board: arc entries for #1074 + #1075, batched (hygiene-only — chain terminates here)

[AdaWorldAPI]

Discharges the merged-PR board obligation for both PRs: PR_ARC_INVENTORY prepends + the LATEST_STATE table row.

Batched deliberately. Each entry was owed by its own PR's commits — that's my miss, and CLAUDE.md names the retroactive-cleanup pattern as the anti-pattern. Since it's retroactive either way now, one combined entry beats two separate cleanups, and the arc reads as one coherent event rather than two half-events.

Per the termination clause this PR is hygiene-only and generates NO further obligations — no arc entry, no LATEST_STATE update for itself. The chain stops here.

What the entries record that a future session cannot re-derive

ISS-KANBAN-PLAN-EXIT-HAS-NO-NAMED-ROUTE — CLOSED. Evaluation's successors are [Commit, Plan, Prune]; advance() took the first non-Prune (always Commit), veto() took Prune, and nothing produced Plan. The documented revision exit had legal-edge status and no route.

Two items OPEN ON MAIN, flagged rather than silently fixed:

1. F-MEP-0b still reads "covariance or precision." jc::ewa_sandwich_3d is explicit — "world-space covariance matrices Σ ∈ ℝ³ˣ³ … pushed forward to image-space", M_k = sqrt(Σ_k), consumer ndarray::hpc::splat3d. Precision would be a new quantity borrowing the algebra, not reuse of the EWA operator. The real open question is the bounded monotone trust → step-transform mapping.
2. Σ → TrustTexture → GateDecision in §0b/§4 conflicts with EWA scoped as attention/tension geometry.

Both misdirect W1 before it runs. Neither is a defect in the merged text's own terms — which is exactly why they need a follow-up PR rather than a session note that evaporates.

Two prior-art corrections, both against earlier claims of mine:

• Stamp::disjoint is canonical for S4 pooling under KNOWN overlap; the PR Causality audit: type the causal edge, declare kernel effects — and withdraw the source registry as a falsified design #854 ruling is canonical for evidential independence not being established (event identity ≠ evidential-base membership ≠ source dependence; Stamp is lossy at 1 << (id % 64); causal_audit.rs:346 leaves independent_strength None for want of a dependence model). FusionReceipt::shared_roots is therefore CONJECTURE, not duplication.
• stance_panel is not H₃ — four non-destructive readings of an existing state, not the construction of a larger horizon. The Grail survives and is unbuilt.

The next two plans and their gating, including the H₃ wording correction: parallax earns the first buyer for H₃; it does not define H₃.

📝 Walkthrough

Walkthrough

The PR adds append-only board records for merged PRs #1074 and #1075. The records document the epistemic triptych, Plan routing, EWA trust propagation, corrections, open issues, and queued work.

Changes

Board arc documentation

Layer / File(s)	Summary
Merged contract and board state record .claude/board/PR_ARC_INVENTORY.md, .claude/board/LATEST_STATE.md	Documents the fusion, counterfactual, and revision contract; revision routing to Plan; evidence-root semantics; validation status; corrections; and follow-up work.
EWA trust-propagation plan .claude/board/PR_ARC_INVENTORY.md	Documents the EWA candidate operator, preregistered statistical gates, graph-internal evidence restrictions, methodological defects, scope corrections, and open issues.

Poem

A rabbit records the board tonight

New arcs are tucked in neat and right
Fusion hops, revision follows
EWA maps its trust-filled hollows
Open questions wait in sight
And queued work springs toward the light
