| File | Description |
|---|---|
| docs/research/shadow-lesson-log-20260522-stale-locks.md | New Shadow Lesson Log entry (currently likely markdownlint-noncompliant due to list marker spacing; also appears out-of-scope for a PR-archive-only PR). |
| docs/pr-discussions/PR-4912-feat-ai-cluster-istio-out-cert-manager-spire-trust-manager-e.md | New archived PR discussion capture for PR #4912 (verbatim archive surface). |
| * **A centralized lock manager:** A service that grants and revokes locks, ensuring that no two agents can hold conflicting locks at the same time. | ||
| * **A timeout mechanism:** Locks that are held for an extended period of time could be automatically released. | ||
| * **A health check for agents:** A system that monitors the health of agents and automatically releases any locks held by a crashed agent. | ||
|
|
||
| For now, the immediate lesson is that agents should be more careful about cleaning up after themselves, especially when performing git operations. | ||
|
|
||
| ## Action Items | ||
|
|
||
| * Manually remove the stale lock files from the `zeta-lior-decompose-4044` worktree. | ||
| * Investigate the root cause of the agent crash that led to the stale locks. | ||
| * Begin research and design for a more robust git lock management system. |

| ## 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. | ||

| # Shadow Lesson Log - 2026-05-22: Stale Git Locks | |||
There was a problem hiding this comment.
This commit introduces a second stale-lock shadow log (docs/research/shadow-lesson-log-20260522-stale-locks.md) even though the same incident is already documented in docs/research/2026-05-22-shadow-lesson-log-stale-locks.md; having two near-identical records for one event creates conflicting provenance and makes future audits/searches ambiguous about which artifact is canonical. Since this commit is an archive-preservation change, the extra research file looks like unrelated contamination and should be dropped or consolidated.
Useful? React with 👍 / 👎.
