.atomic_write_json(path, payload) ⇒ Object

Atomically replace a JSON state file.

The temp name must be unique per write, not just per process. Several threads in one session write the same registry path — the startup persist, the inbox delivery thread, and one thread per API client — and a shared temp name lets one thread rename the file another is still writing, which surfaces as ENOENT on the loser's rename. mkdir_p covers a state directory that was reaped (tmpfs, operator cleanup) while the process was live.

.git_capture_end(repo_root, start, exclude_paths: nil) ⇒ Object

Captures committed and in-progress work relative to the state observed at session start. Passing the full git_capture_start hash avoids treating an unchanged pre-existing dirty tree as worker activity; a SHA string remains supported for older callers.
