+= gitbot-fleet report-backs
+
+One JSON envelope per enrolled fleet member (`.gitbot-fleet/enrolment.json`).
+The Hypatia verdict grid reads this directory when it renders, so a
+report-back here is the only way a member's row stops being orange. The
+envelope contract is `docs/VERDICT-GRID-SPEC.adoc` in hyperpolymath/standards;
+the producer is documented in gitbot-fleet's `docs/REPORT-BACK.adoc`.
+
+*How the files get here.* The `fleet` job of
+`.github/workflows/fork-governance.yml` (gitbot-fleet's
+`fleet-report-back-reusable.yml`) runs the enrolled adapters on the PR head
+and uploads the envelopes as the `fleet-report-backs` artifact; the Hypatia
+lane downloads that artifact into this directory just before rendering.
+Nothing is ever committed here: an envelope is evidence about one commit, and
+a committed one would read as current when it is stale. The directory exists
+because this repository's deed declares it
+(`trope-checker_chora.deed`, `:report-backs ".gitbot-fleet/report-backs/"`),
+and it is empty in git on purpose. An enrolled member with no report-back
+renders *orange* ("enrolled, but no report-back was received"), never green;
+do not add a placeholder envelope to turn a row green. Only a real run may.
+
+Only files matching `*.json` are read, so this README is inert.

+= Affirmation-check trust material
+
+`github-web-flow.gpg` in this directory is GitHub's *current* web-flow
+commit-signing public key:
+
+* fingerprint: `9684 79A1 AFF9 27E3 7D1A 566B B569 0EEE BB95 2194`
+* created 2024-01-16, no expiry
+* fetched 2026-10-28 from `gh api users/web-flow/gpg_keys`
+  (the entry with `key_id` `B5690EEEBB952194`)
+
+== Why it exists
+
+The Affirmation Document Gate (`hyperpolymath/cicd-suite`
+`actions/affirmation-check`, run from `main-estate-audit.yml`) classifies the
+signature on the commit that last changed `AFFIRMATION.adoc`. The copy of the
+web-flow key vendored inside that action is GitHub's *previous* key
+(`5DE3E0509C47EA3CF04A42D34AEE18F83AFDEB23`, expired 2024-01-16) — the action's
+own fingerprint allowlist names the new key, but the new key is not in its
+keyring. Every GitHub-signed commit (web merges, squash landings, and the
+test-merge commit a shallow PR checkout consists of) therefore classified as
+`E` ("cannot be checked"), which the gate treats as "bad, revoked, or failed
+verification" and fails on. That was the `estate-audit` failure on PR #102.
+
+The workflow now runs `.github/affirmation-trusted/check.sh`, vendored from
+`cicd-suite@bf7dd95cf49733019343ff485c2f45c6b261839c` with a local repair:
+`E` accompanied by GnuPG's `NO_PUBKEY` is a notice; bad, revoked, and other failed
+verifications still fail. The local script imports both the current and
+historical vendored GitHub keys and rejects them unless their primary
+fingerprints match the two pinned above. This is a contained workaround, not
+the durable trust boundary: gate code in a pull-request checkout is necessarily
+reviewed code, whereas the root fix belongs in `cicd-suite`, whose pinned
+external action can then be restored. If GitHub rotates the web-flow key
+again, re-fetch it the same way and update the fingerprint above in the same
+commit.

+# does NOT follow the redirect for a reusable workflow's `uses:` — every call
+# below therefore died at startup ("workflow was not found", zero jobs, no
+# check run, no comment) from adoption until this repair. Hypatia-current
+# detects the class as WF028; workflow-linter.yml now blocks it locally by
+# asserting each external coordinate's canonical `full_name`. The calls are
+# cross-owner now, so this repository's Actions policy must allow
+# `metadatastician/standards/.github/workflows/*@*` (Settings → Actions →
+# General → selected actions/reusables); hyperpolymath/hypatia's runs of

+# and no fleet assessment could ever appear on a PR here.
+#
+# PR-time Hypatia lives HERE now; hypatia-scan.yml keeps only its push,
+# schedule and dispatch triggers (ADOPTION §3: a lane must not run twice per
+# PR). No job here can write PR comments. The pinned Hypatia reusable still
+# requires security-events: write for SARIF; its contract cannot be reduced

+# patch-bridge.yml — panic-attack Patch Bridge CVE triage, and nothing else.
+#
+# This file replaces static-analysis-gate.yml (2026-10-28). That workflow ran
+# a SECOND, divergent copy of the estate scanner lane beside the canonical
+# one: its own Hypatia build at an older pin than fork-governance.yml's, its
+# own panic-attack assail at a different pin than the verdict grid's, and a
+# "deposit findings" combiner no consumer read. Worse, three of its four
+# evidence paths could not fail honestly: an unavailable Hypatia wrote an
+# empty findings file, and Patch Bridge was invoked as
+# `bridge triage --format json .` — a flag the tool does not accept (the
+# global flag is --output-format; triage takes --output) against a root
+# directory with no supported lockfile — so it errored on every run and the
+# step then replaced the payload with a fabricated all-zero report. The
+# canonical scanner sequence now lives in exactly one place per trigger:
+#
+#   pull_request  fork-governance.yml  (fleet → Hypatia+panic+pons → grid)
+#   push/schedule hypatia-scan.yml     (same reusable, same scanner pins)
+#
+# What remains here is the one analysis that lane does not do: Patch Bridge
+# CVE triage over supported lockfiles (Cargo.lock, mix.lock,
+# package-lock.json, requirements.txt). It is applicability-gated and
+# fail-closed about its own contract:
+#
+#   * No supported lockfile with external dependencies → an explicit
+#     `not_applicable` envelope (today: src/rust/Cargo.lock is deliberately
+#     dependency-free). That is a statement about Patch Bridge's surface,
+#     never a "no CVEs anywhere" claim; other ecosystems keep their own
+#     lanes (Dependabot, CodeQL, the Hypatia grid).
+#   * Applicable → the tool runs per lockfile directory at the SAME
+#     panic-attack pin the standards reusable uses; a non-zero exit or a
+#     malformed/inconsistent report FAILS this check. Findings themselves
+#     stay advisory (🟡): an unmitigable CVE is an architectural decision,
+#     not automatic proof a PR is wrong.

-  # NOTE ON THE VERSION PIN: theorem-b.agda-lib is developed against Agda 2.8.0

-  # asserted, because asserting a version the runner cannot supply produces a
-  # permanently-red gate rather than a signal — and the substantive guarantee here
-  # comes from --safe --without-K, which holds across versions. Verified locally
-  # under 2.6.4.3: All.agda and Smoke.agda both typecheck, exit 0.
+  # TOOLCHAIN: pinned release artefacts, not the runner's apt. ubuntu-latest is
+  # 24.04, whose agda-stdlib is 1.7.3; Theorem B imports Data.Product.Base, which
+  # exists from stdlib 2.0, so `apt-get install agda agda-stdlib` there fails at
+  # scope checking (exit 42) — reproduced 2026-10-13. The job now fetches the
+  # Agda 2.7.0.1 release binary and the stdlib v2.0 source archive, verifies
+  # both SHA-256 sums, and registers the stdlib under the name the .agda-lib
+  # depends on. Verified 2026-10-13 with exactly these artefacts: All.agda and

+  # rather than an asserted one. Four layers, each catching what the previous
+  # cannot:
+  #   1. `lake build --wfail` — the Lean kernel checks every proof, and any
+  #      warning (a stray `sorry` warns; so do deprecations) fails the build.
+  #   2. leanchecker — a separate process re-checks the compiled .olean
+  #      environment from scratch, kernel-only, so an elaborator/macro-level
+  #      accident cannot smuggle a malformed proof term into the environment.
+  #   3. axiom-audit (allowlist = propext, Classical.choice, Quot.sound, and
+  #      nothing else) over EVERY module — catches sorryAx, Lean.ofReduceBool
+  #      (native_decide) and user axioms transitively, through imports.
+  #   4. The `#print axioms` blocks at the foot of each source are re-emitted
+  #      by the build and their output is the human-readable receipt.
   #
-  # nanoda-allow-sorry: false makes an EXTERNAL type checker reject sorryAx, so a
-  # proof cannot be admitted by a `sorry` that the grep above happens to miss
-  # (e.g. one introduced through an import rather than written inline).
+  # WHY NOT nanoda (removed). As configured it never once passed, for a
+  # structural reason: lean-action's run_nanoda.sh detects the module to export
+  # with `grep '^\[package\]' lakefile.toml`, but these lakefiles use bare
+  # top-level keys (no [package] table) and five sibling lean_libs with no
+  # single root module — so detection failed before nanoda ever ran. Two
+  # further defects disqualified it even had it started: it clones
+  # nanoda_lib's floating `debug` branch and lean4export HEAD at run time
+  # (unpinned code executed in the gate), and its generated config sets
+  # `unpermitted_axiom_hard_error: false`, so the "rejects sorryAx" claim
+  # this comment block used to make was false — unpermitted axioms were
+  # advisory. Layers 2+3 above are the pinned, hard-failing equivalents.

-# Static analysis — advisory CHECK, deliberately NOT a blocking gate.
-#
-# Tier: 🟡 CHECK. It was labelled 🔴 Gate for 132 runs and never once failed,
-# because it cannot: it skips when its tools are absent, pipes findings through
-# `|| true`, and carries continue-on-error. Two honest resolutions existed —
-# make it able to fail, or stop calling it a gate. The second is correct here:
-# panic-attack has a known false-positive problem (panic-attack#171), much of it
-# firing on tests and benches rather than shipping code, so blocking merges on
-# it would train people to bypass the gate. Advisory is what it actually is.
-#
-# It was also NOT in any ruleset despite the old header claiming otherwise, so
-# renaming it cannot strand a required context.
-# Runs panic-attack and hypatia, deposits findings for gitbot-fleet learning.

+# K9 files.
+#
+# 1-formats/k9/spec/K9-CONTRACT-SPEC.adoc v1.0.0 (standards) landed AFTER
+# these 8 files did: they are rsr-template boilerplate and pre-contract
+# drafts (missing pedigree.schema_version / pedigree.component_type,
+# unfilled TODO placeholders, a Hunt-leash example with no signature block,
+# two .k9 files that do not parse as Nickel at all). The fork-governance
+# K9 lane could not execute in this repository until 2026-10-28 (the
+# standards repository transfer plus a selected-Actions allow-list gap
+# killed every run at startup), so this debt was never gated before.
+# Turning the whole lane red at first execution is the exact failure the
+# estate has already paid for; the designed alternative is this ledger.
+#
+# The ratchet is one-directional (enforced by standards'
+# k9-conformance renderer):
+#   * a path here that now CONFORMS is a stale entry and fails — fixing a
+#     file must shrink this ledger in the same change;
+#   * a path NOT here that does not conform fails, so new debt cannot
+#     appear;
+#   * a path here that the PR TOUCHES loses its exemption, so this ledger
+#     can never carry a violation through an edit to the file that has it.
+#
+# One repo-relative path per line. '#' comments and blanks ignored.
+# Baseline 2026-10-28, produced by the first executing K9 run
+# (fork-governance run 40782505930, L0–L2 strict, standards@34cf03f9)

+
+*Anchor.* Branch `claude/new-session-snuoro` at `444e4cf` (`main` 216f23b + the v0.2
+consolidation + the `proofs.yml` pin), 2026-10-27T07:56Z, in an Ubuntu 24.04 cloud
+container. Toolchain: Agda 2.7.0.1 + agda-stdlib 2.0 (tag `v2.0`, commit `2b8fff1`);
+Idris2 0.8.0 (built from tag `v0.8.0` on Chez Scheme 9.5.8); rustc 1.97.0; just 1.40.0.
+
+*Ground truth (commands run here):*
+
+* `idris2 --typecheck verification/proofs/idris2/trope.ipkg` → exit 0; 8 modules, all
+  `%default total`; no `believe_me` / `assert_total` / `postulate` in
+  `verification/proofs/idris2` or `src/idris2`.
+* `just trope-build && bash tests/conformance/run.sh` → the reference `tropecheck`
+  builds; *13* verdict cases pass with the expected witness edge and coordinate; *9*
+  schema-invalid documents are rejected at the named slot; "conformance: all pass".
+* `just trope-rust` → `tropecheck-rs` builds; the same 13 + 9 pass — the Rust fast core
+  and the Idris2 reference agree over the whole corpus.
+* `just build-agda` → `agda --safe --without-K All.agda` and `Smoke.agda` exit 0
+  (77 s and 5 s cold; 12 s together with cached interfaces).
+* `just build-lean` → *NOT RUN here*: `lake` is not installed and the Lean toolchain
+  and Mathlib cache hosts were unreachable from this container. The
+  `lean-source-honesty` regexes of `proofs.yml` were run by hand over all 8 tracked
+  `.lean` files: no `sorry` / `admit` / `native_decide`, no user `axiom`. On this
+  branch the `proofs.yml` `lean-build` job (run 40472568287, 2026-10-27T08:18Z) built
+  both packages — `lake build` "Build completed successfully", one axiom line per
+  theorem — and then failed in lean-action's optional `nanoda` step (its lean4export
+  does not compile under the v4.16.0 toolchain), exactly as on `main`; that step, not
+  the build, is why the job is red.
+
+*Proved* (machine-checked; names in `docs/status/PROOF-STATUS.adoc`): L1–L6 on the
+ratified carrier, L4 in full (`fateL4MonoR/L`, `bondComposeMono`, `mergeComposeMono`);
+the decidable retention preorder; the Veridicality Derivation and Honest Generation;
+C1–C3 (`GradeR.conical`, `gradeR_leftCancel_iff`, `TierTwoComplete`,
+`fate-tier-meet-hom-fails`); O1-carrier (`atom_factorization`, stated on the v0.1 `Grade` — finding 4); the sighted tropical
+factorisation (`piR_sighted`); Theorem B Targets 1, 2, 4 and the β/let case of 3
+(`cut-preserves-grade`, `β-app`, `β-let`); grade soundness for exact lowering,
+T-Sub and verdict soundness (`soundFromExact`, `subSound`, `verdictSound`). *Open*
+(`spec/calculus.adoc §10`): CO-1 mechanisation (the `fix` case; designed, not
+mechanised), O1-coord, O2, O3, O5 mechanisation, O6.

