fix(sandbox): give each Hermes sandbox its own OpenAI-compatible API port

[laitingsheng]

Summary

The Hermes OpenAI-compatible API port was a fixed host-wide 8642, so only one Hermes sandbox per host could own its host forward. A snapshot clone therefore received no inference forward, and gateway restart on the clone exited 1 with a forward recovery failure it could never repair. Each Hermes sandbox now allocates its own API port from 8642 through 8652, and every consumer resolves that port instead of the manifest default.

Fixes #8543

Changes

• src/lib/core/ports.ts adds HERMES_API_PORT_RANGE_START/END and isHermesApiPort. 8642 becomes the range start rather than a host-wide reservation.
• src/lib/onboard/hermes-api-port.ts is new: allocation, resolveOnboardHermesApiPort, resolveSandboxHermesApiPort, and retargetHermesApiPortInUrl. The port is published back to NEMOCLAW_HERMES_API_PORT so the sandbox-create environment, the registry row, and the host forward agree on one value without threading an argument through the onboarding entrypoint, matching how ensureAgentDashboardForward already propagates the dashboard port through CHAT_UI_URL. A registered sandbox keeps its recorded port: an explicit environment value is accepted only at the create, recreate, and created-sandbox registration boundaries, and every other consumer rejects a conflicting value before it mutates a host forward. isValidHermesApiPort accepts only the allocation range, so an out-of-range operator value is refused outright.
• src/lib/onboard/dashboard-port.ts extracts findAvailablePortInRange so the dashboard and API allocators share one forward-list, registry, and host-bind view, and adds getRegistryOccupiedHermesApiPorts for the cross-gateway view.
• The registry carries hermesApiPort, sanitised in src/lib/state/registry.ts and validated fail-closed in src/lib/state/gateway-registry.ts so a corrupt value cannot drop occupancy and hand out a colliding port.
• src/lib/actions/sandbox/snapshot.ts allocates the clone's own port before any destructive step, so range exhaustion aborts before deleteSandboxForRestore removes a --force destination, and overrides the value the source-entry spread would otherwise inherit.
• src/lib/actions/sandbox/forward-recovery.ts resolves manifest-declared forward ports against the sandbox's own ports. This fixes both halves of the reported failure: recovery no longer demands the manifest dashboard port from a sandbox that owns a different one, and it targets the sandbox's own API port.
• agents/hermes/start.sh reads NEMOCLAW_HERMES_API_PORT and publishes the resolved value as a 0444 marker at /run/nemoclaw/hermes-api-port, on the root-separated path and on the same-uid path that OpenShell-managed and macOS VM startups take. A one-shot openshell sandbox exec does not inherit the supervisor environment, so agents/hermes/mcp-config-transaction.py, agents/hermes/plugin/__init__.py, and scripts/managed-gateway-control.py read that marker instead. Under privilege separation the marker is root-owned and the sandbox user cannot rewrite it; the transaction helper opens it with O_NOFOLLOW and checks ownership, mode, link count, and size before trusting it. In the same-uid topology the gateway already runs as the sandbox user, so the marker carries that same authority, and a sandbox that cannot publish an allocated port there refuses to start rather than leave its helpers probing a default port any process can bind.
• src/lib/onboard/managed-startup/profile.ts declares the reserved range locally instead of importing core/ports. That module is bundled into the managed image and is also executed directly by node --experimental-strip-types, and neither path resolves a relative value import; src/lib/onboard/managed-startup-profile.test.ts pins the two declarations to the same values.
• tools/mcp-tool-discovery-runtime/reviewed-runtime-bundle/managed-startup-image-runtime.bundle is regenerated for that change, and its pinned digest in test/mcp-tool-discovery-image-contract.test.ts is updated. bundle:reviewed:check reproduced the other three reviewed artefacts byte-for-byte, so only the managed-startup bundle moved.
• src/lib/agent/onboard.ts passes sandboxName through the API-kind dashboard branch, which otherwise announced the manifest default for a Hermes sandbox that owns another port.
• The sandbox agent rejection message, the onboarding ready summary, and scripts/install.sh resolve the sandbox's port instead of naming 8642, and the installer restores a registered Hermes forward rather than the manifest default.
• The reserved-port guards in src/lib/onboard/preflight-ports.ts, src/lib/onboard/hermes-dashboard.ts, and the managed-startup profile validation cover the whole range rather than the single literal.
• ci/source-architecture-budget.json raises four limits. Introducing one module adds edges to snapshot.ts fan-out, the src/lib/onboard root-file count, and core/ports.ts/state/registry.ts fan-in. Two other increases were avoidable and were removed instead: getSandboxHealthProbeUrl moved into forward-recovery.ts, which already owned that dependency, and snapshot.ts no longer imports core/ports.
• The seven Hermes pages now state the condition under which a sandbox receives 8642 instead of calling it the first sandbox's port, document the clone's own API port allocation and the installer's forward-restore failure, and replace the interactive port prompt in the headless procedure with the <api-port> placeholder the credential-rotation page already uses.
• agents/hermes/start.sh restores the runtime directory's owner and mode from root before it refuses startup. Publishing the API port marker replaced an unconditional install -d -m 0755 -o root -g root /run/nemoclaw with an assertion that the directory was already root-owned with mode 0755, and the managed runtime presents that directory before the root-separated gateway starts, so the assertion crash-looped the container during managed activation. Startup still refuses when the restore is not permitted.
• test/e2e/live/managed-image-activation-e2e-helpers.ts adds three fixed startup signals for the Hermes refusals, so an activation failure names which refusal ended the container instead of leaving only a restart count. The container log capture moves from a direct synchronous spawn onto the audited shell probe: test/e2e/fixtures/shell-probe.ts accepts a non-persisting run, which keeps the probe's bounded timeout, kill signal, output limit, and redaction while raw output stays out of the artifact sink.
• docs/reference/troubleshooting.mdx states the range and the occupancy behaviour for a manual NEMOCLAW_HERMES_API_PORT override.
• src/lib/actions/sandbox/gateway-restart.ts is reformatted, and three launch harnesses under test/ extract launch_openclaw_gateway_process. Both arrived from main: the log-tail command landed in a shape the repository formatter rewrites, which failed static-checks, and the launch path now delegates the background process to a helper the harnesses did not assemble, which failed three cli-test-shards jobs. Both reproduce on a pristine origin/main checkout.
• Merged origin/main to keep the branch current. The merges were clean.

