The install history was only surfaced as a « ~5m avg (3) » suffix next to a
distro. Entry [12] now shows what that history actually contains: totals and
success rate, period covered, median/min/max and cumulated duration, then a
breakdown by distribution, version and architecture, plus the current VMs and
the disk they occupy. « [r] » erases the history after confirmation.
record_duration() was only called on success, so no success rate could ever be
computed. Failures are now recorded with ok=False. They are counted separately
and EXCLUDED from the averages and the ETA: how long a failed install ran says
nothing about how long a successful one takes. Entries written before the flag
existed have no « ok » key and are read as successes, which they were.
Aggregation lives in qemu_install_monitor.py as pure functions (stats_summary,
stats_by, all_runs, reset_stats), display in todo.py — the split the file
already follows.
Disk presets extended to 400G, 600G, 800G, 1T, 1.5T and 2T. The parser only
understood G, so « 1T » would have been rejected: sizes are now normalised
through _qemu_parse_disk (1 T = 1024 G, decimal comma accepted), since the rest
of the chain reasons in gigabytes.
Verified with a synthetic history of 9 runs including 2 failures: the rate,
the per-group failure counts and the reset all behave; a group with no success
shows « — » rather than a misleading « ~0s ».
