fix(test): make 4 tests resilient to shared global state in full suite

The scanner_activity, background_heal_status, and two capacity dirty
scope tests assumed no global AppContext or object store was registered.
When run as part of the full test binary, shared_gating_ecstore()
initialises global state (ECStore + notification system) that other tests
pick up via runtime_sources::current_app_context().

- scanner_activity: accept either Unavailable (no storage) or a valid
  response (storage available from shared env)
- background_heal_status: accept either success=false (no storage) or
  success=true with non-empty state
- capacity dirty scope: use filter_map on canonicalize to skip dirty
  disks whose paths are not resolvable on the local filesystem

 # RustFS Release Publish (preview-validated pipeline)
 
 This skill orchestrates a full release. It wraps `rustfs-release-version-bump` (which only edits version files and opens the PR) with a mandatory preview-tag validation loop before the final tag is published.
 
-Core design: **version files never carry a `-preview.N` suffix**. The preview suffix exists only in tag names. A preview tag creates a visible GitHub Release marked Prerelease and uploads versioned assets, but it never becomes GitHub Latest and never updates `*-latest`, `latest.json`, R2, Docker, or Helm channels. This works because the binary self-reports the git tag it was built from (`build::TAG` via shadow_rs, see `rustfs/src/config/cli.rs` `SHORT_VERSION`), and `build.yml` derives artifact names and preview classification from the tag name — Cargo.toml's version is only a no-tag fallback. Therefore the preview tag and the final tag can (and MUST) point at the exact same commit: what you validated is byte-for-byte the source that ships.

 ## Preview tag naming
 
-- Use `<target>-preview.N` for every target, e.g. `1.0.0-beta.10-preview.3` or `1.1.0-preview.1`.
-- The canonical suffix is exactly `-preview.<digits>`. `build.yml` recognizes it before alpha/beta/rc classification and routes it to the preview-only path; any other tag containing `-preview` fails closed instead of being treated as a release.
-- A preview Release MUST be published with `isPrerelease=true` and `isLatest=false`. Any `*-latest` preview asset or preview-triggered `latest.json`, R2, Docker, or Helm publication is a pipeline failure.
+- Prerelease target (contains `alpha`/`beta`/`rc`): preview tag is `<target>-preview.N`, e.g. `1.0.0-beta.10-preview.3`. It contains `beta`, so `build.yml`'s substring-based classification marks it prerelease — safe.
+- **Stable** target (e.g. `1.1.0`): NEVER tag `1.1.0-preview.N` — `build.yml` marks a tag prerelease only if its name contains `alpha`, `beta`, or `rc`, so `1.1.0-preview.N` would be treated as a stable release and overwrite `latest.json` as stable. Use `1.1.0-rc.N` as the preview tag instead.
 
 ## Hard rules
 
 - Version files (Cargo.toml, Cargo.lock, README, flake.nix, Chart.yaml, rustfs.spec) are bumped ONCE, directly to `<target>`. Never write a `-preview.N` suffix into any version file. If `rustfs-release-version-bump` is ever asked for a `-preview` version, that is a pipeline bug — stop.
-- Preview Release assets are versioned and intentionally visible on the Releases page. Do not label them Latest or use them to update any latest distribution channel.
 - Tags have no `v` prefix. Always annotated: `git tag -a <tag> -m "Release <tag>"`.
 - The final tag MUST point at exactly `PREVIEW_HASH` — the commit the validated preview tag points at. Never tag current `main` HEAD (commits merged after validation are unvalidated), and never create an extra version-bump commit between preview and final.
-- When a previous deliverable exists, GitHub Release notes for the preview and final tags MUST use it as their shared comparison baseline: the most recently published non-preview Release before the target. Internal `-preview.N` Releases are explicitly excluded from that selection, even when they point at the same commit as the final tag. If no previous deliverable exists, omit `previous_tag_name` and record that GitHub's default baseline fallback was used.
-- Generated Release notes carry a workflow-management marker so retries can repair them. Before manually curating a generated body, remove that marker; unmarked non-placeholder notes are preserved by later workflow runs.
 - Phases run in order; a failure in any phase blocks everything after it. After the fix lands on main, restart from Phase 2 with the next preview iteration against the new `origin/main` hash — do not resume mid-pipeline against a stale hash.
 - If the release is abandoned after Phase 1 merged, main's version files claim a version that was never tagged. Either revert the bump PR or leave it to be overwritten by the next release — but tell the user explicitly and record the decision.

