 1. **Disk.** It restores or produces the workspace `target/`: `cargo build` or `cargo test` with `--all-targets`, `cargo nextest run --all`, or any reader of the `ci-dev` / `ci-feat-*` caches. The workspace test build leaves about 64 GB in `target/`; a hosted runner has about 14 GB.
 2. **Critical-path CPU.** It is a build that several downstream lanes wait on and would blow its timeout at 4 vCPU (`build-rustfs-debug-binary` gates the e2e and s3-tests lanes).
-3. **Hardware or environment.** Native aarch64 or access to the lab machines. Docker alone is not a reason: hosted Ubuntu ships Docker and supports the QEMU and Buildx setup actions.
+3. **Hardware.** Native aarch64, Docker-in-Docker, or the lab machines.
 4. **Cache ownership.** It reads a `rust-cache` key that a self-hosted job writes (see the cache rule below).

 Jobs that do only the following have no reason to be self-hosted: shell or Python scripts, `cargo fmt`, `cargo deny`, typos, actionlint, API calls (`gh`, dependency review, issue and stale bots, CLA checks), downloading an artifact and running a prebuilt binary, or a `cargo build -p rustfs` with its own cache key. `e2e-distributed.yml` and `e2e-upgrade.yml` build the server and the `e2e_test` harness on `ubuntu-latest` inside their budgets, so "it compiles something" alone is not a reason.

-The functional chain's `prepare` and `complete-chain` jobs, the performance runner availability check, and runner hygiene use `ubuntu-latest`: they inspect APIs or artifacts, not the lab hosts. The actual functional and performance suites remain on their lab runners. Functional-chain health collection stays on the operator-managed `smoke-testing` runner as part of the automation environment. Docker image packaging also uses `ubuntu-latest` for both musl and glibc variants; it downloads release binaries rather than compiling the workspace, and still sets up QEMU and Buildx explicitly.
-
-Moving these jobs off AKS reduces capacity demand, not necessarily the Azure bill immediately. VM costs fall only when nodes scale down or smaller capacity replaces them.
-
 A hosted runner is also the only choice for a few things the pods cannot do: `mount -o loop` and `mount -t tmpfs` fail inside the ARC pods, and a container runtime cannot guarantee that `io_uring_setup` is allowed. `uring-integration` and `e2e-distributed` are on `ubuntu-latest` for that reason, not for cost.

 ## Publication and Recovery

-Authenticated token queries first inspect the receiving node's in-memory automatic tasks. An original Scanner, MRF, automatic-Heal, or read-repair token can return its path-bound snapshot on that node, including the retained outcome and incremental cursor. The task source and original ID remain attached to the completion snapshot; aliases cannot enter this local query path. The local lookup never reads administrator recovery records.
-
-Administrator tokens and unknown local identities continue through the cluster coordinator. Starting and cancelling tasks retain their coordinator route. Querying another node does not discover or aggregate a remote automatic task, and this path does not extend automatic-task retention across process restart.

 The original schema-1 `terminal-root-heal-<token>.json` remains the commit marker. Its separate `heal-terminal-report-<token>.json` report has its own schema version and embeds the exact terminal identity. Both files belong to the same coordinator disk as the pending intent.

 Publication writes the report through the storage owner's conditional file update, writes the terminal marker, and then conditionally removes the pending intent. Recovery never treats a report without its marker as committed. A committed terminal continues to suppress stale pending work even when its report is unreadable. An initial publication failure leaves the existing responsibility available for recovery.
@@ -529,21 +529,17 @@ The OTLP exporter records these node-local histograms for completed manager admi

 The two new histograms aggregate all observed admission sources and results without per-request labels. An ordinary uninterrupted admission partitions the phase into wait and hold. Admin forceStart releases these guards while cancelling overlaps, then reacquires them: the cancellation gap is included only in the original total phase, and the second acquisition contributes to wait. Cancellation subroutine work is outside these outer admission guard intervals. Recording happens after all three guards are released. They measure manager admission ownership, not namespace/object-lock waiting during repair. The status field `maxLockPhaseMicros` remains a manager-lifetime maximum, not a p95 sample. Keep same-window histogram counts and bucket resolution when deriving percentiles; missing observations do not mean zero latency. These metrics do not establish performance acceptance by themselves.

-`RUSTFS_HEAL_ADAPTIVE_ADMISSION=true` enables Linux cgroup-v2 feedback shared by the heal manager’s four object-heal entry points and local Scanner namespace reads and object accounting.

This does not yet control the abandoned-child streaming list coordinator, bucket/format repair or physical devices, and it is not a replacement for existing worker, disk or byte budgets.
+`RUSTFS_HEAL_ADAPTIVE_ADMISSION=true` enables Linux cgroup-v2 feedback for the four object-heal entry points owned by the heal manager. It is off by default while full SSD performance acceptance is pending. Unsupported platforms reject an enabled setting. This does not yet control scanner walks, bucket/format repair or physical devices, and it is not a replacement for existing worker, disk or byte budgets.

 The node samples its effective CPU quota/cpuset, ancestor memory headroom, CPU usage/throttling and CPU/memory/I/O pressure once per second. Sampling uses one blocking worker at a time. Resource reads retain their real start/end times: reads spanning over 20 ms or older than one second after all inputs return cannot renew admission. Counter rates use both read brackets conservatively. The concurrency cap is at most the rounded-up effective CPU count and 256 scheduling units; existing operator limits still apply independently. At most 1% memory headroom blocks new work. This is a pressure safeguard, not a memory reservation or a claim that concurrent repair buffers fit in the remaining bytes.

