[P1][Security testing] The shipped Hermes Discord policy is Python-only here, but test/e2e/live/hermes-discord.test.ts:145-164 rebuilds its fake policy with /usr/local/bin/node and /usr/bin/node, then :686-716 performs the REST proof through sandboxNode. Impact: the live gate validates a wider authority than production and can stay green while the least-privilege contract is broken or unexercised. Smallest safe fix: remove both Node grants from the fake policy and replace the REST probe with /opt/hermes/.venv/bin/python (or the reviewed Hermes Python helper), preserving the placeholder, credential-binding, inspected REST/WebSocket, timeout, and token-isolation assertions. Regression: make the lane fail if Node is reintroduced or if the Python runtime cannot reach the credential-bound Discord route.

Addressed in commit 2bd37f0. The Hermes fake Discord policy no longer grants either Node binary. The WebSocket and credential-bound REST proofs both run through /opt/hermes/.venv/bin/python, and the live lane reads the effective policy and fails if Node appears in either the production or fake Discord policy. Focused policy/onboarding tests (125), Hermes E2E-support tests (4), CLI type-check, docs, and npm run validate:pr pass. Fresh exact-head hermes-discord E2E will be dispatched after normal candidate checks and reviews stabilize.

[P1][Operability/documentation] configured agent runtime is not an actionable validation contract for the two supported agents, and docs/reference/troubleshooting.mdx:2344-2384 still says the preset allows Node and prescribes Node-only probes. Impact: Hermes users will run a binary this PR correctly denies, misdiagnose healthy fail-closed behavior, and may widen the policy to compensate. Smallest safe fix: provide explicit agent-specific validation commands or named procedures with expected success/failure interpretation, and update troubleshooting to distinguish OpenClaw Node from Hermes Python. Regression: assert the emitted warning selects a concrete supported procedure for each agent and that superseded generic Node guidance is absent for Hermes.

Addressed in commit 2bd37f0. Discord validation metadata now owns separate OpenClaw Node and Hermes venv-Python procedures; policy add selects the procedure from the sandbox agent; CLI/runtime regressions prove each agent receives only its supported command; and troubleshooting now has separate OpenClaw and Hermes sections with success/failure interpretation. The full npm run docs build and npm run validate:pr pass.

Requesting changes at exact head 7bd41ca. Production policy narrowing is correct, but two current-head blockers leave the migration incomplete: (1) the live hermes-discord E2E re-adds Node and performs its REST proof via Node, so it validates a wider authority than production; (2) the manifest and troubleshooting page do not provide an actionable Hermes Python validation procedure and still claim or recommend Node. Please update the live E2E to exercise the Python-only contract and add explicit agent-specific guidance with regression coverage. Verified locally: 184 focused tests passed with 2 skipped, source-shape cases and invalid exceptions are zero, diff hygiene is clean, all commits are Verified, and DCO, required CI, CodeQL, CodeRabbit, and all nine Advisor reviews completed. The arm64 Pi candidate failure is unrelated infrastructure: Perl threads/t/blocks.t segfaulted after 1.39 million upstream tests, so I am rerunning that failed job.

