliberately not advanced here: this todo does not change their
+ledger. Final clean-clone and installed-package final-SHA proof remain owned by todo 42; whole-phase
+acceptance remains owned by todo 43.
+
+### What held
+
+- The checkout migration commit replaces all eleven checkout Spec carriers in one commit: each
+  `.sdp.md` addition pairs with the matching `.sdp.ts` deletion. No historical dual-carrier
+  checkout commit was found after the migration.
+- The post-flip carrier rule is consistent in `AGENTS.md`, `CONTEXT.md`, the decision registry,
+  package README, concept docs, and the checkout walkthrough. The three carrier audit scripts pass.
+- Decision Specs use the `spec:decisions.*` namespace and the current-law decision slots; the lean
+  registry points to each durable decision. The two empty former-diary headings were removed.
+- The corpus reports 58 Specs, one Pack, 36 anchors, 95 nodes, and 180 edges with no self-hosting
+  validation errors or warnings. Its readiness distribution remains 7 `ready` and 51 `defined`.
+- The installed package exposes the intended import/barrel symbols and the packed dry-run path.
+
+---
+
+## Blocker findings (2) - remediated
+
+### B1 - Successful import silently dropped valid TS-authored content
+
+**Where:** `src/import/emit-markdown.ts` previously selected only the first constraint, example,
+and `when` step. It also omitted string-form open questions and unsupported open-bag properties.
+
+**Probe:** valid TS carriers with two constraints, a string open question, two `when` steps, or a
+structural title each reified without findings; their emitted Markdown lost data or changed structure.
+
+**Remediation:** `emitMarkdownSpec` now reifies its own document and requires exact authored-data
+equality (normalizing only the canonical relation order and physical empty-relations spelling).
+`importTypeScriptSpec` converts an unfaithful emission into `import/unsupported-construct` with no
+emitted target. The public emitter throws its typed `MarkdownEmissionError` rather than returning a
+silently changed document.
+
+**Re-probe:** the focused 38-test import/CLI/package suite passed. The log is quoted in
+`.omo/evidence/self-hosting-phase-2/task-41-self-hosting-phase-2.review.md`.
+
+### B2 - A failed multi-source import could publish a partial migration
+
+**Where:** `src/cli/sdp.ts` previously wrote each output while walking sources.
+
+**Probe:** a directory containing a Pack carrier and an importable Spec exited nonzero but still
+created the Spec's Markdown sibling.
+
+**Remediation:** CLI import now collects and validates all sources and targets before publication,
+writes temporary files first, then publishes them together; a write/publish failure removes all
+temporary and newly published targets. The Pack-plus-Spec regression now proves no sibling exists.
+
+**Re-probe:** `test/cli-import.test.ts` passed with the failed batch leaving its valid target absent.
+
+---
+
+## Changes requested (3) - remediated
+
+### C1 - A requested path with no TS carrier falsely exited zero
+
+**Remediation:** `sdp import` emits `import/no-sources` and exits one when discovery produces no
+`.sdp.ts` source. The focused CLI re-probe passed.
+
+### C2 - The public import API could return its source path as a target
+
+**Remediation:** `importTypeScriptSpec` requires a `.sdp.ts` source path and returns
+`import/invalid-source-path` otherwise. The API re-probe passed.
+
+### C3 - Flip guidance still described checkout Markdown as typed/typechecked and MD-15 as TS-only
+
+**Remediation:** `CONTEXT.md`, `AGENTS.md`, the checkout walkthrough, and the carrier-truth rule
+now distinguish Markdown-default authoring from the lawful TS carrier. All carrier audit scripts
+passed after the repair.
+
+---
+
+## Medium / low findings - owner-visible dispositions
+
+- **M1 - Packed import only exercises dry-run.** Deferred to todo 42's final installed-package
+  proof, which owns a final-SHA package run. The current package smoke still proves the tarball,
+  bin wiring, root exports, and dry-run non-write behavior; this review did not represent that as
+  a write-mode proof.
+- **M2 - `npm run check` does not embed carrier-rule/truth scripts.** No code change here: the
+  phase deliberately owns those scripts as explicit flip/fold audits, and this review reran all
+  three. Todo 43 owns any final gate composition ruling.
+- **M3 - Earlier clean-clone evidence predates the final corpus.** Deferred to todo 42 by design;
+  it must produce a fresh-clone receipt at the final audited SHA. This review does not reuse it.
+- **M4 - G4/G5/G6 remain pending in the process ledger.** No change: the user explicitly forbade
+  ledger mutation in this todo. G7 remains accepted; todo 43 alone may record whole-phase owner
+  acceptance.
+- **M5 - Six validation Specs name implementation entrypoints without individual anchors.** No
+  change: they are `defined`, do not author a delivery fact, and the phase's no-decorative-anchor
+  policy rejects inventing bindings just to make every prose locator derive `implemented`.
+
+---
+
+## Verification addendum - remediation confirmed
+
+The re-probes ran after the remediation, not from worker reports:
+
+- `npm test -- test/import.test.ts test/cli-import.test.ts test/import-emit-markdown.test.ts test/import-round-trip.test.ts test/package-smoke.test.ts` passed: 5 files, 38 tests.
+- `node ./check-carrier-rule.mjs`, `node ./check-carrier-truth.mjs`, and
+  `node ./check-self-hosting-gates.mjs` all passed.
+- `npm run check` passed after the final review artifacts and repairs; its self-hosting report was
+  58 Specs / 1 Pack / 36 anchors -> 95 nodes / 180 edges with zero errors and warnings.
+
+The detailed commands and captured output excerpts are in
+`.omo/evidence/self-hosting-phase-2/task-41-self-hosting-phase-2.review.md`.

