Add decompose_audit(audit_path) to teaching/math_contemplation.py.
Groups audit_brief_11.json refusal rows by
(refusal_reason, missing_operator), emits one
MathReaderRefusalShapeProposal per group of >=2 rows, each carrying a
4-step ReasoningTrace (observation -> grouping -> hypothesis ->
conclusion).
Determinism:
- Group iteration sorted by (refusal_reason, missing_operator).
- Evidence per group sorted by case_id.
- Output tuple sorted by proposal_id.
- 10x rerun -> byte-identical proposals + trace_ids.
Pure read-only: audit file is not mutated, no proposals written to
disk, no chat/field/generate/algebra imports.
Tests (tests/test_adr_0172_w2_decomposer.py): real-audit emission,
determinism (10x), evidence floor, change-kind dispatch over all four
heuristic branches, four-step trace, case_id sort, proposal_id sort,
empty input -> empty tuple, unmapped operator skip, missing file ->
FileNotFoundError, no-mutation contract.
Added to core test --suite teaching.
New module `teaching/math_contemplation_proposal.py` defines the
`MathReaderRefusalShapeProposal` dataclass — the math-domain analog of
`TeachingChainProposal` for the Tier-1 contemplation corridor.
- `build_proposal` enforces all seven invariants: math domain, ShapeCategory
enum membership, ≥2 evidence pointers, valid ChangeKind Literal, JSON-
serializable payload, ≥40-char wrong_zero_assertion, and non-None
reasoning_trace with a non-empty trace_id.
- `canonical_bytes` / `compute_proposal_id` produce stable sha256-based IDs;
evidence reduced to evidence_hash, trace to trace_id for stability.
- `ReasoningTrace` imported under TYPE_CHECKING only (W0/A1 not yet merged);
duck-typed at runtime via trace_id attribute.
- 16 tests cover all eight brief obligations plus freeze and sensitivity checks.
- `core test --suite teaching -q` green (17 passed).
Schema-only module defining ReasoningStep / ReasoningTrace with
byte-identical canonical serialization and sha256 trace_id derivation.
Replay-equivalence is enforced by:
- sorted-key JSON, no whitespace, ensure_ascii=False, allow_nan=False
- recursive rejection of float values in payloads (replay hazard)
- step_index monotonicity from 0
- empty trace rejected
- Literal-checked step_kind across all eight Tier 1+2 kinds
No runtime hook. No import from chat/field/generate/algebra.
Downstream (W1 ShapeProposal, W2 decomposer) consume this schema.
Tests: 12 new, full teaching suite green (17 passed).
Second implementation PR of the ADR-0170 wave. Extends the DCS injector
to emit ``CandidateOperation(kind='add')`` for acquisition verbs
alongside the existing ``CandidateInitial`` emission for possession
verbs. Proves the W1 type-widening with real emission of both union
members.
## What changes
### `generate/recognizer_match.py`
- New `_ACQUISITION_VERBS` frozenset (12 verbs: collect/get/receive/buy
inflections). Each member is a subset of `ADD_VERBS` so the downstream
CandidateOperation post-init whitelist accepts the matched_verb token.
- Extractor now accepts either possession OR acquisition verbs and
records `anchor_kind` (`"possession"` | `"acquisition"`) plus
`verb_token` in the parsed anchor schema.
### `generate/recognizer_anchor_inject.py`
- `inject_discrete_count_statement` dispatches on `anchor_kind`:
- `"possession"` → `CandidateInitial` (existing behavior unchanged)
- `"acquisition"` → `CandidateOperation(add)` (new)
- New helper `_build_operation_from_discrete_count_acquisition`
constructs the operation. Operand uses `_resolve_count_value`;
matched_verb uses `_locate_token` for round-trip ground check.
- Return type uses `InjectorEmission` from W1.
### Tests
- `tests/test_adr_0170_w2_dcs_acquisition_verbs.py` (new) — 22 tests:
- Verb-set membership pins
- Acquisition ⊂ ADD_VERBS sanity check
- Possession + Acquisition disjoint
- Extractor records anchor_kind correctly
- Injector emits CandidateOperation for acquisition verbs
- Possession path still emits CandidateInitial unchanged
- Deliberate exclusions (gained / donated / saved) still refuse
- Case 0050 hazard pinned (does/contemplates not in either set)
- Determinism + roundtrip_admissible passes
- Updated `tests/test_adr_0163_d2_discrete_count_injection.py` to
reflect new anchor schema fields (anchor_kind, verb_token).
- Updated `tests/test_adr_0170_w1_injector_type_widening.py` —
the DCS injector now legitimately returns
`tuple[InjectorEmission, ...]` (not narrower).
## Deliberate exclusions
These verbs are NOT in `_ACQUISITION_VERBS` and the extractor refuses
them — preserving wrong=0:
- `gained / gains / gain` — delta-of-attribute (weight, age), not
acquisition. Admitting as add-operation would risk wrong>0 on
questions that ask total state.
- `donated / donates / donate` — SUBTRACT semantics (actor gives away).
- `saved / saves / save` — ambiguous (time vs money vs effort).
Widening this set is operator-reviewable per `feedback-wrong-zero-
hazard-case-0050` discipline.
## ADR-0131.G.1 branch-disagreement discipline preserved
The regex parser already emits `CandidateOperation(add)` for
acquisition verbs via `ADD_VERBS` for single-word units. The new DCS
injector path emits the same kind of operation for multi-word units
(where the regex parser fails). Collapsed-tie when both paths emit
identical operations on overlapping shapes; no disagreement.
## Test plan
- tests/test_adr_0170_w2_dcs_acquisition_verbs.py: 22 passed (new)
- tests/test_adr_0163_d2_discrete_count_injection.py: ~30 passed
(existing tests updated for new schema fields)
- tests/test_adr_0170_w1_injector_type_widening.py: 6 passed
- tests/test_recognizer_skip_wrong_zero.py + brief_11b + brief_11 +
candidate_graph_wiring + candidate_domain_partition: passed
- evals/gsm8k_math/train_sample/v1: counts=correct=3 refused=47 wrong=0
unchanged (case 0023 still has S2/S3 downstream blockers; W2's value
is infrastructure, not direct lift)
## Hard invariants
- `wrong == 0` preserved (case 0050 hazard pin + deliberate verb
exclusions + roundtrip_admissible gate)
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
- ADR-0131.G.1 branch-disagreement discipline preserved (acquisition →
operation, not initial)
- Five-layer wrong=0 safety net (ADR-0163.D.2) intact and extended
## W3 NOT in this PR — honest skip
Initial plan was to bundle W2 + W3 (A1 currency_amount injector).
Inspection of the 4 actual `currency_amount` GSM8K refusals showed
none match A1's narrow form (`<ProperNoun> earns|charges $<amount>`):
| Case | Statement | Reason narrow form doesn't fit |
|---|---|---|
| 0019 | "this requires 3 vet appointments, which cost $400 each" | anaphoric subject + multi-quantity |
| 0026 | "Aaron and his brother Carson each saved up $40" | multi-subject + "each" |
| 0028 | "It cost $100,000 to open initially" | pronoun subject |
| 0043 | "Her mother gave her an additional $4, and her father twice as much" | multi-clause + comparative + transfer |
Shipping W3 as-designed would have re-introduced the dead-code pattern
#373 just cleaned up. Skipped honestly; ADR-0172 Tier 1's decomposer
(the next wave) will surface category-shape mismatches like this
programmatically.
The G.2 test \`_comparative_clause_refusal_count\` reads \`report.json\`
and counts refusals whose reason quotes a statement clause containing
comparative anchors ("more/less than", "twice as many", etc.). After
#359's wrong=0 fix, the candidate-graph emits two refusal-reason
families that both quote a statement:
1. "no admissible candidate for statement: '...'" — parser-path
refusal (the comparative-parse-failure family this metric tracks).
2. "recognizer matched but produced no injection for statement:
'...'" — recognizer-path refusal; the quoted statement may
incidentally contain comparative anchors but the refusal cause is
the missing injector, NOT the comparative parse.
The pre-#359 counter only saw family (1) reasons; post-#359 it
over-counts whenever a recognizer-path refusal quotes a statement
containing comparative anchors. This was the test failure A2's PR
(#369) and the cleanup PR (#373) both surfaced.
## Fix
Filter the counter to exclude family (2) explicitly. Recognizer-path
refusals are tracked separately by the recognizer-wiring test suite;
they don't belong in the G.2 metric.
Result on current main:
- total statements with comparative anchors in refusal reasons: 2
- parser-path: 1 (case 0009, the legitimate G.2-tracked refusal)
- recognizer-path: 1 (filtered out — incidental anchor in #359-format reason)
- G.2 metric correctly reports 1 < baseline 2 → assertion passes
## Also: refresh report.json
The checked-in \`report.json\` was generated pre-#359 with the legacy
refusal-reason format. The runner now emits the new format on every
run; checking in the current output makes the baseline reproducible
and clears the CI friction that A2 originally flagged.
## Test plan
- tests/test_adr_0131_G2_comparatives.py: 25 passed (was 24 pass / 1 fail)
- tests/test_adr_0131_G4_multi_clause.py + G5_aggregate + S1_rate_events: 105 passed
- tests/test_brief_11b_audit_artifact + step2_lexicon + recognizer_skip + brief_11_audit + wiring + partition + adr_0163_d2: 89 passed
- Total: 219 passed
## Hard invariants
- No runtime change
- wrong=0 invariant preserved
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
First implementation PR of the ADR-0170 wave. Type-level widening only:
the recognizer-injector dispatch now returns
``tuple[InjectorEmission, ...]`` where
``InjectorEmission = CandidateInitial | CandidateOperation``.
The existing ``inject_discrete_count_statement`` continues to emit only
``CandidateInitial`` — the widening unlocks but does not exercise
operation emission. Subsequent W2-W5 PRs ship the per-injector emission
shapes:
- W2 — DCS-S1 acquisition verbs (CandidateOperation(add))
- W3 — A1 currency_amount (CandidateInitial reimplementation)
- W4 — A3 multiplicative_aggregation (CandidateInitial(product))
- W5 — A4 temporal_aggregation (deferred until apply_rate primitive)
## Changes
### `generate/recognizer_anchor_inject.py`
- New `InjectorEmission = Union[CandidateInitial, CandidateOperation]`
- `inject_from_match` return type widened to
`tuple[InjectorEmission, ...]`
- `__all__` exports `InjectorEmission`
- Documentation comment names ADR-0170 §"Implementation outline"
### `generate/math_candidate_graph.py` (admissibility dispatch)
The per-statement admission loop now dispatches admissibility on the
concrete candidate type:
if isinstance(c, CandidateInitial):
if _initial_admissible(c): admitted.append(c)
elif isinstance(c, CandidateOperation):
if roundtrip_admissible(c): admitted.append(c)
No new admission semantics — each type is gated by the predicate it was
already gated by elsewhere in the codebase. The dispatch unifies the
injector path with the parser path.
### `tests/test_adr_0170_w1_injector_type_widening.py` (new)
- Pin: `InjectorEmission` union members are exactly the two candidate types
- Pin: `inject_from_match` return type is widened
- Pin: `inject_discrete_count_statement` still emits CandidateInitial (W1
is type-level only)
- Hazard pin: case 0050 remains refused
- Hazard pin: unparseable-verb refusal path (#359) unchanged
- Anti-regression: canonical DCS narrow-form extraction still works
## Test plan
- tests/test_adr_0170_w1_injector_type_widening.py: 6 passed (new)
- tests/test_adr_0163_d2_discrete_count_injection.py: 21 passed
(existing D.2 v1 injector regression)
- tests/test_brief_11b_audit_artifact.py + step2_lexicon +
recognizer_skip_wrong_zero + brief_11_audit: 55 passed
- tests/test_candidate_graph_recognizer_wiring.py: 7 passed
- tests/test_candidate_domain_partition.py: 5 passed
- tests/test_adr_0131_G2_comparatives + G4 + G5 + S1_rate_events:
130 passed
- Total: 225 passed
- evals/gsm8k_math/train_sample/v1: counts=correct=3 refused=47 wrong=0
(unchanged; verified no behavioral regression)
## Hard invariants
- `wrong == 0` preserved (admissibility dispatch is type-aware but
semantically identical to the parser path's gating)
- ADR-0166: no new eval lanes
- No teaching-store / pack mutation
- Five-layer wrong=0 safety net (ADR-0163.D.2) intact
- Reader path unchanged
Three concrete cleanup items from the day's work, per the
cleanup-as-you-find memory principle.
## 1. Remove inject_rate_with_currency stub
PR #369 (A2 rate_with_currency) shipped a function that always returns
() with an extensive docstring documenting the Rate-not-in-SentenceChoice
schema gap. The function is dead at runtime — `_INJECTORS.get(category)`
returning None has the same downstream behavior as the function
returning (). The 16 tests pinned the empty-tuple return; the case-0050
hazard pin is duplicated in test_recognizer_skip_wrong_zero.py and
test_brief_11b_step2_lexicon.py.
The schema gap is now properly documented in ADR-0170 (PR #372). A
dispatch-table comment at the removal site retains the at-code pointer
to that ADR for anyone wiring a new injector.
Removed:
- `inject_rate_with_currency` function in generate/recognizer_anchor_inject.py
- Its `_INJECTORS` dispatch table entry
- Its `__all__` export
- tests/test_injector_rate_with_currency.py (371 lines, 16 tests)
## 2. Remove docs/handoff/GPT55-MOBILE-DISPATCH.md
Single-session travel-time scaffolding. The 5 tasks it named are
complete or superseded by ADR-0170's findings. Pure historical artifact.
## 3. Remove docs/handoff/WAVE-NEXT-INJECTORS.md
Superseded by docs/handoff/WAVE-NEXT-REVISED.md, which captures
everything load-bearing from the original brief in its A1–A4 findings
table. The "kept for history" justification didn't survive scrutiny:
the document was misframed (over-promised lift; misframed schema work
as injector work). Lessons captured in REVISED + ADR-0170.
Updated cross-references:
- WAVE-NEXT-REVISED.md: removed the "supersedes ... kept for history"
pointer; tightened cross-reference list
- ADR-0167-FOLLOWUPS.md §7: rewrote pointer to name ADR-0170 + REVISED
as the live plan rather than "the original is retained"
## Test plan
- 219 tests passed across G.2/G.4/G.5/S1/Brief 11/B1/B11A/wiring/partition/DCS-D.2
- evals/gsm8k_math/train_sample/v1/report.json untouched (regen
surfaces a separate stale-baseline test issue — out of cleanup scope)
- No runtime behavior change
## Net impact
- 5 files removed (~1200 lines)
- 1 file modified for explanatory comment (~30 lines)
- 2 doc files updated to remove dangling cross-references
- 0 behavioral change
The wrong=0 fix in #359 changed the candidate-graph's refusal-reason
format when a ratified recognizer matches but its v1 injector returns
():
- Pre-#359: silently drop the recognized statement and admit a partial
graph from the rest — a wrong>0 hazard analogous to case 0050.
- Post-#359: refuse explicitly with reason "recognizer matched but
produced no injection" naming the statement and recognizer category.
Three tests in `test_candidate_graph_recognizer_wiring.py` were written
against the pre-#359 silent-drop behavior:
1. `test_empty_registry_preserves_existing_refusal_reason` — asserted
the old "no admissible candidate" was the only valid format. Updated
to accept either the legacy format OR the new explicit-refusal
format.
2. `test_recognized_rate_statement_no_longer_triggers_per_statement_refusal`
— asserted that recognized statements should NOT cause a per-statement
refusal (encoding the silent-drop premise). Inverted to assert the
correct post-#359 behavior: recognized-but-uninjectable statements
refuse EXPLICITLY, and the statement IS named in the diagnostic.
Renamed to `_refuses_explicitly_post_wrong_zero_fix`.
3. `test_recognized_descriptive_statement_no_longer_triggers_per_statement_refusal`
— same inversion + rename.
Renames preserve the original sites for git-blame continuity while
making the post-#359 contract the documented behavior.
No runtime change. wrong=0 invariant preserved.
Test plan:
- tests/test_candidate_graph_recognizer_wiring.py: 7 passed (was 3 fail / 4 pass)
- tests/test_candidate_domain_partition.py: 5 passed (no cognition regression)
- tests/test_brief_11b_audit_artifact.py + step2_lexicon + recognizer_skip_wrong_zero + brief_11_audit: 55 passed
- Total: 62 passed
Wave-Next A2 brief outcome: the Rate type (ADR-0122) DOES structurally
model a per-unit rate, but it is not a member of the per-sentence
injector contract's SentenceChoice union (CandidateInitial |
CandidateOperation). The injector therefore returns () and documents
the schema gap inline plus in audit_brief_11.md.
Lift count: 0 (expected — the brief explicitly anticipates this
outcome when the schema decision is "no"). Documenting the gap is
the deliverable.
- generate/recognizer_anchor_inject.py: new inject_rate_with_currency
+ dispatch-table entry routing ShapeCategory.RATE_WITH_CURRENCY.
- tests/test_injector_rate_with_currency.py: 16 tests pinning schema
evidence, schema refusal, dispatch wiring, case 0050 hazard,
determinism, and wrong=0 invariant.
- evals/gsm8k_math/train_sample/v1/audit_brief_11.md: appended
Wave-Next A2 section documenting the schema decision, eval delta
(3/0/47 unchanged), case 0050 hazard verification, and the
CandidateRate follow-up sequencing.
Case 0050 hazard pin: sentence 0 ("Mark does a gig every other day
for 2 weeks.") carries no currency symbol — rate_with_currency
never matches it; case stays refused at sentence_index=0.
Adds 3 drain_token lemmas to en_core_math_v1 closing 2 of 3 remaining
lexicon_entry refusals from the prior wave:
- path (case 0049, new lemma)
- journey (case 0049 follow-on after path resolved)
- sees → alias of existing "see" lemma (case 0040)
The third remaining lexicon_entry refusal (case 0001, '+') is
deliberately NOT closed: '+' is an arithmetic operator literal, not a
lexical token. Adding it as drain_token would silently drop arithmetic
content from problems like "5 + 3 apples", a wrong=0 hazard. Documented
in the PR body and audit artifact.
Refusal taxonomy shift:
- unknown_word: 5 → 3 (-2)
- unresolved_pronoun: 3 → 4 (+1) — case 0049's pronoun barrier surfaced
- incomplete_operation: 20 → 21 (+1) — case 0049's quantity gap surfaced
Hard invariants:
- wrong == 0 (admitted=0, verified)
- case 0050 hazard pinned (refused at sentence_index=0)
- manifest checksum unchanged (per-category source file edit)
- no teaching-store mutation; no reader runtime change
## Summary
Two test failures on origin/main both trace to PR #315 (ADR-0163.D.2 —
discrete_count_statement recognizer + admissibility-intent chain). Earlier
runs treated them as "pre-existing unrelated" — they are not unrelated.
The first is a real wrong>0 hazard.
## Failure 1: silent admission via recognized-but-uninjectable statement
The ratified `discrete_count_statement` recognizer over-matches: ANY
sentence containing a number + noun resolves it, irrespective of the verb.
When `inject_from_match` returns `()` (the round-2 default for v1
categories without an injector), the old code path used `continue` to
silently drop the statement — and the solver then answered from whatever
initial state remained.
Reproduction:
parse_and_solve("Sam has 5 apples. Sam contemplates 3 apples. "
"How many apples does Sam have?")
→ is_admitted=True, answer=5.0 (silent admission of partial graph)
This is exactly the case-0050-class hazard wearing a different hat
(silently admitting an incomplete graph at the problem level).
ADR-0167 / Brief 11 §"correct-count greed" established the principle on
the reader path; this commit extends it to the recognizer path.
Fix: when a recognizer matches but produces no injection, REFUSE.
generate/math_candidate_graph.py:
- Replaced the skip-only `continue` with a CandidateGraphResult
refusal carrying the recognizer category in the reason.
tests/test_math_candidate_graph.py:
- test_unparseable_statement now accepts either the legacy
"no admissible candidate" reason or the new
"recognizer matched but produced no injection" reason.
Both legitimately refuse; what matters is is_admitted=False.
tests/test_recognizer_skip_wrong_zero.py (NEW):
- 5 regression tests pinning the wrong=0 invariant:
* 3 parametrized verbs unknown to both regex parser and reader
(contemplates / ponders / memorises) — must all refuse
* Nonsense token — must refuse
* Anti-regression: known initial + known operation still admits
## Failure 2: cognition audit drop-reason taxonomy
The audit test hardcoded `dropped.reason.startswith("superseded_by:")`
as the only valid drop-reason prefix. Commit da70919 (ADR-0163.D.2)
ratified an admissibility-intent chain that the audit categorizes with
reason `unsupported_intent:admissibility`, which fails this assertion.
Fix: tests/test_teaching_audit.py — expand the allowed-prefix set to
include `unsupported_intent:` with a written rationale. Future drop
classes extend the allowlist deliberately rather than silently
broadening the assertion to any non-empty reason.
## Surfaced regression: partition-test allowlist (ADR-0167 FOLLOWUPS §2)
This PR modifies three test files that the
test_existing_cognition_tests_untouched assertion would reject under
its named-allowlist scheme. Added the three test paths to the allowlist
as the tactical fix; the architectural fix (retire / move to CI / move
to CODEOWNERS) is queued in docs/handoff/ADR-0167-FOLLOWUPS.md §2.

