Until S4 is green it is a + design conversation, not a code path. +``` + +**Do not skip to S3.** The MedCare and OpenProject transcodes both earned their +numbers by measuring at S1/S2 first (`99.6 %` recoverable, `98.4 %` recipe +coverage) — those figures are what made the later codegen defensible. + +## 3. The old/new SoA and `Va*` format question + +There are two independent axes here and conflating them is the failure mode. + +**Axis 1 — the physical row.** The V3 512-byte `NodeRow` (`16 | 16 | 480`) is +CANON and unchanged. What is V1-legacy is the *reading* of two fields: the +`NodeGuid` u24 tail (new mints go through the 4+12 content-blind facet) and the +`EdgeBlock`'s 12+4 carving (resolve `ClassView::edge_codec_flavor`). Neither +requires an `ENVELOPE_LAYOUT_VERSION` bump, and neither is something this +harvest emits. + +**Axis 2 — the `Va*` carrier family** (`Vsa16kF32` / `Vsa16kBF16` / `Vsa16kF16` +/ `Vsa16kI8` / `Binary16K`). These are *compute* formats, selected per workload, +not a schema. The relevant standing rulings: `Vsa16kF32` is deprecated **as a +cross-boundary carrier** (it never crosses a mailbox boundary), and VSA is +demoted to its `I-VSA-IDENTITIES` niche — lossless role superposition of +**identities**, `N ≤ √d/4 ≈ 32`, never of content or of quantized codes. + +**What that means for you concretely:** the R2IL harvest emits *neither*. It +emits flat facet-addressed rows and a residual ledger. If you find yourself +about to bundle R2IL facts into a `Va*` carrier, run the four +`I-VSA-IDENTITIES` tests first — in particular Test 0 (register laziness: does +this thing have a natural id? then use the id) and Test 1 (bundle size). R2IL +facts have natural ids (`FactId`, `InstId`, `ValueId`), so Test 0 short-circuits +and the answer is almost certainly "not a VSA workload". + +## 4. Additive export — the mechanics + +When you extend the export (and you will), obey these five: + +1. **Version the header, never the reader's assumptions.** Every row artifact + carries `#version N` and a `#schema` line naming its columns. Bump `N` when + you ADD; a reader that keys off `#schema` names needs no change at all. +2. **Append columns; never reorder or remove.** A column that becomes + meaningless gets an explicit empty value, not deletion — the same + RESERVE-DON'T-RECLAIM rule the node key follows. +3. **New enum variants are expected, not exceptional.** `ResidualReason` grows + as the furnace learns; a consumer must render an unknown reason as its raw + string and carry on. Never `match` exhaustively across a process boundary. +4. **Never widen a field to fit one outlier.** That is what route-local + overflow is for (`mint_factored`'s base-255 cascade; `MAX_SIBLINGS_PER_TIER + = 255` is a design smell, *not* a storage ceiling). One 900-way phi does not + get to change the ABI for everyone. +5. **A new pass gets a NEW release tag.** Harvest assets are immutable + evidence. Re-running and overwriting `r2il-harvest-pass1` in place destroys + the ability to diff pass N against pass N+1 — which is the whole point of + keeping the failing B2 run in history. + +## 5. What "without breaking existing" means in practice + +- **Generated code lands beside hand code, never inside it.** A `// @generated` + header and its own module. If a generated item must be specialised, the + specialisation lives in hand code that *calls* it. +- **The SPO projection stays optional and lossy.** `ModelGraph → expand() → + Vec` is a projection of *semantic* facts (calls, reads, writes). It is + not the behavioral roundtrip oracle and must never become the source you + reconstruct R2IL from. +- **Conservation is your regression test.** If a staged consumer starts + dropping facts, `harvested == classified + residual` with `dropped == 0` is + the invariant that catches it. Assert it in your own pipeline too, not just + in ours. +- **When the arm can't explain something, that is data.** Do not paper a gap + with a catch-all so your codegen compiles. A named residual with an address + is worth more than a generated stub that silently means nothing. + +## 6. Where things live + +- **Canonical bulk evidence:** GitHub Release `r2il-harvest-pass1` + (`r2il-pass1.ore.tsv.gz`, `r2il-convention.toml.gz`). +- **Scratch mirror + config backup:** `s3://$AWS_S3_BUCKET_NAME/r2il-arc/` + (`harvest/` and `config-backup//`), and this guide at + `r2il-arc/harvest/STAGED-CODEGEN-GUIDE.md`. The MedCare-rs backup is the one + thing NOT under `r2il-arc/` — it belongs to that repo and lives at + `MedCare-rs/harvest/2026-08-18/`, datestamped like the `bakes/` siblings + beside it. Credentials from `AWS_*` env only — the bucket is **shared** with + other work (`q2`, `MedCare-rs`, `OSM`, `ontologies`), so stay inside your own + prefix and never write at the root. +- **In-tree:** `.claude/harvest/r2il/` keeps the small readable artifacts; + the plan and impl spec are in `.claude/plans/`. diff --git a/.claude/harvest/r2il/TRIAGE-RESULT.md b/.claude/harvest/r2il/TRIAGE-RESULT.md new file mode 100644 index 00000000000000..76678752e7152c --- /dev/null +++ b/.claude/harvest/r2il/TRIAGE-RESULT.md @@ -0,0 +1,31 @@ +# R2IL pass-1 TRIAGE RESULT + +Caps in force: `R2IL_HARVEST_MAX_FUNCS=200`, `R2IL_HARVEST_MAX_SECTION_BYTES=262144` + +## Pre-registered bars (stated BEFORE the measured section below) + +- **B1 — conservation (absolute).** `dropped == 0` and `harvested == classified + residual`.

