Pull request overview
This PR fixes rebuild snapshot backups for older OpenClaw sandboxes by preserving openclaw.json when the sandbox-user SSH transport cannot read the sealed mutable-config layout, by adding a narrowly-scoped privileged fallback capture path that still routes the captured bytes through the existing local snapshot sanitizer.
Changes:
- Added an internal
captureStateFilefallback hook to the state backup flow, invoked only when the SSH state-file read exits with status1. - Implemented a privileged, descriptor-safe capture for exactly
/sandbox/.openclaw/openclaw.json(copy strategy only) using the sandbox’s privileged execution lease. - Added/updated tests to cover both the managed privileged capture boundary and the SSH-denied → fallback → sanitized-backup path.

Maintainer review — privileged capture boundary still needs executable evidence
I reviewed the complete five-file diff, issue #9215 ask 1, the registered-sandbox privileged execution lease, state-file fallback, sanitizer, focused tests, current automated reviews, and PR text at latest PR commit 66c6545cbe8c4ac06221a90429598f4d7f8dd7d5. The repair is exact-path and exact-strategy scoped, retains the existing sanitizer, and does not create a new supported product surface.
Four blockers remain:
- Exercise the production privileged capture script. The current tests mock
dockerSpawnSync; they verify result parsing but never run the embedded descriptor code. Add a fixture that executes the production script against a safe regular file and against a symlink, hardlink, FIFO or directory, oversized file, and concurrent file or directory replacement. Every forbidden case must fail without returning captured bytes. - Refresh the documentation writer receipt. Check the required review box and replace the stale
535b00b4dmarker with66c6545cb.no-docs-neededremains correct because this restores the existing documented snapshot/rebuild contract. - Correct the generated release text. A missing config is reported as missing; it is not captured. Describe the fallback as capturing the declared OpenClaw config only after the ordinary SSH read has a permission-class failure. Classify this as a bug fix, not a New Feature, and remove the undefined “secure fallback” claim in favor of the concrete path, file-type, link-count, size, and stable-read controls.
- Refresh validation and required CI evidence. The body’s 23/23 count predates the protocol and diagnostic tests, and normal NVIDIA-runner validation has not run. Bind focused evidence to this commit and obtain the ordinary required current-commit checks. Do not dispatch credential-bearing live E2E from the contributor branch.
Security review: secrets and credentials, input validation, authorization, dependencies, error handling, cryptography and data protection, restrictive configuration, and production system security PASS. Security testing is BLOCKED by the missing executable boundary fixture.
I did not run local validation, approve, or merge.

LOC Reduction / Codebase Simplicity Review
Why this blocks
The only change since the prior no-finding head extracts a three-line loop into a one-use helper.
src/lib/actions/sandbox/snapshot/backup-authority.test.ts:81-87 defines expectOpenClawStateFilesRejected, and its only caller is at line 347. The commit adds 10 lines and removes 3, moving the assertion away from the sole test while adding seven net lines. It does not centralize reused behavior or remove any branching.
Refactor direction
Restore the inline loop at line 347 and remove the helper. Keep the three rejection assertions beside the lease and Docker non-invocation assertions whose behavior they establish.
Expected result
Preserve identical coverage with seven fewer lines and keep the complete rejection contract visible in its owning test.

LOC Reduction / Codebase Simplicity Review
Resolved at latest PR commit 9a15e6e189416d6c92592f79005094c811864aa0.
The one-use expectOpenClawStateFilesRejected helper and its type-only import are gone. The three rejection boundaries now use one it.each table, and each named row directly verifies the null result, no privileged lease, and no Docker invocation.
The change from the previously reviewed commit removes two net lines. The table uses five more lines than the original grouped loop, but those lines create independent named cases and apply the side-effect assertions to every boundary. I found no replacement LOC or codebase-simplicity blocker in the complete current diff.
This is a scope-limited follow-up, not an approval or a correctness, security, or CI review.

