What does this PR do?

Rehydrates replacement native-eval leases before dispatch.

Why?

The controller previously treated an old bootstrap timestamp as proof that a
new lease contained the runner. Recovery could then fail before the harness
started, producing a false benchmark failure.

Fixes #55

Changes

  • record the exact bootstrapped_lease_id
  • reuse bootstrap state only when it matches the active lease
  • add a regression test for recovery with an old timestamp and replacement lease

Live proof

Recovered a legacy OpenClaw run whose manifest had an old bootstrap timestamp
but no bootstrapped_lease_id.

  • rebound the run to its active replacement lease
  • performed the full native-runner bootstrap on that lease
  • persisted the exact active lease as bootstrapped_lease_id
  • dispatched the OpenClaw harness successfully
  • exported a verified final artifact with 4/4 completed results
  • run exit code: 0

This is the exact recovery state the regression test covers; the controller no
longer trusts timestamp-only bootstrap state.

Tests

  • 40 focused fleet tests pass
  • Python 3.11 and Python 3.12 CI pass
  • Ruff passes on the touched files
  • fresh Codex autoreview reports no actionable findings
  • live replacement-lease recovery completes a four-task OpenClaw run

ClawSweeper review

What this changes

The PR records the lease ID used to hydrate a native-evaluation machine and rehydrates a replacement lease before dispatching recovery work.

Regression provenance

Possible regression — probable (reviewed change; failure trace). No predecessor PR is attributed.

Merge readiness

⚠️ Ready for maintainer review - 3 items remain

Keep open: current main still uses timestamp-only hydration, while this MEMBER-authored PR is the focused candidate fix for the linked open recovery report. No concrete patch defect was found; maintainers need to accept the deliberate one-time hydration for legacy manifests.

Measure Result What it means
Overall readiness 🐚 platinum hermit (4/6) The repair is narrow, source-backed, and regression-covered; the remaining question is the explicit legacy-recovery operating trade-off.
Proof confidence 🐚 platinum hermit (4/6) Not applicable: This MEMBER-authored PR is exempt from the external-contributor proof gate; its body nevertheless documents an after-fix recovery through final artifact verification.

Verification

Check Result Evidence
Real behavior Not applicable Not applicable: This MEMBER-authored PR is exempt from the external-contributor proof gate; its body nevertheless documents an after-fix recovery through final artifact verification.
Evidence reviewed 4 items Current main remains affected: Current main decides hydration from bootstrapped_at_utc alone and contains no stored lease-ID comparison.
Focused recovery invariant: The PR compares the active lease with bootstrapped_lease_id and persists that ID only after hydration.
Regression coverage: The added test models a timestamp-only legacy recovery, asserts replacement-lease hydration, dispatch, and persistence of the active lease ID.
Findings None None.
Security None None.

Live Verification

How this fits together

ShellBench’s native-evaluation fleet controller resumes benchmark runs on remote Crabbox leases. It reads a persisted manifest, prepares the active machine when needed, dispatches the harness, and records verified results.

Decision needed

Question Recommendation
Should recovery prioritize safe rehydration over avoiding one additional hydration for legacy timestamp-only manifests? Accept safe legacy recovery: Merge the PR and allow timestamp-only manifests to hydrate once before dispatching a replacement lease.

Why: The patch intentionally changes persisted-manifest recovery behavior, so maintainers own the resulting provider-cost trade-off.

Before merge

  • Resolve merge risk (P1) - Legacy manifests that only have bootstrapped_at_utc will perform one full hydration during their next missing-run recovery, adding bounded setup time and provider cost.
  • Complete next step (P2) - This MEMBER-authored PR has no mechanical repair finding; maintainers need to decide whether to accept its intentional legacy recovery behavior.

Metric Value Why it matters
Patch scope 2 files affected; production +3/-1, tests +29/-0 The implementation changes one recovery decision and directly covers the legacy replacement-lease case.

Root-cause cluster

Relationship: fixed_by_candidate
Canonical: #55
Summary: This PR is the concrete candidate fix for the linked replacement-lease recovery bug.

Members:

Proposal only: this assessment does not dispatch repair, suppress jobs, mutate sibling items, close, or merge anything.

Merge-risk options

Maintainer options:

  1. Merge with bounded legacy hydration (recommended)
    Accept the one-time setup cost for timestamp-only manifests so recovery cannot dispatch against an unprepared replacement machine.
  2. Pause for migration policy
    Defer the PR if maintainers require an explicit legacy-manifest migration or operator-facing recovery notice first.

Technical review

Best possible solution:

Accept the lease-ID invariant and merge the focused repair, retaining safe one-time hydration for legacy manifests.

Do we have a high-confidence way to reproduce the issue?

Yes—the linked report and focused test define a timestamp-only recovery manifest that obtains a replacement lease; this read-only review did not execute it.

Is this the best way to solve the issue?

Yes—the active lease ID is the missing identity needed to distinguish stale bootstrap metadata from a prepared active machine, and the change is confined to recovery.

Labels

Label changes:

  • remove proof: sufficient: Current real behavior proof status is not_applicable, not sufficient.

Label justifications:

  • P2: An unprepared replacement lease can cause false native benchmark failures, but the affected recovery path is limited.
  • merge-risk: 🚨 compatibility: Timestamp-only manifests created before the new field will receive a newly required hydration on their next missing-run recovery.
  • rating: 🐚 platinum hermit: Overall readiness is 🐚 platinum hermit; proof is 🐚 platinum hermit and patch quality is 🐚 platinum hermit.
  • status: 👀 ready for maintainer look: ClawSweeper has no concrete contributor-facing blocker left for this PR. Not applicable: This MEMBER-authored PR is exempt from the external-contributor proof gate; its body nevertheless documents an after-fix recovery through final artifact verification.

Rank-up moves

Optional improvements that raise the rating; they are not merge blockers.

  • Confirm that the bounded one-time hydration cost for legacy manifests is acceptable.

Overall follows the weaker of proof and patch quality.
Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.
