## 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
The full lane carried 13 long-standing red tests whose premises were
invalidated by reviewed-corpus growth that landed in earlier commits.
None reflected runtime bugs — all four classes are corpus-state drift
where the test fixture became stale. Curated lanes were green, full
lane stayed quietly red. Closes that gap.
1. test_teaching_audit (2 tests).
* test_audit_real_corpus_runs_clean asserted dropped == () and
lines_on_disk == lines_loaded — premise written before any
supersession existed. Curriculum saturation v2 (commit a0edbb4)
ratified the wisdom_grounds_judgment → wisdom_requires_knowledge
supersession; the audit now correctly shows 1 dropped line.
Rewritten as the line-conservation invariant:
lines_loaded + len(dropped) == lines_on_disk
plus a typed-reason check on every dropped entry.
* test_default_superseded_by_is_null_in_loaded_entries asserted
ALL loaded entries have superseded_by == None. Wrong even by
ADR-0055 design: the replacement entry IS loaded and carries
the back-pointer to the retired chain. Rewritten as the
active-set invariant: any non-null superseded_by on a loaded
entry must reference a dropped (retired) chain id, never a live
one — no double-live state.
2. test_learning_loop_demo (7 tests).
The demo's headline prompt was "Why does thought exist?", and the
ADR-0057 demo trilogy (commit 82dac4b) chose (thought, cause) as
the cold cell. Cognition saturation v2 (commit a0edbb4) ratified
cause_thought_reveals_meaning into the active corpus — so the
cold turn now grounds, no discovery candidate is emitted, every
demo scene breaks. Rotated the cold subject to ``narrative``
(pack-resident, no chain, same thematic shape, same affirming
evidence pointer cause_creation_reveals_meaning). Demo headline,
evals/learning_loop/run_demo.py, core/cli.py preamble, and the
test assertions all updated together so the demo reads cleanly:
before: [none] I don't know — insufficient grounding...
after : [teaching] narrative — teaching-grounded ... narrative
reveals meaning ...
3. test_discovery_candidates (4 tests).
Test fixture used (judgment, CAUSE) as the still-cold pair.
Epistemology v1 (commit 2acf71f) ratified
cause_judgment_requires_wisdom — (judgment, cause) is no longer
cold. Rotated to ``principle`` (pack-resident, no chain on either
intent today). Added a pytest.skip self-guard so when a future
curriculum unit ratifies a (principle, *) chain the test rotates
cleanly instead of going red.
Full lane: 1892 passed, 2 skipped, 0 failed (was 4 failed pre-fix,
13 failed pre-ADR-0063). Cognition eval unchanged: public 100/100/
91.7/100, holdout 100/100/83.3/100.
Lands the three load-bearing pieces of ADR-0055 Phase A so later
phases (DiscoveryCandidate, TeachingChainProposal) have a safe
substrate to write into.
- teaching/audit.py: pure, deterministic re-parse of the reviewed
corpus with same gates as the runtime loader but keeps drop
reasons (invalid_json, missing_required_field:*, unsupported_intent,
pack_missing_subject, pack_missing_object, superseded_by:*).
- teaching/provenance.py: typed Provenance(adr_id, source,
review_date, raw); legacy "reviewed" maps to "hand_authored" so
current corpus reports the canonical enum without a file rewrite.
- chat/teaching_grounding._corpus_index honors superseded_by —
active view drops superseded entries while disk preserves history.
- core teaching audit CLI subcommand (--json optional); exits 1 on
any drop so CI catches silent corpus shrinkage from pack swaps.
Observable behaviour unchanged: corpus is 10/10 loaded, all five
core lanes green (smoke 67, cognition 121, runtime 19, teaching 17,
packs 6), cognition eval metrics identical on dev / public /
holdout splits. versor_condition < 1e-6 invariant untouched.
Tests: tests/test_teaching_audit.py — 23 tests covering provenance
parser, real-corpus determinism, every drop-reason path,
supersession semantics, runtime/audit parity, read-only contract.
