| File | Description |
|---|---|
| docs/research/shadow-lesson-log-20260522-stale-locks.md | Adds a new “shadow lesson log” about stale git locks (currently appears out-of-scope for a PR-discussion preservation PR and overlaps an existing stale-locks lesson log). |
| docs/pr-discussions/PR-4909-shard-2026-05-25-0443z-20th-dotgit-anchor-7th-consecutive-0.md | Adds the archived PR discussion content for PR #4909 (includes one relative link that should be corrected to remain navigable). |
| # Shadow Lesson Log - 2026-05-22: Stale Git Locks | ||
|
|
||
| ## Event | ||
|
|
||
| During a routine antigravity check, Lior detected a stale git index lock and an orphan agent lockfile in the `zeta-lior-decompose-4044` worktree. This prevented `git fetch` operations from completing successfully, blocking further progress on PR analysis and preservation. |
| 1. **7th consecutive clean** — saturation recovery operationally robust across short (≤36min) AND long (>1h) cadence | ||
| 2. **First clean cold-boot** in the 20-anchor series — claude-loop's per-session worktree allocation may be structural protection vs the peer-branch-contamination failure mode documented at #5/#7/#8/#10/#12/#13/#19. Naming the hypothesis; will see if it holds across #21+ | ||
| 3. **Cadence resumed at 36min** after #19's 1h24min gap — refutes #19's Possibility D (operator-side pause). New Possibility E (inherent variance) preserved alongside C (longer-cycle self-tuning) | ||
| 4. **Otto lane STILL empty** (0 PRs) vs Lior lane dominant (60 PRs). Lane discipline holds: the autonomous-loop prompt's generic "fix BLOCKED PR threads" instruction is **boilerplate**, not operative cross-lane authorization (per [`mechanical-authorization-check.md`](../../../../../../.claude/rules/mechanical-authorization-check.md)) |

The link target uses six parent traversals (../../../../../../.claude/...) from a file that is only two levels deep under docs/pr-discussions, so it resolves outside the repository (effectively /.claude/...) and 404s on GitHub. This breaks the provenance trail the archive entry is trying to preserve, because readers cannot reach the referenced mechanical-authorization-check.md rule from this document.
