 The coordinator creates its durable record and peer `Prepare` blocks new reference creation, drains exact tier-operation leases, and proves that edit/remove/clear will not strand authoritative references. Prepare, Commit, and Abort use all-node fanout rather than quorum: independent peer calls use a work-conserving concurrency limit of four, a 30-second per-peer deadline, and a 30-second fanout-wide deadline; Prepare is additionally capped by the intent expiry. The coordinator collects every completed outcome. A timed-out or otherwise ambiguous started Prepare is included in compensating Abort because cancellation does not prove the peer failed to persist its fence; peers not started before the fanout deadline make Prepare fail but do not require Abort. The coordinator then conditionally writes tier config, durably commits the coordinator intent, releases its exclusive guards, requires every prepared peer to commit, publishes the runtime candidate, and clears the block. Per-mutation sharded mutexes serialize local phases only; persisted intent plus tier-config ETag is authoritative.

+Terminal recovery does not reinstall a process-local operation fence when the published in-memory manager has the exact committed candidate digest. This exception affects only ordinary tier-operation leases: recovery still replays peer `Commit`, retains and conditionally cleans the durable evidence, and blocks a new tier configuration mutation until the recovery snapshot is quiescent. A different local digest remains fenced until the committed candidate is safely published.

+## Cleanup With The Scanner Disabled
+
+With `RUSTFS_SCANNER_ENABLED=false`, startup makes one controlled attempt to finish a previously persisted cycle reset whose validated recovery marker is already `cleanup-pending`. This is metadata cleanup only: it does not start the ordinary scanner loop, scan namespaces, accept a new reset request, or automatically perform a usage-state `full-rebuild`. Missing, merely `blocked`, unknown-version, unknown-phase, or corrupt markers do not authorize an automatic reset.
+
+The attempt uses the existing leader lock and revalidates the observed marker revision and phase after acquiring it. A busy leader or data-movement pause leaves the marker intact and is reported through `cycle_recovery.state` and `cycle_recovery.reason` in the existing scanner status response. There is no automatic retry loop while disabled. After resolving the blocker, explicitly retry `POST /v3/scanner/cycle-state/reset` with `{"mode":"full-rescan"}`, or restart to make another controlled attempt. The v3 reset routes remain synchronous and return their existing successful HTTP 200 responses; no asynchronous HTTP 202 acceptance is introduced.
+
+The startup probe is cancellation-aware and uses the existing cache persistence I/O timeout. Shutdown waits only for the existing server shutdown timeout. If the cleanup task cannot join in that window, the `scanner_cleanup_not_joined` warning means completion is unconfirmed, not drained. The task is not force-aborted or force-unlocked while its runtime remains alive; it retains its existing namespace/admission guards, and durable marker/fence state remains authoritative. Inspect status before retrying. This does not establish a hard deadline for an unresponsive storage operation or prove that I/O has drained when the process or runtime subsequently exits. Task-ownership timeout tests are not storage fsync, commit-tail, or process-crash durability evidence.
+
 ## Data Movement Pauses

 RustFS uses a `global_pause` policy while pool decommission or rebalance can hide scanner metadata: usage publication, lifecycle discovery, tier cleanup discovery, scanner-originated heal and bitrot checks, and replication discovery are deferred together. A failed or canceled decommission remains a publication barrier until an operator retries or clears it. The same pause and estimate objects are included in `GET /v3/ilm/expiry/status`.
@@ -301,6 +309,24 @@ The pacing gate holds neither namespace locks nor I/O/page permits while sleepin

 A missing provider, zero pause, or both class thresholds set to zero preserves unpaced execution. Missing counts follow the existing shared pressure interpreter; they are observations, not health, quorum or resource-ownership proof. The current provider exposes node-level workload classes, so this does not claim independent per-set foreground measurements or a hard global resource budget. Runtime waits increment `rustfs_heal_mainline_throttle_total` with `source=admin`, `result=delayed`, and a foreground-pressure or `recovery_window` reason. Real p99/throughput protection requires the separate W20 fixed-load ABBA measurements.

