A wrong published value now reports its Success/Value/Reason/StatusCode, the
publish's wall time against the run budget, the run guard's in-flight /
refused / quarantined counters, thread-pool and GC state around the call,
the shadow stats, and the tails of the script and runner logs.
Reproduced under heavy load (32 `yes`, test at nice 20, load avg 300+):
3 of 8 runs failed, every one because the SIBLING's shadow run missed the
300 ms soft deadline in the starved worker ("shadow Failed [budget] script
timed out after 0.3s") and was rightly recorded as a sibling mismatch. No
published value was ever wrong. The out-of-process soft deadline is armed at
submit, so it covers the pipe round trip and worker scheduling too.
The run budget (which is also the worker's soft deadline) goes to the 2 s
production default; no assertion changes. The runaway still runs away and is
killed at T + HardGrace, so nothing the test proves depends on T being short.
