Recovery reports include workload assessments and observation gaps.
REST requests retry transient responses and transport failures only for replayable, idempotent operations.
Bug Fixes
Explicitly select the WebAssembly compilation target for browser builds.
Storage integration tests wait for the service to become ready before running.
Breaking Changes
Recovery state is tied to its full configuration. Use a new state location or provision a separate job when changing configuration; legacy reports retain their restart budget and are archived in the new context.

Walkthrough
This pull request adds configurable recovery-supervisor resilience, including state restoration, hub reconnection, dependency checks, and restart controls. It also updates mise platform configuration and version pins, routes native REST requests through shared retry handling, and improves S3 test readiness.
The runtime restores supervisor state, observes dependencies, and retries hub registration when reconnect is enabled. Kubernetes access and readiness checks distinguish supervised workloads from dependencies. Tests cover reconnection, dependency health, and access permissions.
Tool declarations now use platform filters for GnuPG, Windows prerequisites, OpenSSL, and libclang. Windows ARM64 config sets lockfile_mode = "merge". The LLVM MinGW asset pattern is defined in .mise/config.toml. Browser WASM tasks use web_cargo_args and pass the browser target.
Mise policy and version requirements config/conftest/policy/mise/*, CHECKS.md, config/jscpd-baseline.json, .github/actions/install-mise/action.yaml, .github/workflows/docker-windows.yaml, Dockerfile, README.md, services/*/Dockerfile, utilities/cli/src/deployment_types/scenario_image.rs, verification/local/output/*/Dockerfile, CHANGELOG.md
Policy rules and tests constrain merge lockfile mode and specified OS-scoped tools. Mise pins and documented minimum versions change to 2026.10.20.
The generated native client delegates request execution to crate::retry::execute. The changelog describes bounded retries for specified transient responses and transport failures, and lists exclusions.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Enable the health endpoint for the test server.
If the parent environment sets RUSTFS_HEALTH_ENDPOINT_ENABLE=false, start_rustfs inherits it and this poll cannot succeed. The test then fails after 30 seconds even if S3 is ready. Set the variable to true on the spawned command. (raw.githubusercontent.com)

services/recovery-supervisor/src/policy.rs:369 Major · Stability & Availability · Heavy lift
Future saved_at values block startup, and zero downtime delays deadline expiry.
restore returns RecoveryError::HealthClock when saved_at is later than the wall clock. load_supervisor returns that error unchanged, and startup propagates it with ? before it persists any state. The state file therefore stays as it was, and each restart fails the same way until the clock passes saved_at. The restore path does not document this as intended behavior.
Treating downtime as zero avoids the startup failure, but it is not neutral. The restored clock starts from elapsed_seconds alone, so it runs behind the real elapsed time. Recovery deadline checks compare the current time with an incident.onset saved before the restart. A lower current time delays deadline_seconds expiry. The supervisor can then keep attempting recovery past its configured deadline. The cooldown check moves the other way: a lower current time makes it stricter, so cooldown is not skipped.
Choose the behavior explicitly:
Fail closed. Document the rule, and return an error that names the future saved_at value. Recovery then requires a correct clock.
Keep startup running. Use a fallback that does not understate elapsed time, and confirm that deadline expiry still uses the correct time base after restore.

Update the restore logic that calculates downtime from snapshot.saved_at to
explicitly fail closed when saved_at is in the future: return a RecoveryError
that includes the future timestamp, and document that recovery requires a
correct system clock. Keep deadline calculations based on the restored time
without substituting zero downtime.
