From de3a9a88ea45127c77f589650f6e2ae2c682ea0a Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 12 Aug 2026 06:50:19 +0000 Subject: [PATCH 1/3] board: record merged PR #926 (arc entry + LATEST_STATE) Post-merge board hygiene mandated by CLAUDE.md's Mandatory Board-Hygiene Rule: a merged PR requires a PR_ARC_INVENTORY prepend + a LATEST_STATE table entry, and both can only be written after the merge lands. The arc entry records what #926 established (the 90.9-94.3% spine, the 12-byte 6x(8:8) L4 carrier at 0.07 Pa RMSE, the Fisher-z rank/tail-vs-level demarcation), what it explicitly does NOT claim (CT-F14 NO-VERDICT, domino.rs is a fixed tridiagonal kernel not a moderator model, theta_e is a proxy not a budget), and the two methodological rules worth carrying forward: * R2 is structurally near-blind to encoder bias -- var() at 11 sites hid a +92.76 Pa offset, and "lossless" was inferred from the one statistic that could not detect the loss. Report RMSE and mean bias in the physical unit beside every R2. * The dominant defect class is PROPAGATION, not judgment. All five documentation defects were one claim corrected in one home and left standing in another -- prose vs artifact, body vs heading, code vs JSON, report vs PR description. When correcting a claim, grep for its twins. Per the rule's own termination clause this commit is hygiene-only and generates no further obligations: it adds no type, plan, deliverable, epiphany or code, and is discharged by the entries it writes.

From 0f9e6bcde58ef86867b16a7c814ee1a92e0db22c Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 12 Aug 2026 06:52:32 +0000 Subject: [PATCH 2/3] board: Fisher-z ring-mean ratio is 4.7x, not 5x -- in all four homes Caught by verifying this PR's OWN board entry against the committed JSONs before landing it: 18.07 / 3.84 = 4.71, not 5. A 6% rounding in the FAVOURABLE direction, one commit away from being frozen into an append-only record. Fixed in all four places the claim lives -- PR_ARC_INVENTORY, LATEST_STATE, EPIPHANIES, and COMET_TAIL_REPORT SS6.1 -- because the arc's dominant defect class is a claim corrected in one home and left standing in another, and fixing three of four would have reproduced it exactly. Nine of ten figures in the new entry verified exactly against the JSONs (0.9434 / 0.9090 spine, 0.07 Pa carveD RMSE delta, +1.59 Pa carveD bias, +92.76 Pa carveA bias, 0.9129 carveA R2, 0.684 CT-F14, 8.3x storm-tail, 139x L4x penalty). This was the tenth. Makes the PR mixed (hygiene + one correction) rather than hygiene-only, so the correction is recorded as a dated line inside the #926 arc entry it corrects, per the append-only convention -- not as a separate entry.

After merge, preserve the historical entry unchanged except for permitted Status and Confidence updates." The EPIPHANIES entry carrying "5x WORSE" merged with #926. My previous commit changed that number to 4.7x IN PLACE and UNMARKED -- which is history rewriting, not correction, and is the one thing an append-only ledger exists to prevent. Restored verbatim. The correction still stands where it belongs: in the newly-prepended #926 arc entry, which now also records that the merged line is deliberately frozen and why. A newest-first ledger is read from the top, so a frozen historical line is not a trap -- it is the audit trail. COMET_TAIL_REPORT.md keeps the 4.7x fix; it is not a board file and carries no append-only constraint. Noting the shape without excusing it: I made an unmarked edit to a frozen ledger inside a commit whose subject was propagation discipline. The rule I was citing is the rule I broke.
