Summary

The Pi agent directory held only its manifest, so no image source, entry point, configuration generator, or baseline policy existed, and the candidate managed-image agent list had no consumer. This adds the NemoClaw-owned Pi image sources that install one exact package version and integrity value with lifecycle scripts disabled, the startup entry point, the credential-free model catalog generator, the deny-by-default baseline policy, and the supply-chain record. CI now builds, validates, and publishes exact Pi candidate digests for linux/amd64 and linux/arm64 under a contract artifact name outside the all-agent cohort download pattern, so a published candidate cannot enter the atomic release cohort.

Resolves #7925

Changes

  • Add agents/pi/Dockerfile.base and agents/pi/Dockerfile: the reviewed Debian security package set, the sandbox user at uid/gid 999 declared by MANAGED_IMAGE_RUNTIME_IDENTITIES, the resource-limit hooks, the freestanding managed-bootstrap entry point, and the root-owned managed-startup handoff.
  • Pin the Pi runtime through agents/pi/pi-runtime/package.json and package-lock.json, installed with npm ci --omit=dev --ignore-scripts. The build asserts the version against package.json and the integrity value against the lockfile before installing.
  • Add agents/pi/start.sh: umask 077, entrypoint environment normalization, the root-to-sandbox setpriv drop, fail-closed resource limits, proxy values read only from root-owned image files, and PI_OFFLINE=1 with PI_TELEMETRY=0.
  • Add agents/pi/generate-config.ts, which writes models.json at mode 0600 with no credential and rejects an inference API family other than openai-completions or a base URL that carries credentials.
  • Add agents/pi/policy-additions.yaml, which allows the managed inference route only and lists no agent-writable binary path.
  • Add agents/pi/dependency-review.md with the package identity, lockfile digest, and audit result.
  • Add the read-only pi-candidate pull-request job and package-writing pi-candidate-publish job to .github/workflows/managed-images.yaml and the Pi lanes to .github/workflows/base-image.yaml, both covering linux/amd64 and linux/arm64.
  • Add scripts/checks/pi-candidate-artifacts.mts to npm run checks:repository. It binds the manifest, lockfile, both image sources, the dependency review, and the managed-image contract to one package identity, and verifies that the candidate contract artifact name stays outside the all-agent cohort download pattern. This is the current consumer of CANDIDATE_MANAGED_IMAGE_AGENTS, which had none.
  • Add tools/managed-images/validate-candidate-contract.mts, which reuses parseManagedImageContractV1 so a candidate digest is held to the same exact identity rules as a shipped image, and rejects a contract whose agent is not a candidate.
  • Add agents/pi/Dockerfile and agents/pi/Dockerfile.base to the production build-arg guard so the new PI_NPM_INTEGRITY pin cannot be overridden from a build command.
  • Add test/pi-candidate-runtime-artifacts.test.ts, plus its watch triggers and its nine source-shape contract exceptions.
  • Repair the Pi local-base handoff by exporting Docker and OCI archives from one Docker-container Buildx solve. Candidate validation loads the Docker archive, while both candidate builds and digest-only publication use the digest-qualified OCI layout as a named build context.
  • Fix agents/pi/generate-config.ts to set the provider api field Pi's own model-composition code requires and a non-secret managed-route apiKey placeholder matching Deep Agents Code's identical pattern; without the api field Pi could not compose any model. Reject an inference setting that is empty after trimming.
  • Remove a Darwin-compat chmod in agents/pi/Dockerfile that widened /sandbox/.bashrc and /sandbox/.profile away from the exact mode start.sh's integrity check requires, which failed every Darwin-compat Pi start closed. Compare the installed Pi version by exact match instead of substring in both Dockerfiles.
  • Port Hermes's corporate-CA merge into agents/pi/start.sh so a CA baked at build time reaches Node's runtime trust bundle, matching the existing Hermes and shared scripts/nemoclaw-start.sh behavior.
  • Invoke tools/managed-images/validate-candidate-contract.mts through node --experimental-strip-types instead of npx tsx in the shared Pi candidate steps, which never run npm ci. The pull-request job has read-only permissions. The non-pull-request publication job holds packages: write.
  • Close a file-system race CodeQL flagged in test/pi-candidate-runtime-artifacts.test.ts and tighten its network-policy binary-path assertion to an exact allowlist.
  • Add the missing Pi entries to test/runtime-provider-source-shape.test.ts and the missing workflow watch triggers in test/helpers/vitest-watch-triggers.ts.
  • Run the same declared-entrypoint qualification in the read-only pull-request Pi matrix against the locally built image, while trusted publication continues to qualify the exact published digest. Both paths verify the sandbox UID, resource limits, corporate-CA membership and root-owned bundle, persisted trust variables, and independent-shell handoff.

