…+ branch-contamination untangle Tick output: - PR #3221 (chore(b-0502)): new .gemini/launchd/com.zeta.backlog-ready-notifier.plist + AUTONOMOUS-LOOP.md + tools/bg/README.md + B-0441/B-0502 row updates. Closes B-0441 AC #2 ("Runs under existing launchd / cron infrastructure"). Auto-merge armed. - This shard. Branch-state contamination caught + untangled mid-tick: - Local main had orphan 1856Z shard (9fa74ac) — work already on main via #3187. Reset. - During B-0502 work, my commit landed on a different Otto's branch (the exact B-0519 pattern). Untangled via reset + cherry-pick to the correct otto/b0502-... branch. - ZETA_EXPECTED_BRANCH hook didn't catch the wrong-branch commit (env-var didn't persist across separate Bash-tool calls). Worth a follow-up row. Substrate-or-it-didn't-happen check: - PR #3221 = B-0502 substrate (will be on main when CI clears) - This shard = the tick record (substrate-honest visibility of the contamination untangle so future-Otto sees the field-test result) Cron sentinel 12fb713e armed at session start; one entry, recurring.

Pull request overview
This PR adds a single tick log file recording the autonomous-loop shard at 2026-05-14T20:10Z. Substantive work landed in PR #3221; this file documents the tick and the first successful field-test of the B-0519 branch-contamination untangle procedure.
Changes:
- Adds tick history file under per-tick path discipline
- Records branch-state contamination incident and untangle steps
- Notes secondary
ZETA_EXPECTED_BRANCHhook failure for follow-up
… shard Two MD032/blanks-around-lists violations: prose headers before bullet and numbered lists lacked the required blank separator. Co-Authored-By: Claude <noreply@anthropic.com>

…/B-0518/B-0519) (#3227) 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 <my-branch> 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 <branch> explicit flag (prevents poisoned current-branch) Cron sentinel 12fb713e armed; recurring.

…6 defenses) (#3231) * shard(tick): 2030Z — B-0519 RCA additive update (Pattern 5 + Pattern 6 defenses) Tick output: - PR #3228 (chore(b-0519) additive update): adds Pattern 5 + Pattern 6 contamination patterns + new cheap defenses (git branch --show-current before commit + gh pr create --head explicit ref) + caveat on ZETA_EXPECTED_BRANCH env-var hook reliability. Pure additive update; no per-row metadata changes. Auto-merge armed. - This shard.

Observed but not yet RCA'd: working-tree files from a different Otto's branch surviving `git checkout -f origin/main`. Caught + corrected via git checkout origin/main -- <leaked-file>. Repro needed before RCA.

Renames the heading to "Session PR tally (2 merged, 3 wait-ci)" so future-Otto session archaeology reads unambiguously.

Summary
Tick 2026-05-14T20:10Z autonomous-loop shard. Substantive work landed via #3221 (B-0502: launchd plist for
backlog-ready-notifier, closes B-0441 AC #2). This shard records the tick + the first field-test of the B-0519 branch-state contamination untangle procedure.What landed
Branch-state contamination, untangled
Between
git checkout -b otto/b0502-...andgit commit, another Otto process in the same physical repo checked outshard/tick-2018Z-39-candidate-triage-otto-cli-2026-05-14. My HEAD moved invisibly; the commit landed on the wrong branch on top of the other Otto's work.The B-0519 untangle procedure WORKED first-try:
git reset --hard 5bd5697on the contaminated branch (restored the other Otto's tip; no work destroyed)git checkout otto/b0502-...(intended branch, still at origin/main)git cherry-pick dab036d→ new clean commit73e35dbon the right branchSecondary failure worth a follow-up row: the
ZETA_EXPECTED_BRANCHPreToolUsehook didn't catch the wrong-branch commit because the env var was set in one Bash-tool call but didn't persist to the call that executedgit commit. Primary catch should begit branch --show-currentimmediately beforegit commit; the env-var hook is defense-in-depth, not primary.Cron