<!-- markdownlint-disable MD041 --> ## Outcome Credential-aware fake messaging APIs remain isolated from outbound network access while a minimal sidecar publishes Docker-assigned ephemeral host ports. Hermes Discord and the shared messaging targets can now reach the fixtures without relying on port publication from an internal-only Docker network. ## Reason The focused Hermes Discord run [33438113538](https://github.com/NVIDIA/NemoClaw/actions/runs/33438113538) successfully built the candidate Hermes Dockerfile and completed onboarding, then failed because the original `-p 0:8080` mapping did not publish a port. Run [33440252925](https://github.com/NVIDIA/NemoClaw/actions/runs/33440252925) exercised the first correction, `127.0.0.1::8080`, on exact candidate `8604af0337c34e1282f3b6c0f5d8245070ec9d55`. Docker retained the requested mapping but again published no port because the credential-aware fake API was attached only to an internal network. Local reproduction confirmed that this network topology, rather than the ephemeral syntax alone, is the root cause. ### Related issues Refs #10655 Relates to #10682 ## Changes - Keep each credential-aware fake API container attached only to its internal Docker network. - Publish REST and Slack websocket ports from a pinned, read-only TCP proxy with all capabilities dropped and no credential environment variables. - Attach the proxy to both the ordinary bridge and the internal fixture network so inbound test traffic reaches the isolated API without granting the API outbound access. - Add focused E2E-support coverage for the Discord and dual-port Slack topology, including regression checks against the old host-port-zero form. ## Verification - `npx vitest run --project e2e-support test/e2e/support/messaging-providers-runtime-proofs.test.ts` — 27 tests passed. - `npm run test:changed` — 33 growth-guard tests and 176 affected tests passed across eight files. - Exact Docker topology smoke — Docker assigned an ephemeral host port, the proxy reached the isolated fake API, the API had only the internal network, and the proxy was read-only with all capabilities dropped and `no-new-privileges` enabled. Temporary containers and the network were removed. - `npm run validate:pr` — pre-commit, commit-message, pre-push, repository, E2E phase-plan, source-shape, growth, secret-scan, and CLI type-check gates passed. - Diff review and secret scan — no secrets, API keys, credentials, or public documentation changes. ## Review notes Both failed focused runs stopped at the fake Discord port lookup after Hermes onboarding passed. Run `33440252925` specifically proves that the first exact-head patch reached `docker run -p 127.0.0.1::8080` and that the internal-only network suppressed the publication. Its cleanup removed the fake container and network, sandbox, and gateway with zero cleanup failures. No credential exposure was observed. The proxy receives only the upstream container name and port numbers through its environment. Expected provider credentials remain confined to the internal-only fake API container. --- Signed-off-by: Prekshi Vyas <prekshiv@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Refactor** * Improved messaging-provider networking with isolated API connections and loopback-only proxy port publishing. * Standardized provider-specific port handling and strengthened validation for unsupported network bindings. * **Tests** * Expanded integration coverage for Discord Gateway and Slack connections. * Verified dynamic port assignment, isolated containers, proxy connectivity, and rejection of externally exposed proxy ports. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Prekshi Vyas <prekshiv@nvidia.com>

Reviewed exact merge head 154699d.\n\nThe production policy narrowing is correct, but the merge from main does not resolve the two existing P1 blockers:\n\n- The Hermes Discord live test still adds Node to its policy and runs the REST proof through Node, so it validates broader authority than the shipped Python-only policy: https://github.com/NVIDIA/NemoClaw/pull/10682#discussion_r3897792689\n- Troubleshooting still tells Hermes users that Discord permits Node and gives Node-based probes, which conflicts with the new policy: https://github.com/NVIDIA/NemoClaw/pull/10682#discussion_r3897819273\n\nSmallest safe fix: make every Hermes live probe execute through the production Python runtime without re-adding Node, and document separate agent-specific probes. Keep regression coverage proving Node remains denied.\n\nExact-head verification passed: CLI and plugin builds, 184 focused tests with 2 skips, diff hygiene, and checked-in bundle digest. DCO, commit signatures, CodeQL, CodeRabbit, and the completed normal gates are green. The PR Review Advisor failed twice before analysis because its runner could not create the nested read-only context mount, so it produced no specialist artifacts; I manually covered all nine security categories. Secrets, input validation, authorization, dependencies, error handling, cryptography/data protection, and configuration are PASS; security testing and holistic least-privilege validation remain FAIL for the live-test mismatch; documentation/operations is WARNING until the probes match the agent policy.