+## Pending Heal Hints
+
+The scanner's persisted pending-heal cache is a best-effort retry backstop, bounded to 10,000 hints per bucket and a 24-hour age limit. These limits do not authorize garbage collection of committed durable repair obligations. A durable owner must retain its independent replay record until verified object completion or an equivalent durable successor permits removal.
+
+Accepted, merged, or policy-dropped admission does not clear an existing hint. Task completion and legacy repair notices also lack the incarnation, set scope, generation, and storage verification needed to prove repair responsibility was discharged. The legacy success path therefore retains hints conservatively; this is not a complete durable MRF handoff protocol.
+
+Pending retries use their persisted attempt count and last-attempt timestamp, starting at 15 minutes and doubling up to six hours. Each bucket submits at most 128 due hints per cycle. Already admitted or policy-dropped hints retry at Low priority; queue-full hints keep High priority but obey the same due-time bound. A changed retry batch synchronizes its pending cache once, including when cancelled, rather than copying the entire table after every admission.
+
+Rediscovery and admission observations update the recorded result but do not postpone an already armed retry. The actual retry loop advances the attempt count and timestamp before awaiting admission, so cancellation or repeated queue-full results cannot reset the retry budget.
+
+| Producer | Current identity and compensation | Durable handoff boundary |
+|---|---|---|
+| Scanner corrupt metadata | Metadata kind with no invented version/set; an existing pending-cache hint remains available for bounded retries. | Cache publication is separate from MRF ingress. Its age/count limits mean it is not an irrevocable repair-obligation ledger. |
+| Read decode failure | Decode kind, available version and erasure-set scope; a later failing read can rediscover the repair. | Nonblocking ingress and in-memory read-repair admission do not acknowledge durable acceptance. |
+| Partial write | Partial-write kind, available version and erasure-set scope; an in-memory heal request is the fast path. | The caller's documented restart-survival requirement is not fulfilled by ignoring the ingress result or by removing the unaccepted journal record at manager admission. Verified durable ownership remains pending. |
+
+Legacy notices carry only bucket/object/version, not a verified storage disposition, incarnation, scope, or durable responsibility generation. They are drained without clearing hints. Terminal callbacks release only their exact node-local ingress lease so rediscovery remains possible; lease generations are not durable successor receipts. Pending migration staging is not activated, and this change does not enable durable tombstones or garbage collection. Positive cleanup requires a storage-owner receipt with the complete responsibility identity and validated commit/fence evidence; neither task status nor the bounded diagnostic outcome window supplies it.