Quality Gates

  • Tests added or updated for changed behavior
  • Existing tests cover changed behavior — justification:
  • Tests not applicable — justification:
  • Docs updated for user-facing behavior changes
  • Docs not applicable — justification: Public docs remain deferred because Pi stays out of SHIPPED_MANAGED_IMAGE_AGENTS. The internal supply-chain record in agents/pi/dependency-review.md is updated; [Pi 7/8] Document Pi onboarding, operations, and release support #7929 owns public Pi documentation and [Pi 8/8] Activate Pi in supported inventory and release cohort #8818 owns activation.
  • Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
  • Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: pending maintainer review of the Pi baseline policy, the startup privilege drop, the pinned install, and the corporate-CA merge.
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes
  • Result: docs-updated
  • Evidence: agents/pi/dependency-review.md — independently reviewed the complete 20-file diff at 5336c9348c0b8ec278a31c5340aa62840ec34b77 against base b89a870c70091c4ca97c692fd196327aead776a7. All 15 non-merge PR commits and all 20 PR-specific file blobs are unchanged from the prior reviewed head. The merge adds six PR chore(openshell): trust v0.0.103 release identities #8908 OpenShell trust-validation files outside the Pi image, runtime, manifest, policy, package data, and candidate workflows. The dependency record still matches Pi 0.84.1, its exact npm integrity, the lockfile SHA-256, SHA-512 values for all 144 resolved archives, and the zero-vulnerability audit. Pi remains non-selectable and outside the shipped and atomic release cohorts. Issue [Pi 7/8] Document Pi onboarding, operations, and release support #7929 owns public documentation, and [Pi 8/8] Activate Pi in supported inventory and release cohort #8818 owns activation. At the exact reviewed head, 132 focused tests passed across four files; npm run checks:repository, npm run docs, and git diff --check also passed.

… lane

The Pi agent directory held only its manifest, so no image source, entry
point, configuration generator, or baseline policy existed and the candidate
managed-image agent list had no consumer. This adds the owned image sources
that install one exact package version and integrity value with lifecycle
scripts disabled, the startup entry point, the credential-free model catalog
generator, the deny-by-default baseline policy, and the supply-chain record.

CI publishes exact Pi candidate digests for linux/amd64 and linux/arm64 under
a contract artifact name outside the all-agent cohort download pattern, so a
published candidate cannot enter the atomic release cohort. A repository check
binds the manifest, lockfile, both image sources, the dependency review, and
the managed-image contract to the same package identity. Pi remains
non-selectable in onboarding.

📝 Walkthrough

Walkthrough

This PR adds the Pi runtime, hardened base and managed images, multi-platform candidate publication, candidate contract validation, and runtime artifact tests. Pi remains outside the shipped all-agent cohort.

Changes

Pi runtime delivery

Layer / File(s) Summary
Pinned Pi base image
agents/pi/Dockerfile.base, agents/pi/pi-runtime/package.json, agents/pi/dependency-review.md
Adds pinned Pi dependencies, security packages, npm remediation, sandbox identity, runtime defaults, and dependency verification records.
Pi runtime image and startup
agents/pi/Dockerfile, agents/pi/generate-config.ts, agents/pi/policy-additions.yaml, agents/pi/start.sh, agents/pi/manifest.yaml
Builds the managed runtime image, generates a credential-free model catalog, applies filesystem and network policy, validates runtime inputs, and starts Pi with restricted permissions and resource limits.
Candidate contract validation
scripts/checks/pi-candidate-artifacts.mts, tools/managed-images/validate-candidate-contract.mts, scripts/checks/run.mts, scripts/check-production-build-args.sh, ci/source-shape-test-budget.json
Validates pinned artifacts, candidate registration, platform contracts, image destinations, and separation from the all-agent release cohort.
Multi-platform publication and validation
.github/workflows/base-image.yaml, .github/workflows/managed-images.yaml, test/pi-candidate-runtime-artifacts.test.ts, test/helpers/vitest-watch-triggers.ts, test/runtime-provider-source-shape.test.ts, test/vitest-watch-triggers.test.ts
Builds Pi images for AMD64 and ARM64, publishes immutable digests and a validated manifest, uploads separate candidate contracts, and tests runtime artifact boundaries.