+*Four findings.* (1) Ubuntu 24.04's apt pair (Agda 2.6.3, agda-stdlib 1.7.3) cannot
+typecheck Theorem B: `agda --safe --without-K All.agda` exits 42, `Data.Product.Base`
+not found — stdlib ≥ 2.0 is required, which is why `proofs.yml` now pins Agda 2.7.0.1
++ stdlib 2.0 by checksum (reproduced here, 58 s). (2) The 2026-06-22 entry's "10/10"
+and "8 schema-invalid" were stale: the corpus is 13 + 9. Also observed: `just
+proof-check-all` is red for reasons that predate this pass (per-file `idris2 --check`
+and `agda --safe` from the repo root cannot resolve module names; the ABI/Types Idris2
+mint templates do not typecheck) — recorded as an issue, not fixed here; the gates
+that mean something are `just check`, `just build-agda`, `just trope-rust` and
+`verify-all`. (3) The CI axiom audit shows `Trope.nine_families` (`EffectAtoms.lean`),
+`FateA.Q_add_left_cancel` and `FateA.atten_cancel_on_normalForms` (`GradeRatified.lean`)
+depend on `Classical.choice` as well as `propext`/`Quot.sound`; the "`propext`/`Quot.sound`
+only" wording in spec §9.3, PROOF-STATUS and the proofs README overclaimed and now reads
+"no `sorryAx`, no user axiom". `GradeBoundary.lean`'s own footer had said so all along. (4) `EffectAtoms.lean` imports
+`GradeBoundary`, so the atom factorisation cited for O1-carrier is a theorem about the
+v0.1 `Grade`; no `GradeR` restatement exists. The factorisation is componentwise and
+should transfer, but that is an argument, not a proof — recorded in PROOF-STATUS (Open)
+and left for the owner where `spec/calculus.adoc §6/§10` cite it as ratified-carrier.

+Alpha. The IR schema, the executable checker and the conformance suite are green,
+and the verified developments carry no `sorryAx` and no user axiom behind their
+claimed lemmas (the Lean results rest on the standard library's `propext`/`Quot.sound`,
+and `Classical.choice` in three theorems). On the ratified carrier (ADR 0004, R-2026-07-07) the grade algebra is a commutative
+monoid with the three deceptive bottoms as two-sided zeros; L1–L6, conicality, the
+cancellation boundary (left-cancellative iff ε), the Honest Generation and
+Veridicality theorems, the atom factorisation (O1's carrier half — stated on the v0.1 `Grade`,
+not yet restated on `GradeR`) and the tropical factorisations — pre-ratification
+`GradeFactorisation.lean` veridicality-blind, ratified `GradeFactorisationR.lean`
+veridicality-sighted — are proved across Agda, Idris2 and Lean; Theorem B gives
+grade-exact substitution and β/let subject reduction. The
+named open problems are *CO-1* — the operational model for `fix` is designed
+(`spec/notes/2026-07-07-co1-operational-model.adoc`) and awaits mechanisation,
+which is what stands between the exact-lowering soundness already proved and
+full grade soundness — plus O2 (per producer), O3, O5's mechanisation, O6 and
+O1-coord, all listed in `spec/calculus.adoc §10` with their status. Ground truth:
+`AFFIRMATION.adoc`; the proved-vs-open table: `docs/status/PROOF-STATUS.adoc`. The

+= ADR 0005 — Spec v0.2 consolidation, O5 proposed, O6 opened, prover roles, template removal; the carrier-as-parameter question recorded
+:revdate: 2026-10-27
+
+== Status
+
+*Proposed — owner to accept.* Drafted in the Phase 0 pass ("make the status
+surfaces true"); the spec consolidation it ratifies landed as
+`docs(spec): consolidate the calculus at v0.2` (2026-10-13). Nothing here changes
+a semantics; D6 is recorded, not decided. D2 and O5 remain PROPOSED until
+the owner accepts this ADR; the O5 text in §10 is a proposed interface.
+
+== Context
+
+After ADR 0004 (R-2026-07-07) the normative text was split across four
+documents written against two different carriers: `spec/calculus.adoc` v0.1
+(2026-06-22) with the ratification spliced in as notes, the never-merged
+addendum `spec/calculus-v0.2-draft.adoc` (2026-06-23), and the two design notes
+of 2026-07-07 (the L4 boundary and atoms; the CO-1 operational model). The spec
+still said "seven effects" while the vocabulary, `EffectAtoms.lean` and the IR
+said nine. The third firewall ("veridicality is declared and propagated, not
+checked") cited an obligation O5 that §10 never defined; the workbench proposed
+the missing entry on 2026-07-17
+(`trope-particularity-workbench/docs/theory/formalisms/defining-o5-veridicality-oracle.adoc`).
+T-Sub's one-sidedness means the verdict certifies sufficiency only, which the
+privacy direction (a ceiling on retention) cannot use. The estate's proof-kernel
+ruling of 2026-10-12 fixed the role of each prover across repositories, and this
+repo still described itself as a "four-prover" stack and carried three
+never-instantiated Coq / TLA+ / Agda templates from the repository mint.
+
+== Decisions
+
+[cols="1,3",options="header"]
+|===
+| ID | Decision
+
+| *D1 (one normative document)* | `spec/calculus.adoc` v0.2 (the consolidation
+of 2026-10-13) is the normative text. The addendum is folded in and removed; the
+two 2026-07-07 notes and `verification/proofs/INTEGRATION-REPORT.adoc` are
+history and analysis, cited from the spec where they carry the argument, never
+the other way round. Where any older status surface disagrees with the spec, the
+spec wins.
+
+| *D2 (O5 proposed)* | §10 gains O5, the veridicality oracle, proposed for adoption from the
+workbench proposal of 2026-07-17 unchanged in substance: Remark O5-a
+(IR-relative undecidability of veridicality), the oracle interface with O5-1
+soundness, O5-2 attestation and O5-3 no-laundering, the falsifier, and the
+upgrade path (mechanise O5-1 as a side condition on an `Oracle`-indexed verdict
+judgement). Status in §10: PROPOSED pending acceptance of this ADR; mechanisation
+OPEN. Vocarium's warrants are
+O5-2 attestations; Hermeneia's _licensed_ band is where O5-backed claims sit.
+
+| *D3 (O6 opened)* | §10 gains O6, the ceiling verdict: the dual theorem
+stem:[\rho \sqsubseteq g_{\mathrm{ceiling}}] that a "no more than this may be
+retained" use-model needs, which T-Sub's downward-only weakening does not give for
+conservative lowering. Deliverable: the dual verdict proved for the exact-lowering
+fragment and stated as unavailable for the conservative one, or a second,
+upper-bound grade on edges. Status: OPEN.
+
+| *D4 (prover roles)* | The estate kernel ruling of 2026-10-12 applied here
+(§9.3): *Agda* is the normative kernel (Theorem B; CO-1 mechanisation targets it);
+*Idris2* is the executable reference (the verified core and the reference
+`tropecheck`); *Lean 4 + Mathlib* is provenance (the grade-algebra boundary, the
+atom and tropical factorisations, kept with their axiom audits); *Rust* is the
+fast core, validated against the reference over the conformance corpus.
+Consequence: `docs/status/PROOF-STATUS.adoc` leads with Agda, and new
+metatheory goes to Agda unless an ADR says otherwise.
+
+| *D5 (three provers; templates removed)* | `verification/proofs/coq/TypeSafety.v`,
+`verification/proofs/tlaplus/StateMachine.tla` and
+`verification/proofs/agda/Properties.agda` — mint templates whose own text says
+"Replace with your project's …", never instantiated — are removed, with their
+tree and recipe references. The repository describes itself as three provers
+(Agda, Idris2, Lean) plus a Rust fast core.
+
+| *D6 (recorded, not decided)* | Whether the fidelity carrier should be a
+*parameter* — any resource algebra with two adjoined tops, instantiated from
+`hyperpolymath/resource-algebra` — rather than the one instance
+stem:[\mathbb{N}\cup\{\infty,\top\}]. This would answer the "uncalibrated
+ordinal arithmetic" objection (the finite part of the carrier adds losses whose
+unit is unstated) by making the unit the instance's business. O4 is RESOLVED for
+the instance (ADR 0004); the parameterisation is Phase 1A work and is *not*
+decided by this ADR.
+|===
+
+== Consequences
+
+* One place to read the calculus; "nine effects" throughout, reconciled with
+  "seven" as nine atom families of which six are writable and three are faults.
+* The third firewall cites the proposed O5 obligation. O5 is dischargeable in
+  principle (mechanise O5-1) and refutable (its falsifier is stated).
+* The privacy direction has a named obligation (O6) instead of an unstated gap;
+  the verdict's one-sidedness is written down as a limitation, not hidden.
+* Status surfaces (`PROOF-STATUS`, `ROADMAP`, `AFFIRMATION`, the Agda `fix`
+  footer) are rewritten to the ratified world in the same pass; the Lean
+  honesty gate and `verify-all` cover every tracked Lean source.
+* `just proof-check-all` no longer invokes the Coq recipe; `just proof-status`
+  reports three provers. The historical mention of the templates in
+  `INTEGRATION-REPORT.adoc` stays as the record of what was there.
+* D6 leaves the carrier an instance; downstream (vocarium, hermeneia) may keep
+  reading `Attenuated(δ)` with stem:[\delta \in \mathbb{N}].
+
+== Rejected alternatives
+
+* *Keep the addendum as a separate v0.2 document* — rejected: two normative
+  texts on two carriers is how readers and agents kept landing in the
+  pre-ratification world.
+* *"Four-prover" wording, Rust as a prover* — rejected: the fast core proves
+  nothing; it is validated against the reference. Naming it a prover overclaims.
+* *Keep the Coq / TLA+ / Agda templates as future placeholders* — rejected: they

