brokkr-smithy-dev asked how many times 3c was launched rather than
reconstructing it, and their reading was three. It was two.
#1 17:53:33 PDT killed by the power loss at step 80/604
#2 20:58:41 PDT stopped deliberately at 21:07:40, healthy
The phantom third came from a report I wrote at 23:03 narrating the
21:07 kill in the present tense with no timestamp. Every fact in it was
accurate; it was unreadable in sequence against a correctly-observed
22:46 snapshot of an idle GPU.
Evidence is ZFS birth times (a `>` redirect truncates the log but keeps
its birth, so mtime alone cannot separate "rewritten" from "created"),
plus the absence of any mtime under /tank/erp-tune after 21:07:34 — a
relaunch would have rewritten three files there.
Also pins the outage window to 18:14:45-18:17:00 PDT and corrects the
downtime from "~90 minutes" to 1h58m: the last journald entry before a
hard power loss is the last time anything wanted to log, not the moment
of the loss, and here it was 20 minutes early.
Corrects the in-flight header (step 22 -> last-logged step 24, stop
deliberate) and its stale "as of" stamp.