-### Console release gate
-
-Complete this gate before changing any RustFS version file or creating any RustFS tag. RustFS `build.yml` downloads the asset returned by `repos/rustfs/console/releases/latest`, so a successful Console build alone is insufficient.
-
-1. Read the latest published Console tag and compare it with Console `main`:
-
-```bash
-CONSOLE_REPO="rustfs/console"
-CONSOLE_LATEST=$(gh api "repos/${CONSOLE_REPO}/releases/latest" --jq .tag_name)
-gh api "repos/${CONSOLE_REPO}/compare/${CONSOLE_LATEST}...main" \
-  --jq '{status, ahead_by, behind_by, commits: [.commits[] | {sha, message: .commit.message}]}'
-```
-
-- `ahead_by == 0`: no merged Console change is waiting for release. Still verify the current latest asset using step 4, then continue to Phase 1.
-- `ahead_by > 0` and `behind_by == 0`: publish Console before continuing. Report the merged commits and select the next unused `vX.Y.Z` tag. Default to the next patch version when the changes are fixes or backward-compatible UI work; stop for confirmation if a minor/major bump is plausible.
-- Any diverged history or `behind_by > 0`: stop and resolve the Console release baseline explicitly. Do not guess a range or publish RustFS.
-
-2. Clone/fetch `rustfs/console` into a scratch directory and record its exact `main` commit. Before creating a tag, check for a `v*` tag or Release workflow already associated with that hash. If one is in progress, wait for it instead of creating another version:
-
-```bash
-CONSOLE_SCRATCH=$(mktemp -d)
-gh repo clone "$CONSOLE_REPO" "$CONSOLE_SCRATCH/console"
-git -C "$CONSOLE_SCRATCH/console" fetch origin main --tags
-CONSOLE_HASH=$(git -C "$CONSOLE_SCRATCH/console" rev-parse origin/main)
-git -C "$CONSOLE_SCRATCH/console" tag --points-at "$CONSOLE_HASH" 'v*'
-gh run list -R "$CONSOLE_REPO" --workflow release.yml --commit "$CONSOLE_HASH" --limit 5
-```
-
-If no release exists or is running for `CONSOLE_HASH`, create the selected annotated tag at that exact hash and push it:
-
-```bash
-git -C "$CONSOLE_SCRATCH/console" tag -a "<console-tag>" -m "Release <console-tag>" "$CONSOLE_HASH"
-git -C "$CONSOLE_SCRATCH/console" push origin "<console-tag>"
-```
-
-Console tags include the `v` prefix. Pushing the tag triggers `.github/workflows/release.yml` (`🚀 Release`). Remove `CONSOLE_SCRATCH` after the gate completes.
-
-3. Find the exact tag run and wait for completion:
-
-```bash
-gh run list -R "$CONSOLE_REPO" --workflow release.yml --branch "<console-tag>" --limit 1
-gh run watch -R "$CONSOLE_REPO" "<console-run-id>" --exit-status
-```
-
-4. Block until the published Release is non-draft, the latest endpoint returns the expected tag, and `rustfs-console-<console-tag>.zip` is uploaded, non-empty, and carries a `sha256:` digest:
-
-```bash
-gh release view -R "$CONSOLE_REPO" "<console-tag>" --json isDraft,isPrerelease,assets,url
-test "$(gh api "repos/${CONSOLE_REPO}/releases/latest" --jq .tag_name)" = "<console-tag>"
-test "$(gh api "repos/${CONSOLE_REPO}/releases/tags/<console-tag>" \
-  --jq '[.assets[] | select(.name == "rustfs-console-<console-tag>.zip" and .state == "uploaded" and .size > 0 and (.digest | startswith("sha256:")))] | length')" -eq 1
-```
-
-Treat a missing/mismatched asset, digest, latest tag, or failed/cancelled workflow as BLOCKED. Do not start Phase 1 until the Console gate passes. Record `CONSOLE_TAG`, `CONSOLE_HASH`, Console run URL, and Release URL for the final report.
-

