[P2] The command reference still says every relaunch quarantined result is repaired with $$nemoclaw <name> rebuild --yes, but this change adds HERMES_RUNTIME_PREPARATION_FAILED, which is intentionally recoverable after correcting the supported input and restarting the sandbox. That conflicts with the updated troubleshooting guidance and can cause operators to rebuild unnecessarily. Please update docs/reference/commands.mdx to distinguish restart-recoverable preparation failures from integrity, unsafe-layout, and crash-budget quarantines that require rebuild or sandbox recreation.
The prior filesystem-safety and credential-boundary blockers are resolved on commit cf2bc70a6d.

Register image cleanup at the final scenario boundary.
When NEMOCLAW_HERMES_TEST_IMAGE is unset, buildImageIfNeeded builds both tags once and stores a fulfilled localImageBuild promise. Each scenario has its own CleanupRegistry, so per-scenario image removal would delete the tags after the first scenario; later scenarios would reuse the fulfilled promise and can fail because the images are missing. Register removal only in the suite-level/final-owner cleanup, such as the non-root-history-owner-refusal scenario, and skip it for prebuilt images. This removes both tags after the full file without breaking image reuse.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
Fix the escape so the shell applies the 000 default.
The script literal starts with String.raw at Line 159, so String.raw keeps the backslash. The container receives code="\${code:-000}". Bash treats \$ inside double quotes as a literal $, so this line assigns the literal text ${code:-000} to code and discards the real HTTP status from Line 161.
waitForHealth then never matches "200" or "401". Every scenario that calls waitForHealth polls for HEALTH_ATTEMPTS iterations and throws Hermes health did not become ready.
Set the default only when code is empty, without an escape that survives String.raw.

The prior relaunch-recovery classification blocker is resolved on commit ba37319ae0. The remaining documentation failure was verified against the current Hermes log-tree repair path and troubleshooting procedure. Current CodeRabbit and all nine Advisor specialists completed; documentation preview and command-reference parity pass; DCO passes; and every commit is GitHub-verified.

[P2] Distinguish bounded log-tree refusals from unsafe-path failures. This sends every unsafe startup layout to sandbox recreation, but exceeding the 4,096-entry or 64-directory-depth limit reaches the same preparation/quarantine path while production directs the operator to archive or remove old logs from a trusted host-side recovery environment and retry. Following this wording can cause unnecessary recreation and loss of inaccessible state. Direct count/depth failures to trusted host-side log cleanup and a startup retry; reserve snapshot or recreation guidance for symbolic links, hard links, unsafe entry types, and paths changed during repair.

Requesting changes before merge. The prior command-reference recovery blocker is resolved on a8ea592. Two remaining code-local blockers are attached inline. Separately, the required E2E / PR Gate has not been scheduled for this candidate, and the branch is still based on afb2342 rather than current main; approval must wait for a fresh trusted PR qualification on a current base.
Focused validation: npm run docs passed; the two focused Hermes suites passed (58 tests); all nine PR Review Advisor reports were reviewed; CodeRabbit's literal-command suggestion was rejected because this shared source intentionally uses the documented $$nemoclaw generation placeholder.

[P2] Preserve the recoverable log-limit path in this quarantine diagnostic. When repair hits the maximum log count or depth, the preceding diagnostic tells the operator to archive or remove retained logs and retry, but this unconditional message says the sandbox must be recreated. That contradiction can trigger unnecessary recreation and state loss. Keep the cause-specific guidance through this final status—cleanup and restart for limits, recreation for unsafe paths—and cover the log-limit status-78 case.

Outcome
Restore Hermes gateway readiness when a persisted or migrated
sessionsdirectory is no longer writable by the separated gateway UID. Startup now repairs that directory through the existing descriptor-safe cross-UID boundary before Hermes opens its session store. Root startup also protects the shared Hermes history entry and prevents privileged log repair from escaping the Hermes state root.Reason
The Hermes image smoke on
mainfailed twice while the root entrypoint remained alive and the gateway process was running. Its log reported a read-only SQLite session store and permission denial for/sandbox/.hermes/sessions/sessions.json. Startup repaired the other cross-UID state parents but leftsessionsunchanged.E2E root cause: Hermes root-entrypoint / restored sessions state is not writable by gateway