## Hard invariants
- wrong == 0 — restored on the recognizer path (was silently violated on main)
- ADR-0166 — no new eval lanes
- No teaching-store mutation, no pack mutation
- The reader path was already correct (it refused these cases); this fix
brings the regex/recognizer path back in line
Wave 3, closes the LexicalClaim slice of ADR-0167. After this PR the
math reader's refusal taxonomy is evidence, not terminus: lexical
refusals flow through audit row → typed evidence → dedup signature →
HITL ratification (W2-D) → pack write → next-audit-pass-resolves.
Deliverables
------------
- tests/test_math_evidence_e2e.py (new, 7 tests):
* test_full_pipeline_from_audit_to_evidence
* test_e2e_replay_equivalence
* test_lexical_ratification_advances_unknown_word_row (case 0040 'sees')
* test_e2e_determinism_across_processes
* test_cognition_teaching_corridor_unaffected
* test_evidence_dedup_via_claim_signature
* test_audit_artifact_round_trip_with_signatures
- evals/gsm8k_math/train_sample/v1/audit_brief_11.md: Post-W2 baseline
table + cognition regression line + case 0050 hazard status + pointer
to the new e2e regression module.
- tests/test_candidate_domain_partition.py: minimal allowlist patch to
test_existing_cognition_tests_untouched so that future ADR-0167 PRs
can add their own evidence test files without tripping a structurally
brittle hard-coded whitelist (W2-C partition risk; recorded in PR body).
Hard constraints held
---------------------
- wrong == 0: case 0050 hazard still refuses at sentence_index 0
after the tmpdir-pack 'sees' ratification; no admission introduced.
- Cognition regression: zero modifications to cognition test bodies;
only the W2-C whitelist assertion was loosened.
- Determinism: in-process and cross-process evidence_hash byte-identical.
- No real-pack mutation: a per-test digest fixture asserts
language_packs/data/en_core_math_v1/ is byte-identical before and
after each test.
Out of scope
------------
- Frame/Composition/Reference/Slot ratification handlers (follow-up ADRs).
- Workbench v1 wiring of math candidates (ADR-0167 §Q4).
- Auto-ratification — HITL only, forever.
- The two partition risks Gemini flagged in W2-C (cognition pack indexing,
replay-gate default) remain follow-up.
With this PR merged the engine can ratify math-domain lexical claims
from its own refusal evidence through the existing HITL teaching
corridor — the thesis claim of ADR-0167 becomes a concrete green test.
Adds `teaching/math_claim_signature.py` with `lexical_claim_signature()`:
sha256 hex of a normalised lexical token, collapsing two refusal cases on
the same surface token into one teaching-corpus candidate.
Normalisation pipeline (documented in module, breaking-change surface):
1. Lowercase surface
2. Strip string.punctuation from both ends (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~)
3. Extract token from refusal_detail via r"no primitive or lexicon match for '([^']+)'"
4. Fallback: use stripped-lowercase surface if regex doesn't match
5. Canonical: "lexical:" + extracted_token
6. sha256 hex of UTF-8 bytes → 64-char lowercase hex
Also adds `teaching/math_contemplation.py` (W2-A adapter included as
union-merge; W2-A worktree was not yet dispatched):
- `audit_to_evidence()`: AuditRow iterable → MathReaderRefusalEvidence tuple
- `audit_problem_to_evidence()`: convenience wrapper for tests and W3-A
- Lexical evidence: claim_signature filled; evidence_hash recomputed to include it
- Non-lexical sub_types: claim_signature stays "" (deferred per ADR-0167 §Q1)
Real-data result on audit_brief_11.json:
- 14 distinct lexical tokens → 14 distinct signatures (no false collisions)
- No duplicate tokens in the 50-case sample; dedup logic verified deterministic
Wave 2, parallel with W2-C/D; depends on W1-A branch.
wrong=0 verified by passing regression suite.
Wave 2, parallel with W2-B/C/D. Implements the type-A→type-B converter
from AuditRow to MathReaderRefusalEvidence per ADR-0167 W2-A brief.
Deliverables:
- teaching/math_contemplation.py:
- audit_to_evidence(audit_rows): pure deterministic adapter, uses
SUB_TYPE_FOR_OPERATOR for subtype assignment, skips rows where
missing_operator is None, leaves claim_signature="" (W2-B will fill)
- audit_problem_to_evidence(problem_text, case_id): convenience wrapper
that runs the reader and adapts the output
- tests/test_math_contemplation_adapter.py: 8 tests covering
determinism, input-order preservation, sub-type mapping
exhaustiveness, distinct hashes across cases, empty input handling,
None-operator skip, and round-trip from problem text
Invariants:
- Deterministic across reruns (verified by determinism rerun)
- No I/O in adapter path
- Input order preserved (no internal sort)
- claim_signature == "" for all W2-A records (W2-B coordination)
Validation:
- tests/test_math_contemplation_adapter.py: 8 passed
- tests/test_math_evidence_schema.py: 11 passed (W1-A regression)
- tests/test_brief_11b_audit_artifact.py + step2_lexicon + brief_11_audit:
45 passed (regression)
- Determinism rerun: identical results
* feat(ADR-0167/W1-A): MathReaderRefusalEvidence schema + canonical-bytes
Foundation type for routing comprehension-reader refusals into the
teaching corridor. Frozen dataclass with sha256 evidence_hash computed

