Smoke Lab — agent-driven browser runner (runbook)

Ticket: PAP-13350 (plan §D4 item 1). Companion script: tests/e2e/smoke-lab-browser-runner.mts. Scenario source of truth: tests/e2e/smoke-lab.catalog.tsdo not fork the step list.

This is the manual/agent counterpart to the deterministic Playwright CI mirror (tests/e2e/smoke-lab.spec.ts, S4). Where the CI mirror runs headless in a throwaway instance for a red/green gate, this runbook has a QA agent drive a real browser through the same P1–P7 lifecycle against a live instance, typing demo credentials into the fake OAuth provider's real consent page, and records every step + a viewable screenshot to the Smoke Lab results API so the run shows up in the Smoke Lab tab and the dashboard "Integration smoke" card.


0. The one hard prerequisite: a local_trusted, non-production instance

The Smoke Lab feature fail-closes on public exposure only (server/src/services/smoke-lab.tsassertEnabled()):

RequirementWhy
experimental.enableSmokeLab = truefeature flag (board experimental settings)
deployment exposure ≠ publicnever expose the fake OAuth provider / loopback MCP sidecars to the open internet

The auth mode (local_trusted vs authenticated) and NODE_ENV do not gate the Smoke Lab — a private box is a private box. Every smoke-lab service method calls assertEnabled(), so on a public instance you get 403 {"error":"Smoke lab is only available on private (non-public) deployments"} (or 404 Smoke lab is disabled when the flag is off).

The shared dev worktree service works as-is now. The Paperclip-managed dev service (pnpm dev, PAPERCLIP_DEPLOYMENT_MODE=authenticated + NODE_ENV=production, e.g. http://paperclip-dev:45439) is private, so it can run the Smoke Lab directly — just turn the flag on. (Historically it was blocked because the gate required local_trusted + non-production; that restriction was removed in PAP-13351.) The installed package on :3100 still may not ship the smoke-lab routes (404).

If you prefer an isolated, no-login throwaway instance, boot one exactly the way the e2e config does (tests/e2e/playwright.config.ts):

bash
export NODE_ENV=test PORT=3211 \
  PAPERCLIP_HOME=/tmp/pap-smoke-home \
  PAPERCLIP_INSTANCE_ID=pap-smoke \
  PAPERCLIP_CONFIG=/tmp/pap-smoke-home/instances/pap-smoke/config.json \
  PAPERCLIP_BIND=loopback \
  PAPERCLIP_DEPLOYMENT_MODE=local_trusted \
  PAPERCLIP_DEPLOYMENT_EXPOSURE=private
pnpm paperclipai onboard --yes --run    # serves http://127.0.0.1:3211, own embedded PG
# wait for: GET /api/health -> 200

In local_trusted mode there is no auth wall — board access is implicit, so plain curl/fetch with an Origin: <base> header is a board actor. On an authenticated instance (Tailscale dev, :45439) you instead log in — POST /api/auth/sign-in/email with QA creds — and carry the *.session_token cookie; board mutations also require the Origin header. A control-plane run JWT is NOT accepted by a separate worktree instance's DB — cross-instance tokens 403.


1. Auth model for the results API

Endpoint groupAuthzActor that works here
services/start, services/stop, install-fixtures, reset, services (GET)assertBoardboard only (local_trusted implicit board, or session cookie)
runs, runs/:id, runs/:id/steps, runs/:id (PATCH)assertBoardOrAgentboard or an agent run JWT
`oauth/authorizetokenuserinfo

So the hybrid the ticket asks for: start services / install fixtures through the board UI, post step results with the run JWT (or the board session on this instance). Screenshots become viewable in the UI by uploading each PNG as a company asset and putting its served URL in the step's screenshotArtifactRef.