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

Merge Risk: 🟡 Moderate · up to d5b02

This PR adds and publishes pinned Pi runtime images with new startup, policy, credential, and certificate-handling behavior. Merge should wait for the required maintainer review of these sensitive changes, and the Podman contract test needs explicit owner follow-up because it does not yet verify observable composition behavior.

  • justified — candidate managed image at scripts/checks/pi-candidate-artifacts.mts:7: Keep `candidate managed image` where the exclusion from the shipped cohort matters.
  • established — candidate contract at tools/managed-images/validate-candidate-contract.mts:10: Keep `candidate contract` for non-shipped managed-image publication evidence.

E2E guidance

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

Warnings

Warnings do not block.

PRA-1 Warning — Do not continue after a sandbox resource-limit failure

  • Location: agents/pi/Dockerfile.base:318
  • Category: security
  • Problem: The login and interactive Bash hooks continue after `harden_resource_limits` or `verify_resource_limits_exact` fails.
  • Impact: A fresh OpenShell exec or connect shell can run without the required nproc and nofile limits, unlike the managed entrypoint process.
  • Recommendation: Make the shell hook reject the shell when the resource-limit helper is absent or either limit operation fails, or enforce the limits at the authoritative OpenShell shell-creation boundary.
  • Verification: Inspect the profile and Bash startup hook after the change, then use the existing shell-boundary test evidence to confirm a failing helper produces a nonzero shell startup result.
  • Test coverage: Add a regression test that starts fresh login and interactive shells with a failing limit helper and verifies that each shell is rejected rather than continuing.
  • Evidence: agents/pi/Dockerfile.base:318-326 writes both shell hooks with `|| { ...; true; }`. agents/pi/Dockerfile.base:302-313 states that OpenShell exec and connect shells do not inherit entrypoint limits.

Do not require workflow matrix ordering.

Matrix entry order does not change the supported platform set. Sort the collected platforms before each assertion so a harmless reorder does not fail the test.

Inline comments:
In @.github/workflows/managed-images.yaml:
- Around line 1048-1050: Update the workflow step containing the managed-image
contract validation command to install dependencies with npm ci
--ignore-scripts, then invoke the lockfile-installed binary at
node_modules/.bin/tsx directly instead of using npx tsx. Preserve the existing
validate-candidate-contract.mts arguments and platform behavior.
- Around line 986-1009: Update the Pi candidate publication flow around the
publish step so the digest written to the managed-image contract comes from the
artifact that passed the complete runtime validation. Reuse the validated build
for publication, or run all existing runtime checks against the published
${REPOSITORY}@${DIGEST} before recording it; do not publish an independently
rebuilt image without validation.

In `@agents/pi/Dockerfile`:
- Around line 236-245: Remove the chmod command that adds write permissions to
/sandbox/.bashrc and /sandbox/.profile in the NEMOCLAW_DARWIN_VM_COMPAT block,
preserving their required root:root:444 metadata for the start.sh security
checks.

In `@agents/pi/Dockerfile.base`:
- Around line 350-359: Update agents/pi/Dockerfile.base lines 350-359 to compare
the trimmed output of /usr/local/bin/pi --version exactly with PI_VERSION,
rather than using substring matching; update the corresponding pi --version
check in agents/pi/Dockerfile lines 141-151 the same way. In
agents/pi/Dockerfile lines 141-151, remove the duplicated PI_VERSION default so
both checks use the intended pinned value.

Apply the same fix in `@agents/pi/Dockerfile` around lines 141 - 151: The runtime
Dockerfile contains the duplicated default and the same substring version
assertion.