Documentation Writer Review

• Documentation writer subagent reviewed the completed changes
• Result: docs-updated
• Evidence: docs/get-started/quickstart-hermes.mdx, docs/reference/commands.mdx, docs/reference/troubleshooting.mdx, docs/deployment/deploy-to-headless-server.mdx, docs/deployment/set-up-mcp-bridge.mdx, docs/security/credential-rotation.mdx, docs/manage-sandboxes/run-sandboxes.mdx, and docs/manage-sandboxes/backup-restore.mdx, plus the changed comments, CLI strings, error strings, and test titles across the diff. The subagent reviewed the writing rules and documentation style over eleven passes, eight of them on the merged tree. The early passes closed six blocking items, including a sandbox agent rejection message and an onboarding ready summary that still emitted the manifest default, docs that pointed operators at status, which prints no port, a guard that applied the Hermes port to any agent, and unit tests that had begun reading the real sandbox registry. A later pass returned docs-missing with 14 findings, among them a Hermes credential-rotation procedure that still hardcoded 8642, an agent-neutral port guard described as Hermes-only, an override whose failure result was unstated, and three reader docstrings that claimed a root-owned marker in a topology where the gateway itself owns it. All were applied. Two further passes corrected an override consequence that had been stated in the wrong direction and a guard that would have rejected the very --recreate-sandbox command its own error recommends; both corrections were traced through src/lib/onboard/dashboard.ts, src/lib/onboard/agent-dashboard-forward.ts, and src/lib/onboard/sandbox-lifecycle.ts before they were accepted. The final pass covers the merged tree at this head and applied nine findings across seven pages: the allocation condition stated as first-sandbox ownership on four pages, the missing clone API-port allocation and its pre-delete abort, the missing range-exhaustion and installer forward-restore entries, an off-vocabulary registry term, a hedged port claim, and the headless procedure's interactive prompt and exit 1, which ends the reader's own SSH session when the typed port is rejected. Every finding was verified against source before it was applied, and two requests to add explanatory comments were declined and recorded for maintainer review.
• Follow-up evidence: Codex Desktop reviewed the readiness fixes after integration with current main, added fail-closed validation for the documented Hermes API port before token retrieval, and confirmed no other documentation changes were needed. The later test-only revision adds non-root marker-owner rejection, dependency stubbing, and fixture cleanup; no user-facing documentation changed. The diagnostic-only revision persists only content-free container state and fixed boolean startup signals when managed onboarding fails. Raw logs remain in memory and never enter the artifact sink; a focused regression proves arbitrary credential-like output is absent from the saved summary. The current head merges origin/main and carries the documentation pass described above. The later commits repair the startup refusal that crash-looped managed activation, name that refusal in the activation diagnostics, and restore two inherited gates; none of them changes a user-facing surface, so no further documentation follows. The final documentation build completed with 0 errors and the 2 previously documented warnings. The internal E2E comment correction accurately describes persisted output as redacted and size-bounded and confirms that disabling persistence writes neither output nor result metadata; no user-facing documentation changed.
• CI-only follow-up: The signed no-file-change revision ac0a20644 and its parent share tree a640293d9e; the documentation writer confirmed docs-no-change because the reviewed user-facing content is identical.
• Agent: Claude Code; Codex Desktop follow-up
• CI staging follow-up: Independent review: PASS — the CI staging comment and assertion identify the exact libssh2 source mismatch; Hermes per-sandbox port documentation and behavior remain unchanged.
