Outcome

Hermes creates its fresh Kanban schema in one SQLite transaction. This avoids one synchronous disk commit for each schema statement during managed-image startup.

Reason

Hermes 0.20.6 opens the Kanban database in autocommit mode with synchronous=FULL, then calls conn.executescript(SCHEMA_SQL). Without an explicit transaction, SQLite commits each CREATE statement separately. Slow overlay storage can therefore keep the gateway outside the three-minute health gate.

#11170 fixed permission validation. It did not change this Kanban initialization path, so rebuilding the image exposed the existing startup delay.

Changes

  • Require the pinned Hermes source to contain one conn.executescript(SCHEMA_SQL) call.
  • Wrap that call with BEGIN IMMEDIATE and COMMIT during the image build, then compile the module.
  • Make the legacy root-entrypoint fixture clear inherited directory special bits with GNU chmod's five-digit form.

Verification

  • npm run validate:pr passed against canonical main at efd56a372999acc9d97936e9b30b2164743255a5.
  • npm run checks:repository and the exact E2E mock/live parity gate passed.
  • Focused e2e-support validation passed: 13 tests.
  • GNU coreutils 8.32 in Ubuntu reproduced 0750 -> 2750 and verified 00750 -> 750 from an inherited 03770 directory.
  • The diff contains no secrets, API keys, or credentials.

📝 Walkthrough

Walkthrough

The change adds atomic Hermes Kanban schema patching, Kanban image probes, portable build-context wiring, request-budget timeout handling, bounded MCP discovery retries, workflow coverage, and a VLLM test timeout.

Changes

Hermes Kanban schema patching

Layer / File(s) Summary
Schema patcher and transaction tests
agents/hermes/patch-hermes-kanban-atomic-schema.py, test/agents/hermes/hermes-kanban-atomic-schema-patch.test.ts
The patcher adds transaction boundaries, validates schema shape, supports idempotent execution, and exposes a CLI. Tests cover rollback, malformed input, and repeated application.
Image patch application and Kanban probes
agents/hermes/Dockerfile, agents/hermes/image-build-probes.py, test/agents/hermes/hermes-image-build-probes.test.ts
The image verifies and applies the patch, runs Kanban initialization and session-delete probes, validates SQLite integrity, and removes the patcher.
Build-context and workflow coverage
src/lib/onboard/experimental/*, .github/workflows/portable-profile-e2e.yaml, test/e2e/support/portable-profile-rootless-runtime-workflow.test.ts
The patcher is added to the portable build context and workflow path filters. Tests verify build-context inclusion and push and pull-request triggers.

Request reliability updates

Layer / File(s) Summary
Request timeout classification and test coverage
tools/e2e/base-image-publication.mts, test/e2e/support/base-image-publication.test.ts
GitHub requests distinguish remaining-budget aborts from other failures. The test uses a simulated clock before the deadline.
Bounded MCP discovery retries
test/e2e/live/mcp-bridge-tool-discovery.ts, test/e2e/support/mcp-bridge-tool-discovery.test.ts, test/e2e/RETRY_INVENTORY.md
MCP discovery retries eligible timeout and transport failures, records evidence, reports progress, and stops after fixture requests or terminal failures.

VLLM test timeout

Layer / File(s) Summary
Explicit preset test timeout
src/lib/inference/serving/host-local-vllm-selection.test.ts
The explicit preset resolution test uses the shared timeout helper with a 15-second timeout.

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

Merge Risk: 🔵 Low · up to c52da

This change improves Hermes schema initialization and E2E request reliability, but a request that expires while its response body is read may report an invalid-JSON failure instead of a budget-expiration failure. The impact is bounded to failure reporting and follow-up handling.

In `@tools/e2e/base-image-publication.mts`:
- Around line 914-917: Update githubRequest and its request budget handling so
the abort timer uses the same clock source as GithubRequestOptions.now, rather
than relying directly on AbortSignal.timeout. Inject or otherwise abstract the
timeout mechanism so custom now implementations can expire pending requests
consistently, while preserving the existing remaining-budget calculation and
requestUsesRemainingBudget behavior.
- Around line 928-930: Update the githubRequest response-body error handling so
an abort caused by the request budget remains classified as a budget-exceeded
error instead of invalid JSON; add coverage using a delayed response body that
triggers the timeout during response.json().

Approved commit 02820fb4ff4c0dca82190480c5c130df4148c238. The Hermes schema patch is checksum-bound, fails closed on upstream shape drift, exercises the packaged CLI, verifies SQLite integrity, and is removed from the final image. The OpenClaw deletion-race handling retries once only after trusted cleanup and an observed absence. All 68 current checks pass, including both exact MCP discovery passes and all-agent activation.

Non-blocking: CodeRabbit’s two open request-budget threads identify a test-clock seam and response-body failure-classification gap in the E2E publication helper. They do not affect the production schema fix or the retry safety in this change. A focused follow-up PR should unify the injected clock with the abort timer and preserve budget-exceeded classification during response-body reads.

Hermes sandbox-image evidence — c5a452840523c080103d5740e1a2b935604e4dd7

The requested sandbox-images-and-e2e validation is green for this exact candidate:

The retained root-entrypoint artifact reports status: passed, with every assertion true. Its phase evidence records:

  • clean root-entrypoint startup: passed in 5.424s
  • legacy state migration: passed in 5.357s
  • cleanup: passed

The earlier legacy-fixture failures were caused by GNU chmod preserving a directory's inherited setgid bit for both 750 and 0750. A disposable Ubuntu/coreutils 8.32 reproduction showed 750 -> 2750, 0750 -> 2750, and 00750 -> 750; the final fixture uses 00750.

Local gates also passed against canonical main at efd56a372999acc9d97936e9b30b2164743255a5: npm run validate:pr, npm run checks:repository, the exact mock/live parity gate, and 13 focused e2e-support tests.
