fix(retrieval): remove explicit qualification tuning (#660-B1) - #731
Conversation
Implements #660, slice B. Slice A (#730) established the structural grader/runtime boundary; this removes the tuning that was fitted to particular qualification repositories from retrieval and claims. Production: 3 files, net -294 lines. The re-derived inventory found knowledge of TWO qualification repositories in production, not one, and the historical "37 matches" figure was superseded by an artifact-derived count of 45 occurrences across exactly the three sanctioned files. Removed - Three fixed claim builders keyed on one repository's paths, symbols and snippet shapes: "public runtime provenance", "public payload divergence", "failure detection" / "cross-runtime handoff". - Eight repository-shaped snippet patterns and the two fragment extractors built on them, four score-ladder rows, a low-value-line exemption, a forced line removal, and two copies of an eleven-slot reserved-pattern array (reduced to the four generic shapes). - A fourteen-symbol denylist and a per-symbol promotion/demotion table belonging to a second repository. - Vendor API names (createTask, NewClient) inside otherwise generic verb lists; NewClient is now covered by the language constructor idiom it stood in for, which matches both Go and TS spellings. - A per-question source-domain carve-out, a benchmark question phrase, a symbol-naming-convention penalty, and task-domain vocabulary in the runtime-stage value table. - Three literal repository paths and four repository symbols from the demotion patterns, two repository directory names from two layer patterns, and a question-phrasing stop list. - The task-phrase class the first inventory missed: the public+page obligation rules, the forced HTTP-boundary reservation, and the cross-runtime forced selection that overwrote an obligation's preferred anchor. Replaced One generic claim builder driven by typed evidence: relationships the extractors recorded (enqueues_job, handles_route, registers_route, declares_controller, renders, ...) and framework-declared roles. It cites both source locations and names the relation that produced the claim, and it never reads a snippet, so no amount of matching text can conjure a claim. buildInputProvenanceClaims is retained: RouterOutputs is a framework type helper any tRPC repository defines. Measured consequence, recorded rather than papered over With the reservation gone and no generic signal reserving it, a framework-declared route handler is no longer force-selected into a conceptual proposal. A publicBoundaryOwner tiebreak was tried as a replacement, measured as decorative, and removed rather than kept. Fewer selections is the intended outcome where the old result was not supported by generic evidence. Independence gate A versioned manifest and a scanner that parses production with the TypeScript compiler and inspects string literals, template spans, regex literals, identifiers and comments, normalizing both to whole tokens and to the case-flattened form. The second form is load-bearing: most of the removed demotion table was written in it. The manifest imports the pinned targets' distinctive symbols from the frozen contract so it tracks the contract instead of drifting, and it refuses malformed, duplicate, wildcard, unused and expired entries. Two candidate rules were dropped rather than excepted, because the rules were wrong: statusLabel fired on Madar's own graphFreshnessStatusLabel, and RouterOutputs is framework-generic. Approved production exceptions: zero. The scanner does not claim to detect semantic overfitting, and says so. That class is owned by behavioural tests, and those tests are shown to own it: injecting a task-phrase score adjustment, or a repository-path boost, makes the substitution control fail on its own assertion. Controls - 9 behavioural controls, including a one-for-one substitution in which every identifier AND every question word is replaced and the ranking must come out identical. - 12 literal falsifiability controls and 4 semantic ones, each with a premise check, digest-verified byte restoration, and a requirement that failures be the intended assertion rather than any non-zero exit. Frozen qualification truth is unchanged; qualify:validate passes with and without --verify-corpus.

…sions
Bounded correction for HOLD-PR660B (thread 01a0561b). Six findings, all
accepted.
Spec — qualification-shaped behaviour that remained in production
The first pass removed the SYMBOL NAMES from the report-generation
compaction table but kept the table and broadened its regex to generic
architecture words. That is laundering, not decontamination, and it is
the exact shape the contract forbids. Removed outright instead:
- the report-generation prompt classifier and the detailed-phase
classifier built on it, with every consumer;
- the 80/40/20/5/-100 compaction priority table and both compaction
branches it fed;
- the answer-contract phase shaping (planner / research / assembly /
scoring / report-builder elements) fitted to that one task;
- the phase-taxonomy enablement and expected-phase list gated on the
same classifier;
- the noise filter that dropped candidates by matching that classifier
and a list of symbol names from a third repository.