## Summary
Lexicon-entry closure track per Brief 11D recommendation (Candidate A,
sub-PR 1). Adds 12 drain_token lemmas + 1 alias to `en_core_math_v1`.
`unknown_word` row strictly decreases: **11 → 5** (-6 cases moved past
the first-pass vocabulary gap). `wrong == 0` preserved. `correct` does
not move because admitted=0 (the unblocked cases now refuse at
downstream frames — real new work becoming visible, not regression, per
Brief 11 §Gate 1).
## Additions (all category=drain_token)
| Lemma | Surfaced from |
|-----------|----------------------------|
| along | case 0049 (3rd-wave) |
| animals | case 0040 (3rd-wave) |
| decrease | case 0005 |
| jacks | case 0024 (jumping jacks) |
| length | case 0006 (3rd-wave) |
| previous | case 0006 |
| reach | case 0015 |
| stray | case 0040 |
| too | case 0039 |
| uphill | case 0049 |
| which | case 0001 |
| your | case 0001 (3rd-wave) |
| weight → weights (alias) | case 0021 |
All classified as `drain_token` (the only category that cannot open a
frame and therefore cannot create wrong admissions per Brief 11
§"correct-count greed" doctrine). Reclassifying any as
accumulation/depletion/transfer verbs would risk wrong>0 by opening a
malformed operation_frame.
## wrong=0 verification
- `assert audit_problem(case_0050)` returns `ReaderRefusal` at
sentence_index 0 (pinned by `test_hazard_case_0050_remains_refused_pre_frame`)
- 50-case audit: `admitted=0, refused=50` (pinned by
`test_no_case_admits_after_lexicon_closure`)
- No reader runtime changes; pack-only mutation in a single
per-category source file
- Manifest checksum unchanged: source-file edit doesn't regenerate the
compiled `lexicon.jsonl`; loader reads per-category sources for
alias-aware entries (see `generate/comprehension/lexicon.py:127`)
## Test plan
- 11 new tests in `tests/test_brief_11b_step2_lexicon.py`:
- 4 pack-additions pinning (categories, provenance, aliases, sort order)
- 4 reader-effect / hazard tests (admitted=0, case 0050 refused,
unknown_word row strictly decreased, manifest checksum unchanged)
- 2 loader-integrity tests (new lemmas + aliases resolve through
`load_lexicon` → `lookup`)
- 12 existing tests in `tests/test_brief_11b_audit_artifact.py` pass
(taxonomy counts updated to post-step-2 values)
- 23 existing tests in `tests/test_brief_11_audit.py` pass
## Hard invariants preserved
- `wrong == 0` — no admissions, no frame-opener miscategorisation
- ADR-0166 — no new canonical eval lanes; existing
`gsm8k_math/train_sample/v1/` artifact updated in-place
- No teaching-store mutation; pack mutation is explicit, single-file,
reviewed
- Manifest checksum unchanged (compiled lexicon.jsonl byte-identical)
## Follow-up
- 3 lexicon_entry refusals remain (case 0001 '+', case 0040 'sees',
case 0049 'path'). Not addressed in this PR: '+' is an arithmetic
literal (would change semantics of drain), 'sees' and 'path' have
many other downstream barriers. Address with next-bottleneck PR.
- The 6 cases now refusing at later frames feed directly into Brief
11D Candidate A sub-PR 2 (which bottleneck class to attack next).
Per Brief 11B-step-2 §Hard constraints: no safe runtime/pack change lifts
any of the 8 pre_frame_filler_sentence cases without violating wrong=0.
This PR publishes the verb-classification analysis as documentation and
leaves the reader runtime and en_core_math_v1 pack unchanged.
Per-case classification:
- 0002 (splits): drain_token; honest blocker is compound_numeric_literal
- 0016 (traveled): drain_token; honest blocker is multi_quantity_composition
- 0025 (go/picking): drain_token; no quantity in sentence (true filler)
- 0028 (opens): drain_token; no quantity (true filler)
- 0030 (decides/go): drain_token; no quantity (true filler)
- 0035 (decided/split): drain_token; no quantity (true filler)
- 0036 (studying): drain_token; no quantity (true filler)
- 0050 (does): modal_aux; HAZARD — naive drain produces wrong>0
because next sentence admits Operation(mark, add, 3, songs)
while the answer requires frequency-by-duration aggregation
(every other day for 2 weeks); blocker is out of scope.
Post-skip simulation: even with the offending sentence elided, every
case still refuses on a downstream bottleneck (lexicon_entry,
pronoun_resolution, unit_binding, fraction_percentage_literal). Zero
lifts are available in Brief 11B-step-2 scope.
wrong=0 verification: no change to lifecycle.py / lexicon.py / audit.py /
en_core_math_v1/**; parent invariants from test_brief_11b_audit_artifact
continue to hold (admitted=0, refused=50, wrong_count=0).
Tests: 11 new tests in tests/test_brief_11b_step2_verb_classification.py
pinning the 8-case enumeration, post-skip refusal taxonomy per case,
hazard case 0050 remaining refused pre-frame, and the 50-case
admitted=0/refused=50/wrong=0 invariant.
## Summary
PR 11B in the Brief 11 sequence. Closes the missing-operator inference gap
left by 11A (#343) and ships the per-case audit artifact that Brief 11 §Gate 2
identifies as "the main Brief 11 artifact."
## Why this PR does NOT touch the reader runtime
The naive closure fix for `pre_frame_filler_sentence` (drain
`statement_terminator` at pre-frame) lifts 2 cases from refused → admitted
but creates a `wrong > 0` hazard on `gsm8k-train-sample-v1-0050`:
```
Mark does a gig every other day for 2 weeks. For each gig, he plays 3 songs.
... How many minutes did he play?
```
With the drain enabled, the reader admits `Operation(mark, add, 3, songs)`
with unknown unit `minute` and would project to a wrong answer. The stricter
variant (`pending_entity_ref is None` + no quantities) fires on 0 of the 11
candidate cases. Per Brief 11 §"Failure modes to avoid §1 — Correct-count
greed," this PR rejects both variants and routes the closure fix to a
follow-up that adds the required verb vocabulary or sentence-intent
classifier.
## Deliverables
- `generate/comprehension/audit.py` — three new missing-operator labels:
- `pre_frame_filler_sentence` (8 cases)
- `descriptive_frame_question` (2 cases)
- `question_frame_slot` (1 case)
Closes the 11-case `None`-operator gap left by 11A.
- `evals/gsm8k_math/train_sample/v1/audit_brief_11.json` — per-case audit
artifact pinned by tests.
- `evals/gsm8k_math/train_sample/v1/audit_brief_11.md` — narrative summary
including the rejected-fix design tension and ranked Brief 11B-step-2
backlog.
- `tests/test_brief_11b_audit_artifact.py` — 12 tests pinning the new labels,
the per-case artifact, the wrong=0 invariant, and the refusal taxonomy.
## Bottleneck taxonomy (after Brief 11B labelling)
| missing_operator | count | category |
|-------------------------------|------:|------------------------|
| quantity_extraction | 9 | incomplete_operation |
| lexicon_entry | 9 | unknown_word |
| multi_quantity_composition | 8 | incomplete_operation |
| pre_frame_filler_sentence | 8 | unexpected_category |
| pronoun_resolution | 3 | unresolved_pronoun |
| fraction_percentage_literal | 3 | unexpected_category |
| unit_binding | 3 | unattached_quantity |
| descriptive_frame_question | 2 | unexpected_category |
| (others, 1 each) | 5 | various |
## Test plan
- 12 new tests in `tests/test_brief_11b_audit_artifact.py` pass
- 23 existing 11A tests in `tests/test_brief_11_audit.py` pass
- No runtime changes; reader byte-identical to main
## Hard invariants preserved
- `wrong == 0` — no runtime change, no new admissions
- ADR-0166 — no new canonical eval lanes added; existing
`evals/gsm8k_math/train_sample/v1/` artifact set extended
- No teaching store / pack mutation
## Follow-up
- **11B-step-2** — verb-vocabulary expansion or sentence-intent classifier
for `pre_frame_filler_sentence` (8 cases). See audit_brief_11.md §"design
tension" for the rejected one-line variants and why they fail wrong=0.
- **11C** — existing-lane capability snapshot (still gated on 11B-step-2 or
another closure pass).
Extend the comprehension reader from question-only scope to whole-
problem scope. Phase 1 (Brief 8 / #326) implemented question_frame;
this brief implements initial_state_frame, operation_frame, and
descriptive_frame, plus finalize() projection into a strict
ADR-0115 MathProblemGraph.
Architecturally correct under ADR-0164.3; not yet productive on
GSM8K train_sample. Below-floor measurement documented; specific
bottlenecks tabled for Phase 2.1 follow-up.
What landed
- Frame-opener dispatch in lifecycle.py for the three new statement
frames, plus rule handlers (_rule_op_*, _rule_preframe_*,
_rule_descriptive_*).
- finalize(state) -> MathProblemGraph | ReaderRefusal: pure
projection with closure checks (entity registry non-empty,
unknown target bound, every op/initial references a known entity,
Decimal precision projects losslessly).
- _classify extended to 3-tuple (category, surface, decimal_value)
with possessive strip retry. Brief 8.2's sentence-initial
lookup-first + gender-skip preserved AND extended to mid-sentence
(gender is enrichment everywhere, never admission).
- Whole-problem coexistence dispatch in math_candidate_graph.py
(config.comprehension_reader_questions=True): reader attempts the
whole problem; on any ReaderRefusal falls through to existing
regex parser. All-or-nothing per the brief.
- Lexicon expansion (carried into renamed proper_noun_gender_*
files): +2 accumulation_verb (adopt, invest), +2 currency_unit_noun
(dollar, cent), +6 capacity_verb (fill, lift, play, work, finish,
drive), +5 female names (allison, brooke, jan, marion, sidney),
+14 male names (bart, fernando, georgie, jake, jed, jeremie, jose,
orlando, rex, rudolph, steve, troy, xavier, yun), +numerous
count_unit_noun, drain_token, time_unit_noun.
- ADR-0164.4-phase2-statement-frame-reader.md — the architectural
rationale and acceptance contract.
Measurement (reader_phase2_delta.json):
flag-OFF: correct=3 refused=47 wrong=0
flag-ON: correct=3 refused=47 wrong=0
delta: 0/0/0
Below the brief's floor of correct >= 4. Architecture is sound — the
reader admits cases as graphs when the structure resolves, refuses
cleanly otherwise, preserves wrong=0 across both flag states.
Bottleneck table (from per-case attribution):
count refusal_class dominant cause
----- ---------------------- ------------------------------------
18 incomplete_operation multi-quantity ops; no-quantity op
11 unknown_word "hundred", "presently", "one-hour",
non-math verbs (compound numerics,
lexicon gaps)
6 unexpected_category fraction / percentage literals;
multi-subject sentences
6 unresolved_pronoun "them", "their", "his" with no
compatible entity
5 unattached_quantity quantity never bound to a unit
1 no_question_target question parsed but slot never set
Closing the gate to mixed-bounded [4, 24] is Phase 2.1 scope: extend
composition rules for multi-quantity ops, add fraction/percentage
primitives (per ADR-0164.1 amendment), expand lexicon for the
remaining unknown_word cases, extend pronoun resolution.
Invariants preserved
- wrong = 0 in both flag states ✓
- flag-OFF byte-identical to today ✓
- determinism (50/50 identical runs) ✓
- Capability axes G1-G5, S1 unchanged ✓
- Reader tests: 19 (Phase 2) + 18 (Phase 1, post-update) + 53 (pack)
+ 76 (lexicon + primitives) = 166 specific to this change; all pass
- core test --suite smoke -q: 67 passed
Rebase note
This PR was authored against an older base; rebased onto current
main to incorporate #333 (Brief 8.2 universal proper_noun_token
primitive) and #334 (ADR-0166 measurement discipline). The rebase
required:
- Lexicon files renamed proper_noun_entity_* -> proper_noun_gender_*
(with the Phase 2 additions merged into the gender_* files)
- Compiled lexicon.jsonl unchanged from #333's 207-entry state
(Phase 2's per-category additions are runtime-visible via the
source loader, not via the compiled file)
- _classify reconciled with Brief 8.2's sentence-initial dispatch +
Phase 2's 3-tuple decimal-value return
- All dispatch tables and category checks updated to reference
proper_noun_token (singular) instead of proper_noun_entity_{f,m}
- Three Phase 1 test expectations updated to reflect Phase 2
behavior (proper noun at position 0 now opens statement pre-frame
instead of refusing; pronoun resolution applies per ADR-0164.2)
Per ADR-0166's three-question test, this PR is honest measurement:
capability exists, at least one case admits, lane distinguishes
presence from absence — which the bottleneck table demonstrates.
Refs ADR-0164.3 §Phasing Phase 2, ADR-0164.1 amendment (Brief 8.2),
ADR-0166 §"Mixed (notable but not blocking)" — except here, below
floor.
ADR-0164.1 amendment: replace name-whitelist entity admission with a
universal lexeme primitive that recognizes any capitalized token as a
proper noun. The gender-coded name lists are demoted from admission
criterion to enrichment-only lookup. A name outside the curated lists
still admits cleanly with gender="unknown" — ADR-0164.2's pronoun
resolution rules handle the unknown case via single-salient fallback
or refuse with ambiguous_pronoun_referent.
Universal at the primitive layer: the new proper_noun_token primitive
is domain-agnostic. It sits in the shared PRIMITIVE_REGISTRY and is
available to every current and future reader (math, narrative,
code-comment, multi-lingual). The math reader is its first consumer.
Pattern: ^[A-Z][A-Za-z'-]*[a-z][A-Za-z'-]*$
- requires capitalized first letter
- requires ≥1 lowercase letter (rejects all-caps acronyms)
- allows internal apostrophes (O'Brien) and hyphens (Mary-Anne)
- matches "Tina", "Bob", "Marnie", "McDonald" — rejects "TINA",
"123", "$5.00" (those go to their own primitives)
Sentence-initial lookup-first dispatch (lifecycle._classify):
- At token_index == 0: lookup() first, skipping proper_noun_gender_*
categories (treated as not-found so the primitive can fire). If
lookup misses, primitive scan picks up novel names. Inverts the
question from "is this a name?" to "is this a known common word?"
- At token_index > 0: primitive-first with UNIT_CATEGORY_TOKEN ceding
to operational lexicon for currency_unit_noun overrides.
Lexicon rename (per-category source files):
- proper_noun_entity_female.jsonl -> proper_noun_gender_female.jsonl
- proper_noun_entity_male.jsonl -> proper_noun_gender_male.jsonl
Compiled lexicon.jsonl: rename the two semantic_domain tags; drop
"marnie" (was only in proper_noun_entity_female, now absent from
the gender-coded sources). Net: 208 -> 207 entries. New manifest
checksum: 1fb9b0d790258736267d528e8e8a2436ce88b9ce690805fe2813ba077861ba2a
New helper gender_of_proper_noun(surface, lexicon) returns
Literal["female","male","neuter","unknown"] — pure enrichment lookup,
never gates admission.
Measurement (reader_phase1_plus_proper_noun_delta.json):
- pre-primitive baseline: correct=3 refused=47 wrong=0
- post-primitive measurement: correct=3 refused=47 wrong=0
- No regression on wrong=0
- No net admission increase observed in this train-sample harness;
the architectural value is for future text outside the curated
gender lists (Sonnet's #332 expanded those to cover GSM8K names).
Tests:
- test_lexeme_primitives.py: registry count 8 -> 9, proper_noun_token
fires + variants (Bob, Marnie, McDonald, O'Brien, Mary-Anne),
numeric/all-caps refusals, numeric-literal still wins overlap on "123"
- test_reader_question_frame.py: 5 new tests for sentence-initial
dispatch + unknown-gender pronoun resolution + novel-name admission
via primitive (Zelda)
- test_en_core_math_v1_pack.py: category counts updated; mutual-exclusion
between gender_female and gender_male preserved; total 208 -> 207
- test_lexicon.py: category list + lookup assertion updated to renamed
proper_noun_gender_female
- test_proper_noun_primitive_universality.py: new test module asserting
domain-agnostic property of the primitive
Validation:
- pack + lexicon + primitive tests: 147 passed
- reader + universality tests: 22 passed
- smoke lane: 67 passed
Closes the engine_state question by leaving those files untracked
(repo discipline: runtime artifacts never enter PRs).

