INV-25 makes the GSM8K lesson structural: no capability claim is valid unless
its gold is computed by a procedure sharing no code with the system under test.
Three meaningfully-failing checks (proven able to fail): 25a oracle imports no
SUT module (AST); 25b every committed deductive gold is reproduced by the
independent oracle AND matched by the engine; 25c an unsound engine disagrees
on committed cases.
SHA-pin the deductive lane (deductive_logic_v1, dev+holdout+external 716/716,
wrong=0, refused=0) via a deterministic --report writer + run_as_module (the
lane dir's local generate.py shadows the package in script mode) + CLAIMS regen.
Fix drift the review surfaced: contract.md + pivot doc claimed an 8,000/7,340
fuzz and an 'external mirror' -> corrected to the real gated 3,000-case fuzz
(2,796 definite) and 'hand-authored, NOT a published-benchmark mirror'; pivot
doc GSM8K holdout 0->5 (all 5 are R1 reconstruction; composer scored 0).
Validated: smoke 78, deductive 23, proof 29, invariants 44, lane-sha+claims 9.
* chore(ratify): accept four Phase C round-2 recognizers (round 2)
Operator ratification of the four Phase B round-2 proposals per
ADR-0163:
- 8c7645b4 — discrete_count_statement
- 03627f6f — multiplicative_aggregation
- 00547671 — currency_amount
- 4d47a247 — temporal_aggregation (v2 widening)
All four passed Phase C's admissibility replay gate at propose-time:
replay_equivalent=True, wrong_count_delta=0. Each acceptance also
appends the synthetic admissibility chain to teaching/cognition_chains.
Post-ratification empirical signal (verified by running the
train_sample lane):
- correct: 3 (unchanged)
- refused: 47 (unchanged)
- wrong: 0 (unchanged — invariant holds)
The case-level lift did not materialize because the architectural
bottleneck migrated from STATEMENT admission to QUESTION admission.
44 of 47 cases now refuse on a QUESTION (vs 7 pre-ratification).
The four new recognizers' matchers fire on 36 of 47 first-failed
sentences, but the cases then refuse on a different (later)
sentence — typically the question itself.
The unlock for this round is Phase D.3 (conditional-prefix question
recovery, PR #308) + a follow-up parser-grammar extension to handle
mass nouns (how much), modal verbs (will be able to), and pronoun
entity resolution. Those touch grammar surface, not admission
wiring; separate ADR.
This PR commits the ratification audit trail. The lift composes
when Phase D.3 lands and the grammar layer follows.
wrong=0 invariant: preserved by Phase D's skip-only construction.
Statement-level recognizer matches contribute zero math state to
the Cartesian product; no recognizer can introduce a wrong answer
under skip-only semantics.

* chore(ratify): re-pin public_demo lane SHA after round-2 ratification
The four round-2 ratifications appended synthetic admissibility
chains to teaching/cognition_chains/cognition_chains_v1.jsonl,
which is consumed by the public_demo lane. The lane's deterministic
output SHA changed accordingly — drift confirmed by CI on origin
PR #309 (`✗ public_demo e323adb35ea17987.. expected 888ddd0d12635d70..`).
Re-pin per the standard remediation:
python scripts/verify_lane_shas.py --update
python scripts/generate_claims.py
This is the expected corpus-mutation cycle following ratification.
No code change, no test change. The new public_demo SHA reflects
the engine's new admissibility surface; the lane runner's output
is byte-stable under the new corpus.

* perf(tests): extract math_teaching_corpus lane from pytest into CI lane SHAs
The two slowest tests in the pytest suite were:
388s test_adr_0131_2_teaching_corpus_lane::test_report_is_byte_equal_across_runs
161s test_adr_0131_2_teaching_corpus_lane::test_lane_passes_exit_criterion
Both invoked build_report() from evals.math_teaching_corpus.v1.runner —
the canonical math-teaching-corpus lane runner — once for the exit
criterion and again for byte-equality. Together: 549s = 9m 9s, 30% of
the full pytest suite, recomputed on every developer run.
This is the exact 'lane runner invoked from pytest' anti-pattern that
the existing scripts/verify_lane_shas.py CI job is designed to absorb.
The other 7 lanes (reviewer_registry, miner_loop_closure, etc.) all
run in CI via SHA pinning rather than in pytest.
Changes:
scripts/verify_lane_shas.py — add math_teaching_corpus_v1 spec +
PINNED_SHAS entry (eaf160d145da29f9..., computed locally from
a clean run of the lane in this commit's tree).
scripts/generate_claims.py — add _LANE_ADR entry (ADR-0131) +
claim text. Failing fast on missing lanes is by design.
CLAIMS.md — regenerated; one new row.
tests/test_adr_0131_2_teaching_corpus_lane.py — delete TestLaneGate
class (2 tests, 549s). Retain TestDatasetIntegrity (5 tests),
TestBoundedDomain (2), TestHonestEvidence (1) — these are
fast (0.26s total) and pin contracts the lane runner does not
cover (dataset shape, lemma boundedness, evidence reachability).
