 Risk and review shape:
 
-- **Exempt:** documentation, comments, formatting, or typos with no runtime, build, test, or agent-execution effect.
-- **Mechanical:** changes shown to preserve behavior, such as a symbol rename with unchanged callers or a file move with equivalent wiring. Run correctness and simplicity lenses. Classify tests, tooling, CI, and agent instructions by the behavior and authority they change, not their file type; deleting regression protection or changing failure propagation, publishing, or destructive actions can be high risk.
-- **Standard:** localized behavior changes. Run one integrated final-diff pass covering correctness, simplicity, and test coverage; add only domain lenses matched by the diff.
-- **High risk / substantial PR review:** high risk includes locking, erasure/quorum/heal, replication, multipart, RPC, lifecycle/tiering, persistence/fsync, IAM/KMS/auth, cryptography, on-disk/on-wire formats, and S3-visible semantics. Cover the applicable lenses from two perspectives: first trace the intended contract and implementation, then independently challenge its assumptions, failure paths, and evidence. Use separate reviewers when delegation is authorized and useful, or fresh sequential passes otherwise. Choose staffing and split lenses to fit the risk; a fixed reviewer count or duplicated review is not the goal.
-- **Outbound client defaults:** what `TargetClient`, `PutObjectOptions`, or the remote SDK configuration sends to every replication or migration target is high risk for every target class even when the change fixes one. Follow the SOP in `docs/postmortems/2026-09-03-replication-checksum-default-regression.md`: run the outbound target matrix, document each new env knob in the same PR, and list verified and unverified target classes in the PR Impact section.

 # Implementation Rules
 
-These implementation, style, and quality rules apply to all contributions, regardless of author or editor. Paths below are repository-relative. Read only the relevant sections during read-only review; select verification from the root `AGENTS.md`.
-
-## Shared Style Contract
-
-- Use the toolchain declared in `rust-toolchain.toml`, respect the minimum supported Rust version in `Cargo.toml`, and let `rustfmt.toml` and the configured Rust/Clippy lints define mechanical style. Do not override repository settings with personal formatter or lint preferences.
-- Follow the owning module's organization, imports, and domain terminology where repository rules leave a choice. Existing violations do not justify new ones; avoid unrelated cleanup in a focused change.
-- Rules using "must" or "do not" are requirements. Rules using "prefer" are defaults; depart when correctness, ownership, performance, or readability benefits justify it. Explain consequential tradeoffs, not every idiomatic choice. Where several approaches meet the contract equally well, the implementer chooses.
-- Follow the declared toolchain locally and the affected CI lane's toolchain for reproduction. The repository currently tracks `stable`; for a formatter/lint mismatch, compare `rustc -Vv`, `cargo fmt --version`, and `cargo clippy --version` with the failing run before changing code. Toolchain upgrades must keep local and CI settings aligned and pass their affected gates; do not silently raise `rust-version` or change lint policy to make a check pass.
+Applies when changing code or running artifact-heavy work. Paths below
+are repository-relative. Read only the relevant sections during read-only review.
 
 ## Worktree and Disk Hygiene
 
-- For a new task, start from the latest `origin/main` unless a different base is requested, and confirm the requested change is not already present. When continuing existing work or a PR, preserve its branch, base, and task-owned changes; do not restart it from `main`.
-- An existing clean, isolated task worktree is sufficient. Create another worktree only when the current checkout is shared, dirty with unrelated work, or belongs to another task.

+  change is not already present.
+- An existing clean, isolated task worktree is sufficient. Create another
+  worktree only when the current checkout is shared, dirty with unrelated work,
+  or belongs to another task.
 - Never commit from a shared checkout.
-- Use a task-specific branch named `<type>/<topic>`, such as `fix/...`, `feat/...`, `test/...`, or `docs/...`, unless the user specifies a name.
-- Do not include agent, tool, contributor, account, or organization names in branch names.
-- Push to the user-requested remote or the repository's configured push remote. Do not hard-code or infer a remote from an account name.
-- Check free space before artifact-heavy builds, tests, coverage, or downloads. Re-check before a broad gate when space is tight.
-- Remove only task-owned temporary/build artifacts. Never delete another task's worktree or uncommitted data.
-- At handoff, mention disk or cleanup details only when they affected execution or artifacts/worktrees remain intentionally.
-- For Docker verification, ensure the tested image contains the intended binary. `buildx build` without `--load` leaves the image in the build cache; use the Makefile's loaded image and rebuild without cache only when stale artifacts are evidenced.
+- Use a task-specific branch named `<type>/<topic>`, such as `fix/...`,
+  `feat/...`, `test/...`, or `docs/...`, unless the user specifies a name.

+  or artifacts/worktrees remain intentionally.
 
 ## Change Style
 
-- Preserve unrelated control flow. Restructure touched code only when needed for the requested behavior or an explicitly requested refactor; style preferences alone do not justify changing execution order or cleanup behavior.
-- Prefer a direct local edit over new files, wrappers, managers, or speculative abstractions.
-- Add a helper only when it removes current duplication, names a real domain boundary, or isolates a non-trivial invariant. Keep helpers near the code they support when the module's organization permits it.
-- Remove an in-scope path superseded by the change. If compatibility requires it, adapt at the boundary to one canonical core and use the repository's `RUSTFS_COMPAT_TODO` policy.
-- Comments explain non-obvious invariants or reasons. Do not narrate code or record change history.

 - Mention unrelated problems when useful; do not fix them in a narrow task.
 
-## Rust Style
-
-These repository-owned rules incorporate selected ideas from the [OpenCode style guide](https://github.com/anomalyco/opencode/blob/dev/AGENTS.md#style-guide), adapted to RustFS. That link is background, not an additional rule source. Apply these defaults to new or changed code; correctness and domain invariants take priority.
-
-- Default to immutable `let` bindings; use `mut` for actual state changes. Prefer `if` or `match` expressions when branches compute a value instead of initializing a placeholder and reassigning it.
-- Use type inference for obvious local values. Add annotations when inference needs help or the numeric, collection, or error type matters to understanding the code. Keep explicit types in function signatures and public contracts.
-- Keep the main path readable with guard clauses, `let ... else`, and `?` when immediate propagation is correct. Preserve explicit handling for recovery, cleanup, aggregation, and quorum decisions; `if`/`else` expressions and exhaustive `match` remain idiomatic.
-- Prefer readable iterator chains for straightforward mapping and filtering. Keep loops when they make state changes, early exits, or async operations clearer. Do not add intermediate collections or clones just to use iterators.
-- Inline trivial single-use expressions only when a binding adds no meaning. Keep names that explain domain concepts, aid debugging, or make ownership and guard lifetimes clear. Do not change lock release or drop timing for style.
-- Keep pure parsing, validation, and option-building helpers synchronous unless an async interface contract requires otherwise. This does not make blocking I/O or CPU-heavy work safe to run on async executor threads; offload it when needed to keep those threads responsive.
-
 ## Reuse and Boundary Rules
 