Kept, with the reason measured rather than argued: the conceptual
slice-preservation mode. Removing it entirely, as the review suggested,
regressed generic cross-layer retrieval to one selected node with ten
obligations uncovered. Its condition is a property of the query plan --
no explicit anchors and at least four obligations -- and carries no
question wording or repository knowledge. What was contaminated was the
filter inside it, and that filter is gone.
Standards — the controls did not close the boundary they advertised
The reviewer evaded the scanner four ways. All four now fail closed, and
each has a permanent control:
- the raw-text pre-filter read files BEFORE decoding, so an escaped name
skipped the AST walk entirely and the scan reported clean. Removed;
every production file is parsed.
- regex source is decoded for \xHH, \uHHHH and \u{...} before matching.
- statically foldable concatenations and template expressions are folded,
so 'status' + 'Page' and `status${''}Page` match as the name they are.
- controls F12-F16 cover each encoding, and the folding boundary is
stated rather than implied: a name assembled at runtime is out of
reach of any static scanner, and this one does not pretend otherwise.
Manifest validation gained two refusals it was missing: an impossible
calendar date (2099-13-45 matched the shape but is not a date) and two
exemptions covering the same rule and file. Controls F17 and F18.
The semantic harness only ever mutated the fallback planner, and its
owning control watched boosts -- so a forced selection applied after
ranking was invisible to it. Added control D2, which compares final
end-to-end selections for the substituted repository, and controls
H4/H5, which inject a forced selection and a slice bypass into the
retrieval path itself and require D2 to fail on its own assertion.
CI
Both Windows lanes failed on the new step: `spawnSync('npx', ...)`
returns status null on Windows, where npx is a .cmd shim, so H0 read as
"the owning control is already failing". vitest is now resolved from its
own package manifest and run with the current node binary, and a spawn
that does not complete is reported as a spawn failure instead of being
counted as a caught defect.
25 independence controls pass. 188 affected tests pass. Frozen
qualification truth is still unchanged.

|---|---|

src/runtime/retrieval-gate.ts:244 |
reportGenerationShaped, the same phase vocabulary as runtime intent |
Completing the removal touches 6 production files against a hard maximum of 4. That is the HUMAN_GATE-660B-SCOPE condition in §4, reached on evidence rather than by estimate.
The slice-v1 bypass is contested on a point I cannot settle alone. The reviewer's counter is that query-plan decomposition is not typed repository evidence, and that my motivating regression comes from a qualification-shaped fixture — so the fixture cannot license the bypass. That is a fair argument. Deciding whether that cross-layer fixture represents generic behaviour or benchmark-shaped behaviour is a maintainer judgement.
Two controls are weaker than I claimed. The semantic harness filters on 'D. ', which does not establish D2 as green, and D2 never requests slice-v1, so H5 cannot prove slice-bypass detection; H4 only reorders candidates rather than forcing otherwise-unselected membership.
One scanner gap remains, verified empirically: /\163tatusPage/ executes as statusPage and the scanner reports 0 violations. Legacy octal escapes are not decoded.
Found by CI, not by the reviewer
Protected CI at bd4f1f59: 0 of 6 lanes green (it was 4 of 6 at f6c72869).
- A performance defect I introduced. Removing the raw pre-filter made the scan parse all 201 production files for every rule; the vitest control timed out at 15000 ms on every lane. Not a violation — a timeout.
- Three further test files lock the removed behaviour:
retrieve-production-correctness.test.ts(4 tests),spi-nest-di-runtime-calls-realistic.test.ts,pack-quality-fixtures.test.ts— referencing a third repository's symbols (IdeasController.listIdeas,.getStatusMessage(),ReportRepository.save). Each needs a §11 disposition.
