Module runlog 

The run log (DESIGN.md “Logging”): in memory for the progress panes, and on disk line by line for after a run that died. Only the UI thread writes it; workers post their lines.

Constants

KEEP_LOGS

Runs kept per game folder: enough that a re-run or two before asking for help cannot prune the run that failed.

Functions

log_dir

<game dir>\.pacenotes\logs, beside the ledger, so one folder holds everything this installer knows about one game.

log_path

One file per run, named by its utc_time::file_stamp, so reopening the installer to read a run cannot erase it.

prune

Deletes all but the newest keep run logs in dir, by name rather than modification time, so a log restored from a backup cannot pass for the newest; failures are ignored, since housekeeping must never stop an install.