+# 08 - Self-hosting phase-2 pre-merge branch review
+
+**Reviewed:** the full `main...feature/protocol-self-application-phase-2` diff at `f8648c4`
+(42 commits, ~264 files), using the executed phase plan (`plans/18a-self-hosting-phase-2-execution.md`,
+the durable copy of the orchestrator's plan) and its evidence ledgers as context.
+
+**Method:** five parallel adversarial passes, one per dimension — the pure import/emit surface, the
+`sdp import` CLI verb and the `--exclude` surface, the Markdown carrier hardening and the
+refusal-parity matrix, the projections/model/graph/reader surfaces, and the authored records
+(specs corpus, decision fold, operative docs, audit scripts). Every finding marked **CONFIRMED**
+was reproduced by a probe against the built product or the real repo state, not inferred from a
+code read. This review deliberately does not re-report the findings of
+`reviews/07-self-hosting-phase-2-code-review.md`; instead it re-probed those remediations (they
+held — see "What held") and hunted for what that review missed.
+
+**Disposition:** compiled for a follow-up session. No product file was changed by this review.
+The one working-tree repair made alongside it (banned temporal tokens in the uncommitted
+`.omo` close notepad, which turned `check:temporal` red) is recorded as R-31 and was fixed
+before commit. **The follow-up session then ran on this same branch** — see the remediation
+addendum at the foot of this document and `plans/19-review-08-remediation.md` for the
+per-finding dispositions.
+
+---
+
+## Verdict
+
+**SOUND TO MERGE, WITH A RECORDED FOLLOW-UP DOCKET.** The phase's central guarantees held under
+adversarial probing: the emitter's fidelity gate refused every lossy shape thrown at it (no silent
+data change was found on any path), the migration's batch-atomicity held under normal failure, the
+carrier-rule flip is consistent across every operative record, the fold's 21 pointers all resolve,
+and the 58-spec corpus extracts clean with honest readiness. The majors below are defects in the
+*durable* import/render surfaces — robustness, scoping, and diagnostic-quality debts — not in the
+phase's fidelity or honesty claims. None of them corrupts authored data or falsifies a derived
+fact on the repo's own pipeline today; two (R-4, R-5) can mislead or misfire in **consumer**
+repos and should be treated as the head of the follow-up docket.
+
+---
+
+## Major findings (8)
+
+### R-1 — A rollback removal failure crashes `sdp import`, abandons the rollback, and hides the original error
+
+**Where:** `src/cli/sdp.ts:284-288`. **CONFIRMED** (probe against `dist/cli/sdp.js`).
+
+The publish-failure catch block calls `remove(path, { force: true })` raw; `force` only swallows
+ENOENT. An EACCES/EPERM/EBUSY on the first removal throws *out of the catch*, escaping
+`runImport` as an uncaught exception: a Node stack trace (violating the CLI's own one-line
+diagnostic law), the loop never reaches the remaining paths — so a **partially published target
+persists**, which is exactly the state the review-07 B2 remediation exists to prevent — a temp
+file leaks, and the original publish error is swallowed entirely. `runBuild`/`runView` treat this
+identical scenario as a first-class law via `removeArtifact`/`removeArtifacts`
+(`src/cli/sdp.ts:401-433`: never-throw + name-the-survivor, with injected-seam tests); import
+bypasses that machinery. **Fix direction:** route the rollback through the same never-throw
+removal helpers and report both the publish error and any surviving paths.
+
+### R-2 — The import root scan is unbounded: it recurses `node_modules`/`dist`/`generated`/dot-dirs and writes into them
+
+**Where:** `src/cli/sdp.ts:158-177` (`collectImportPaths`). **CONFIRMED** (two probes).
+
+Extraction discovery deliberately skips `node_modules`, `dist`, `generated`, `coverage`, and
+dot-directories (`src/extract/discover.ts`); the import scan shares none of that, and `sdp import`
+has no `--exclude`. Probed consequences: (1) `sdp import .` on a root whose `node_modules`
+contains a dependency shipping a `*.sdp.ts` **writes a `.sdp.md` inside `node_modules` and exits
+0**; (2) a directory symlink cycle under the root (routine in pnpm layouts) aborts the whole batch
+with a bare `ELOOP`. Also an unbounded scan cost over `.git`/`node_modules`. **Fix direction:**
+share the discovery exclusion set (and consider the repeatable `--exclude` flag) on the import
+walk.
+
+### R-3 — A family of lawful TS Specs cannot be imported, and the refusal never names the divergent field
+
+**Where:** `src/import/emit-markdown.ts:230` (title), `:84-109` (intent/GWT nesting);
+`src/import/markdown-fidelity.ts`. **CONFIRMED** (four probes).
+
+`title` is optional in the TS DSL (the repo's own parity fixtures omit it and reify cleanly), but
+the emitter renders `` `# ${String(data.title)}` `` → `# undefined`; the fidelity gate then
