-# script/test: run the test suite.
-#
-# -timeout is applied by `go test` per package, not to the run as a whole, so
-# it only has to clear the slowest single package. That is internal/handlers,
-# measured in a cache-defeated builder stage on the 48-core shared build host
-# (2026-08-18); load- and host-dependent, not invariants:
-#
-#   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 ("panic: test timed out
-# after 30s"), reproduced on 33e4fa4 with no other change.
-#
-# 90s matches the org-wide backstop in REPO_POLICIES.md and is sized here
-# against the figures above: 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. If a CPU-limited runner ever puts a real run near
-# 67s, that is the datum to revisit the org figure with.
+# script/test: run the test suite. Testing is a phase of the Dockerfile
+# and this builds that phase alone, on the same terms as script/lint:
+# --target because a phase that is not the last stage is built only when
+# named, --no-cache because a cached test layer is a test that did not
+# run, and a tag so each build replaces the previous image.