+= 0006 — Scanner-lane sequencing: one canonical lane, explicit clash resolution
+:revdate: 2026-10-28
+:toc: macro
+
+toc::[]
+
+== Status
+
+Accepted; implemented in this repository on 2026-10-28 (PR #107).
+Upstream items are recorded as ready-to-paste prompts at the end.
+
+== Context — how the governance lane vanished silently
+
+This repo adopted the estate fork-governance lane (DEED syntax, K9-DEED
+conformance grid, gitbot-fleet report-backs, Hypatia verdict grid, one PR
+comment) on 2026-10-28, yet no grid or assessment ever appeared on PR #107.
+Root cause, in two layers:
+
+. *The repository had never opted in.* Before `fork-governance.yml` existed
+  here there was no fleet enrolment and the Hypatia caller rendered its grid
+  into an artifact nobody downloaded.
+. *Then the lane's coordinates died.* `standards` was transferred from the
+  `hyperpolymath` user account to the `metadatastician` organisation on
+  2026-10-25 (repository id 1116521501, history preserved). GitHub redirects
+  git clones, web links and REST API calls for the old name — but *not* a
+  reusable workflow's `uses:`. Every standards reusable called from this
+  repo (fork-governance ×4, governance, hypatia-scan, secret-scanner,
+  scorecard, mirror) therefore failed at startup with "workflow was not
+  found", created *zero jobs*, emitted *no check run*, and posted *no
+  comment*. `gh pr checks` showed a clean-looking list in which three
+  workflows were simply absent.
+
+Two defences nearly caught this and didn't:
+
+* This repo's `workflow-linter.yml` re-resolves every external pin — via the
+  redirect-following REST API, which cheerfully resolves commits under a
+  moved name. Resolution ≠ canonicality.
+* Hypatia-current detects the exact class (rule WF028,
+  `reusable_call_to_moved_repository`), but the estate's pinned scanner
+  (standards default `aa34a4c…`) predates WF028 by 135 commits, and WF028 is
+  advisory/low severity, below the scanner's default reporting threshold.
+
+A second, independent defect compounded the first: the local
+`static-analysis-gate.yml` ran duplicate Hypatia and panic-attack jobs at
+*divergent pins* with incompatible semantics (header said "advisory, cannot
+fail"; two jobs could in fact fail on criticals; `ci/CI-CRITICALITY.toml`
+listed it as a merge gate). Its Patch Bridge job had never once executed the
+tool: it passed a non-existent `--format json` flag against a directory
+with no supported lockfile and then *replaced the error output with a
+fabricated all-zero report*. A green check asserted CVE evidence that did
+not exist.
+
+== Decision — the canonical sequence
+
+Per pull request, evidence flows in one acyclic sequence. Each stage has
+exactly one owner; nothing downstream re-derives what an upstream stage
+owns.
+
+[cols="1,3,3",options="header"]
+|===
+| Stage | What runs | Contract
+
+| 0. Coordinate preflight
+| `workflow-linter.yml` resolver
+| Deterministic and blocking: every external `uses:` pin resolves, the
+  repository's canonical `full_name` equals the coordinate as written
+  (moved-repo detector), and every reusable workflow path exists at its
+  pin. This is the gate WF028 cannot be: Hypatia reports it advisedly,
+  the linter refuses it.
+
+| 1. Producers (parallel, read-only, comment-free)
+| DEED syntax · K9-DEED conformance · gitbot-fleet report-backs
+| Each emits artifacts/envelopes only. Fleet executes enrolled adapters in
+  manifest order, so `.gitbot-fleet/enrolment.json` is written in Kin
+  Arbiter priority order (echidnabot > rhodibot > panicbot > sustainabot >
+  glambot > seambot > finishingbot > cipherbot > accessibilitybot).
+
+| 2. Findings lane (needs: fleet)
+| standards `hypatia-scan-reusable.yml`
+| Hypatia (the lane's only gating row) + panic-attack assail +
+  pons-asinorum (advisory status envelopes) → verdict grid → SARIF upload
+  (alert-derived meta-findings excluded at SARIF render, so the upload can
+  never echo back as next run's "findings") → blocking decision taken from
+  the baseline-filtered SARIF, not from raw JSON.
+
+| 3. Publication
+| standards `fork-governance-reusable.yml`
+| Exactly one PR comment, marker-identified, updated in place: summary
+  table, K9 grid, Hypatia grid. Lanes never post themselves; a lane that
+  produced nothing renders orange ("indeterminate"), never absence.
+
+| 4. Disjoint CVE surface
+| `patch-bridge.yml` (panic-attack Patch Bridge)
+| Lockfile CVE triage only. Applicability is computed and recorded as an
+  envelope: with zero supported external dependencies the result is
+  `not_applicable` — a statement about the tool's surface, never a clean
+  bill. Tool failure or malformed output fails the check; findings are
+  advisory.
+
+| 5. Push / schedule
+| `hypatia-scan.yml`, `secret-scanner.yml`, `scorecard.yml`
+| The same reusable and the same scanner pins as stage 2 (baseline/SARIF
+  reconciliation on main). `secret-scanner` carries this repo's one
+  ruleset-required status context, `scan / gitleaks` (ruleset
+  Secret-Scan-Floor; the only other active branch rule is
+  Require-Signed-Commits) — its caller job key must not be renamed.
+|===
+
+== Clash-resolution rules
+
+. *One scanner, one version, per trigger class.* Hypatia `adb2f41…` in
+  every caller (the standards default predates WF028); panic-attack at the
+  standards pin `b689a74…`; pons at the standards pin. Divergent local
+  builds are not defence in depth; they are two truths.
+. *One producer per finding family.* Fleet enrolment declines, with
+  reasons: `panicbot` (panic-attack already has a direct grid row —
+  enrolling it double-counts), `echidnabot` (proofs are gated by their own
+  toolchains in `proofs.yml`; no ECHIDNA engine is configured, so the
+  adapter could only report `not_run` forever), `cipherbot` (no
+  cryptography is implemented here; the hashes present are integrity pins),
+  plus the pre-existing `seambot`/`accessibilitybot`/`sustainabot`
+  declines. Grey rows with reasons beat orange rows without evidence.
+  Active reporters — rhodibot, glambot, finishingbot — carry explicit
+  `"gating": false`.
+. *Gating precedence is singular.* Of the grid rows only Hypatia gates;
+  the lane state is its worst gating row under
+  purple > red > orange > yellow > blue > green, with grey reserved for
+  declared non-applicability. Missing or malformed evidence is orange,
+  never green and never an empty findings file.
+. *No presence proxies.* A step that cannot run its tool must say
+  `not_run`; it must never print a pass. (The cicd-suite
+  `custom-tools-check` composite did exactly that for panic-attack/pons in
+  `main-estate-audit.yml`; the step is removed — see upstream prompt.)
+. *Neural/heuristic layers advise; they do not adjudicate.* Hypatia's
+  neural apparatus may demote or route findings (novelty forces
+  `report_only`) but never creates, promotes or blocks on its own output.
+  Deterministic direct evidence outranks external-alert-derived evidence,
+  which outranks heuristic/neural confidence.
+. *Preflight headers are not conformance.* `dogfood-gate.yml`'s DEED/K9
+  jobs are fast header-level preflights; fork-governance is authoritative
+  on semantics. The scheduled `rhodibot.yml` shell audit is a drift
+  reminder, not Rhodibot evidence — the fleet adapter's report-back is.
+
+== Consequences
+
+* PRs get the K9-DEED grid, the Hypatia verdict grid (Hypatia, panic-attack,
+  pons, three fleet rows, five reasoned grey rows) and the single
+  fork-governance comment — provided this repo's Actions allow-list admits
+  the new cross-owner coordinate (see prompt S1; `hyperpolymath/hypatia`'s
+  2026-10-27 runs show the refusal where it does not).
+* `static-analysis-gate.yml` is retired; `patch-bridge.yml` keeps its one
+  honest job. `ci/CI-CRITICALITY.toml` no longer calls the retired
+  workflow a merge gate.
+* Cross-owner reusable calls are now a *sequenced* dependency: allow-list
+  first, canary second, propagation third. Any future repository transfer
+  must land in the workflow-linter's canonical-name assertion as a failing
+  check with the new owner named, not as a silent zero-job run.
+
+== Canary results (2026-10-28, PR #107 at `60e1600`)
+
+Measured, not predicted:
+
+* 28 check runs success, 1 neutral, 1 skipped, *zero failed*. The new
+  `patch-bridge.yml` runs and uploads its `not_applicable` envelope;
+  workflow-linter (canonical-name resolver + actionlint + zizmor) and the
+  quality regression harness (incl. the new moved-repository fixture) pass.
+* Exactly three workflow runs still `startup_failure` — fork-governance,
+  governance, secret-scan — each annotated: the canonical
+  `metadatastician/standards` reusables "are not allowed in
+  hyperpolymath/trope-checker" under the selected-actions policy. No other
+  cause remains. The one owner action that completes the repair:
+  Settings → Actions → General → "Allow select actions and reusable
+  workflows" → add `metadatastician/standards/.github/workflows/*@*`
+  (see prompt S1 for the estate-wide version). Note the secret-scan lane
+  carries the ruleset-required `scan / gitleaks` context, so main cannot
+  go green until this lands. The fallback, if the allow-list must not
+  widen, is the fork-local reusable pattern (MetaManifold-WebUI) — viable
+  but deliberately not taken here: it vendors ~1,400 lines of upstream
+  YAML per repo to work around one settings pattern.
+* Two canary defects were found and fixed in the same sweep: a missing
+  `actions.lock` entry makes GitHub's dependency locking refuse a new
+  workflow's actions at startup (allowlist-worded error), and the
+  resolver's canonical query needed the regression harness's `gh` stub to
+  answer canonical-name lookups (now a permanent fixture case).
+
+== Allow-list landed; first executions (2026-10-28, PR #107 at `09b3e09`)
+
+The owner added `metadatastician/standards/.github/workflows/*@*`; canary
+push `73f82b9` and follow-up `09b3e09` measured the result:
+
+* *Secret Scan succeeds*, and the ruleset-required `scan / gitleaks`
+  context is present and green for the first time.
+* *Fork Governance completes `success`* (run `40784118396`): DEED 🟢,
+  fleet report-backs ran for the first time (rhodibot 🟢, glambot 🔵,
+  finishingbot 🔴 advisory), Hypatia job success, and the first
+  `fork-governance-verdict` comment was posted *and* regenerated in
+  place on the next run. K9 opened 🔴 (8 of 10 committed K9 files are
+  pre-v1.0.0 template debt) and is now 🟡 via the shrink-only ledger
+  `.machine_readable/k9-contract-debt.txt`, baselined under a declared
+  `Ratchet-exception` — the same grandfathering standards applied to
+  its own 25 files.
+* *Governance runs 20/21 green.* The sole failure, `Allowlist
+  Preflight`, is an upstream canon defect, reproduced locally with the
+  pinned script: `allowed-actions.json` at `34cf03f` (and at standards
+  main `e1f59d5`) still lists `hyperpolymath/*` but no
+  `metadatastician/*`, so the preflight flags the very canonical
+  coordinates the transfer mandates. One-line upstream fix (see prompt
+  S): add `metadatastician/*` to `patterns_allowed`. Until it lands and
+  the pin is bumped, that one job stays red estate-wide for every
+  migrated repo. It is a 🟡 check, not a ruleset-required context.
+* The Hypatia verdict *grid* still paints 🔴 while its *job* succeeds:
+  the gating row's highs are CSA staleness meta-alerts over stored
+  code-scanning alerts (99-day `shell_download_then_run` on
+  `build/setup.sh`, whose advertised `curl|sh` line this PR removed),
+  plus advisory finishingbot template-completeness highs. Grid-vs-gate
+  divergence remains prompt-S/H territory; the blocking SARIF path is
+  clean (0 critical, no unbaselined high in scope).
+
+== Upstream prompts (paste into the named repository)
+
+=== S — `metadatastician/standards`
+
+----
+CONTEXT. The standards transfer (hyperpolymath -> metadatastician,
+2026-10-25) broke every reusable `uses:` estate-wide: REST/git follow the
+redirect, reusable resolution does not. trope-checker PR #107 has repaired
+the caller side (canonical coordinates, a blocking canonical-full_name
+assertion in its workflow-linter, Hypatia pinned to adb2f41 because your
+default aa34a4c predates WF028 by 135 commits). The following belong here:
+
+S1 ALLOW-LIST BEFORE PROPAGATION. hyperpolymath/hypatia run 40451601571
+(and siblings) prove direct canonical calls are REFUSED under the live
+92-pattern selected-actions lists ("not allowed ... must be from a
+repository owned by hyperpolymath or match one of the patterns"), while
+config/settings/actions-allowlist.json already carries 95 patterns incl.
+metadatastician/*. Apply the canon payload estate-wide (prefer the narrow
+metadatastician/standards/.github/workflows/*@* for reusables), canary one
+selected-actions repo, then propagate coordinates. Record the sequencing
+rule in the transfer playbook: allow-list -> canary -> fan-out. Acceptance:
+a hyperpolymath-owned selected-actions repo starts JOBS (not
+startup_failure) calling governance-reusable at the canonical coordinate.
+
+S2 MIGRATE INTERNAL EXECUTABLE REFERENCES. Rewrite remaining in-workflow
+`repository: hyperpolymath/standards` checkouts and any internal `uses:` to
+metadatastician/standards (hypatia-scan-reusable SARIF-filter and grid
+checkouts, fork-governance-reusable canon checkout, governance-reusable
+helper checkouts). Add a CI assertion: no `uses:`/`repository:` under a
+former owner anywhere in .github/workflows. Prose/history may keep the old
+name; executable coordinates may not.
+
+S3 REPIN WITH CANARY + OVERRIDE INPUTS. hypatia-scan-reusable defaults:
+Hypatia aa34a4c -> current vetted (WF028 + StandardsRepo registry);
+panic-attack b689a74 -> 410a8f8 (deterministic assail reports, canonical
+rule-ID table); pons 32e5567 -> bca1ea2 (evidence/report-contract
+hardening). Add panic-ref/pons-ref inputs mirroring hypatia-ref so callers
+can canary. Emit JSON and SARIF from ONE scan run (today the scanner runs
+twice; alert state can drift between projections).
+
+S4 GRID TRUTH-IN-LABELLING. (a) verdict-grid.jq currently grades the
+Hypatia row from raw JSON (incl. code-scanning/dependabot meta-findings)
+while block-on-high grades the filtered SARIF: the grid can say purple
+while the gate passes. Grade the row from the same SARIF-projected,
+baseline-filtered finding set; show meta/alert-derived counts separately.
+(b) Sort report-back rows by the shared canonical priority (Hypatia Kin
+Arbiter order), not artifact/assembly order. (c) fork-governance-render.sh
+labels blue as "high findings" (blue is minor/low; red is high) and ranks
+blue == orange; fix the label and use the explicit precedence
+purple/red > orange > yellow > blue > green > grey across families.
+(d) Add cross-reporter de-duplication: a semantic fingerprint
+(normalised path + line + class/CWE) with `corroborated_by`, preserving
+per-row counts but publishing a unique graded total, so Hypatia/panic/pons
+overlaps are not summed as distinct defects.
+
+S5 SURFACE ADVISORY FINDINGS OPT-IN. WF028 is advisory/low and invisible
+at the scanner's default severity threshold, so even current Hypatia would
+not have shown this outage in the reusable's JSON. Add a
+`hypatia-advisory: true` input (sets HYPATIA_ADVISORY for the JSON
+projection only; SARIF gating unchanged).
+
+S6 ADOPTION DOCS. In 3-practice/fork-governance/ADOPTION.adoc: state the
+Actions allow-list prerequisite for cross-owner callers and document the
+fork-local fallback (MetaManifold-WebUI pattern) as a first-class option;
+show the enrolment example in Arbiter priority order with explicit
+"gating": false on fleet reporters and the panicbot double-count warning.
+----
+
+=== H — `hyperpolymath/hypatia`
+
+----
+CONTEXT. trope-checker now pins Hypatia adb2f41 in every lane (WF028 was
+decisive). Audit of lib/rules, lib/neural, lib/kin at that commit found
+sound funnels (single suppression pass, single verdict pass, SARIF
+self-echo exclusion) but no cross-rule sequencing contract. Requests:
+
+H1 RULE SEQUENCING REGISTRY. Give every rule module a declared phase and
+provenance in one machine-readable registry: (0) inventory/context,
+(1) deterministic direct source/workflow rules, (2) structural/governance,
+(3) external-alert meta-rules, (4) reconciliation, (5) neural advisory.
+Reconciliation de-duplicates on a conflict key (normalised repo-relative
+path + line span + semantic class/CWE), preserves losers under
+also_reported_by, and counts once. Severity conflicts are never averaged:
+direct-source severity governs source flaws; the authoritative alert's
+severity governs its own domain; irreconcilable same-key disagreements
+keep max severity AND a `conflict: severity_disagreement` marker routed
+to review.
+
+H2 META-RULE PROVENANCE. Alert-derived findings (dependabot,
+code_scanning, secret_scanning) must carry origin, instance commit/ref
+and scope (`repository_alert_state` vs `pr_delta`). An alert whose most
+recent instance is not at the scanned head is stale context, not
+delta-graded evidence. Extend the SARIF self-echo exclusion: code-scanning
+meta-findings should be quarantined from ALL graded outputs (JSON grid
+included), not only from the SARIF renderer. Unavailable alert APIs are
+`not_run`, never zero findings.
+
+H3 WF028 GENERIC REGISTRY. Promote the standards-only move table into a
+versioned moved-repository registry (former, current, numeric repo id,
+moved date, evidence/run link). Keep the finding advisory in Hypatia, but
+add certainty/impact/gate_effect fields (deterministic; startup_failure;
+caller workflow-linter blocks) so consumers can sequence it as preflight
+rather than as a low-severity afterthought.
+
+H4 NEURAL (e-r) HARDENING. Per-phase timeouts with explicit not_run trace
+entries — a dead organ must degrade the trace, never crash the
+coordinator call or lose its state. Missing organs contribute NO
+confidence (remove 0.5 defaults in derive_confidence); below quorum
+(RBF + MoE mandatory) emit no neural confidence and force report_only.
+Mark the weighted score as uncalibrated wherever it is displayed. Neural
+output is belief/epi-grade: it may demote or route, never raise severity,
+never satisfy a gate, never override Verdict.level. Reconcile the stale
+docs (5-network hub-and-spoke, fixed weights) with the implemented
+8-organ/6-phase blackboard, and make config (runtime.exs) name the phase
+order it actually starts.
+
+H5 ARBITER: WIRE IT OR STOP CLAIMING IT. Kin.Arbiter is supervised but
+has no production callers, and check_conflicts+register_active (cast) is
+a race. Provide one atomic claim/3 (repo + semantic finding + file set)
+used by FleetDispatcher/TriangleRouter before any MUTATING dispatch,
+completed/released on outcome. Read-only/report-back actions never
+arbitrate — they corroborate. Priority should derive from action risk
+and evidence class (sound/deterministic > authoritative alert >
+heuristic), with bot identity as tie-break only; same-file edits always
+serialise regardless of priority.
+----
+
+=== F — `hyperpolymath/gitbot-fleet`
+
+----
+CONTEXT. The report-back driver executes enrolled members in raw manifest
+order (jq to_entries), so estate behaviour silently depends on each
+repo's JSON key order; standards' renderer then displays rows in assembly
+order. trope-checker has ordered its manifest by Hypatia's Kin Arbiter
+priority and added explicit gating:false, but that is per-repo discipline
+for a fleet-level constant.
+
+F1 ONE CANONICAL PRIORITY. Publish the member priority order as data in
+this repo (single source consumed by the driver, Hypatia's Arbiter and
+standards' verdict-grid renderer — or generated copies with a drift
+test). The driver sorts enrolled members by it regardless of manifest
+order; fix-fleet-enrolment.sh writes manifests in that order.
+
+F2 ENROLMENT LINT. fix-fleet-enrolment.sh (or a new check) should warn on:
+panicbot enrolled where the lane already has a direct panic-attack row
+(double counting); echidnabot/sustainabot enrolled with no engine/adapter
+(permanent not_run presented as enrolment); cipherbot enrolled where no
+cryptographic code exists (checksum pins become findings). Declines with
+reasons are the honest state and should be the suggested fix.
+
+F3 ENVELOPE PROVENANCE. Include adapter + tool version pins and a
+per-finding evidence class + semantic fingerprint (path/line/class) in
+report-back envelopes, so the standards grid can de-duplicate fleet
+findings against Hypatia/panic/pons instead of summing overlaps.
+----
+
+=== Q — `hyperpolymath/cicd-squabbler`
+
+----
+CONTEXT. The standards transfer produced a new estate-wide failure class
+your taxonomy nearly covers: zero-job startup_failure from (a) a reusable
+coordinate under a moved owner ("workflow was not found") and (b) a
+canonical coordinate refused by the caller's selected-actions allow-list
+(hypatia run 40451601571). Both are invisible in PR check lists.
+
+Q1 Classify both as first-class startup failures with distinct moves:
+repoint-to-canonical (same pin) vs allow-list-admission-required.
+`squabble chains` should resolve canonical full_name for every upstream
+coordinate (REST follows redirects — compare names, do not just resolve
+pins) and flag moved/dead upstreams and pin skew BEFORE a run proves it.
+Report attribution per zero-job run: repo, workflow, coordinate as
+written, canonical target, required allow-list pattern. Preserve
+squabble != bypass: diagnosis and sequencing advice only, never a green.
+----
+
+=== P — `hyperpolymath/panic-attack`
+
+----
+CONTEXT. trope-checker's Patch Bridge job never ran: wrong flag
+(--format), wrong directory, error output stubbed to zero. The consumer
+is fixed (patch-bridge.yml: --quiet bridge triage <dir> --output, recount
+validation, fail-closed). Two tool-side gaps remain:
+
+P1 A lockfile that exists but declares zero external dependencies makes
+triage() bail with "No supported lockfile found" (deps.is_empty conflates
+the two states). Return BridgeReport::empty for that case so
+dependency-free projects (trope-checker's src/rust) get a valid report
+instead of an error consumers must special-case.
+
+P2 Discover nested lockfiles (recursive, .git/target excluded) or accept
+repeatable --lockfile paths; the current root-only discovery silently
+misses workspace layouts. Document the bridge CLI contract (global flags
+precede the subcommand; --output writes the JSON; --offline returns NO
+vulnerability data) in README/man — `--offline` in particular must be
+labelled as producing an empty result, never a clean one.
+
+P3 Publish the canonical rule-ID table (410a8f8) with CWE/semantic-class
+mapping as data, for verdict-grid de-duplication against Hypatia/pons.
+----
+
+=== N — `hyperpolymath/pons-asinorum`
+
+----
+CONTEXT. standards pins pons 32e5567; bca1ea2 (8 commits ahead) hardened
+evidence honesty and report contracts. For the repin (standards prompt
+S3), consumers need from pons: the JSON 0.4.0 report contract frozen and
+versioned; the severity/evidence mapping the verdict grid consumes
+(ERROR/WARN/INFO x HEURISTIC/DATAFLOW/PROTOCOL/SPECULATIVE) published as
+data; and a per-finding semantic fingerprint (path/line/class) so the
+grid can mark pons findings corroborated by panic-attack/Hypatia instead
+of double-counting overlaps. SPECULATIVE findings must stay visually
+and numerically demoted in any aggregated count.
+----
+
+=== C — `hyperpolymath/cicd-suite`
+
+----
+CONTEXT. actions/custom-tools-check ("Panic Attack & Pons Gate") prints
+"Custom tools validation passed" when neither binary is on PATH — the
+normal case on GitHub runners — so every consumer of main-estate-audit
+estate-wide has been certifying scans that never ran. trope-checker has
+removed the step (evidence comes from the standards Hypatia lane's
+envelopes). Fix at source: absent tool => explicit not_run status and a
+non-zero exit (or rename the action to an advisory presence check that
+cannot be mistaken for a gate). Audit the sibling *-check composites for
+the same pass-on-absence pattern.
+----
+
+=== G — `hyperpolymath/.git-private-farm` (private; inventory first)
+
+----
+CONTEXT. Public references show the farm as the estate's token-bearing
+propagation actuator (repository_dispatch `propagate`, label/config
+generation, merge actuation design). Apply the transfer sequencing
+lessons inside the farm; do not mass-propagate until each step verifies:
+
+G1 Inventory every template, generator and dispatch payload that stamps a
+standards coordinate or an Actions allow-list; migrate sources to
+metadatastician/standards. Receivers must re-verify before applying:
+target repo + head SHA, canonical full_name of every reusable coordinate,
+workflow path exists at the pinned SHA, and the target repo's Actions
+policy admits the owner — fail closed on any mismatch.
+
+G2 Idempotency and order: key every actuation by (event id, repo, target
+SHA, template version); dedupe repository_dispatch retries; one writer
+per repo at a time; canary batch (one selected-actions repo proves jobs
+start) before estate fan-out. Split read/verify credentials from
+write/actuate credentials, least-scope fine-grained tokens, no farm token
+visible to scanner/build jobs. Log skipped/not_run distinctly from
+applied — a skipped propagation must never read as success. Include the
+caller's full repo name (owner/name) in new payloads; repo-name-only is
+ambiguous across owners.