In `@agents/pi/generate-config.ts`:
- Around line 32-43: Update normalizeMetadata to trim the input and reject the
trimmed result when it is empty, while preserving the existing control-character
validation. Ensure readRequiredEnv values passed through normalizeMetadata
cannot produce empty defaultModel or model id metadata.
- Around line 14-16: The managed provider configuration should set api to
settings.inferenceApi so Pi can compose the configured model, and remove or
avoid relying on the unsupported provider type field. Configure the provider’s
apiKey using the managed credential’s environment-variable reference when
available; otherwise preserve the supported authentication flow through login,
auth.json, or the CLI API-key option so the model is available for selection.

In `@agents/pi/start.sh`:
- Around line 184-192: Update agents/pi/start.sh before prepare_runtime_env to
merge the corporate CA with the OpenShell bundle when present, then export the
resulting path through SSL_CERT_FILE and NODE_EXTRA_CA_CERTS. Use the existing
Hermes CA-merge behavior as the reference and preserve both trust anchors for
Node.

In `@test/helpers/vitest-watch-triggers.ts`:
- Around line 63-67: Update the watch mapping associated with
runTests("test/pi-candidate-runtime-artifacts.test.ts") to also match
.github/workflows/managed-images.yaml and .github/workflows/base-image.yaml,
while preserving the existing agent artifact patterns and test assignment.

In `@test/pi-candidate-runtime-artifacts.test.ts`:
- Around line 201-203: Update the binary path assertions in the runtime
artifacts test to require each path to belong to the explicit approved
image-owned proxy path set rather than merely not starting with "/sandbox". Add
a negative assertion covering an agent-writable path such as "/tmp/agent-proxy",
while preserving the existing binaries iteration.

Reviewed exact head 5f088d4.

Blocking findings:

  1. agents/pi/manifest.yaml does not declare the accepted linux/amd64 and linux/arm64 architecture set or the startup-profile contract. Issue #7925 explicitly requires both in the manifest, not only in workflow matrices and OCI labels, and also requires repository checks to validate that manifest contract. Add the fields using the repository schema and negative tests that reject omission or drift. This is an accepted product-scope contract, not advisory metadata.

  2. merge_corporate_proxy_ca exports SSL_CERT_FILE, CURL_CA_BUNDLE, REQUESTS_CA_BUNDLE, GIT_SSL_CAINFO, and NODE_EXTRA_CA_CERTS, but prepare_runtime_env writes only SSL_CERT_FILE and NODE_EXTRA_CA_CERTS to /tmp/nemoclaw-proxy-env.sh. Independent exec/login shells therefore lose the explicit Requests, curl, and Git trust settings that this Pi port claims to support. Persist all five variables and test the shell handoff. This confirms the two still-open CodeRabbit findings on agents/pi/start.sh.

  3. Both local and published candidate checks invoke /usr/local/bin/pi and /bin/bash with --entrypoint, so they bypass /usr/local/bin/nemoclaw-start. The new root-to-sandbox handoff, exact resource-limit enforcement, trusted proxy reconstruction, CA merge, and default hold behavior can all be broken while the workflow records a candidate contract. Exercise the published digest through its declared entrypoint without an override and assert the effective user, limits, proxy/trust environment, and long-running default behavior before recording the contract.

The accepted product decision in #7926 establishes Pi scope, and the candidate/cohort separation is otherwise well designed. Earlier automated findings about validating the separately published digest, avoiding unpinned npx, exact version comparison, config API shape, Darwin modes, and workflow triggers are resolved in this head.

Security review:

  • Input validation: PASS — model, API family, URL credentials/query/fragment, proxy host, and proxy port are validated.
  • Authentication and authorization: PASS — the generated model catalog contains only a non-secret managed-route placeholder; upstream credentials remain outside the image.
  • Secrets and sensitive data: PASS — image, config, state, and workflow checks reject provider credential material.
  • Injection risks: PASS — pinned npm installation disables lifecycle scripts and runtime metadata is normalized before serialization.
  • Data exposure and privacy: PASS — Pi state is owner-only and the policy exposes only managed inference routes.
  • Cryptography: WARNING — CA source validation is careful, but three client-specific trust variables are lost across the exec-shell handoff.
  • Dependencies and supply chain: PASS — package version and SRI, lock closure, base images, actions, package fixes, and candidate digests are pinned and checked.
  • System security: FAIL — the accepted manifest contract is incomplete and candidate qualification bypasses the entrypoint security boundary.
  • Testing and verification: FAIL — required negative manifest checks and declared-entrypoint runtime proof are absent; broad CI does not exercise those paths.