The furnace loop + +``` +mess → config DTO → proposer placement → residual DTO → next pass +``` + +Five moves, repeated until the slag pile stops shrinking: + +1. **Harvest the ugly shape.** Run the `ruff_*_spo` harvester over the + legacy source. Out come `(subject, predicate, object)` triples — the + **ore**. No interpretation yet, just facts. +2. **Re-encode as data-as-config.** A convention table (verbs, scopes, + aliases, codebook rows, surface kinds, region tokens) — a *runtime* + file, never Rust literals — tells the refiner how to read the ore. +3. **Let ruff + OGAR lift it into DTOs.** The mechanical bulk (85%) melts + into typed shapes: a class becomes a `ClassView`, an association becomes + an `EdgeBlock`, a method becomes an `ActionDef` recipe. +4. **Let the proposer tie loose ends.** What didn't melt cleanly is the + **slag**: unbound residues, fuzzy bodies, un-mapped screens. +5. **Turn every residual into the next config fact.** Each slag entry names + *exactly* the config row (an alias, a codebook mint, a recipe) that would + have melted it — so the next pass melts more. The furnace teaches itself. + +**The metal/slag split is a labor split too** (see §9): the melt is +Sonnet grindwork (edit-only, deterministic); the slag triage is Opus +judgment. Never invert it. + +### ore/slag decomposes God-objects into SoC + +A legacy God-object (a 4,000-line `Form`, a fat `ActiveRecord` model, a +Flask blueprint that does everything) does **not** transcode as one Rust +thing. The ore/slag pass *decomposes* it: each SPO fact is a single +responsibility, and the concepts they cluster into (§3) are the separated +concerns. You never decide the decomposition by hand — it falls out of +which facts share a concept witness. + +______________________________________________________________________ + +## 2. Two oracles — diverse redundancy is the safety + +A transcode is only trustworthy when *two independent witnesses* agree the +Rust reproduces the legacy app. Use two that fail differently: + +| Oracle | Witnesses | Question it answers | Source of truth | +|---|---|---|---| +| **Value parity** | the legacy **database** | "does the Rust write the same *bytes*?" | MySQL / PostgreSQL rows | +| **Structure parity** | the **Klickwege** (nav/route/view graph) | "does the Rust have the same *shape* — same screens, same order, same regions, same reachability?" | the harvested navigation graph | + +They are *diverse* — a value bug (wrong column) and a structure bug (wrong +menu order, missing screen) are caught by different oracles, so a single +blind spot can't hide a regression. The legacy DB is the permanent value +witness (it is never retired); the Klickwege digest is the permanent +structure witness. Any consumer that ships only value parity has a +half-tested UI; any that ships only structure parity has a pretty shell +over wrong data. + +**Klickwege = "click-paths".** It is the directed graph of screens, the +navigation edges between them, the views each screen selects, the concepts +each screen surfaces, and — on the render side — the region each control +docks in and its tab order. It is harvested, never authored. + +______________________________________________________________________ + +## 3. The three-axis mint gate — what earns a concept + +The furnace's central judgment: **when is a token a real domain concept +(worth a codebook classid) versus just a lookup/enum surface?** A token is +minted **only if witnessed on all three axes**: + +``` +CONCEPT ⟺ METHOD ∧ STORAGE ∧ STRUCTURE +``` + +- **METHOD** — a DAL / service / model family operates on it (there are + functions whose subject is this thing). +- **STORAGE** — a table / column / schema mirror persists it (the value + oracle has a home for it). +- **STRUCTURE** — a Klickwege screen gives it a navigational home (the + structure oracle can reach it). + +**Two axes out of three ⟹ it is NOT a concept** — it is a lookup table, an +enum, an RBAC filter, or framework plumbing. Mint it and you pollute the +codebook with non-concepts; every future session then has to reason around +a fake node. + +> Worked calls from the MedCare run: `external_practice` had all three +> (own DAL family + `sql_mirror` TTL + its own nav room) → **minted [G]**. +> `user_right` had method + storage but **no Klickwege home** → refused: it +> is the RBAC *global mask*, not a concept (and it later became exactly the +> `global_mask` term in the render equation, §6). That refusal is a *clean +> architectural closure*, not a gap. + +The gate is what keeps the codebook honest across consumers: the same three +axes apply whether the METHOD arm is a C# DAL, an Odoo `@api.model`, a Rails +`ActiveRecord` class, or a Flask view function. + +______________________________________________________________________ + +## 4. The no-hand-roll rule + the four sanctioned outputs + +**You never hand-author the transcode.** When you feel the urge to write a +Rust table/menu/mapping by hand, that urge is a signal: *extend ruff (or the +config) so the shape is derived instead.* The mantra: **"avoid handroll — +extend ruff so it's data-as-config through better ruff expansion."** + +The only things a furnace session is allowed to author are these four, and +each is a *generator or a check*, never the answer itself: + +1. **Harvesters** — a new arm on a `ruff_*_spo` walker that emits a new fact + family (worked example in §5). +2. **Convention configs** — runtime `.conf` rows (verb/scope/alias/codebook/ + surface/region) that tell the refiner how to read the ore. +3. **Proposer recipes** — `(verb, criteria)` codebook entries that correlate + fuzzy bodies to declarative recipes (see `fuzzy-recipe-codebook.md`). +4. **Residual DTOs + re-derivation tests** — the slag types, and the exam + that proves a former hand-table was only an unautomated config read. + +Three *sanctioned exceptions* — the small, deliberately-inert hand-authored +layers a consumer legitimately owns (from the MedCare render side): + +- **ONE generic frame template** (the six-region `base.html`, §6) — one + layout skeleton, not per-screen markup. +- **The concept→route join table** — the consumer's own claim about which + route serves each concept (the mirror of the harvest-side room-aliases). + It is data-as-config the *consumer* owns, not a hand-drawn menu. +- **Inert theme/skin** — CSS that only touches colour, zero structural + coupling. + +If a hand-authored thing is none of these four outputs and none of these +three exceptions, stop: there is a ruff arm or a config row missing. + +______________________________________________________________________ + +## 5. ruff expansion — the mechanical recipe (worked example) + +Adding a fact family is always the same three edits. Worked example: the +**region-grammar** family (WinForms Designer layout → six-region frame), +added for MedCare and directly reusable by every consumer's UI layer. + +**Edit 1 — the closed vocab** (`ruff_spo_triplet/src/triple.rs`): +add the `Predicate` variants, wire `as_str`/`from_str`/`ALL`/ +`default_provenance`, and bump the count-lock test. The vocab is *closed* +(a round-trip test enumerates every predicate) so a new fact can never +silently escape validation. Region-grammar added +`Predicate::{DockedAt, TabOrder, OpensPopup}` (wire `docked_at` / +`tab_order` / `opens_popup`), taking `ALL` from 73 → 76. + +**Edit 2 — the harvester arm** (`ruff__spo/.../Program.cs` or the +Rust walker): emit the new triples where the AST pattern matches. Region- +grammar added a switch arm: `Dock = DockStyle.X` → `docked_at`, `TabIndex` +→ `tab_order`, `ContextMenuStrip = m` → `opens_popup`. Same `Triple` shape +and provenance as the existing arms; a neutral fixture exercises it. + +**Edit 3 — the digest/exam consumer** (`nav_digest` / `rekey_exam` +examples): read the new facts into a diffable golden section. Region-grammar +added the `region=:` config directive and the `[regions]` / +`[menu-tree]` digest sections (controls grouped by region, ordered by +`tab_order`). Region names are free strings *from config*, never hardcoded. + +That is the entire pattern: **fact in the closed vocab → arm that emits it → +golden section that diffs it.** Every consumer's new fact family (Odoo XML +arch, Rails routes, Flask blueprints) is these same three edits. + +______________________________________________________________________ + +## 6. The render side — region grammar + the render equation + +The structure oracle has a *render* half: reproducing the legacy UI shape +without emulating its widget tree. The insight: **every legacy screen is a +declarative layout in disguise.** A WinForms `Dock=Fill`, an Odoo +`
`/``, a Rails ERB region, a Flask/Jinja block — all map onto +**one universal six-region frame**: + +``` +{ top_bar, left_nav, center, right_panel, bottom_bar, popup } +``` + +The convention is `predicate → (region, order, interaction)`: +- `docked_at`/arch-tag → **region**, +- `tab_order`/DOM order → **order within region**, +- `opens_popup`/context-menu → **popup interaction**. + +**Harvest + reimagine, never emulate.** You do not port the widget tree; +you harvest where things dock and re-render them into the clean frame. + +### The render equation (the WideFieldMask cast) + +For each region `R`, what actually renders is a masked, ordered projection: + +``` +live(R) = region_basis[R] ∩ global_mask ∩ local_mask +render(R) = live(R).ordered_by(harvested_order).as(interaction[predicate]) +``` + +- `region_basis[R]` — every entry the *manifest* declares for region `R`. + The manifest is the authoritative config (§6b) — there is **no + reachability drop** in this projection; a manually-added entry is + rendered, not swallowed. +- `global_mask` — a *session-wide* WideFieldMask = **`RBAC(role)` only**. + **RBAC / `user_right` IS the global mask** — this is where the concept the + mint gate *refused* (§3) does its real job: an entry survives only if the + role may see its concept. (Route *mounting* is NOT a runtime mask — it is a + test-time drift guard, §6b move 3. Whether an entry renders as a live link + or a planned placeholder is its own `enabled` flag, not a mask.) +- `local_mask` — a *per-screen* WideFieldMask the active view may narrow + further (default: show all). + +The frame is a **projection under two masks**, not a new struct wrapping the +axes. In the MedCare render, `nav::LayoutFrame` is exactly this projection, +and a **render→parse→re-derive parity test** renders the real page, +re-parses the region's order out of the HTML, and asserts it re-derives the +manifest — the render-side twin of the value oracle. + +### Concept is the join key between producer and consumer + +The harvested C#/Python/Ruby screen and the Rust route are bridged by the +**concept** (the thing the three-axis gate minted). The screen +`surfaces_concept X`; the consumer's join table maps `X → /route`; RBAC +gates `X`. So the nav order is *where each concept first appears in the +harvested navigation graph* — never hand-picked. The FAITHFUL default is +the legacy first-seen order (preserve muscle memory); an OPTIMISTIC +co-fire reorder ("fires-together-wires-together") is offered as an +**engineer's-gate** candidate, never auto-applied. + +______________________________________________________________________ + +## 6b. The render manifest is EDITABLE CONFIG — manual override + +The single rule that keeps a transcode alive instead of frozen: **the +render manifest (the emitted `nav-manifest.json` / config) is the +authoritative, hand-editable source of truth — not a locked build +artifact the deriver owns.** The deriver *seeds* it from the harvest; a +human then overrides it "from the end" (the desired end state). Get this +wrong and the substrate is glued to exactly what the harvest emitted and +impossible to keep working on. + +**The anti-pattern that glues it (do NOT ship this):** a hardcoded +reachable-routes set / allow-list in the *consumer code* that silently +**drops** any manifest entry it doesn't recognise. It means adding one +menu item requires editing code AND re-harvesting — the config is no +longer the config. If you find one, delete it (worked instance: +MedCare-rs `nav::reachable_routes`). + +**The four moves that keep it editable:** + +1. **Manifest is authoritative.** The runtime renders exactly what the + manifest says, filtered ONLY by *access* masks (RBAC / local / + patient-context), never by a reachability drop. A manual override is + rendered, not swallowed. +2. **`enabled` flag = the override switch** (data-as-config; default + true). A planned end-state entry (`enabled: false`) STILL renders — as + a disabled placeholder, not a link — so the manifest can carry the + *desired* end-state menu **before** its route exists. You build toward + it and flip the flag. This is "thinking from the end": put the whole + intended menu in config, mark what's live. +3. **Reachability is a TEST-TIME drift guard, not a runtime gate.** A + *live* entry pointing at an unmounted route fails CI (caught at test + time); planned entries are exempt. Safety without glue. +4. **Two override surfaces, both data-as-config, neither needs code or a + re-harvest:** edit the manifest JSON directly, or edit the deriver + (its `CONCEPT_ROUTE` for live rows + a `PLANNED_OVERRIDES` list for + end-state placeholders) and re-run it. Document the manifest header as + the hand-editable source so the next session doesn't treat it as + regenerated-only. + +**Why this is legitimate, not a hack:** the transcode target is an +**object-oriented representation** — ClassView / manifest / config is an +abstraction, so you modify it at the abstraction layer. Data-as-config +means the config author is responsible for the config being correct +(a live entry with a bad route is *their* CI failure, per move 3); the +system's job is to render the config faithfully, not to second-guess it +by dropping rows. + +**The consumer render seam that makes it work** (one `NavEntry` shape, +one projection): each entry carries `{concept, scope (global|patient), +route, route_template, order, enabled}`; the frame is a *projection* of +the manifest under the access masks, computing a per-render `href` +(global → bare route; patient → template with the id filled) so the +render never emits an unmounted URL, and reading `enabled` to choose +link-vs-placeholder. Same seam for every consumer; only the manifest +(config) differs. + +______________________________________________________________________ + +## 7. The furnace exam — the re-derivation test + +The proof that a transcode is honest: **re-derive the domain concepts from +the harvest, through the pipeline, and check them against the codebook.** +`rekey_exam` does exactly this — `ndjson → reassemble → concept_split +(convention config) → codebook check` — and: + +- **green** means a table you might have hand-authored was only an + unautomated config read (the furnace could regenerate it); +- every **unbound residue** is printed as a ranked candidate — literally the + next config fact to add. + +Corpus-agnostic by construction: the corpus, the convention table, the +codebook rows, and the expected-concept list all arrive as runtime config — +no corpus tokens in the test, no corpus data committed. This is the check +that makes "data-as-config" falsifiable rather than aspirational. + +______________________________________________________________________ + +## 8. Portability map — same furnace, four legacy stacks + +The loop is identical; only the *ore source*, the two *oracles*, and which +harvester arm you run differ.