-# Sole writer of the Rust dependency caches that ci.yml restores.
-#
-# Why this is a separate workflow rather than steps inside ci.yml: ci.yml's
-# concurrency group cancels in-progress runs on main pushes, and merges land far
-# faster than its 70-minute pipeline. Measured over 15 consecutive main pushes:
-# 12 cancelled, 2 failed, 0 succeeded. A cancelled run never reaches
-# Swatinem/rust-cache's post step (cache-on-failure does not cover cancellation),
-# so the writer lanes were saving nothing and every PR paid a cold restore —
-# 11.8-20.9 minutes of "Setup Rust environment" against 0.7-3.4 warm.
-#
-# Splitting cache writing out of the test pipeline lets ci.yml keep cancelling
-# superseded runs (which is correct — nobody needs test results for a commit
-# that is already three merges behind) while the caches still get written.
-#
-# The group below deliberately does NOT cancel in progress; see the comment on
-# it for how that bounds concurrency and why it is scoped by event.
-#
-# Each job below owns exactly one shared-key and is the only place that sets
-# cache-save-if to anything but 'false' for it; every lane in ci.yml reads.
-# scripts/security/check_cache_save_if.sh keeps the declarations explicit.
-#
-# The builds are supersets of what the reading lanes compile, because a reader
-# restores only what the writer saved. Feature resolution matters here: a lane
-# built with e2e-test-hooks resolves dependency features differently, which
-# changes -Cmetadata, so the plain build does not cover it. See

-## Worktree and Disk Hygiene
-
-- Unless the requester explicitly says otherwise, treat every new implementation task as isolated work: fetch the latest `origin/main`, confirm the requested change is not already present there, and create a dedicated feature branch and worktree from that exact upstream commit before editing. Do not implement new work directly in the primary checkout or reuse a worktree from another task.
-- Check available disk space before creating the worktree or starting dependency downloads, builds, tests, coverage, or other artifact-heavy commands. For long-running or artifact-heavy work, re-check disk usage at natural phase boundaries and before broad validation; if remaining space may not safely accommodate the next command, stop and reclaim task-owned artifacts before continuing.
-- Keep cleanup scoped and safe: remove generated build/test/coverage artifacts and temporary files created by the task when they are no longer needed, and never delete another task's worktree or uncommitted files. Prefer shared dependency caches where supported instead of duplicating large artifacts across worktrees.
-- At handoff, report the disk-space checks, cleanup performed, and any retained worktree or artifacts with the reason they are still needed.
-
-## PR Lifecycle Monitoring
-
-- Creating or updating a PR is not the terminal state. Unless the requester explicitly limits the task to PR creation, monitor the PR through its terminal state: merged, closed, or explicitly handed off because progress requires user or maintainer action.
-- While the task is active, monitor CI/check runs, review decisions and unresolved threads, mergeability and conflicts, and unexpected head/base changes. Prefer event-driven or bounded waits provided by the current environment over frequent polling; report only state changes, actionable failures, or meaningful prolonged delays.
-- Investigate every failing check and review comment before changing code. Fix failures attributable to the task, run the verification required for the new diff, push the update, respond to or resolve the corresponding review threads, and resume monitoring. Do not weaken checks, dismiss valid feedback, or retry flaky failures merely to obtain a green result.
-- Treat opening, green CI, approval, and mergeability as intermediate states. Never merge without the required reviewer approval or explicit authority. If progress depends on credentials, infrastructure, a maintainer decision, or another external action, report the exact blocker and the evidence already collected.
-- If the current execution environment cannot remain active until the next PR event, use a supported automation, monitor, or thread wakeup when available and within scope. Otherwise leave an explicit handoff containing the PR, current state, next event to observe, and pending cleanup; do not imply that background monitoring exists when none is scheduled.
-- After observing a merge, verify the commits are preserved on the upstream base, ensure the worktree is clean, remove the dedicated worktree, prune stale worktree metadata, and delete the local task branch when it is no longer in use. For a closed or abandoned PR, preserve any unmerged work unless deletion was explicitly authorized. Do not delete remote branches unless explicitly requested or repository automation owns that cleanup.
-
-## Autonomy and Approval Boundaries
-
-- Inquiry tasks (answer, explain, review, diagnose, plan): report findings; do not change files unless a fix is explicitly requested.
-- Action tasks (change, build, fix): make in-scope local changes without asking for approval.
-- Ask for confirmation before destructive or hard-to-reverse operations (force-pushes, history rewrites, deleting data or branches), merging a PR (reviewer approval required), or any material expansion of the requested scope.