+rejects its own emission. A kind-`example` Spec without `intent` is likewise unimportable (the
+ruled grammar's only home for the example `gwt` fence is inside `## Intent`, and an empty emitted
+`## Intent` reifies as `intent: {}` ≠ absent), as is any authored-empty owner record, and
+duplicate relation entries. In every case the CLI refuses with the same opaque
+`import/unsupported-construct — … the emitted Markdown does not preserve the authored Spec data`
+message: nothing names the construct or the field, so a batch-migration user gets no actionable
+diagnosis. The refusal direction is *safe* (the gate is doing its job; no corrupt document lands),
+but the verb's usefulness to adopters depends on refusing precisely. **Fix direction:** emit a
+real refusal for absent-title/absent-intent shapes (or rule an emitter form for them), and make
+`MarkdownEmissionError.reason` name the first divergent path.
+
+### R-4 — Protocol-builder recognition by generic relative specifiers can mint false anchors in consumer repos
+
+**Where:** `src/extract/reify.ts:204-215` (`protocolBuilderModuleSpecifiers`) wired through
+`src/extract/index.ts:208`. **CONFIRMED** mechanism (probe: a file importing `spec`/`specId` from
+its own `"./ids.js"` reifies a spec); flagged independently by two review dimensions.
+
+The self-hosting corpus needed the Protocol's own source to be anchor-eligible, so the raw-text
+gate now trusts the generic specifiers `"./ids.js"`, `"../ids.js"`, `"./code-anchor.js"`,
+`"./model/code-anchor.js"`, `"../model/code-anchor.js"`. Anchor candidacy spans every `.ts` file
+in a consumer repo: a consumer file importing a symbol *named* `codeAnchor` from **their own**
+module spelled `./code-anchor.js` gets its calls reified as `impl:` anchors → `satisfies` edges →
+**derived `implemented` delivery facts from non-protocol code** — a name-coincidence path to false
+machine truth in a system whose core law is "delivery facts are derived, never authored."
+Conversely the set is depth-limited: a legitimate Protocol-internal anchor imported via
+`"../../ids.js"` is not recognized and vanishes **silently** (fail-safe direction, but invisible
+drift). Nothing today breaks the repo's own pipeline (all current sites sit at depth ≤ 1), and no
+test pins the consumer-repo false-positive surface. **Fix direction:** scope the trusted-specifier
+gate to the Protocol's own tree (or an explicit opt-in), and pin both directions with tests; this
+deserves a recorded ruling.
+
+### R-5 — The uniform escaping policy corrupts values rendered inside fenced code and code spans
+
+**Where:** `src/projections/design-review.ts:485-506` (`renderOpenBag` via `renderDynamicRecord`
+at `:129-135`); inline-code sites at `:467`, `:626`, `:628`. **CONFIRMED** (the branch's own test
+asserts the corrupted output).
+
+The session-2 ruling ("one escaping policy covers every rendered field") was applied to
+markdown-*literal* positions where escapes are never decoded. Open-bag values are escaped and then
+`JSON.stringify`-ed into a ` ```json ` fence: authored `&` displays as `&amp;`, `<` as `&lt;`, and
+`|` double-transforms to a displayed `a\|b` — visibly mangled data, and anything copying the JSON
+out gets wrong values. `test/design-review.test.ts` locks the corruption in
+(`'"surface": "Review &lt;design&gt; &amp; safely."'` asserted inside the JSON block). The
+escaping has zero protective value there — `JSON.stringify` already neutralizes everything that
+could close the fence. The same category error applies to inline code spans (verification `mode`,
+findings `where`/`validatorId`), where entities and backslash escapes render literally. **Fix
+direction:** exempt markdown-literal positions (fenced code, code spans) from the entity/escape
+policy — `JSON.stringify` is already the correct encoder for the fence — and update the ruling's
+wording plus the now-stale "renders verbatim" comment (R-20).
+
+### R-6 — The Markdown frontmatter's reserved-vocabulary set misses the three delivery-fact names
+
+**Where:** `src/extract/markdown-yaml-policy.ts:12-21`. **CONFIRMED** (probe on all three names).
+
+`reservedEnvelopeKeys` bans `claim`/`deliveryFacts`/`nodeType`/`specKind`/`satisfies`/`verifies`/
+`belongsTo`/`models` but not `implemented`, `has-verifier`, `observed` (the TS carrier's
+`RESERVED_DERIVED_PROPERTIES` includes all delivery-fact names, and the Markdown *body* set does
+too — only the frontmatter envelope omits them). Authoring `implemented: true` in `.sdp.md`
+frontmatter therefore classifies as `extract/unrecognized-property` ("looks like a typo") instead
+of `extract/reserved-property` ("you authored derived vocabulary"). Not an honesty *bypass* — the
+carrier is still refused with an error either way — but it breaks the same-class parity claimed