The earlier Windows failure was also mine and is fixed: spawnSync('npx', …) returns status null on Windows, so the semantic harness read "the owning control is already failing".
What stands
- Production: 3 files, −565 net lines. Frozen qualification truth unchanged (
git diff 25ae7391 -- docs/is empty). - Literal inventory 45 → 0; 25 independence controls pass locally; 188 affected tests pass locally.
- The reviewer confirmed as sound: dropping the
statusLabelandRouterOutputsrules, removing the decorativepublicBoundaryOwnertiebreak, and the date / duplicate-scope / decoding / folding / byte-restoration work.
This PR is not mergeable as it stands and is not being merged. #660 remains open. #661 not started.
…val (#660-B1) Maintainer recut MAINTAINER-GO-660B1-BOUNDED-RECUT. This PR is now #660-B1: the explicit qualification contamination and the three-file retrieval and claim class. The remaining report-generation semantic class in prompt-pack.ts, retrieval-gate.ts and slicing.ts is Slice C and is untouched here. Scanner: one pass, not files x rules The scan renormalized every site for every rule, so its cost scaled with the rule count -- measured at 8729 ms for 36 rules and 4411 ms for 18 -- which is what timed the protected control out at 15 s. Sources are now read, decoded, parsed and normalized ONCE into an index, rule needles are normalized once, and matching is a substring test: 8729 ms -> 751 ms, with 201 files and exactly 201 parse calls. Four standing assertions keep it honest: parse count equals the unique production file count, a repeated file in the list does not become a second parse, every production file appears in the index, and halving the rules changes neither the parse count nor the site count. Results are also asserted stable under rule-order permutation. No raw-text pre-filter was restored: a pre-filter reads bytes before decoding, which is exactly how an escaped name skipped the AST walk before. Legacy octal escapes /\163tatusPage/ executes as /statusPage/ and scanned clean. The static decoder now resolves legacy octal escapes, and resolves the backreference ambiguity in the safe direction: only escapes decoding to printable ASCII are treated as octal, so \1..\9 stay backreferences and nothing is fabricated. Both spellings are kept in the diagnostic. No eval, no execution of production source. Controls F19 and F20; the unit control asserts both directions, so a decoder that stopped working cannot pass. Controls that were vacuous The semantic harness baselined with the filter 'D. ', which vitest never matches against 'D2. ' -- so the D2 baseline it claimed was never established. D and D2 now run as separate filters before injection, after every restoration, and at completion. D2 now requests slice-v1, records a measured baseline (selected ids, final membership, obligation totals, strategy) and asserts MEMBERSHIP rather than order. H4 and H5 change genuine membership and are required to prove it: the harness reads D2's own measurement and rejects the control when the selected set did not move. That check caught two earlier versions of H4 that only reordered candidates already selected, and one H5 filtering upstream of where membership is decided. Slice-v1: removed on independent evidence The bypass was kept in the previous round on a structural reading of its trigger. That is now settled by measurement rather than argument. Instrumenting the trigger across the retrieval, conceptual-fallback, pack-quality and production-correctness suites recorded eight firings on exactly three questions -- two openstatus-shaped, one report-generation -- and none on any independent fixture. Every pre-existing non-qualification pack-quality fixture is an implement task and never reaches the conceptual path at all. A mode only the benchmark reaches is benchmark tuning, so it is gone and a requested slice is always applied. Measured consequence, recorded not buried: a cross-service question with no explicit anchor is now sliced to a local slice. Five tests asserting the wider selection were dispositioned rather than re-snapshotted. Test disposition - Two tests asserting a task-gated expected-phase vocabulary (planner, external_research_or_api, report_builder, scoring, quality_gate) removed: production only ever enabled those phases when a prompt classifier recognised one benchmark task. - Two phase-coverage assertions narrowed to the phases still derived structurally from execution steps. - One negative assertion removed with its test retitled: it excluded .getStatusMessage() and .generateTitle() through a denylist of fourteen symbol names from one repository, not through any structural property. - Three tests depending on the removed slice bypass removed, each with the measurement recorded in place. 27 independence controls pass (21 literal, 6 semantic). 227 affected tests pass. Production remains exactly three files. Frozen qualification truth is unchanged.

