## 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.
## Test plan
uv run pytest tests/test_recognizer_skip_wrong_zero.py \
tests/test_math_candidate_graph.py \
tests/test_teaching_audit.py \
tests/test_candidate_domain_partition.py \
tests/test_math_evidence_e2e.py \
tests/test_math_evidence_schema.py \
tests/test_math_contemplation_adapter.py \
tests/test_math_claim_signature.py \
tests/test_math_lexical_ratification.py \
tests/test_brief_11b_audit_artifact.py \
tests/test_brief_11b_step2_lexicon.py \
tests/test_brief_11_audit.py
→ 152 passed
## 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

"""ADR-0126 P3 — tests for candidate-graph assembly + decision rule.
|
|
|
|
Proves the end-to-end candidate-graph pipeline:
|
|
|
|
text → per-sentence candidates → filter → branch enumeration
|
|
→ per-branch solve → decision rule → answer | refusal
|
|
|
|
Critical assertions:
|
|
|
|
- Unambiguous problems produce a single answer.
|
|
- Ambiguous-verb problems ('gives') resolve via the slot-count
|
|
tiebreaker; both readings agree on the answer, so emission proceeds.
|
|
- Out-of-grammar sentences refuse (no exception, deterministic
|
|
refusal_reason string).
|
|
- Branches that disagree on the answer refuse (wrong == 0 preserved).
|
|
- Permissive verbs that the legacy parser refused now produce answers.
