Conversation
Implements #660, Slice C. Madar activated a set of behaviours whenever a prompt merely LOOKED like the qualification report-generation task. Over a repository with no such structure, report vocabulary alone pulled the retrieval gate to runtime_generation and made the pack assert a planner/research/assembly/scoring/rendering/persistence workflow that no evidence supported. Removed from exactly three production files: - prompt-pack.ts: the `promptWantsReportGenerationCore` task-phrase classifier, the fixed report workflow instruction, and a phase-label table whose five keys no contract builder anywhere in the repository ever emitted. Instructions are now derived from the typed `answer_contract` alone, so the question text is no longer an input to instruction generation at all. - retrieve/slicing.ts: the duplicated classifier, the `semanticGenerationCoreAnchorValue` name-driven score table, forced anchor membership and its `generation core heuristic` reason, the raised anchor cap, the report-only deep backward slice policy, the report-only route-predecessor suppression, and report-stage and qualification-repository vocabulary in the node-name and prompt classifiers. - retrieval-gate.ts: the `reportGenerationShaped` variant. Gate outcomes now follow generic evidence only. `report_generation_shaped` is retained as a constant `false`. It is a required member of the published `RetrievalGenerationDebugSignals` shape, so removing it would need a fourth production file and an artifact-schema change; the true branch is unreachable and nothing reads it to reach a gate outcome. Generic behaviour is preserved and measured, not assumed. `persistence` stays in the runtime-pipeline prompt classifier because removing it regressed a neutral login/persistence fixture that contains no report vocabulary; the report-stage names did not come back. The typed answer-contract instruction path is byte-identical before and after, and the pre-existing prompt-pack parity golden is unchanged. Tests that locked the removed behaviour are converted into independence controls rather than re-snapshotted, and a new control file proves that report vocabulary, report-shaped symbol names and report-shaped paths each buy nothing. Four focused injections restore one retired rule apiece from a digest-checked byte snapshot and require the named control to fail. The forbidden-knowledge manifest gains six narrow distinctive rules. The scanner parsing architecture, static evaluator, regex capability boundary, normalization model and production-exception policy are unchanged. #660 remains open until Slice C is merged and post-merge verified. #661 is not started.

Bounded correction to #660, Slice C, from the FINAL review. `genericGenerationShaped` still listed `assembl(e|ed|es|ing)`. Assembly is one of the six declared report workflow stages, and it was the only one of the six that could reach a runtime-generation gate on its own: Explain planner -> unknown Explain research -> unknown Explain assembly -> unknown Explain scoring -> unknown Explain persistence -> unknown Explain assemble -> runtime_generation / backend_runtime Measured against the built candidate, `assemble` behaved identically to `generate`, `create`, `build` and `produce`, so it was acting as a member of the generic generation-verb family rather than as a report signal. The asymmetry across the six stages is real all the same, so the token is removed rather than argued away. The remaining verbs carry the generic sense without naming a report stage, and an assembly question with real backend evidence still classifies: How is the response assembled by the worker pipeline -> runtime_generation How is the invoice assembled and saved to the repository -> runtime_generation Explain how the bundle is assembled -> unknown The last line is the intended cost, and it is the same answer the other five stage words already gave. Control A missed this because its minimal pair already carried the generic verb "generated", so a stage word reaching the gate through the generic list stayed invisible. New control A2 walks the six stages one at a time, asserts the generic display classifier still owns `rendering`, and fails in both directions by requiring the same words to earn a runtime gate once backend evidence is present. Production scope is unchanged at three files.
…e-credit path Resolves both PR review threads on #660 Slice C. Two verified defects, both in the evidence the slice rests on. 1. `research` was still earning runtime-expansion preference. Slice C removed the report stage names from `pipelineBridgeLikeNode` and `highValueRuntimeExpansionNode`, but those patterns anchor only their first and last alternatives, so the unanchored `search` matched the tail of "research" and the removal was silently defeated. Measured: `.researchStep()` in `/src/flow/research.service.ts` still classified as a high-value runtime expansion node. `persistence` likewise still matches through `persist`. `search` is now anchored on its left. The other terms keep their existing loose anchoring deliberately — they are meant to match inflections such as "workers", "jobs" and "pipelines", and tightening every alternative would change generic ranking well beyond this slice. `persist` deliberately still matches "persistence": it is a generic runtime verb naming an ordinary backend layer, already judged generic in this slice when removing it from the prompt classifier regressed a neutral login fixture. The rule is that a report stage NOUN confers nothing while a generic runtime VERB may. New control C3 covers the path that let this through. Control C never reaches these classifiers, because they run only under a runtime-flow-only forward policy. C3 drives the slicing entry point with an exact symbol anchor and observes INCLUSION rather than ordering — a third hop is reachable only if the middle node earned the preference. Verified in both directions: it fails with the leak restored and passes with it closed, from a digest-checked snapshot. 2. The injection harness could hand out credit it had not earned. It ran each control only AFTER mutating the source. A control that was already red would therefore have made every injection look successful, since the failure would not have been caused by the injection. Each injection now requires the named control to be GREEN before the mutation and RED after it. Production scope is unchanged at three files.