-Convert changes into independently verifiable outcomes. This section controls

-the broadest gate. Inspect only the final task-owned diff, classify it by
-behavioral impact rather than line count or path alone, and run the smallest
-set of checks that provides meaningful coverage. Do not let unrelated
-worktree changes or a generic contributor checklist expand the scope.
-Non-exempt changes must also pass Adversarial Validation (next section) before

+Convert changes into independently verifiable outcomes. Prefer focused tests for behavior changes and run the relevant checks before declaring completion.
+Non-exempt changes must also pass Adversarial Validation (next section) before the checks below count as completion.
 
-### Validation floor
+For code changes, run and pass the following before opening a PR:
 
-- Every change that is not documentation-only must finish with
-  `cargo fmt --all --check` passing. An umbrella gate that runs this exact
-  check satisfies the requirement; do not run it twice. Use `cargo fmt --all`
-  only when formatting needs to be fixed. Run the configured formatter or
-  validator for other changed languages when one exists.
-- Documentation-only or instruction-only means all task-owned changes are
-  prose or documentation assets and cannot affect runtime, builds, CI,
-  dependencies, generated code, or tests. Run `git diff --check` and any
-  relevant documentation guard, but skip Cargo formatting, compilation,
-  Clippy, tests, `make pre-commit`, and `make pre-pr`.
-- Behavior changes require relevant existing or new tests. Prefer the most
-  focused test or affected package. A passing targeted test can also provide
-  sufficient compilation coverage when it builds every changed target and
-  feature involved; do not add a redundant `cargo check` in that case.
-- `cargo check` supplements compilation coverage; it never substitutes for a
-  behavioral test. If a relevant test cannot reasonably be added or run, use
-  the narrowest compilation check and report the reason and remaining risk.
+```bash
+make pre-pr
+```
 
-### Validation tiers
+Before committing code changes, prefer focused verification for the touched
+surface and use the faster local gate when a broad smoke check is needed:
 
-1. **Documentation/instruction-only:** Apply the exemption above. Run a guard
-   such as `make doc-paths-check` only when it is relevant to the edited text.
-2. **Non-behavioral source change:** For comments, formatting, or another
-   demonstrably non-executable change, run the formatting floor. Compilation,
-   Clippy, and tests may be skipped only when the edit cannot affect
-   compilation or runtime behavior; run targeted doctests if executable
-   documentation examples changed.
-3. **Localized or bounded behavior change:** Run the formatting floor and the
-   narrowest relevant tests. Add package-scoped `cargo check` or Clippy only
-   for changed targets, features, APIs, error handling, async behavior, or
-   control flow not already covered. When several crates are affected but the
-   dependency set is identifiable, validate those packages and known
-   dependents instead of the whole workspace. Use `make pre-commit` only when
-   a repository-wide fast gate adds useful confidence beyond those checks.
-4. **Broad or high-risk change:** Run `make pre-pr` only when targeted coverage
-   cannot bound the impact, including:
-   - dependency, feature, build-script, procedural-macro, code-generation,
-     toolchain, or CI changes that alter compilation or the test matrix;
-   - cross-crate public APIs, shared foundational code, or broad refactors with
-     an unbounded dependent set;
-   - locking, storage durability or formats, erasure coding, replication,
-     RPC/protocol compatibility, IAM/KMS/auth, cryptography, or other
-     security-sensitive behavior;
-   - a targeted check that reveals wider impact, an explicit user request, or
-     a release policy that requires the full gate.
+```bash
+make pre-commit
+```
 
-Documentation-only and non-behavioral classifications take precedence over
-path-based triggers. A small diff can still be high-risk, while a CI comment,
-manifest comment, or release-note edit does not require full validation.
+For migration batches, do not run the full `make pre-pr` gate before every
+intermediate commit. Use focused tests and `make pre-commit` during
+development, then reserve `make pre-pr` for the final PR-ready branch.
 