An intermediate exact-head rootless run exposed that blindly reapplying mode to a gateway-owned history file breaks non-root startup. The final startup logic skips that mutation when mode
0660is already correct, allowing the image to retain the protectedgateway:sandboxowner.Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33632938787 found two additional blockers on
ad27e5774: root log recursion could follow a replaced intermediate link, and log refusal lacked a bounded host diagnostic and recovery event. Exact headbac482862addressed both with descriptor-anchored traversal, an unchanged external-sentinel regression, and the stablelogs directoryevent. Its final Advisor pass asked for nested-link coverage, consolidation into the existing startup harness, qualified documentation, and stable recovery diagnostics for mutable-root history refusal. Headeb51dd22fcompleted those items. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33639093552 then found that history repair still opened its mutable parent by absolute path and that hard-link tests did not exercise root-only metadata mutation. Exact head67cb064a5anchors history creation and verification to a no-follow config-root descriptor, proves a swapped parent leaves the external directory and sentinel unchanged, and extends the live root-entrypoint contract with history/log hard-link refusal and protected-inode owner, mode, and content checks. It also removes the flagged duplicate fake-proc helper and source-shape fixture test. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33643012566 then asked for an explicit non-root ownership/group invariant, the correct pre-gateway log location, and a test-title correction. Exact headb3715db4fvalidates current-or-gateway ownership plus the sandbox group when the deployed account pair exists, adds a livesandbox:root 0660refusal case that remains openable by the current user, names/tmp/nemoclaw-start.logandNEMOCLAW_START_LOG=..., and narrows the unit-test title. Its broader request to replace the established extracted-shell behavior harness was not applied: the repository source-shape checker reports zero source-shape cases and the tests execute filesystem/process outcomes rather than assert source text. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33645958177 then reported only a test-helper ownership blocker and a documentation wording suggestion; all other specialists were clean. Exact headf19fa9a52keeps the three single-suite layout fixtures private to the startup test, splits the independent shields-up runtime-env contract so the startup test remains below 1,500 lines, leaves only a real cross-suite stat shim in shared support, and clarifies the host-control failure wording. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33649490500 then found that the unlocked dispatcher case did not prove caller-value preservation and that the Hermes harness duplicated the canonical heredoc-aware extractor, shell quoting, and standard lstat behavior. Its Operations specialist initially hit a GHCRtoomanyrequestsimage-pull failure before analysis; the failed-job-only retry completed with no Operations finding. Exact headef2b581b4supplies a non-default unlocked value, re-exports the single canonical extractor, uses the production shell quote helper and direct no-entry lstat API, and verifies the emitted proxy env by sourcing it rather than asserting incidental Bash%qspelling. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33651758538 then found an inherited environment could re-enable the kanban dispatcher under Shields up, one unreachable locked-root branch, a self-derived MCP digest oracle, and an exact multiline startup-fragment test. Commit5e67b2131forces the dispatcher off for locked config, removes the dead branch, uses a fixed independent digest, and tests a named root-startup boundary through observable gateway state. Merge headf1d561e16then refreshed the branch from upstream main19bb9860a; the 162-test sweep and full PR validation passed again. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33655425553 then caught that root preparation could normalize the config root before real Shields-up detection, and that the extracted-function dispatcher suite did not prove the entrypoint boundary. Exact headd34af50b7preserves a detected locked root, removes that redundant source-extraction suite, and extends the existing fresh-image root-entrypoint target to inspect the launched gateway process environment: caller value1survives while unlocked and is forced to0while locked. The resulting 159-test sweep, zero source-shape budget, semantic E2E phase plan, and full PR validation passed. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33657949858 then identified a private read-count oracle in the MCP integrity test and missing special-entry coverage in the privileged log repair. Exact headb9dec567bremoves the private monkeypatch and count assertion while retaining the public current-state and race regressions, and adds a FIFO refusal case proving the special entry remains unchanged. Its broad helper-consolidation suggestion was not applied because the same Advisor run's Design/Architecture and Dependency specialists found that state directories, log trees, and the history entry have distinct ownership contracts and warrant separate repair paths. Its.hermes-datacleanup suggestion concerns pre-existing policy and plugin consumers outside this sessions-permission repair. Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33660170954 then found one remaining privileged pathname race in the older config-root and auxiliary-directory repairs; the other eight specialists were clean. Commit4f3ea22f0opens each mutable layout directory through verified no-follow descriptors, applies ownership and mode only withfchownandfchmod, and rechecks the named inode. Unit coverage swaps both the config root andhooksimmediately before mutation, while the real root-entrypoint target swaps the config root immediately beforefchown; both require startup refusal and prove the external target unchanged. Merge head31cc8636brefreshes the branch from upstream maine01658ed8, with 144/144 changed integration tests and full PR validation green.Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33666166768 found one Operations gap after the descriptor repair: config-root and auxiliary-directory refusals were not yet allowlisted in bounded host diagnostics or documented with stable per-resource recovery events. Exact head

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33669111411 then completed all nine specialists with no required change. Its Trust specialist initially received an external HTTP 403 before producing output; the bounded failed-job retry, attempt 2, completed cleanly.CI run https://github.com/NVIDIA/NemoClaw/actions/runs/33669117601 exposed one stale cross-platform test helper after the descriptor migration: BSD