Files reviewed: both managed-image workflows; all agents/pi/ runtime, image, config, policy, manifest, lock, and dependency-review artifacts; candidate contract/check tools; source-shape and watch-trigger budgets/tests; production build-argument guard.

Declare the accepted architecture set and startup-profile contract version
in the Pi manifest, validated against the managed-image contract with
negative tests for omission and drift.

Forward every merged corporate CA variable through the Pi runtime
environment handoff, and propagate a failed Pi version check through the
tr pipe in both Dockerfiles.

Exercise the published Pi candidate digest through its declared entrypoint
before recording its contract, proving PID 1 drops to the sandbox user,
hardens its resource limits, and persists the trusted proxy environment.

Reviewed current head 887be5fc75359272f9cc02fb23f492b0c9c16950 after the follow-up.

The manifest architecture/startup fields and all five CA variables are now present. Two blockers remain:

  1. .github/workflows/managed-images.yaml says the published digest is exercised “through its declared entrypoint” and “with no command,” but the command still passes --entrypoint /usr/local/bin/nemoclaw-start. This bypasses the image's declared ENTRYPOINT metadata. A candidate whose Dockerfile entrypoint is missing or changed can still record a passing contract. Run the digest without --entrypoint and without a command, then retain the existing UID, limit, environment, and held-state assertions.

  2. test/pi-candidate-runtime-artifacts.test.ts only checks that the five CA variable names occur in prepare_runtime_env; it does not exercise the shell handoff. The published-digest runtime check verifies only the default proxy exports and supplies no corporate CA. Add a behavior assertion that invokes the entrypoint with a valid injected CA and confirms SSL_CERT_FILE, CURL_CA_BUNDLE, REQUESTS_CA_BUNDLE, GIT_SSL_CAINFO, and NODE_EXTRA_CA_CERTS are present with the expected merged path in /tmp/nemoclaw-proxy-env.sh and in an independent shell that sources it.

Security review at this head:

  • Input validation: PASS.
  • Authentication and authorization: PASS; provider credentials remain outside the image.
  • Secrets and sensitive data: PASS; image/state scans remain fail-closed.
  • Injection risks: PASS; package installation and serialization stay pinned and bounded.
  • Data exposure and privacy: PASS.
  • Cryptography and trust stores: BLOCKED on behavior proof of the CA handoff.
  • Dependencies and supply chain: PASS; package, integrity, image, action, and digest pins remain checked.
  • System security: BLOCKED because candidate qualification still overrides the declared entrypoint boundary.
  • Testing and verification: BLOCKED by the two missing runtime assertions above.

The accepted Pi scope in #7926 otherwise establishes product scope for this change.

Reviewed exact head 5d5ef4a2750e100558bc75af5ffe98a0d833e489.

The declared-entrypoint launch and the five-variable shell handoff now cover the two previous findings. Two blockers remain:

  1. The qualification mounts a generated corporate CA but only checks that the five variables point at /tmp/nemoclaw-ca-bundle.pem. It never proves that the mounted CA was appended to that bundle, so the test still passes if the entrypoint silently leaves OpenShell/system trust unchanged. Compare the generated certificate (for example by fingerprint or normalized PEM content) with the merged bundle and fail unless the injected CA is present.

  2. The current head is behind main and its required static-checks and CLI shard fail the onboarding decision-ratchet (handleRemoteProviderSelection: actual 76, recorded 80). Update from current main so the branch carries the ratcheted budget and rerun the required checks.

Reviewed exact head bbf27dc472897e989d8168e7655563688241e71e.

The declared-entrypoint candidate run now compares the mounted corporate CA with the merged bundle by X.509 fingerprint, which resolves the remaining trust-store proof. The Pi scope remains established by accepted issue #7926, and the exact-head candidate, sandbox, CLI, security, and package checks are green so far.

One blocker remains: this head contains deee72ea6d459a8a356422912df048d9aeb73f25 but not current base d4ed93ab3d1edda4f5a4ff494b305c63e419cdfb. Reconcile current main, preserving the Pi entrypoint and CA fixes and the current Podman portable-lifecycle behavior, then rerun required CI and request an exact-head review. The Nemotron review advisor and OpenClaw direct-startup job are also still running.

