fix(ecstore): clear stale BucketMetadataSys on ECStore drop (#9097)

When sequential test fixtures share the bootstrap InstanceContext, the
BucketMetadataSys stores a Weak<ECStore> to avoid a reference cycle. The
ExpiryState holds an Arc<ECStore> that keeps the store alive past the
test's own Arc drop; the next fixture's resize_workers releases it and
the weak goes dangling before init_bucket_metadata_sys installs a fresh
BucketMetadataSys. Any object_store() call in that window panicked.

Add Drop for ECStore that clears the context's BucketMetadataSys slot
when its weak handle is stale, so the next fixture always finds a clean
slot. Fixes the heal absence_receipt_regressions and dangling_grace
test failures under sequential execution.

 PRs changing only Rust sources under `crates/e2e_test/src/` and known E2E selection digests (optionally with those documentation paths) use the `e2e` scope. They keep workspace validation, the server build, E2E smoke, and both S3 lanes; independent workflows retain their path selection. Connect boundary, serial ILM, optional protocol/rio-v2, and real io_uring jobs are skipped because their sources and test inputs are unchanged. Manifests, fixtures, shared nextest configuration, scripts, production sources, and unknown paths still select `full`. A dependency on `e2e_test` from another workspace member or reachable local dependency disables this shortcut. All non-PR events retain their full selection. The structured planner enforces affected-package and Connect selection from the trusted base policy, retaining fixed core coverage and full validation for shared or unknown inputs. See [verification plans and artifacts](ci-verification-pipeline.md) for identity, rollout and queue-switch contracts.
 
-Alternate-feature unit tests and Clippy for rio-v2, Swift, SFTP, and HTTP/3 run on merge groups and on scheduled (nightly) or manual validation. PRs and main pushes run the default workspace and retain ILM, S3, real io_uring, and Connect security boundaries in their applicable scopes. The aggregate requires the alternate-feature jobs to be skipped on PRs and main pushes and successful on merge-group, scheduled, and manual events. This avoids repeating four feature builds on every PR revision and on every merge; feature-specific regressions are detected by the nightly run when the merge queue is not used. For changes to these features, dispatch `ci.yml` against the candidate branch before merging when that signal is needed, including PRs targeting `gateway/integration`, which has no automatic push trigger in this workflow. Scheduled results supplement the main baseline and do not replace it.
+Specialized boundary, hardware and alternate-feature lanes run only on the scheduled (nightly) and manual full-validation runs: `Connect Feature Boundaries`, `io_uring Integration (real)`, and the rio-v2, Swift, SFTP and HTTP/3 feature lanes. They do not gate a merge. The nightly run reports their regressions within a day, and repeating these builds on every PR revision and merge group bought no earlier signal worth the runner occupancy (Connect alone measured 53.5 median minutes per run and occasionally set the wall). PRs, merge groups and main pushes run the default workspace and retain ILM, S3, E2E smoke, the short core contract and the debug build. The aggregate requires the specialized lanes to be skipped on pull-request, merge-group and push events and successful on scheduled and manual events. For changes to these features, dispatch `ci.yml` against the candidate branch before merging when that signal is needed, including PRs targeting `gateway/integration`, which has no automatic push trigger in this workflow. Scheduled results supplement the main baseline and do not replace it.
 
 Workspace Clippy runs on every event with a selected workspace Rust job, pull requests included, in `Workspace Lint and Build`. That job also creates the exact test archive and runs doctests; `Workspace tests` consumes the archive without rebuilding it. `cache-warm.yml` warms Clippy's check artifacts under `ci-dev` with the same invocation to reuse compatible dependency artifacts. `make pre-commit` does not run Clippy. Select local Clippy targets, features, and documentation exemptions from the root `AGENTS.md` verification tier; the workspace command below reproduces the CI lane and is not a universal pre-push requirement.