+3+^| _Metatheory (Theorem B, Agda `--safe --without-K`, zero postulates)_
+
+| Target 1 — intrinsic graded calculus
+| The intrinsic typing judgement encoded by `TB.Syntax` over the ratified grade monoid, with the F4 tiers as closures. This result covers only that encoded calculus; `fuse`, `fix`, and per-field presence tracking are omitted and remain open.
+| Agda `TB.Syntax`, `TB.Grade`, `TB.Tier`.
+
+| Target 2 — grade-exact substitution
+| Cut preserves the grade exactly; grade commutes with cut.
+| Agda `TB.Substitution.{cut-preserves-grade,cut-grade-comm}`.
+
+| Target 3 — subject reduction, β/let core
+| β and `let` steps preserve type and grade exactly; the redex grade is the contractum grade; the tier is preserved; sequencing two core computations stays in the core.
+| Agda `TB.Reduction.{β-app,β-let,let-redex-grade,let-tier-preserved,seq-stays-core}`. (The `fix` case is open: see CO-1 below.)
+
+| Target 4 — Honest Generation and Veridicality
+| Honest grades are closed under composition (`TB.Honest.honest-closed-▷`); the unit and writable effect atoms in `TB.Honest` are honest. This is a grade-level closure result; it does not establish that every typed term has an honest grade.
+| Agda `TB.Honest`.
+
+3+^| _Soundness_
+
+| Grade soundness, exact lowering
+| If the declared grade equals the observed retention, stem:[g \sqsubseteq \rho].
+| Idris2 `Trope.Soundness.soundFromExact`.
+
+| T-Sub soundness
+| stem:[g' \sqsubseteq g \wedge g \sqsubseteq \rho \Rightarrow g' \sqsubseteq \rho].