The rolling bucket — win the guessing game + +A coarse triage is a *first pass*; it will misfile recoverable recipes into a +FAIL bucket because a coarse predicate can't split them. **Roll the FAILs +through the finer codebook and watch the residue shrink until it's only the +essential kinds.** That convergence IS "won". + +Worked example (F17, Redmine, arm 62): + +``` +Round 0 (coarse triage): PASS 58 / FAIL 4 (self-feedback 3 + write+raise 1) +Round 1 (recipe codebook): the coarse self-feedback bucket was FUZZY — R∩W + cannot tell an idempotent SelfMap (order-free) from real accumulation. + Rolled: FAIL 4 → SelfMap 2 (recovered) + Compute 1 (recovered) + Compensate 1 (essential) +Result: Cascade 46 · Compute 13 · SelfMap 2 · Compensate 1 + recoverable 61/62 = 98.4% (upper) .. 93.8% (Authoritative-only, Cascade dropped) + IRREDUCIBLE CORE = 1 Compensate ← the game is won: no recoverable + recipe left stranded in a FAIL bucket +``` + +**Win condition (make it a test assertion):** the irreducible core contains +ONLY essential kinds. If a *recoverable* recipe is still hiding in FAIL, you +haven't rolled far enough — refine a centroid or capture a new fact. If the +essential core *grows*, that's a finding (a new order-dependent shape), not +noise — characterize it. + +## 5. The jitter codebook — collect the residuals, each names the next fact + +Correlation is fuzzy by design; the residuals are not failures, they're the +**map of what one more fact would buy.** Record them as a codebook: + +- **J1 — SelfMap degeneracy. ✅ RESOLVED (`writes_if_blank`).** `normalizes` vs + schema-default were identical under `(W, R)`. The **guard-predicate fact** now + splits them (`x.blank?`/`.nil?`/`.empty?` guard, or `unless x.present?` ⇒ + default; unconditional transform ⇒ normalize). Both order-free, so the PASS + rate was never affected — only the *emit target* differed, and it is now + determined. Implementation: `ruff_ruby_spo::detect_guarded_default`, + `Function::guarded_writes`, predicate `writes_if_blank` (Authoritative). This + is the worked example of "a jitter residual names the next fact, then you + capture it" — the loop closes. (Deferred sub-case: `self.x ||= v` op-assign, + not yet captured as a write at all — module-doc D-AR-3.6.) **Port this fact to + the other frontends** when they get the arm: the guard shape is language- + universal (`??=` in C#, `if (x == null)` in C#/C++, `x = x or default` in + Python). +- **J2 — Cascade rests on Inferred `calls`.** The residual is the + receiver→`dependent:`-kind codebook (`page.destroy`, `line_ids.update_all`). + This is why the answer is a **band** (93.8–98.4%), not a point. → next fact: + resolve the call receiver to a declared association. +- **J3 — composite body.** One hook can be normalize(a,b) + compute(c); the + recipe is the **set**, not one entry. Order-free if every sub-recipe is. → + next fact: nothing — just emit a recipe *list* per method. + +The jitter codebook is the actionable output: it turns "98.4% recoverable" +into "here are the exact three facts that take it to 100% *targeted*." + +## 6. How to cook it (the recipe for the recipe codebook — reproducible) + +1. **Pick the reference frontend** with the fullest arm (`ruff_ruby_spo` + today). Cook here first; port the arm to other frontends after. +1. **Point at a real corpus.** Env-gate + self-skip (ruff #44 house style): + `RAILS_CORPUS_SRC=/path RAILS_CORPUS_NS=redmine cargo test … -- --nocapture`. + Never a synthetic fixture for a measurement leg — real bodies or nothing. +1. **PRE-REGISTER thresholds before the first run** (write them in the module + doc): the pass bar, the KILL floor, the expected tail shapes. The noun-side + 26/26 is *asserted*, so the behaviour side may not borrow it — register its + own gate. (This is the C5/A-B discipline.) +1. **Coarse triage first, then roll** (§4). Two probes, not one: the coarse + pass is the honest baseline; the recipe codebook is the refinement. Keep + both so the delta is visible. +1. **Read the tail bodies in source.** Do NOT infer the tail's shape — open the + files, confirm each FAIL is what the fingerprint claims (§5 J-notes came + from reading four real bodies). +1. **Pin the histogram as a drift fuse.** `assert_eq!` the per-bucket counts + guarded on the corpus signature, so a silent harvest/walker change trips + loudly. Other corpora print fuse-free. +1. **Record the jitter codebook** as the finding, and file each residual as a + named next-fact for the frontend. + +## 7. Anti-patterns (the ways this goes wrong) + +- **Transcribing instead of correlating.** If your output has one Rust fn per + C# method, you reproduced the fuzz. Correlate to a recipe; emit the recipe. +- **Synthetic corpus for a measurement.** A hand-written fixture proves the + code runs, never that the *claim* holds. Measurement ⇒ real corpus. +- **Coarse-only, no roll.** Stopping at the first triage over-counts the tail + (F17 coarse said 6.5% FAIL; the roll showed 1.6% essential). Always roll. +- **Point estimate on Inferred facts.** When a bucket rests on Inferred + (`calls`), report a *band* (drop it from num+denom for the lower bound), not + a single number. +- **Silent scope boundary.** Hooks targeting concern/`lib` methods outside the + harvest scope are "no-facts" — EXCLUDE them, never count them as PASS, and + print the count so the boundary is visible. +- **Fixing a body "bug" mid-transcode.** Behaviour-preserving: a weird body is + a finding for an RFC, not a silent fix. + +## 8b. The SoC proposer — when a bucket OVERFLOWS, propose a split (don't widen) + +The recipe codebook classifies *methods*. The same fuzzy→exact instinct applies +one level up, to *classes and routes*: when a bucket overflows a cap, that is a +**separation-of-concerns signal**, not a reason to widen the container. Two +overflow detectors, both feeding the OGAR reserved SoC families (Scope `0x05`, +Concern `0x06`, mint-**on-emit** per `E-RECIPE-FAMILIES-MINT-ON-EMIT` — do NOT +pre-mint): + +- **God-object bucket overflow → Concern split.** A class whose field count + exceeds `FIELD_MASK_CAP = MAX_SIBLINGS_PER_TIER` (256), or whose method-recipe + histogram spans many unrelated recipe clusters, is a **god object**. The + proposer does NOT widen the FieldMask past 256 (that path is explicitly a + non-use-case, lance-graph #651 / OGAR doctrine) — it emits a **Concern** + (`0x06`): partition the fields+methods into cohesive sub-ClassViews (Rails + `concerns`/mixins; the `ruff_spo_address::soc` `Conflation` verdict). The + bucket cap is the trigger; the split is the recipe. Cook it the same way: + fingerprint each member by which sub-cluster it touches, roll until each + sub-ClassView is cohesive, name the residual (members that genuinely span + concerns — the essential coupling). +- **Duplicate-routes bucket overflow → Scope split.** When N controller routes + differ only by a filter predicate over the SAME resource (a `ruff` DTO-AST + route-dedup finds them collapsing to one `ClassView` + a fieldmask), that is a + **Scope** (`0x05`): a named filtered view (Rails `scope`/`default_scope`), not + N separate actions. The dedup is the detector; the named scope is the recipe. + One `ClassView` fieldmask standing in for N routes IS the emit seam that mints + Scope. + +Rule of thumb: **a recipe correlates a body to an existing lift; an SoC proposal +fires when NO single bucket can hold the thing without overflow — the answer is +a split, never a wider bucket.** The rolling-bucket loop is identical; the +"win" is every member landing in a cohesive sub-bucket with a named residual. + +## 8c. Detected `config.json` becomes DATA (the training-wheel → data rule) + +When the harvest DETECTS a configuration artifact — a `config.json`, a +migration-DSL schema, an ORM→AR back-projection map, a route table — that +artifact **becomes a data input to the codebook, not code to transcribe.** The +config is a *codebook already written by a human*; ingest it as centroids / +priors, don't re-derive it and don't reimplement it. + +Worked precedents in-tree: + +- op-nexgen `.claude/harvest/orm-ar-backprojection.toml` — the ORM→AR resolver + config: detected column facts (migration DSL) become the *data* that guesses + AR declarations, closing the 90→100% model-shape gap. It is data, the ONE + training wheel the consumer owns; everything else retires into the pipeline. +- OGAR `ogar_codebook` / `ruff_spo_address` `class_ids` — the concept codebook + is data the frontend *reads* to mint classids, never a table each consumer + re-hardcodes (the consumer anti-pattern: copying the codebook — see + `ogar-consumer-preflight`). + +The discipline: **detect → ingest as data → correlate against it.** A detected +config that gets transcribed into imperative branches is the same mistake as +transcribing a method body — you turned a declarative codebook back into fuzz. +When you find a config, register it as a fact source (like the schema stratum), +and let the recipe/SoC correlation run against it. `config.json` → codebook row, +not `config.json` → `if/else` ladder. + +## 8. Why this is the DO-arm's foundation + +OGAR's DO arm (`ActionDef` + `KausalSpec`) is *the recipe*, not the body. This +codebook is how a producer frontend decides, per method, whether a body lowers +to a declarative recipe (85%: `normalizes`/default/compute/cascade/guard → +`ActionDef`) or must stay a hand-ported imperative core (15%: +compensate/write-raise → raw method). Cook the codebook per language, and each +consumer collapses to "a compiler-store caller + a small essential residue." +That is the 85/15 split, measured rather than asserted. diff --git a/.claude/plans/behavioral-ore-v1.md b/.claude/plans/behavioral-ore-v1.md new file mode 100644 index 00000000000000..ee93fa104850cd --- /dev/null +++ b/.claude/plans/behavioral-ore-v1.md @@ -0,0 +1,178 @@ +# Ordered behavioral ore for C++ — plan v1 + +**Status:** IN PROGRESS.

Neutrality rules — the ore must not pre-solve the experiment + +1. **No inferred motifs in the alphabet.** The 20 kinds are primitive + (`ScopeEnter`/`Read`/`Call`/`Condition`/…). There is no `RAII`, + `IteratorLoop`, `VirtualDispatch` or `Move` kind. A `lock_guard` local is + `Decl` + a type symbol; `std::move(x)` is `Call` + a callee symbol. Those + concepts are candidate LEARNED tokens; emitting them would be the + tokenizer's answer written into its input. +2. **No consumer vocabulary.** Nothing about classids, facets, rails, masks or + any 96-bit layout appears in the ore or in this crate. The ore does not + know those exist. +3. **Identities are verbatim, never hashed.** Different consumers hash + differently; a hash in the ore forces one of them. +4. **Lexical order and control flow stay distinguishable.** Every event carries + its source byte `anchor`. `control` carries only structurally-certain + relations. **libclang's C API exposes no CFG** — successor/predecessor + edges are not available and are never fabricated. A later probe may ask + whether CFG adjacency beats lexical adjacency; it cannot ask it from these + files, and must say so rather than assume the two are the same. + +## 4. The control + +`for (…) { if (…) foo(); else bar(); }` — the expected event sequence was +hand-written BEFORE the extractor existed. Where libclang disagrees (AST child +order for `ForStmt` is init/cond/inc/body, which is not source order), the +disagreement is reported and the `anchor` column keeps both orders separable. +It is not resolved by editing the expectation to match the code. + +## 5.