Security review at this head:

  • Input validation: PASS.
  • Authentication and authorization: PASS; provider credentials remain outside the image.
  • Secrets and sensitive data: PASS; image and state checks remain fail-closed.
  • Injection risks: PASS; installation and generated configuration remain pinned and bounded.
  • Data exposure and privacy: PASS.
  • Cryptography and trust stores: PASS; the published candidate now proves the injected CA is present in the merged bundle and that all five client trust variables survive the shell handoff.
  • Dependencies and supply chain: PASS; package, integrity, base-image, action, digest, and publication contracts remain pinned and checked.
  • System security: PASS; qualification uses the declared entrypoint without a command and verifies the non-root user, limits, trust environment, and held state.
  • Testing and verification: BLOCKED only on reconciliation with current main and completion of the remaining required jobs.

Reviewed exact head 81ced5e18c2c6eb385ce5007cd32975d926e41b4 against current base d4ed93ab3d1edda4f5a4ff494b305c63e419cdfb.

The current head resolves the prior base, trust-store, and package-integrity findings. In particular, the root-to-sandbox CA handoff is root-owned and read-only, all five client trust variables are verified after the privilege drop, and the six supplemented @earendil-works SHA-512 integrities match the registry metadata and tarball bytes. The accepted Pi candidate scope remains bounded by #7925/#7926; this does not mark Pi as shipped or make the deferred public documentation canonical.

One exact-head blocker remains. The pull-request pi-candidate job builds the local amd64/arm64 candidate and inspects it only through --entrypoint overrides. The actual /usr/local/bin/nemoclaw-start exercise at .github/workflows/managed-images.yaml:1090 is guarded by github.event_name != 'pull_request' and runs only against a later published digest. Because this PR changes the entrypoint's privilege drop, resource limits, and corporate-CA handoff, its PR lane must exercise each locally built candidate through the declared entrypoint and verify those three boundaries without publication or package-write permission. Add a workflow contract test that prevents that PR qualification from being guarded away.

The unrelated portable-resume-lock-boundary shard timeout is being rerun on this same SHA; it should be green before the next review.

Security review at this head:

  • Input validation: PASS.
  • Authentication and authorization: PASS; provider credentials remain outside the image.
  • Secrets and sensitive data: PASS; image and state checks remain fail-closed.
  • Injection risks: PASS; installation and generated configuration remain pinned and bounded.
  • Data exposure and privacy: PASS.
  • Cryptography and trust stores: PASS at the implementation level; the merged bundle and five trust variables are validated across the root/non-root handoff.
  • Dependencies and supply chain: PASS; package, integrity, base-image, action, digest, and candidate-cohort contracts remain pinned and checked.
  • System security: PASS at the implementation level; the non-root boundary and immutable CA bundle are enforced.
  • Testing and verification: BLOCKED because the pull-request candidate lane bypasses the exact entrypoint boundary changed here.

Security review: PASS

Reviewed PR #9100 at exact latest PR commit d8fbd4d772058a96edb34eca59f9b64acf390095 against base d4ed93ab3d1edda4f5a4ff494b305c63e419cdfb.

No blocking security finding remains in the complete 22-file effective diff.

  • Input validation: PASS. The generator rejects control characters, empty metadata, unsupported API families, and inference URLs with credentials, query strings, or fragments. Proxy host and port values are validated before use.
  • Authentication and authorization: PASS. The generated Pi catalog carries only the non-secret managed-route placeholder. The upstream provider credential remains outside the image and sandbox. Pull-request candidate jobs have contents: read; only trusted non-pull-request publication jobs retain packages: write.
  • Secrets and sensitive data: PASS. Image and state checks reject provider credential material. The candidate workflow does not persist secrets in image, contract, or evidence artifacts.
  • Injection risks: PASS. Package lifecycle scripts are disabled. Configuration is serialized as JSON. Proxy values are read from root-owned image files, validated, and shell-quoted before the sandbox-user environment handoff.
  • Data exposure and privacy: PASS. Pi state is owner-only. The baseline policy exposes only the managed inference route and provides no agent-writable executable path.
  • Cryptography and trust stores: PASS. The corporate CA source must be a no-follow regular CA certificate. The root phase builds a root-owned read-only merged bundle, and qualification proves certificate membership by fingerprint plus all five client trust variables after the privilege drop.
  • Dependencies and supply chain: PASS. Pi 0.84.1, its npm integrity, the complete 144-archive lock closure, base images, GitHub Actions, security packages, candidate image digests, and contract identity are pinned and checked. Installation uses npm ci --omit=dev --ignore-scripts.
  • System security: PASS. The declared entrypoint starts as root only for guarded setup, then uses setpriv to run as uid/gid 999 with exact process and file limits. The image policy is deny-by-default. Pi remains excluded from listAgents, loadAgent("pi"), the shipped image set, and the all-agent publication cohort.
  • Testing and verification: PASS for the reviewed change. The current pull-request lane exercises each local architecture candidate through the declared entrypoint with no command, then verifies the sandbox uid, limits, protected trust bundle, proxy and CA handoff, and held state. The final d8fbd4d7 change fixes the prior raw NO_PROXY text comparison by sourcing the persisted environment in an independent sandbox-user shell and comparing all upper- and lowercase proxy variables by value. Exact local validation passed the Pi contract 27/27, repository checks, Oxfmt, and git diff --check. Protected amd64 and arm64 candidate jobs are still running, so this review does not authorize merge.