+| stem:[\mathrm{floor}(U) \sqsubseteq g \wedge g \sqsubseteq \rho \Rightarrow \mathrm{floor}(U) \sqsubseteq \rho].
+| Idris2 `Trope.Soundness.verdictSound`.

+
+== Open
+
+Each is specified; none is asserted. Status words follow `spec/calculus.adoc §10`.
+
+* *CO-1 mechanisation* — the operational model (λ-trope, tagged values,
+  T-Fix-Decl) is DESIGNED in `spec/notes/2026-07-07-co1-operational-model.adoc`;

+  is OPEN. It closes Theorem B Target 3 (`fix`, NOT-REACHED, no postulate) and
+  grade soundness for conservative lowering (`spec/calculus.adoc §7–§8`).
+* *O1-carrier on `GradeR`* — `atom_factorization` and the nine-family results
+  (`EffectAtoms.lean`) are theorems about the v0.1 `Grade`; porting them to the
+  ratified `GradeR` — expected to be mechanical, the factorisation being

+* *O3* — the produce/demand adjunction; the verdict is a subsumption until the
+  triangle laws are checked (`spec/calculus.adoc §6.2`, `§10`).

+
+Faithful-but-simplified choices, recorded for honesty:
 
 * *Provenance tags on `Fused` are erased* in the verified core (they are metadata
   that does not affect the lattice laws); the executable checker carries them.
 * *Deceptive duals are modelled as each coordinate's bottom* (worst retention,
   absorbing), which is how the calculus orders `Conflated`; this makes every
   honest floor fail against a deceptive grade (HC-2) by construction.
-* *L2 is stated with ε's literal value* in Idris (a bare top-level `epsilon` as a
-  function argument does not reduce under the unifier); since
-  `epsilon = MkGrade Present Present Present Present Intact Single` definitionally,
-  the statement is `ε ▷ g = g`.
-* *The use-model floor is a partial per-coordinate demand, not a grade value.* HC-4

   minimum-demands (each coordinate optional), so an author CAN write an incoherent
   floor (e.g. bearer-Dropped + bond-Intact). This is harmless — each demanded
-  coordinate is checked independently — but is an author-error surface, not covered
-  by the HC-4 unrepresentability claim. (Audit 2026-06-22.)
-
-== Soundness advance (2026-06-22)
-
-Newly machine-checked in `Trope.Order` + `Trope.Soundness` (no axioms):
-
-* *⊑ is a preorder* — reflexivity (Trope.Coords) + *transitivity* (`fateLteTrans`,
-  `bondLteTrans`, `mergeLteTrans`, `dLteTrans`, assembled to `gradeLteTrans`).
-* *Verdict-soundness corollary* (`verdictSound`) — `floor ⊑ g ∧ g ⊑ ρ ⟹ floor ⊑ ρ`.
-  This is the calculus §8 corollary, now proved (it is exactly transitivity of ⊑).
-* *T-Sub soundness* (`subSound`) — `g' ⊑ g ∧ g ⊑ ρ ⟹ g' ⊑ ρ`.
-* *Grade soundness for EXACT faithful lowering* (`soundFromExact`) — if the declared
-  grade equals the observed retention (the strongest faithful lowering, O2), then
-  `g ⊑ ρ`, via congruence of ▷ + reflexivity. No L4 needed.
-* *L4 monotonicity holds for the chain coordinates* bond and merge
-  (`bondComposeMono`, `mergeComposeMono`).
-
-=== FINDING: strict L4 monotonicity FAILS for the fate coordinate
-
-`Trope.Soundness.fateL4MonotonicityFails` machine-checks a counterexample:
-`Dropped ⊑ Present` and `Predicated ⊑ Predicated`, yet
-`Dropped ▷ Predicated = Dropped` while `Present ▷ Predicated = Predicated`, and
-`Dropped ⋢ Predicated` (Predicated and Dropped are *intentionally incomparable*,
-calculus §3.1). So strict L4 does not hold for fate; the calculus's "L4 is a *lax*
-compatibility" (§5 note) is load-bearing. Consequence: grade soundness for
-*conservative* (inexact) steps cannot be composed by naive L4 over the fate
-coordinate; the *exact* route (`soundFromExact`) sidesteps it, and bond/merge remain
-monotone.
-
-=== Still open (narrowed)
-
-* Grade soundness for *conservative* lowering over fate — needs the lax argument the
-  calculus hints at, not strict L4.
-* The operational model of the term language + `fix` (calculus §7) and a definition
-  of observed retention `ρ` over executions — the deeper part of the open problem.
-  *This is now named CO-1, the repository's central open problem (see the next
-  section); the two streams converge on it.*

-Two work-streams landed against the *authoritative Lean ground truth*

-Mathlib, sorry-free; `#print axioms` = `propext`/`Quot.sound` only — built green this
-date, no `sorryAx`/user-`axiom`/`native_decide`):

-  \subsetneq \mathcal{G}] — cancellation holds *only* on the finite-fidelity core and
-  fails on the honest-but-lossy and deceptive tiers alike (the non-cancellative set
-  *strictly* contains the deceptive set)

-

-  (≡ Idris `Soundness.fateL4MonotonicityFails`). (B: F2×F4 finding.)

-
-=== CO-1 — CENTRAL OPEN PROBLEM (the repository's headline gap)
-
-*The calculus has no operational model (reduction dynamics) for its grade-routing /
-iterating constructs.* v0.1 is a pure type-and-grade discipline; reduction beyond the
-β/let core is undefined. The two streams *converge on this single hole* from opposite
-sides — recorded as ONE item, not two:
-
-* *Spec face (= A's OPEN-A):* the lossless fractional *split / rejoin / routing*
-  operator whose cancellability R-2026-06-23-03 constrains-in-advance is referenced
-  but *undefined* (no typing rule, no dynamics).
-* *Proof face (= B's Target-3 fixpoint case):* `fix`/lfp subject reduction is
-  *NOT-REACHED* — no ↝ rule for `fix`, no observed-retention `ρ`.
-* *Additionally gated by v0.1 O4* (the `Conat`-vs-tag limit carrier for ordering
-  iterated attenuation beyond stem:[\omega]) — B's second missing piece, which *is*
-  v0.1's pre-existing O4.
-
-The grade algebra is *not* at fault (the lfp endpoint stem:[\{total, unknown\}] is
-already ▷-fixed and tier-stable). *Entanglement:* v0.1 §7 justifies the `fix` lfp
-grade "by L4 monotonicity", but strict L4 is machine-proved to *fail on fate*
-(`fate-L4-fails`) — so even the grade-side `fix` justification rests on a monotonicity
-now known only to be lax.
-
-=== Documentation-reconciliation gaps (recorded, not filled — for the merge author)
-
-* *OPEN-A* — folded into CO-1 above.
-* *OPEN-B* — `Falsified` (fate's deceptive bottom, dual of honest `Dropped`) is in the
-  proved carrier but absent from v0.1 §3.1's four-inhabitant fate table. *OPEN-B′
-  (surfaced during integration)* — the analogous gap holds for `Misbound` (bond's
-  deceptive bottom), absent from v0.1 §3.2's three-inhabitant bond table. (Merge's
-  `Conflated` is already in v0.1 §3.3.) Whether to amend v0.1 §3.1/§3.2 normatively is
-  a documentation decision, not fixed by F1–F4.
-* *OPEN-C* — tier-2 membership is recorded, not exhaustively proved: the harness
-  witnesses *representative* honest-but-lossy elements non-cancellative
-  (`predicated`/`severed`/`total`, +`dropped`); `Withheld` and `Fused` sit in tier 2
-  by the carrier's order structure but carry no individual named non-cancellation
-  witness in either development.
+  coordinate is checked independently — but is an author-error surface, not
+  covered by the HC-4 unrepresentability claim. (Audit 2026-06-22.)
+
+== History
+
+Superseded by R-2026-07-07 (ADR 0004) where they disagree. The pre-ratification
+theorems are retained in their files under provenance notes and remain true of
+the v0.1 carrier.
+
+*2026-06-22.* First verified core (Idris2): L1, L2, decidability of ⊑,
+Veridicality Derivation, Honest Generation, ε honest and coherent. Soundness
+advance: ⊑ a preorder, `verdictSound`, `subSound`, `soundFromExact`,
+monotonicity for bond and merge. A machine-checked FINDING that strict L4 fails
+on the v0.1 fate coordinate (`fateL4MonotonicityFails`, since removed with the
+carrier it described) made L4 lax and blocked conservative grade soundness;
+both are resolved on the ratified carrier (L4 row above). O1 exhaustiveness and
+L4/L5 as standalone lemmas were listed open; both are now proved (O1-carrier,
+L4, L5 rows).
+
+*2026-06-23.* Grade-algebra boundary in Lean (`GradeBoundary.lean`:
+`grade_mul_not_comm`, `grade_conical`, `grade_not_leftCancel`,
+`honest_fidelity_cancel`, `fidelity_unknown_not_cancel`,
+`fidelity_total_honest_not_cancel`, `dropped_absorbing`) and Theorem B in Agda
+(Targets 1, 2, 4 proved; Target 3 partial). The v0.1 carrier's ▷ was shown not
+commutative, symmetric cut impossible, and tier preservation closure rather than
+a homomorphism; the first two were artefacts of the clause (A1) removed and the
+third survives (C3 row). CO-1 was named the central open problem and recorded as
+additionally gated by the limit-carrier question O4, which ADR 0004 resolved.
+Documentation gaps on the v0.1 fate and bond tables and on tier-2 witnesses were
+recorded; the tables are complete in spec v0.2 §3 and the witnesses are
+`TierTwoComplete.lean`.
+
+*2026-06-29.* Tropical factorisation probe on the v0.1 carrier
+(`GradeFactorisation.lean`: `forced_collapse_general`, `forced_collapse_grade`):
+a homomorphism onto the commutative tropical carrier existed but every such map
+was forced to identify `Dropped` with `Falsified`. Re-run on the ratified
+carrier the verdict is (B′) sighted (Factorisation row above). The probe was and
+is a precondition, not a recursion result.

-= Tropical Factorisation Probe
-
-A dynamics-free, purely algebraic probe: *does the trope grade admit a homomorphic
-projection onto a commutative tropical cost, with all non-commutativity confined to the
-complement?* Source: `verification/proofs/lean4/grade-factorisation/`; full write-up:
-`verification/proofs/lean4/grade-factorisation/REPORT.adoc`.
-
-== Verdict — (B) FACTORS but VERIDICALITY-BLIND
-
-A *nontrivial* monoid homomorphism `π : (Grade, ▷, ε) → (Δ, +, Q 0)` onto the
-commutative tropical fidelity carrier `Δ = WithTop (WithTop ℕ)` *exists* — but *every*
-multiplicative map from `Fate` (and from `Grade`) into *any* commutative monoid is
-*forced* to identify the honest `dropped` with the deceptive `falsified`. So the best
-case (A, veridicality-preserving) is *impossible*, and the dead case (C, no
-homomorphism) is *false*.
-
-The blindness is *co-located* with the non-commutativity: it is the *fate-axis*
-honest/deceptive distinction that collapses of necessity, because that coordinate has two
-disagreeing absorbing heads. The *commutative* `Bond`/`Merge` coordinates carry no such
-obstruction — their deceptions stay tropically separable.
-
-== What is proved (Lean 4 + Mathlib; sorry-free; `propext`/`Quot.sound` only)
-
-[cols="1,3",options="header"]
-|===
-| Theorem | Statement
-| `pi_hom`, `pi_one`, `piHom` | `π` is a monoid homomorphism `Grade →* Multiplicative Δ`.
-| `pi_nontrivial`, `pi_surjective` | `π` separates attenuation levels and is onto `Δ` (not the trivial collapse).
-| `phiV_not_hom`, `piV_not_hom` | The veridicality-faithful candidate is *not* a homomorphism — breaker at `dropped ▷ falsified` (`total ≠ total + unknown = unknown`).
-| `forced_collapse_general`, `forced_collapse_grade` | *(axiom-free)* every multiplicative map into any commutative monoid identifies `dropped`/`falsified`.
-| `no_veridicality_faithful_hom` | Outcome (A) is impossible.
-| `psiBond_hom`, `psiBond_separates_honest_deceptive` | Bond deception *is* tropically separable — the loss is fate-specific.
-| `pi_blind_to_noncomm`, `grade_F2_noncomm`, `pi_collapses_F2` | `π` is blind to all non-commutativity; F2 confined to the complement.
-|===
-
-== Necessary-not-sufficient (read this)
-
-A positive result means *only* "the commutative cost-quotient EXISTS — the tropical
-route is NOT EXCLUDED, precondition met." It does *not* mean "tropical solves recursion."
-Whether a fixpoint's grade actually lives in the commutative part needs an operational
-model (*CO-1*, issue #10, gated by *O4*, issue #12) and stays parked. This probe can only
-kill the tropical route or fail to kill it; it cannot confirm it. The fixpoint is *not*
-solved, handled, or addressed by this work.