Replace deletion with an explanatory comment block.
The deleted contracts are still enforced — just in CI instead of
pytest:
exit criterion → runner exit code (returns 1 on failure)
byte-equality → PINNED_SHAS verification (SHA-256 of report.json)
Verified locally:
scripts/verify_lane_shas.py — 8/8 lanes match pinned SHAs
pytest tests/test_adr_0131_2_teaching_corpus_lane.py — 8/8 pass in 0.26s
Expected full-suite delta: -549s (from ~30m to ~21m). Further speedup
will come from the upcoming full-pytest CI gate with pytest-xdist -n4.
* ci: bump lane-shas timeout 12m → 20m for new math_teaching_corpus lane
The math_teaching_corpus_v1 lane added in this PR runs in ~5-6 min,
pushing the total lane-shas job over the previous 12-min timeout.
First CI run cancelled at 12m17s. Bumping to 20m gives ~8m headroom.
* fix(ci): bump lane subprocess timeout 300s→900s + add math_teaching_corpus to test_lane_sha_verifier EXPECTED_LANES
Two issues surfaced by CI run on the prior commit:
1. The math_teaching_corpus lane takes ~142s wall-clock locally (3.79
cores × ~538s CPU). On CI's single/dual-core runner that translates
to ~5-9 min, exceeding the 300s subprocess timeout in
scripts/verify_lane_shas.py. Bumping to 900s gives ~60% headroom.
2. tests/test_lane_sha_verifier.py::TestExpectedLaneCoverage::test_all_expected_lanes_covered
hardcodes the expected lane set. Adding math_teaching_corpus_v1 to
LANE_SPECS triggered the 'extra lanes' assertion. Adding it to
EXPECTED_LANES (the file's own contract: 'if intentional, add here').
Closes W-015 wiring debt. Per Sonnet's investigation (PR #252,
verdict (c)): _slerp_toward interpolates on S^31 but the versor
manifold (Spin sub-group in Cl(4,1)) is a proper subset. Slerp's
geodesic doesn't stay on the manifold, producing systematic
off-manifold state that the post-hoc unitize_versor was repairing.
Fix replaces _slerp_toward with the proper rotor-geodesic path:
R = word_transition_rotor(field_state.F, anchor_field)
R_step = rotor_power(R, _ANCHOR_PULL_ALPHA)
pulled_F = versor_apply(R_step, field_state.F)
rotor_power stays on the manifold by construction (same principle
as generate/stream.py:220). versor_apply closes via algebra/
versor.py — an already-sanctioned site. The unsanctioned
unitize_versor call in _anchor_pull and the entire _slerp_toward
function are removed.
CLAUDE.md normalization-site discipline is now restored:
session/context.py:_anchor_pull no longer performs normalization.
Changes:
- session/context.py: import rotor_power + word_transition_rotor,
remove _slerp_toward (34 lines), rewrite _anchor_pull to use
rotor-geodesic (15 lines net change).
- tests/test_session_coherence.py: new test pins the manifold
invariant — after anchor pull, versor_condition stays < 1e-6
without any unitize call (32 lines).
Intentional lane re-pins (audit-trail per #229 discipline):
- demo_composition: 403be13b → 3a3d09f3 (anchor pull now produces
correct on-manifold fields; demo output shifts as expected).
- public_demo: acd51d0c → 888ddd0d (same cause).
CLAIMS.md regenerated to reflect new pins (per #239 lesson).
Verification:
- tests/test_session_coherence.py: 3 passed
- core test --suite smoke: 67 passed
- scripts/verify_lane_shas.py: 7/7 match (post-re-pin)
- Manifold invariant test pinned: anchor pull preserves
versor_condition < 1e-6 by construction (no repair).
Investigation source: PR #252 (Sonnet). 4,138-sample bimodal
distribution confirmed _slerp_toward as the sole drift source.
When a pinned lane drifts, the script prints actual/expected SHAs but
gives no guidance. Authors then have to look up that --update exists
and that CLAIMS.md needs regenerating alongside.
Adds a remediation block printed only on mismatch, listing the most
common drift sources (core/cognition/result.py, chat/runtime.py,
generate/realizer.py, capability registries) and the two commands
needed to re-pin: --update + generate_claims.py.
Why this is the right scope: branch protection now blocks merge on
red lane-shas CI (enabled 2026-05-24), so the remaining gap is
discoverability — telling authors what to do, not enforcing that
they do it. A one-line message change carries that signal without
adding hooks, templates, or infrastructure.
No behavior change on success.
Three lane SHA pins drifted because intentional surface/serialization
changes shipped without re-running scripts/verify_lane_shas.py --update.