-- Before adding helpers, constants, fixtures, or wrappers, search the touched code and domain owner; check `crates/utils`, `crates/common`, and direct dependencies when they could own the behavior. Stop once the relevant reuse boundary is clear.
-- Reuse requires matching semantics: normalization, error types, deadlines, durability, and compatibility must fit the call site. A narrowly named local helper is better than forced reuse with different semantics.
-- Validate untrusted input at the boundary that owns it, then pass validated types inward without repeating checks whose guarantees still hold. Deserializing into a Rust type alone does not establish domain validity. Values newly read from disk, RPC, persistence, or another version must be validated at that consuming boundary.
-- For destructive actions such as delete or overwrite and for quorum decisions, check the relevant identity, generation, and authority under the operation's existing synchronization or precondition contract. A separate unguarded recheck does not prevent a check/use race.
-- Every new control-flow branch needs a concrete triggering input/state. For decoded or peer data, corruption and mixed-version input are valid triggers.
-- Required values must return a typed error when absent or corrupt; do not use a default that converts corruption into a plausible result.
-- Attach error context once where it is actionable. Do not erase typed errors below aggregation or quorum layers.
+- Before adding helpers, constants, fixtures, or wrappers, search the touched
+  crate, the domain-owning crate, `crates/utils`, `crates/common`, and relevant
+  direct dependencies.
+- Reuse requires matching semantics: normalization, error types, deadlines,
+  durability, and compatibility must fit the call site. A narrowly named local
+  helper is better than forced reuse with different semantics.
+- Validate untrusted input at its trust boundary, then trust the validated type.
+  Values crossing disk, RPC, persistence, or version boundaries remain
+  untrusted at every consumer.
+- Re-check boundary values immediately before destructive actions such as
+  delete, overwrite, or quorum decisions.
+- Every new branch needs a concrete triggering input/state. For decoded or peer
+  data, corruption and mixed-version input are valid triggers.
+- Required values must return a typed error when absent or corrupt; do not use a
+  default that converts corruption into a plausible result.
+- Attach error context once where it is actionable. Do not erase typed errors
+  below aggregation or quorum layers.
 
 ## Rust Boundaries
 
-- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees. Stricter scoped prohibitions, including `crates/AGENTS.md`, still apply. Invalid client, disk, or peer data must return errors rather than trigger panics.
+- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees.
 - Public APIs do not return `Result<_, String>`. Library APIs use domain errors unless intentional erasure is part of the boundary contract; expose a stored inner error through `Error::source()`.
 - Numeric conversions must not silently truncate. Use fallible conversions for untrusted values; validate finiteness, sign, and range before float-to-integer conversion. Clamp/saturate only when required by the domain.
 - Do not add crate-root `#![allow(dead_code)]`.
 
 ## Naming
 
-Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case` functions/variables/modules, and `PascalCase` types/traits. Name domain concepts and include units where a value would otherwise be ambiguous; do not optimize for short names. Do not rename public, serialized, or persisted fields merely to match a local style preference, or rename unrelated existing violations.
-
-## API and Operational Contracts
-
-- For new or changed public APIs, document the caller-visible behavior and relevant `# Errors`, `# Panics`, and `# Safety` conditions. Include a useful example or link to one when usage is non-obvious; avoid boilerplate sections that say nothing. Follow the [Rust API documentation guidelines](https://rust-lang.github.io/api-guidelines/documentation.html) within the scope of the change.
-- For async or storage APIs, state cancellation, retry/idempotency, partial-completion, ownership, and durability guarantees when callers rely on them. Make failure cleanup and commit points explicit in code and tests; do not imply atomicity that the implementation does not provide.
-- For protocol, persisted-format, configuration, dependency, or operational changes, check affected consumers and supported versions. Update relevant docs/examples and describe compatibility, upgrade/rollback limits, and new configuration defaults when they change. New dependencies must solve a current need and fit the workspace's license, toolchain, and feature policy.
-- For hot-path or resource-management changes, check allocation/copying, blocking, unbounded work, and lock duration where affected. Support performance claims with an appropriate measurement or clearly label them as expectations; a benchmark is not required for unrelated changes.
-
-## Behavioral Tests
-
-- For behavior changes, add or update the narrowest test that calls the real implementation and asserts an observable result. Existing tests can provide coverage when they directly exercise the changed behavior; do not duplicate production logic as the test oracle.
-- Cover the changed contract's relevant failure and boundary cases, not only success. A bug regression should fail without the fix; do not broaden assertions or rely only on a successful call when the result or side effect is what matters.
-- Follow `docs/testing/README.md` for test layers, runners, isolation, synchronization, and flaky tests. Use controlled clocks or explicit synchronization for time/concurrency tests instead of fixed sleeps, and keep waits bounded.
-- Report the checks actually run and their outcomes, including skipped or blocked checks and the behavior they leave unverified. Do not describe focused local checks as full CI coverage.
+Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case`
+functions/variables, and `PascalCase` types. Do not rename unrelated existing
+violations.

 ## Final PR Preflight
 
 Before creating or updating a PR, reuse completed review and verification:
 
-- Verify the actual base (normally `origin/main`) and the complete task diff, including file names and whitespace. Exclude secrets, logs, generated artifacts, and unrelated edits. Retain an existing PR's base unless requested.
-- Confirm the final diff passed the root verification tier; fix task-owned failures and run missing scoped checks. Report unresolved required checks or authority without expanding the task. Do not start another general review.
-- Keep the English Conventional Commit title at most 72 characters. Use the template headings, actual checks, material risks, and rollback notes.
-- Immediately before writing to GitHub, confirm the head and task diff are unchanged. Rerun only checks invalidated by edits or relevant state changes.

When authorized, fix task-attributable issues, rerun affected verification, and resume the requested monitor. Otherwise report the concrete failure and next action without expanding scope.
-- Merge only with existing user authorization and satisfied applicable reviewer, check, and branch-protection requirements. Reviewer approval does not grant merge authority; user authorization does not bypass repository protections.
-- After an observed merge, verify the commit reached the base, then clean the task worktree/branch when safe. Preserve unmerged work for closed PRs unless deletion was explicitly authorized.

+   naming the attacks performed.
+4. Apply root `AGENTS.md`'s finding standard. Test each candidate against callers,
+   existing coverage, and invariants before accepting it; an adversarial role
+   does not have to produce a defect.
+5. Fix or rebut supported findings with code-path, test, or invariant evidence.
+6. After a non-trivial edit, rerun only lenses affected by that edit against the
+   new exact diff.
+
+Do not turn a null verdict into a long checklist. Record concise evidence that
+the relevant failure classes were attacked, then stop under the root completion
+rule. Keep the required per-lens verdicts for high-risk PRs.