-== Reproduce

-[source,sh]
-----
-cd verification/proofs/lean4/grade-factorisation
-just build      # green; imports grade-boundary, reuses the pinned Mathlib build
-just falsify    # sorry-free, axiom-clean; both falsifier witnesses live
-just verdict    # names the load-bearing theorems

-
-== Next stage
-
-Issue #10 (CO-1 — operational model for `fix`/lfp), itself gated by issue #12 (O4 — the
-limit carrier).

-= The Trope-Particularity Calculus — v0.2 grade-algebra addendum (proved obligations)

-[abstract]
-This is a *draft addendum* to the trope-particularity calculus v0.1
-(`spec/calculus.adoc`, `:revnumber: 0.1`). It records, as dated normative
-obligations, four facts about the grade algebra that are now *machine-proved* in
-the Lean 4 + Mathlib development at `verification/proofs/lean4/grade-boundary/`
-(sorry-free; `#print axioms` = `propext`/`Quot.sound` only). The work here is
-*documentation only*: the algebra is already established; this document lifts it
-into normative spec text and binds each new obligation to its governing theorem.
-It does *not* edit v0.1 — it is written as a separate file precisely so the merge
-step can diff it against v0.1 — and it neither re-derives the theorems nor reopens
-the proved algebra; it binds each fact to its Lean name. v0.1's open obligation
-*O1* (completeness of the seven
-effects) is untouched and remains open throughout.
-
-The key words *MUST*, *MUST NOT*, *SHALL*, *SHALL NOT*, *SHOULD*, *MAY*, and
-*OPTIONAL* are to be interpreted as in RFC 2119/8174.
-
-toc::[]
-
-== Provenance, and what is being recorded (invent nothing)
-
-The four obligations below are *not* new claims. Each is a lift, in substance, of a
-green theorem from the grade-boundary harness, which is itself the single source
-of truth for the algebra. The carrier the theorems range over is, exactly:
-
-* fidelity `Delta = WithTop (WithTop ℕ)` (`dplus = (+)`, unit `Q 0 = 0`);
-* `Fate = Present | Atten Delta | Predicated | Dropped | Falsified`;
-* `Bond = Intact | Withheld | Severed | Misbound`;
-* `Merge = Single | Fused | Conflated`;
-* `Grade` = the flat record `Fate⁴ × Bond × Merge`, with *independent* fields.
-
-[IMPORTANT]
-.Two firewalls carried forward in substance from the harness, not to be laundered
-====
-. *No Frobenius / cancellative / conical framing exists in v0.1.* A grep of
-`calculus.adoc` finds none (its only near-hit, *O3*, is the unrelated
-produce/demand *adjunction* conjecture). The obligations below are therefore *new
-recordings of proved structure*, not transcriptions of existing v0.1 prose.
-
-. *"CF" (cancellative + conical ⇒ a lossless special-Frobenius split/merge) is
-refuted as universal*, and this document MUST NOT be read as reinstating it. It is
-ruled out twice over: by left-absorption of the deceptive bottoms
-(R-2026-06-23-03, *L5*, `grade_not_leftCancel`) and, independently, by
-non-commutativity of the full operation (R-2026-06-23-01, `grade_mul_not_comm`).
-What survives CF's refutation is *cancellation on the finite-fidelity core*
-(R-2026-06-23-03) — that algebraic fact alone, and no splitting or merging law,
-global or core-local.
-====
-
-=== Existing numbering recorded (the non-collision basis)
-
-So that the new ids are demonstrably consistent and non-colliding, v0.1's scheme
-is recorded here as it stands at the time of writing:
-
-[cols="1,3",options="header"]
-|===
-| Namespace (v0.1 / siblings) | Meaning, and its status under this addendum
-
-| `L1`–`L5` (v0.1 §4) | The composition laws. *Untouched.* `L5` is *constrained and
-  sharpened* by R-2026-06-23-03 (this addendum's §4), not replaced.
-| `O1`–`O4` (v0.1 §10) | The open obligations/falsifiers. *Untouched and still open*;
-  `O1` (seven-effects completeness) in particular is out of scope here.
-| `R-2026-06-22` (v0.1 §6.1) | The sole v0.1 decision-log id (the conflation-as-fault
-  decision). The `R-YYYY-MM-DD` shape is reused below.
-| `HC-*`, `L-*` | Reserved by the grade-boundary README for the *separate Agda*
-  development (Honest Generation; Veridicality). *Not touched, not collided with.*
-|===
-
-New obligations take the form *`R-2026-06-23-NN`*: the same `R-YYYY-MM-DD`
-decision-log prefix as `R-2026-06-22`, with a two-digit sequence suffix that
-extends the one-entry-per-date convention to carry several same-date records.
-This collides with none of `L\d`, `O\d`, `R-2026-06-22`, `HC-*`, or `L-*`.
-
-[NOTE]
-====
-*Source-of-truth toolchain.* All five primary governing theorems (`instMonoid`,
-`grade_mul_not_comm`, `grade_conical`, `grade_not_leftCancel`,
-`honest_fidelity_cancel`) are discharged under Lean `v4.16.0` + Mathlib `v4.16.0`,
-sorry-free, with `#print axioms` reporting `propext`/`Quot.sound` only — no
-`sorryAx`, no user `axiom`, no `native_decide`. The R-id ↔ theorem table in §7
-below (where one R-id binds a pair) is the claims-match-proofs contract; it is the
-artifact the merge step keys on.
-====
-
-== R-2026-06-23-01 — the grade is a *non-commutative* product monoid
-
-[cols="1,4",options="header"]
-|===
-| ID | Obligation (normative)
-
-| *R-2026-06-23-01* | The grade carrier under composition stem:[\triangleright] is
-a *monoid*, formed as the *componentwise product* of its coordinate monoids
-(`Fate⁴ × Bond × Merge`); this is the *degenerate-to-product* structure, confirmed
-constructively (`instMonoid`). That product *MUST NOT* be assumed commutative: it
-is *non-commutative* (`grade_mul_not_comm`). Consequently any algebraic model of
-the operation stem:[\triangleright] *MUST* treat it as order-sensitive, and
-*SHALL NOT* assume `CommMonoid`, `AddCommMonoid`, or special-Frobenius structure
-for it. The non-commutativity is a property of the *full* operation, witnessed by
-elements outside the cancellative core (the disagreeing heads `Dropped` and
-`Falsified`); special-Frobenius is moreover unavailable across the honest region,
-whose non-cancellative honest-but-lossy tier obstructs its comonoid leg
-(R-2026-06-23-03).
-|===
-
-This records v0.1 *L1–L2* (monoid) at full strength while adding the order
-discipline v0.1 left implicit. The witness to non-commutativity is intrinsic to
-the `Fate` coordinate: it carries *two* distinct left-absorbing heads, `Dropped`
-and `Falsified`, which disagree (`Dropped ▷ Falsified = Dropped` but
-`Falsified ▷ Dropped = Falsified`), so swapping operands changes the result
-(`Fate.not_comm`, lifted to the `fQuality` field by `grade_mul_not_comm`).
-
-[IMPORTANT]
-====
-*Order matters, not merely grade-sum.* Because stem:[\triangleright] is
-non-commutative, two effect sequences with the *same multiset* of per-step grades
-*MAY* compose to *different* total grades. A checker, an IR producer, or any
-optimiser *MUST NOT* reorder effect edges (v0.1 §9) under the assumption that
-composition is symmetric. This is the precise sense in which special-Frobenius —
-which presupposes a commutative comonoid/monoid interaction — is *unavailable*:
-the obstruction is structural (order-sensitivity), independent of, and additional
-to, the cancellation obstruction of R-2026-06-23-03.
-====
-
-== R-2026-06-23-02 — conicality of the full grade
-
-[cols="1,4",options="header"]
-|===
-| ID | Obligation (normative)
-
-| *R-2026-06-23-02* | The full grade carrier is *conical*: for all grades
-stem:[a, b], if stem:[a \triangleright b = \varepsilon] then stem:[a = \varepsilon]
-*and* stem:[b = \varepsilon] (`grade_conical`). The unit grade stem:[\varepsilon]
-(full presence, intact bond, single merge) *MUST NOT* be treated as reachable
-under composition by any pair other than stem:[\varepsilon \triangleright \varepsilon].
-|===
-
-Conicality holds on the *entire* carrier (not only the core), and is proved
-fieldwise from per-coordinate conicality (`Fate.conical`, `Bond.conical`,
-`Merge.conical`). Operationally: no amount of loss can be *manufactured from* the
-unit, and the loss-free state cannot be *re-attained* except from itself. A
-verdict engine *MAY* rely on this — a final grade of stem:[\varepsilon]
-witnesses a genuinely loss-free pipeline, never an accidental cancellation of
-losses against gains, because there are no gains.
-
-== R-2026-06-23-03 — the three-tier cancellation boundary (headline)
-
-[cols="1,4",options="header"]
-|===
-| ID | Obligation (normative)
-
-| *R-2026-06-23-03* | The carrier is stratified by cancellability into *three
-strict tiers*. Write stem:[\mathcal{C}] for the *cancellative core*,
-stem:[\mathcal{H}] for the *honest* region, and stem:[\mathcal{G}] for the *full*
-carrier. Then the inclusions are *strict*:
-stem:[\mathcal{C} \subsetneq \mathcal{H} \subsetneq \mathcal{G}]. *Cancellation
-holds ONLY on the finite-fidelity core stem:[\mathcal{C}]*
-(`honest_fidelity_cancel`), and *fails everywhere above it* — on the
-honest-but-lossy tier and on the deceptive tier alike; the full carrier is
-*non-left-cancellative* (`grade_not_leftCancel`). Accordingly, *should* a future
-revision introduce a lossless fractional split, rejoin, or routing operator (none
-exists today — see OPEN-A), that operator *MUST* be licensed *ONLY* on
-stem:[\mathcal{C}], the sole region carrying the cancellation it would rely on;
-on stem:[\mathcal{H} \setminus \mathcal{C}] and on
-stem:[\mathcal{G} \setminus \mathcal{H}] it *MUST* be treated as lossy and
-irreversible, and *MUST NOT* be presented as recoverable.

-|===
-| Tier | Region | Inhabitants and cancellation status
-
-| *1* | *Cancellative core* stem:[\mathcal{C}]
-| The finite-fidelity region — `Atten(Q n)` with stem:[n \in \mathbb{N}], where
-  `Delta.Q` embeds stem:[(\mathbb{N}, +, 0)] injectively and additively — together
-  with the coordinate units (`Present`, `Intact`, `Single`). *Cancellation holds*
-  here and *only* here (`honest_fidelity_cancel`).
-
-| *2* | *Honest-but-lossy* stem:[\mathcal{H} \setminus \mathcal{C}]
-| `Dropped`, `Predicated`, `Severed`, `Withheld`, `Fused`, and `Total` (honest
-  stem:[\infty]). These are *honest* — they tell no lie about what was lost — yet
-  they are *non-cancellative* (`Fate.predicated_honest_not_cancel`,
-  `Bond.severed_honest_not_cancel`, `fidelity_total_honest_not_cancel`; `Withheld`
-  and `Fused` belong here by the carrier's order structure but carry no individual
-  witness yet — OPEN-C). Honest loss is still loss: it cannot be undone.
-
-| *3* | *Deceptive, absorbing bottoms* stem:[\mathcal{G} \setminus \mathcal{H}]
-| `Falsified` (fate), `Misbound` (bond), `Conflated` (merge), and `Unknown`
-  (fidelity). Each is a *left zero* (`Fate.falsified_absorbing`,
-  `Bond.misbound_absorbing`, `Merge.conflated_absorbing`,
-  `Delta.unknown_absorbing`): it absorbs everything composed after it, so it
-  cannot be cancelled back out. This is *L5*.

