Summary

1h 03m cascade from 1531Z → 1634Z. PRs #3897 (B-0462), #3898 (1535Z shard), #3900 (1547Z shard), #3903 (1610Z + path-depth table) all merged. PR #3906 (fix-1547z-on-main) auto-merging cleanly.

Substrate-honest lessons documented

  1. Auto-merge race — sub-case 5 of claim-acquire saturation-ceiling: fix-pushes to a branch that already has auto-merge armed can lose to the original commit
  2. Lint check propagation — broken paths on `main` propagate as new errors to subsequent PRs via the audit's all-shards scan
  3. Path-depth reference table (landed in 1610Z.md via PR shard(tick): 2026-05-16T16:10Z — fix relative-path depth in 1535Z + 1547Z (CI lint catch); path-depth reference table #3903) is the durable substrate fix; future tick-authoring across all 3 Otto surfaces reads it at cold-boot

Persistent contamination class — empirical anchor

`git branch --show-current` caught HEAD-shift to 5 different peer-Otto branches across 5 consecutive cron fires. Zero commits landed on peer branches. The branch-discipline rule (not the env-var hook) is the primary catch.

Test plan

  • `bun tools/hygiene/audit-tick-shard-relative-paths.ts` exit 0 (no new errors)
  • Only this tick shard staged; peer WIP (QG/Cayley-Dickson research) untouched

…green-ci rule

This session's empirical evidence (5 stale-armed PR investigations
between 13:10Z and 16:33Z) clarifies three distinct resolution
patterns: close-as-redundant, re-land-via-cherry-pick, and
forward-signal-comment. Added a decision tree and links to the
empirical instances.

Composes with the forced-escalation-finds-hidden-work anchor on
holding-without-named-dependency rule (PR #3901).

…med-dep loop closed

1h 03m cascade from 1531Z → 1634Z. PRs #3897 (B-0462), #3898 (1535Z
shard), #3900 (1547Z shard), #3903 (1610Z + path-depth table) all
merged. PR #3906 (fix-1547z-on-main) auto-merging cleanly (22/25
SUCCESS, 2 pending).

Substrate-honest lessons:
- Auto-merge race (sub-case 5 of claim-acquire saturation-ceiling)
- Lint check classification: broken paths on main propagate as
  new errors to subsequent PRs via the audit's all-shards scan
- Path-depth reference table (1610Z, PR #3903) is the durable
  substrate fix

Persistent contamination: git branch --show-current caught HEAD-shift
to 5 different peer-Otto branches across 5 cron fires; no commits
landed on peer branches.

Pull request overview

Docs-only tick shard documenting a 1-hour cascade of 5 PRs landing, plus an addition to a rule file describing three resolution patterns for stale-armed PRs.

Changes:

  • New tick shard 1634Z.md summarizing the cascade, substrate-honest lessons (auto-merge race, lint propagation, path-depth table), and persistent branch-contamination observations
  • New "Stale-armed-PR resolution patterns" section in blocked-green-ci-investigate-threads.md with decision tree (close-redundant / re-land-cherry-pick / forward-signal)
