* feat(common): add MRF intent channel and Mrf request source (HS-01)
Introduce the producer-facing half of the mission repair feed: a global
bounded (8192) channel carrying lightweight MrfIntent values from IO
error paths, plus the RUSTFS_HEAL_MRF_ENABLE delivery kill-switch and
config constants for queue/journal sizing. Delivery is strictly
non-blocking (try_send, drop-on-full) so it can sit on decode-failure
and partial-write paths without adding latency. HealRequestSource grows
a 'mrf' variant so admission accounting can attribute replayed intents.
Part of backlog#1865 (option a: wire HealEvent-style intents with a
durable retry ledger).

* feat(heal): add MRF queue, durable journal, and intent consumer (HS-01)
Consumer half of the mission repair feed: a bounded pending queue
(100k intents / 8 MiB dual ceiling, drop-newest on overflow), a durable
journal at buckets/.heal/mrf/journal.bin holding the unaccepted pending
snapshot, and a consumer task that batches intents off the global
channel, translates them into prioritized heal requests (decode
failure -> Urgent ECDecode, metadata corruption -> High Metadata,
partial write -> Normal object heal), and retries full admissions with
a 5s backoff and a 3-attempt ceiling.
Durability: every journal record carries its own CRC32 and a
format/version header, so a torn tail truncates cleanly at replay; the
journal is deleted after a successful replay and when the pending set
drains (mirroring MinIO's post-replay list.bin unlink). Losing the last
500 ms flush window is acceptable: replayed duplicates merge via the
manager dedup key and read-repair remains the safety net.
Metrics: rustfs_heal_mrf_queue_depth/_queue_bytes, _dropped_total
{reason}, _replayed_total, _journal_bytes, _journal_fsync_total.
The consumer is wired at heal runtime bootstrap right after manager
start, honoring RUSTFS_HEAL_MRF_ENABLE (default on, rollback = off).
Tests: unit tests for the dual ceiling, record roundtrip, torn-tail
truncation, and the priority mapping; integration tests against a real
4-disk ECStore proving channel intents reach the manager queue as
Urgent/mrf-attributed requests and journal replay arms intents, drops
torn tails, and removes the file.
Part of backlog#1865 (option a).

* feat(ecstore,scanner): deliver MRF intents from error paths (HS-01)
Wire the three production delivery points, each a single non-blocking
try_send next to the existing in-memory heal paths, which stay as the
fast path:
- read.rs decode-error branch: DecodeFailure intent beside the existing
read-repair submit, so an Urgent ECDecode request survives restarts
even when the Low-priority read-repair request was dropped or lost.
- add_partial: PartialWrite intent, giving partial-write recovery a
durable Normal-priority object heal across restarts.
- scanner_folder metadata-corruption classification: MetadataCorruption
intent beside the existing High-priority scanner heal request.
All three are on error paths only: zero cost on healthy IO.
Part of backlog#1865 (option a).

* feat(scanner): emit excess alerts as S3 notification events
The excess-versions / excess-version-size / excess-folders alerts were
metrics-and-logs only; consoles and external auditors had no way to hear
them (rustfs/backlog#1868, HS-04). MinIO emits s3:ObjectManyVersions /
s3:ObjectLargeVersions / s3:PrefixManyFolders for the same conditions —
RustFS carries those as EventName::Scanner* with s3:Scanner:* wire names
that already existed unpublished.
The three alert sites now also dispatch through the standard event
pipeline (send_event via the storage_api owner facade), carrying the
actual values and thresholds in req_params and UserAgent "Scanner".
Without a cooldown a single over-threshold object would re-emit on every
~60s scan cycle, so emissions are edge-held per (kind, bucket, object)
for 24h (RUSTFS_SCANNER_ALERT_COOLDOWN_SECS, 0 = every cycle), backed by
a process-global map with a 4096-key hard cap that clears rather than
grows. Metrics and structured logs stay level-triggered every cycle;
only the notification events are held back. A restart resets the
cooldown deliberately: one re-emission per still-hot key buys back
visibility after the restarts that accompany incident response.
Tests pin the edge-hold semantics (first fires, immediate re-check held,
independent keys, cooldown expiry re-fires, zero cooldown always emits,
hard bound) in one sequential test for the process-global map, and pin
the emitted wire names against EventName's canonical string forms so a
subscribed bucket notification can never silently stop matching.
docs/operations/scanner-excess-alerts.md documents the three events,
the metric-vs-event cadence difference, and the HS-15 threshold deltas
(alert_excess_folders 65538 vs MinIO 50000 is deliberate: Proxmox
Backup Server chunk layout compatibility).
Closesrustfs/backlog#1868.

* feat(heal): track erasure set progress baseline
Record erasure-set heal byte progress from per-object results and seed progress totals from complete usage-cache snapshots when available.
Keep usage-cache failures observational so heal execution continues without a baseline.

* feat(heal): skip filtered erasure set versions
Skip erasure-set versions written after the durable heal start time, and queue lifecycle-expired versions for expiry before skipping them.
Track new-version and ILM-expired skips separately so progress can explain completed baseline work without treating these skips as retry-blocking failures.

* feat(heal): wire abandoned data-dir cleanup check
Connect check_abandoned_parts through ECStore, pool, and set layers so heal can invoke the existing orphan data-dir reclaim path instead of returning NotImplemented.
Add dry-run support to the reclaim scan and cover dry-run plus scoped set behavior with regression tests.

SizeSummary::tier_stats was populated for every scanned object but
apply_scanner_size_summary dropped it, so per-tier usage never reached
DataUsageInfo. Wire it through the same merge chain repl_target_stats
already uses, up to DataUsageInfo::tier_stats.
DataUsageEntry used the derived MessagePack encoding, which serialises
structs as arrays: appending a field turns the whole cache into a decode
error for older readers, so mixed-version nodes would invalidate each
other's cache every scan cycle. Give it the same hand-written
map-encoded Serialize DataUsageCacheInfo already carries, and record the
invariant in AGENTS.md.
Widen TierStats counters from i32 to u64 so a tier past 2^31 versions
cannot make checked_merge reject an entire usage snapshot, and drop the
duplicate TierStats/AllTierStats definitions in the scanner crate in
favour of the data-usage ones.
versions_scanned for both the scanner and ILM collectors was read from
the Lifecycle work source's `checked` counter, which is never recorded on
the production scan path — so rustfs_scanner_versions_scanned_total and
rustfs_ilm_versions_scanned_total sat at zero even while objects_scanned
climbed. The two metrics also have distinct intended meanings that were
conflated: "versions scanned" (all versions, any bucket) vs "versions
checked for ILM actions" (lifecycle-configured buckets only).
Add a lifetime `versions_scanned` counter recorded for every version the
scanner walks (independent of ILM), and record the Lifecycle source's
`checked` counter from the ILM evaluator so the ILM metric reflects the
real checked subset. The scanner collector now reports total scanned
versions; the ILM collector keeps the ILM-checked subset.
Closes backlog#995 (OBS-09).