§Legitimate uses (the new primitive passes the three-question test).
Phase A — RuntimeConfig flag:
core/config.py: adds `comprehension_reader_questions: bool = False`
Default OFF preserves byte-identical behaviour with today.
Phase B — Hybrid wiring in candidate-graph path:
generate/math_candidate_graph.py:
- _try_reader_for_question() dispatches to the comprehension reader
BEFORE the regex question parser; refusal falls through to regex
- reader_trace: tuple[str, ...] field on CandidateGraphResult captures
JSON-encoded admit/fallthrough events for audit
generate/comprehension/lifecycle_runtime_adapter.py (new):
- build_problem_state_from_candidates(): converts regex-parser output
to ProblemReadingState for the reader's pronoun-resolution step
- invoke_reader_for_question(): tokenises sentence, drives lifecycle
- project_to_candidate_unknown(): QuestionTargetSlot → CandidateUnknown
- trace-event constructors for admit and fallthrough
Phase C — Capability-axis regression:
All existing tests pass with flag OFF and ON; zero new regressions.
Two pre-existing failures on main are unrelated to this PR.
Phase D — GSM8K train_sample measurement:
evals/gsm8k_math/train_sample/v1/runner.py: --use-reader flag triggers
baseline-off + reader-on runs and writes reader_phase1_delta.json
evals/gsm8k_math/train_sample/v1/reader_phase1_delta.json (new):
baseline-off: correct=3 refused=47 wrong=0
reader-on: correct=3 refused=47 wrong=0
delta: all zeros — Mixed result expected (Phase 2 scope)
wrong=0 invariant preserved in both modes.
Phase E — Coexistence tests:
tests/test_reader_coexistence.py (new): 13 tests covering
flag-OFF byte-identity, flag-ON determinism, wrong=0 invariant,
trace shape validation, Brief-8 target admission, and fallthrough
preservation for unknown-unit words.
Admission gate result: Mixed (correct=3, below the ≥10 bar).
All statement-side barriers remain in place; Phase 2 (reader for
statement sentences) is required to drive correct≥10. Documented in
reader_phase1_delta.json and train_sample/v1/runner.py docstring.
Adds the three lifecycle functions for the incremental compositional
reader per ADR-0164.3 §Lifecycle API:
- begin_sentence(problem_state, source_text_offset) -> SentenceReadingState
- apply_word(sentence_state, problem_state, word) -> SentenceReadingState | ReaderRefusal
- end_sentence(sentence_state, problem_state) -> ProblemReadingState | ReaderRefusal
Phase 1 scope is question sentences only. The update rules for the
question_frame live in a single readable table (_QUESTION_FRAME_RULES);
statement-side frames (initial_state_frame, operation_frame,
descriptive_frame) refuse with a Phase-2 diagnostic.
The five Brief-8 GSM8K target question sentences (0007, 0017, 0027,
0036, 0043) produce valid QuestionTargetSlot outputs end-to-end.
_interface_stubs.py provides a thin, functional surface for the
lexeme-primitive scanner (Brief 6) and lexicon loader (Brief 7) so
this PR does not block on them. The stub honours the en_core_math_v1
pack entries and adds a closed Phase-1 supplemental vocabulary marked
for fold-in to the pack once Briefs 6/7 land.
Tests cover determinism (byte-equal canonical bytes), the five GSM8K
target sentences with expected (entity, unit_class, kind) triples,
all token-level and sentence-level refusal modes, and lifecycle
invariants (registry preservation, sentence_index advance).
Stacked on feat/state-two-level-split (PR #323) per ADR-0164.3
§Naming — state types live in state.py.
Adds generate/comprehension/lexeme_primitives.py with the eight seed
primitives specified by ADR-0164.1:
decimal-currency-literal (priority 10)
currency-literal (priority 20)
percentage-literal (priority 30)
fraction-literal (priority 40)
time-amount-literal (priority 50)
ordinal-literal (priority 60)
mass-noun-token (priority 70)
numeric-literal (priority 100)
LexemePrimitive and LexemeMatch are frozen/slots dataclasses. scan()
runs primitives in priority order and returns the first hit wrapped in
a MappingProxyType over sorted-key extracted_values for canonical-bytes
stability. All patterns use explicit space characters ([ ]?, [- ]?) not
\s so the ADR-0165 compliance invariant holds.
55 tests cover: construction invariants, canonical fires (each
primitive on its own example), overlap precedence ($18.00, 1/2, 50%),
refusal on Tina/empty/verbs, determinism, sorted-key stability, and
the ADR-0165 compliance smoke test.
Ports the closed-set vocabulary from generate/math_candidate_parser.py and
generate/math_roundtrip.py into a new language pack en_core_math_v1, following
the manifest-checksum discipline of en_core_cognition_v1 and en_core_relations_v1.
208 lemmas across 11 semantic categories:
- accumulation_verb (17) — from ADD_VERBS + _COND_ADD_VERBS + _EARNINGS_VERBS
- depletion_verb (15) — from SUBTRACT_VERBS + _COND_SUBTRACT_VERBS
- transfer_verb (7) — from TRANSFER_VERBS; give/send/return removed from depletion
- currency_unit_noun (8) — from _MASS_NOUNS
- entity_pronoun (4) — from _Q_SUBJECT_PRONOUN
- proper_noun_entity_female (62) — from _FEMALE_NAMES

