First concrete domain claim under ADR-0091's Domain Pack Contract v1.
en_mathematics_logic_v1 is now formally ratified as reasoning-capable
in the capability ledger: 9/9 ADR-0091 predicates pass.
ADR-0097 §"No code changes outside pack artifacts and corpus" relaxed
to include two latent bug fixes that ADR-0093's predicate enforcement
just exposed:
1. language_packs/schema.py: LanguageRole enum widened to include
DOMAIN_SEED. Three in-tree packs (en_mathematics_logic_v1,
en_physics_v1, en_systems_software_v1) have declared role="domain_seed"
since landing but the enum was never updated; load_pack() always
raised on them. ADR-0093's P1 predicate exposed the mismatch.
2. core/capability/domain_contract_predicates.py: P2 (gloss checksum)
was reading manifest["checksums"]["glosses_sha256"]; the canonical
in-tree location is manifest["glosses_checksum"] (top-level). Fixed
to prefer the canonical key and fall back to the nested form for
forward compatibility.
ADR-0097 manifest additions to en_mathematics_logic_v1:
- domain_contract_version: 1
- domain_id: "mathematics_logic"
- axioms: null (rules in v1 — pack proves reasoning via chain
composition, not declarative axioms)
- rules: null
- teaching_chains: ["mathematics_logic_chains_v1"]
- eval_lanes: three lanes with dev/public/holdout (elementary_mathematics_ood,
inference_closure, fabrication_control)
- reviewers: ["shay-j"] (resolved via ADR-0092 registry)
- known_gaps: [] (all math/logic gaps in docs/gaps.md were [x])
- provenance: "adr-0097:reviewed:2026-05-21"
Verified evidence:
- core capability domain-contract --pack-id en_mathematics_logic_v1
→ all_passed=True (P1-P9 all pass)
- core capability ledger → mathematics_logic row shows
status=reasoning-capable, predicates.reasoning_capable=True,
predicates.expert_demo=False, open_gaps=[],
operator_chain_coverage all ready=True (8 chains each),
intent_shapes_present=5
- 14 ADR-0097 invariant tests in
test_adr_0097_mathematics_logic_ratification.py pin
status/provenance/expert-demo-gate/contract shape
Two pre-existing tests updated for the new CLI default
(predicate-running, non-zero on missing contract):
- test_capability_domain_contract_json_absent_contract_is_noop now
uses --structural-only to assert legacy parse-only shape
- test_cli_returns_nonzero_on_missing_contract switched its fixture
pack from en_mathematics_logic_v1 (now has a contract) to
en_core_cognition_v1 (no contract)
The pre-existing test_flag_report_tracks_default_off_flags failure
(discourse_planner flag default mismatch, seen since ADR-0092) is
unchanged and unrelated.