+# Compatibility Lens
+
+- Internal metadata uses `metadata_compat` helpers for dual RustFS/MinIO keys,
+  including mixed casing and removal of both twins.
+- Binary UUID metadata treats absent, empty, and nil as no value. Unversioned
+  remote tiers receive no `versionId`; versioned purge requests retain the real
+  version ID.
+- `xl.meta` changes preserve supported header/meta versions, recompute
+  signatures, decode legacy fixtures, and remain readable by old RustFS/MinIO.
+- Foreign/corrupt metadata validates parallel array lengths and missing fields;
+  it returns a decode error rather than indexing, panicking, or fabricating data.
+- Do not “correct” byte-for-byte MinIO ports without legacy fixture evidence.
+  Bitrot framing, shard math, distribution, and inline prefixes are contracts.
+- Client-visible metadata/events strip both internal prefixes
+  case-insensitively.
+- Proto fields are appended, never reused/renumbered; FlatBuffers tables extend
+  compatibly and absent new fields fail closed where authorization/quorum is
+  involved.
+- Replay real client request shapes and exact pagination boundaries for S3
+  handler changes.
+- Bucket metadata/IAM/config parsing remains compatible with pinned real MinIO
+  fixtures and encrypted migration data.
+- Compatibility shims use `RUSTFS_COMPAT_TODO(<task-id>)`, have a removal
+  condition, and default toward reading old data safely.
+
+## Outbound targets
+
+- A change to what the replication or migration client sends by default
+  (checksum policy, payload framing, headers, version-id addressing) is judged
+  against every target class, not the one it fixes. Name each target-side rule
+  the current default satisfies — checksum required with Object Lock
+  parameters, `aws-chunked` decoding, version-id adoption, ETag equals content
+  MD5 — and show which cell of
+  `crates/e2e_test/src/replication_target_matrix_test.rs` covers each.
+- A test that asserts the fix ("no trailer header") is not evidence; the
+  matrix cell that asserts the target accepted and stored the object is.
+- Every new environment escape hatch appears in
+  `docs/operations/replication-outbound-transport.md` in the same diff.

+# Concurrency and Durability Lens

+- For every changed lock, enumerate overlapping lock sets and construct the
+  ABBA interleaving. Multiple-lock order must be documented and consistent.
+- Mark guard lifetimes and every `.await`, disk,
+  and RPC call; estimate contention/timeouts. Tokio read/write guards across
+  `.await` need bounded hold time; long-lived reads can wedge writers (#4195).
+  Keep `std::sync::Mutex` holds brief and never across `.await`.
+- Use direct `fetch_*` for unconditional atomic read-modify-write and
+  `compare_exchange` for conditional updates.
+- Object commits remain fenced if the distributed lock is lost after shard
+  writes and before metadata rename.
+- For write/rename changes, trace `write tmp -> sync tmp -> rename -> sync parent
+  -> sync required ancestors`; simulate a crash after each step and honor the
+  configured durability gate.
+- Multi-disk fan-out counts every result. Quorum-minus-one cannot become success;
+  heal remains best-effort per target where that is the established contract.
+- At every new cancellable await between mutation and cleanup/commit, drop the
+  future and inspect leftover files, counters, permits, and replay state.
+- Multipart operations on the same upload ID are serialized where required;
+  abort/complete/list races cannot delete parts before durable commit.
+- Post-commit cleanup is best-effort, retry-safe, and cannot fail an already
+  committed write or delete the last surviving copy.
+- Persisted read-modify-write uses serialization/CAS. Queue replay is crash-safe
+  and duplicate delivery has an idempotency contract.

+- Paths/object/archive entries: reject traversal, absolute/platform escapes,

+- Copy/multipart/presigned POST: enforce source, destination, version-aware

+- Logging/errors: never expose credentials, tokens, expected signatures, raw

+- Untrusted serde: reject unknown fields where compatible and validate

+- Object Lock: unreadable/fabricated/unparsable metadata fails closed across

-## Security Advisories
-
-Reconcile advisories after every completed final release, including Console-only releases. Read-only preparation may start earlier; do not claim an unpublished artifact is an available fix.
-
-1. Fetch every page of the repository's live Security Advisories, including triage, draft, published, and closed states. A permission error or partial response blocks reconciliation; it does not mean there are no advisories. Keep unpublished advisory details in private task artifacts, never in a public PR, release note, or issue.
-2. For each potentially relevant advisory, map its fix to the exact published tag and verify the regression evidence. Main-branch reachability, a merged private fix, or a green build alone does not prove the shipped version is fixed. Check cherry-picked equivalents and reverted fixes explicitly. For embedded Console or dependency fixes, verify the shipped component version.
-3. Determine the first available fixed release and affected version ranges from evidence. Preserve an earlier correct patched version; do not relabel all fixes as the current release. An unchanged server baseline such as a Console-only release requires checking the earlier server release as well. Leave unresolved reports and fixes absent from the tag pending; do not close them merely because a release shipped.
-4. Prepare any necessary corrections to package identity, affected ranges, patched versions, fix/release links, and advisory text. Preserve unrelated fields, credit, CVE identifiers, and disclosure coordination. Apply updates only within existing user authorization; read back the result to verify it. Publishing a draft, requesting a CVE, or closing a report is a separate action: require explicit authorization for the concrete advisories and respect any embargo. Release-tag approval alone does not authorize those actions. Prepare the exact proposed changes before asking for missing authorization.
-5. Record each relevant advisory's URL, current state, fix evidence, first fixed version, action taken or proposed, and remaining blocker in private task artifacts. Report advisory follow-up separately from artifact publication. A successful release with unresolved advisory work is not complete follow-up; retain that work for the release monitor or a concrete user decision.

-## Reconcile main and remove the completed release branch
-
-1. Compare the exact published tag with current main. Audit every release-side commit since their merge base, including inherited backports. An ahead count is a history difference, not proof of missing changes. Use ancestry and patch equivalence, then inspect current code and regression evidence for squashed, adapted, superseded, or reverted changes. Record each commit as present, superseded, release-only, or missing; a positive `git cherry` result alone does not prove a missing fix.
-2. Bring missing shared changes to main through a reviewed PR and the required checks before closing the follow-up. Preserve main's later changes; decide version bumps and pinned Console configuration separately. If a history merge is needed, use a merge commit and verify the release commit is an ancestor of main; squash does not establish that ancestry. Do not merge main into the published release branch or move its tags. Report unresolved changes instead of claiming reconciliation is complete.
-3. After publication and authorized follow-ups are complete, delete the remote `release/<target>` branch. Immediately before deletion, verify its HEAD still equals the published tag's commit and no open PR targets or originates from it. Preserve a branch with newer work or open PRs and report the blocker. Use a deletion with an expected-old-SHA check to avoid removing a concurrently advanced branch.
-4. Verify the remote branch is absent and the final and preview tags still resolve to their recorded commits. Remove a local release branch only if it is task-owned, unchecked out, and has no unpreserved work.

