copyIfNewer read/wrote a member file of up to 256 MiB with readSync/writeSync,
blocking the event loop for every user. It now copies with fs.promises 1 MiB
at a time from the runAs.openSafeAsync handle (owner/type check kept), keeps
the 256 MiB member cap and zero-run holes, writes a temp file and renames it
into place, and joins a copy already in flight for the same destination.
A failed copy is logged and never rejects; snapshotTranscript is async and
all three import callers await it.
Internal SmartGift build of a Claude Code monitoring dashboard.
Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.
Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.
Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.