2. Fixed fixture facts

  • Demo OAuth creds: [email protected] / smoke-password (SMOKE_LAB_DEMO_*). Email is pre-filled on the consent page; you type the password.
  • Fake OAuth scopes: only smoke:openid smoke:profile smoke:email are accepted — any other scope400.
  • Consent page: GET /api/companies/:cid/smoke-lab/oauth/authorize?client_id=…&redirect_uri=…&scope=…&state=…&response_type=code renders the "SMOKE TEST — not a real provider" login+consent form. Submitting valid creds → 302 to redirect_uri?code=… (wrong creds → 403). The redirect target is a dead loopback callback — don't wait for it to load; assert on the 302 + code= in the Location header, then let the failed navigation commit before driving the Paperclip UI.
  • Two connections per install: remote_http (HTTP MCP fixture, used for P1/P2/P5/P6/P7) and local_stdio (used for P3/P4). install-fixtures is idempotent.
  • Lifecycle tools (from the catalog): HTTP → read todo.list, write todo.add, deny email.send, quarantine fixture.schemaFlip; stdio → read time.now, write slow.ping, deny crash.now.

3. Per-scenario lifecycle (mirror the catalog — 8 steps)

For each ciSmokeLabScenarios entry, drive the browser + board API through:

  1. connect — start services + install fixtures; navigate the scenario's uiEntryPath (apps/advanced/review/activity/attention). For the P1 OAuth scenario, first open the consent page, type the demo creds, submit, and assert the 302+code.
  2. discover-catalogGET /api/tool-connections/:id/catalog; assert it contains the scenario's allowedRead tool; screenshot the connection UI.
  3. allowed-readPOST /api/tool-connections/:id/test-calls with the read tool; expect decision:"allowed", no error; confirm an audit row; screenshot Activity.
  4. ask-first-write-approved — create a require_approval policy (POST /api/companies/:cid/tools/policies), issue the write test-call (decision:"ask_first" + actionRequestId), open Review, approve (POST /api/tool-gateway/action-requests/:id/approve {companyId}), poll to done.
  5. denied-blocked-call — create a block policy, issue the denied tool; expect decision:"off" + error.reasonCode; screenshot Review.
  6. schema-change-quarantine — HTTP only: set config.quarantineNewEntries, allow + call fixture.schemaFlip, POST …/catalog/refresh, assert quarantinedCount > 0; screenshot Attention. (Non-HTTP records governance evidence via fixture metadata on Activity.)
  7. revoke — gateway scenario: create a run-scoped gateway session, list tools (200), revoke, re-list (401). Others: PATCH …/tool-connections/:id {enabled:false} then re-enable. Screenshot the connection.
  8. audit-evidence — re-assert the audit row; screenshot Activity.

Record each step: POST /api/companies/:cid/smoke-lab/runs/:runId/steps with { path, scenarioStep, status, detail, screenshotArtifactRef:{kind,url}, durationMs }. For a viewable screenshot: POST /api/companies/:cid/assets/images (multipart field file, PNG) → use <base>${contentPath} as the ref url.

Run lifecycle: POST …/smoke-lab/runs {trigger:"manual"|"ci"|"routine", summary} → record steps → PATCH …/runs/:id {status:"passed"|"failed", summary}. Finish by screenshotting /{PREFIX}/apps/advanced/smoke-lab (matrix + run history) and /{PREFIX}/dashboard (the "Integration smoke" card).


4. Run it

bash
# with the local_trusted instance from §0 already serving on :3211
node --experimental-strip-types tests/e2e/smoke-lab-browser-runner.mts
#   SMOKE_BASE=http://127.0.0.1:3211  (default)
#   SMOKE_COMPANY_ID=<uuid>           (optional; else a fresh company is created)
#   SMOKE_SHOT_DIR=/tmp/pap13350-shots

The runner launches real Chromium via the ARM64 wrapper (.paperclip/browser-runtime/chromium-arm64/bin/chromium-agent-browser) — see memory/agent-browser-arm64-chromium; on this aarch64 host the default puppeteer Chrome is x86-64 and won't launch. It prints the runId and a per-path step count and writes ${SHOT_DIR}/result.json.


5. Handling failures

A failing step is recorded with status:"fail" and its error/-failed.png, and the run is finalized failed. Triage each failure:

  • Product/UI defect → file a child issue assigned to the owning coder (S1/S2 for API/UI, S4 for the catalog/mirror), with repro + the failed screenshot, and set a blocker. Do not close S5 green over a real defect.
  • Runner/environment issue (selector drift, wrong scope, dead-callback race — all hit during first authoring) → fix the runner and re-run; don't file product bugs.

Never post a PASS if the UI was not actually exercised in a real browser (see the QA "Forbidden PASS shape" rule).