-
-[WARNING]
-.Two strict inclusions, two distinct witnesses — do not collapse them
-====
-The boundary is *three-tier, not two-tier*: the non-cancellative set is
-*strictly larger* than the deceptive set.
-
-. stem:[\mathcal{C} \subsetneq \mathcal{H}] is witnessed by an *honest* element
-that nonetheless fails to cancel — e.g. `Total`, `Severed`, or `Predicated`
-(`fidelity_total_honest_not_cancel`, `Bond.severed_honest_not_cancel`,
-`Fate.predicated_honest_not_cancel`). "Honest" does *not* imply "cancellative".
-
-. stem:[\mathcal{H} \subsetneq \mathcal{G}] is witnessed by a *deceptive* element
-— e.g. `Falsified` — at which left-cancellation fails outright
-(`grade_not_leftCancel`).
-
-Conflating these two would mis-state the algebra: it would either (wrongly) license
-splitting on honest-but-lossy elements, or (wrongly) brand honest loss as
-deception. Both are forbidden.
-====
-
-[IMPORTANT]
-.The split / rejoin / routing constraint is a constraint-in-advance
-====
-The licensing constraint above is the frozen consequence both the calculus and its
-proof harness must respect: any fractional split / rejoin / routing is licensed
-*only* on the cancellative core stem:[\mathcal{C}] (tier 1), is order-sensitive
-(F2 / R-2026-06-23-01), and is *forbidden* on tiers 2 and 3. The order-sensitivity
-attaches to the routing *operation*, not to the internal composition of core
-grades: within stem:[\mathcal{C}] the grade product reduces to fidelity addition
-(`Delta.Q_add`), which is commutative *and* cancellative, so the core licenses
-*both* losslessness and commutative reassembly. It is the operation's general form
-— which may move grades between coordinates and tiers — that the order discipline
-of R-2026-06-23-01 governs.
-
-This addendum *defines no split / rejoin / routing operator* — none exists in
-v0.1. The obligation here *constrains in advance* any such operator a future
-revision may introduce; the operator itself is listed as OPEN-A in §8.

-== R-2026-06-23-04 — partition correction: `Dropped` and `Total` are *honest*
-
-[cols="1,4",options="header"]
-|===
-| ID | Correction (normative, dated for the decision-log)
-
-| *R-2026-06-23-04* | `Dropped` and `Total` *MUST* be classified as *honest*, not
-deceptive. `Dropped` is *honest withholding* — a field withheld entirely, the
-clean omission whose *deceptive dual* is the distinct fate `Falsified`. `Total`
-is the *honest* stem:[\infty] — total quantified loss — whose deceptive
-counterpart is the fidelity bottom `Unknown` (loss of *unknown* amount).
-Documentation, taxonomy tables, and tooling *MUST NOT* enumerate `Dropped` or
-`Total` in the deceptive tier (tier 3 of R-2026-06-23-03).
-|===
-
-This correction is recorded explicitly because it *contradicts informal
-phrasings* that treat any absorbing or bottom-like element as deceptive. Both
-`Dropped` and `Total` are *absorbing* in their coordinate yet *truthful*:
-`Dropped` is left-absorbing on `Fate` (`Fate.dropped_absorbing`) while remaining
-an honest omission; `Total` absorbs finite fidelity (`Delta.total_add_Q`) and is
-itself absorbed only by the deceptive `Unknown` (`Delta.total_add_unknown`),
-yet asserts no falsehood. The distinction *absorbing-but-honest* versus
-*absorbing-and-deceptive* is the whole reason the boundary is three-tier
-(R-2026-06-23-03): it is *precisely* because `Dropped`, `Total`, `Severed`, and
-`Predicated` are honest-yet-non-cancellative that "cancellation fails stem:[\iff]
-deception" is *false*.
-
-[NOTE]
-====
-*Carrier reconciliation.* The proved `Fate` coordinate has *five* inhabitants —
-it includes `Falsified`, the deceptive fate-bottom dual to honest `Dropped`. v0.1
-§3.1's fate table lists only *four* (`Present`, `Attenuated(δ)`, `Predicated(P)`,
-`Dropped`) and predates `Falsified`. This addendum records `Falsified` as
-established by the carrier; whether v0.1 §3.1 should be amended to introduce it is
-a documentation-reconciliation decision for the merge author, logged as OPEN-B
-(§8). Nothing here edits v0.1 §3.1.
-====
-
-== Relationship to the v0.1 obligations
-
-*R-2026-06-23-03 constrains, and does not replace, L5.* v0.1's *L5* ("conflation
-infectiousness": once the merge coordinate is `Conflated`, no composition restores
-`Fused` or `Single`) stands unchanged. R-2026-06-23-03 makes L5's irreversibility
-*precise* — it is *left-absorption of the deceptive bottom* — and *generalises* it
-from the merge coordinate alone to *every* coordinate's deceptive bottom
-(`Falsified`, `Misbound`, `Conflated`, `Unknown`), with the full-carrier
-consequence `grade_not_leftCancel`. Read together: v0.1's L5 is the merge-coordinate
-instance of the general left-absorption fact that R-2026-06-23-03 records.
-
-*L1–L3 are reinforced; the L4 relationship is sharpened.* R-2026-06-23-01 records
-the L1–L2 monoid at full strength and adds the order discipline (non-commutativity)
-that L1's associativity alone does not capture. L3 (bottom-absorption) is the
-per-coordinate left-absorption that R-2026-06-23-03 makes precise. The tier
-stratification, however, is a *cancellation* property and does *not* presuppose the
-retention order: strict *L4 monotonicity is only lax — it fails on the fate
-coordinate* (machine-proved downstream as `fate-L4-fails`, the same F2×F4
-phenomenon), so tier-preservation is set-membership *closure*, not an
-order-homomorphism, and v0.1 §7's appeal to *strict* L4 to justify the `fix` grade
-needs the lax/closure route (part of CO-1, below).
-
-*O1 is untouched and remains open.* v0.1's *O1* — that the seven effects are
-*exhaustive* — is a separate completeness question and is *not* addressed,
-advanced, or closed here. The algebraic facts recorded in this addendum concern
-the *structure of the grade monoid*, not the *enumeration of the effects that
-populate it*; the two are orthogonal. O2–O4 are likewise untouched.
-

-(the upper strict inclusion / L5) and `honest_fidelity_cancel` (the core) — with

-
-== OPEN, for author review
-
-The following surfaced while authoring and are *genuine gaps* that F1–F4 and the
-partition correction do *not* settle. In line with the brief, they are *recorded,
-not filled*.
-
-* *OPEN-A — the split / rejoin / routing operator is referenced but undefined.*
-  R-2026-06-23-03 (and the frozen consequence it records) governs the
-  cancellability of *fractional split / rejoin / routing*, yet no such operator is
-  defined in v0.1 or in the grade-boundary harness. The obligation constrains an
-  operation that does not yet exist. Whether to introduce it — and if so, with what
-  typing rule — is for author review; until then R-2026-06-23-03 stands as a
-  *constraint-in-advance*. _Now elevated:_ integrating this addendum with the Agda
-  metatheory (Theorem B) showed OPEN-A and Theorem B's unreached `fix`/lfp
-  subject-reduction case to be *one and the same* underspecification — the calculus
-  defines no operational (reduction) model for its grade-routing / iterating
-  constructs beyond the β/let core — now tracked as the repository's central open
-  problem *CO-1* (itself gated by v0.1's O4, the limit carrier). See
-  `verification/proofs/INTEGRATION-REPORT.adoc` §4 and ADR 0003.
-
-* *OPEN-B — `Falsified` is absent from v0.1 §3.1.* The proved `Fate` coordinate is
-  five-ary, but v0.1 §3.1's fate table lists four inhabitants and does not mention
-  `Falsified` (the deceptive dual of `Dropped`). This addendum records `Falsified`
-  as carrier-established; whether the eventual v0.2 should amend v0.1 §3.1 to
-  introduce it normatively — and how that interacts with the v0.1 §6.1
-  conflation-as-fault story
-  for the *fate* coordinate — is a documentation-reconciliation decision, not one
-  fixed by F1–F4.
-
-* *OPEN-B′ — `Misbound` is absent from v0.1 §3.2.* Surfaced when this addendum was
-  swept against the Agda metatheory (Theorem B): the bond coordinate carries a
-  *deceptive dual* `Misbound` — bond's order-bottom, the dual of honest `Severed` —
-  exactly as the fate coordinate carries `Falsified`, yet v0.1 §3.2 lists only three
-  bonds (`Intact`, `Withheld`, `Severed`) and omits it. This is the precise analogue
-  of OPEN-B for the bond coordinate; merge's deceptive bottom `Conflated` is, by
-  contrast, already present in v0.1 §3.3. The Idris2 core both enumerates the three
-  deceptive duals (`Trope.Veridicality.deceptiveDuals` = `(Falsified, Misbound,
-  Conflated)`) and proves each the *unique* deceptive inhabitant of its coordinate
-  (`Trope.Veridicality.bondDeceptiveUnique` for `Misbound`). Whether to amend v0.1
-  §3.2 is the same documentation-reconciliation decision as OPEN-B, to be taken
-  together with it.
-
-* *OPEN-C — tier-2 membership is recorded, not exhaustively proved.* The harness
-  proves *representative* honest-but-lossy elements non-cancellative (`Predicated`,
-  `Severed`, `Total`). That `Withheld` and `Fused` also sit in tier 2 (honest,
-  non-cancellative) is asserted here from the carrier's order structure but is not
-  individually witnessed by a named theorem in the current harness. Whether to add
-  those witnesses, or to prove tier-2 membership uniformly, is for author review.

+The vocabulary (`trope-particularity-workbench`) names *nine* effects. The
+calculus realises them as follows. An *atom* is a grade that differs from
+stem:[\varepsilon] in exactly one slot; atoms come in nine families, one per
+non-unit coordinate value kind. *Every pre-ratification `Grade` factors as a
+▷-product of its single-slot projections* (`EffectAtoms.lean`, importing the

+`family_realized`, `families_disjoint`). The same factorisation is proved on
+the ratified carrier this calculus actually uses (`EffectAtomsRatified.lean`:
+`GradeR.atom_factorization`); the nine-family classification classifies
+*coordinate values*, which ratification did not change, so it carries over
+unchanged. O1's carrier-relative half is therefore PROVED for `GradeR` (§10);
+what remains open is O1-coord, the adequacy of the coordinates themselves.

+Two structure theorems fix this table rather than leaving it a list:
+
+* *Honest Generation.* The five atomic moves `attenuate`, `predicate`, `drop`,
+  `sever`, `fuse` together with stem:[\varepsilon] generate exactly the honest
+  fragment of each coordinate, and never produce a deceptive dual
+  (`Trope.Generation.{genFate,genBond,genMerge}`; Agda `TB.Honest.genFate` etc.,
+  `honest-closed-▷`).
+* *Veridicality Derivation.* The deceptive fragment has exactly three
+  inhabitants, one per coordinate kind — `Falsified`, `Misbound`, `Conflated` —
+  each the unique deceptive element of its coordinate
+  (`Trope.Veridicality.{fate,bond,merge}DeceptiveUnique`; Agda
+  `TB.Honest.{fate,bond,merge}DeceptiveUnique`). One cannot deceptively assert
+  a loss; the only deceptions are false value, false bearer, false singleness.
+
+[NOTE]
+====
+*Two senses of "deceptive", kept apart.* *Grade-deceptive* is the
+veridicality sense above: `Falsified`, `Misbound`, `Conflated` — grades that
+claim a faithfulness they do not have. The fidelity carrier Δ has its own
+*tier* classification (`TB.Tier.dTier`), under which `⊤` (`Unknown`, loss of
+unknown amount) is the *tier-deceptive* element: worst-case opacity about
+*how much* was lost. These are different claims. `Attenuated(⊤)` is
+grade-*honest* — it declares its ignorance rather than asserting a bound it
+does not have — and tier-deceptive. Unqualified "deceptive" in this document
+means grade-deceptive; the fidelity sense is always written
+*tier-deceptive*. The distinction is load-bearing at L3 (§4.1): no-laundering
+quantifies over grade-deception, while `Dropped` absorbing `Attenuated(⊤)`
+is an honest absorber subsuming admitted ignorance — retention only
+decreases (L4), and no false claim is erased, because none was made.
+====
+
+So "seven effects" (six writable plus the conflation fault), which earlier
+versions of this document used, and "nine effects" (the vocabulary) describe the
+same carrier: nine atom families, of which six are writable surface effects
+and three are faults. This document uses *nine* throughout.

The *honest* bottoms (`Dropped`, `Severed`) absorb within the honest fragment. Fidelity's `Unknown` (`⊤`) is a two-sided zero of the *fidelity* composition (Δ-addition) only, and is *tier*-deceptive, not grade-deceptive (§3.5 note): `Attenuated(⊤)` is honest, so its absorption by `Dropped` at the fate coordinate launders nothing — total admitted loss subsumes unquantified admitted loss. What A1 forbids is exactly the deceptive case, e.g. `Dropped ▷ Falsified = Falsified`, never `Dropped`.