A new + cross-frontend test, `expand::tests::cpp_method_body_arm_expands_to_the_function_quartet`, + asserts the exact predicate/object shape on a fixture and a silence half (no + arm-less overload gains a body fact); `expand::tests::cpp_truth_tiers_match_calibration` + is extended to assert the C++ tiers match a hand-built `Function` carrying the + same five facts, fact-for-fact. (Correction, same day: an earlier draft of + this entry named `provenance_tiers_match_ruby_reference`; no test of that + name exists in the crate.) +- `recipe::classify` — previously typed `fn classify(f: &Function)`, even + though its own doc comment already claimed to classify "Ruby hooks, Odoo + `_compute_*` methods, C# handlers, and C++ methods alike" — is now + `fn classify(f: &F)`, generic over a new `BodyFacts` + trait (`writes`/`reads`/`raises`/`calls`/`guarded_writes` accessors) + implemented for both `Function` and `CppMethod`. A new test, + `a_cpp_method_and_a_function_with_the_same_facts_classify_alike`, walks all + nine centroids (`Compensate`/`Cascade`/`Guard`/`WriteRaise`/`Default`/ + `Compute`/`Normalize`/`Observe`/`Empty`) and asserts a `CppMethod` and a + `Function` carrying the identical fact-set land on the identical centroid + every time — so the doc's cross-frontend claim is measured, not aspirational. +- `CppMethod` joined the DTO-surface lock as `CPP_METHOD_DTO`, and + `cpp_method_body_arm_keys_are_the_function_body_keys` asserts the five + body-arm keys sit in BOTH `FUNCTION_DTO` and `CPP_METHOD_DTO` — a rename on + one side now fails a test on the other before it ships. +- The walker (`clang_walker.rs`) was corrected against three defects the + earlier draft's own status comment admitted it could not have caught without + a real TU: (1) libclang exposes no binary-operator KIND on stable, so the + draft recorded the LHS of ANY binary operator (`if (status_ == v)`) as a + write — the operator is now read off the token stream + (`binary_operator_spelling`); (2) the assignment target also landed in + `reads`, so a pure setter classified `Normalize` instead of `Compute`; (3) + `guarded_writes` was never populated at all, so J1 could not fire on C++. + Two further shapes were found only by dumping real cursors, not by reading + the AST docs: a class-typed member assigns through `operator=` (arrives as a + `CallExpr`, not a `BinaryOperator`), and a call's own callee reference is a + `MemberRefExpr` that would otherwise misread as a read of a field named + after the method. +- `walk_tu` now parses bodies by default (`skip_function_bodies(false)`); + `walk_tu_configured(path, args, None)` opts back out for a faster + signature-only walk (arm left empty, signature plane byte-identical either + way — asserted by `a_signature_only_walk_leaves_the_arm_empty`). + `BodyArmConfig::{with_mutators, with_mutator_prefixes}` makes the + lifecycle-mutator vocabulary corpus-configurable, mirroring the C# + `--mutator-prefixes` generalization the codebook doc §2 already documents + (tested by `the_mutator_vocabulary_is_configurable`). +- The arm is harvested from `Entity::get_definition()`, not the declaration + cursor — required because a method declared in a header and defined + out-of-line in a `.cpp` has its body on a DIFFERENT cursor + (`an_out_of_line_definition_is_harvested_through_the_declaration` pins this). + `walk_files` (`ruff_cpp_spo::lib`) now merges body arms across translation + units via a new `merge_body_arms`: first-wins stays right for the signature + plane (every sighting of a declaration agrees), but the header's sighting of + an out-of-line method is arm-less, so an already-inserted empty arm is + filled from a later TU that has one — keyed on `(name, param_types, + is_const)` so a merge can never move one overload's body onto another, and + never overwriting an already-non-empty arm (so the result does not depend on + TU visit order). + +**MEASURED, not merely reviewed:** + +- Every cursor shape the walker matches (`x_ = v`, `p.x_ = v`, + `this->x_ = v`, `x_ += v`, `++x_`, `arr_[i] = v`, `repo_.Save()`, + `name_ = s` via `operator=`, `throw E()`) is documented in `clang_walker.rs` + as measured against **real libclang 18** on a fixture built for each + construct — the module comment says so explicitly ("Every cursor shape + matched below was measured against libclang 18 on a fixture carrying each + construct, not inferred from the AST documentation"). This checkout has + `libclang-18.so` present (`/usr/lib/llvm-18/lib`), consistent with the + `#[cfg(feature = "libclang")]`-gated tests actually running here rather than + being reviewed-only. +- `#[test]` counts, verified with `git show : | grep -c '#\[test\]'` + at the commit and its parent (a static source count, NOT a `cargo + test`/`nextest` run — I did not run cargo, per this session's constraints): + `ruff_cpp_spo/src/*` goes **23 → 41** (`clang_walker.rs` alone 6 → 23; + `lib.rs` 17 → 18 for the new cross-TU merge test); `ruff_spo_triplet/src/*` + goes **170 → 176** (`ir.rs` +2, `expand.rs` +1, `reassemble.rs` +2, + `recipe.rs` +1). Note the plan's own last "Test count" line above (58 + 15, + from 2026-06-17) is now far stale relative to the parent commit's actual + 170 / 23 — other, unrelated commits landed a great many tests on both + crates between 2026-06-17 and today; that drift predates and is unrelated + to this session's change. +- The commit message additionally claims "every guard is disable-verified + red-then-green (16 checks)." I did not independently re-run the + disable/re-enable exercise (that needs `cargo test`, which I did not run), + so I cannot confirm the count of 16 myself — I can only report that the + commit states it, and that one specific instance is corroborated by a code + comment (below). The 16 is a claim about *behavioral guards*, not the same + number as the 24 new `#[test]` functions above (a guard and a test are not + 1:1 — several of the new tests share one guard, and some pre-existing tests + were extended with new assertions against an already-counted `#[test]`). +- Two of those 16 disable runs came back green on the first pass and were + investigated rather than accepted, per the commit message. **One is fully + explained**, in both the commit message and a code comment on + `a_body_defined_out_of_line_survives_the_cross_tu_dedup` + (`crates/ruff_cpp_spo/src/lib.rs`): the cross-TU fixture's header, parsed + without `-x c++`, was silently interpreted as **C** by libclang's + extension-based language guess, so the header's `struct Svc` failed to + parse as a C++ class at all — the header contributed nothing, the `.cpp`'s + sighting was the ONLY sighting, and first-wins (i.e. no merge at all) + looked like a working merge. Fixed by adding `-x c++` to the test's `args` + and an up-front assertion (a direct `walk_tu_with_diagnostics` call on the + header alone) that the header's own sighting really is arm-less, so the + test cannot pass unless there are genuinely two different sightings to + merge. The other was **a mis-aimed disable, not a + weak test**, and is identified here because the commit message left it + abstract: the target was `a_signature_only_walk_leaves_the_arm_empty`. That + opt-out is enforced TWICE — the TU is parsed with `skip_function_bodies`, and + `build_method` does not harvest — so disabling either mechanism alone leaves + the behaviour correct and the test green. Forcing the parse flag on turns it + red, and so does forcing both. That is redundancy rather than vacuity, and it + is now recorded in a doc comment on the test itself, so a future reader who + wants to drop one of the two mechanisms as dead weight learns up front that + no single test will notice. + +**NOT yet measured — stated explicitly, not by omission:** + +- **Correction, same day** — an earlier draft of this entry said the feature + had "zero corpus-scale numbers". A one-off census HAS since been run, and + its numbers are below. **Second correction, same day:** + `crates/ruff_cpp_spo/examples/harvest_ladybug.rs` now reports the body arm + too — the five fact totals, a full `RecipeCentroid` census, and a + top-classes-by-body-fact list — so the census is re-runnable rather than + one-off. What is still missing is a *gate*: the example prints, it does not + assert, so a regression would show up in the output and fail nothing. On + `src/include/catalog` (headers only) it reports 2424 methods, 381 with at + least one body fact, census `Observe=283 Compute=62 Normalize=19 + Cascade=10 Guard=7` — and that 381 agrees exactly with an independent count + of body-predicate subjects in the emitted ndjson, which is the cross-check + that makes the census trustworthy rather than merely present. + + `extract_tree` over `ladybug/src/catalog` (358 classes), every `CppMethod` + through `recipe::classify`: + + | | `-std=c++17` | `-std=c++20` | + | --- | ---: | ---: | + | methods | 2782 | 2794 | + | non-`Empty` centroid | 362 (13.0%) | 577 (20.7%) | + | writes / reads / raises / calls | 110 / 373 / 13 / 8 | 126 / 692 / 23 / 28 | + | census | `Observe=253 Compute=67 Normalize=21 Guard=13 Cascade=8` | `Observe=431 Compute=74 Cascade=25 Normalize=24 Guard=23` | + + **The two columns are the same corpus, one of them parsed wrongly, and the + gap is the finding.** `common/assert.h` needs `std::format`, so under + `-std=c++17` libclang emits an error diagnostic and recovers by silently + dropping declarations — costing a third of the body facts. That is exactly + the partial-AST failure mode `walk_tu_with_diagnostics`'s own doc comment + warns about ("0 failed from `walk_tu` alone does NOT mean the sweep is + complete"), reproducing on a real tree rather than in a fixture. Any future + corpus run must pass the standard the corpus actually needs and must read + the diagnostics, or it will quietly under-count. + + `guarded_writes` is **0** across all 2794 methods, and that is the corpus + rather than the detector: a search of the whole `ladybug/src` tree finds + three absence tests on a member, and all three are early returns or an + assertion — none is a guarded write. So there is still no C++ analog of the + Redmine "SelfMap population 1 Default / 3 Normalize" J1 split, but the + reason is that this corpus does not use the lazy-init shape, not that the + detector failed to see it.

Do not mistake the cleanliness of r2il's Rust types for +refinement — that mistake is exactly the "privileged direct path" the pivot +forbids. + +## CARRIED FORWARD (2026-08-18) — the ruff/r2sleigh half of the console ruling + +The operator's Ghidra-console ruling belongs to a different session; the +console, the Java extension, and the forensic product families are **out of +scope here**.

Recorded so they are not re-derived: + +**C1 — the library seam must survive an external caller.** Falsifiable test: +*could a thin external caller analyze one function and obtain structured +ore/furnace/slag results without parsing CLI strings or NDJSON?* **Measured +YES** — every entry point is a typed Rust fn over library types +(`FunctionBehavior::from_blocks_raw`, `furnace::smelt`, `ResidualLedger::*`, +`HarvestReport::*`); the CLI/TSV/TOML surfaces exist ONLY inside the two +`lift`-gated examples, whose artifacts are declared *evidence, never a +re-ingest path*. **Do not seal the API around CLI-only assumptions** — no RPC +protocol now, just keep the typed seam public. + +**C2 — provenance must reach the native instruction, not just the block.** +`FactProvenance.op_site: (block_addr, op_idx)` → +`R2ILBlock::op_metadata[op_idx].instruction_addr: Option` +(r2il `metadata.rs:103`: *"Source instruction address for this operation when +lifted as part of a block"*). **SSA does not carry it**, so this sidecar +rejoin IS the anchor — the same `(block_addr, op_idx)` key +`SsaGraph::op_inst_by_site` uses. Landed as `ore::instruction_addr(prov, blocks)` so a caller finds a named API instead of rediscovering a convention. +Chain: `fact → concern route → SSA/R2IL fact → instruction address → artifact`. + +**C3 — the conservation ledger is load-bearing, not diagnostic decoration.** +Three readings of one number: *what did the target fail to represent* +(transcode) · *what have we not yet explained* (reconstruction) · *what still +needs attention* (any investigative use). `dropped == 0` is what makes it +evidence rather than a progress bar. Already the PR-1 invariant; this +elevates it from QA metric to product property. + +**C4 — transcode is TARGET-ARCHITECTURE PROJECTION, not syntax conversion.** +`behavioral truth → target recipe → generated implementation`. A recovered +pointer graph does NOT oblige a pointer graph in the target; the furnace emits +concern-separated facts and a target profile decides the layout.