+for `extract/reserved-property` by `specs/carrier/markdown-parser.sdp.md`; the parity matrix
+passes only because its fixture happens to use `deliveryFacts`. **Fix direction:** add the
+delivery-fact names (both spellings) to `reservedEnvelopeKeys` and widen the parity fixture.
+
+### R-7 — Two new `localeCompare` sorts violate the repo's own determinism law
+
+**Where:** `src/cli/sdp.ts:172-173` (the import directory walk) and
+`src/import/markdown-fidelity.ts:30` (the fidelity gate's relation-sort normalization).
+**CONFIRMED** as code fact (not reproduced across locales).
+
+`src/extract/serialize.ts:20` states the law: "Sorting is code-unit string comparison, never
+`localeCompare`: locale-aware collation is environment-dependent." The import walk orders
+multi-target processing — and therefore finding/report order — by ICU collation, which can differ
+across machines. The fidelity-gate instance is locale-*consistent within a process* (both sides of
+the equality sort with the same comparator), so it cannot flip an equality verdict, but it is the
+same banned pattern in a surface whose whole point is determinism. **Fix direction:** replace both
+with the existing `compareCodeUnits` pattern.
+
+### R-8 — `AGENTS.md`'s "Where to look" row still describes the pre-fold DECISIONS.md diary
+
+**Where:** `AGENTS.md:59`. **CONFIRMED.**
+
+The row advertises `docs/concept/DECISIONS.md` as "**the why-log** … (the ratified-name registry +
+the MD-series, the R-series, the legacy D1–D6 shorthand, measured evidence) — rationale + open
+tensions." Post-fold, that file is a ~48-line lean registry containing none of that — no R-series,
+no measured-evidence section, no rationale — and its own header says rationale lives in git,
+plans, and the Specs. The flip's anti-misleading pass swept the status header two paragraphs above
+but missed this row. An agent onboarding via the top operative record is sent to the registry for
+rationale and finds pointers, then may dig the deleted diary out of git and treat it as current.
+**Fix direction:** rewrite the row for the lean registry (and the companion pointer at
+`CONTEXT.md:7`, R-18).
+
+---
+
+## Minor findings (12)
+
+- **R-9 — Batch diagnostics are fail-fast, not "per-file fail-collecting."** `src/cli/sdp.ts:246-254`
+  returns at the first source with an error finding/refusal/existing target; later sources'
+  findings are never computed. The phase plan's contract for the verb says per-file
+  fail-collecting (the authored spec is silent). A 50-file migration with 6 bad carriers takes 6
+  runs to see all six diagnostics. **CONFIRMED.**
+- **R-10 — Same physical source via two spellings defeats dedupe; dry-run diverges from execution.**
+  Dedupe is a string-keyed `Set` (`src/cli/sdp.ts:232`); a symlinked dir or case-differing path on
+  a case-insensitive FS validates clean, publishes the first twin, then fails blaming *its own
+  just-published file* ("Markdown target already exists"), rolls back, exit 1 — while `--dry-run`
+  prints both twins and exits 0. Rollback held in both probes; the message and the
+  preview/execution divergence mislead. **CONFIRMED.**
+- **R-11 — A successful mixed Spec+Pack import (exit 0) guarantees the next `sdp build` fails.**
+  `src/import/import.ts:88-121`: the Spec twin is emitted with only an info finding; the Spec now
+  exists in both carriers, the TS source cannot be deleted (the Pack must stay TS), and nothing
+  tells the user the remedy is hand-editing the Spec out of the TS file. Next build:
+  2 × `extract/duplicate-id`, graph not written. **CONFIRMED.**
+- **R-12 — An explicitly named non-carrier operand is silently ignored** when any other source
+  emits (`src/cli/sdp.ts:161-165`, `:257-260`): `sdp import good.sdp.ts order.spd.ts` (typo) exits
+  0 with no diagnostic for the typo'd operand. **CONFIRMED.**
+- **R-13 — The multi-Spec refusal drops the Pack finding.** `src/import/import.ts:76-86`: the
+  `specs.length > 1` early return fires before `packFindings` is computed, so a two-Spec + Pack
+  module reports only `import/unsupported-construct`. **CONFIRMED.**
+- **R-14 — `MarkdownEmissionError` is thrown by a public barrel export but not exported.**
+  `src/index.ts:9-11` exports `emitMarkdownSpec`, whose documented failure mode is the typed
+  error; consumers cannot `instanceof`-match it (dist probe: `MarkdownEmissionError === undefined`
+  on the barrel). **CONFIRMED.**
+- **R-15 — The parity claim is id parity, not refusal parity.** `test/extract-parity.test.ts:187-195`
+  asserts exact `validatorId` containment (good) but neither severity nor extraction outcome;
+  probed inside a claimed same-class row: TS `unrecognized-property` is a **warning that still
+  extracts**, Markdown's is an **error that refuses the document** — the very degrade-vs-refuse
+  asymmetry the matrix's `non-static-section` rationale names as grounds for a non-claim.