 ## Phase 4 — Run the artifact locally, verify the console
 
-Use a unique task-owned scratch directory. Select the versioned archive matching the host OS, architecture, and runtime, download its checksum file, and verify the archive before extraction. Do not substitute a different build when a matching artifact is unavailable; report that acceptance gap. The shell example below assumes the verified executable is at `RUSTFS_BINARY` (`rustfs.exe` on Windows), `SCRATCH` is the task directory, and `S3_PORT` and `CONSOLE_PORT` are distinct available ports. Use equivalent native commands when the shell differs.
-
-Bind both listeners to loopback. Choose task-only credentials, set loopback proxy exclusions for the server/client processes, and record the server PID. A port probe does not reserve a port; retry startup with fresh ports on a bind conflict rather than connecting to an existing service.
+Work inside the session scratchpad directory; never leave stray data dirs.

 Checks (all must pass):
 
-- `"$RUSTFS_BINARY" --version` reports the preview tag name and the short SHA of `PREVIEW_HASH`. Reporting `<target>` without the `-preview.N` suffix means the build did not embed the tag — treat as FAIL and investigate before proceeding.
-- Wait with a bounded readiness deadline while checking the recorded server process remains alive; `curl --noproxy '*' -fsS "$S3_ENDPOINT/health/ready"` must return ready from this process's listener.
+- `./rustfs --version` reports the preview tag name and the short SHA of `PREVIEW_HASH`. Reporting `<target>` without the `-preview.N` suffix means the build did not embed the tag — treat as FAIL and investigate before proceeding.
+- `curl -fsS http://localhost:9000/health/ready` returns ready.
 - Startup log shows the embedded console being served (this was the regression that `fix(release): require embedded console assets` guards).
-- Open `CONSOLE_ENDPOINT` in the browser and log in with the task credentials. The dashboard must render without JS console errors; create a bucket, upload a file, download it back (byte-identical), and delete the object and bucket. Keep the server running for Phase 5.
+- Open `http://localhost:9001` in the browser: login with `rustfsadmin`/`rustfsadmin`; dashboard renders without JS console errors; create a bucket, upload a file, download it back (byte-identical), delete the object and bucket. Keep the server running for Phase 5.
 
 ## Phase 5 — Validate with the latest rc client
 
 `rc` is the RustFS CLI client from <https://github.com/rustfs/cli>.
 
-- Resolve the latest release with `gh api repos/rustfs/cli/releases/latest --jq .tag_name`; verify the local client's version or download and verify a host-compatible client into the task directory. Set `RC_BIN` to that executable and record its version/digest. Avoid changing the user's installed client for this check.
-- Inspect the client's current help for an isolated configuration option and use it when supported. Otherwise choose a unique `PREVIEW_ALIAS` and confirm it is absent before creating it; never overwrite an existing alias. Use task-owned bucket/user names and input/output files. The names below are safe only inside the newly started isolated server.
-- Point the client at `S3_ENDPOINT` with loopback proxy exclusions and run the command matrix, recording PASS/FAIL per command:
+- Ensure the latest release is installed: compare `rc --version` against `gh api repos/rustfs/cli/releases/latest --jq .tag_name`; update via `brew upgrade rustfs/tap/rc` (or download the release binary).
+- Point it at the preview server and run the command matrix, recording PASS/FAIL per command:

Retain available toolchain and build provenance with the artifact checksums; the same source SHA alone does not establish equivalent builds.

+# RustFS Security Advisory Lessons
+
+Use this skill as the deep security lens. For a normal adversarial review with a
+matched security surface, the concise security reference under
+`adversarial-validation` is sufficient.
+
+## Workflow
+
+1. Freeze the exact diff/head and identify the changed trust boundaries.
+2. Inspect the headings in [advisory-patterns.md](references/advisory-patterns.md),
+   then read the matching sections. Read the full map only for a broad security
+   audit. Useful headings are
+   auth/admin, IAM/STS/OIDC, policy/plugins, S3/copy/multipart, protocols, paths,
+   secrets/logging/RPC, browser/CORS/proxy, SSE, Object Lock, and serde.
+3. Trace unauthenticated, low-privilege, wrong-action/owner/bucket, malformed,
+   and default-config cases. Security decisions must fail closed.
+4. Require a focused negative regression test for the bypass/exploit form, not
+   only the intended success path. State residual risk when a test is impractical.
+5. Report proven vulnerabilities separately from defense-in-depth hardening.
+
+When advisory currentness matters, fetch the live inventory instead of treating
+the reference as a status mirror:
+
+```bash
+gh api repos/rustfs/rustfs/security-advisories --paginate \
+  --jq '.[] | {ghsa_id,state,severity,summary,updated_at}'
+```
+
+Fetch an individual advisory only when the live summary indicates a new or
+changed lesson.
+
+## Finding Standard
+
+Each finding includes severity, `file:line`, attacker prerequisites, concrete
+input/path, impact, smallest safe fix, and a regression check. Do not exaggerate
+unauthenticated impact when the actual issue requires authenticated low privilege.

