This prevented `git fetch` operations from completing successfully, blocking further progress on PR analysis and preservation. + +## Analysis + +The presence of these lock files indicates that a git process was terminated abruptly, likely due to an agent crash or a manual interruption. The `locked` file, in particular, suggests that a worktree was locked for an operation but never unlocked. + +This event highlights a vulnerability in our autonomous system. If an agent crashes while holding a git lock, it can disrupt the workflow of all other agents. + +## Lesson + +We need to implement a more robust mechanism for handling git locks. This could involve: + +* **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.

Consider switching to the documented “hybrid” format: pipe-row first line, then the H1 body, and (if desired) move this metadata into a fenced ```yaml block inside the body instead of file-head frontmatter.