Maintainer security and documentation review: PASS; large change flagged This security-sensitive PR adds 681 lines and removes 14 across six files, for a net increase of 667 lines. Most of the increase is boundary and integration coverage, but the size still requires deliberate human review. Security review:
Documentation review: PASS. This restores the existing rebuild backup behavior through an internal transport fallback and adds no command, option, default, configuration, or supported workflow. No public documentation change is required. The PR description now records that result and describes the fallback as a bug fix with its concrete controls. All eight commits are GitHub-verified, the contributor DCO declaration is present, and there are no unresolved review threads. The remaining gates are the bounded CI retry, the advisor retry, and independent human approval with clearance of the standing change request. This review waives none of them. |

Merge-train blocker: required CI and independent human review remain incomplete The original normal CI run passed static checks, build/typecheck, installer integration, and 11 CLI shards. Shard 11 ended on the existing 5-second timeout in The primary PR Review Advisor completed with no blocking finding. The second-opinion lane failed its original analysis and was cancelled during its single retry without publishing an actionable finding. No further retry will be requested. This security-sensitive change is flagged at 681 additions and 14 deletions across six files, for a net increase of 667 lines. Security testing and documentation review now pass, all eight commits are GitHub-verified, the contributor DCO declaration is present, and no review thread is unresolved. A CI workflow owner must obtain a successful required shard and aggregate result for the current branch revision. Independent human review must also clear the standing change-request state. The PR cannot merge with an unsuccessful required context, and no admin bypass, broad rerun, or review waiver will be used. |

Security and documentation review: PASS
- Secrets and credentials: privileged output remains in memory, and the existing backup sanitizer removes credentials before the manifest is published.
- Input validation and data sanitization: the fallback accepts only the declared OpenClaw directory, file, and copy strategy. Diagnostics are bounded and redacted.
- Authentication and authorization: capture runs only through the existing privileged-execution lease and verified sandbox-container ownership.
- Dependencies: no dependency change.
- Error handling and logging: missing files use a fixed protocol; unsafe metadata, process failures, and races fail closed without exposing captured bytes.
- Cryptography and data protection: no new cryptographic scheme. Local backup files retain restrictive permissions and existing secret stripping.
- Configuration and security controls: the subprocess uses an isolated Python runtime, a sanitized environment, a 30-second timeout, and a 16 MiB data limit.
- Security testing: focused CLI and integration coverage passes 60 tests, including symlink, hard-link, FIFO, directory, size-limit, file-replacement, directory-replacement, permission-fallback, sanitization, and restore behavior. Repository validation also passes.
- System security: directory-relative, no-follow file access and before/after identity checks narrow file and directory replacement races. The fallback does not broaden Hermes or Deep Agents Code behavior.
No public documentation update is needed because this repairs the existing OpenClaw rebuild contract. The +681/-14 change is flagged as large; 418 added lines are boundary and integration tests. Contributor commits remain unchanged. The refresh commit is signed, signed off, and GitHub Verified.

Gate update The refreshed branch now passes every required repository check, including all 12 CLI shards, static checks, build and type checks, installer integration, DCO, commit lint, documentation parity, installer hash, and code scanning. All commits are GitHub Verified, the independent nine-category security and documentation review passes, and no review thread remains unresolved. The four items in the standing change-request review are implemented: production code runs against regular, link, special-file, oversized, and replacement fixtures; the documentation receipt and release classification are current; focused evidence covers 60 tests; and ordinary CI is green. GitHub still records that earlier human change request. Reviewer-routing policy does not allow me to dismiss it or choose a replacement reviewer, so authorized human clearance is the only remaining merge gate. |
Resolved on the current commit. The production privileged capture script now has executable boundary coverage for regular, linked, special, oversized, and concurrently replaced files; the documentation receipt and release text are corrected; and current CI passed those targeted paths. The remaining aggregate failure is the known unrelated shard 9 timeout/heap condition.
Summary
Preserve
openclaw.jsonwhen rebuilding an older OpenClaw sandbox whose sealed mutable-config layout is valid but unreadable through the sandbox-user SSH transport. The ordinary SSH path remains first; only its permission-class failure can invoke a bounded, descriptor-safe privileged read of the declared config file before the existing local secret sanitizer runs.Related Issue
