Outcome

Restore Hermes gateway readiness when a persisted or migrated sessions directory 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 main failed 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 left sessions unchanged.

E2E root cause: Hermes root-entrypoint / restored sessions state is not writable by gateway
Source run: https://github.com/NVIDIA/NemoClaw/actions/runs/33609216679 (attempt 1)
Failed job: sandbox-images-and-e2e / test-hermes-sandbox-image (https://github.com/NVIDIA/NemoClaw/actions/runs/33609216679/job/100182707399)
Signature: SQLite session store is read-only; sessions.json raises permission denied; health never becomes ready
Scope: one root cause

Changes

  • Initialize sessions as gateway:sandbox 2770 in both Hermes image layouts.
  • Repair restored sessions, gateway, and runtime state through one ordered, no-follow, descriptor-verified startup boundary.
  • Refuse symbolic-link and file substitutions for each state directory, prove refusal leaves the object and symlink target unchanged, and provide safe trusted-snapshot recovery guidance for directories and .hermes_history.
  • Keep .hermes_history as gateway:sandbox 0660 in root-separated images. Non-root startup leaves an already-correct mode untouched, while root startup reasserts the protected owner and mode through the opened inode; the sandbox group retains append access.
  • Isolate every root-phase inline Python helper with python3 -I, and make the live root-entrypoint test prove a hostile inherited PYTHONPATH cannot execute sitecustomize as root.
  • Replace root log repair's os.walk and absolute child opens with traversal anchored to verified no-follow directory descriptors. Each child inode and file link count is verified before fchown or fchmod, and path identity is rechecked afterward.
  • Emit a stable logs directory layout-refusal event, retain it in bounded managed diagnostics, document the trusted-snapshot recovery path, and prove a replaced log-directory link leaves an external sentinel's owner, mode, and content unchanged.
  • Fingerprint hostile test fixtures through one O_NOFOLLOW file descriptor, removing the prior CodeQL check/use race.
  • Consolidate unsafe state-directory coverage into the existing Hermes startup harness and remove Dockerfile-fragment replay tests; the real image/root-entrypoint lane owns the final layout boundary.

Verification

  • Pre-fix: focused sessions-permission regression failed with mode 750, expected 2770.
  • Affected Hermes integration sweep — 146 tests passed across the 6 changed integration files after the runtime and diagnostic changes, including deterministic post-validation swaps for the config root and all three auxiliary directories plus host-visible failure diagnostics.
  • npx vitest run --project integration test/runtime/sandbox/sandbox-provisioning.test.ts --sequence.concurrent=false — 55 tests passed after removing two Dockerfile-source assertions.
  • The real-image hermes-root-entrypoint-smoke suite verifies root membership in the sandbox group and imports every module supplied by the selected Hermes extras, including HermesACPAgent, from the built image.
  • npx tsx scripts/checks/e2e-mock-parity.mts --base origin/main --head HEAD — passed.
  • npm run test:projects:check — exact membership across 7 projects and 2,650 candidates.
  • npm run test-size:check, npm run source-shape:check, npm run checks:repository, and npm run typecheck:cli — passed. Both changed legacy test files remain within their 1,500-line budgets.
  • npm run docs — passed route and Fern validation with zero errors.
  • npm run validate:pr — pre-commit, commitlint, and pre-push checks passed on exact head 57391f2e60c5affe25beb7e540f0f5522aef8d67, based on upstream main d8e90d5bd386d852a24611c1034913fb2a957079.
  • Commit hooks also passed ShellCheck, hadolint, secret scanning, semantic E2E phase plans, repository checks, and growth guardrails.
  • GitHub commit verification — exact head 57391f2e60c5affe25beb7e540f0f5522aef8d67 is Verified and contains upstream main d8e90d5bd386d852a24611c1034913fb2a957079.
  • Diff reviewed for secrets, API keys, and credentials — none present.

The local live-image attempt stopped in a stale legacy Docker cache before changed code executed (NODE_VERSION=24.16.0 cache state compared with the reviewed 24.18.1 checksum). Exact-head hosted builders use clean inputs and own the operational root/container evidence.

Review notes

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 0660 is already correct, allowing the image to retain the protected gateway:sandbox owner.

