Round-3 adversarial review, 2 blocking. Both fixed with mutation-verified
tests.
1. `mergeSwapVolumeFreeSpace` merged the volume reading into whatever sample
was current at RESOLUTION time, and `pressureSignal` then upgraded win32
from `available-commit-unqualified` to the decisive `available-commit` on
the strength of it. The `swapVolumeReadInFlight` latch makes every
intervening tick skip the merge, so the lag is as old as the last STARTED
statfs, not the last tick — and no age field exposed it, because
`systemMemoryPreGoneSampleAgeMs` describes only the synchronous memory read.
Reviewer's executed scenario: a statfs issued at t=0 on a healthy host
(40 GB free) resolving at t=20 s of commit pressure emitted
`SwapFreeMB: 200` beside `SwapVolumeFreeMB: 40000`, labelled
`available-commit`, with `SampleAgeMs: 0`. That reads as "the pagefile had
room, so this was not a commit refusal" — the opposite conclusion, wearing
the branch's highest-confidence label, on exactly the win32 G4-oom reports
this exists to decide.
The datum still ships (it is the only pagefile-expandability signal there
is), but now:
- the sample carries `swapVolumeSampledAtMs` — the tick that ISSUED the
statfs, never the one it resolved on — surfaced as
`systemMemoryPreGoneSwapVolumeAgeMs`;
- only a statfs that answers on its own tick may qualify the verdict.
`withSwapVolumeFreeSpace` takes `coTimed`; false keeps
`available-commit-unqualified`.
The next tick issues a fresh statfs, so the verdict recovers on its own.
2. The branch's sole production entry point — `startPreGoneCrashSampling()` at
main-process-ready-runtime.ts:128 — was untested. Deleting it left 691
tests across crash-reporting/ and startup/ green, while a comment in the
new test file claimed that gap was why the test was written. This is pure
instrumentation, so that one line is the whole of its value in the shipped
app. Added a source-level wiring test (the pattern this repo already uses
for arm-once ready-phase lines) that pins the import, exactly one call, the
call at statement indent, and that `main-process-ready.ts` awaits the
function it lives in. The misleading comment is gone.
Mutation-verified — each goes red alone:
coTimed -> always true 1 failed (verdict)
drop swapVolumeSampledAtMs age 1 failed (verdict test)
delete startPreGoneCrashSampling() 1 failed (wiring)
wrap it in `if (!is.dev) { ... }` 1 failed (wiring)
Verified: tsc -p config/tsconfig.node.json exit 0; oxlint
src/main/crash-reporting src/main/startup exit 0; 268 tests in
crash-reporting/ pass. Across crash-reporting/ + startup/ + memory/: 769
passed, 2 failed — both environment-dependent and failing identically on the
unmodified tree (Xvfb rebind, and a whole-repo glob census that times out).
