gov: post-merge board-hygiene tail for PR #372#374
Merged
Conversation
Per CLAUDE.md Mandatory Board-Hygiene Rule, post-merge updates for the canonical board state. All 5 files updated: PR_ARC_INVENTORY.md: PREPEND PR #372 entry (Added / Locked / Deferred / Docs / Confidence sections per format) above #366. LATEST_STATE.md: PREPEND row for PR #372 in Recently Shipped table; update Last-updated metadata line with PR #372 summary and the three major findings (dual CausalEdge64, p64 drift origin, three-zone hot path); add Contract Inventory section for the dual CausalEdge64 types. EPIPHANIES.md: PREPEND E-META-7 dated 2026-05-14 covering the three coupled findings — dual CausalEdge64 types, p64 drift origin pinpointed at convergence.rs:18-22 #[allow(unused_imports)] annotation, three-zone hot-path mental model. TYPE_DUPLICATION_MAP.md: APPEND section #13 documenting CausalEdge64 as 2 distinct types in workspace (NOT a candidate for direct dedup; they represent different cognitive operations). Includes the 8-channel to SPO transcoding mapping (Option R-3) and the drift-origin reference. STATUS_BOARD.md: APPEND causaledge64-mailbox-rename-soa-v1 plan section with 13 D-CE64-MB-* / D-SPRINT-10-* spec-shipped rows + 15 sprint-11 implementation rows (all Queued, with per-row blockers cited) + 4 user-ratification gates (CSI-1 + OQ-1/3/5) + 6 reunification track items (D-REUNIFY-1..6) tracking the sprint-12+ Think carrier struct unification arc. D-REUNIFY-1 (acknowledge dual CausalEdge64 in board files) is marked Shipped by this very commit. https://claude.ai/code/session_01UwJuKqP828qyX1VkLgGJFS

This table says it is copying the Option R-3 mapping from .claude/knowledge/causal-edge-64-synergies-and-pr-trajectory.md §6.3, but that source maps BECOMES / GROUNDS / RELATES to InferenceType::Synthesis, not Abduction. If a future sprint-12 transcoder is implemented from this summary, GROUNDS edges would be committed with a different inference type than the canonical design, so please either update this row to Synthesis or change the cited source too.
Useful? React with 👍 / 👎.
…ption R-3 mapping PR #374 review (chatgpt-codex-connector P2 catch): TYPE_DUPLICATION_MAP §13 mapped GROUNDS → InferenceType::Abduction, but the cited canonical source (.claude/knowledge/causal-edge-64-synergies-and-pr-trajectory.md §6.3 Option R-3) groups BECOMES / GROUNDS / RELATES → InferenceType::Synthesis. If a future sprint-12 transcoder were implemented from this summary, GROUNDS edges would commit with a different InferenceType than the canonical design — silent drift across two derivative references. Fix: change GROUNDS row to Synthesis matching the canonical source. Added an inline note that the semantic question (Synthesis vs Abduction for "foundational basis = abductive justification") is an open design question for the sprint-12+ transcoder spec — preserving the bot's catch as architectural future work rather than just hiding it. No other rows audited as drifted: CAUSES (Deduction), SUPPORTS (Revision+), REFINES (Abduction), ABSTRACTS (Induction), RELATES (Synthesis), CONTRADICTS (Revision-), BECOMES (Synthesis) all match the synergies doc. https://claude.ai/code/session_01UwJuKqP828qyX1VkLgGJFS

Summary
Post-merge governance for PR #372 (sprint-10 spec corpus). Per CLAUDE.md Mandatory Board-Hygiene Rule, a merged PR without board updates is incomplete. The PR #372 body explicitly parked these for post-merge so they reflect the actual merged outcome.
One commit (
2d0121c), 5 files changed, +193 / -1, all.md(board files +docs/TYPE_DUPLICATION_MAP.md).What changed
.claude/board/PR_ARC_INVENTORY.md.claude/board/LATEST_STATE.md.claude/board/EPIPHANIES.mdconvergence.rs:18-22 #[allow(unused_imports)]annotation, three-zone hot-path mental modeldocs/TYPE_DUPLICATION_MAP.md.claude/board/STATUS_BOARD.mdcausaledge64-mailbox-rename-soa-v1plan section with 13 spec-shipped rows + 15 sprint-11 Queued impl rows (per-row blockers cited) + 4 user-ratification gates + 6 reunification track itemsWhy a separate PR
PR #372 was governance-only spec content. This is governance-only board updates. Splitting them keeps each PR's review surface bounded and lets PR #372's Confidence line reference this hygiene tail explicitly once merged.
Test plan
This is a governance-only PR (board file updates; no code; no tests). Review focus:
.rsfiles changed (git diff --name-only origin/main..HEAD | grep '\.rs$'returns empty)After merge, the canonical board state matches reality for any session that reads