Corollary for the eventual roundtrip +oracle: **success is semantic/behavioral parity, never textual or binary +equality** — which is exactly why §14's reconstruction oracle is specified as +`R2IL → routes → semantic-equivalent R2IL`, with SPO explicitly NOT the oracle. + +## SUBSTRATE RULING (operator, 2026-08-18): THREE backends, none privileged + +The refined-truth sink must support **all three**, chosen at the seam, never +baked into the furnace: + +1. **Offline V3 substrate** — file/artifact-shaped, self-contained, no service. + What the PR-1 harvest artifacts already are. +1. **lance-graph zero-copy SoA** — live storage AND audit layer, so a future + external consumer can drill on the fly instead of re-harvesting. Zero-copy is + the point: rows are read in place from the SoA, never re-materialized. +1. **S3 object storage via `AWS_*` env vars (Railway Tigris)** — the same V3 + artifacts addressed remotely. Tigris is S3-compatible, so this is credential + plumbing (`AWS_ACCESS_KEY_ID` / `AWS_SECRET_ACCESS_KEY` / + `AWS_ENDPOINT_URL_S3` / `AWS_REGION`), **not** a fourth format. Never hardcode + an endpoint or embed a key; read the environment, and if unset fall back to + local offline mode rather than failing. + +**PR-1 consequence — a door to keep open, not work to do now.** The furnace +already returns `Vec` + `ResidualLedger` + `HarvestReport` in memory +and persists nothing; the examples write artifacts, the library does not. That +is exactly the shape all three backends need, so **PR 1 requires no change** — +the constraint is: do NOT introduce a persistence assumption into +`furnace`/`ore`/`slag`. PR 2 adds a sink trait behind which offline / lance-graph +/ S3 are implementations.

The split is by SHAPE of the work, not by how hard it looks: + +**Sonnet agents** — find every call site of X; quote a definition; trace a +constant's readers; check whether a symbol exists anywhere; run a scoped command +and report the tail; census a corpus. + +**Main thread** — whether a review finding is actually correct; what a +measurement means; designing a falsifier; deciding a divergence is defensible +rather than a defect. + +The rule bites on SWEEPS — "every site that reads this", "does this exist", +"which of these five shapes are real". For a single lookup where the file and +symbol are already known, going direct is cheaper than briefing an agent. + +Haiku is now allowed for grindwork (operator, 2026-10-14: "Use Haiku 5.5 for +grindwork"). This replaces the earlier "never Haiku" line. Use it for the +mechanical end of the list above: running a pre-written, scoped command and +reporting the tail; listing candidate call sites; counting; quoting text with +line numbers. Haiku never edits source, never concludes, and never judges +whether a result means what it appears to. The main thread checks every Haiku +result it relies on: it reads the cited lines itself, re-runs at least one +reported count, and never takes "no hits" as proof of absence. Sweeps that +need several sources held together still go to Sonnet. This follows the Haiku +tier already used in the sibling `lance-graph` and `tesseract-rs` workspaces. + +## Session traps (each one cost real time in this repo) + +**Commit BEFORE you disable, not after.** The disable-verification cycle is +`break the guard → watch the test fail → restore`, and the restore is +`git checkout <file>`. That reverts to the last COMMIT, not to the state you +started from — so if the work under test is uncommitted, the restore deletes +it. Measured: a fix plus its new test were both eaten this way, and the loss +was only noticed because a later grep showed the old code back in place. +Order is: commit, then disable, then checkout. + +**A disable that does not apply is indistinguishable from a guard that is not +load-bearing.** Both look like "the test still passes".

Always assert the replacement actually happened: + +```python +assert s.count(old) == 1, "anchor moved" +``` + +Related: turning a knob is only a disable if the knob BINDS. Zeroing a +constant proves nothing when the guarded quantity can reach the same outcome +by another route, or when a different `min()` term is the binding one. + +**`git status` reports CLEAN, not CURRENT.** A stale branch does not merely +give stale answers — it manufactures findings that do not exist on `main`. +Before the first measurement in a fresh container, and after any rebase: + +```sh +git fetch origin main && git log --oneline -1 origin/main +git merge-base --is-ancestor origin/main HEAD || echo "STALE — re-measure after rebase" +``` + +Re-run the measurement after a rebase; a conclusion drawn before it does not +survive it, and has previously outlived the rebase in a PR body. + +**`prek` cannot run in this sandbox, so Markdown edits ship unchecked.** The +local `uv run --locked prek` fails on a `uv` version that cannot parse this +repo's `exclude-newer`, so the hook set never runs here — and CI's `prek` job +then fails on formatting the edit introduced.

Avoid expanding the task to unrelated issues, but do not confuse keeping the task focused with minimizing the size of the implementation. Prefer addressing the underlying architectural problem over adding a localized workaround, even when doing so requires a substantial refactor or rearchitecture. Ask the user for guidance if in doubt about whether to attempt a larger refactor or not. - Try hard to avoid patterns that require `panic!`, `unreachable!`, `.unwrap()` or `.expect()`. Instead, try to encode those constraints in the type system. Don't be afraid to write code that's more verbose or requires largeish refactors if it enables you to avoid these unsafe calls. - Prefer let chains (`if let` combined with `&&`) and let guards (`PAT if let ... =>`) over nested `if let` statements to reduce indentation and improve readability. At the end of a task, always check your work to see if you missed opportunities to use `let` chains or `let` guards. -- If you _have_ to suppress a Clippy lint, prefer to use `#[expect()]` over `[allow()]`, where possible.

But if a lint is complaining about unused/dead code, it's usually best to just delete the unused code. - Don't use comments to narrate code, but do use them to explain invariants and why something unusual was done a particular way. Make sure that a comment will make sense to somebody who's reading the code for the first time. Prefer plain language, avoid jargon, and don't be afraid to be more verbose if it's necessary to explain something well. Giving examples of the kind of Python code we're trying to model at this particular point in Ruff or ty can often be very helpful for future readers of the code. - Run `cargo dev generate-all` after changing configuration options, CLI arguments, lint rules, or environment variable definitions, as these changes require regeneration of schemas, docs, and CLI references. - Don't prefix tests with `test_`. diff --git a/Cargo.lock b/Cargo.lock index a07ef6fbbdf04d..792ed1a6439a92 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -17,6 +17,12 @@ dependencies = [ "memchr", ] +[[package]] +name = "alloc-from-pool" +version = "1.0.5" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "bee030c58cf5648ea793d06e5aa6039f913bfbf9f68a0635c76ba429d393fa6c" + [[package]] name = "alloca" version = "0.4.0" @@ -493,6 +499,27 @@ dependencies = [ "half", ] +[[package]] +name = "clang" +version = "2.1.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "b2ed30b30e1e17966b55ddd0b9dd2758fd824f0a6da6875c8abb17e6aba47c28" +dependencies = [ + "clang-sys", + "libc", +] + +[[package]] +name = "clang-sys" +version = "1.9.1" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "157a8ba7b480713b56f4c09fd13fc3e0a22a5dfab8097ba61cbc5feef950788a" +dependencies = [ + "glob", + "libc", + "libloading", +] + [[package]] name = "clap" version = "4.6.6" @@ -1923,6 +1950,22 @@ version = "0.1.0" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "09edd9e8b54e49e587e4f6295a7d29c3ea94d469cb40ab8ca70b288248a81db2" +[[package]] +name = "lib-ruby-parser" +version = "4.0.6+ruby-3.1.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "8a64ffd6ab03aa1e6a986b42260202e25fb8d197dd7be0de11088cca389f67ce" +dependencies = [ + "alloc-from-pool", + "lib-ruby-parser-ast", +] + +[[package]] +name = "lib-ruby-parser-ast" +version = "0.55.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "461948472e72b507a0f97e144c453e29b8772e986f18b410e0f2318edd45258c" + [[package]] name = "libc" version = "0.2.189" @@ -1954,6 +1997,16 @@ dependencies = [ "syn 2.0.119", ] +[[package]] +name = "libloading" +version = "0.8.9" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "d7c4b02199fee7c5d21a5ae7d8cfa79a6ef5bb2fc834d6e9058e89c825efdc55" +dependencies = [ + "cfg-if", + "windows-link 0.2.1", +] + [[package]] name = "libm" version = "0.2.16" @@ -3187,6 +3240,29 @@ dependencies = [ "argfile", ] +[[package]] +name = "ruff_cpp_codegen" +version = "0.1.0" +dependencies = [ + "ruff_spo_triplet", +] + +[[package]] +name = "ruff_cpp_spo" +version = "0.1.0" +dependencies = [ + "clang", + "ruff_cpp_codegen", + "ruff_spo_triplet", +] + +[[package]] +name = "ruff_csharp_spo" +version = "0.1.0" +dependencies = [ + "ruff_spo_triplet", +] + [[package]] name = "ruff_db" version = "0.0.17" @@ -3521,6 +3597,24 @@ dependencies = [ "test-case", ] +[[package]] +name = "ruff_python_dto_check" +version = "0.1.0" +dependencies = [ + "anyhow", + "clap", + "globset", + "regex", + "ruff_python_ast", + "ruff_python_parser", + "ruff_source_file", + "ruff_text_size", + "serde", + "serde_json", + "sha2", + "walkdir", +] + [[package]] name = "ruff_python_edits" version = "0.0.17" @@ -3653,6 +3747,15 @@ dependencies = [ "test-case", ] +[[package]] +name = "ruff_python_spo" +version = "0.1.0" +dependencies = [ + "ruff_python_ast", + "ruff_python_parser", + "ruff_spo_triplet", +] + [[package]] name = "ruff_python_stdlib" version = "0.0.17" @@ -3697,6 +3800,14 @@ dependencies = [ "toml 1.1.6+spec-1.1.0", ] +[[package]] +name = "ruff_ruby_spo" +version = "0.1.0" +dependencies = [ + "lib-ruby-parser", + "ruff_spo_triplet", +] + [[package]] name = "ruff_server" version = "0.0.17" @@ -3751,6 +3862,30 @@ dependencies = [ "serde", ] +[[package]] +name = "ruff_spo_address" +version = "0.1.0" +dependencies = [ + "ruff_spo_triplet", +] + +[[package]] +name = "ruff_spo_triplet" +version = "0.1.0" +dependencies = [ + "serde", + "serde_json", +] + +[[package]] +name = "ruff_sqlalchemy_spo" +version = "0.1.0" +dependencies = [ + "ruff_python_ast", + "ruff_python_parser", + "ruff_spo_triplet", +] + [[package]] name = "ruff_text_size" version = "0.0.17" diff --git a/Cargo.toml b/Cargo.toml index 03b948d730b889..d3674bd1de9269 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -1,11 +1,17 @@ [workspace] members = ["crates/*"] +# ruff_r2il is a workspace-EXCLUDED standalone crate (its own workspace root): +# it path-deps the r2sleigh sibling checkout (r2il/r2ssa), and exclusion keeps +# the main workspace and its Cargo.lock sibling-free.