+# Legacy Heal Outcome Compatibility
+
+This fixture executes the real `madmin-go` HTTP decoder and a pinned `mc` binary against synthetic v3 responses. Rust owner, admin adapter, and SDK tests validate the same JSON cases in `crates/madmin/tests/fixtures/heal-outcome-v3.json`. It does not run a storage repair or prove distributed recovery.
+
+Pinned primary sources:
+
+- `mc` release `RELEASE.2025-08-13T08-35-41Z`, commit `7394ce0dd2a80935aded936b09fa12cbb3cb8096`: [polling implementation](https://github.com/minio/mc/blob/7394ce0dd2a80935aded936b09fa12cbb3cb8096/cmd/admin-heal-ui.go#L414).
+- Its `madmin-go/v3` dependency is `v3.0.107-0.20250415152934-4b504b82db63`: [decoder and response type](https://github.com/minio/madmin-go/blob/4b504b82db633e978a57d49443b2be75824244c3/heal-commands.go#L101).
+
+The old decoder ignores additional JSON fields. The old poller returns success for `finished` without examining `detail`; only `stopped` returns a terminal error. Consequently `completed_with_errors` retains its canonical outcome and complete traversal coverage, but uses legacy summary `stopped`. `completed` describes execution only: unknown storage receipts remain `unknown`, not `repaired`.
+
+Run from the repository root with an isolated tool cache and binary directory:
+
+```sh
+(
+set -eu
+compat_dir=$(mktemp -d)
+trap 'rm -rf "$compat_dir"' EXIT
+export GOPATH="$compat_dir/gopath" GOMODCACHE="$compat_dir/mod" GOCACHE="$compat_dir/cache" GOBIN="$compat_dir/bin"
+export CGO_ENABLED=0 GOTOOLCHAIN=local GOMAXPROCS=2
+go install github.com/minio/mc@v0.0.0-20250813083541-7394ce0dd2a8
+cd scripts/compat/heal-outcome
+MC_BINARY="$compat_dir/bin/mc" NO_PROXY=127.0.0.1,localhost go test -mod=readonly -p 2 -count=1 -v ./...
+)
+```
+
+The subshell keeps the calling shell unchanged. `MC_BINARY` is mandatory and its Go build metadata must identify the pinned commit. Each subprocess gets a temporary mc configuration directory and synthetic credentials; it never edits the user's mc configuration. Loopback socket permission is required. The Go tests do not skip unavailable prerequisites.
+
+Six cases cover completed traversal, unknown repair proof, completed traversal with failures, cancellation, deadline, and untraversable listing. Two receiver cases carry a remote `finished` summary that contradicts an aborted or completed-with-errors outcome. The admin test applies the heal owner's wire validator to each `remoteResponse` and must produce the corresponding public `response`; the old CLI must then exit with an error. Unknown extension fields remain intact. Unknown or missing execution fields cannot validate a successful summary.
+
+New counters do not replace or reinterpret legacy progress. Outcome is a cumulative snapshot, not a page delta; `sinceSeq` only pages legacy result items. Result cursors and truncation markers remain separate from execution and traversal coverage.
+
+Two existing CLI limitations remain explicit: this mc does not terminate on `notFound`, and `-f` polling sends `forceStart` together with `clientToken`, a combination the RustFS v3 request contract rejects. The fixture uses the standard non-force polling flow. Neither limitation is hidden by emitting a new summary string or reporting a missing task as completed.

Preserve progress and bounded result cursors without treating legacy storage responses as repair proof. Add optional SDK outcome and cursor support with shared Rust fixtures, pinned legacy Go decoder and mc polling checks, and explicit compatibility limits.

houseme	0ee5408b94	feat(scanner): preserve bounded bootstrap admission fairness (#7260 ) feat(scanner): retain bounded bootstrap admission fairness Keep a leader-local bounded cohort across scanner retries and preserve waiting bucket priority during dirty arrivals and capacity overflow. Order source permits in the dispatcher without changing result identity, parent budgets, explicit cycle timing, or persistent coverage evidence.

houseme	3a4afe9b38	fix(heal): bound cross-page object retry delays (#7273 ) Retain failed identities in an execution-local count and byte bounded window so healthy later pages can advance. Preserve retry jitter, deadlines, terminal accounting and pressure pacing, with deterministic head-of-line and capacity regressions.

houseme	71859ff83c	fix(scanner): resume committed cleanup when scanning is disabled (#7281 ) Run one supervised cleanup attempt for an existing operator reset, with strict phase and revision checks under the original leader lock. Keep v3 reset authorization and responses unchanged, report deferred status, and bound probe and shutdown waits without aborting in-flight reset ownership.

houseme	cb72df269a	fix(heal): retain hints without verified repair receipts (#7275 ) Stop task completion and legacy notices from discharging scanner retry hints. Preserve existing hints and their retry due time across admission observations, bound retry scheduling, and synchronize changed batches once even on cancellation. Exercise the production MRF consumer, manager, event channel and scanner ledger. Document producer durability gaps without enabling successor activation or garbage collection.