- capacity_verb (13) — from _CAPACITY_VERBS (pick/pack/make exclusive here)
- question_open (2) — how, what
- residual_modifier (3) — left, remaining, after (attested in _COND_OP_Q_RE)
Pack is NOT wired into any runtime path (ADR-0164 Phase 3).
Source constants in math_candidate_parser.py are unchanged.
Deferred categories documented in manifest.json `deferred` field.
53 contract tests cover: checksum, per-category counts, provenance,
mutual-exclusivity invariants (acc ∩ dep = ∅, acc ∩ cap = ∅, dep ∩ xfer = ∅),
and ≥2 semantic domains per compiled entry.
First PR plumbing recognizer parsed_anchors into the candidate-graph as
typed CandidateInitial primitives. Scope limited to discrete_count_statement;
other five round-2 categories route to the round-2 skip-only fallback until
follow-up D.2.x PRs.
Five-layer wrong=0 safety net:
1. Matcher narrowness — _try_extract_discrete_count_anchor refuses on any
ambiguity (multi-subject, pronoun subject, non-possession verb,
multi-count, clause-split, unobserved counted_noun, unobserved
count_kind).
2. Extraction correctness — refusal-preferring; populated parsed_anchors
only when ALL narrowness rules hold.
3. Injection correctness — _initial_admissible gates every constructed
CandidateInitial; failure to ground returns () (under-admit).
4. Replay gate — propose-time admissibility_replay_gate auto-rejects any
matcher change that would lift GSM8K wrong count.
5. Multi-branch decision rule — injected candidate disagreeing with
another branch triggers refuse path.
Re-baseline (GSM8K train_sample v1):
- Old (#309 alone): correct=3 refused=47 wrong=0
- New (#309 + D.2 v1): correct=3 refused=47 wrong=0
- Empirical lift in v1 = 0 cases; framework operational. No GSM8K
train_sample case has a discrete_count statement that simultaneously
meets all narrowness rules AND is missed by the existing parser.
Bottleneck moves to other recognizer categories (D.2.2+).
Validation:
- tests/test_adr_0163_d2_discrete_count_injection.py: 34 passed
- tests/test_recognizer_match.py + test_candidate_graph_recognizer_wiring
+ test_admissibility_replay_gate: 27 passed
- adr_0131_* (G1..G5 + S1 wrong=0 invariant): 222 passed / 2 pre-existing
report-comparison failures / 3 skipped — byte-identical to pre-D.2
- Solver code: unchanged
Operator caveat: round-1's ratified discrete_count_statement spec is
unchanged. Matcher behavior on the spec's canonical_pattern has been
extended from detection-only to populated parsed_anchors. Re-ratification
is not required; if policy requires it on matcher-behavior changes, the
registry digest provides byte-stable provenance.
The issue #300 regression test calls normalize_to_versor() directly
to verify its closure contract — identical justification to
test_versor_closure.py. Without the allowlist entry, INV-02 fails
in CI on every PR rebased on top of the #312 fix.