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 head bac482862 addressed both with descriptor-anchored traversal, an unchanged external-sentinel regression, and the stable logs directory event. 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. Head eb51dd22f completed 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 head 67cb064a5 anchors 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 head b3715db4f validates current-or-gateway ownership plus the sandbox group when the deployed account pair exists, adds a live sandbox:root 0660 refusal case that remains openable by the current user, names /tmp/nemoclaw-start.log and NEMOCLAW_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 head f19fa9a52 keeps 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 GHCR toomanyrequests image-pull failure before analysis; the failed-job-only retry completed with no Operations finding. Exact head ef2b581b4 supplies 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 %q spelling. 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. Commit 5e67b2131 forces 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 head f1d561e16 then refreshed the branch from upstream main 19bb9860a; 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 head d34af50b7 preserves 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 value 1 survives while unlocked and is forced to 0 while 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 head b9dec567b removes 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-data cleanup 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. Commit 4f3ea22f0 opens each mutable layout directory through verified no-follow descriptors, applies ownership and mode only with fchown and fchmod, and rechecks the named inode. Unit coverage swaps both the config root and hooks immediately before mutation, while the real root-entrypoint target swaps the config root immediately before fchown; both require startup refusal and prove the external target unchanged. Merge head 31cc8636b refreshes the branch from upstream main e01658ed8, 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 9b78fddd3 adds those events, host extraction, recovery documentation, and regression coverage for all four resources. 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 stat -f %Lp omitted the special bits while GNU stat -c %a reported the full 3770. Commit 949c53f4c reads the full mode through isolated Python on both platforms and proves the API-key stage observes 3770. The six-file 146-test sweep and full PR validation passed afterward. The same CI run also had an unchanged OpenClaw Discord mock connection refusal; this PR does not alter that test or implementation.

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33671737736 completed all nine specialists. Eight found no required change. Its valid Code Reduction finding identified the repeated mutable-layout failure event and recovery text; commit de07d16d4 centralizes 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 rejects it(...) unit blocks under test/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 6a64b145d: eight found no required change, while Test Design identified that the root-entrypoint config-root race wrapper was unreachable because startup resets PATH before repair. Exact head 5974090b2 places the controlled wrapper at the actual python3 command path selected by startup’s fixed path, preserves the real interpreter beside it, and keeps the full startup-failure, injected-symlink, external-metadata, content, and diagnostic assertions.

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33676299457 completed all nine specialists on exact head 5974090b2 with no required change. Test Design specifically confirmed that the root-entrypoint swap case now reaches the deployed boundary and observes both refusal and preservation of the external target.

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33683182932 completed all nine specialists on e5e154e02. Eight found no required change. Test Design correctly identified two remaining Dockerfile-source assertions for selected Hermes extras and root group membership. Commit e154de5ec removes those extracted-source tests and moves both contracts to the existing real-image root-entrypoint target, which inspects the built image directly.

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33687427299 completed all nine specialists on 4450a478a. Eight found no required change. Test Design identified that the mutable-hash reconciliation test mocked every collaborator and asserted a call trace. Commit 5500d4537 replaces that trace test with positive and failure-path behavior tests through the real non-root preparation and integrity-state boundaries.

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33688706497 completed all nine specialists on 9590b820c. Eight found no required change. Test Design identified that one live root-entrypoint test ran seven independent scenarios behind a title naming only two. Commit d5a4d9735 gives all seven scenarios separate behavior titles and artifact declarations while retaining one shared image build.

Advisor run https://github.com/NVIDIA/NemoClaw/actions/runs/33692125961 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; commit cc1a23ade removes 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 with O_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 57391f2e6 contains upstream main d8e90d5bd. 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, and npm 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 nim_service resolver failure occurred in unchanged main-owned policy planning; neither executed this repair.

📝 Walkthrough

Walkthrough

Hermes startup now uses isolated Python and descriptor-safe repairs for state directories, logs, and history. It rejects unsafe layouts, reports recovery guidance, and quarantines relaunches after refusal. Images, policy patches, diagnostics, tests, and E2E fixtures enforce the updated contracts.