-`make pre-pr` includes `make pre-commit` coverage. Never run both for the same
-unchanged diff, and do not repeat equivalent checks during PR preparation or
-because a local hook already ran them. Rerun only checks whose scope is affected
-by later edits. Full workspace checks do not replace a relevant integration or
-E2E test for changed behavior; run that focused test when required and
-available, or report why it was not run and the remaining risk.
+Before pushing code changes, make sure formatting is clean:
 
-If `make` is unavailable, run the equivalent checks defined under
-`.config/make/`. At handoff, list the checks actually run, checks intentionally
-skipped, and the reason for the selected tier.
+- Run `cargo fmt --all`.
+- Run `cargo fmt --all --check` and ensure no files are modified unexpectedly.
 
+If `make` is unavailable, run the equivalent checks defined under `.config/make/`.
+Documentation-only or instruction-only changes are exempt from the verification commands above (including the `.config/make/` equivalents), though any locally installed git pre-commit hooks may still run on commit unless explicitly skipped.
 After build-based verification completes, clean generated build artifacts before wrapping up to avoid unnecessary disk usage.
 Do not open a PR with code changes when the required checks fail.

 - `RUSTFS_NOTIFY_WEBHOOK_SKIP_TLS_VERIFY_PRIMARY` defaults to `false`; enabling it skips webhook TLS certificate verification, allows MITM attacks, and emits a startup warning. Prefer `RUSTFS_NOTIFY_WEBHOOK_CLIENT_CA_PRIMARY` for private CAs.

 - `RUSTFS_BROWSER_REDIRECT_URL` sets the externally reachable browser origin used for OIDC callback, console success redirect, and logout fallback URLs. Configure it to the public scheme and authority without a path, for example `https://console.example.com`. In load-balancer deployments, keep OIDC authorize and callback requests on the same backend node because the in-flight OIDC `state` is local to the RustFS node.
 
-## Distributed endpoint locality
-
-- `RUSTFS_LOCAL_ENDPOINT_HOST` identifies this server's host in a distributed `RUSTFS_VOLUMES` topology without resolving every peer during startup. Set it to exactly one host, without a scheme, port, or path. It is accepted only for orchestrated URL topologies and must match at least one endpoint on the RustFS server port; invalid or unmatched values fail startup. Leave it unset to retain DNS-based locality discovery.