And `walk_body` gives `ForStmt` / `WhileStmt` / `DoStmt` / +//! `ForRangeStmt` / `SwitchStmt` / `TryStmt` / `LambdaExpr` no match arm at +//! all — their contents are visited, their boundaries are recorded nowhere. +//! +//! So the shipped representation cannot express *a write inside a loop*, *two +//! writes in a row*, or *a call in the else-branch*. Those are exactly the +//! shapes a behavioral vocabulary would be made of. A sequence learner run +//! against that output is learning words from a bag of letters. +//! +//! This module is a SECOND walk over the same cursor that preserves three +//! things separately: +//! +//! | preserved | where | deduped | +//! |---|---|---| +//! | event identity | [`Symbols`] | yes — the only place | +//! | event order | [`MethodOre::events`] | **never** | +//! | structural context | [`MethodOre::scopes`] | n/a | +//! +//! The same fact occurring twice is two events pointing at one symbol. +//! +//! # Additive by construction +//! +//! Nothing here changes `method_body_arm`, `BodyArm`, `CppMethod`, `expand` +//! or the emitted ndjson. `events_collapse_to_the_shipped_five_sets` asserts +//! that folding these events back into sets reproduces the shipped arm +//! exactly — the change is about what is PRESERVED, not about what a fact is. +//! +//! # Neutrality — the ore must not pre-solve its consumer's experiment +//! +//! The alphabet is 20 primitive kinds. There is deliberately no `RAII`, +//! `IteratorLoop`, `VirtualDispatch` or `Move` kind: a `lock_guard` local is +//! [`EventKind::Decl`] plus a type symbol, `std::move(x)` is +//! [`EventKind::Call`] plus a callee symbol. Those concepts are candidate +//! LEARNED tokens, and emitting them here would be writing a tokenizer's +//! answer into its input. Identities are carried verbatim, never hashed — +//! different consumers hash differently. +//! +//! # What libclang does not give +//! +//! There is **no CFG** in libclang's C API. `control` therefore carries only +//! structurally-certain relations (which construct a condition belongs to, +//! which arm a branch is, a loop's back edge, and — for `for` headers whose +//! own tokens spell exactly two semicolons — which of init/cond/inc a header +//! child belongs to). Successor/predecessor edges are not available and are +//! never fabricated. Every event also carries its source byte `anchor`, so +//! lexical order stays checkable against traversal order rather than being +//! silently conflated with it. + +use std::collections::BTreeMap; +use std::fmt; +use std::path::Path; + +use clang::source::File; +use clang::{Clang, Entity, EntityKind, Index}; + +use crate::clang_walker::{ + BodyArmConfig, assignment_target, bare_type_name, binary_operator_spelling, call_receiver, + method_body_arm, own_member_name, qualified_name, thrown_type_name, unary_operator_is_inc_dec, +}; + +/// The closed primitive alphabet.

In Flask and Django the navigation the user clicks AND the server-side +//! redirect are both authored **code-side**, in `.py`, as calls to `url_for` +//! / `reverse` / `redirect`. So a single AST body-walk over the parsed Python +//! finds every edge. **Rails, by contrast, splits navigation across two +//! artifacts** — the `.erb` view carries the `link_to` *click* edge, the `.rb` +//! controller carries the `redirect_to` edge — so the Ruby arm needs two +//! harvest shapes where Python needs one.

[`Visitor`], matching [`Expr::Call`] nodes. A call whose terminal callee is +//! one of `url_for` / `reverse` / `redirect` contributes a nav target **only +//! when its first positional argument is a string literal**; that string is +//! resolved to a screen stem (its leading segment before the first `.` or `:`) +//! and matched against a caller-supplied closed vocabulary of known screens +//! ([`NavVocab::screens`], tolerant of the singular/plural pairing +//! `project`↔`projects`). The matched screens become [`PyNavEdge`]s; the raw +//! count of every string-literal nav target seen — vocab member or not — is the +//! honest denominator [`NavScanReport::raw_target_refs`]. This is the same +//! closed-vocab + honest-denominator discipline the Ruby arm uses. +//! +//! # What is NOT captured (by design, not oversight) +//! +//! - **Dynamic / object targets** — `redirect(obj)` / `redirect(url_for(...))` +//! where the argument to `redirect` is a variable or a nested call, not a +//! string literal. The string literal is the only closed-vocab handle +//! without resolving the URL map / router, so a non-literal argument is a +//! dynamic target and is deliberately skipped (mirroring the Ruby arm's +//! dynamic-target exclusion). Note this leaves `raw_target_refs` untouched — +//! a non-literal target is not "a nav target seen", it is a target we cannot +//! read.

The navigation-topology harvest — the **Odoo Klickweg** (TWO shapes). +//! +//! # What this is +//! +//! The Odoo analog of the Flask/Django ([`crate::navigation`], ruff #63), +//! Rails (`ruff_ruby_spo`, ruff #62) and `WinForms` (`ruff_csharp_spo`, ruff +//! #61) `navigates_to` arms: it emits the shared [`Predicate::NavigatesTo`] +//! fact — `(source_screen, navigates_to, target_screen)` — feeding the same +//! `lance_graph_contract` screen-connectivity check +//! (`nav_is_fully_connected`). +//! +//! # Why Odoo needs its OWN shapes (the Flask arm is structurally blind here) +//! +//! Odoo's web client is a single-page app: business code never calls +//! `url_for` / `reverse` / `redirect` (measured on the real `account` addon: +//! 2 stray hits, all noise). Navigation is expressed as **window actions** +//! (`ir.actions.act_window`), and — like Rails, unlike Flask — it splits +//! across two artifacts: +//! +//! - **Shape A (code-side, `.py`)** — an `action_*`-style method returns a +//! dict literal `{'type': 'ir.actions.act_window', 'res_model': '<target>', +//! …}`. The edge is *(defining model → `res_model`)* — "a button on this +//! model's screen opens that model's screen". 42 such dicts in the real +//! `account` addon. +//! - **Shape B (data-side, `.xml`)** — a `<record model= +//! "ir.actions.act_window">` declares `res_model`, and a `<menuitem +//! action="…"/>` wires it into the menu. The edge is *(`menu` → +//! `res_model`)* — the synthetic `menu` root screen, giving the +//! connectivity check its entry points (18 action-carrying view files + +//! 52 menuitems in `account`). +//! +//! # Tier + doctrine (Inferred, closed-vocab, honest denominator) +//! +//! Shape A is **AST-based** like [`crate::navigation`] (parse with +//! `ruff_python_parser`, walk with the [`Visitor`]); Shape B is a stateful +//! line scanner in the `ruff_ruby_spo` ERB style (the XML surface is flat +//! `<record>/<field>/<menuitem>` markup — no XML dependency warranted). Both +//! shapes resolve targets against a caller-supplied closed vocabulary +//! ([`NavVocab::screens`]); every `act_window` occurrence seen — vocab member +//! or not — counts in the honest denominator +//! ([`OdooNavScanReport::raw_act_window_refs`]). +//! +//! Model names are normalized `.` → `_` (`account.move` → `account_move`), +//! matching the corpus IRI convention (`odoo:account_move`). Matching is +//! EXACT (no singular/plural tolerance): Odoo model names are canonical +//! identifiers, not route stems — `account_move` vs `account_moves` would be +//! two different models, so the Flask arm's plural tolerance would be a +//! false-positive source here, not a convenience. +//! +//! # What is NOT captured (by design, not oversight) +//! +//! - **Dynamic `res_model`** — `{'res_model': self._name}` or any non-literal +//! value: skipped (the dict still counts in the denominator), mirroring +//! every sibling arm's dynamic-target exclusion. +//! - **XML actions not wired to a menuitem** — a window action referenced only +//! from a `%(xml_id)d` button or returned indirectly is not a *menu* entry +//! point; its code-side counterpart is Shape A's job. Unwired records still +//! count in the denominator. +//! - **`ir.actions.server` / client actions / URL actions** — different +//! action families with different semantics; adding them is a deliberate +//! vocabulary extension, not a default. + +use std::fs; +use std::path::{Path, PathBuf}; + +use ruff_python_ast::visitor::{Visitor, walk_expr, walk_stmt}; +use ruff_python_ast::{Expr, Stmt}; +use ruff_spo_triplet::{Predicate, Provenance, Triple}; + +use crate::expr_str; +use crate::navigation::NavVocab; + +/// One Odoo navigation edge: `source` screen navigates to `target` screen. +/// +/// `source`/`target` are normalized model names (`account_move`), or the +/// synthetic `"menu"` root for Shape-B menu entry points. `via` records the +/// harvest shape for provenance: `"act_window_return"` (code-side dict +/// return) or `"menuitem"` (data-side XML join). +#[derive(Debug, Clone, PartialEq, Eq)] +pub struct OdooNavEdge { + /// The screen the edge originates from (normalized model name, or `menu`). + pub source: String, + /// The screen the edge opens (normalized `res_model`). + pub target: String, + /// Source file path relative to the scanned root (stable id, `/`-joined). + pub file: String, + /// The harvest shape: `"act_window_return"` / `"menuitem"`. + pub via: String, +} + +impl OdooNavEdge { + /// Lift this edge into the shared `navigates_to` SPO triple, namespaced + /// (`<ns>:<source>` → `<ns>:<target>`), `Inferred` tier — the same fact + /// shape the Flask, Rails and C# arms emit. + #[must_use] + pub fn to_triple(&self, namespace: &str) -> Triple { + Triple::new( + format!("{namespace}:{}", self.source), + Predicate::NavigatesTo, + format!("{namespace}:{}", self.target), + Provenance::Inferred, + ) + } +} + +/// Conservation-ledger totals for an Odoo nav scan (the honest-denominator +/// discipline — nothing drops silently). +#[derive(Debug, Clone, Copy, Default, PartialEq, Eq)] +pub struct OdooNavScanReport { + /// Every `*.py` file found under the scanned root. + pub py_files: usize, + /// Every `*.xml` file found under the scanned root. + pub xml_files: usize, + /// Every `act_window` occurrence seen — code-side dict literals plus + /// data-side `<record>` declarations — regardless of whether it produced + /// an edge.