The two current CodeQL review threads at test/pi-candidate-runtime-artifacts.test.ts:271 are duplicate false positives. The reported ${REPOSITORY}@${DIGEST} text is a single-quoted test fixture used to assert the workflow's shell source. JavaScript performs no template interpolation or evaluation of that string.

Accepted scope is established by #7925 and the accepted #7926 Pi 0.84.1 decision. This PR keeps public activation deferred to the remaining Pi issues.

No blocking security finding remains. The sole delta from the complete nine-category security PASS at d8fbd4d772058a96edb34eca59f9b64acf390095 changes one test assertion. It builds the literal workflow fixture reference="${REPOSITORY}@${DIGEST}" by string concatenation, then performs the same toContain check. It does not evaluate the string or change workflow, image, runtime, credential, permission, trust-store, package, or release-cohort behavior.

  • Input validation: PASS. Production validation is byte-identical to the prior review.
  • Authentication and authorization: PASS. Pull-request candidate jobs retain contents: read; trusted publication jobs retain their existing package permission.
  • Secrets and sensitive data: PASS. No secret, environment value, artifact content, or credential boundary changes.
  • Injection risks: PASS. The new JavaScript expression constructs a fixed test string and never evaluates it. The reported template text is not an interpolation sink.
  • Data exposure and privacy: PASS. Pi state and image boundaries are unchanged.
  • Cryptography and trust stores: PASS. Certificate fingerprint and merged trust-bundle checks are unchanged.
  • Dependencies and supply chain: PASS. Package pins, the 144 resolved archive integrity values, image digests, and action pins are unchanged.
  • System security: PASS. Pi remains non-selectable and outside the shipped and all-agent release cohorts; entrypoint privilege drop and limits are unchanged.
  • Testing and verification: PASS for the reviewed delta. The exact Pi artifact suite passed 27/27 at c62ae7049, git diff --check passed, the commit contains Prekshi Vyas's DCO, and GitHub reports the commit signature valid. Fresh CI is still running, installer-integration is failed, and human review remains changes-requested, so this review does not authorize handoff or merge.

Accepted candidate scope remains established by #7925 and #7926. Public activation remains owned by #7929 and #8818.

The code, security, and documentation impact reviews pass at c62ae7049, but the PR description needs three exact corrections before approval:

  • Check the sensitive-path review item and link the exact-commit security PASS: #9100 (review)
  • Replace 144-package lockfile in the documentation receipt. The lockfile has 145 package entries, including the root, and 144 resolved archives. Use SHA-512 integrity values for all 144 resolved archives. Replace the dash after the documentation path with a sentence or colon.
  • Replace exact-head Pi artifact contract (27 passed) with the exact command and commit: npx vitest run test/pi-candidate-runtime-artifacts.test.ts passed 27/27 at c62ae7049.

The receipt should retain Result docs-updated, Agent Codex Desktop, head marker c62ae7049, and AGENTS marker e30afb270. The complete reviewed evidence is that agents/pi/dependency-review.md matches the exact package version, integrity value, lockfile SHA-256, and SHA-512 integrity values for all 144 resolved archives. Pi remains non-selectable and outside the shipped and atomic release cohorts. The later CI-only commits do not change public behavior.

