Adds a serial-lane ILM integration regression test that pins the
local-first ordering contract established by rustfs#3491, where
`expire_transitioned_object` deletes local metadata BEFORE any remote
tier cleanup so a concurrent GET can never observe live local metadata
pointing at an already-removed remote tier version (user-visible
`NoSuchVersion`).
`serial_tests::test_expire_transitioned_object_never_races_concurrent_get`
in `crates/scanner/tests/lifecycle_integration_test.rs`:
- Transitions an object to a mock warm tier, then runs a tight
concurrent GET loop while calling `expire_transitioned_object`; every
GET must return a full, correct body or a clean object/version-not-found
-- never a tier-fetch failure.
- Deterministic ordering assertion (revert-proof): immediately after
expiry the remote tier object is still present and the mock recorded
zero remote `remove` calls, proving remote cleanup is deferred to
free-version recovery. Reverting to remote-first ordering turns this
assertion red.
Supporting changes:
- Re-export `expire_transitioned_object` from `api::bucket::lifecycle`.
- Record remote-tier mutating ops in the scanner test `MockWarmBackend`.
- Update tier-ilm-debugging.md to reference the new regression test.
Runs in the CI ILM Integration (serial) lane (ci.yml
test-ilm-integration-serial), picked up by the existing
binary(lifecycle_integration_test) filter.

Implements ilm-1 from the ILM test-strategy plan: the 33 #[ignore]d ILM
integration tests (14 in crates/scanner/tests/lifecycle_integration_test.rs,
19 in rustfs/src/app/lifecycle_transition_api_test.rs) never ran anywhere.
This adds a dedicated serialized CI job and repairs the app-layer suite,
activating 29 of them.
- ci.yml: new test-ilm-integration-serial job running the two ILM test
surfaces with 'cargo nextest run -j1 --run-ignored ignored-only'. The
tests share process-global singletons and fixed ports (9002/9003);
serial_test's #[serial] does not serialize across nextest's
process-per-test boundary, so -j1 is the serialization mechanism.
- app suite repair: the 19 app tests rotted after the InstanceContext
migration (usecases resolve the store via AppContext; the test env never
installed one, so every store-touching call failed with InternalError
'Not init'). Add a test-only install_test_app_context helper behind the
sanctioned context/runtime_sources boundaries and switch the tests from
without_context() to from_global(). All 19 now pass.
- delete test_lifecycle_transition_basic (+3 orphaned helpers): required
an external MinIO at localhost:9000 and slept 1200s; superseded by the
mock-tier tests in the same file.
- fix a timing flake: poll free-version metadata removal instead of
asserting a single read right after remote-object absence.
- 3 scanner tests fail on main for product reasons (multipart restore
UnexpectedEof; noncurrent transition/expiry after immediate compensation
transition on versioned buckets); they keep #[ignore] with a backlog
reference and are excluded from the lane by name.
Lane: 29 tests, ~43s test time, green twice locally.