Reviewed exact merge head 86f89a8910a5c9ad18fa551e8d9cf7f373cfe3c1 against base 5fe43c5427da4c79e0f51a72ca999d40e4bfd509. This commit is a sync from main; the current seven-file PR diff is unchanged, so both existing P1 blockers remain:
- The Hermes Discord live lane still restores Node authority and performs its REST proof through Node, allowing the gate to pass without exercising the shipped Python-only policy: #10682 (comment)
- The manifest and troubleshooting guidance still lack an actionable Hermes Python validation procedure and prescribe Node behavior that this policy denies: #10682 (comment)
Smallest safe fix: remove Node from the Hermes live-test policy, execute the credential-bound Discord proof through the reviewed Hermes Python runtime, and provide agent-specific validation procedures. Keep regressions that fail if Node returns, Python cannot reach the bound route, or Hermes documentation recommends the Node probe.
Exact-head validation passed the CLI build; 184 focused tests with 2 skipped; 3 Hermes Discord E2E-support tests; deterministic reviewed-bundle verification; Vitest project membership; and diff hygiene. All seven commits are GitHub Verified, DCO and CodeQL are green, CodeRabbit has no current actionable feedback, and the nine Advisor specialists completed. Documentation and Migration independently confirm the stale-guidance blocker; manual inspection confirms the broader live-test authority that the static specialists missed. Two normal CI jobs are still running.
Security verdict: secrets/credentials PASS; input validation PASS; authentication/authorization PASS for production; dependencies PASS; errors/logging PASS; cryptography/data protection PASS; configuration PASS; security testing FAIL; holistic least privilege FAIL; documentation/operations WARNING.

The original Node-authority, result-classification, and E2E parity blockers are resolved on this head, and authoritative CI is green. Two current-head P1 blockers remain: the REST proof accepts an ambiguous 401 that can occur when credential rewriting fails, and both published Hermes probe surfaces invoke a sandbox-only path as a host command. Exact-head validation passed 45 CLI, 141 integration, and 9 E2E-support tests, the E2E parity guard, and diff hygiene. DCO is green and all 12 PR commits are GitHub Verified. I did not find an exact-head hermes-discord live run; the current oracle would be inconclusive even if it passed.
Security review: secrets/credentials PASS; input validation PASS; authentication/authorization WARNING pending a discriminating REST credential-rewrite proof; dependencies PASS; error handling/logging PASS; cryptography/data protection PASS; configuration security PASS; security testing FAIL because 401 does not prove rewrite; holistic least privilege PASS in the implementation. Accepted product scope is #10655. All nine current-head Advisor specialists completed; the Test Design and Documentation findings below are valid.

[P1] Make this proof distinguish a rewritten credential from the unresolved placeholder. Severity: P1. Impact: this target defaults to a fake Discord token, so a correctly rewritten request returns 401—but an unreplaced openshell:resolve:env:... placeholder also returns 401. Accepting both lets a REST credential-rewrite regression pass the fast test and the live E2E. Smallest safe fix: route the Python request through a controlled fake REST endpoint bound with the production REST credential-rewrite policy, and report success only after that endpoint confirms the stored token was received and the placeholder was not. Regression: retain rejection of missing JSON, errors, timeouts, and unexpected results; additionally reject 401 or any result without verified-token evidence, then run the exact-head live Hermes Discord target.

[P1] Run this probe through the affected Hermes sandbox. Severity: P1. Impact: /opt/hermes/.venv/bin/python and the OpenShell proxy exist inside the sandbox, so copying this host-facing command normally fails before testing Discord egress or tests the wrong network boundary; the CDN snippet and manifest-emitted Hermes guidance have the same problem. Smallest safe fix: explicitly prefix both docs probes and validationWarningLinesByAgent.hermes with nemohermes <name> exec -- (use a -c probe if needed to avoid heredoc forwarding ambiguity). Regression: verify the printed Hermes guidance and docs use the sandbox-qualified form and contain no raw host invocation.

