Investigated whether this session caused the 11:33 hard freeze. It did
not, and the evidence is recorded in the evidence artifact:
- No OOM kill, no oom_reaper, no hung-task or soft-lockup message, and
no kernel message AT ALL after 11:20. The log stops mid-line at
11:33:15 -- a hard hang, not a process the kernel was fighting.
- Last commit 11:30:32; last jail trace 11:11:57, 21 minutes earlier.
The session was idle when the machine died.
- Steam wrote a crash minidump at 11:31:10 and at-spi2 disabled an
unresponsive app at 11:32:06, on an RTX 3090. Correlation only -- a
hard hang leaves no log to prove cause.
- Nothing survived the reboot: no stray unshare/kcov, no leftover
tmpdirs, no leaked mounts, and the live /etc and /usr/local/bin
files keep their original dates.
Hardened anyway, because the jail had one genuinely unbounded
behaviour: a case could run forever. Two hangs yesterday came from a
`crontab -` fallback inheriting the caller's stdin.
Each case now runs under `timeout --kill-after=10s` (default 120s,
--timeout to override) with stdin from /dev/null, and a timed-out case
WARNS by name instead of being swallowed -- a silent timeout looks
identical to an unreachable line in the report. Verified: a `sleep 600`
subject now ends in 5s with --timeout 5s.
dot_resolver_install.sh still measures 39/39 = 100.00%.
