…5 → 52) PR #4461 review threads from codex + copilot caught two factual errors: 1. Time-gap from prior tick: claimed ~33h but actual is ~6h (2026-05-20T18:07Z → 2026-05-21T00:08Z). I conflated my initial stale read of "last shard at 2026-05-19/1626Z" with the actual latest-on-main 2026-05-20/1807Z shard. 2. Stash count inconsistency: table row said "5 stashes" while intro + empirical-anchor narrative said "52 stashes". Reconciled to 52 (actual `git stash list | wc -l` result). Both threads are verify-before-fix true positives; no FP class. Co-Authored-By: Claude <noreply@anthropic.com>

Pull request overview
Corrects two factual inaccuracies in the already-merged hygiene-history tick shard 2026/05/21/0059Z, aligning the narrative and the observation table with the verified timeline and git stash count.
Changes:
- Fixes the cold-boot time-gap estimate from
~33hto~6h(1807Z → 0008Z next day). - Fixes the contested-root stash count from
5 stashesto52 stashesin the observations table.

…criminator generalizes (#4472) Follow-up to PR #4461 + PR #4468 (0059Z cold-boot + corrections). Verifies the orphaned `otto/2012z-...` branch carry-forward against current origin/main: 4 of 5 commits' substrate already rescued via peer agents. The HC-8 NCI commit (f0abf3e) was rescued by PR #4205 between 2026-05-18 (orphan creation) and 2026-05-21 (this cold-boot). Generalizes the substrate-drift discriminator from backlog-row scope (in .claude/rules/backlog-item-start-gate.md step 0) to orphaned-branch scope: before assuming orphaned commits need re-landing, check substrate against origin/main via per-file diff. 0 lines = fully rescued; 20-50 lines = partial drift cell-by-cell; hundreds = genuine deltas. Supersedes the 0059Z carry-forward as overestimated. Co-authored-by: Claude <noreply@anthropic.com>

Summary
PR #4461 auto-merged before this fix landed; the merged-on-main shard contains two factual errors caught by codex + copilot reviews:
~33h→~6h(2026-05-20T18:07Z → 2026-05-21T00:08Z). I conflated stale on-disk shard listing with actual latest-on-main shard5 stasheswhile intro + narrative said52 stashes. Reconciled to52(the actualgit stash list | wc -lresult)Supersedes #4465 which had a rebase conflict (its head branch carried the now-squash-merged original commit as well).
