Gate A1 and related cognition-path changes shifted the showcase
determinism fingerprint (86db25b6…) while the lane pin still reflected
the pre-drift artifact (e323adb3…). Re-pin to the CI-verified SHA
2895df08… and refresh v1_dev.json + CLAIMS.md.
Hermetic demo hygiene: use no_load_state for register-tour, learning-
loop, and multi-hop showcase adapters, and isolate CORE_ENGINE_STATE_DIR
in the public_demo lane runner so local engine_state/ pollution cannot
affect eval output or wall-clock.
* 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.

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.
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.
Second worked promotion exercising the ADR-0106 + ADR-0109 contract
on a domain distinct from mathematics_logic. No contract change.
Evidence:
- foundational_physics_ood: accuracy=1.0 (117/117 public, 39/39 holdout)
- inference_closure: all_pass_rate=1.0 (shared with math, distinct digest via domain_id)
- fabrication_control: refused=n, fabricated=0 across all classes (shared)
Signed claim digest: a104cad136f3219df05dc7ce6a78437c02f7b5827cd3cdce568db3acda6a43ed
Bridge landed: cases_plaintext.jsonl dev-mode fallback for
foundational_physics_ood (matches ADR-0105 convention; analogous to the
math/inference bridges in ADR-0110). One small file, not a contract change.
Tests:
- tests/test_adr_0111_physics_expert_demo.py — 4 invariants, 6 cases
- tests/test_adr_0110_math_expert_demo.py — relaxed "only math promoted"
to "math stays promoted" (load-bearing for ADR-0110 is persistence)
- tests/test_capability_reports.py — physics row now expert-demo
Retires the "first promotion was math-specific" objection: the bridges
ADR-0110 landed were correctly scoped, and the contract holds across
two distinct domains using shared lane infrastructure with distinct
digests.

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
Local verifier: 6/6 lanes match pinned SHAs. Smoke 67/67. Lane SHAs:

Single 30-second artifact composing four CORE invariants
(determinism, honest unknown, reviewed learning, multi-hop with
trace) by delegating to existing DemoCommand adapters. **No new
mechanism** — every claim is backed by an already-shipped,
separately-tested adapter. Closes the 8-ADR scale-up slate.
- new core/demos/learning_loop_adapter.py: LearningLoopDemo wraps
ADR-0056 reviewed-teaching loop; _strip_volatile_paths drops
transient temp-dir paths from raw before serialization so the
adapter's report_sha256 is content-stable across runs
- new core/demos/showcase_adapters.py:
- FabricationControlPublicDemo: re-runs ADR-0096 public split,
produces 3 claims (refusal_recall_meets_threshold,
fabrication_rate_below_threshold, trace_evidence_present)
- MultiHopTraceDemo: runs 'Does light reveal truth?' with
transitive_surface=True + composed_surface=True against
cognition pack; surfaces a 3-hop walk light→truth→knowledge→
evidence; produces 3 claims (grounded_answer, depth_two_or_more,
walk_evidence_present)
- new core/demos/showcase.py: run_showcase() composes 4 scenes,
emits showcase.json + per-scene artifacts; render_html() produces
presentation-only static HTML with no JS injection vector;
ShowcaseScene dataclass; MAX_RUNTIME_SECONDS=30 hard ceiling
with DemoContractError if exceeded
- CLI: 'showcase' added to demo target choices; --output-dir flag
added; cmd_demo dispatch branch writes showcase.json + showcase.html
- new evals/public_demo/ lane with 4 cases:
- all_claims_supported (each scene + composite)
- determinism_run_to_run_byte_equality (two runs identical after
stripping volatile keys: total_runtime_ms, json_path,
transient_corpus)
- runtime_under_budget (≤30s)
- pure_composition_no_new_mechanism (grep gate over showcase
imports — must come from core/chat/generate/language_packs/
teaching/evals or allowed stdlib only)
- lane is itself byte-identical across runs (sha256 5707db8efc6a..);
runtime case omits exact runtime_ms (it varies near bucket
boundaries) but still asserts ≤ budget
- 8 unit tests with module-scoped fixture (showcase runs once,
~13s total) covering payload shape, scene order, runtime budget,
HTML render absence of <script>, and the pure-composition import
gate independently of the lane
- ADR-0099 measured: total_runtime_ms ~12.8s, well under 30s budget
- smoke 67/67, cognition eval byte-identical 100/100/100/100;
all 6 ADR-0092..0099 lanes byte-identical:
reviewer_registry 681a2aab..
