Closes the documentation audit. All four lower-priority surfaces from
the earlier scan now reflect the post-ADR-0110 reality.
New:
- docs/sessions/SESSION-2026-05-22-contract-layer-arc.md: full
narrative of the ADR-0103 -> ADR-0110 arc, including the
refused/amended/succeeded narrative, infrastructure bridges, and
ledger state at session close. Pairs with the 2026-05-21
articulation-arc session log.
Extended (additive, no rewrites):
- docs/runtime_contracts.md: new 'Expert-Demo Promotion Contract
(ADR-0106 + ADR-0109)' section. Surfaces ledger_report() shape,
reviewer-yaml schema, lane-shape registry, replay invariant,
fail-closed registry behavior, and trust boundary.
- docs/eval_methodology.md: new 'Lane-shape registry (ADR-0109)'
section. Documents what to do when adding a new eval lane:
pick a shape or amend ADR-0109. Notes the holdout-runner gating
(cases_plaintext.jsonl vs sealed). Header bumped to 2026-05-22.
- docs/Whitepaper.md: new section XIII 'Evidence-Governed Domain
Layer' between XII (Forward Semantic Control) and the
Extensions/closing. Narrates the contract chain at the
philosophical / external-reader level. The original §XIII
becomes §XIV.
- docs/Yellowpaper.md: new section XII 'Ratification Contract
(ADR-0091 + ADR-0106 + ADR-0109)'. Formal specification of the
nine predicates, the promotion predicate (with explicit logical
form), the digest function, and the lane-shape registry table.
The original §XII becomes §XIII.
No code, no tests, no contract changes.