 Each complete sample leases admission for three seconds. Missing resource caps block new work; missing or low-confidence feedback retains at most one maintenance unit. CPU use above 90%, throttling or pressure above 1% of elapsed time, memory headroom at most 10%, foreground errors/cancellations, a foreground queue or a comparable foreground p99 regression reduce concurrency immediately. Recovery requires CPU use at most 70%, throttling/stalls at most 0.1% of elapsed time, at least 20% memory headroom, fresh foreground evidence and actual successful work. The existing controller probes one additional unit only after eight consecutive healthy seconds and cooldown. Limits affect new admission and do not revoke active work.

-The Scanner captures the same node owner once per bucket walk. Directory open/refill, entry type and size lookup, and object accounting try admission before their first storage poll; each unit ends when its operation future finishes. On contention, local and remote coordinators suspend the same traversal, release the bucket cache lease, and join the shared FIFO queue. They reacquire the cache lease and verify both cache revisions before resuming. A changed cache rejects the suspended result. Cancellation also drops the queued request; the existing cycle budget still bounds the walk. This retains directory and recursion state while allowing Heal to advance at capacity one, without repeatedly replaying a partially classified directory.
-
-Calls without a coordinating cache lease retain immediate resource deferral and useful partial-cache handling. Existing remote single-session ownership and local-disk admission shares remain in force. Disabled admission creates no request channel. Enabled walks use one bounded channel, with a response allocation and cache revision reads only on contention; the uncontended per-entry path adds no global lookup or task. The streaming abandoned-child coordinator requires a separate ownership boundary: retaining a node unit while it waits for a bounded-channel consumer that needs the same unit would deadlock at capacity one.
-
 Foreground comparison uses the existing complete response-body windows and shared admission snapshots. Each active class needs at least 100 completions and a finite p99 interval; this permits the percentile rank but is not a statistical confidence guarantee. Comparisons require the same active classes and rates within 80–125% of a retained reference. A changed workload resets recovery. The reference is an observed workload window, not an independent background-off baseline. A p99 interval can justify stability only when its upper bound is within 5% of the reference lower bound; a lower bound above 105% of the reference upper bound is pressure. Overlapping/uncertain comparisons cannot justify growth. Missing queues, stale or repeated cuts, uncertain cut boundaries and low counts are not idle evidence.

-Heal admission waits at most 250 ms before returning the existing typed transient deferral, before polling storage or taking namespace locks. No-lock callers never wait. Queued read repair uses the same node gate; direct foreground ECStore calls remain outside this heal-manager adapter. Cancellation releases the non-cloneable node scheduling unit. Native work retains separate physical-I/O units, and unsuccessful/cancelled/dry-run work cannot increment the node's completed-work counter. This scheduling counter is not an authoritative heal receipt and cannot discharge repair responsibility.

 The `rustfs_background_node_admission_limit` and `rustfs_background_node_admission_active` gauges describe the last published sample, not a live reservation proof. A blocked sampler can leave these exports stale even though the admission lease has expired. Full disk-owner feedback, shared scanner scheduling, escaping-buffer byte ownership and the matched-release SSD matrix/hot-shrink/72-hour soak remain required before enabling this by default or claiming optimal performance.

-# Immutable validation candidates
-
-Canonical validation on the current auto-testing fleet consumes one exact
-package, source commit and candidate-bound tool build. A successful package
-build is provenance evidence, not a canonical test PASS.
-
-The scheduled Functional Chain continues to resolve successful Nightly GNU
-Build attempts from `main`. Optional manual validation can also resolve a
-validation package built without publishing nightly aliases or release assets.
-
-## Build a validation package
-
-Dispatch **RustFS Functional Chain** from the desired driver revision with
-only `validation_package_sha` set to the full 40-character RustFS source SHA.
-Keep candidate, case, helper, tools and cleanup inputs empty or false. The
-request validator rejects mixed package/fleet execution before building.
-
-The package job calls `rustfs-validation-package.yml`, checks out the requested
-source, confirms its Git SHA and builds the ordinary release binary and DEB.
-This job uses build runners and does not acquire or mutate the Heal fleet.
-The same workflow can be dispatched directly with its `source_sha` input when
-it is available on the repository's default branch.
-
-Publication requires complete R2 configuration, conditional `PutObject` with
-`If-None-Match: *`, and a public download whose SHA-256 matches the local DEB.
-Failure emits no candidate manifest. An existing object is never overwritten.
-The only object path is:
-
-```text
-artifacts/rustfs/packages/validation/runs/<run>/<attempt>/<package-sha256>/rustfs.deb
-```
-
-The schema-3 artifact `validation-candidate-<run>-<attempt>` records the
-workflow SHA independently of the exact source SHA and source ref, the
-`validation` channel, build run/attempt, immutable URL and package checksum.
-The resolver verifies the successful manual run, repository/workflow identity,
-exact artifact name and digest, archive members, schema and immutable URL.
-The ordinary scheduled chain does not enable validation package resolution.
-
-## Validate the candidate
-
-After the package run succeeds, dispatch Functional Chain with its exact
-`build_run_id` and `build_run_attempt`, a canonical `validation_case`, and an
-exact `auto_testing_sha`. Heal also requires a new tool build verified against
-that source and helper revision. Reassess source-bound contracts and native
-prerequisites when the source changes; an older tool artifact does not certify
-a new candidate.
-
-The fleet lane retains the shared environment lock, per-case evidence and
-cleanup gate. Record new results separately. A package build, native test,
-diagnostic replay, clean recovery or partial topology result cannot replace
