The word "expert" in the previous status name implied raw-capability parity
with frontier LLMs on the same benchmark — which the gate does NOT verify.
What the gate actually verifies is CORE *claim-shape compliance*:
* signed digest (replay-reproducible from on-disk lane results)
* replay determinism (same inputs → byte-equal trace_hash)
* typed refusal (fabrication refused, not paraphrased)
* exact recall (no ANN, no cosine, no attention bottleneck)
* grounding-source provenance
These are claim shapes a transformer LLM cannot structurally produce
regardless of raw accuracy. A frontier LLM might score higher on the
same benchmark but cannot pass this contract.
Rename scope (semantics only, per ADR-0113):
status string "expert-demo" → "audit-passed"
predicate key predicates.expert_demo → predicates.audit_passed
reason key expert_demo_reason → audit_passed_reason
YAML key expert_demo_claims → audit_passed_claims
CLI command core demo expert → core demo audit-passed
output dir evals/expert_demos/ → evals/audit_passed/
artifact filenames expert_demo.{json,html} → audit_passed.{json,html}
HTML title CORE Expert-Demo: X → CORE Audit-Passed: X
Internal Python identifiers (module/file/function/class names like
`expert_demo.py`, `evaluate_expert_demo`, `ExpertDemoClaim`,
`expert_demo_claim_for`) are deliberately kept to minimize churn. ADR
file titles (ADR-0106..0112) preserved as historical record.
`expert` namespace reserved for ADR-0114+: an actual capability tier
above `audit-passed` backed by a public benchmark with a stated
threshold. ADR-0114 proposes the first such target — GSM8K-math —
laying out a falsifiable 7-phase arc (parser → solver → verifier →
stepped-realizer → eval lane → first `expert` ledger tier promotion).
Tests: 184 directly-affected tests green (140 capability/expert-demo
suite + 34 demo/audit-tour + 10 correction-cue). Smoke suite 67/67.

Closes ADR-0106 acceptance evidence:
- ExpertDemoClaim dataclass + additive expert_demo_claims block on
ReviewerRegistry (schema_version stays at 1; backward-compatible).
- New core/capability/expert_demo.py with derive_evidence_digest,
evaluate_expert_demo, collect_domain_lanes, materialise_lane_results.
- core/capability/reporting.py: replaces the cognition-lane-only
predicate (previous lines 418-433) with a domain-aware,
reviewer-signed gate; ledger rows now also carry
expert_demo_reason for operator legibility. Reviewer registry is
fail-closed: an unloadable registry yields zero claims, so a broken
registry never silently grants expert_demo=true.
- tests/test_expert_demo_contract.py covers all three ADR-0106
invariants: requires_signature, domain_aware, replay_byte_equality;
plus threshold + production-ledger-untouched gates. 12 new tests.
- tests/test_reviewer_registry.py extended with TestExpertDemoClaimsSchema
covering omitted block, valid parse, unknown signer rejection,
malformed digest rejection, duplicate domain rejection. 5 new tests.
- README index row + table preface updated to note expert_demo is
contract-gated. Frontier list trimmed (ADR-0106 has landed).
- ADR-0106 Status flipped Proposed -> Accepted.
No domain row's expert_demo field flips by this PR -- only the contract
changes. Promotion of any ratified domain requires a follow-up ADR
(ADR-0107 reserved for mathematics_logic) plus a signed claim.
Closes the load-bearing gap blocking every reasoning-capable claim
under ADR-0091: docs/reviewers.yaml was previously `reviewers: []` and
unparsed. Now schema-validated at v1, with a bootstrap shay-j entry
self-sealed via provenance.
- new core.capability.reviewers module: frozen Reviewer/ReviewerRegistry
dataclasses, strict load_reviewer_registry parser, ReviewerRegistryError
- enforces ADR-0092 schema rules: schema_version==1, no unknown
top-level keys, no unknown reviewer fields, role∈{primary,domain},
primary must claim ["*"], domain must NOT claim "*", review_scope
subset of {pack,proposal,chain,eval}, no duplicate reviewer_ids
- can_review(reviewer_id, domain_id, scope) helper implements
ADR-0092 rules 2-4 for downstream use by ADR-0093 validator
- docs/reviewers.yaml updated to v1 schema with shay-j bootstrap
- ledger_report() evidence_counts now exposes structured
reviewer_registry status (valid, schema_version, reviewer_count,
reviewer_ids, error) alongside the legacy reviewers_present bool
- new evals/reviewer_registry/ lane: 6 cases (2 positive + 4 negative)
covering empty-registry, wrong-version, domain-wildcard rejection,
and unknown-field rejection
- runner emits deterministic JSON report; two runs produce byte-identical
output (sha256 verified)
- 26 unit tests in tests/test_reviewer_registry.py
- capability ledger test extended to assert new reviewer_registry block
- smoke suite green (67/67); lane passes 6/6
The pre-existing test_flag_report_tracks_default_off_flags failure is
unrelated (discourse_planner flag default) and not introduced here.