New at v0.2: on this ratified carrier the grade monoid is *commutative* (Lean `GradeR.instCommMonoid`, `FateA.comp_comm`; Agda `grade-comm`). These proofs carry no predicate or fusion labels and assert no equality between labelled grades. The v0.1 non-commutativity (`GradeBoundary.grade_mul_not_comm`) was an artefact of the clause (A1) removed.

+|===
+| ID | Fact
+
+| *C1 (conicality)* | stem:[g_1 \triangleright g_2 = \varepsilon \Rightarrow g_1 = g_2 = \varepsilon]: nothing lossy composes back to no-loss. (Lean `GradeR.conical`, `FateA.conical`; Agda `grade-conical`.)
+| *C2 (the cancellation boundary)* | The boundary is carrier-relative, and both carriers matter. On the *unquotiented* carrier, an element of the grade monoid is left-cancellative *iff* it is stem:[\varepsilon] — finite attenuation fails to cancel there, correctly, because `Attenuated(Q 0)` is a distinct element from `Present` and the two collide (Lean `GradeR.gradeR_leftCancel_iff`; historical carrier: `Grade.grade_leftCancel_iff`; per-element witnesses in `TierTwoComplete.lean`). On the *A3-normalized* carrier — the one IR ingest actually stores, where `Attenuated(Q 0)` is rewritten to `Present` — that collision disappears and finite attenuation *is* left-cancellative on the fate coordinate (Lean `FateA.atten_cancel_on_normalForms`; Δ-level: Agda `TB.Tier.Q-cancelʳ`), so cancellation holds exactly on the finite-fidelity core stem:[\mathcal{C}] (fates in `Q ℕ ≅ (ℕ,+,0)`, `bond = Intact`, `merge = Single`) and fails on the honest-but-lossy and deceptive tiers alike (Agda's six `*-not-cancel` lemmas). C1/C2 in this section quantify over the normalized carrier unless stated. Consequence: a lossless *split / rejoin* can be cancellative only inside stem:[\mathcal{C}]; any such operator (§10, CO-1) MUST be stated against this boundary.
+| *C3 (partition)* | `Dropped`, `Total` (stem:[\infty]), `Severed`, `Predicated`, `Withheld`, `Fused` and `Attenuated(⊤)` (`Unknown`) are *honest* non-cancellative elements; `Falsified`, `Misbound` and `Conflated` are the *deceptive* ones. `Unknown` is deceptive only in the fidelity-*tier* sense (§3.5 note): it asserts no bound, so it makes no false claim. Absorbing is not the same as lying, and neither is admitted ignorance. (Lean `dropped_absorbing`, `fidelity_total_honest_not_cancel`; Agda `TB.Tier` classifiers.) Tier preservation under composition is *closure*, not a homomorphism: `tierOf (g ▷ h) = tierOf g ⊓ tierOf h` is false on fate even on the ratified carrier (`TB.Tier.fate-tier-meet-hom-fails`).

+
+=== The tropical factorisation
+
+A nontrivial monoid homomorphism stem:[\pi_R : (\mathrm{GradeR}, \triangleright, \varepsilon) \to (\Delta, +, Q\,0)]
+onto the commutative tropical fidelity carrier exists and is
+*veridicality-sighted*: `Dropped ↦ ∞` and `Falsified ↦ ⊤`, so the hom is blind
+to *which honest* absorber acted but not to *whether the absorber was honest*
+(`GradeFactorisationR.lean`: `piR_hom`, `piR_nontrivial`, `piR_surjective`,
+`piR_sighted`). The naive hom that reads the attenuation payload off verbatim is
+*not* a homomorphism on the ratified carrier (`phiId_not_hom`); the repair,
+`GradeFactorisationR.squash`, maps the tier-deceptive payload `Unknown`
+(`Delta.unknown`, `⊤`) to `Total` (`Delta.total`, or `∞`) inside attenuation
+(`sighted_forces_squash` proves every veridicality-sighted hom must give up
+that separation). On the v0.1 carrier every such hom was
+forced to collapse `Dropped` with `Falsified` (`GradeFactorisation.lean`,
+`forced_collapse_general`) — a theorem about the pre-ratification carrier only.
+This factorisation is a *precondition*, not a recursion result: whether a
+fixpoint's grade lives in the commutative part is a CO-1 question (§10).

+[NOTE]
+====
+*Historical report (2026-06-29).* This reconciles the two proof streams against
+the *pre-ratification* carrier. It is kept unchanged as the record of that
+integration. Since then: ADR 0004 (R-2026-07-07) amended the carrier — the
+non-commutativity, the lax L4 and OPEN-B/B′/C below are all resolved on the
+ratified carrier — and the v0.2 addendum it cites (`spec/calculus-v0.2-draft.adoc`)
+was folded into `spec/calculus.adoc` v0.2 on 2026-10-13. Current status lives in
+`docs/status/PROOF-STATUS.adoc` and `AFFIRMATION.adoc`.
+====
+
 [abstract]
 This report integrates two independently-produced work-streams into one coherent
 contribution, each measured against the same authoritative algebra:

+# O1 relative to the carrier, on the RATIFIED carrier `GradeR`
+
+`EffectAtoms.lean` proves the carrier-relative half of **O1** — every grade is
+the ▷-product of its six single-slot projections (`Grade.atom_factorization`),
+with the projections classified into the nine atom families — over the
+historical, pre-ratification `Grade`. That left an honest gap: the theorem
+cited for O1-carrier was about a carrier the project no longer uses.
+
+This module closes that gap. It states and proves the same factorisation over
+`GradeR` (`GradeRatified.lean`), whose fate slots compose by the ratified
+`FateA.comp` (ADR 0004, R-2026-07-07). The nine-family classification itself
+(`Trope.fateFamily` / `bondFamily` / `mergeFamily`, `nine_families`,
+`family_realized`, `families_disjoint`) is a classification of *coordinate
+values*, and ratification changed the fate composition and order — not the
+coordinate value sets — so it carries over unchanged; only the factorisation,
+which is about composition, needs re-proving. The proof is the historical one
+with the fate-slot unit laws swapped from `Fate.present_mul`/`mul_present` to
+`FateA.one_comp`/`comp_one`.
+
+What remains open is unchanged: **O1-coord**, whether the three coordinates
+themselves are metaphysically adequate. That is a claim about the world, not
+the algebra, and no theorem here touches it.

+The trope-particularity checker: a portable IR + checker for the honest/deceptive
+**trope grade**, backed by machine-checked proofs across Idris2, Lean 4 + Mathlib, and
+Agda.
+
+## Verification streams
+
+- **Verified core** (Idris2) — `verification/proofs/idris2/`: the grade algebra reused by
+  the executable checker; the thing that runs is the thing that is proved.
+- **Grade-algebra ground truth** (Lean 4 + Mathlib) — `verification/proofs/lean4/grade-boundary/`:
+  the ratified commutative `GradeR` monoid (the historical carrier is non-commutative),
+  full-carrier conicality, and the three-tier strict honest/deceptive cancellation
+  boundary. Sorry-free; axioms `propext`/`Classical.choice`/`Quot.sound` only.
+- **Tropical factorisation probe** (Lean 4 + Mathlib) — `verification/proofs/lean4/grade-factorisation/`:
+  see [Tropical Factorisation Probe](Tropical-Factorisation-Probe.md). Ratified-carrier verdict
+  *(B′) FACTORS AND VERIDICALITY-SIGHTED*; historical (B) applies to the
+  pre-ratification carrier. A precondition only.
+- **Calculus metatheory — Theorem B** (Agda `--safe --without-K`) — `verification/proofs/agda/theorem-b/`:
+  intrinsic graded calculus, value substitution, β/let subject reduction, Honest
+  Generation. Zero postulates. (`fix`/lfp open — CO-1.)
+
+## The central open problem
+
+**CO-1** — an operational model for `fix`/routing dynamics has been designed, but
+not yet mechanised; full subject reduction remains open (issue #10). **O4**, the
+limit-carrier question (issue #12), is resolved under the ratified carrier repair
+and no longer gates CO-1. See `spec/notes/2026-07-07-co1-operational-model.adoc`
+and `spec/notes/2026-07-07-l4-boundary-and-atoms.adoc` §4.

+
+## Honesty
+
+Status is ground-truthed by running the tools, not by reading prose. See

+# Tropical Factorisation Probe
+
+A dynamics-free, purely algebraic probe: *does the trope grade admit a homomorphic
+projection onto a commutative tropical cost, with all non-commutativity confined to the
+complement?* Source: `verification/proofs/lean4/grade-factorisation/`; full write-up:
+`verification/proofs/lean4/grade-factorisation/REPORT.adoc`.
+
+## Verdict — (B′) FACTORS AND VERIDICALITY-SIGHTED (ratified carrier)
+
+Under the ratified carrier (R-2026-07-07, ADR 0004 A1/A2), a nontrivial, surjective
+monoid homomorphism `πR : (GradeR, ▷, ε) → (Δ, +, Q 0)` exists (`piR_hom`, `piR_one`,
+`piRHom`, `piR_nontrivial`, `piR_surjective`). It distinguishes honest `Dropped`
+from deceptive `Falsified`: `∞` (`total`) versus `⊤` (`unknown`), proved by
+`phiR_sighted` and `piR_sighted` in `GradeFactorisationR.lean`.
+
+This sightedness has a trade-off: attenuation payload `⊤` is squashed to `∞`, so
+`Atten ∞` and `Atten ⊤` share a cost (`sighted_forces_squash`). `Predicated` and
+`Dropped` also share the honest total-loss cost (`phiR_collapses_predicated_dropped`).
+See the report's “Re-run under the ratified carrier” section for the full result.
+
+## Historical verdict — (B) FACTORS but VERIDICALITY-BLIND (pre-ratification)
+
+The following result applies only to the pre-ratification carrier, whose fate
+composition has `Dropped ▷ Falsified = Dropped` and `Falsified ▷ Dropped = Falsified`.
+The ratified carrier instead has `Dropped ▷ Falsified = Falsified`; the forced-collapse
+claim below does not apply to it.
+
+A **nontrivial** monoid homomorphism `π : (Grade, ▷, ε) → (Δ, +, Q 0)` onto the
+commutative tropical fidelity carrier `Δ = WithTop (WithTop ℕ)` **exists** — but **every**
+multiplicative map from `Fate` (and from `Grade`) into **any** commutative monoid is
+**forced** to identify the honest `dropped` with the deceptive `falsified`. So the best
+case (A, veridicality-preserving) is **impossible**, and the dead case (C, no
+homomorphism) is **false**.
+
+The blindness is **co-located** with the non-commutativity: it is the **fate-axis**
+honest/deceptive distinction that collapses of necessity, because that coordinate has two
+disagreeing absorbing heads. The **commutative** `Bond`/`Merge` coordinates carry no such
+obstruction — their deceptions stay tropically separable.
+
+## Historical proofs (Lean 4 + Mathlib; sorry-free; `propext`/`Quot.sound` only)
+
+| Theorem | Statement |
+| --- | --- |
+| `pi_hom`, `pi_one`, `piHom` | `π` is a monoid homomorphism `Grade →* Multiplicative Δ`. |
+| `pi_nontrivial`, `pi_surjective` | `π` separates attenuation levels and is onto `Δ` (not the trivial collapse). |
+| `phiV_not_hom`, `piV_not_hom` | The veridicality-faithful candidate is **not** a homomorphism — breaker at `dropped ▷ falsified` (`total ≠ total + unknown = unknown`). |
+| `forced_collapse_general`, `forced_collapse_grade` | **(axiom-free)** every multiplicative map into any commutative monoid identifies `dropped`/`falsified`. |
+| `no_veridicality_faithful_hom` | Outcome (A) is impossible. |
+| `psiBond_hom`, `psiBond_separates_honest_deceptive` | Bond deception **is** tropically separable — the loss is fate-specific. |
+| `pi_blind_to_noncomm`, `grade_F2_noncomm`, `pi_collapses_F2` | `π` is blind to all non-commutativity; F2 confined to the complement. |
+
+## Necessary-not-sufficient (read this)
+
+A positive result means **only** "the commutative cost-quotient EXISTS — the tropical
+route is NOT EXCLUDED, precondition met." It does **not** mean "tropical solves recursion."
+Whether a fixpoint's grade actually lives in the commutative part needs an operational
+model (**CO-1**, issue #10, gated by **O4**, issue #12) and stays parked. This probe can only
+kill the tropical route or fail to kill it; it cannot confirm it. The fixpoint is **not**
+solved, handled, or addressed by this work.
+
