Outcome

Restore the trusted Hermes ACP qualification path on OpenShell 0.0.116. The Dockerfile-pinned Hermes base now passes the exact reviewed inventory check, and the live lifecycle accepts OpenShell's connection-refused response only when it proves the deliberately stopped gateway state.

Reason

Trusted main E2E run 34728523548 exposed two qualification-fixture mismatches before the required lifecycle could finish. The pinned Hermes base still records the reviewed deb13u4 Python security package accepted by PR #11634, while the shared inventory validator had advanced to deb13u5 only. OpenShell 0.0.116 also returns a structured connection error after the gateway is deliberately stopped instead of the older successful Status: Disconnected response.

Related issues

Changes

  • Accept the older reviewed security inventory only when resolver provenance proves the exact Dockerfile-pinned Hermes base image.
  • Recognize the exact OpenShell 0.0.116 stopped-gateway connection response without accepting timeouts, signals, or unrelated command failures.
  • Add deterministic coverage for both compatibility paths and their rejection boundaries.

Verification

  • Focused CLI validation — 29 tests passed.
  • Focused Hermes resolver integration — 6 tests passed.
  • Focused E2E-support ACP validation — 11 tests passed.
  • npm run test:e2e-phases:check — 134 live test phase plans passed across 87 files.
  • Broad base-image validation — 241 tests passed across 17 files.
  • NODE_OPTIONS=--max-old-space-size=8192 npm run typecheck:cli — passed.
  • npm run validate:pr — passed.
  • Commit and pre-push hooks — passed.
  • The diff contains no secrets, API keys, or credentials.

Review notes

  • Reviewed commit: bd330a4688da3802ce0a8e3cf3420c22840e0314
  • Sensitive path: src/lib/sandbox-base-image/security-inventory.ts
  • Method: author self-review, focused deterministic tests, exact pinned-image provenance checks, and comparison with PR fix(images): refresh trixie package pins #11634's reviewed dual-version Hermes inventory contract.
  • Outcome: arbitrary cached, local, override, and version-tag images cannot use the older inventory. The compatibility path is limited to the exact Dockerfile-pinned Hermes base, after resolver provenance has been proven.

Summary by CodeRabbit

  • Bug Fixes

    • Improved Hermes base-image validation to verify required security inventory, supported pinned package versions, and image provenance.
    • Improved stopped-gateway detection for clean disconnections and connection-refusal responses, while rejecting timed-out or signal-terminated commands.
    • Improved sandbox base-image validation consistency across local, pulled, overridden, cached, and pinned image sources.
  • Tests

    • Expanded coverage for security-inventory validation and base-image resolution scenarios.
    • Added end-to-end coverage for stopped-gateway response scenarios, including signal-terminated failures.

📝 Walkthrough

Walkthrough

The PR adds resolution context to sandbox image validation, supports Dockerfile-pinned Hermes security inventory validation, and centralizes stopped-gateway detection for Hermes E2E tests.

Changes

Hermes security inventory validation

Layer / File(s) Summary
Validation context and inventory contract
src/lib/sandbox-base-image/types.ts, src/lib/sandbox-base-image/security-inventory.ts
Adds source and pinned-reference metadata to image validation. Defines current and Dockerfile-pinned Hermes package inventories.
Base-image validation wiring
src/lib/agent/base-image.ts, src/lib/sandbox-base-image.ts, src/lib/sandbox-base-image/resolution-metadata.ts, src/lib/agent/base-image-hermes.test.ts, src/lib/agent/base-image-hermes-resolution.test.ts, src/lib/sandbox-base-image-*.test.ts, src/lib/sandbox-base-image/resolution-metadata.test.ts
Passes resolution metadata through validation. Hermes accepts the pinned inventory only with matching pinned provenance. Tests verify local, override, version-tag, and pinned validation calls and package requirements.

Hermes gateway stopped precondition

Layer / File(s) Summary
Gateway precondition helper and coverage
test/e2e/fixtures/hermes-acp-live.ts, test/e2e/live/hermes-e2e.test.ts, test/e2e/support/hermes-acp-live.test.ts
Adds a shared stopped-gateway predicate, uses it in the E2E test, and rejects signaled connection-refused results.

70-82: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject timed-out and signaled zero-exit probes

hermesAcpGatewayStoppedPreconditionPassed accepts Status: Disconnected when exitCode === 0 without checking timedOut or signal. The live Hermes E2E passes this result directly to the predicate before starting recovery, so an invalid probe can allow recovery to proceed. Require !result.timedOut && result.signal === null in the zero-exit branch.
