* fix(tier): gate exact remote version consumption
Reject non-empty remote tier versions before transitioned GET and remote delete backend I/O when the tier backend does not support exact version operations.

* test(tier): split mock remote version validation fault
Separate one-shot mock remote version validation failures from persistent unsupported-backend behavior so cleanup durability tests can still verify exact-version recovery while #1358 fail-closed gate tests keep asserting no backend I/O.

Advance transition transactions to UploadOutcomeUnknown before remote tier PUT so response-loss windows can be recovered through provider-authoritative probing.

* feat(tier): add transition candidate probe contract
Add a fail-closed WarmBackend probe contract for provider-authoritative transition candidate state. Default providers report Unsupported, while the shared mock backend can now model missing, unversioned, and exact-version candidates for follow-up recovery tests.
This is a forward-compatible foundation for #1352/#1358 recovery work and does not change production cleanup behavior.

* feat(tier): probe transition candidates from providers
Implement provider-authoritative transition candidate probing for S3-family warm backends by querying ListObjectVersions with exact-key filtering and fail-closed classification for delete markers, multiple versions, truncation, and unknown versioning state.
This keeps non-S3 providers on the default Unsupported probe result and forwards MinIO, RustFS, and R2 through the S3 probe implementation.

* fix(tiering): make rejected upload cleanup durable
* fix(tiering): close transition upload cancellation gap
* test(tiering): cover failed upload without candidate
* test(tiering): synchronize cancelled cleanup recovery
* test(tiering): stabilize cancelled cleanup recovery
Prefer cancellation when the tier delete journal recovery worker is racing an immediate tick, and build the cancelled-cleanup regression store with an already-cancelled token so production recovery cannot consume the test journal.

test(ilm): re-enable test_transition_and_restore_flows; fix test-util disk-open and restore error-path lock (rustfs/backlog#1303)
The excluded test's 'missing xl.meta ... on disk2' was NOT an EC
metadata-distribution issue: after a transition all four shard disks hold
a fully consistent xl.meta (verified by decoding each shard). The panic
came from the tier test util's open_disk, which hardcoded disk_index 0
for every disk path; LocalDisk::new validates the endpoint's
(set_idx, disk_idx) against the disk's own format.json and rejected every
non-slot-0 disk with InconsistentDisk, which read_transition_meta
collapsed into 'missing xl.meta'. Derive the real indices from
format.json instead. This also un-breaks free_version_count /
wait_for_free_version_absence for non-first disks (silently 0 before).
With that fixed, the test advanced to the #4877 restore self-deadlock,
whose main paths #4886 already fixed. Complete that fix on the one path
it missed: update_restore_metadata (the restore-failure metadata
rewrite) still rebuilt copy_object options with no_lock=false and would
re-acquire the object write lock the restore handler already holds.
Propagate the caller's no_lock there too.
Remove the test from the serial-lane exclusion list; the four remaining
exclusions are unrelated known issues and stay.
* test(ecstore): extract shared MockWarmBackend into a test-util feature (backlog#1148 ilm-6)
The tier/lifecycle integration tests carried two byte-for-byte copies of an
in-memory WarmBackend mock — one in crates/scanner/tests and one in
rustfs/src/app — plus duplicated register_mock_tier and polling helpers. Both
implemented the same ecstore WarmBackend trait.
Consolidate them into ecstore behind a new `test-util` feature, exposed via the
`rustfs_ecstore::api::tier::test_util` facade:
- MockWarmBackend: in-memory WarmBackend with an operation log (for ordering
assertions such as "local delete precedes remote remove") and fault injection
(FaultConfig): unreachable, HTTP 5xx, credential rejection, injected latency,
plus external_remove to simulate an out-of-band remote deletion.
- register_mock_tier / register_mock_tier_backend: register the mock into any
TierConfigMgr handle (the global manager used by scanner tests or a
per-instance one used by the app tests).
- xl.meta transition assertion helpers: read_transition_meta,
assert_transition_meta_consistent (cross-shard consistency of the
status/tier/remote-key/remote-version-id tuple plus free-version count), and
free_version_count.
- polling helpers: wait_for_remote_absence, wait_for_object_count,
wait_for_free_version_absence.
Both existing copies now consume this single definition; `rg 'struct
MockWarmBackend'` collapses to one. The feature is enabled only from
[dev-dependencies], so it never links into the production binary (resolver 3).
Designed for downstream ilm-8 (restore lifecycle) and ilm-11 (tier fault
injection matrix). Coordinates with #4706 (ilm-2), which adds op-logging to the
scanner mock — that op-logging is now part of this shared surface, so #4706
should rebase onto it.
Refs rustfs/backlog#1148 (ilm-6), rustfs/backlog#1155.
* test(ecstore): fix shared MockWarmBackend usage after main merge
- Access stored objects via MockWarmBackend::contains() instead of the now
private inner objects map (fixes E0609 after the shared test-util refactor).
- Drop dead ReadCloser/ReaderImpl/DiskAPI imports and the unused
transition_api test re-exports the mock extraction left behind.
- Reword the scanner/rustfs test-util dependency comments so they no longer
embed the literal rustfs_ecstore:: path that trips the ECStore
architecture-migration guard.