Bounded correction for HOLD-PR660B1 (thread 01a05697). Both findings
accepted, plus two CI defects of my own found on the previous head.
Static evasions the reviewer demonstrated
/statusP{1}age/i contains no forbidden substring and matches the forbidden
name, so normalizing regex SOURCE can never settle the question. A regex is
a matcher, and the only faithful test is to ask the pattern. Regex sites are
now compiled with `new RegExp` -- which evaluates no production code -- and
tested against the rule value, bounded by source length and quantifier
count, with un-compilable patterns left to the text match rather than
guessed at.
Asking the pattern naively is far too eager, and the numbers are worth
recording because each step was a real defect:
no guard 1662 violations on a clean tree
+ fixed decoys 126 (length-keyed matchers slip through)
+ shape-mate decoys 118 (word-list matchers slip through)
+ symbol-class rules only 96 (fragment matches slip through)
+ whole-value coverage 40 (prefix-class matchers slip through)
+ swept head/tail decoys 0
So a regex is reported only when it matches the WHOLE value and matches
none of its shape-mates, tail-mates or head-mates -- that is, when it
recognises that specific name rather than a length, a shape, a word or a
class of names. Path-class rules stay with the text forms: a path value is
full of ordinary words, so "does this pattern match it" is not a well posed
question, and a regex hiding a path still trips the symbol rule for the
distinctive name inside it.
`'status'.concat('Page')` and `['status','Page'].join('')` now fold too.
Controls F21, F22, F23.
A control that proved nothing
B2 was titled "recovers a framework-declared route handler after every name
is changed" but supplied no framework role and asserted only a negative, so
deleting the claim builder outright left it green. It now supplies an
extractor-declared role unrelated to any qualification target and asserts
the exact claim text; the negative is kept as its own test, B2b. Verified
load-bearing by deleting the builder and watching B2 fail, then restoring
the file byte-identically.
CI defects on the previous head
Windows: every literal control passed, but H1/H2/H4/H5 failed with
"injection target not found". Only docs/qualification/** and *.madar are
pinned to LF, so src/** arrives with CRLF and a multi-line LF anchor
matches nothing. Injection anchors are now converted to the file's own line
ending before matching, so the controls test behaviour rather than checkout
settings.
Coverage lane: two scanner tests exceeded the 15s timeout under coverage
instrumentation because each rebuilt the index. The suite now builds one
index and shares it, which is what the one-pass design is for -- 1.67s of
test time. The timeout was not raised.
30 independence controls pass (24 literal, 6 semantic). 228 affected tests
pass. Production remains exactly three files; the Slice-C files and frozen
qualification truth are untouched.

type defect |
The blocker is the scanner's static-analysis completeness, not the decontamination. The reviewer explicitly confirmed as sound: B2/B2b, CRLF injection handling, shared-index reuse, parse-once behaviour, the three-file production scope, Slice-C isolation, and frozen truth unchanged.
The reviewer's own minimal correction begins "redesign regex classification to fail closed when bounded analysis is skipped". That is the recut's stop condition "the scanner requires another architecture", which is why this returns rather than continuing.
The design question for the maintainer
Evaluating arbitrary regex and expression obfuscation is an adversarial static-analysis problem with no clean fixed point — each round closes specific encodings and the next finds more. Three coherent resolutions:
- Fail closed on anything the bounded analysis cannot decide. Correct in principle, but it will flag legitimate complex regexes already in
src/and require exceptions for legitimate code. - Drop pattern evaluation and let the manifest own only decoded-literal contamination, with the obfuscation class owned by the behavioural controls — which is what the scanner's own report already says about semantic overfitting.
- Authorize one more bounded round on the scanner alone.
What stands
- Production: exactly 3 files. The Slice-C files are untouched (
git diff 25ae7391 -- <them>is empty). - 30 independence controls pass (24 literal, 6 semantic); 228 affected tests pass.
