`go test -timeout` is per package, so the budget has to clear the slowest
single package: internal/handlers. Measured in a cache-defeated builder
stage on the 48-core shared build host, 2026-08-18:
16.9s host load 5-20, GOMAXPROCS 48
45.9s / 47.3s / 49.0s three runs at deliberate host load 31-73
30.6s / 39.7s host load 5-20, GOMAXPROCS 6 / 4
67.3s / 97.5s host load 5-20, GOMAXPROCS 2 / 1
67.3s GOMAXPROCS 4 at deliberate host load 52-68
The old 30s budget was breached by every loaded run and by every
GOMAXPROCS at or below 6. At GOMAXPROCS 4 it failed outright on plain
33e4fa4 with no other change ("panic: test timed out after 30s"); with
90s the same run passes at 41.816s.
90s is the org-wide backstop in REPO_POLICIES.md. It holds against these
measurements: the worst case under native parallelism is 49.0s, and the
compound GOMAXPROCS-4-under-load case at 67.3s sits at 75% of it. The
one figure above 90s is GOMAXPROCS 1, a synthetic core floor rather
than a condition CI runs under.
No test is changed, skipped, shortened or desampled.