The furnace playbook §8.1: *"Odoo +//! XML arch tags (`form`/`tree`/`kanban`) map to regions exactly like +//! `DockStyle`."* This arm makes that concrete — it reuses the SAME closed-vocab +//! predicates ([`Predicate::DockedAt`] / [`Predicate::TabOrder`] / +//! [`Predicate::OpensPopup`], [`Provenance::Authoritative`]), mints nothing. +//! +//! # The docking rule (arch element stack) +//! +//! Every leaf **control** (a `<field>` or a `<button>` in the view arch) docks +//! in its **innermost enclosing region container** — the nearest ancestor whose +//! tag is a region-bearing element ([`REGION_CONTAINERS`]): `<header>` / +//! `<sheet>` / `<searchpanel>` / `<footer>` / `<notebook>` / `<group>` / +//! `<form>` / `<list>` / `<kanban>` / `<search>` / the `oe_chatter` div. The +//! emitted dock TOKEN is that container's tag; a consumer `region=` config +//! (odoo-rs `data/nav/odoo_regions.conf`) maps the token → one of the six +//! canonical regions. Region NAMES never appear here — layout is not a domain +//! concept (two-axis mint refusal), so no token earns a codebook classid. +//! +//! The scan is **full-text, position-ordered** (like [`super::odoo_views`]) — +//! real Odoo XML wraps long tags across lines, so a line-based scan leaks.

Full wizard discrimination (an +//! `act_window target="new"` modal vs an in-place navigation) needs the +//! `act_window` join that [`super::odoo_nav`] already parses; that refinement +//! is the named follow-up, not fabricated here. +//! +//! # Extension views: the `inherit_id` join +//! +//! An **extension view** (`<field name="inherit_id" ref="…"/>`) does not carry +//! a full arch. It patches its parent with **locators**: an `<xpath +//! expr="…" position="…">` element, or the shorthand form, any element that +//! carries a `position` attribute (`<field name="amount" position="after">`). +//! A missing `position` means `inside`, as in Odoo: on any `<xpath>`, and on a +//! named `<field>` at the top level of an extension's arch. A shorthand +//! locator with any attribute besides `name`/`position` is left unresolved +//! (Odoo matches on all of them; only `name` is tracked). +//! A locator is never a control itself. The controls it brings dock in the +//! parent's region at the locator's TARGET: +//! +//! - `after` / `before` / `replace` → the region the target sits in; +//! - `inside` a region container → that container's token; +//! - `inside` a `<field>` → the field's comodel subview, so not docked (the +//! depth-0 rule); +//! - `attributes` → no controls. +//! +//! A container opened INSIDE the locator block still wins for the controls it +//! wraps (a new `<group>` docks its fields at `group`). Targets resolve against +//! the parent's anchors, then its own parent's, up the `inherit_id` chain, so +//! an extension of an extension resolves through what the first one added; +//! a later spec also resolves through what an earlier spec in the same view +//! added. References join on the module-qualified xml id (an unqualified +//! `ref` is qualified with the declaring module, the first path component +//! under the scanned root); when no scanned view has that exact id, the +//! local part is accepted only if exactly one scanned view carries it. +//! +//! Only `name`-addressed or bare-tag targets resolve (`//field[@name='x']`, +//! `//sheet`); an xpath whose last step filters on anything else +//! (`[hasclass(…)]`, `[@string=…]`, positional) is left unresolved rather than +//! matched to the first element of that tag. An unresolved locator (unknown +//! target, or a parent outside the scanned root) docks its controls at the +//! honest fallback token `"root"`, which the consumer `region=` config maps to +//! the main content region (`root:center`). +//! +//!

Odoo `ir.ui.view` field-set extractor — the presentation-tier harvest, +//! **fourth skin**. +//! +//! # One brick, four skins +//! +//! ERB (Rails), askama (Rust), Jinja/Django (Python, [`crate::templates`]) and +//! **Odoo view XML** (this module) are renderers over the **identical** +//! `WideFieldMask` projection: a consumer takes the field SET this harvest +//! produces and mints the mask via +//! `WideFieldMask::from_universe_present(basis, fields)`. This is the Odoo +//! source of that mask — the upstream (frontend-crate) home of the harvest +//! odoo-rs's `view_mask.rs` prototyped consumer-side against the real +//! `account_move_form_view.xml`. +//! +//! # Why record-scoped, not receiver-scoped (the ONE structural divergence) +//! +//! A Jinja/ERB template references fields through a context variable, so the +//! sibling arms need a caller-supplied *receiver* vocabulary. An Odoo view +//! **binds its model in the artifact itself**: the `<record model="ir.ui.view">` +//! block declares `<field name="model">account.move</field>` and then its +//! `arch` names the projected fields as `<field name="partner_id"/>`. So this +//! arm matches on the record's own declared model and [`ViewTarget::receivers`] +//! is deliberately ignored (documented, not silently) — the artifact IS the +//! receiver. Everything else — the [`ViewTarget`] / [`ViewFieldSet`] +//! vocabulary, presence-only doctrine, closed-vocab `fields` + raw +//! `referenced` honest denominator — is byte-aligned with the sibling arms. +//! +//! # The meta-field / arch-field split (the scanner's ONE load-bearing rule) +//! +//! Inside a view record, `<field name="model">` / `<field name="arch">` / +//! `<field name="inherit_id">` etc. are META fields describing the view — NOT +//! model fields the view projects. The projected fields live INSIDE the +//! `arch`. The scanner therefore only starts collecting `<field name="X"` +//! occurrences AFTER the `<field name="arch"` line of the current view +//! record, and stops at `</record>`. An inherit-view's xpath-positioned +//! fields live inside its arch too, so extension views harvest the same way. +//! +//! # Doctrine (identical to the sibling arms) +//! +//! Presence-only (fuzzy-recipe-codebook §8c "detected config becomes data"): +//! the field SET, never layout/widgets/attrs. Inferred tier. A field is +//! recorded into [`ViewFieldSet::referenced`] unconditionally and ADDITIONALLY +//! into [`ViewFieldSet::fields`] when it matches the target's closed +//! vocabulary — `fields ⊆ referenced` by construction. +//! +//! # What is NOT captured (by design, not oversight) +//! +//! - **`QWeb` report templates** (`t-field="o.partner_id.name"` in +//! `ir.actions.report` XML) — the PDF/report skin is a receiver-style +//! reference surface (like Jinja) with its own idioms; adding it is a +//! deliberate extension, not a default. +//! - **Widget/attrs semantics** — `widget="monetary"`, `invisible`, +//! `readonly` modifiers: presentation, not projection membership. +//! - **Nested (relation-hop) sub-fields** — a field element nested inside +//! another (`<field name="invoice_line_ids"><field name="quantity"/> +//! </field>`) names a COMODEL field, not a this-model field; the depth-0 +//! rule excludes it from `referenced` (counting it would poison the mask +//! whenever names collide across models — `date` exists on both +//! `account.move` and `account.move.line`).

This module is the +//! **Jinja source** of that mask — the direct sibling of `ruff_ruby_spo`'s ERB +//! `views.rs`, with the same `ViewTarget` / `ViewFieldSet` vocabulary so the +//! three skins stay aligned across frontends. +//! +//! # Doctrine (fuzzy-recipe-codebook.md §8c — "detected config becomes data") +//! +//! A Jinja/Django template is a **detected configuration artifact**: it names, +//! via `<receiver>.<field>` references, exactly which model fields a route +//! projects to the user. Per the config-as-data rule, that artifact becomes a +//! **data input to the codebook** — the referenced field SET — never code to +//! transcribe. We do NOT parse Jinja structure, walk template expressions, or +//! reproduce layout/markup. The only fact recorded is *presence*: does this +//! template, anywhere, reference `<model>.<field>`? Two templates projecting +//! the same ten fields in different table layouts are identical for this +//! purpose. +//! +//! # Why a line scanner in an AST crate +//! +//! The rest of this crate is AST-based (via `ruff_python_parser`) because its +//! inputs are Python source.

Scanning +//! lines for `<receiver>.<ident>` automatically catches references inside +//! `{% if obj.field %}`, `{{ obj.field|date }}`, and `{% for x in obj.items %}` +//! — presence is presence, matching the ERB arm's "helper-wrapped reference is +//! still captured" stance. A filter (`obj.field|filter`) comes AFTER the +//! identifier, so the ident charset scan already terminates before the `|` and +//! `field` is captured. +//! +//! # Tier: Inferred, by construction +//! +//! A reference is only recorded when BOTH the receiver identifier and the +//! field identifier match caller-supplied closed vocabularies +//! ([`ViewTarget::receivers`] / [`ViewTarget::fields`]) — this bounds false +//! positives at the cost of requiring the harvest stratum (schema + +//! declarations) to already know the field list. It is Inferred, not +//! Authoritative: `{{ project.name|upper }}` and a bare `{{ project.name }}` +//! are indistinguishable here (both project the field, which is all this +//! stratum claims). +//! +//! # What is NOT captured (by design, not oversight) +//! +//! - **Presentation** — HTML structure, CSS classes, i18n strings, +//! conditionals, loops. Only the field-name SET, per the doctrine above. +//! - **Multi-hop chains** (`project.owner.name`) — only the first hop off a +//! registered receiver is read; `owner.name` is a second, independent +//! reference the caller registers under its own [`ViewTarget`] if it wants +//! it captured. +//! - **Jinja expressions/macros** — `{% macro %}` bodies, `set` locals, and +//! arbitrary expressions are not evaluated; only textual +//! `<receiver>.<ident>` presence counts. +//! - **Template inheritance resolution** — `{% extends %}` / `{% include %}` +//! are not followed; each file is scanned independently. A field projected +//! by a parent layout is attributed to the parent's file, not the child's. +//! +//! # The honest coverage denominator (`ViewFieldSet::referenced`) +//! +//! A `coverage = |known| / |referenced|` metric needs the RAW distinct +//! `<receiver>.<ident>` references as its denominator, not just the subset +//! that happens to already be in the harvested field vocabulary — otherwise +//! coverage is trivially `1.0` (every hit counted is, by construction, a +//! known hit). [`ViewFieldSet::referenced`] is that raw set: every distinct +//! identifier seen immediately after a *registered* receiver + `.`, +//! regardless of vocabulary membership. [`ViewFieldSet::fields`] stays the +//! known subset — `fields ⊆ referenced` always holds (enforced by +//! construction: a candidate is recorded into `referenced` unconditionally, +//! then additionally into `fields` when it matches the vocabulary). +//! +//! Note: unlike the ERB arm, the identifier charset here is plain +//! `[A-Za-z0-9_]` — **no `@`**, which is a Ruby ivar concept with no +//! Python/Jinja counterpart.