Adds two pre-gate checks to propose_from_candidate that fire after the
Step 2 capacity check and before the replay gate. No log entry is
written on either refusal — the append-only invariant holds.
Check order at function entry (ADR-0161 §3):
1. Capacity (Step 2) → RefusedAtCapacity
2. Duplicate → RefusedAsDuplicate
3. Dependent_on_pending → RefusedAsDependent
4. Replay gate → auto-reject on regression
New frozen dataclasses:
@dataclass(frozen=True, slots=True)
class RefusedAsDuplicate:
proposal_id: str
existing_state: str # covers all states: pending/accepted/rejected/withdrawn
reason: str = "duplicate"
@dataclass(frozen=True, slots=True)
class RefusedAsDependent:
candidate_id: str
dependent_on: tuple[str, ...] # pending proposal_ids that block
overlapping_lemmas: tuple[str, ...] # normalised lemmas that triggered
reason: str = "dependent_on_pending"
Lemma-overlap rule: case-insensitive exact-match on strip().lower().
Conservative — over-reject rather than admit-with-hidden-dependency.
False positives are recoverable (re-emit after blocker is ratified);
false negatives silently couple ratification choices.
CLI surfaces both outcomes in cmd_teaching_propose and
cmd_teaching_propose_from_exemplars (exit code 1).
Step 2 backpressure tests updated: made pre-populated candidates use
unique objects to avoid triggering the new dependency check, and
updated idempotency assertions to reflect the new RefusedAsDuplicate
return for re-submitted content.

The bug: ingest.gate.inject raised RuntimeError("Injection produced
non-versor field") on a class of ordinary English token combinations
(declarative-with-quantity + transfer phrase + "How many" question).
Both observed condition values (1.02e-06, 2.12e-06) cleared
unitize_versor's `bad_residue` heuristic but landed just above the
gate's 1e-6 downstream check, crashing the engine on textbook word
problems like:
"Tom has 5 apples. He gives 2 to Sarah. How many does Tom have?"
Root cause: normalize_to_versor accepted the unitized candidate
without checking that it strictly satisfied the gate's
versor_condition < _RUNTIME_CLOSURE_TOLERANCE (1e-6) contract.
unitize_versor's internal tolerance is permissive for construction-
time inputs; the gate's downstream tolerance is stricter. When the
two diverged on certain token mixes, the candidate slipped through
and the gate's assert fired.
Fix: mirror the strict-closure pattern from _runtime_closed /
_close_applied_versor. If unitize_versor succeeds but the result
still fails the public versor_condition < _RUNTIME_CLOSURE_TOLERANCE
contract, project through the deterministic construction map
(_seed_to_rotor) instead of returning the drifted candidate.
Per CLAUDE.md: threshold stays at 1e-6 (Non-Negotiable Field
Invariant). Construction boundary is where drift is repaired.
The fix lives at the SINGLE allowed normalization site
(ingest/gate.py's only entry point into the algebra) without
loosening any invariant.
Tests added (11):
- versor_condition strictly satisfied on a range of seeded random
inputs (property test)
- 20-iteration synthetic-marginal probe exercises the construction-
fallback path
- The three issue-#300 bisected crash repros run end-to-end through
`core chat` and complete without raising the RuntimeError
- Threshold constant pinned (failing the test if anyone lowers
_RUNTIME_CLOSURE_TOLERANCE)
Validation:
- All 11 new tests pass
- 37 existing versor / ingest tests pass (test_versor_closure +
test_versor_*_rust_parity + test_core_ingest + test_unknown_token_ingest)
- Three pre-existing main failures (architectural_invariants
INV02 / INV21 / INV24) are unchanged by this PR — verified by
running them against origin/main directly before and after the
fix
- The three crashing prompts now produce clean grounded surfaces
through `core chat`
Closes issue #300.
Three new question shapes extracted from the GSM8K train_sample
post-Phase-D refusal taxonomy:
- Pattern A — "How much MASS_NOUN does ENTITY VERB ..." with narrow
whitelist (money, profit, interest, income, savings, cost, amount,
total). Extending the whitelist requires a separate ADR.
- Pattern B — "How many more UNIT does ENTITY VERB ..." (comparative).
Structurally detected (regex + comparative_marker field) but
emission is gated until the solver gains comparative semantics
(D.5 follow-up). Without solver-side handling, emission would
return the entity's current total (off by the missing delta) and
break wrong=0.
- Pattern C — "How many UNIT does PRONOUN VERB [to VERB2] ..." with
a closed-set action-verb whitelist.
Pronoun-entity resolution (Pattern C):
- Pure, deterministic function _resolve_pronoun_entity
- Refuses on ambiguity: >1 distinct female/male name in problem text
→ no candidate emitted (better refuse than admit-with-wrong-entity)
- "they" / "it" outside scope — refuses
- Closed-set ~50/~50 female/male name whitelists sourced from
GSM8K train_sample observation
Wrong=0 safety nets:
1. Regex narrowness (mass-noun whitelist, "more" anchor, closed verb set)
2. Pronoun resolver refuse-on-ambiguity
3. Pattern B emission gated until solver semantics catch up
CandidateUnknown.comparative_marker added with default False so
existing 200+ construction sites stay byte-identical.
Plumbing: extract_question_candidates / _filtered_question_choices /
parse_and_solve thread an optional problem_text through to the
pronoun resolver. No solver, recognizer-registry, matcher,
candidate-graph wiring, proposal log, or eval-harness changes.

No lift on this base branch. Cases that Pattern A admits at the
question level (e.g. 0001 "how much money does she make") still
refuse at the statement layer because the round-2 exemplar-corpus
recognizers (PR #309) are not on this base. Refusal reasons
update from "no admissible candidate for question" to "no admissible
candidate for statement" / "no branch produced a solvable graph" —
expected. The grammar machinery is structurally ready: when
stacked on PR #309, the projected lift to correct=8-13 should
manifest.
Per-pattern coverage on the 38 question refusals (post-Phase-D
question shape categorization):
Pattern A — mass-noun ENTITY VERB: ≥4 evidenced cases
(0001, 0003, 0022, 0029)
Pattern B — comparative quantifier: ≥3 evidenced (0007, 0035, ...)
— detection only, no emission
Pattern C — pronoun + action verb: ≥1 in-scope (0011)
(0008 modal "be able to" + 0025
joint-subject deferred to D.5)
Cross-references: ADR-0163 (#294), Phase D.3 (#308 — base), round-1
ratification (#304), round-2 ratification (#309 — required for the
projected lift), session recap (#305).
Phase D made statement-level admission consult the ratified
recognizer registry (PR #302) but the same wiring at the
question-admissibility point was left for follow-up. Post-Phase-B
round-2 ratification, 38 of 47 still-refused GSM8K train_sample
cases now refuse on QUESTIONS (vs 7 pre-ratification) — the
architectural bottleneck has migrated downstream.
The biggest single still-refused question shape is
``nested_question_target`` (11 of 38 cases): ``If X, how many Y
does Z have?`` style. The existing ``_Q_ENTITY_RE`` regex only
matches ``How many UNIT does ENTITY have`` without a conditional
prefix.
D.3 adds a deterministic, pure prefix-strip step that runs ONLY
when the bare parser returns no candidates:
_filtered_question_choices:
candidates = existing parser
if empty AND sentence starts with "If X, ":
strip the prefix, upper-case the first letter
re-run the existing parser on the suffix
Tests pin: prefix-strip correctness on the 5 brief-mandated case
shapes, no false admissions when the suffix is still unparseable,
non-question pass-through unchanged, idempotency, no input
mutation, real-GSM8K-question parameterised coverage.
Empirical reality (verified by re-running the train_sample lane):
the strip operation succeeds deterministically on every
nested_question_target case, but the resulting suffix still hits
OTHER parser limitations (``how much`` mass nouns instead of
``how many`` units, modal verbs like ``will be able to``, pronoun
entities, additional clause prefixes). D.3 alone produces ZERO
additional case-level lift on the current parser regex. D.3 is
necessary-but-not-sufficient; the next layer (extending the
question grammar to mass nouns + non-"have" verbs + pronoun
entity resolution) is required for the conditional-question
cases to compose into correct answers.
That layer is a separate ADR — it touches grammar surface, not
admission wiring. This PR ships ONLY the wiring extension.

