Outcome

Hermes rebuilds now preserve every supported operator-managed config key recorded through nemoclaw config set. Rebuild completion explicitly lists restored and dropped keys; the before-fix workflow lost all ten tested contract keys, while the fixed workflow restored all ten and reported none dropped.

Reason

Rebuild regenerated the sealed Hermes config with only NemoClaw's managed route. Operator settings such as memory binding, token limits, provider timeouts, delegation, approvals, private-URL policy, extra custom providers, and custom top-level keys disappeared silently.

Fixes #10495

Changes

  • Capture the effective values for audited Hermes config set dotpaths before sandbox deletion, while excluding NemoClaw-owned route fields.
  • Store the snapshot in a private, SHA-256-bound rebuild handoff so retry and recovery paths can authenticate it.
  • Merge operator values into the freshly generated managed route through the existing digest-checked Hermes config guard, re-read them for verification, and reseed dashboard policy afterward.
  • Report every captured key as restored or dropped at rebuild completion.
  • Allow operator siblings beside managed Hermes policy leaves while continuing to mirror only reviewed managed values into the dashboard profile.

The current requirement is deterministic preservation of the supported host-side config channel. The rebuild restore phase is the consumer. A direct workspace restore is insufficient because Hermes config is generated and sealed outside the workspace snapshot. Unit, integration, tamper, cleanup-retry, managed-route, dashboard-policy, and live E2E checks protect the mechanism.

Verification

  • Before-fix real CLI E2E on yimoj-colossus-dev, sandbox h10495-isolated, gateway port 20498 — reproduced loss of all ten contract keys after a successful --force --verbose rebuild; completion reported no restored/dropped inventory.
  • After-fix real CLI E2E on yimoj-colossus-dev, sandbox h10495-pass, gateway port 20498 — rebuild exited 0; Hermes load_config() preserved all ten contract keys; dashboard policy converged; gateway restart and inference health passed; completion listed all ten restored keys and Dropped Hermes operator config keys: none.
  • npm run typecheck:cli — passed.
  • npx vitest run src/lib/actions/sandbox/rebuild-durable-config.test.ts src/lib/actions/sandbox/rebuild-restore-phase.test.ts src/lib/actions/sandbox/rebuild-post-restore-phase.test.ts src/lib/state/sandbox-manifest-publish.test.ts test/agents/hermes/seed-hermes-dashboard-config.test.ts — 5 files passed, 120 tests passed.

  • npm run checks:repository — passed.
  • npx vitest run test/e2e/support/workflow-plan.test.ts — 1 file passed, 86 tests passed.
  • npm test — aggregate failed only in host/tooling classes reproduced on the exact base: shared portable-host lock contention, ambient corporate CA state, shared forward/gateway authority, unsupported host npm 10.9.3, and compiled debug/redactor environment. Focused changed paths pass; evidence is recorded in the local unrelated-failure receipt.
  • Pre-commit, commit-msg, and pre-push hooks — passed.
  • GPG signature — verified locally with a good signature from Yimo Jiang (NemoClaw signing) <yimoj@nvidia.com>.
  • Diff secret scan — pre-commit gitleaks and private-key checks passed; the diff contains no secrets, API keys, or credentials.

Review notes

This changes sealed Hermes config restoration and was reviewed in repeated fresh-context correctness/security, validation, and maintainability passes until all three returned clean. Public changelog/docs updates are deferred to the repository's post-merge docs catch-up workflow.

📝 Walkthrough

Walkthrough

The rebuild flow captures selected Hermes operator configuration in a validated, digest-bound snapshot handoff. Restore verifies applied values and reports restored or dropped keys. Dashboard policy validation now operates at managed dotted-path level.

Move audit-file I/O out of the action module.

readHermesConfigSetKeys combines filesystem access with snapshot policy logic. Move bounded audit-file reading to the state or audit boundary. Keep this action module focused on rebuild orchestration and snapshot decisions.

As per path instructions, “actions orchestrate” and “state modules own persisted files and state I/O.”

2654-2749: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚖️ Poor tradeoff

Consider extracting the shared handoff lifecycle.

writeHermesOperatorConfigHandoff and clearHermesOperatorConfigHandoff duplicate writeRebuildPolicyHandoff (Line 2566) and clearRebuildPolicyHandoff (Line 2618) almost line for line. The only differences are the manifest field name, the filename prefix and extension, the agent-type gate, the size gate, and the error text.

A parameterized internal helper would keep one implementation of the create-publish-supersede and retire-delete-clear orderings. Both orderings are security-relevant, so a future fix to one copy must not miss the other.

This is a maintainability suggestion. The current behavior is correct.

Requesting changes before merge:

  • Fail safely when the NemoClaw metadata provider key is missing or invalid. The current cleanup path can retain managed provider fields, including credentials, in the preserved Hermes configuration.
  • Do not let an unsupported key in append-only audit history block every future rebuild. Preserve supported keys and report unsupported keys as dropped.
  • When a handoff has an invalid digest or schema, report the intended keys as unknown or dropped instead of returning an empty successful-looking restore report.
  • Make array verification account for multiplicity; one actual element must not satisfy duplicate expected elements.
  • Resolve the action-layer I/O ownership concern and strengthen the restore test to assert exact restored configuration values.

The six unresolved review findings remain applicable to the current head. No merge conflict was detected against the latest main.

Pushed follow-up fix commit 1ee4febdb082a3d514085a06d0badf8a1676dc70 for the requested changes.