Bisect attributing the drift:
- demo_composition + public_demo broke at 5cad0a4 (#118 ADR-0110
mathematics_logic → expert_demo) — the demos enumerate the expert set.
- demo_composition drifted a second time at ab4c7cb (#220 Phase 3
state tagging spine) — additional epistemic fields shifted the surface.
- domain_contract_validation broke at a45eab1 (#219 Phase 2 epistemic
bug repairs) — normative/epistemic field shape changed.
The in-tree canonical report for fabrication_control_summary was also
stale vs. its (correct) pin; refreshed here for byte-alignment.
After this commit: 7/7 lanes match pinned SHAs; verify_lane_shas.py
runs green locally and in CI.
Followup (separate PR): hook/template guard so future PRs that touch
core/cognition/result.py, chat/runtime.py, or capability registries
re-run --update before merge.
Two pre-existing latent issues fixed:
1. discourse_planner flag catalog drift (test_flag_report failure)
On 2026-05-21 the discourse_planner default was flipped to True
after byte-equality verification (per inline comment in
core/config.py:130-138), but the capability flag catalog at
core/capability/reporting.py was not updated — it still claimed
"flag_shipped_default_off". The test
test_flag_report_tracks_default_off_flags_without_enabling_them
correctly caught the inconsistency; it had been failing across
every commit since ADR-0092 first ran the suite.
Fix:
- New "flag_shipped_default_on" state in _FLAG_CATALOG, added
to flag_report() grouped output
- discourse_planner moved from default_off → default_on
- Test renamed to test_flag_report_classification_matches_actual_defaults,
enforces BOTH directions of the contract (catalog claim must
match DEFAULT_CONFIG value)
- New test test_flag_catalog_state_is_consistent_with_default_config
cross-checks every catalog entry against DEFAULT_CONFIG;
catches future drift before it lands
2. public_demo lane SHA shifted every commit
Each commit advances the showcase's generated_at_revision field
(git HEAD SHA). _strip_volatile in the lane runner was stripping
wall-clock and per-run paths but NOT generated_at_revision, so
the byte-equality case's details.sha256 changed with every commit
even when underlying demos produced identical content. That made
the pin a "did this run today" check rather than a "did the code
produce the right artifact" check — exactly the failure mode
the verifier was supposed to prevent.
Fix:
- Add generated_at_revision to _VOLATILE_KEYS in the public_demo
runner. Lane's invariant is "same code → same SHA," not
"same HEAD → same SHA"; HEAD belongs in the showcase output
(operators need it) but not in the lane's equality projection.
- Pin refreshed once to capture the now-commit-independent SHA;
subsequent commits won't shift it unless underlying demo content
actually changes.
After fix:
- Capability tests: 6/6 passing (was 4/5 with discourse_planner failing)
- Lane SHAs: 6/6 match pinned values; public_demo pin will now survive
routine code changes
- Smoke 67/67, cognition eval byte-identical 100/100/100/100
This is the single known pre-existing test failure cleaned up.
Six lanes (reviewer_registry, miner_loop_closure,
domain_contract_validation, fabrication_control_summary,
demo_composition, public_demo) now have CI-enforced SHA-256 pins.
A failing job means a lane's deterministic output changed without
an explicit ADR-tracked pin update.
- new scripts/verify_lane_shas.py: single source of truth
- PINNED_SHAS dict mapping lane_id → 64-char hex SHA
- LANE_SPECS tuple wiring each lane to its runner module + canonical
report path
- accepts_report_flag handles the fabrication_control runner's
different arg shape (--lane-dir not --report)
- verify_all() runs each lane in subprocess isolation (clean Python
state per lane — relevant for adapters that cache pack loads at
module import)
- --update flag refreshes pins after intentional ADR-tracked changes;
diff is the audit trail
- --json flag emits machine-readable report
- exits non-zero on any mismatch
- new .github/workflows/lane-shas.yml:
- triggers on push to main and pull_request to main
- concurrency group cancels in-progress runs on new commits
- Python 3.11 + pip-cached deps + editable install
- runs verify_lane_shas.py; emits JSON report on failure
- 12-minute timeout (lanes take ~30s in practice)
- new tests/test_lane_sha_verifier.py: cheap local-pytest pinning
- every LaneSpec has a corresponding PINNED_SHAS entry
- no orphan pins without a LaneSpec
- every pin is a 64-char hex SHA-256
- every runner module path exists on disk
- canonical report paths are under repo root
- all six expected lanes (ADR-0092/0093/0095/0096/0098/0099) covered;
ADR-0094 and ADR-0097 are schema/ratification only, intentionally
excluded from EXPECTED_LANES
- 6 tests run in <100ms — catches drift before CI
- evals/public_demo/results/v1_dev.json: refreshed to match the new
pin (21751aaf..) — earlier pin was generated under slightly different
runner argparse defaults; --update produced the canonical bytes
