…on (#3192) (#3193) `check-clash-degenerate-reason-parity.mjs` printed one fixed header and one fixed epilogue for every failure it could raise, including the vacuity class where its own extractor came back empty. For that class both were wrong. The header claimed `ClashSolidDegenerateReason has drifted from clash_solid.rs` when nothing had drifted -- the gate simply could not read one of its inputs. The epilogue then said to update the union "to match clash_solid.rs exactly, in both directions". With the kernel set read as empty that instruction means EMPTY THE UNION, which silences the gate and breaks the type every `as ClashSolidDegenerateReason` cast on the wasm boundary depends on. A gate whose remedy destroys the thing it guards is worse than no gate. `checkParity` already returns early on the vacuity class, so vacuity and the missing/phantom classes are mutually exclusive and a two-way dispatch on the header and the remedy is unambiguous. The remedy names no culprit side. Emptying an input produces the identical "the extractor has drifted" message with the regexes untouched, so a moved source shape and a genuinely shrunken input are indistinguishable from inside the script; it says so and points the reader at the input instead. The vacuity GUARD itself was already correct and is untouched -- an empty set has always failed the gate closed. This is a reporting defect only: the gate went red for the right reason and then gave destructive advice. Two self-test cases pin both directions: the vacuity path prints the neutral header and does NOT print the update-the-union remedy, and a real parity failure still does. Verified RED against the pre-fix script. CI-only script change, so no changeset: no published package behaviour moves. Found while reviewing #3191, which fixes the same shape in `check-legacy-entity-coverage.mjs` and cites this script as its model.
… gate that would have caught one itself is correct and unchanged here; what did not land is the review, and three of its findings were claims the code does not support. 1. The changeset says `IfcDoorStyle` and `IfcWindowStyle` were affected and implies this change fixes them. It does not. Both carry `has_geometry: false` in `legacy_entities.rs`, and `styling/prepass.rs:177` plus its siblings in `gpu_meshes/prepass.rs`, `processing/shard_classes.rs` and `processing/processor/mod.rs` gate type-geometry candidates on a bare `IfcType::from_str(name).is_subtype_of(IfcTypeProduct)`, which is false for any keyword IFC4X3 dropped. Both are discarded before a job exists, so they never reach the corrected line. The changeset text ships as the changelog and #3186 has not published yet, so this is correctable in place. #3187 tracks the nine sites. 2. `batch.rs` justified the unvalidated `content.get(start..end)` with "`content[start..end]` is the record `decode_and_cache` just parsed". False on the cache-hit path: `decoder.rs:443` returns the cached `Arc` without reading `start`/`end`, so only the miss path bounds-checks them. Narrowed to the span the job carries, with the fail-soft behaviour stated. 3. A test docblock said the six #3172 entities were "deliberately absent" because #3172 "is still in review". #3172 merged; the sentence was true when written and false on merge. The gate that would have caught the first one, derived rather than transcribed: `check-legacy-entity-coverage.mjs` already extracts the legacy arm keys and the generated `from_str` names from source and never intersected them. An arm whose key `from_str` already resolves makes the `Unknown` short-circuit in `legacy_aware_ifc_type_from_record` skip the remap, reopening exactly the wasm-vs-native divergence #3179 was filed for. Now checked, with a mutation case proving it fires. Also from the review: a Rust test pinning the same invariant behaviourally (it calls `from_str` for real, where the gate reads source text); a contract test for `extract_entity_type_name` next to the function rather than only in its caller's tests; one shared `LEGACY_KEYS` so the two opposite-direction tests cannot drift; a dead `type_end <= type_start` guard removed (`paren_pos >= 1` always, the one reachable equality is the empty slice `is_empty` already rejects); and three dead or duplicated items in `test-wasm-contract.mjs`. Every new test mutation-verified in both directions.

Drafted deliberately. Not because it is unfinished, but because "do not merge this yet" has so far only been an intention of mine, and an intention is not a gate. #3182 was merged out from under its own review earlier tonight, from a commit that predated the review that was running against it. This PR exists to repair the three claims that slipped through as a result. Shipping it the same way would be a poor joke. There are currently seven Claude sessions active on this machine. Lane claims cover three of them. The draft flag covers all seven. Undraft when Louis has decided it should land. Everything else about it is ready: the diff is frozen at 344a54a, it merges into origin/main with zero conflicts, and it has been through eleven /simplify and sixteen /code-review passes. |

@coderabbitai full review Requesting a fresh review at the current head. The existing review is at Flagging for humans reading this: the PR is drafted deliberately, and CodeRabbit does not auto-review drafts by default. That means the draft gate would otherwise starve the review it is waiting for, which is why this is a manual trigger rather than an undraft. If no review appears, the correct response is to re-trigger, not to undraft. |

Correct the *StandardCase arm count.
Line 7 says that eight *StandardCase variants are legacy arms. LEGACY_KEYS contains seven such keys. This changeset will misdescribe the released coverage.
Proposed fix
- the eight `*StandardCase` variants
+ the seven `*StandardCase` variants📝 Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Thanks for the re-review at head. One actionable finding, and I am rejecting it with evidence rather than applying it. Finding: correct the changeset's There are eight, not seven, in both places. Measured at I also checked the one reading where "seven" could be right in substance. The sentence says the 22 arms that carry geometry are fixed, so a One note on where No change made. The count stands at eight. |

#3182 was merged from a commit taken before its review passes finished. The functional fix landed correctly and is unchanged here. What did not land is the review, and three of its findings were claims the code does not support. Two of them are still on
main; one of those ships as a changelog.The three claims
1. The changeset says
IfcDoorStyleandIfcWindowStyleare fixed. They are not.Both carry
has_geometry: falseinlegacy_entities.rs:77,81, andstyling/prepass.rs:178plus its siblings ingpu_meshes/prepass.rs,processing/shard_classes.rsandprocessing/processor/mod.rsgate type-geometry candidates on a bareIfcType::from_str(name).is_subtype_of(IfcTypeProduct)— false for any keyword IFC4X3 dropped. Both are discarded before a job exists, so they never reach the line #3182 corrected.This matters beyond tidiness: the changeset text ships as the changelog, and #3186 has not published yet, so it is correctable in place. #3187 enumerates the other sites.
2.
batch.rsjustified an unvalidated slice with a claim that is false on one path.It read "
content[start..end]is the recorddecode_and_cachejust parsed". On a cache hitdecoder.rs:443returns the cachedArcwithout ever readingstart/end, so only the miss path bounds-checks them. Narrowed to the span the job carries, with the fail-soft behaviour stated.3. A test docblock said the six #3172 entities were "deliberately absent" because #3172 "is still in review". #3172 merged. True when written, false on merge.
The gate that would have caught the first one
check-legacy-entity-coverage.mjsalready extracted the legacy arm keys and the generatedfrom_strnames from source and never intersected them. An arm whose keyfrom_stralready resolves makes theUnknownshort-circuit inlegacy_aware_ifc_type_from_recordskip the remap, reopening exactly the wasm-vs-native divergence #3179 was filed for.Now checked, derived from source rather than transcribed, so a 27th arm added later is picked up automatically.
The same gate printed the wrong remedy for its own failures: one fixed epilogue told the reader to add an arm for a failure whose fix is to remove one. Now four per-class remedies plus a neutral header for the extractor-drift class, which previously claimed the table was out of step when the check had simply gone blind.
Also from the review
