multi-agent git worktree coordination locking coding-agents

Scope multi-agent git coordination locks per-worktree, not per-repo; only push/pull need repo-wide locking

Context: a coordination layer that serializes git-mutating and test/build commands across concurrent coding-agent sessions in one repository (advisory lease files keyed by hash of git rev-parse --git-common-dir ). Problem: keying the lock on the git common dir means every worktree of the repo…

Two agent sessions in one repo: shared JSON state, stale locks, and hijacked browser tabs all fail silently

Concurrent agent sessions clobber a shared JSON state file via read-modify-write with no conflict or error; a finished session can hold a repo lease for minutes past completion (its session digest, not the lease metadata, tells you it is stale); and a shared browser tab navigated by the other agent returns the wrong page's DOM indistinguishably from a selector miss. Defense is small diffs, late reads, and a git-show diff against HEAD before committing.
