The
catch {}block keeps the session authoritative, which is the correct fail-closed choice. It also hides every reason the record cannot be rebuilt. An operator sees a permanently blocked different-name run without any signal.Log the failure cause at warn level, or add the reason to the recovery message surface, so the blocked state is diagnosable.

verifyCreatedSandboxBeforeEffectsdeclarescreateAttemptNonce: string(Line 212). The three call sites use a non-null assertion, and the three cases differ:

createAttemptNonceisnullwheneverdeferPostCreateEffectsis false, because Lines 406-409 only generate a nonce for the deferred path. The call passesnullunder astringtype. It is currently harmless only because Line 216 returns early wheninput.verifyCreatedSandboxBeforeEffectsis undefined.Line 696 depends on an invariant that the signature does not state. Guard the nonce before the call, or widen the parameter to
string | nulland keep the early return as the single authority.♻️ Suggested guard at the managed-bootstrap call site

runSandboxProviderPreDeleteCleanup so its options also pass the selected
verifiedPolicyRevalidation callback as revalidateSandboxIdentity, matching the
existing provider-cleanup path and preserving per-detach identity checks.
In `@src/lib/state/onboard-session-cross-process-lock.test.ts`:
- Around line 128-160: Update the test around loadSession and its
fs.readFileSync spy so it matches the numeric descriptor used by the pinned
read, allowing the directory swap to execute before reading and restore
afterward. Declare originalRename before the mock closure so the callback cannot
access it before initialization, and assert the session value guaranteed by the
descriptor-based read after replacement.

Reviewed latest PR commit 647f425b7483d232ba447fd6867579963a908b91 against base SHA fe75bcd82211d99f3c11c7c8a08585c34e71fff1. I am requesting changes for the unresolved identity-bound cleanup defect in the existing review thread: #10510 (comment)
runProviderPreDeleteCleanup performs one authority check, then detaches providers without passing verifiedPolicyRevalidation as revalidateSandboxIdentity. A same-name sandbox replacement between detach operations can lose provider attachments. Pass the callback through and add a regression test that changes the sandbox identity between detach operations and proves the next detach is refused.
After this finding is resolved, approval is contingent on every required check passing for the same latest PR commit.

Reviewed latest PR commit 2137b5b7032dff26d4ab389c87def468abd9cf1a against base SHA d0d5120cc6d574a5575b322b79b7cd49ca7c269d.
The prior blocking identity-bound provider-cleanup defect is resolved. runAuthorityBoundProviderCleanup now supplies the exact identity revalidator to runSandboxProviderPreDeleteCleanup, which applies it before and after every detach. The new regression changes identity between detach operations and proves the next detach is refused. Both earlier review threads are resolved. All commits are verified, the current CodeRabbit pass found no actionable issue, and the current nine-category security review found no blocking defect.
Required checks are still pending, so this Comment is not an approval. The favorable code and security assessment is contingent on every required check passing for this same latest PR commit.
Non-blocking: the PR Review Advisor correctly notes that the alternate-name documentation applies only when NemoClaw saved the independent recovery record. Qualifying that command would keep an operator from following an unavailable path after a recovery-record persistence failure. Please handle that as a narrowly scoped follow-up issue or documentation PR.

Outcome
Retained sandboxes now keep their exact post-create authority across verification failures, retries, process restarts, and concurrent state changes. Provider, credential, policy, cleanup, and onboarding-session operations refuse same-name replacement or substituted state before crossing their mutation boundary.
Reason
The security follow-up review on merged PR #10396 identified seven composition gaps that its original outer-boundary tests did not exercise. This follow-up closes only those gaps while preserving the accepted behavior from issue #9833.

This PR adds public-process, concrete generic-boundary, filesystem-race, and two-process recovery probes at those enforcement points.