- Literal B1 inventory 45 → 0; approved production exceptions 0.
- Frozen qualification truth unchanged.
Not merged, and not mergeable as it stands. #660 remains open pending Slice C. #661 not started.
MAINTAINER-GO-660B1-DECODED-LITERAL-SCANNER. The scanner is a bounded
regression detector for explicit qualification knowledge. It detects
literals, decoded escapes, normalized encodings, identifiers and path
fragments, statically foldable string constructions, and literal text
inside regex source. It does not decide the semantic language of a regular
expression, and it no longer tries.
Removed: regex semantic evaluation
Gone entirely -- regexMatchesValue, the shape/tail/head specificity decoys,
the source-length and quantifier bounds that existed only to make
compilation safe, and the fail-open behaviour attached to those bounds. No
partial regex interpreter replaces it: no RegExp construction over
production source, no eval, no execution of source expressions, no
backtracking analyser, no third-party parser. The TypeScript parser still
identifies a regex literal and extracts its source text, which is all that
was ever needed.
The record for why: asking a compiled pattern whether it COULD match a
forbidden value produced 1662 false positives on a clean tree, took five
rounds of narrowing to reach zero, and still failed OPEN whenever its own
bounds were exceeded. A guard that fails open is worse than one with a
stated edge.
Retained: regex source as decoded text
A regex literal remains a knowledge-bearing textual site carrying raw
spelling, decoded spelling, file, line, site kind and both normalization
forms. All five required forms are caught as text:
/statusPage/ /\x73tatusPage/ /statusPage/
/\u{73}tatusPage/ /\163tatusPage/
Uniform rule classes
Every rule class is tested against every decoded site kind. The earlier
symbol-only restriction on regex sites is gone and does not survive as a
textual exclusion: a path rule now matches a regex source, escaped or not,
and results are asserted independent of manifest rule order.
Static folding for spreads and holes
The bounded folder handles static spread operands and array holes, which
evaluate at runtime to exactly the plain spelling:
'status'.concat(...['Page'])
['sta', ...['tus'], 'Page'].join('')
['status',, 'Page'].join('') // elided element joins as ''
Controls F24, F25, F26. F21 is gone with the capability it tested.
The edge, asserted rather than implied
A named test asserts that `/statusP{1}age/` and `/^(?=statusP{1}age$)/` are
NOT detected: they match at runtime, no decoded textual run of their source
spells the value, and that is outside this contract. Some semantically
clever patterns are caught anyway when their source happens to contain the
run -- a coincidence of spelling, not a capability, and not claimed as one.
The test exists so the limitation is recorded rather than rediscovered, and
so a change that quietly reintroduces pattern evaluation has to confront it.
That class, and semantic overfitting generally, stays with the behavioural
independence tests, the unrelated-name and renamed-implementation controls,
independent holdout evaluation in #661, and code review.
`matchForms` is `tokens | squashed` again, which is now the truth.
32 independence controls pass (26 literal, 6 semantic). 232 affected tests

qualification truth are untouched.

A bare `ArrayLiteralExpression` was folded as the concatenation of its
elements. That is not what JavaScript does: `['status', 'Page']` is an
array, whose string coercion is `status,Page`, and it was being reported as
the forbidden name `statusPage`. The same branch made an array-receiver
`.concat()` look like string concatenation -- `['status'].concat('Page')`
returns the ARRAY `['status','Page']`.
Both were false positives. A guard that invents matches is as untrustworthy
as one that misses them.
Corrected
`staticValue` no longer gives a bare array a string value, and array
literals are no longer recorded as folded sites. Array elements are still
processed, but only inside the operations whose semantics are modelled: a
`.join(separator)` receiver, a static spread operand, and `staticList` as
their shared representation.
`.concat` folds only for a string receiver, decided by a narrow shape test
that returns false for anything it cannot recognise as a string form. It is
a shape test, not type inference, and the evaluator is not broadened.