• Reservation follow-up: Codex Desktop reviewed the concurrent Hermes API-port reservation change on the current branch revision. The review updated docs/reference/commands.mdx and docs/reference/troubleshooting.mdx to describe pinned-port collision failures. npm run docs completed with 0 errors and the 2 existing hidden-link warnings. No documentation blocker remains.
• Growth-gate follow-up: Codex Desktop reviewed the internal reservation-scope refactor and returned docs-no-change. The refactor preserves port selection, reservation, recreate rebinding, forward handoff, and cleanup behavior. It does not change commands, environment variables, defaults, ranges, errors, or supported workflows. Existing canonical documentation remains current.
• Test-growth follow-up: The concurrency test now uses a deterministic three-call reservation sequence. It preserves the same collision-retry coverage and adds no user-facing change. The current documentation receipt remains docs-no-change. The focused Hermes API-port suite and the repository test-conditional scan pass.
• Installer-test follow-up: Codex Desktop reviewed the test consolidation and returned docs-no-change. The change moves legacy port fallback coverage into the focused Hermes restore suite and lowers the legacy test-size budget. Production code, commands, environment variables, defaults, errors, and recovery workflows do not change. The troubleshooting page already states that legacy records without hermesApiPort use port 8642.
• Clone-fixture follow-up: Codex Desktop reviewed the one-field gateway fixture correction and returned docs-no-change. Production source and documentation are unchanged. The field restores the existing source gateway identity required by the clone assertion and changes no command, default, configuration, output, allocation rule, or recovery workflow. The focused clone and lifecycle-lock tests pass (17 tests).
• API-port forwarding follow-up: Codex Desktop reviewed the fix that resolves the sandbox-owned Hermes API port before the first API-kind host forward and returned docs-no-change. The existing documentation already describes the per-sandbox port contract. The follow-up passed 68 focused CLI tests, CLI type-checking, Biome, and all commit and push hooks.
• Linear-test follow-up: The Hermes environment assertion moved into its own test after the growth gate rejected a conditional inside a test body. This test-only refactor preserves behavior and adds no documentation change. The focused suite now passes 69 tests, and the repository conditional scan passes.
• Main-merge follow-up: Codex Desktop independently reviewed the mechanical current-main integration at c8fbe3ae8619eb69122b7abb4dd239ded242b364 and returned docs-no-change. The sole conflict resolution preserves the Hermes branch architecture allowances and uses the merged tree measured state-root.ts fan-in of 20. No command, configuration, workflow, diagnostic, default, supported behavior, or reviewed Hermes documentation changes. Normal pre-commit and commit-message hooks passed.
• Scoped-creation merge follow-up: Codex Desktop independently reviewed the second mechanical current-main integration at b72939ba94747a8ced4b637daefb81eed8131345 and returned docs-no-change. The sole conflict preserves current main centralized dashboard-port scoped entry points and wraps sandbox creation in the existing Hermes API-port reservation scope. It changes no command, flag, environment variable, port range, default, diagnostic, or operator workflow. Normal pre-commit and commit-message hooks passed.
• Final scoped-creation merge follow-up: Codex Desktop independently reviewed exact commit caba2182b96cfc7ea9599e6c8f2a4ba15170d572 and returned docs-no-change. The final amendment restores only the explicit HermesApiPortReservationScope callback type and formatter indentation. Runtime behavior and the reviewed integration are unchanged. Normal pre-commit and commit-message hooks and the CLI build passed.
• Growth-guard follow-up: Codex Desktop independently reviewed exact commit 4dabe2ecea604ab1029b90c5aa10dbca15aa8057 and returned docs-no-change. Reservation-scope composition moved from src/lib/onboard.ts into the focused Hermes API-port module; scope order, lifetime, arguments, selection, reservation, and cleanup behavior remain unchanged. The entrypoint is net smaller, the focused scope test covers both creation paths, and normal hooks passed.

