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.
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.
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..
miner_loop_closure 9f071733..
domain_contract_validation f9c06cde..
fabrication_control sum 01e1b6b7..
