…dget A slow runner failed the Rust tests job on test durations alone, with every test passing: five tests ran just past their bounds. - pplx-space-node-mgr receive_keeps_destination_identity_through_scrub_and_publication and pplx-space-spaced-guest-worker::embedding took 4.7 s against the 4 s failure bound and had no exception. They get one at the file's formula, 1.5 times the slowest time, rounded up: 8 s. - Three pplx-space-db-migrate bootstrap tests, already listed, ran 7.0 s and 5.7 s against ceilings of 7 s and 5 s. Each bootstraps its own Postgres database and applies every migration, which the file names as setup a test can't shorten without proving less. Their ceilings go to the same formula: 11 s and 9 s. Raising those three goes against the file's "never raise a ceiling" rule. The alternative, making them faster, means sharing one migrated database across tests that each prove a fresh bootstrap, so this keeps the tests and widens their ceilings instead.

Summary
Merging this stops a slow runner from failing the Rust tests job on test durations when every test passes. On #1553's run, all 12,433 tests passed, and five then ran just past their bounds (
ci/test-duration-budget.toml):pplx-space-node-mgr service::artifact_fs::receive::tests::receive_keeps_destination_identity_through_scrub_and_publicationandpplx-space-spaced-guest-worker::embedding embedding. Each gets one at the file's own formula, 1.5 times the slowest time, rounded up: 8 s.pplx-space-db-migratebootstrap tests at 7.0 s (ceiling 7) and 5.7 s (ceilings 5). Each bootstraps its own Postgres database and applies every migration, setup the file names as unshortenable. Their ceilings go to the same formula: 11 s and 9 s.Validation
tomllib. Every exception stays abovefail_seconds, which the check requires.Severity and risk
Severity: low. A pull request with passing tests fails on a slow runner.
Risk: a real slowdown in these five tests would go unnoticed up to their new ceilings. Roll back by reverting this PR.
Not covered
Raising the three db-migrate ceilings goes against the file's "never raise a ceiling" rule. Making them faster instead would mean sharing one migrated database across tests that each prove a fresh bootstrap. If that's preferred, this PR can shrink to the two new exceptions.