+  `specs/carrier/markdown-parser.sdp.md` should say "finding-class parity" or carry the asymmetry
+  note. **CONFIRMED.**
+- **R-16 — The frontmatter finding-cap summary carries the body's finding id.**
+  `src/extract/markdown-frontmatter.ts:191` caps a pure-frontmatter flood under
+  `extract/invalid-markdown-structure` (probed: 99 × invalid-frontmatter + 1 structure-id
+  summary). Pre-existing on `main`, carried through the refactor. **CONFIRMED.**
+- **R-17 — Directive refusal line off-by-one** when `%` is not on the first frontmatter line:
+  `src/extract/markdown-frontmatter.ts:47-54`'s `search(/(?:^|\r?\n)%/u)` returns the offset of
+  the *newline before* the `%`, so the structured finding points one line high while the
+  yaml-native text beside it is right. Pre-existing; line correctness was this cluster's scope.
+  **CONFIRMED.**
+- **R-18 — `CONTEXT.md:7` still says "rationale in `docs/concept/DECISIONS.md`,"** contradicting
+  the lean registry's own header. Companion of R-8. **CONFIRMED.**
+- **R-19 — The D1–D6 table's "Canonical in" column is stale for D3/D5/D6**
+  (`docs/concept/DECISIONS.md:45-48`): they now have decision Specs, but a reader resolving a live
+  `(D5)` citation via the table never learns the decision record exists. **CONFIRMED.**
+- **R-20 — Stale "renders verbatim" comment over the now-escaped example space**
+  (`src/projections/design-review.ts:351-352` vs `:363`) — the comment is the stale side of an
+  intent/realization drift. **CONFIRMED.**
+
+---
+
+## Notes (11)
+
+- **R-21 — `import/*` findings ride severity `"info"`, outside the ratified severity vocabulary**
+  (`src/import/import.ts:19,42` vs `src/validate/contracts.ts:6`). The CLI is safe only because it
+  also keys on `result.emitted`; any consumer filtering `severity === "error"` or exhaustively
+  switching over `Severity` misclassifies import refusals. An undeclared third severity on a
+  shared channel — worth a deliberate ruling either way.
+- **R-22 — Round-trip fixture blind spots:** no `rule`/`workflow`/`contract` kind, no
+  `design`/`ui`/`verification` section, no multi-target relation in the graph-level corpus; no
+  direct test that public `emitMarkdownSpec` throws; no test documenting the R-3 refusal family.
+- **R-23 — Publication hygiene tail:** the never-overwrite guarantee is `existsSync`+`renameSync`
+  and `rename(2)` clobbers (TOCTOU window; `linkSync`+unlink would refuse atomically); temp files
+  leak on SIGKILL between temp-write and publish and nothing sweeps pid-scoped `*.tmp` strays;
+  import finding messages embed the path already carried in the structured `file` field (against
+  `formatFinding`'s own doc law); `--` is rejected so a path beginning with `--` is unreachable;
+  `src/cli/sdp.ts:249` is dead code; `targetExistsFinding`/`noSourcesFinding` fabricate `line: 1`.
+- **R-24 — Control characters flow into spec data** (NUL/BEL in body prose, escaped CR in YAML
+  values) and land verbatim in `graph.json`. Same latitude as TS string literals — hygiene
+  observation, no parity break.
+- **R-25 — Inherited-property lookups produce misleading uniqueness messages:**
+  `- constructor: x` under `## Design` refuses as "keys must be unique" on first occurrence
+  (`Object.prototype` members seen by `!== undefined` checks). Nothing is accepted; message-only.
+- **R-26 — `renderDynamicRecord` sorts raw keys but emits escaped keys**
+  (`src/projections/design-review.ts:129-135`): deterministic, but rendered JSON keys can appear
+  non-lexicographic when escaping reorders (`a|x` vs `ab`).
+- **R-27 — Two anchors import builders via the package name** (`src/graph/schema.ts:1`,
+  `src/codegen/contracts.ts:1` — a self-import cycle that works only through hoisting + the vitest
+  alias + tsup inlining), and `src/ids.ts:133-137` bypasses the builders with raw `as` casts.
+  Extraction re-validates, so no honesty hole; consistency debt.
+- **R-28 — `test/self-hosting-graph.test.ts` is one 2,282-line `it`** with frozen absolute counts:
+  first failure masks the rest; every corpus edit churns the frozen block. Not tautological (it
+  asserts hand-written literals against real extraction) — a granularity/maintenance cost.
+- **R-29 — The MD-3/MD-6 numbering gap is unexplained in the lean registry** (the retired-entries
+  note died with the diary); git-only archaeology required against the registry's own
+  "dispositions" promise.
+- **R-30 — The example corpus shares the `decisions.` id namespace with the root corpus**
+  (`spec:decisions.order-lifecycle` in checkout-v1 vs 21 root `spec:decisions.*`). No collision —
+  the root pipeline excludes `examples/` — convention fragility only.
+- **R-31 — (Resolved during this review.)** The uncommitted `.omo` close-notepad section carried
+  banned temporal tokens (an ISO date, `Wave F…`, a numbered plan-file reference), turning