-//! Cross-process replay / tamper acceptance for internode NodeService RPC
-//! signatures (<https://github.com/rustfs/backlog/issues/1327>,
-//! <https://github.com/rustfs/backlog/issues/1542>).
-//!
-//! # Why this exists on top of the in-process tests
-//!
-//! `http_auth.rs` unit-tests the signature algebra by calling the verifier
-//! directly. That proves the crypto, but it cannot prove that a *deployed*
-//! server actually reaches it: the request has to survive the hybrid HTTP/gRPC
-//! router, `check_auth`, tonic's own metadata handling, and finally the
-//! per-handler body-digest gate. A handler that forgets its
-//! `verify_disk_mutation_digest` call, or a router change that bypasses
-//! `check_auth`, is invisible in-process and wide open in production. These
-//! tests drive a real `rustfs` child process over a real TCP socket, so every
-//! one of those layers is in the path.
-//!
-//! # Attacker model
-//!
-//! The adversary is on-path: it observed one legitimately signed request and
-//! can resend, retarget, or edit those bytes — including individual headers.
-//! It does **not** hold the RPC secret. The test process does hold the secret,
-//! but uses it for exactly one purpose: minting the request that stands in for
-//! the captured one. Every attack then only *reuses or edits* an already-minted
-//! header set; no attack step ever re-signs. If any of these tests could pass
-//! by re-signing, it would be testing nothing.
-//!
-//! # Isolating one variable at a time
-//!
-//! Each rejection is paired with an acceptance that differs in exactly one
-//! respect, because a misconfigured harness (wrong audience, dead server,
-//! ambient strict env) would otherwise make every "rejected" assertion pass
-//! vacuously. Two pairings carry most of the weight:
-//!
-//! - Editing the body alone is caught by the *handler* (`PermissionDenied`);
-//!   editing the body **and** repairing the digest header to match is caught by
-//!   the *signature* (`Unauthenticated`). The second only fails closed if the
-//!   digest is genuinely inside the signed scope, so the pair pins both layers.
-//! - Replaying a captured nonce is caught by the replay cache; swapping in a
-//!   fresh nonce is caught by the signature. Again, only the pair proves the
-//!   nonce is signed rather than merely cached.
-//!
-//! # Why `MakeVolume` against a non-existent disk
-//!
-//! Every covered handler checks the digest before touching storage, and
-//! `MakeVolume` resolves its disk *after* that check. Aiming at a disk that
-//! cannot exist gives three cleanly separable outcomes with zero side effects
-//! on the server's real data:
-//!
-//! - `Err(Unauthenticated)` — rejected by `check_auth` (signature layer).
-//! - `Err(PermissionDenied)` — rejected by the handler's body-digest gate.
-//! - `Ok(success: false)` — **authentication passed**; the request reached
-//!   handler logic and only then failed on the bogus disk.
-//!
-//! # Coverage of the issue's acceptance matrix
-//!
-//! | Acceptance item | Test |
-//! |---|---|
-//! | replay a signature onto another method → reject | [`cross_method_signature_transplant_is_rejected`] |
-//! | replay same method + body after nonce consumed → reject | [`nonce_replay_of_a_captured_mutation_is_rejected`] |
-//! | nonce is signed, not just cached → reject a swapped nonce | [`swapping_in_a_fresh_nonce_is_rejected`] |
-//! | tamper one byte of the body → reject | [`tampered_mutation_body_is_rejected`] |
-//! | body digest is inside the signed scope → reject a repaired digest | [`rewriting_the_digest_to_match_a_tampered_body_is_rejected`] |
-//! | wrong destination node identity → reject | [`signature_minted_for_another_node_is_rejected`] |
-//! | mixed version: legacy-only still served, not blocked | [`legacy_only_signature_is_accepted_in_default_posture`] |
-//! | strict flip closes the signature downgrade | [`signature_strict_rejects_legacy_only_downgrade`] |
-//! | strict flip closes the body-digest downgrade, incl. v1 | [`body_digest_strict_rejects_digestless_mutation`] |
-//! | replay scope binds every RPC and rejects restart replay | [`replay_scope_rejects_replay_path_transplant_and_stale_epoch_e2e`] |
-//! | strict replay scope allows only Ping bootstrap before v3 | [`replay_scope_strict_requires_v3_after_ping_bootstrap_e2e`] |
-//!
-//! Two acceptance items are deliberately left to the in-process tests. A stale
-//! timestamp cannot be forged from outside — it is inside the HMAC — so
-//! observing it would mean idling out the full freshness window. And the
-//! `signature_v1_fallback_total` / `body_digest_fallback_total` counter deltas
-//! that gate the strict flips are asserted directly in `http_auth.rs`; the
-//! legacy test below proves only the *accepted* half of that behaviour.

-//! Regression test: a same-key CopyObject that only rewrites metadata must never re-key a
-//! managed-SSE (SSE-S3 / SSE-KMS) object.
-//!
-//! On an **unversioned** bucket the handler marks a same-name copy `metadata_only`, and the
-//! store layer then updates `xl.meta` in place without touching the data blocks. The handler
-//! nevertheless strips the source encryption metadata and generates a *fresh* DEK for the
-//! destination. Combining the two writes "new DEK + old ciphertext": the object is permanently
-//! undecryptable. The fix forces a full data rewrite whenever the copy re-derives managed
-//! encryption material, so the stored bytes always match the key metadata beside them.
-//!
-//! Companion to `copy_object_version_restore_sse_test` (issue #4238), which pins the same
-//! invariant for the versioned historical-restore path.

-//! Negative authorization matrix for per-key KMS access control.
-//!
-//! Every case here is an end-to-end denial that the pre-`kms` resource server
-//! allowed, so a regression that reopens one of them fails this file rather than
-//! only a unit test. The matrix varies one dimension at a time:
-//!
-//! - **wrong identity**: a caller holding S3 rights but no `kms` grant at all
-//! - **wrong key**: a caller scoped to key A naming key B
-//! - **wrong action**: a caller holding `kms:GenerateDataKey` but not `kms:Decrypt`
-//!   (and, on the admin plane, `kms:DisableKey` but not `kms:RotateKey`)
-//! - **wrong context**: an explicit `Deny` beating a wildcard `Allow`, and SSE-S3
-//!   staying exempt from `kms` authorization
-//!
-//! Each matrix opens with a positive control. Without it a denial proves nothing:
-//! an identity whose policy has not propagated yet is denied everything.