+
+## Pattern Index
+
+### Admin authorization and route exposure
+
+- `GHSA-pfcq-4gjr-6gjm`: notification target endpoints accepted authenticated users but skipped admin authorization. Lesson: distinguish authn from authz; admin target CRUD must call the operation-specific admin authorization path.
+- `GHSA-mm2q-qcmx-gw4w`: `ListServiceAccount` used `UpdateServiceAccountAdminAction`, while update lacked target ownership checks. Lesson: exact action constants and ownership checks are both required; information disclosure can chain into secret rotation and takeover.
+- `GHSA-vcwh-pff9-64cc`: `ImportIam` checked `ExportIAMAction` for an import/write operation. Lesson: every admin handler must authorize the action it actually performs.
+- `GHSA-jqmc-mg33-v45g` and `GHSA-8784-9m7f-c6p6`: `/profile/cpu` and `/profile/memory` were whitelisted from auth and allowed expensive diagnostics plus path disclosure. Lesson: profiling/debug endpoints need admin auth, opt-in, rate limits, and non-sensitive responses.
+- `GHSA-f5cv-v44x-2xgf`: `/rustfs/admin/v3/metrics` accepted any authenticated IAM user and skipped admin authorization. Lesson: read-only metrics and diagnostic admin endpoints still require an operation-specific admin action check.
+- `GHSA-796f-j7xp-hwf4`: `/rustfs/admin/v3/list-remote-targets` checked only that credentials existed and leaked replication target credentials. Lesson: replication target reads are privileged admin operations, and stored remote credentials require strict authz plus response redaction review.
+- `GHSA-xp32-gxq2-3v52`: console license metadata endpoint was public and exposed subject and expiration fields. Lesson: management metadata endpoints should require admin auth or return only coarse public status.
+
+### IAM import, service accounts, and privilege boundaries
+
+- `GHSA-566f-q62r-wcr8`: `ImportIam` accepted attacker-controlled service account `parent`, `claims`, `accessKey`, and `secretKey`, enabling persistent backdoor accounts under root. Lesson: imported IAM payloads are untrusted data and must be validated against privilege boundaries.
+- `GHSA-3495-h8r9-gfqg`: `ExportIAM` wrote regular-user and service-account secret keys into exported ZIP data. Lesson: IAM export is a credential-disclosure boundary; redact, seal, or strictly justify every exported secret before treating export permission as safe.
+- `GHSA-5354-r3w2-34m8`: `AddServiceAccount` checked `CreateServiceAccountAdminAction` but trusted caller-supplied `target_user`, allowing service accounts under the root parent. Lesson: service-account create paths must validate parent ownership or root/admin authority, not only the create action.
+- `GHSA-xgr5-qc6w-vcg9`: `deny_only=true` skipped allow checks and let restricted service accounts mint unrestricted children. Lesson: deny-only logic must never become implicit allow for privilege creation.
+- `GHSA-mm2q-qcmx-gw4w`: leaked service account access keys plus update-without-ownership formed an escalation chain. Lesson: service-account identifiers are security-sensitive because update APIs consume them.
+
+### STS, OIDC, and federation flows
+
+- `GHSA-5qfg-mf7r-jp3w` and `GHSA-3473-5353-xhwh`: `AssumeRoleWithWebIdentity` was reachable through unauthenticated `POST /` routing and could issue temporary credentials from crafted web identity input. Lesson: every STS route needs explicit SigV4 or trusted identity-provider validation before role assumption, and unauthenticated exemptions must be narrowed to the exact action with uniform failure responses.
+- `GHSA-jxrr-r6pv-h958`: unsigned JWT issuer data was decoded before verification to select an OIDC provider, and distinguishable failures could expose provider configuration. Lesson: web-identity routing may be unauthenticated, but pre-verification claims are untrusted routing hints; bound and rate-limit the request, normalize public errors, and verify signature, issuer, audience, and expiration before issuing credentials.
+- `GHSA-ccrv-v8v9-ch9q`, `GHSA-48rf-7j3q-3hfv`, and `GHSA-xvfh-7c9g-hpw2`: service-account-controlled material could self-sign JWT session tokens with forged policy claims, and missing `exp` was accepted for service-account tokens. Lesson: session tokens must be signed by a trusted issuer/key path, enforce required claims and expiration, and reject self-signed or principal-controlled tokens.
+- `GHSA-9pjf-w3c2-m32r`, `GHSA-4x2q-cpx9-9h26`, and `GHSA-xvpm-p3f7-34c3`: public OIDC authorize/callback flows trusted request `Host` or forwarded scheme when building credential-bearing redirects. Lesson: OIDC redirects must use configured allowlisted origins and trusted-proxy handling; never derive the post-login credential destination from direct client headers.
+- `GHSA-m479-9x88-94w6`, `GHSA-frwq-mfqx-83p8`, `GHSA-q9q8-rf9r-fg9f`, and `GHSA-j5c2-hhf7-6gf5`: OIDC validation accepted attacker-controlled discovery URLs because hostname checks rejected only literal forbidden IPs, allowing DNS rebinding SSRF. Lesson: outbound federation URL validation must resolve and classify hostnames at the connection boundary and reject loopback, private, link-local, and rebound addresses.
+
+### IAM policy conditions and external policy plugins
+
+- `GHSA-6r96-hmgc-726c`: request headers collided with lowercase server-derived condition keys such as `userid`, `groups`, `versionid`, and JWT/LDAP claims. Lesson: never let caller-controlled headers append to or replace server-derived policy context; reserve trusted condition keys and keep intentional request-header keys separate.
+- `GHSA-v9cp-qfw9-9pfp`: quantified negated string conditions applied negation after aggregation, transposing `ForAllValues` and `ForAnyValue` semantics. Lesson: push negation into the per-value predicate for quantified operators and test partially overlapping multi-value sets.
+- `GHSA-5w8r-p896-6vq2`: OPA policy mode skipped `ExistingObjectTag/*` loading, so tagged objects looked untagged to external policies. Lesson: external authorization plugins need the same object-tag and request context as built-in policy evaluation before they decide.
+
+### S3 object actions, copy, multipart, and upload policy validation
+
+- `GHSA-g8w9-qw9q-fghr` and `GHSA-xm99-m3gq-83g8`: a valid presigned `PutObject` accepted extra `x-amz-*` headers omitted from `SignedHeaders`; `x-amz-copy-source` could turn that upload capability into a cross-bucket read performed as the signer. Lesson: a presigned URL is a bounded capability; inspect all received security-sensitive headers and reject unsigned ones before selecting the S3 operation or reaching storage.
+- `GHSA-3ppv-fx5m-m749`: explicit `versionId` reads and copy sources authorized `s3:GetObject` instead of `s3:GetObjectVersion`. Lesson: version-specific object access must select version-specific actions for direct reads, `CopyObject`, and `UploadPartCopy`, with tests proving the backend is not reached on denial.
+- `GHSA-gjph-xcgw-4p7w`: `PutObject` and browser POST accepted a caller-supplied `versionId` and replaced an unlocked historical version with only `s3:PutObject`. Lesson: only replication-authorized writes may choose an existing version ID; ordinary uploads must not rewrite version history.
+- `GHSA-x298-9x87-fvjq`: anonymous `ListObjectVersions` fell back to `ListBucket` and returned before public-access-block gates. Lesson: compatibility fallbacks must converge on the same post-authorization checks as direct grants, especially `RestrictPublicBuckets` and anonymous data-plane denies.
+- `GHSA-mx42-j6wv-px98`: `UploadPartCopy` missed source authorization and allowed cross-bucket object exfiltration. Lesson: multipart copy must enforce the same source and destination contract as `CopyObject`.
+- `GHSA-wfxj-ph3v-7mjf`: `UploadPartCopy` checked source and destination independently but missed destination copy-source policy constraints. Lesson: source read and destination write checks are not sufficient when policy constrains allowed copy sources.
+- `GHSA-w5fh-f8xh-5x3p`: presigned POST accepted uploads without enforcing signed policy conditions. Lesson: parse and enforce all POST policy constraints server-side, including size, key prefix, and content type.
+
+### Protocol frontends and IAM parity
+
+- `GHSA-3g29-xff2-92vp`: FTP `RETR` and `SIZE`/`MDTM` read paths authenticated the user but skipped IAM before calling storage. Lesson: non-HTTP protocol frontends must enforce the same per-operation authorization as the S3 API before backend access.
+- `GHSA-g3vq-vv42-f647`: FTPS `MKD` called `create_bucket` without checking `s3:CreateBucket`. Lesson: protocol command handlers need action-specific checks even when sibling handlers already authorize correctly.
+- `GHSA-3p3x-734c-h5vx`: FTPS and WebDAV compared secret keys with early-return string equality, while FTPS also returned distinguishable invalid-user and invalid-password failures. Lesson: password-style protocol auth needs constant-time secret comparison, indistinguishable failures where practical, and rate limiting.
+- `GHSA-rhg6-jrf2-29c4`: WebDAV, FTP/FTPS, and SFTP used identity-policy checks with empty conditions and bypassed S3 bucket-policy explicit denies and condition-key denies. Lesson: alternate listeners must evaluate the same effective policy and trustworthy request context before storage access.
+
+### Filesystem paths and object key traversal
+
+- `GHSA-pq29-69jg-9mxc`: RPC `read_file_stream` joined untrusted paths under a volume directory without canonical boundary checks. Lesson: `PathBuf::join` plus length checks are not path security.
+- `GHSA-8r6f-hmq2-28rg`: object keys containing traversal sequences bypassed bucket/object authorization when mapped to filesystem paths. Lesson: reject traversal at object-key parsing and verify final storage paths remain under the expected bucket/key root.
+- `GHSA-f4vq-9ffr-m8m3`: Snowball auto-extract accepted archive entries such as `../victim-bucket/object`, authorized the raw attacker-bucket path, then storage path cleaning crossed bucket boundaries. Lesson: archive entries become object keys and need traversal rejection plus consistent authz/storage normalization before writes.
+- `GHSA-g7fq-6xjm-mxf4`: versioned `DeleteObjects` accepted dot-segment keys, authorized the literal prefix, then wrote delete markers under a resolved sibling prefix. Lesson: validate each batch key before authorization and storage normalization, using the same object-name rules as single delete.
+
+### Secrets, defaults, and cryptographic misuse
+
+- `GHSA-j59h-h7q5-q348`, `GHSA-3wm5-wpm5-hmfm`, `GHSA-6wc8-xm48-qhmx`, `GHSA-9gf3-jx4p-4xxf`, `GHSA-63xc-c3w3-m2cf`, and `GHSA-ch63-6q4v-hwp5`: RustFS shipped known default root credentials that could authenticate to S3, admin APIs, IAM, KMS, console, and token-signing surfaces. Lesson: root credentials must be operator-provided or generated per install; known defaults and warnings are not acceptable for network-reachable deployments.
+- `GHSA-h956-rh7x-ppgj`: gRPC used the hard-coded token `rustfs rpc` on both client and server. Lesson: source-visible shared tokens are authentication bypasses.
+- `GHSA-r5qv-rc46-hv8q`: internode RPC HMAC secret fell back to the public default `rustfsadmin`. Lesson: RPC/internode auth must fail closed instead of silently using public defaults.
+- `GHSA-75fx-qg6f-8rm7` and `GHSA-68cw-96m3-h2cf`: internode RPC secrets were derivable from known root credentials, making raw storage RPC signatures forgeable when explicit RPC secrets were unset. Lesson: RPC auth keys must be independent random secrets, never derived from S3 root credentials, and raw storage RPC should not share the public S3 listener without an internode-only boundary.
+- `GHSA-m77q-r63m-pj89`: STS JWTs used the root secret key as the shared token signing key, allowing token forgery when the root secret was known. Lesson: STS signing keys need key separation, rotation, and key IDs; do not reuse root credentials for JWT/HMAC signing.
+- `GHSA-923g-jp7v-f97f`: license verification embedded a production RSA private key and used private-key decryption as authenticity. Lesson: ship verifying/public keys only and use real signature verification.
+
+### Sensitive logging and debug output
+
+- `GHSA-r54g-49rx-98cr`: STS credentials were logged at info level. Lesson: generated credentials must never be logged in plaintext.
+- `GHSA-8cm2-h255-v749`: debug logs leaked session tokens, secret keys, JWT claims, and raw STS response bodies. Lesson: redaction must cover custom `Debug` implementations and dependency response-body logging.
+- `GHSA-333v-68xh-8mmq`: invalid RPC signature logging included the shared HMAC secret and expected signature. Lesson: error paths often leak secrets; never log raw secrets or derived authenticators.
+
+### RPC input validation and panic safety
+
+- `GHSA-gw2x-q739-qhcr`: malformed gRPC `GetMetrics` payloads reached `unwrap()` on deserialization and caused remote DoS. Lesson: every network/RPC deserialization failure returns an error, not a panic.
+- `GHSA-h956-rh7x-ppgj` and `GHSA-r5qv-rc46-hv8q`: weak RPC auth increased reachability of otherwise internal handlers. Lesson: panic bugs become more severe when internode auth is weak or defaulted.
+- `GHSA-c667-rgrv-99vj`: NodeService authentication signed the service prefix instead of the concrete generated method path, so valid metadata for one RPC could be replayed to another method during the timestamp window. Lesson: RPC HMAC payloads must bind exact gRPC method path, HTTP method surrogate, timestamp, and secret.
+
+### Browser, CORS, and console isolation
+
+- `GHSA-v9fg-3cr2-277j`: object preview rendered attacker-controlled HTML in a same-origin iframe, exposing console credentials stored in `localStorage`. Lesson: user content must be origin-isolated from the console and protected with `nosniff`, CSP, and strict content-type handling.
+- `GHSA-7gcx-wg4x-q9x6`: an incomplete preview fix reintroduced extension-based PDF detection and bypassed the sandboxed fallback for attacker-controlled content. Lesson: browser-surface fixes need regression tests for alternate viewers and file-type branches, and preview trust must come from validated content type plus sandboxing rather than object names.
+- `GHSA-x5xv-223c-8vm7`: default CORS reflected arbitrary origins with credentials. Lesson: never combine reflected origins with `Access-Control-Allow-Credentials: true`; default should be fail-closed.
+
+### Trusted proxy and source IP conditions
+
+- `GHSA-fc6g-2gcp-2qrq`: `aws:SourceIp` trusted client-supplied `X-Forwarded-For` or `X-Real-IP`. Lesson: forwarded IP headers are valid only behind configured trusted proxies; direct clients use socket peer IP.
+
+### SSE and on-disk storage invariants
+
+- `GHSA-xrrf-67jm-3c2r`: SSE metadata reported encryption while reader composition bypassed `EncryptReader` and stored plaintext. Lesson: test actual bytes on disk and wrapper order, not only API metadata.
+- `GHSA-wqmc-vjgv-jrpw`: SSE-C persisted and listed the plaintext MD5 as the ETag, allowing list-only users to confirm or brute-force low-entropy content and correlate equal plaintext across keys. Lesson: encrypted-object ETags must not expose deterministic plaintext fingerprints; protect them with per-object key material and keep listing, conditional, copy, and multipart semantics consistent.
+
+### Object Lock and retention invariants
+
+- `GHSA-j548-9grx-fh4f`: Object Lock enforcement treated unreadable, fabricated, or unparsable bucket metadata as absent configuration and allowed retained objects to be deleted or expired. Lesson: retention must fail closed unless Object Lock absence is authoritative, and every delete, lifecycle, scanner, force-delete, and default-retention path needs the same state distinction.
+- `GHSA-28w4-rp2p-636w` and `GHSA-c7hx-vr97-45rg`: an authorized `DeleteBucket` with `x-rustfs-force-delete: true` removed active COMPLIANCE-retained versions even though ordinary version deletion was denied. Lesson: bucket force-delete must enforce retention across every version, including against root/owner callers.
+
+### Serde deserialization and input validation
+
+- Reject unknown fields in untrusted S3 API XML/JSON, lifecycle, policy, and replication input where compatibility permits. Check the current type and supported payload fixtures; do not infer the repository's current coverage from an older audit. Where extra fields are part of the compatibility contract, validate security-critical values explicitly.
+- `#[serde(default)]` on security-critical fields silently accepts missing values as zero/empty. Lesson: when a field has security implications (retention days, permissions, limits), validate the deserialized value explicitly rather than relying on defaults.
+- Integer fields deserialized from user input and cast with `as` (e.g., `i32 as u32`) can wrap negative values to large positives. Lesson: validate ranges before casting; use `try_into()` with a typed error, or clamp only when the domain explicitly requires saturation.
+- XML config typos (e.g., `"NoncurentDays"` instead of `"NoncurrentDays"`) are silently accepted when `deny_unknown_fields` is absent. Lesson: strict deserialization prevents silent misconfiguration that could cause data loss or unexpected retention behavior.