## Outcome Restore the live E2E assertion ratchet after #10682 by keeping one assertion per behavior boundary in the Hermes Discord journey. ## Reason The Hermes Discord security expansion added overlapping checks for the same command outcomes. Current `main` therefore exceeds the no-growth assertion budget even though several checks only restate evidence already enforced by a stronger surviving boundary. ### Related issues Relates to #10682 and #10934. ## Changes - Remove duplicate exit-code, marker, echoed-success, raw-payload, and cleanup assertions whose outcomes are already proved by the surviving boundary check. - Make the native Python gateway proof exit nonzero on import or protocol failure so its single exit assertion represents the full protocol result. - Keep the security outcomes: unauthorized Node gateway and REST access are denied, each authorized Python request begins with the revision-scoped placeholder, the raw token stays absent, authorized gateway and REST traffic succeeds through credential rewrite, bridge residue is absent, and cleanup succeeds. - Require the bridge-residue probe itself to succeed before accepting empty output. - Remove the unused gateway-capture display subprocess; the retained capture assertion reads and validates the same file directly. - Lower the exact live-test budget from 21 to 10 direct expect calls and from 41 to 25 direct assertion points for this journey. - Consolidate the mapped fast proxy contract from three URL-component assertions to one exact-URL assertion. - Keep the image-level model-override case scoped to its JSON rewrite by stubbing the permission helpers that are independently exercised by the following dedicated cases. This repairs the deterministic current-main `normalize_mutable_config_perms: command not found` failure exposed by the managed E2E run. ## Verification - `npm run validate:pr` — passed. - `npm run checks:repository` — passed after final Advisor remediation. - `npm run e2e:assertions:check` — passed with 1,888 direct expect calls. - `npx tsx scripts/checks/e2e-mock-parity.mts --base origin/main --head HEAD` — passed. - `npx vitest run --project integration test/repository/e2e-assertion-census.test.ts` — 13 passed. - Focused E2E support suites for policy binding, proxy request, runtime proofs, and the fake Discord API — 56 passed after final Advisor remediation. - `npm run build:cli && npm run typecheck` — passed. - Focused Oxlint, ShellCheck, shfmt, and diff checks — passed. - Diff inspection — no secrets, API keys, or credentials. ## Review notes The first Advisor pass identified one necessary fail-closed residue check and one unused capture-display command. The current head restores that check, retains explicit placeholder authority for both gateway and REST, and removes the unused command. The managed image E2E on `117679b125` reached 44 passing gateway-isolation cases before failing the pre-existing isolated model-override harness. The current head contains the narrow fixture repair; its exact-head managed rerun is the authoritative confirmation. The live Hermes Discord target was not run locally; CI remains the authoritative managed-environment execution. --- Signed-off-by: Aaron Erickson <aerickson@nvidia.com> <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Tests** - Strengthened end-to-end validation for Discord gateway requests, WebSocket proxy URLs, model overrides, and JSON rewrites. - Improved checks for revision-scoped placeholders, successful command execution, policy-denied requests, and local bridge cleanup. - Updated assertion budgets and per-test allowances to reflect current coverage requirements. - **Chores** - Simplified selected test scenarios while preserving security, isolation, denial, rewrite, and cleanup checks. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Outcome
Hermes Discord egress authorizes only the Hermes/Python runtime binaries it uses. It no longer authorizes a generic Node.js binary. Existing Hermes Discord sandboxes have a named per-sandbox remediation that reapplies the maintained preset and removes the durable old Node grant without changing unrelated policy entries.
Reason
Hermes handles Discord traffic through Python. The previous Node.js entry granted an unused generic runtime access to credential-bound Discord endpoints, and rebuild intentionally preserves the live OpenShell policy, so source-only narrowing did not repair already-deployed sandboxes.

This is a sensitive least-privilege change at the Hermes sandbox-to-Discord boundary. Accepted product scope is recorded in #10655. The remediation reuses the supported policy-apply path so credential bindings and policy entries outside the maintained Discord entry remain intact; a failed apply leaves the live policy unchanged.
