Forensic recovery: reconstruct PR_ARC_INVENTORY for #851-856, postmortem, salvage

[AdaWorldAPI]

Summary

Six consecutive merges (#851–#856) landed real, working code — the Rosetta convergence arc, the causality audit, a source_registry build-then-withdraw, the §12 substrate trace, the Base17 fold-ceiling measurement — while the session's own memory practice (PR_ARC_INVENTORY.md entries, GitHub review-thread replies) went completely dark. No handover was ever written for the run. This PR is a doc-only forensic recovery: it writes no production code, and rebuilds the missing record from merged diffs, commit history, PR bodies, and the GitHub review-comment API — never from inference.

• PR_ARC_INVENTORY.md — the six missing entries (Codebook licence regimes (one Release asset each) + PR-arc entry for merged #850 #851–Base17 fold ceiling measured (dimensional, not the fold) + GOLDEN_STEP proven a relabel + #855 review fixes #856), prepended, format-conformant, with UNRECONSTRUCTED markers wherever the record doesn't support a claim (e.g. Rosetta convergence arc + rung-stratified standing wave + anti-eigenvalue guards (36 commits) #852's PR-body description drift: claims 55 files/+12,207, merged diff is 50 files/+7,591).
• .claude/handovers/2026-07-27-2114-arc-841-856-postmortem.md — answers where the ledger habit broke (the first commit of Rosetta convergence arc + rung-stratified standing wave + anti-eigenvalue guards (36 commits) #852, immediately after Codebook licence regimes (one Release asset each) + PR-arc entry for merged #850 #851 correctly wrote D-SCI-1 findings: anaphora window is a type boundary + the gateway-text projection hinge (German codebook generator) #850's entry), why (editing the board-hygiene rule's wording was mistaken for satisfying it — the documentation-process twin of the vacuous-assertion defect the same session promoted to a P0 rule the same day, about unrelated code), a measured restart cost (at least 3 architectural directions built then withdrawn across Causality audit: type the causal edge, declare kernel effects — and withdraw the source registry as a falsified design #854–Substrate trace + palette256/[a,b] canon measured: furnace amortization validated, FisherZ certifies 0.9998, zero-copy AdjacencyBatch, doc truthfulness #855), which Substrate trace + palette256/[a,b] canon measured: furnace amortization validated, FisherZ certifies 0.9998, zero-copy AdjacencyBatch, doc truthfulness #855 CodeRabbit findings were context-loss vs. ordinary error, a proposed merge-time guard with both falsifier halves, and an honest both-sides argument on whether Rosetta convergence arc + rung-stratified standing wave + anti-eigenvalue guards (36 commits) #852's 44-commit autonomous run was the cause or a success.
• .claude/knowledge/parked-designs-841-856.md — salvages the source_registry withdrawal (correct design, blocked on a still-missing evidence-event identity type — the exact condition that unblocks it is stated), primer §13→§15 (superseded, not deleted), and identifies the CLAM/HHTL ↔ WordNet centroid-ancestry alignment probe as the one item the whole D-SCI-1 Phases 1+2: right-corner delayed commitment + PROIEL witness-gated construction licenses #849–Base17 fold ceiling measured (dimensional, not the fold) + GOLDEN_STEP proven a relabel + #855 review fixes #856 arc was scaffolding toward (WordNet rail rebuild, licence-cleared lanes, an isolated Base17-ceiling confound) and never got to run — with the exact rebuild condition (4⁴ hierarchical codebook, not 16×16) that unblocks it.
• ISSUES.md — every never-answered review/issue comment found across D-SCI-1 Phases 1+2: right-corner delayed commitment + PROIEL witness-gated construction licenses #849–Base17 fold ceiling measured (dimensional, not the fold) + GOLDEN_STEP proven a relabel + #855 review fixes #856, classified fixed-forward-but-never-replied-to (Rosetta convergence arc + rung-stratified standing wave + anti-eigenvalue guards (36 commits) #852, 20 threads) vs. genuinely still-open (Codebook licence regimes (one Release asset each) + PR-arc entry for merged #850 #851's 2 licensing critiques, Causality audit + generator restore + three unfalsifiable assertions repaired #853's 3 threads, Base17 fold ceiling measured (dimensional, not the fold) + GOLDEN_STEP proven a relabel + #855 review fixes #856's 3 threads — including a live, unresolved codex rebuttal of Base17 fold ceiling measured (dimensional, not the fold) + GOLDEN_STEP proven a relabel + #855 review fixes #856's own headline finding) vs. a clean counter-example (Substrate trace + palette256/[a,b] canon measured: furnace amortization validated, FisherZ certifies 0.9998, zero-copy AdjacencyBatch, doc truthfulness #855's 11 post-merge threads, all closed out one PR later).
• EPIPHANIES.md — E-SHIPPING-CAN-OUTRUN-ITS-OWN-RECORD-1, naming the failure mode: code quality never degraded: the record of the code did, and nothing about the shipped work's quality signaled the gap from inside the session producing it.

Test plan

• No production code touched — verified: only .claude/board/*.md (pure prepends, 0 deletions confirmed via git diff --stat), plus two new files under .claude/handovers/ and .claude/knowledge/.
• No past board entry edited — only prepended (git diff shows 318 insertions, 0 deletions across the three modified board files).
• Every claim traces to a diff, commit hash, PR body, or GitHub review comment fetched live via the API on 2026-07-27 — no claim from inference; UNRECONSTRUCTED used where the record doesn't support one.
• The CLAM/HHTL ↔ WordNet probe is not silently re-parked a third time — it's named with its exact blocking condition and exact falsifier in parked-designs-841-856.md.

Poem

I nibbled the ledger back into the light,
Filed every thread that escaped from sight.
Six arcs now rest in their proper row,
With gates for the records we ought to show.
Deferred dreams wait beneath the moon—
D-RCC-5 may sprout soon! 🐇