'status' + 'Page' folds
`status${''}Page` folds
'status'.concat('Page') folds
'status'.concat(...['Page']) folds
['status', 'Page'].join('') folds
['sta', ...['tus'], 'Page'].join('') folds
['status', , 'Page'].join('') folds (hole joins as '')
['status', 'Page'] DOES NOT fold
['status'].concat('Page') DOES NOT fold
Declining to fold an array does not hide its members: a forbidden literal
inside an unfolded array is still caught as a string site, which is the
shape a preferred-file list actually takes.
Verified load-bearing rather than assumed: reintroducing the bare-array
branch makes the new control fail with the exact message, and the file was
restored byte-identically afterwards.
Capability contract
The scanner's boundary is now declared as data in SCANNER_CAPABILITIES and
asserted by a test whose subject is the contract, not a bug: literal and
static detection enabled; regex semantic evaluation disabled;
runtime-constructed-value proof and semantic-overfitting proof not claimed.
The same test pins that /statusPage/, /\x73tatusPage/ and /\163tatusPage/
are detected after source decoding, while /statusP{1}age/ and
/^(?=statusP{1}age$)/ are not interpreted as equivalent. It asserts those
two patterns individually rather than claiming every complex pattern is
absent -- a pattern may coincidentally contain the text directly, and would
then be detected, correctly.
Widening the contract now requires deliberately changing the declaration
and this test.
32 independence controls pass (26 literal, 6 semantic). 233 affected tests
pass. Scripts and tests only: no permanent production file is altered, the
production diff remains the same three files, and frozen qualification
truth is untouched.
FINAL review verdict —
|
| Runtime | "statusundefinedPage" |
| Scanner | folds to "statusPage", reports openstatus/symbol-status-page |
A false positive — the scanner claims a forbidden literal that the code does not contain. This is the same class as the bare-array defect corrected earlier in this session, and it falls squarely inside §14's list ("a declared static fold is semantically wrong" / "an unsupported coercion creates a false folded value"). It is not a demand for regex semantic evaluation, so it is not an excluded reviewer demand.
Root cause
staticList maps an array hole to the empty string unconditionally. That is correct for one consumer and wrong for the other:
[, "Page"].join("") -> "Page" hole renders as '' (correct)
"status".concat(...[, "Page"]) -> "statusundefinedPage" hole spreads as undefined
Array.prototype.join renders holes and undefined as ''; a hole spread into .concat becomes undefined and coerces to the text "undefined". The hole's meaning is context-dependent, and the shared staticList does not distinguish its two consumers.
The defect is in scripts/. No permanent production file is affected.

MAINTAINER-GO-660B1-ARRAY-HOLE-CONTEXT-CORRECTION. The FINAL reviewer
correctly reproduced an in-contract false positive:
'status'.concat(...[, 'Page']) -> 'statusundefinedPage' (runtime)
-> 'statusPage' (scanner)
The scanner claimed a forbidden literal the code does not contain.
Root cause
`staticList` collapsed an array hole to the empty string at collection time.
That is right for one consumer and wrong for the other, because a hole's
rendering is a property of who reads it:
['status', , 'Page'].join('') -> 'statusPage' hole renders ''
'status'.concat(...[, 'Page']) -> 'statusundefinedPage' hole is undefined
`Array.prototype.join` renders holes and undefined as the empty string; a
hole SPREAD into `String.prototype.concat` materialises a real `undefined`,
which stringifies as the text 'undefined'. One helper, two consumers, and
the collapse discarded the distinction before either could apply it.
Correction
A hole is now carried as a distinct `HOLE` sentinel and rendered by the
operation that consumes it -- `renderForJoin` gives '', `renderForConcat`
gives 'undefined'. The evaluator is not broadened; nothing new folds. The
fold is now CORRECT rather than merely suppressed: the expression folds to
`'statusundefinedPage'`, which simply does not contain the forbidden name.