Verification

• PR description includes a Signed-off-by: line and every commit appears as Verified in GitHub
• Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
• Targeted behavior tests pass for the current change set, or tests are marked not applicable above — command/result or justification: Growth-gate follow-up: 68 focused CLI tests and 18 integration tests passed. npm run typecheck:cli and npm run checks:repository passed. src/lib/onboard.ts is +26/-27 relative to the PR base. the current head adds documentation and one formatter-only source change, so the behaviour suites from the preceding head still apply: npx vitest run --project cli src/lib/onboard/hermes-api-port.test.ts — 22 passed. npx vitest run --project integration test/generate-managed-startup-profile-fixture.test.ts test/mcp-tool-discovery-image-contract.test.ts test/source-architecture.test.ts — 31 passed. npx vitest run --project cli src/lib/onboard/managed-startup-profile.test.ts — 105 passed. On this head: npm run typecheck:cli — exit 0. npm run checks:repository — exit 0. npx biome format over the formatter hook's file set — no drift. npm run docs — 0 errors, 2 warnings. npx vitest run --project integration test/nemoclaw-start-gateway-health.test.ts test/nemoclaw-start-gateway-marker.test.ts test/openclaw-2026-7-startup-compat.test.ts — 51 passed, 1 skipped. npx vitest run --project integration test/hermes-api-port-startup.test.ts test/hermes-api-port-marker.test.ts — 10 passed. npx vitest run --project e2e-support — 2481 passed, 10 skipped. CI on the preceding head reported all eight cli-test-shards green and all three PR build and direct managed startup jobs passing, and the PR Review Advisor reported 0 blockers. The later internal-comment correction was validated with 52 focused E2E-support tests and all applicable repository hooks.
• Applicable broad gate passed — npm test for broad runtime/test-harness changes; npm run check for repo-wide validation/coverage changes — command/result: not run locally; left to CI. For the latest test consolidation, the focused installer restore suite passed. The test-size, title, project-membership, source-shape, and conditional scans passed. Pre-commit and pre-push hooks passed. GitHub reports the current commit as Verified.
• Quality Gates section completed with required justifications or waivers
• No secrets, API keys, or credentials committed
• npm run docs builds without warnings (doc changes only) — npm run docs exits 0 with 0 errors and 2 warnings. Both warnings are pre-existing learn.microsoft.com language-reference links in docs/reference/troubleshooting.mdx that this change does not touch, so the box stays clear rather than claiming a warning-free build.
• Doc pages follow the style guide (doc changes only)

📝 Walkthrough

Walkthrough

Hermes now supports per-sandbox API ports in the 8642–8652 range. The selected port is allocated, persisted, forwarded, published through protected runtime markers, resolved by runtime checks, and used by recovery, cloning, installer restoration, and documentation.

Changes

Hermes API port allocation

Layer / File(s)	Summary
Port contracts and allocation src/lib/core/ports.ts, src/lib/onboard/hermes-api-port.ts, src/lib/onboard/dashboard-port.ts, src/lib/state/*, src/lib/onboard/sandbox-*	Added Hermes API port validation, occupancy tracking, allocation, reservation scopes, registry persistence, and startup environment wiring.
Runtime publication and resolution agents/hermes/*, scripts/managed-gateway-control.py	Hermes startup publishes a protected API-port marker. Runtime probes and readiness checks resolve the configured port before use.
Sandbox forwarding and lifecycle src/lib/onboard/*, src/lib/actions/sandbox/*, scripts/install.sh	Forwarding, dashboard rendering, recovery, snapshot cloning, and installer restoration use each sandbox’s API port.
Validation, diagnostics, and guidance test/*, docs/*, ci/*, vitest.config.ts	Added port, marker, recovery, diagnostic, and integration coverage. Updated operator guidance, test membership, hashes, and budget thresholds.

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

Mergeability Score: 🔵 Low · up to 4dabe

The PR changes Hermes sandbox API-port allocation and recovery behavior, while one workflow comment still appears to describe the staging sources in reverse. That documentation issue could mislead maintainers but has no indicated runtime impact; the PR is mergeable with owner follow-up to correct it.

318-344: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Reject explicit Hermes API/dashboard port overlaps before sandbox creation.

assertDashboardPortNotReserved rejects dashboard ports in 8642–8652, but resolveOnboardHermesApiPort accepts any valid NEMOCLAW_HERMES_API_PORT without checking the resolved dashboard port. Thus NEMOCLAW_HERMES_API_PORT=18789 can map both resources to one host port. Reject this equality and add regression tests for both cases.