The repair now:

  • derives missing Hermes provider keys before stripping managed route fields and fails closed when provider identity is unavailable;
  • reads operational audit state through the state-owned stable, no-symlink bounded reader;
  • reports syntactically valid unsupported operator keys as dropped instead of blocking every rebuild;
  • preserves dropped-key inventory even when a handoff fails digest/schema validation; and
  • verifies array multiplicity with bounded polynomial matching.

Local validation on the exact pushed commit: 85 focused tests passed, CLI typecheck passed, commit hooks passed, and the mandatory pre-push typecheck passed. CI and automated review are now running.

Addressed the latest review finding in 4c6cd555e.

  • Replaced the unbounded descriptor readFileSync with a read loop capped by the already-validated file size (maximum 8 MiB).
  • Retained post-read identity/size/time validation and now also reject short reads.
  • Added a deterministic regression where the audit file grows after the initial fstat; the reader requests only the validated byte count and fails closed on the changed identity.

Validation:

  • operational audit tests: 3/3 passed
  • codebase growth guardrails: 33/33 passed
  • CLI typecheck passed
  • commit hooks and mandatory pre-push checks passed

The current CI assertion-census failure on the preceding head is unrelated to this PR and reproduces from the current base (hermes-discord.test.ts budget drift).

## Outcome

Managed-provider recovery and snapshot cloning now use the typed
OpenShell provider adapter for provider reads, profile imports, and
provider creation. Existing recovery, reconciliation, and fail-closed
behavior stays intact; destructive provider cleanup remains in Slice 8.

## Reason

Issue #9806 is moving managed-provider consumers behind one typed
protocol boundary. Recovery and clone paths still owned raw OpenShell
provider commands and duplicated diagnostic parsing, which left those
flows outside the adapter contract completed in the earlier slices.

### Related issues

Part of #9806

## Changes

- Add a managed-provider adapter factory so rebuild and snapshot
consumers share the selected-gateway target and typed CLI adapter.
- Route rebuild provider registration and recovered credential metadata
checks through typed provider reads, preserving selected runtime
authority at the delete edge.
- Route snapshot clone inspection, profile import, and provider creation
through the adapter while retaining exact reconciliation and ownership
checks.
- Keep rollback inspection and deletion on the existing raw path for
Slice 8.
- Preserve bounded, suppressed provider-create diagnostics in the CLI
adapter and protect the behavior in its unit test.

## Verification

- Focused CLI recovery, snapshot, gateway teardown, and provider-export
contracts - 208 tests passed on the final source revision.
- Focused integration recovery, reconciliation, and provider-export
contracts - 3 tests passed and 2 platform-inapplicable tests skipped on
the final source revision.
- Current-main dashboard, WeChat install, and managed-image bundle
contracts - 69 tests passed on the final source revision.
- `npx vitest run --project package-contract
test/package-contract/cli/credentials-cli-command.test.ts` - 26 tests
passed on the final source revision.
- `npx vitest run --project integration
test/agents/hermes/hermes-image-build-probes.test.ts` - 57 tests passed
on `73eacfee5c`.
- `npm run build:cli` - passed.
- `npm --prefix nemoclaw run build` - passed.
- `npm run typecheck:cli -- --pretty false` - passed.
- `npm run validate:pr` - passed on `73eacfee5c` against canonical main
`f893b8359e`.
- `npm run review:local` - unavailable because the temporary OpenShell
review gateway refused connections; no local Advisor result is claimed.
- The diff contains no secrets, API keys, or credentials.

## Review notes

Slice 6 merged in #11234. This revision integrates canonical `main`
through `f893b8359e` and leaves only the 20-file Slice 7 recovery,
snapshot, and adapter-ownership documentation diff. Mainline PRs #11314,
#11327, #11298, #11332, and #11338 resolved the inherited cache-seed,
gateway teardown mock, Hermes image-pointer and probe-digest, dashboard,
WeChat, and image-bundle contract failures observed on earlier
revisions.

The complete CodeRabbit review for `be4b1de3e1` reported three related
cutover findings. This revision addresses all three by injecting the
adapter in the preparation proof, documenting the bounded raw cleanup
bridge and Slice 8 exit criteria, and sharing the adapter
credential-name predicate with clone preflight. The resulting CI fixture
fallout was repaired across the complete affected root-cause group.

The incremental CodeRabbit review for `49ce5d9032` reported two
comments. The adapter already provides the sole credential-name
validator, so that comment required no change. The missing-provider
process fixture now asserts its status and exact stderr contract.

The incremental CodeRabbit review for `cb788fe0f0` reported an orphaned
Hermes handoff on a pre-delete bailout. Canonical main commit
`7c54bc084a` introduced every reported line in #10780. Slice 7 changes
only the later provider inspection await, so this finding is inherited
and requires no Slice 7 change.

The complete PR Review Advisor run 34367204068 reviewed commit
`cc647e8`. Seven specialists found no required change. The architecture
specialist requested typed destructive cleanup, which is the accepted
Slice 8 boundary and is not part of Slice 7. The reduction specialist
suggested removing the managed-provider facade. The facade remains
because three current recovery consumers use it to bind the
selected-gateway policy and Slice 8 is its next current consumer.

The complete exact-head PR Review Advisor run 34405962090 reviewed
`2cfcae6b38`. Its documentation specialist found the OpenShell adapter
README still described the former ownership model; `73eacfee5c` applies
the requested paragraph-only correction. The architecture, migration,
and reduction specialists each requested the same typed
destructive-cleanup cutover. That work is the accepted #9806 Slice 8
boundary and is implemented in stacked PR #11328, so it does not require
a Slice 7 production-code change. The other five specialists found no
required change.