+  `check:temporal` — and with it the whole green gate — red on the working tree while HEAD stayed
+  clean. Reworded before commit; the gate is green again. Kept on the record because notepad prose
+  is swept by the guard and this is the second time a close-note tripped it.
+
+---
+
+## What held (re-probed, hunted, and clean)
+
+- **Review-07 remediations:** B1 holds and generalizes — multi-constraint, string open question,
+  multi-`when`, structural title, trailing-whitespace/CRLF/leading-`#`/embedded-fence/`---`
+  narratives, and `flows`/`description` injection shapes all refuse loudly; unicode and
+  line-separator prose round-trips faithfully; no silent data change was found on any path. B2
+  holds under normal failure (validation precedes writes; failed batches leave zero targets); C1
+  and C2 hold; `--dry-run` writes nothing on every exercised path.
+- **The parity matrix is rigorous where it counts:** exact `validatorId` assertions per cell,
+  rationale required for every non-claim row, duplicate-id exercised through the full `extract()`
+  path. The review-06 grammar cluster is closed for real (non-mapping-root findings preserved,
+  duplicate `When` once, exact `...`, literal terminal `#`, per-limit single summaries, linear
+  flood behavior: 10k bad headings ≈ 309 ms). The acceptance subset refuses directives, tags,
+  anchors, aliases, complex/duplicate/merge keys, and the review-06 scalar-spelling gaps.
+- **Escaping is injective and deterministic** (the `&`-first order actually fixed a pre-existing
+  non-injectivity), ordering in the render path is code-unit only, and the permuted-insertion
+  determinism test is a genuine byte-identity check.
+- **Anchor honesty:** all 19 new `impl:protocol.*` anchors target existing spec ids, sit within
+  the test-enforced proximity of a named real entrypoint, and no validator was silenced;
+  `validateGraph` over the root corpus: zero findings. `schemaVersion` stays `0.4.0` with no
+  hidden shape change.
+- **The records:** the post-flip carrier sentence is verbatim-consistent across every active
+  surface probed (AGENTS.md, CONTEXT.md, the registry, README, concept docs, JTBD stories, the
+  checkout README, the decision spec); no active doc states the interim rule; all three audit
+  scripts pass; all 21 registry pointers resolve with matching ids; the pinned fold-target map
+  matches the authored `refines`/`decidedBy` edges on every spot-checked spec; 15 sampled corpus
+  specs are substantive with no filler; checkout-v1 is exactly 11 `.sdp.md` + the lawful TS pack
+  manifest, and its README figures reproduce exactly.
+- **The gates:** the full `npm run check` chain is green at HEAD and after the R-31 repair;
+  focused suites across all five dimensions pass (import/CLI/package 38+, parity/hardening/reifier
+  120, projections/reader/self-hosting 59).
+
+## Suggested follow-up order
+
+1. R-1, R-2 (the two robustness holes in the durable verb), then R-3 (diagnosability) — one
+   session, TDD, with R-9/R-10/R-11/R-12/R-13 riding as the same verb's diagnostic cluster.
+2. R-4 (the anchor-trust scoping ruling) and R-6 (reserved-vocabulary parity) — small, high-honesty
+   value; R-15's claim-wording repair lands with R-6.
+3. R-5 + R-20 + R-26 (the escaping-policy scope repair) — one ruled projection session.
+4. R-7, R-14, R-16, R-17 as a small hygiene batch; R-8, R-18, R-19, R-29 as one records sweep.
+5. The notes (R-21 … R-30) enter the docket for disposition, not necessarily for work.
+
+---
+
+## Remediation addendum — the docket closed on this branch
+
+The follow-up session ran before merge rather than after it, so the docket this review opened does
+not survive into `main`. The per-finding disposition table, the three architecture rulings it
+forced (anchor-builder trust, the import transaction, Markdown rendering contexts), and the
+verification record are `plans/19-review-08-remediation.md`.
+
+- **Fixed:** R-1 … R-23, R-25, R-26, R-27 (partial, with a named bootstrap exception), R-29.
+- **Recorded only, no invented policy:** R-24 (control-character latitude matches TS string
+  literals), R-28 (corpus-test granularity — owned by the named tests-to-executable-specs
+  program), R-30 (root and example corpora are separate extraction roots).
+- **Already resolved:** R-31.
+
+Three rulings are worth reading before touching those surfaces again, because each closed a
+finding by fixing a *contract* rather than a call site: builder trust is physical module identity,
+never a raw relative spelling (R-4); import is a scan → plan → prepare → publish transaction whose
+publication is an atomic hard link and whose rollback never throws (R-1, R-2, R-9 … R-13, R-23);
+and Markdown escaping follows syntactic context — prose escapes, fenced JSON and inline code carry
+literal data under their own encoders (R-5, R-20, R-26).