+## Minimum Regression Test Expectations
+
+- Authz fixes: include unauthenticated, valid low-privilege, wrong-action, correct-action, owner, non-owner, and root/admin cases as applicable.
+- Protocol frontend authz fixes: include denied `RETR`, `SIZE`/`MDTM`, `MKD`, bucket probe, and sibling allowed-operation cases; test bucket-policy explicit denies and condition-key denies on each enabled listener against an S3 control, and assert denied paths do not reach storage.
+- IAM fixes: include import/update/list service-account cases with attacker-controlled parent, claims, access key, secret key, and policy.
+- Copy/upload fixes: include cross-bucket, cross-user, source-denied, destination-denied, copy-source-condition, and multipart completion cases.
+- Presigned upload fixes: include a valid presign with extra unsigned tagging, redirect, storage-class, and cross-bucket copy-source headers; require rejection before source or destination storage access, and verify explicitly signed equivalents still work.
+- Version-action fixes: include historical UUID, explicit current version, `null`, range, partNumber, presigned, STS/session, service-account, anonymous bucket-policy, copy source, and multipart-copy source cases.
+- Version-write fixes: a `PutObject`-only principal must not replace an existing version through `PutObject` or browser POST `?versionId=`; verify replication-authorized writes and versioned, suspended, and unversioned buckets separately.
+- Policy-condition fixes: include reserved-key header collisions, missing keys, partially overlapping multi-value sets, plugin mode, and built-in policy mode.
+- Path fixes: include encoded traversal, absolute path, nested traversal, archive entries with `..`, valid object keys that resemble traversal text but should be rejected, and canonical bucket/prefix boundary checks; test per-key `DeleteObjects` errors and prefix-scoped denials on versioned buckets.
+- Logging fixes: assert redacted output for structs and response bodies that may contain credentials.
+- IAM export fixes: assert exported archives omit plaintext user and service-account secrets unless the format deliberately encrypts or seals them.
+- RPC auth fixes: include captured metadata replay across two concrete methods, stale timestamps, wrong path, wrong method surrogate, wrong secret, and valid same-method calls.
+- Browser/CORS fixes: assert no credentials on reflected/default origins, correct behavior for explicit allowlists, and no same-origin script execution for previewed object content.
+- SSE fixes: inspect stored bytes and verify API metadata, read-back behavior, and on-disk ciphertext together; for ETags, upload equal plaintext under different keys and assert list-only callers cannot derive or correlate the plaintext digest, including multipart objects.
+- Object Lock fixes: include unreadable metadata, fabricated metadata defaults, unparsable config, confirmed absent config, COMPLIANCE/GOVERNANCE retention, lifecycle expiry, scanner sweeps, and force-delete paths; an authorized force-delete must preserve active COMPLIANCE versions.