Changes

Hermes startup integrity and recovery

Layer / File(s) Summary
Descriptor-safe filesystem repair
agents/hermes/start.sh
Startup validates directory, log, and history descriptors. It rejects symlinks, hard links, replacement races, and unsafe file types.
Recovery orchestration
agents/hermes/start.sh, test/agents/hermes/hermes-gateway-auxiliary-retry.test.ts, docs/reference/troubleshooting.mdx
Layout refusal returns a dedicated status and prevents automatic relaunch. Root gateway startup propagates failures across dashboard, gateway, health, auxiliary, MCP, and permission-restoration steps.
Image and managed-policy contracts
agents/hermes/Dockerfile, agents/hermes/Dockerfile.base, agents/hermes/patch-profile-policy-defaults.py, test/agents/hermes/hermes-dependency-review.test.ts, test/agents/hermes/hermes-profile-policy-defaults.test.ts
Images configure sessions ownership and setgid mode. Managed gateway-plugin profiles bypass incompatible owner-only directory enforcement.
Startup and E2E validation
test/agents/hermes/*, test/e2e/live/hermes-root-entrypoint-smoke.test.ts, test/e2e/mock-parity.json
Tests cover unsafe state, logs, history, layout swaps, migration, secret boundaries, gateway state, image capabilities, dispatcher configuration, and refusal scenarios.
Diagnostics and policy-apply validation
scripts/managed-gateway-control.py, test/inference/managed/managed-gateway-control.test.ts, test/e2e-test.sh
Diagnostics recognize all layout-repair locations. Apply tests use isolated policy fixtures and reject malformed policies before protected operations.
Qualification and test support
ci/pi-agent-qualification-v1-*.json, src/lib/agent/candidate-authority.ts, test/support/hermes-shell-harness.ts, test/runtime/sandbox/sandbox-provisioning.test.ts
Qualification references and receipt digests are updated. Shared Hermes test helpers gain locked-stat and fake-process fixtures. Obsolete provisioning checks are removed.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to d7bc3

Hermes may repeatedly relaunch after rejecting an unsafe filesystem layout instead of quarantining recovery, and the oversized-log refusal contract is not fully protected. Resolve these startup safety issues before merge.

162-166: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Use behavior-based assertions for Hermes permissions

These assertions lock the test to one Dockerfile continuation format and argument order. A harmless reformat can fail the test while check_metadata still enforces gateway:sandbox 2770. Replace them with an image-build or runtime check of effective ownership and mode.

- Around line 1644-1648: Update the final Hermes metadata checks around
check_metadata so they honor NEMOCLAW_DARWIN_VM_COMPAT=1: require
/sandbox/.hermes and its sessions, cron, and logs subdirectories to use the
Darwin-mode 3777/2777 permissions, while preserving the existing 3770/2770

- Line 1245: Update repair_directory to track traversal depth, enforce an
explicit maximum before recursing into child directories, and invoke fail() when
the limit is exceeded. Ensure excessive nesting is handled within the existing
diagnostic path rather than propagating RecursionError, while preserving normal
repair behavior below the limit.
- Around line 1160-1161: Update repair_managed_directory() and repair_file() so
os.fchmod() handles PermissionError in non-root mode only after exact mode and
the permitted ownership contract have been validated; otherwise invoke fail()
with the stable “[SECURITY] Refusing Hermes log repair because ...” diagnostic
instead of allowing a traceback. Preserve the existing root behavior and apply
the same handling consistently in both repair functions.

In `@test/agents/hermes/hermes-start.test.ts`:
- Around line 1428-1430: Update the data table for the live gateway process test
in it.each so each case is a single-element tuple: use one tuple containing
undefined and another containing the argv array. Preserve the existing callback
signature and runtime-state assertions while ensuring liveGatewayArgv always
receives the complete argv array.
- Line 97: Update the fixture assertions in the Hermes start test to verify that
the renamed original layout entry exists after each run, in addition to checking
the unchanged external target and nonzero status. Reuse the existing target and

- Around line 162-166: Replace the Dockerfile text and argument-order regex
assertions in the Hermes permissions test with a behavior-based image-build or
runtime check that verifies the effective ownership is gateway:sandbox and the
mode is 2770 for the relevant Hermes paths. Keep the check independent of
Dockerfile continuation formatting and command ordering, while preserving
check_metadata coverage.

748-748: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Use the resolved interpreter for the root-phase layout helpers.