• GPT-5.6 Terra (primary): Failed after a partial review · low confidence · 0 blockers · 0 warnings · 0 suggestions
• Nemotron 3 Ultra (second opinion): Failed after a partial review · low confidence · 0 blockers · 1 warning · 3 suggestions

Second-opinion terminology and E2E selections are advisory. Live E2E does not run automatically for pull requests.

2 semantic terminology decisions

Terminology decisions are advisory. They affect the assessment only when a separate finding identifies concrete semantic impact.

• justified — per-sandbox API port at src/lib/actions/sandbox/snapshot.ts:290: Keep the term. The modifier identifies the allocation and forwarding boundary.
• established — root-separated topology at agents/hermes/plugin/init.py:1047: Keep the established term.

E2E guidance

Advisory only. A maintainer can dispatch the default E2E suite for the commit under review.

Recommended E2E: managed-image-protected-runtime

Manual-only E2E: cloud-onboard, hermes-e2e, hermes-inference-switch, managed-image-multiarch-startup, security-posture, bedrock-runtime-compatible-anthropic, channels-stop-start, device-auth-health, hermes-shields-config, onboard-repair, onboard-resume, openclaw-inference-switch, cloud-inference, full-e2e, dashboard-remote-bind, issue-4462-scope-upgrade-approval, rebuild-openclaw, state-backup-restore
The manual PR workflow does not run these selectors for the commit under review. Run them from reviewed code on main.

[cv]

agents/hermes/start.sh:3319 publishes the trusted Hermes API-port marker only on the root startup path. The supported managed non-root path exits through lines 3254-3284 without creating it. agents/hermes/mcp-config-transaction.py, agents/hermes/plugin/__init__.py, and scripts/managed-gateway-control.py then silently use port 8642. For a sandbox configured for port 8643, a sandbox user can bind 8642 and cause reload or lifecycle probes to accept the wrong listener. Publish a supervisor-owned, sandbox-user-unwritable binding before non-root helpers can run, or make those helpers fail closed when the binding is absent. Add an integration regression test that starts managed non-root Hermes on 8643, verifies the binding ownership and mode, verifies all helpers probe 8643, and proves a listener on 8642 cannot satisfy readiness.

invalid registry state.

In `@agents/hermes/start.sh`:
- Around line 2915-2929: Update both current-user and root API-port marker
publication paths, including publish_hermes_api_port_marker_current_user and the
corresponding root flow, to write the value to a temporary file, apply final
permissions (and root ownership where applicable), then atomically rename it
into place. Remove the successful default-port fallback when cleanup or
replacement fails: if an old marker remains or publication cannot complete, fail
closed with a nonzero result. Add restart coverage for stale markers and
publication failures.
- Around line 3342-3344: Harden the marker publication around
HERMES_API_PORT_MARKER by validating that its parent directory is a real
root-owned, non-writable directory before writing. Replace the direct printf
redirection with a root-created temporary file in that directory, set its
contents and permissions, then atomically rename it to the marker so planted
symlinks cannot be followed; add a negative test covering a pre-existing marker
symlink.

In `@docs/security/credential-rotation.mdx`:
- Around line 219-221: Update the credential-rotation commands to use the
placeholder <api-port> instead of the literal 8642, including forwarding and API

shown for their selected <sandbox> by openshell forward list, while preserving
the existing first-sandbox context.

iterate through every port from HERMES_API_PORT_RANGE_START through

Preserve or add adjacent-port assertions to confirm ports immediately outside
the declared range remain accepted.

In `@test/hermes-api-port-marker.test.ts`:
- Around line 15-33: Remove both conditionals from
runHermesApiPortMarkerPublication by extracting the runtime-parent and
stale-marker setup variants into named helpers, such as writable, blocked, and
read-only-stale-marker setups. Update the runner to accept and invoke the
selected setup helper so its body remains linear while preserving the existing
test scenarios.

Final readiness classification for the current revision:

• All review threads are resolved. CodeRabbit confirmed that the asynchronous-caller concern does not apply to the production call chain.
• All 12 CLI shards, the aggregate suite, type checks, static checks, installer integration, documentation review, DCO, commit lint, growth guardrails, CodeQL, and the security scans pass.
• Hermes, Deep Agents Code, OpenClaw, and staging QA fail at the same completed-image security package inventory assertion. This PR does not change managed-image construction or package inventory inputs, so these are shared CI or base-image drift rather than PR-related regressions.
• Both advisor engines failed within their analysis protocol on the permitted retry. The trusted publisher completed and reports no required advisor follow-up.

The single safe retry is exhausted, so I am not rerunning these deterministic or advisor-infrastructure failures. The PR is technically remediated but still awaits successful external repository gates and independent human review. Large change flag: 66 files, +2,974/-263.