Every modelled construction is checked against the value JavaScript really
produces, using real thunks rather than eval:
'status' + 'Page' 'statusPage'
'status'.concat('Page') 'statusPage'
'status'.concat(...['Page']) 'statusPage'
['status', 'Page'].join('') 'statusPage'
['sta', ...['tus'], 'Page'].join('') 'statusPage'
['status', , 'Page'].join('') 'statusPage'
['status', ...[, 'Page']].join('') 'statusPage'
[, 'Page'].join('') 'Page'
'status'.concat(...[, 'Page']) 'statusundefinedPage'
['status', 'Page'] array, no fold
['status'].concat('Page') array, no fold
The reviewer's exact reproduction is kept as a standing control, and both
controls were proved load-bearing: reintroducing the collapse fails them
with "folded to something JavaScript does not produce" and "a construction
that never spells the name was reported", and the file was restored
byte-identically.
32 independence controls pass. 234 affected tests pass. Scanner scripts and
tests only: no permanent production file is altered, the production diff

The reviewer's exact reproduction is kept as a standing control. Both controls were proved load-bearing: reintroducing the collapse fails them with folded to something JavaScript does not produce and a construction that never spells the name was reported, and the file was restored byte-identically.

Not merged — the merge decision is the maintainer's, because B1 deliberately changes core retrieval, selection and claim behaviour. #660 remains open pending Slice C; #661 not started.

Implements #660, Slice B1.
Slice A merged as
25ae7391(PR #730) and was post-merge verified. Under the maintainer recutMAINTAINER-GO-660B1-BOUNDED-RECUT, #660 is delivered in three slices and this PR is B1 only. #660 is not complete when this merges.Scope of B1
The explicit/literal qualification contamination and the retrieval/claim class in exactly three production files:
src/runtime/context-pack.tssrc/runtime/retrieve.tssrc/runtime/retrieve/conceptual-fallback.tsThe task-phrase rules in those three files — the
public+pageobligation rules, the forced HTTP-boundary reservation, the cross-runtime forced selection, and the conceptual slice bypass — are removed or dispositioned.What remains, and is NOT in this PR
The report-generation semantic class is still present in three other production files, which B1 does not touch:
src/infrastructure/prompt-pack.ts—promptWantsReportGenerationCore, and the emitted instruction "Follow planner, research, assembly, scoring, rendering, and persistence evidence"src/runtime/retrieve/slicing.ts— a duplicate of the same classifier, and a name-driven anchor score tablesrc/runtime/retrieval-gate.ts— thereportGenerationShapedvariantThose are Slice C, one future PR, maximum three permanent production files. Slice C is not started. Affected tests already identified for it:
retrieve-production-correctness.test.ts,spi-nest-di-runtime-calls-realistic.test.ts,pack-quality-fixtures.test.ts.Scanner: one pass, not files × rules
The scan renormalized every site for every rule, so cost scaled with the rule count — 8729 ms at 36 rules, 4411 ms at 18 — which is what timed the protected control out at 15 s. Sources are now read, decoded, parsed and normalized once into an index; rule needles are normalized once; matching is a substring test.
8729 ms → 751 ms. 201 files, exactly 201 parse calls.
Four standing assertions keep that honest: parse count equals the unique production file count; a repeated file does not become a second parse; every production file appears in the index; halving the rules changes neither the parse count nor the site count. Output is also asserted stable under rule-order permutation.
No raw-text pre-filter was restored. A pre-filter reads bytes before decoding, which is precisely how an escaped name skipped the AST walk in the first place.