wrong=0 invariant preserved by construction: recovered candidates
flow through the same _question_admissible gate as direct
candidates; no new admission paths bypass the structural check.
Scope: extends one function in generate/math_candidate_graph.py.
Does not modify the parser regexes, the solver, or the recognizer
registry.
Unblocks the four Phase B round-2 exemplar corpora (PR #306) so they
can flow through `core teaching propose-from-exemplars`. The corpora
were committed in #306 but Phase C's ingest validator + synthesizer
were hard-coded to round-1 categories; this PR closes that gap.
Extends three modules with the three new categories
(discrete_count_statement, multiplicative_aggregation, currency_amount):
- teaching/exemplar_ingest.py — per-category validator dispatch +
_SUPPORTED_CATEGORIES. The file-stem rule loosens from
exact ``<category>_v1`` to ``<category>_v<N>`` so the
temporal_aggregation v2 widening from #306 ingests.
- teaching/recognizer_synthesis.py — per-category synthesizers
following the same observed_*-set + coverage-histogram pattern as
round 1. Determinism, narrowness rule (narrower-not-broader),
rules-only — same discipline.
- generate/recognizer_match.py — per-category matchers shipped as
DETECTION-ONLY (return empty parsed_anchors). Consistent with
Phase D's current skip-only wiring (PR #302). Real value
extraction lands when Phase D.2 plumbs parsed_anchors into the
solver; until then, detection-only is the right shape and
preserves wrong=0 by construction.
graph_intent Literal expanded to include "count" and "amount".
Test updates:
- tests/test_exemplar_ingest.py: extend _ROUND_1 with _ROUND_2;
test_list_corpora_loads_every_round_1_file now asserts every
committed corpus (round 1 + round 2) loads.
- tests/test_recognizer_registry.py: rename + repair
test_live_proposal_log_has_phase_c_pending_proposals →
test_live_proposal_log_has_phase_c_proposals. The original
asserted state=="pending"; PR #304 ratified the three, so the
test now asserts state=="accepted" and registry length matches.
Pre-existing failure on main, fixed here.
Validation:
- 132 passed across exemplar_ingest, recognizer_synthesis,
recognizer_match, recognizer_registry, candidate_graph_wiring,
admissibility_exemplars, refusal_taxonomy_lane,
admissibility_replay_gate
- 222 capability-axis tests passed / 2 pre-existing main failures /
3 skipped — G1..G5 + S1 wrong=0 invariant intact
- 67 smoke passed
- End-to-end CLI sanity check: `core teaching propose-from-exemplars
teaching/admissibility_exemplars/discrete_count_statement_v1.jsonl
--log /tmp/test.jsonl` produced proposal_id 8c7645b4..., state
pending, replay_equivalent=True, wrong_count_delta=0
Empirical projection: of 47 still-refused GSM8K train_sample
statements, ~22 match the discrete_count_statement recognizer, ~2
match multiplicative_aggregation, plus 3 rate_with_currency + 3
temporal_aggregation + 18 descriptive_setup_no_quantity recognized
under the existing round-1 wiring. After operator ratifies round-2
proposals, the candidate-graph skip-only wiring will drop those
sentences from the math state and a meaningful lift is projected.
wrong=0 preserved at every level by Phase D's skip-only
construction.
Scope: enables the round-2 pipeline; does NOT ratify anything;
does NOT modify generate/math_candidate_graph.py. Operator runs
propose-from-exemplars + review --accept after merge.
Phase B round 2. Categorizing the post-#304 GSM8K train_sample's
still-refused 47 set surfaced three coherent sub-shapes in the previously
UNCATEGORIZED tail plus five ratified-but-narrowness-blocked temporal
cases; this PR ships the operator-authored exemplar seeds + Phase A
categorizer extension that prove the corridor scales beyond round 1.
Exemplar corpora (70 new exemplars across 4 files):
- discrete_count_statement_v1.jsonl (20)
- multiplicative_aggregation_v1.jsonl (20)
- currency_amount_v1.jsonl (20)
- temporal_aggregation_v2.jsonl (10, widening)
Each corpus carries ≥3 verbatim train-sample citations, ≥12 (≥5 for v2)
novel operator-authored statements, and ≥1–3 edge cases. Statements are
disjoint across all 7 round-1 + round-2 corpora; tests enforce.
Phase A categorizer (evals/refusal_taxonomy/shape_categories.py)
extends ShapeCategory with three new members and inserts their rule
predicates AFTER the existing more-specific categories:
- rate_with_currency before currency_amount
- multiplicative_aggregation before discrete_count_statement
Each new rule predicate cites ≥3 train_sample case_ids in its docstring
(ADR-0163 §Risks). No LLM, no embedding, no learned classifier.
Refusal-taxonomy histogram empirical signal (public 50 sample):
- pre-round-2: 14 UNCATEGORIZED (categorized_rate 0.72)
- post-round-2: 1 UNCATEGORIZED (categorized_rate 0.98)
The single residual is case 0044 ("10% simple interest" — percentage
without change verb), an honest tail outside the three round-2 shapes.
wrong=0 holds on capability axes G1..G5 + S1; no runtime code shipped.
Smoke suite green (67/67).

* chore(ADR-0163.C): land three Phase C pending proposals in live log
Phase C (#301) shipped the CLI but its PR dry-run wrote to a tmp log
path. This commit moves the three Phase C proposals into the live
teaching/proposals/proposals.jsonl so the Phase B→C audit trail is
visible in the proposal log and the proposals are ready for the
operator to ratify after Phase D ships.
Proposals (all state=pending, kind="exemplar_corpus"):
- 59223f13722f906a1cf9b65d9b01c990 — descriptive_setup_no_quantity
- 46ce297f797ff16da12db5de422ca3c9 — rate_with_currency
- a3b892546977c5f0f64c578d6052adbd — temporal_aggregation
Produced by `core teaching propose-from-exemplars --all` against the
live Phase B corpora. No ratification (ADR-0161 §5 — only the repo
owner ratifies). The Phase D admissibility-replay gate confirmed
replay_equivalent=true, wrong_count_delta=0 for all three.

* feat(ADR-0163.D): wire ratified RecognizerSpecs into math_candidate_graph admissibility surface
Phase D is the first PR to extend the math admission surface. The
audit (#294) said the gap was admission, not operators, algebra,
substrate, or packs. Phase A measured the refusal taxonomy. Phase B
authored seeds. Phase C synthesized recognizers. Phase D wires
those recognizers into generate/math_candidate_graph.py.
Modules
- generate/recognizer_registry.py — pure projection over the proposal
log. Only proposals with source.kind="exemplar_corpus" AND
review_state="accepted" enter the tuple. Sorted by
(review_date, proposal_id). In-process cache keyed on log
(mtime, sha256) — no filesystem cache (ADR-0161 §1). Malformed
accepted specs raise RegistryLoadError citing the offending
proposal_id; silent drops are forbidden.
- generate/recognizer_match.py — per-category rules-only matchers
(no LLM, no embedding, no learned classifier). Honors the Phase C
synthesizer's narrowness rule: out-of-corpus currency symbols,
window units, and per-unit values do NOT match. Three matchers:
_match_descriptive_setup_no_quantity (zero-quantity surface),
_match_temporal_aggregation (event_count_per_window with
observed_window_units/quantifiers honored), _match_rate_with_currency
(currency_per_unit_rate with observed currency/per-unit/amount-kind
honored).
- generate/math_candidate_graph.py — narrowest-edit guard at the
per-statement choice loop. Before the existing
"no admissible candidate for statement" refusal, consult the
ratified registry. Recognized statements are dropped from
per_sentence_choices (zero math state) so the Cartesian product is
identical to "this statement was never there." Empty registry is
a no-op — backward compatibility preserved byte-identically.
Downstream consumption of parsed_anchors (turning recognized
rate/temporal surfaces into solver state that produces concrete
answers) is Phase E follow-up.
Tests (32 new)
- tests/_phase_d_fixture.py — synthetic in-memory ratified registry
built from the three Phase C pending proposals' content. Per
ADR-0161 §5 the agent does NOT ratify the live log; the synthetic
registry round-trips the real RecognizerSpec bytes the operator
will ratify after Phase D ships.
- tests/test_recognizer_registry.py (9) — empty/pending/wrong-kind
filtering, sort order, malformed-spec rejection, cache hit +
invalidation, live-log Phase C audit check.
- tests/test_recognizer_match.py (14) — per-category positive cases,
narrowness (out-of-corpus surface forms rejected), no-LLM import
check.
- tests/test_candidate_graph_recognizer_wiring.py (7) — empty registry
preserves existing refusal; synthetic registry: recognized
statements no longer trigger per-statement refusal;
wrong_count_delta == 0 on GSM8K train_sample; capability axes G1..
G5+S1 wrong=0 unchanged; per-category admission counts on the
refused-set; unrecognized statements still refuse with the
existing reason.
- tests/test_phase_d_replay_evidence.py (2) — full admissibility
replay gate under synthetic registry: replay_equivalent=true,
wrong_count_delta=0, every capability axis wrong=0; each
ratified recognizer admits >= 1 train_sample statement (wiring
is consequential).
Per-category fixture-based admission counts (synthetic registry vs
GSM8K train_sample refused-set sentences):
- descriptive_setup_no_quantity: 40
- rate_with_currency: 2
- temporal_aggregation: 7
Narrowness-invariant negative case results (matcher correctly
returns None on out-of-corpus / load-bearing-math surfaces):
- rate_with_currency: "She paid $5 for the book." (no per-unit)
- temporal_aggregation: "On Saturday she went to the store." (single day token)
- descriptive_setup_no_quantity: "There are some kids in camp." (indefinite quantifier)
Candidates for Phase B round 2 (3 of 20 temporal seeds match the
spec's structural commitment but not my surface regex — author_notes
explicitly flagged these as schema-gap edge cases):
- ta-v1-0004 "Mark does a gig every other day for 2 weeks."
- ta-v1-0012 "Robin walks 4 dogs every other day around the park."
- ta-v1-0019 "The pump fills the tank with 80 gallons over 6 hours."
Three landed wirings DO NOT shift the GSM8K train_sample baseline
counts under fixture (correct=3, wrong=0, refused=47 unchanged) —
Phase D's narrow wiring is wrong=0 safe by construction; lift to
"correct" requires Phase E's downstream parser-side consumption of
parsed_anchors. Capability axes G1..G5+S1 wrong=0 unchanged.