-- Changes to workflow YAML or `.github/actionlint.yaml` must pass `actionlint` (run from the repo root) with zero findings before commit/PR. Install via `brew install actionlint`, or the download script in the actionlint repo (rhysd/actionlint); `make pre-pr` does not cover workflow files, so this is the required check for them.
-- Custom self-hosted runner labels (`sm-standard-*`, `dind-*`) are declared in `.github/actionlint.yaml`. When introducing a new `runs-on:` label, declare it there in the same change. Never use the config or `-ignore` to silence real findings — fix the workflow (root `AGENTS.md`: make checks pass by fixing the cause, not by weakening the gate).
-- If `shellcheck` is installed, actionlint also lints `run:` scripts; treat those findings as part of the gate.
-- Runner placement and billing rules live in `.github/workflows/README.md`. A new job defaults to `ubuntu-latest` (free for this public repository); a self-hosted `runs-on` needs one of the reasons listed there, stated in a comment next to it, and a `rust-cache` key is never shared between the hosted and self-hosted images.

 ## CI Alignment
 
-When changing CI-sensitive behavior, keep local validation aligned with `.github/workflows/ci.yml`. Read the workflow file directly for the current gate steps — do not rely on (or add) a copied command list here; copies go stale. `make pre-pr` covers the shared local gates, not the full CI feature, platform, or end-to-end matrix. Select checks using the root verification tiers.