Legacy octal escapes
/\163tatusPage/executes as/statusPage/and scanned clean. The static decoder now resolves legacy octal escapes and resolves the backreference ambiguity in the safe direction: only escapes decoding to printable ASCII are treated as octal, so\1–\9stay backreferences and nothing is fabricated. Both raw and decoded spellings are kept in the diagnostic. Noeval, no execution of production source. Controls F19/F20, plus a unit control asserting both directions.Controls that were vacuous, and now are not
The semantic harness baselined with the filter
'D. ', which vitest never matches against'D2. '— so the D2 baseline it claimed was never established. D and D2 now run as separate filters before injection, after every restoration, and at completion.D2 requests
slice-v1, records a measured baseline (selected ids, final membership, obligation totals, strategy) and asserts membership, not order. H4 and H5 change genuine membership and must prove it: the harness reads D2's own measurement and rejects the control if the selected set did not move. That check caught two earlier versions of H4 that only reordered already-selected candidates, and an H5 filtering upstream of where membership is decided.Slice-v1: removed, on independent evidence
The bypass was retained in the previous round on a structural reading of its trigger. That is now settled by measurement. Instrumenting the trigger across the retrieval, conceptual-fallback, pack-quality and production-correctness suites recorded eight firings on exactly three questions — two openstatus-shaped, one report-generation — and none on any independent fixture. Every pre-existing non-qualification pack-quality fixture is an
implementtask and never reaches the conceptual path at all.A mode only the benchmark reaches is benchmark tuning, whatever its condition looks like. It is removed and a requested slice is always applied.
Measured consequence, recorded rather than buried: a cross-service question with no explicit anchor is now sliced to a local slice. Five tests asserting the wider selection were dispositioned, not re-snapshotted.

A bounded decoded-literal regression detector, declared as data in
SCANNER_CAPABILITIESand pinned by a contract test rather than by prose:It reads regex source as text and decodes escapes —
/statusPage/,/\x73tatusPage/,/\u0073tatusPage/,/\u{73}tatusPage/,/\163tatusPage/are all detected. It does not interpret what a pattern can match:/statusP{1}age/and/^(?=statusP{1}age$)/matchstatusPageat runtime and are deliberately not classified. That is asserted by the contract test, not left to prose, so widening it requires changing the declaration on purpose.Regex semantic evaluation was removed rather than narrowed. Compiling patterns to ask whether they could match produced 1662 false positives on a clean tree, took five rounds to reach zero, and still failed open when its own bounds were exceeded.
Semantic overfitting stays with the behavioural independence tests, the unrelated-name and renamed-implementation controls, independent holdout evaluation in #661, and code review.
Static folding, corrected
A review found the folder treating a bare array as string concatenation —
['status', 'Page']is an array (coerced:"status,Page"), notstatusPage. The same branch made['status'].concat('Page')— which returns an array — look like string concatenation. Both were false positives. Bare arrays no longer fold, and.concatfolds only for a string receiver.Array elements are still processed in exactly the operations whose semantics are modelled:
'status' + 'Page'`status${''}Page`'status'.concat('Page')'status'.concat(...['Page'])['status', 'Page'].join('')['sta', ...['tus'], 'Page'].join('')['status', , 'Page'].join('')''['status', 'Page']['status'].concat('Page')Declining to fold an array does not hide its members: a forbidden literal inside an unfolded array is still caught as a
stringsite, which is the shape a preferred-file list takes.Verification
--verify-corpusFinal correction — an array hole is rendered by its consumer
The bounded folder collapsed an array hole before knowing which operation consumed it. That discarded a distinction the language makes:
Array.prototype.joinrenders a hole as the empty string.String.prototype.concatmaterialisesundefined, which becomes the text"undefined".The corrected bounded fold is therefore:
so it does not produce a false
statusPageviolation. Both join forms still fold as they should:No new expression class was added to the evaluator. All modelled constructions are cross-checked against direct JavaScript thunks, so a fold that disagrees with the language fails the suite in either direction.

01a0576b-eb72-7750-86f3-2fc01ab01ac1, verifying its own reproduced finding. It was not a fresh FINAL thread.What this does not establish
This slice does not show that Madar generalizes, and does not compare it to native exploration. Removing contamination is a precondition for a trustworthy measurement, not the measurement. Tier 1 evaluation is owned by #661 and is not started.
The scanner owns literal and normalized contamination only and says so in its own report; it does not claim to detect all semantic overfitting, and the repository as a whole is not decontaminated while the Slice-C class stands.
The stale E3 sentence in
docs/qualification/evidence-categories.mdremains a known frozen-contract statement; the deliberate contract-version update is deferred to #661.Related parent: #660 remains open pending Slice C.