The helpers at lines 748, 894, and 1041 invoke bare python3, while other security-sensitive helpers use _HERMES_PYTHON. Use "$_HERMES_PYTHON" consistently. Update the layout-swap test to override _HERMES_PYTHON instead of prepending a fake python3 through PATH.

Fixed the hosted shard regression in signed commit 71fc8e8a9: the dependency-review test now verifies both Darwin/Linux metadata assignments and the variable-bound final-image checks. The affected Hermes suites pass 79/79, with repository checks, Pi parity, and commit hooks green.

Addressed the PR Advisor operability finding on exact head d7bc3c5200e5fda65cfb3ca53249f1678e1f3ece:

  • retained-log repair now streams directory traversal and enforces a shared 4,096-entry ceiling in addition to the depth ceiling
  • a preflight traversal rejects oversized trees before repairing retained log-file modes
  • the regression test creates 4,097 retained entries, verifies the stable recovery diagnostic, and verifies the pre-existing log remains unchanged

Validation: Hermes startup suite 51/51; related suites 80/80; repository checks; growth guardrails 47/47; bash -n; Pi receipt parity; pre-commit and pre-push hooks. Commit signature is GitHub-verified.

2931-2931: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Propagate the layout-refusal status.

Line 2931 converts HERMES_LAYOUT_REPAIR_REFUSED_STATUS (78) into 1. recover_hermes_gateway_current_user then cannot distinguish a security refusal from an ordinary launch failure. It takes the retry path instead of quarantining automatic relaunch.

startup flow by asserting the process exits with status 78, then snapshot
metadata for the complete logs/curator tree (or every wide entry) before
execution and compare it afterward to verify no entries were mutated. Replace
the fixed agent.log mode assertion with snapshot-based comparison so the test
remains independent of the process umask.

Follow-up exact head f6b9fc0c2c2936e583d833caa45ba30cbc2d7d33 addresses the final usable Advisor documentation finding and CodeRabbit test-strength finding:

  • troubleshooting now distinguishes log capacity limits (trusted-host archive/removal, then retry) from unsafe paths (snapshot/recreate)
  • the regression harness carries production exit status 78
  • the wide-tree test compares before/after fingerprints for all 4,097 retained entries instead of assuming an umask-dependent literal mode

Exact validation: Hermes startup 51/51, repository checks, growth guardrails 47/47, shell syntax, Pi parity, pre-commit/pre-push hooks. GitHub verifies the commit signature.

Refreshed the branch to current upstream main a37ab0587 (including #11001, #10909, and #10999). Exact head is now ddbfa4b799f6f5315b1377f95904c6ac16c939ed, GitHub verifies every reconciliation/merge commit, and the PR is mergeable.

The #11001 live-E2E assertion ratchet exposed duplicated checks in hermes-root-entrypoint-smoke. The refresh consolidates health, gateway-log, process, and runtime-layout assertions at their existing boundaries; uses foreground Docker exit status for refusal variants; retains the live stable status-78 proof; and removes bearer/dashboard duplication already owned by focused lower-level contracts. The file is now within the current ratchet without hiding assertions in helpers or generated probes: 4 direct expectations, 29 assertion points, and 5 generated probe blocks.

The branch also carried an obsolete Pi receipt/authority override. Current merged Pi image inputs are byte-for-byte the qualified main inputs at f4249cd; restoring main receipts and authority removes that unrelated PR diff and makes source-parity validation pass without inventing new qualification evidence.

Validation on the refreshed tree:

  • live E2E assertion census: passed (1,888 direct expectations across 86 files)
  • assertion-census tests: 13/13 passed
  • PR live-E2E budget guardrails: 5/5 passed
  • semantic E2E phases: 138 tests across 88 files
  • Pi receipt refresh tests: 18/18 passed
  • candidate qualification tests: 4/4 passed
  • exact-tree CLI build and pre-push CLI typecheck: passed before the final clean merge of already-validated upstream perf(cli): reuse Hermes executable proof during recovery #10999
  • post-merge Pi parity, E2E assertion ratchet, and git diff --check: passed

Fresh exact-head CI and Advisor review are running now. @cjagwani, this is the requested main refresh; please re-review the new exact head when the checks settle.