Do not mark the broad gate complete until the direct OpenClaw startup job finishes successfully.

## Summary

Model Router lifecycle operations could race across gateways or with
another onboarding run. Two processes could contend for one host port,
or destroy could stop a replacement router and overwrite its session.
Routed setup, resume, and teardown now serialize lifecycle work across
the current user's NemoClaw gateways. Destroy also verifies the captured
session before changing process or session state.

## Related Issue

Follow-up to #9112 and #9098.

## Changes

- During routed onboarding, hold the onboarding session lock, then take
the gateway route lock and current-user Model Router port lock through
setup and registry publication.
- During destroy, take the gateway route lock, then the current-user
port lock, then try the onboarding session lock without waiting before
rechecking the captured identity.
- Recheck the captured session identity before teardown and use an
atomic session comparison-and-swap for cleanup, preserving a
concurrently created same-name replacement.
- Preserve valid router recovery metadata when a same-name replacement
uses another port, and limit manual recovery instructions to the router
that destroy could not identify or stop.
- Bound registry peer discovery and represent either an unavailable
process inventory or a completed scan with no matching process.
- Signal only an ownership-verified Model Router process. Locking
serializes NemoClaw lifecycle work; teardown also rechecks command-line
ownership and refuses PID-based `SIGKILL`.
- Cover cross-gateway onboarding, resume, destroy, same-name
replacement, lock contention, inconclusive process state, and compiled
teardown behavior.

still matches the implementation. The latest merge adds only PR #9100 Pi
runtime and candidate-image files. Those files do not change the Model
Router lifecycle surface. The earlier PR #8908 trust merge also remains
outside this surface. The reviewed docs build passed with 0 errors and 2
existing warnings.

## Summary

Pi login and interactive Bash shells previously continued when
resource-limit enforcement failed. This change rejects shell startup and
reports the failed security control.

## Related Issue

Follow-up to #7925 and #9100.

## Changes

- Make both Pi system-wide Bash hooks exit when the resource-limit
helper is missing or enforcement fails.
- Add regression coverage for missing-helper, hardening-failure, and
verification-failure paths in login and interactive shells.

## Type of Change

- [x] Code change (feature, bug fix, or refactor)
- [ ] Code change with doc updates
- [ ] Doc only (prose changes, no code sample modifications)
- [ ] Doc only (includes code sample changes)

## Quality Gates

- [x] Tests added or updated for changed behavior
- [ ] Existing tests cover changed behavior — justification:
- [ ] Tests not applicable — justification:
- [ ] Docs updated for user-facing behavior changes
- [x] Docs not applicable — justification: Pi remains outside the
supported and selectable agent inventory. This change affects only a
fail-closed image control and its regression tests.
- [x] Sensitive paths changed (security, policy, credentials, preflight,
onboarding, inference, runner, sandbox, or messaging)
- [x] Sensitive-path review completed or maintainer-approved waiver
recorded — reviewer/approval link/justification: Independent Codex
Desktop review passed all nine security categories for commit under
review `e1947a586036b0f7577ce43e842888fe0e09ea33`. Both Bash hooks fail
closed when the helper is absent or hardening or exact verification
fails. The tests exercise each failure through shell behavior.
- [ ] Non-success, skipped, or missing CI check accepted by maintainer —
check name, approval link, and follow-up issue:

## Documentation Writer Review

- [x] Documentation writer subagent reviewed the completed changes
- Result: `no-docs-needed`
- Evidence: `agents/pi/Dockerfile.base` makes the Pi candidate image
reject Bash login and interactive shell startup when the resource-limit
helper is missing. The same hooks reject startup when hardening or exact
verification fails. `test/sandbox-rlimit-hooks.test.ts` covers these
paths. Pi remains outside `SHIPPED_MANAGED_IMAGE_AGENTS` and the public
supported-agent inventory, so no public documentation changes are
required.

## Summary by CodeRabbit

* **Bug Fixes**
* Improved shell startup security by stopping startup when
resource-limit hardening or verification fails.
* Missing security helpers now prevent shell sessions from continuing
instead of allowing startup with only a warning.

* **Tests**
* Added coverage verifying secure behavior for login and interactive
shells, including missing helpers, hardening failures, and verification
failures.
