desktop.log is an append-only forensic log written via appendFileSync / fs.promises.appendFile with no rotation. When the backend enters a boot loop — e.g. the version-skew crash where an old app shell spawns `dashboard --tui`, argparse exits(2) instantly, and the renderer keeps retrying — the full bootstrap transcript plus repeated stack traces are appended on every attempt. In the wild this drove a single desktop.log to ~326 GB, exhausting the disk and breaking `hermes update`/install (git index.lock, venv rebuild, and npm all need scratch space). Rotate to a single .1 sibling once the live file crosses a 10 MB cap, so total on-disk usage stays ~2x the cap while preserving the most recent transcript for diagnostics. The size check runs before each append in both the sync (shutdown) and async (steady-state) flush paths. All filesystem ops stay inside try/catch so logging can never block startup/shutdown or crash the shell — consistent with the existing append error handling. Paired with the CLI --tui back-compat guard in this PR: the guard stops the crash loop from starting, and this stops a crash loop (from any cause) from ever filling the disk. |