Eight found no required change. Its valid Code Reduction finding identified the repeated mutable-layout failure event and recovery text; commit
de07d16d4centralizes those diagnostics without changing the stable messages. Its Test Design suggestion to split the single Hermes Discord live target was not applied: the repository assigns live execution to the typed target model, explicitly rejectsit(...)unit blocks undertest/e2e/live/**, and this target already publishes eight behavior-specific phases plus its artifact contract. The preceding exact-content Advisor run 33669111411 also found that organization appropriate.Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33674269273 completed all nine specialists on

ccb5a345d. Behavior, Architecture, Dependency, Documentation, Operations, Migration, and Trust found no defect. Test Design identified two remaining source-shape and full-call-trace tests; commitcc1a23aderemoves the Dockerfile-fragment executable checks, verifies the manifest path against the built image, and replaces auxiliary retry traces with outcome and bounded-count assertions. The same commit fixes exact-head CodeQL alert 2975 by opening the hostile history fixture withO_NOFOLLOW, verifying inode identity, and reading through the descriptor. Code Reduction requested one image-internal repair program for all four resource types; that was not applied because the Architecture and Dependency specialists independently confirmed that mutable directories, cross-UID state, recursive logs, and the single-link history file have distinct ownership, recursion, and hard-link contracts, with one existing orchestration and failure-reporting owner.Fresh exact-head evidence:
Exact head
57391f2e6contains upstream maind8e90d5bd. Local exact-head validation passed: 112 focused Hermes and provisioning tests, the separately rerun 59-test Hermes startup and auxiliary sweep, 139 semantic E2E phase contracts across 90 files, zero source-shape cases, 33 growth checks, CLI type-checking, repository checks, andnpm run validate:pr. Two unrelated OpenClaw fixture processes timed out once under local contention; their owning Hermes provisioning describe passed separately, and the same full 112-test set passed immediately beforehand. The linked fresh workflows are now exercising the built Hermes image and restored-session runtime paths.No focused Hermes Discord E2E was dispatched from this repair PR. The prior exact-head CI shard 10 failure was an Azure package-repository 403, and the prior self-hosted

CHAT_UI_URLPython-isolation regression, replacing a duplicate 207-line port/bootstrap harness. The same successful layout-repair test now explicitly proves that hostile inheritedPYTHONPATHcannot executesitecustomizethrough any of the five isolated Python repair helpers. Non-MCP preparation failures emit the fixed machine-readableHERMES_RUNTIME_PREPARATION_FAILED stage=<stage>shape and quarantine immediately. The host controller accepts a bounded stage slug instead of duplicating the producer's stage inventory, while malformed variants remain redacted. Troubleshooting separates repairable preparation failures (correct the input, then stop/start) from integrity or crash-budget quarantine that requires rebuild.Issue #6972 has no accepted product-scope decision for a locked-root Hermes compatibility surface and records the existing config-hash refusal as intended behavior. This head therefore removes the intermediate locked-root admission, dispatcher override, and canonical live scenario, preserving main's fail-closed unsupported-posture refusal. Root Python-isolation evidence remains in the supported mutable restored-state scenario, and hard-link refusal remains independently covered.
Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33961088085 completed all nine specialist reports. Its valid Documentation and Reduction findings are resolved. Its Operability proposal for a new auxiliary-failure budget, degraded-state protocol, ports diagnostic, and host recovery transition was not included because those loops are unchanged behavior on upstream main and no accepted requirement owns that separate product contract. Follow-up Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33961539827 found the documentation, reduction, operability, architecture, behavior, delivery, migration, and security areas clean. Its one Verification gap—the unasserted hostile-Python sentinel already returned by the successful repair harness—is resolved by the one-line exact-boundary assertion on this head.
Fresh local exact-head evidence: the 105-test affected Hermes startup, supervisor, auxiliary, managed-control, and hash sweep passes; the final 49-test startup owner passes with the new sentinel assertion; exact Vitest project membership across 2,597 files and the unchanged 1,882-expect live-E2E assertion ratchet pass; mock parity, semantic E2E phase plans, source-shape and growth guardrails pass; docs validation reports zero errors; and
npm run validate:prpasses the complete pre-commit, commitlint, and pre-push contract on exact head. This includes ShellCheck, Hadolint, gitleaks, repository checks, formatting/lint, CLI type-checking, and DCO. Hosted exact-head workflows are now exercising the freshly built Hermes image and root-entrypoint boundaries.Security review: PASS across authentication/authorization, input validation, injection, secrets, cryptography, dependencies, data exposure, configuration, and supply-chain categories. The repair paths use descriptor-relative no-follow traversal, inode revalidation, bounded recursion/entry counts, and fail-closed diagnostics.