+- **baseline** — A named approved snapshot whose signed git tag is the approval artifact, with approval remaining outside the authored model.

+# The reader bridges agent entry points to composable graph context
+
+## Intent
+- outcome: Let agents enter the curated graph from the strings, files, and changesets they already have without rebuilding its joins or taxonomy.
+
+## Behavior
+- rule: `createReader` constructs a fresh thin typed loader that decodes graph joins, claims, delivery facts, derived readiness, and validation findings once, then returns plain composable data without persisting state.
+- rule: `findByConcept` and `byFile` bridge strings and extraction-root-relative files to the graph's recorded context.
+- rule: The reader's `blastRadius` surface maps changed files to directly impacted Specs and Packs, their explicit one-hop at-risk neighbors, and every coverage-unknown file.
+- rule: File-level blast radius reports curated graph reach without claiming exhaustive symbol-level usage reach.

+- outcome: Keep the Protocol legible to delivery practitioners without adopting a lifecycle machine.

+- context: Shared delivery vocabulary is useful, but process-state language hides epistemic distinctions.
+- decision: The Protocol adopts established delivery nouns and rejects process state-machine and lifecycle gating.
+- rationale: Invented terminology taxes users, while workflow states reverse the Protocol's conformance-only boundary.
+- consequence: Terms must be concrete, unambiguous, and carry authored-versus-derived status where it matters.