-# Workflow runners: what is billed and where a job belongs
-
-**Use this when:** adding a job, changing a `runs-on`, moving a lane between runner pools, or deciding whether a new check is worth its runner cost.
-**Source of truth:** `runs-on` in each workflow file for current placement; `.github/actionlint.yaml` for the declared self-hosted labels; the organisation's Settings → Billing → Usage page for what is actually charged; `docs/testing/ci-gates.md` for which checks block a merge (that does not change when a runner changes).
-
-## Billing facts
-
-This repository is public. For a public repository, GitHub's standard hosted runners (`ubuntu-latest`, `windows-latest`, `macos-latest`) cost nothing and have no minute cap, whatever plan the organisation is on. GitHub bills only two things: larger hosted runners, which have custom labels and are not used here, and standard runners in private repositories.
-
-Every other label in this repository is capacity RustFS pays for. ARC pods and lab machines accrue cost while the machine exists. A Ubicloud label is metered for the minutes a job holds its VM:
-
-| Label | Paid by | What it is | Use it for |
-|---|---|---|---|
-| `ubuntu-latest` | nobody | GitHub-hosted, Ubuntu 24.04, 4 vCPU, 16 GB RAM, about 14 GB of free disk. Ships a C toolchain, `docker`, `gh`, `curl`, `wget`, `jq`, Python. Can `mount` tmpfs and loop devices; io_uring works | the default for every job |
-| `windows-latest`, `macos-latest` | nobody | GitHub-hosted standard runners | Windows and macOS targets |
-| `sm-standard-2` | RustFS | ARC pod, Ubuntu 24.04, minimal image: no `gh`, no C toolchain; Docker only on the `dind-` label | only a job that a hosted runner cannot run (see the placement rule) |
-| `sm-standard-4` | RustFS | ARC pod, Ubuntu 24.04, 14 CPUs and 28 GB (the label is not the core count), large disk | workspace-scale Cargo builds |
-| `ubicloud-standard-16-arm` | RustFS | Ubicloud VM, alias of `ubicloud-standard-16-arm-ubuntu-2404`: Ubuntu 24.04 arm64, 16 vCPU, 48 GB, 300 GB disk. Reached through the `build.yml` matrix, so `actionlint.yaml` does not list it | native aarch64 release builds (`linux-aarch64-musl`, `linux-aarch64-gnu`) |
-| `dind-sm-standard-2` | RustFS | ARC pod with Docker-in-Docker | Docker workloads with a measured resource or environment requirement beyond the hosted runner |
-| `smoke-testing`, `pf-testing` | RustFS | long-lived lab machines | the packaged functional chain and performance suites |
-
-The self-hosted pods and the hosted image are both Ubuntu 24.04, so a binary built on one runs on the other; `ci.yml` builds the debug binary on `sm-standard-4` and runs it on both pools.
-
-## Placement rule
-
-A job runs on `ubuntu-latest` unless it has one of these reasons, and the reason goes in a comment next to its `runs-on`:
-
-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.
-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 uses `ubuntu-latest` so a lab outage cannot also stop its independent monitor. 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.
-
-## Cache rule
-
-`Swatinem/rust-cache` builds its key from the OS, architecture, toolchain and lockfile. It does not include the runner label or image, so a cache written on an `sm-standard-4` pod and one written on `ubuntu-latest` would overwrite each other under the same `shared-key`.
-
-- Every `shared-key` has exactly one writer. `cache-warm.yml` owns `ci-dev`, `ci-feat-rio`, `ci-feat-proto` and `ci-uring`; every other `./.github/actions/setup` call states `cache-save-if` explicitly, and `scripts/security/check_cache_save_if.sh` fails the build when one does not.
-- All readers of a key run on the same image as its writer. Keys that live on hosted runners say so in their name (`ci-uring` is warmed on `ubuntu-latest`; `ci-e2e-distributed-hosted`, `e2e-upgrade-server-hosted`, `e2e-upgrade-tests-hosted`).
-- Moving a job between pools therefore means renaming its key. The new key is empty until a run from `main` (a scheduled run, or a manual dispatch of that workflow from `main`) saves it; until then that lane does a cold build. The `build.yml` aarch64 release legs append `-ubicloud-arm` for this reason. `cache-warm.yml` does not write those keys.
-- `CARGO_BUILD_JOBS` and every other `CARGO*`, `CC*`, `CFLAGS*`, `CXX*`, `CMAKE*` and `RUST*` variable is hashed into the key. `ci.yml` sets `CARGO_BUILD_JOBS` at step level for that reason; promoting it to job level rotates the key for every lane that shares it.
-
-## Where self-hosted minutes leak
-
-These are the patterns that have cost real money here without validating anything more:
-
-- An `if: always()` summary or alert job on a self-hosted label inside a `workflow_run`-triggered workflow. The upstream workflow completes many times a day, the real jobs skip, and the summary still starts a pod each time. Gate it on the upstream job having run, and keep it on `ubuntu-latest`.
-- Per-push workflows on `main`. A merge triggers the full `ci.yml` matrix, `cache-warm.yml` and the `build.yml` development build; with tens of merges a day that is as much self-hosted time as all pull requests together. Anything that does not verify the merged tree itself belongs on a schedule or behind a `paths` filter.
-- `apt-get install` of tools the hosted image already ships. It is only needed on the minimal pod images.
-- A throttled `CARGO_BUILD_JOBS` on a 14-CPU pod. The limit exists for link-storm reasons documented in `ci.yml`; measure before raising it, and measure before lowering it further.
-- Tiny jobs on ARC pods. Each one pays roughly a minute of pod start-up before its first step; a compile-free job that takes ten seconds costs more to schedule than to run.
-
-## Measuring a run
-
-To see which pool each job of a run used and for how long:
-
-```bash
-gh api "repos/rustfs/rustfs/actions/runs/<run_id>/jobs?per_page=100" \
-  --jq '.jobs[] | "\(.conclusion)\t\(.labels | join(","))\t\(.started_at)\t\(.completed_at)\t\(.name)"'
-```
-
-Only rows whose label starts with `sm-`, `dind-`, `ubicloud-`, `smoke-` or `pf-` cost anything. At the October 2026 review, a full pull-request run of `ci.yml` spent about 150 self-hosted minutes, a third of it in jobs that never compiled; treat that as the scale of what a placement mistake costs, not as a current figure.
-
-## Checklist for a new or moved job
-
-- `runs-on` is a literal label. A new self-hosted label is declared in `.github/actionlint.yaml` in the same change (`.github/AGENTS.md`).
-- The job declares `timeout-minutes` (`scripts/security/check_job_timeouts.sh`).
-- `actionlint` reports nothing.
-- A self-hosted `runs-on` carries a comment naming its reason from the placement rule.
-- Every `./.github/actions/setup` call states `cache-save-if`, and a key read from one pool is not written from the other.
-- Moving a job does not change its check name, so the `main` ruleset and `docs/testing/ci-gates.md` stay as they are; renaming it does, and then that document's change checklist applies.

+# Warp A/B budget gate for the hotpath series (rustfs/backlog#935 HP-14, item 4).
+#
+# Two entry points, honestly scoped:
+#   * schedule (nightly, on main): post-merge detection — catches a regression
+#     within 24h of landing, not before merge.
+#   * workflow_dispatch: an explicitly selected trusted ref.
+# The dispatch input can run the gate with --allow-regression so a deliberate
+# correctness cost (e.g. the #4221 fsync durability fix) is recorded, not
+# blocked (rustfs/backlog#935 correction 1).
