From 41aea0ab530af4faf5318b6bd46eac34a9a894a7 Mon Sep 17 00:00:00 2001 From: Aaron Stainback Date: Thu, 14 May 2026 16:29:35 -0400 Subject: [PATCH] =?UTF-8?q?shard(tick):=202026Z=20=E2=80=94=20BACKLOG.md?= =?UTF-8?q?=20generated-index=20drift=20cleanup=20(B-0517/B-0518/B-0519)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tick output: - PR #3226 (chore(backlog) regen) — fixes the non-required `check docs/BACKLOG.md generated-index drift` warning that #3221 surfaced. Three on-disk rows (B-0517/B-0518/B-0519) were missing from the auto-generated index. Pure regen; no per-row file changes. - This shard. Prior-tick PRs: - #3221 (chore(b-0502) launchd plist) — MERGED as eb81404. - #3222 (shard 2010Z) — still wait-ci, autoMerge armed. Branch-state contamination this tick — 2 incidents, both worked around: - After my push, gh pr create said "not on any branch" — HEAD detached at origin/main (parallel Otto's checkout). Fixed: re-checkout my branch. - Second gh pr create: HEAD now on fix/b-0518-sharpen-... (different Otto's branch). Fixed: gh pr create --head explicit flag. New substrate-honest defenses for multi-Otto-one-checkout topology: - git branch --show-current immediately before git commit (primary catch) - gh pr create --head explicit flag (prevents poisoned current-branch) Cron sentinel 12fb713e armed; recurring.