A persisted code/data map would be exactly the second truth this whole arc exists to remove. +//! A future dynamic arm (observing real `MemRead`/`MemWrite` during execution) is a different +//! rung: it is NOT derivable from the image, two runs disagree, and it may legitimately be +//! stored as evidence. This probe deliberately contains only the derivable half. +//! +//! ## The measured edge case, and why it is the best falsifier +//! +//! Elite has **zero `JMP ($xxxx)`** — the worst enemy of static analysis is absent. But it does +//! have jump tables (`JMTB`, plus two music-command tables), dispatched by index. Recursive +//! descent cannot follow those, so table-only-reachable code lands in the unreached set and looks +//! like data. That is not a flaw to route around: a jump table is genuinely a data table whose +//! VALUES are code entry points — one region, two legitimate readings — and it is the case a +//! ClassView has to express without a `this_is_a_jump_table` flag. +//! +//! ## KILL CONDITION, pre-registered +//! +//! If the code images come back **>= 95% reached**, reachability cannot discriminate either (it +//! marks nearly everything), and this probe reports that instead of proposing a rule. Likewise if +//! the data controls do not sit clearly below the code images. +//! +//! ## Seeding — the load address is NOT the entry point (measured) +//! +//! A first version seeded the descent at the load address and reported **0.0% reached, 1 +//! instruction** on every subject. That was a broken probe, not a result: `gma5` begins with +//! `$00` = BRK, which lifts to an immediate stop, and the others halt within one instruction. +//!

Elite's `gma4/5/6` images are ENCRYPTED — the game's own `elite-checksum.asm` ("COMMODORE 64 +//!

On decrypted plaintext the picture INVERTS: decode-error +//! rises to **87.6%** balanced accuracy while control-flow density FALLS to **60.8%**.

A +//! "counterintuitive keeper" recorded at the time — that DATA shows higher control-flow density +//! than code — is false on real code. +//! +//! This probe asks whether the two populations can be told apart, and answers it with a +//! **control group rather than a heuristic**: Elite ships files that are known-pure-data +//! (`SHIPS.bin` ship blueprints, `WORDS.bin` text tokens, `LODATA.bin`, `IANTOK.bin`, +//! `SPRITE.bin`) alongside files that are known-pure-code (`LOCODE.bin`, `HICODE.bin`, which are +//! `gma5.bin`/`gma6.bin` minus their 2-byte PRG header).

Cause: +//! it handed every sweep block to ONE `FunctionBehavior`, and `CFG::from_blocks` keeps only the +//! component reachable from `blocks[0]`, so those columns measured a tiny entry-reachable +//! fragment rather than the file. The columns were removed rather than reported. What remains +//! comes straight off the sweep and needs no SSA. The real question is also per-REGION, not +//! per-file: a whole-file aggregate over 8 KB averages code and data together, which is exactly +//! the blur the partition has to see through. +//! +//! **The premise this probe was built to serve turned out to be FALSE, and the probe is what +//! showed it.** It was written believing `harvest_6502` had lifted Elite's ship blueprints and +//! market tables as opcodes, contaminating its residual rows. It had not: Elite keeps data +//! in a SEPARATE source file (`elite-data.asm` → `SHIPS.bin` / `WORDS.bin` / `LODATA.bin` / +//! `IANTOK.bin`), and the harvest corpus was `gma4/5/6` = COMLOD / LOCODE / HICODE, all code. +//!

The near-identical shape at `$1d2d` is the one that must NOT count: +//! +//! ```text +//! IntSub { dst: Unique 19584, a: Register 34, b: Const 1 } ; stack pointer - 1 +//!

Same `Store`-through-a-temp silhouette, and its constant (`1`) is an offset from a +//! register rather than a base address.

For each `Load`/`Store`, resolve its address operand: +//! +//! - `Const` — the address, directly. (Zero page and the hardware vectors arrive this way.) +//! - `Unique` — find the **nearest preceding op that writes that temp**, via +//! [`R2ILOp::output`], and accept only an `IntAdd` carrying a constant.

Stage 2 — the **ore**: deterministic typed fact enumeration over the object graph. +//! +//! > **"Varnode in the first stage is pointer chasing stacked god objects — hence the ore +//! > furnace slag."** (operator, 2026-08-18) +//! +//! The upstream object graph [`crate::behavior::FunctionBehavior`] carries — a private +//! `HashMap`, a petgraph CFG, `BTreeMap` keyed by +//! String-carrying vars, facts as nested `BTreeMap`s of structs — is GOOD ORE and structurally +//! still stage-1 pointer chasing. **Typed ≠ refined.** Mistaking the cleanliness of r2il's Rust +//! types for refinement *is* the privileged-direct-path the pivot forbids. This module *reads* +//! that graph and emits typed [`OreFact`] rows; it does **not** flatten (that is +//! [`crate::furnace`]) and it does **not** classify (that is [`crate::convention`], applied by +//! [`crate::furnace`]). +//! +//! # The load-bearing consequence: the facet coordinate is NOT recoverable from SSA +//! +//! `SSAVar` carries `name` / `version` / `size` and **no offset and no `SpaceId`**. The only +//! SSA-side trace of a varnode's offset is inside its *display name* (`"reg:10"`, +//! `"space7:1000"`) — and parsing display strings is forbidden as a data path +//! (`format!("{:?}")` is FORBIDDEN as a data path throughout this crate). Therefore +//! [`enumerate`] takes BOTH the [`crate::behavior::FunctionBehavior`] AND the source +//! `&[R2ILBlock]`: operand coordinates come from the **typed** [`Varnode`]s in the source ops, +//! joined to SSA instructions by the `(block_addr, op_idx)` key +//! `SsaGraph::op_inst_by_site` / `op_site_by_inst` provide. +//! +//! The join is **verified, not assumed**: at each `InstPayload::Op` site we compare +//! `OpTag::from_op(ssa_op)` (what SSA expects at this site) against `OpTag::from_r2il` of the +//! r2il op actually found at the joined `(block_addr, op_idx)` (what the source actually has). A +//! mismatch — the `Multiequal` index shift (a phi extracted from `.ops` into `.phis` leaves a +//! later r2il op's `.ops` index pointing at what SSA calls a different instruction), or a +//! `CallDefine` insertion (a synthetic op with no r2il counterpart at all, shifting every later +//! index) — emits [`OreFact::JoinFailure`], **never** a silently misattributed coordinate. +//! +//! Rows with no source varnode at all — phi inputs (routed through the dedicated +//! [`OreFact::PhiInput`], which carries no facet-coordinate fields to misattribute) and +//! `SSAOp::CallDefine` (a fresh unknown-register value with no source op whatsoever, so no join +//! is even attempted for it) — are the furnace's `NoFacetCoordinate` residual once melted; this +//! module simply never manufactures a coordinate for them. Nothing is dropped: every +//! `InstPayload` produces an [`OreFact::Op`] row regardless of whether its operand coordinates +//! could be recovered. +//! +//! # `FactProvenance.value` convention +//! +//! [`FactProvenance::value`] is "the single [`ValueId`] this particular row is most directly +//! about, if any": an [`OreFact::Op`] row carries the instruction's own output (the value it +//! defines); an [`OreFact::Operand`] row carries that operand's own value (duplicating the +//! variant's own `value` field so a generic consumer that only inspects `prov` still sees it); +//! an [`OreFact::PhiInput`] row carries that input's value; an [`OreFact::Predicate`] row +//! carries the branch condition; an [`OreFact::CallSite`] row carries the call target; +//! [`OreFact::MemoryUse`] / [`OreFact::MemoryDef`] leave it `None` (a memory fact's identity is +//! an `ObjectId`, a distinct fact-space from a single SSA value). +//! +//! # Enumeration order — fixed and documented (the determinism guarantee) +//! +//! 1. **Blocks** in [`SSAFunction::block_addrs`] order (reverse postorder, a `Vec` — *never* the +//! private `HashMap`). +//! 2. **Within a block**, `GraphBlock::insts` order (phis then ops, each in `GraphInst::ordinal` +//! order — already the construction order upstream; never re-sorted here): +//! - a `Phi` payload emits one [`OreFact::Op`] (`opcode = OpTag::Phi`) and nothing else at +//! this step (no join target exists for a phi); +//! - an `Op` payload emits one [`OreFact::Op`], then — unless the op is `SSAOp::CallDefine` +//! (no source op exists at all) — attempts the op-site join: on a tag match, one +//! [`OreFact::Operand`] per source-op input (in `R2ILOp::inputs()` order) then one for the +//! output if present; on a tag mismatch, one [`OreFact::JoinFailure`]; if no r2il op exists +//! at the joined site at all (an index-shift landed past the end of the source block), +//! neither is emitted — the [`OreFact::Op`] row already stands for the instruction. +//! - then, once every inst in the block has been visited: one [`OreFact::Edge`] per +//! `GraphBlock::successors` entry, in that `Vec`'s order; +//! - then one [`OreFact::PhiInput`] per phi source, for every phi in the block, in phi-then- +//! source order. +//! 3. **Then, function-wide** (every container touched is a `BTreeMap` — deterministic key +//! order, never a `HashMap`): +//! - [`OreFact::MemoryUse`] then [`OreFact::MemoryDef`], both by ascending [`InstId`] +//! (`MemorySSAFacts::uses_by_inst` / `defs_by_inst` are already `BTreeMap`); +//! - [`OreFact::Predicate`], by ascending [`PredicateId`] (`PredicateFacts::predicates`); +//! - [`OreFact::CallSite`], by ascending [`CallSiteId`] (`CallSiteFacts::by_id`). + +use r2il::{R2ILBlock, R2ILOp, SpaceId}; +use r2ssa::{ + BlockId, BlockTerminator, CallSiteId, CompareKind, InstId, InstPayload, ObjectId, PredicateId, + SSAOp, ValueId, +}; + +use crate::behavior::FunctionBehavior; + +// ============================================================================================ +// OpTag +// ============================================================================================ + +/// One variant per `SSAOp` variant.