 ## Release validation
 
-Post-merge and tag-driven; not a substitute for a PR gate.
+Post-merge and tag-driven; not a substitute for a PR gate. Every public publication exit consumes the release certification described here; this certification path is separate from the reusable CI artifact contract in [verification plans](ci-verification-pipeline.md), whose archives expire after one day and are never used as release certification.
+
+The versioned plan is `.config/release-validation-plan.json` (`schema_version=1`): release types, target OS/arch/ABI, supported features, a fixed harness SHA per lane, required case IDs, environment capabilities, timeouts, applicability conditions, and an explicit `upgrade_sources` list carrying the real artifact digests of the supported N-1/N-2 sources plus a stated rollback basis — compatibility and rollback are never invented or defaulted. `scripts/release/release_gate.py validate` expands and freezes `plan_sha256` and the required case set before reading results, then binds that plan, a `candidate.json` (product 40-character SHA, version, release profile, features, immutable deliverable locations with SHA256 and wrapped-binary SHA256, image digest) and the shared G01 evidence-envelope set (rustfs/backlog#2658) of one parent candidate batch, and writes machine JSON, JUnit and a summary. Within a batch the unique key is `(lane, platform{os,arch,abi}, case_id)`; the top-level run/attempt is the parent batch and the nested workflow run/attempt is the child workflow identity, and both are validated separately (workflow SHA and product build SHA are bound independently and need not be equal). Missing, duplicate or extra cases, stale attempts, wrong digests, wrong platforms, wrong harness SHAs, zero tests, cancellation, timeout, untrusted sources and any non-PASS required item block with classified errors; only a complete legal success returns 0. `verify-promotion` re-checks the exact bytes about to be published against the passed list and fails on a swapped package or an edited plan after verification. preview, prerelease and stable all require an explicit plan; preview may use the plan's smaller pre-declared set but never bypasses artifact identity and startup checks. development artifacts are explicitly uncertified and never touch official or latest channels.

+| Exit | Writer | Certification consumed |
+|---|---|---|
+| GitHub Release draft → public | `build.yml` `publish-release` | `release-certification` success and per-asset `verify-promotion` |
+| Official R2 binary path `artifacts/rustfs/release/` | `build.yml` `promote-release-artifacts` | `release-certification` plus `verify-promotion`; the build job itself only writes `artifacts/rustfs/staging/<run>/<attempt>/` |
+| `latest.json` version pointer | `build.yml` `update-latest-version` | transitively through `publish-release` |
+| Image channels (Docker Hub, GHCR, Quay tags) | `docker.yml` `build-docker` promotion step | certified input digests, staged image binary identity and `verify-promotion`, then promotion of the same digest with `imagetools create` |
+| Official R2 package paths `packages/release` and `packages/latest` | `package.yml` `promote-packages` | `release-certification` and wrapped-binary `verify-promotion`; the package job only stages |
+| GitHub release package assets | `package.yml` `package` | `release-certification` and wrapped-binary `verify-promotion` before upload |
+| Helm chart repository (`rustfs/helm` push) | `helm-package.yml` `publish-helm-package` | `release-certification` plus the Docker workflow's image-promotion record bound to the same candidate |
+
+Downstream workflows fail closed when the trusted certification is absent: a manual dispatch without certification fails and pushes no official tag. Only results from the trusted verification sources listed in the plan (currently the `rustfs/s3chaos` `release-gate.yml` envelope runs) carry release authority; a PR-uploaded JSON set cannot certify a release. Retries reuse the same candidate, only the staged bytes are promoted (no rebuild-after-verify), and no downstream step re-resolves a mutable `latest`.
+
+Use an exact preview tag for an end-to-end release rehearsal. Manual dispatches are backfill/debug paths and do not prove the automatic `workflow_run` chain. The committed fixtures under `testdata/release-gate/` and the commands below are contract rehearsals of this orchestration; they are explicitly not product release evidence and not live verifier results.

-The existing `ci.yml` test-and-lint job runs the ordinary ECStore and filemeta tests. After that run, `scripts/check_test_wiring.py --check-core` checks the same nextest profile and package selection against `.config/ecstore-required-tests.json`. Every named test must exist, match the filter, and be non-ignored; the job also requires a nonempty JUnit report.

