Board hygiene owed by #974 and #975

[AdaWorldAPI]

Board hygiene owed by two merged PRs. This PR's entire content is hygiene — no type, plan, deliverable, epiphany, or code — so per CLAUDE.md § Termination clause it generates none of the merged-PR row's obligations: no arc entry and no LATEST_STATE update of its own. It is discharged by the entries it writes.

Why late

#974 merged 2026-08-20 and its obligation was missed at the time. Verified before writing: PR_ARC_INVENTORY.md and LATEST_STATE.md each had 0 mentions of it. It shipped types (dismech_evidence), so the Termination clause does not exempt it. The entry records that it is late rather than backdating it.

#975 merged 2026-08-21 at 04:18.

PR_ARC_INVENTORY.md — two prepended entries

#974 — the dismech_evidence module surface, and three rulings worth a future session's read:

• SOURCE-SIDE ONLY, deliberately does not reference CausalEdge64. The durable causal overlay must not become a pile of hot reasoning registers; DismechTopology → CE64 bits 59..60 happens at hydration, in the consumer.
• Every parse fails closed. UNKNOWN is a value the corpus asserts 408 times, so minting it from a parse failure would forge an assertion the source never made.
• Citation identity never derives from the title — the falsifier that matters for an LLM-generated corpus.

It also carries an explicit Superseded by #975 line for the one doc claim that did not survive, rather than leaving the arc reading as if it had.

#975 — the three findings, the two codex P1s (both CONFIRMED, both fixed pre-merge), and the two rules the session actually paid for:

• Absent ≠ unwired, and the remedies are opposite. Absent ⇒ build the organs. Unwired ⇒ build nothing, close the seam. The retracted AriGraph claim recommended the expensive one.
• A measurement a committed parser can make must not be made by an ad-hoc script. The line-scanner was wrong by 23 edges; the committed parser is right and runs in under a second.

LATEST_STATE.md

#974's heading becomes a merged-PR entry; #975 is added above it. The AriGraph correction is included as a standing warning, not just history: crates/lance-graph/src/graph/arigraph/ is 15 shipped modules (ppr / bm25 / rrf / community / markov_soa / episodic / witness_corpus / retrieval / …) and must not be rebuilt under a new name by a future session that greps for a function spelling and concludes absence.

Also carried forward as the one open blocker: the third bucket for the 1,466 label-only edges and the 92 contradictory ones — an operator decision that gates any gold set.

Gates

Board files only; no code touched. lance-graph-contract was 1180/1180 at the merged head.
