…-close) → #811; fix #809 Codex P1 timestamp-filename align (1) PR #806 was unexpectedly closed by GitHub at 06:16:23Z (1s after #808 merge), likely due to force-push-after-rebase triggering "no commits ahead of base" computation despite 476 lines of unique substrate remaining on the branch. Recovered by opening PR #811 against the same branch. (2) PR #809 had Codex P1 — shard filename 0613Z.md vs row timestamp 06:12:50Z misalignment. Fixed: timestamp updated to 06:13:00Z. Thread resolved. New micro-classes: - force-push-triggers-pr-auto-close (mitigation: avoid rebasing PRs mid-flight) - shard-filename-vs-timestamp-misalignment (mitigation: mechanical guard comparing HHMM vs HH:MM) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…#814) + #811 Copilot fixes (#816) (1) PR #812 (0619Z) + #813 (0623Z) + #814 (0625Z) all squash-merged. (2) PR #811 had 2 Copilot threads — both REAL_DEFECT: - B-0098: \b in grep -oE non-portable (POSIX ERE issue); replaced with -w whole-word match. - B-0099: @me placeholder ambiguous; replaced with <gh-login> + clarifying note. Both threads resolved. Merge cascade observation: 3 tick-history PRs landed within seconds once merge-eligibility cleared. Composes with the auto-merge-arm pattern.