 The manifest records a minimum set of invariants: write quorum, metadata rollback, stale-writer lock loss, plaintext Range content, multipart cancellation, hiding uncommitted LIST versions, real MinIO metadata, corrupt part arrays, and the shared on-demand-migration source-backend contract for each provider dialect (S3, Azure, native GCS). The three contract entries live in the `rustfs` suite and reach the lane through that package's default features, so dropping `gcs` from `rustfs`'s defaults fails this check instead of silently deselecting the GCS contract (rustfs/backlog#2323). Renaming or moving a required test must update the manifest in the same change after checking the compiled listing. Extend this list as new deterministic regressions land; it is not a claim that all storage invariants are covered.

+# CI timing sample 2026-10-31 (backlog #2963 CI01 measurement)
+
+Operational measurement of ordinary-code PR feedback and runner occupancy against the CI01 experimental targets (feedback median 15–20 min, P95 ≤ 30 min, paid occupancy median 50–60 runner minutes). Methodology: [ci-timing.md](ci-timing.md) and [ci-resource-accounting.md](ci-resource-accounting.md). Raw snapshots: `/tmp/ci-timing.json` (limit 30 reproduction), `/tmp/ci-timing-200.json` (analysis sample), `/tmp/ci-acc-w{1,3}.json`. Nothing in this report is an acceptance result; the targets are **not met** by the measured sample.
+
+## Sample window and n
+
+| Item | Value |
+|---|---|
+| Collection time | 2026-10-31 ~02:50–03:15 UTC |
+| Window | completed `pull_request` runs of `ci.yml` created in the last 7 days |
+| Runs sampled | 30 (reproduction) and 200 (analysis, script max) |
+| Successful-code runs (classifier) | 1 of 30; **39 of 200** |
+| Other outcomes in 200-run sample | 68 cancelled (34 %), 36 failed, remainder non-code greens/closure handlers |
+| Lane shapes in sample | 24 combined-lane runs (`Workspace Test and Lint`), 15 split-lane runs (`Workspace Lint and Build` + `Workspace tests` + `Core contract`) |
+
+The limit-30 reproduction reports median wall 76.85 min and median job-sum 133.33 runner-min on n=1 (per methodology, an absent/small median is not zero). All medians/P95 below are from the n=39 analysis sample. Two of the 39 are rerun continuations (run_attempt > 1, wall 7.0 and 22.6 min re-executing only failed jobs under the rerun-start convention); they do not move the median.
+
+## Measured feedback and occupancy (ordinary successful code runs, n=39)
+
+| Metric | Median | P90 | P95 | Max |
+|---|---|---|---|---|
+| Wall feedback (created/rerun-start → last job end) | **76.3 min** | 94.5 | **97.0** | 103.2 |
+| Runner-minute job sum per run | **179.5** | 206.5 | **213.6** | 220.4 |
+
+Independent accounting cross-check (`scripts/ci/actions_cost_report.py`, 2026-10-30T00–12Z window, 547 attempts, collection **incomplete** — see gaps): successful-code PR feedback median 88.34 min (n=12), runner_sum median 199.68 min (n=12). A complete half-day window (2026-10-31T00–12Z, 78 attempts) shows total known runner occupancy 1379.72 min with 42 jobs of unknown occupancy; queue wait summed 28.43 min, so queueing is not the dominant cost.
+
+## Per-job critical path breakdown
+
+Execution minutes across the 39 runs (known only):
+
+| Job | n | Median | P95 |
+|---|---|---|---|
+| Workspace Test and Lint (combined lane) | 24 | 63.6 | 73.9 |
+| Connect Feature Boundaries | 38 | 53.5 | 70.4 |
+| Workspace Lint and Build (split lane) | 15 | 43.3 | 56.5 |
+| Workspace tests (split lane) | 15 | 29.2 | 43.0 |
+| Build RustFS Debug Binary | 39 | 18.5 | 24.9 |
+| End-to-End Tests | 39 | 11.4 | 16.7 |
+| S3 Implemented Tests | 39 | 9.8 | 11.1 |
+| io_uring Integration (real) | 39 | 7.7 | 8.8 |