Implements #660, Slice C.
Slice A (PR #730, squash
25ae7391) and Slice B1 (PR #731, squash8f05be8c) are already merged and post-merge verified. This is the final authorized slice; there is no Slice D.What was wrong
Madar activated a set of behaviours whenever a prompt merely looked like the qualification report-generation task. Measured on the base tree by running the built entry points over a repository with no report structure at all (a two-node theme-toggle/colour-store graph), the words alone bought:
runtime_generation/backend_runtimelevel 3, despitebackend_runtime_shaped: falseanddisplay_shaped: true;Follow planner, research, assembly, scoring, rendering, and persistence evidence before concluding the flow.— with no evidence behind it.On a five-stage flow asked with equivalent intent, report wording returned 5 nodes and two forced
generation core heuristicanchors where neutral wording returned 2 nodes and one ordinary lexical anchor.Stage 0 occurrence sites and disposition — 18

report_generation_shapedis retained as a constantfalse, not deleted. It is a required member ofRetrievalGenerationDebugSignals(src/contracts/retrieval-gate.ts:48) and is emitted into the pack, so deleting it needs a fourth production file and an artifact-schema change — both out of bounds. The true branch is unreachable and nothing reads it to reach a gate outcome. Consequence: the manifest deliberately carries noreportGenerationShapedrule, becausesquashFormmaps both spellings to the same needle and it would match the retained field.

Removing
persistencefrom the runtime-pipeline prompt classifier broketests/unit/retrieve-slice-v1.test.ts— "treats direct controller-to-store flows as complete when persistence is reached without queue work" — a neutral login prompt containing no report vocabulary. That is a genuine generic regression, sopersistencewas restored: it names an ordinary backend layer, the retained genericbackendRuntimeShapedgate signal already treatspersistas a backend marker independently of the prompt, and a pre-existing non-qualification fixture exercises it. The report-stage namesscoringandreport builderdid not come back.The typed answer-contract instruction path is byte-identical before and after for both neutral and report wording, and the pre-existing parity golden is unchanged.

No fixed workflow, no forced anchor, no gate variant.Existing tests that locked the removed behaviour were converted into independence controls, not re-snapshotted:
compare.test.ts(fixed instruction),retrieval-gate.test.ts(the gate variant — now paired with the test directly above it), four inretrieve-production-correctness.test.ts(forced anchor, name preference, backward flow, compaction), and one inpack-quality-fixtures.test.ts(thequality gate+10 promotion). Each rewrite records why in place.Falsifiability — 4/4

Six narrow distinctive rules added to the existing manifest. Zero Slice-C matches at head; 14 occurrences at base with all six rules firing — every rule catches its own mutation. A seventh candidate (
report_builder_phase) was dropped, not excepted: it collided with a legitimatemissing expected report builder phasemessage inretrieve.ts, and production exceptions are forbidden.tests/unit/production-independence.test.tsuntouched; no scanner timeout increase.Local qualification

The maintainer, not this PR, decides whether the verdict carries to the corrected head.Re-qualified at

The inventory unit is the exact production source occurrence site.
Final production occurrence sites: 21
src/infrastructure/prompt-pack.tssrc/runtime/retrieve/slicing.tssrc/runtime/retrieval-gate.tsThe three review-added sites represent two post-review defect classes:
retrieval-gate.ts— theassembl*token ingenericGenerationShaped.retrieve/slicing.ts— the unanchoredsearchalternative inpipelineBridgeLikeNode.retrieve/slicing.ts— the unanchoredsearchalternative inhighValueRuntimeExpansionNode.Sites 2 and 3 share one defect mechanism but are separate production sites, which is why the site count (3) exceeds the defect-class count (2).
An earlier draft of this section published a total of 20 under a
4 / 13 / 3allocation. That was withdrawn as both arithmetically and attributionally wrong:slicing 13requires counting the leak as two sites, which forces the total to 21 rather than 20; and theassembl*occurrence belongs toretrieval-gate.ts, notslicing.ts— commita0a7640ctouched exactly one production file,src/runtime/retrieval-gate.ts.Category totals use a different unit
Category figures group by policy, not by source site, so they are deliberately not reconciled against the 21-site inventory — the units differ and the categories are not mutually exclusive.
Fixed instructions removed: 2, plus the dead five-key phase-label table. Task-phrase classifiers removed: 3. Report-specific gates removed: 1. Generic replacements: 1. Disguised replacements: 0.