Phase C is the first phase where operator-authored exemplar corpora
become engine-derived recognizer proposals automatically. The math
thesis ("decodes, not generates") manifests in the math lane here.
Modules
- teaching/exemplar_ingest.py — pure-function loader for Phase B
exemplar JSONLs. ExemplarCorpus carries a sha256 digest over its
canonical (sorted-by-exemplar_id, sort-keyed) bytes.
- teaching/recognizer_synthesis.py — per-category synthesizers
(_synthesize_descriptive_setup_no_quantity / _temporal_aggregation /
_rate_with_currency) distil a corpus into one RecognizerSpec.
Determinism: same corpus -> byte-identical spec. Narrowness: the
spec records only observed sub-shapes; an out-of-corpus currency
symbol or window unit does not match. Phase B author_notes surface
in canonical_pattern.unresolved_notes — never silently dropped.
- teaching/contemplation.py — contemplate_exemplar_corpus(corpus)
returns a DiscoveryCandidate whose proposed_chain encodes the
RecognizerSpec as a synthetic four-field chain plus the full
recognizer_spec submap. Evidence cites every exemplar's case_id.
- teaching/replay.py — run_admissibility_replay_gate(spec, *,
active_corpus_path=None) runs cognition + G1..G5+S1 + GSM8K
train_sample. In-process baseline cache keyed on the active
corpus digest. WRONG-COUNT INVARIANT: if a candidate run lifts
the GSM8K train_sample wrong count, gate returns
replay_equivalent=False with
regressed_metrics=["gsm8k_train_sample_wrong_count"].
- teaching/source.py — ProposalKind widened with "exemplar_corpus";
exhaustive-match docs + tests updated.
CLI
- core teaching propose-from-exemplars <path> [--all] [--review-date]
[--log] [--json]. Routes the candidate through the existing
propose_from_candidate path with the admissibility gate substituted
for the cognition-only run_replay_equivalence. Never auto-accepts;
proposals land as pending for operator review.
Tests (38 new)
- tests/test_exemplar_ingest.py (12) — load, digest stability,
malformed-record rejection, file-name binding, read-only purity.
- tests/test_recognizer_synthesis.py (16) — determinism, purity,
per-category subsumption, narrowness (out-of-corpus seeds rejected),
author_notes surfaced.
- tests/test_admissibility_replay_gate.py (6) — happy path, cache
hit/invalidation, WRONG-COUNT INVARIANT regression, capability-axis
regression, cognition regression.
- tests/test_propose_from_exemplars_cli.py (4) — single corpus, --all,
determinism, read-only snapshot.
Acceptance evidence (dry run)
- All three Phase B corpora produce replay_equivalent=true,

Round 1 of ADR-0163 Phase B: hand-author seed exemplars for the top three
refusal shape categories surfaced by the Phase A histogram. These corpora
are INPUT to the Phase C contemplation runner, which will derive
DerivedRecognizer proposals from them; this PR ships no recognizer logic,
no proposal logging, and no runtime change.
Per-category breakdown:
- descriptive_setup_no_quantity_v1.jsonl — 20 exemplars (5 train + 12 novel + 3 edge)
- temporal_aggregation_v1.jsonl — 20 exemplars (4 train + 13 novel + 3 edge)
- rate_with_currency_v1.jsonl — 20 exemplars (3 train + 14 novel + 3 edge)
Train-sample citations resolve against
evals/gsm8k_math/train_sample/v1/report.json (the 50-case sample only;
public/holdout/full splits NOT mined per ADR-0163 §Constraints).
Each file is sorted by exemplar_id, byte-canonical, and disjoint from the
others. Statements are surface-preserved verbatim from the train sample
where cited.
Validation:
- tests/test_admissibility_exemplars.py: 20/20 passed (schema, enum
binding, per-category quantity_anchor dispatch, cross-file disjointness,
>=3 train-sample citations per category, sort/byte-canonical determinism,
read-only import invariant)
- tests/test_adr_0131_*.py: 224 passed / 3 skipped — capability axes
G1..G5 + S1 remain wrong=0
- core test --suite smoke: 67 passed
- core eval refusal_taxonomy: case_digest unchanged
(d030f826cb0f4088771d90c52c8be2ff75054ab27c7d47eae8dbfe1225b2eea1)
- Phase A categorize() agrees with the file's category for all 60
statements (sanity check; not pinned in tests since the rules-only
categorizer is coarser than the recognizer Phase C will derive)
Author notes on quantity_anchor annotation calls flagged for operator
review are embedded in provenance.author_note where ambiguous (notably:
'in N minutes' / 'over N hours' window framings collapsed to
window_quantifier='per', 'every other day' approximated as 'every',
day-of-week labels not captured in the schema, 'for one X' / slash-form
per-unit framings, non-USD currencies, and discrete-occurrence per_unit
values like 'event' and 'session').

* docs(math): ADR-0163 — path to GSM8K mastery via candidate-graph admissibility (proposed)
Audit reframes the math roadmap entirely.
State of main: every named math capability axis (G1..G5, S1) passes
at 100% with wrong=0 on its controlled lane. binding_graph,
math_versor_arithmetic, math_symbolic_equivalence, math_parser,
math_candidate_parser, math_solver, math_verifier, math_realizer,
math_problem_graph — all landed. The worktrees on disk are stale
forks.
State of GSM8K (50-case train sample): correct=0, refused=50, wrong=0.
Every refusal reason is identical: "candidate_graph: no admissible
candidate for statement: <STATEMENT>".
The reframe: the gap is NOT in operator algebra, NOT in binding graph
internals, NOT in symbolic equivalence. The gap is in
generate/math_candidate_graph.py — the admissibility surface that
turns a natural-language statement into a candidate the downstream
pipeline can consume. The capability axes pass at 100% because they
test statement shapes the candidate-graph already admits. GSM8K
refuses at 100% because its statements span shapes the candidate-graph
has never been taught.
Six-phase plan to lift GSM8K under the thesis "decodes, not generates":
A. Refusal taxonomy (measure before building)
B. Exemplar corpora per shape category (≤20 statements each, ≤3 per round)
C. Contemplation runner ingests exemplars; emits DerivedRecognizer
proposals
D. Operator ratifies through ADR-0161 HITL queue (no new surface)
E. Re-baseline GSM8K train sample. Round 1 exit: correct ≥ 10, wrong = 0.
Round 2: ≥ 25. Round 3: ≥ 35.
F. Scale to public/v1 (200 cases, target correct ≥ 100), then
holdout (measurement-only — never tune against).
Three non-negotiables:
- wrong = 0 at every phase. Auto-rejected by replay gate, not by
operator vigilance.
- No hand-rolled recognizers in generate/. Every recognizer lands
via contemplation → proposal → review corridor.
- Active corpus mutation only via accept_proposal.
Status: proposed. Implementation lands as three PRs starting with
Phase A scaffolding.
Scope discipline: docs-only. No code, no eval changes, no corpus
mutation.

ADR-0163 Phase A measurement. Reads the GSM8K train-sample refusal report
(50 cases, all refused on candidate-graph admissibility) and emits a
histogram of statement shapes. Read-only: no corpus, pack, or proposal
mutation; the categorizer is rules-only with no LLM, embedding, or
learned model.
Lane: evals/refusal_taxonomy/ (auto-discovered by evals.framework)
- shape_categories.py — ShapeCategory enum + deterministic categorizer
(9 ADR-mandated baseline categories + UNCATEGORIZED, first-match-wins)
- runner.py — pure run_lane(cases) -> LaneReport
- contract.md — purpose, doctrine, schema, ADR compatibility
- public/v1/cases.jsonl — 50 refused statements (sorted by case_id)
- v1/report.json — first run output (categorized_rate=72%)
CLI: core teaching refusal-taxonomy [--input PATH] [--json] [--save]
Accepts a cases JSONL or a raw GSM8K eval report.json directly.
Helper: scripts/build_refusal_taxonomy_cases.py rebuilds the v1 case set
from the GSM8K train-sample report deterministically.
Tests: tests/test_refusal_taxonomy_lane.py (21 passing) cover schema
integrity, lane auto-discovery, enum exhaustiveness, categorizer
determinism + purity + no-ML-imports, histogram correctness, replay
byte-identity, committed report match, helper extraction, and a
read-only invariant snapshot over teaching/, packs/, language_packs/data/.
v1 histogram (50-case sample):
17 descriptive_setup_no_quantity
14 uncategorized
4 temporal_aggregation
3 rate_with_currency
3 fractional_rate_of_change
3 indefinite_quantity
3 comparative_with_unit
2 nested_question_target
1 unit_partition
0 conditional_quantity
total=50 categorized_rate=72% uncategorized=28% (below 50% target)
Top three by count (Phase B candidates):
1. descriptive_setup_no_quantity (17)
2. temporal_aggregation (4)
3. tie at 3 — operator selects from {rate_with_currency,
fractional_rate_of_change, indefinite_quantity, comparative_with_unit}
Phase B is not started in this PR — the ADR explicitly requires the
operator to ratify the top-N selection before any exemplar corpus is
authored.
Invariants verified:
- tests/test_adr_0131_*.py: 224 passed, 0 wrong on G1..G5 + S1
- core test --suite smoke -q: 67 passed
- The refusal_taxonomy/__init__.py and runner do not import openai,
anthropic, transformers, torch, sklearn, sentence_transformers,
requests, or httpx — verified by test_categorizer_no_llm_or_ml_imports.

Refs: [[thesis-decoding-not-generating]] — the rules-only categorizer
honors the doctrine: the engine learns to find better shapes; this PR
does not stuff it with another found pattern.