+| Quick Checks | 39 | 7.2 | 9.2 |
+
+Per-run chain timeline (start = attempt start; see `/tmp/per-run-jobs.json`):
+
+- Split lane (15 runs): `Quick Checks` (~7–10) → `Workspace Lint and Build` (ends ~46–67) → `Workspace tests` (ends ~71–103) → shard evidence → aggregator `Test and Lint`/`required-checks`. The lint→tests chain sets the wall in most split runs.
+- Combined lane (24 runs): `Quick Checks` → `Workspace Test and Lint` alone runs 63–86 min and sets the wall.
+- `Connect Feature Boundaries` (median 53.5, P95 70.4) runs parallel to the lint chain and occasionally becomes the tail (e.g. runs 41021787700, 40750122159: connect end within 0.2 min of wall).
+- `Build RustFS Debug Binary` → E2E/Core-contract/S3 chain finishes with 30–60 min of slack in every sampled run.
+- The required-check aggregator `Test and Lint` (`required-checks`, `ci_gate.py verify`) finishes last by construction (~0.2 min).
+
+## Against the CI01 targets
+
+| Target | Measured | Verdict |
+|---|---|---|
+| Feedback median 15–20 min | 76.3 min (n=39) | **not met** (~3.8–5× over) |
+| Feedback P95 ≤ 30 min | 97.0 min | **not met** (~3.2× over) |
+| Occupancy median 50–60 runner-min | 179.5 runner-min | **not met** (~3–3.6× over) |
+
+These are the experimental-target measurements. The full merge-lifecycle cost is separate and was not established here (the accounting PR-allocation buckets were empty in the partial window; see gaps).
+
+## Bottlenecks (honest list)
+
+1. **Workspace lint+test compile/test chain (critical path):** combined `Workspace Test and Lint` median 63.6 min, or split `Workspace Lint and Build` 43.3 + `Workspace tests` 29.2 ≈ 72.5 min after Quick Checks. This is the wall clock.
+2. **Connect Feature Boundaries (parallel near-critical):** median 53.5 min on its own lane with `CARGO_BUILD_JOBS: "2"` limiting build concurrency on the credential-test step; becomes the tail when the lint chain is fast.
+3. **Duplicate compilation across lanes:** `Workspace Lint and Build` builds workspace test binaries; `Build RustFS Debug Binary` separately builds the debug binary + E2E binaries on another runner; Connect builds again. `cache-save-if: 'false'` on the Connect lane means that lane never warms the shared `ci-dev` cache.
+4. Runner queueing is small (28.43 queue-min vs 1379.72 runner-min in the complete half-day window) — not the bottleneck.
+
+## Gaps and caveats
+
+- Accounting windows: 2026-10-30T00–12Z collected 547 attempts but is flagged incomplete; 2026-10-30T12–24Z collection did not finish (timeout) and has no report; 2026-10-31T12–24Z was empty at collection time. Occupancy figures are per-window partial sums and must not be summed as a bill.
+- No CI workflow or selection change was made in this pass; strict gate semantics unchanged. No savings are claimed. Candidate fixes (build-artifact reuse between lanes, enabling cache save on the Connect lane, finer affected-selection granularity in shadow mode per ci-timing.md) are **unmeasured proposals**, not results.
+- Timing data alone does not establish functional coverage or escaped-regression rate; the 15–20 min target remains an experiment that currently misses by a wide margin.

 `scripts/ci_merge_queue.py` prepares a bounded queue proposal from a live ruleset snapshot without calling a mutation API. It preserves all existing checks, reviews, bypass actors and branch conditions, adds an `ALLGREEN` squash queue with at most two concurrent builds/two merged entries, and produces the original rollback payload. Its timeout accommodates the existing full gate while measurements are collected. API fields follow [GitHub's ruleset contract](https://docs.github.com/en/rest/repos/rules).