+- decision: Promoted evidence counts only when the promoted Spec holds its natural evidence; authoring-shape honesty rejects authored delivery facts and external `doc:` targets remain deferred.

 # Carrier reification derives the one graph
 
+The graph is the current projection of the repository at a commit. Git holds lifecycle history, so
+removed records disappear from the current graph and a current `supersedes` relation is the only
+forward pointer between records that still exist.
+
 ## Intent
 - outcome: Expose one carrier-neutral derivation seam.
 
 ## Behavior
 - rule: Carrier reification feeds deriveGraph once; no consumer creates a second graph.
+- rule: The graph is flat arrays of typed nodes and edges; hierarchy and containment are expressed by edges rather than nested nodes.
+- rule: Declared relations resolve Primitive to Primitive, while `satisfies` and test `verifies` edges derive from anchors and run from their binding node to the direct Spec target.
+- rule: Delivery facts are computed node facts: a resolving `satisfies` edge contributes `implemented`, and an enabled direct verifier contributes `has-verifier` only to its target.
+- rule: Inferred structural edges are advisory inputs to impact analysis and never become authoritative graph truth.

+# Source anchors bind code without carrying intent
+
+## Intent
+- outcome: Connect implementation, tests, and oracles to Specs while keeping authored intent centralized in the carrier.
+
+## Model
+- **anchor** — A human-written source binding from one code location to one Spec ID, carrying identity, an optional label, and one target only.
+- **code anchor** — An implementation-flavored binding that derives an anchored satisfies edge.
+- **test anchor** — A binding that derives an anchored verifies edge from a test to its target Spec.
+- **oracle anchor** — A binding that records an oracle's models target without deriving a delivery fact.
+- **anchor-constant form** — The top-level const builder call that the MVP extractor reifies; decorator and JSDoc forms remain unextracted representations.
+- **Protocol builder binding** — A builder import from the public Protocol package, or a relative import whose importer-relative resolution — including the TypeScript `.js`-to-`.ts` convention — canonicalizes to this package's `ids` or `model/code-anchor` module; consumer-local lookalike modules confer no binding authority. On the CommonJS package surface the trusted relative-module set is empty (`import.meta.url` is rewritten away), so relative bindings mint no anchors there while package imports stay trusted.

+- **Spec** — The one authored truth-primitive, enriched in place without changing artifact type.
+- **envelope** — The stable outer shape of id, title, kind, altitude, readiness, and relations; sections carry extension detail.
+- **kind** — The true subtype that categorizes a Spec's truth and changes its required detail and validation.
+- **altitude** — The scope position `epic`, `feature`, or `story`.
+- **readiness** — The author-stated design-maturity position `idea`, `scoped`, `defined`, or `ready`, checked against a structural floor.
+- **delivery fact** — A derived realization signal such as implemented or has-verifier; it is never authored readiness.

+- **modelRefs** — References from a Pack to standalone model Specs that carry shared vocabulary.
+- **refinement** — A truth-bearing parent-child relation, distinct from the cross-cutting Pack aggregate.

+- **section** — An optional detail slice of a Spec: intent, behavior, constraints, model, design, decision, verification, or ui.
+- **typing law** — Every section read by a readiness-floor clause has a closed typed shape; unsettled design and ui surfaces remain open bags.
+- **content-only section** — A section carries local content, while relations carry links to promoted standalone Specs.
+- **promotion** — Moving shared or independently reviewed content into a standalone Spec of the matching kind, exclusively rather than alongside inline content.
+- **verifies** — A direct verifier-to-target relation whose enabled test binding can derive has-verifier only for that stated target.
+- **enabled verifier** — An example or direct test with a linked, resolvable test anchor; runner execution and pass state remain outside the graph.

-# Existing intent can later be imported into the ruled carrier
+# TypeScript-carried Specs can become Markdown twins
 
 ## Intent
-- outcome: Name import as deferred work without claiming an emitter exists.
+- actor: A coding agent or maintainer.
+- outcome: Convert a TypeScript-carrier Spec into an idiomatic `.sdp.md` twin beside its source.
+- value: The TypeScript DSL survives as an import source while Markdown becomes the authored twin.
+
+## Behavior
+- rule: Import writes the emitted Markdown sibling beside the TypeScript carrier and never deletes the source carrier.
+- rule: Import refuses an existing Markdown sibling rather than overwriting it.
+- rule: Refusal outcomes retain the TypeScript reifier findings and add import-local findings honestly.
+- rule: Import consumes the TypeScript reifier so source acceptance follows one validation path.
+- rule: A batch scans only bounded source directories, canonicalizes physical carrier identity, and computes every refusal and target collision before publishing any sibling.
+- rule: Publication prepares exclusive temporary siblings and atomically creates targets without clobbering; rollback attempts every artifact, reports survivors, and never deletes a TypeScript source.
+
+## Example space
+```gwt-vocabulary
+Given a TS-carrier spec
+When importTypeScriptSpec runs
+Then the emitted Markdown re-parses to an equal graph
+```
