+Checkout: `bell-stack-parallel-89954b6`, branch `shriyatheunicorn/parallel-public-web`,
+base `89954b6429ce65dbb0a15646f08a993427d732f4`. Changes are local and uncommitted.
+No deployment, push, or pull request was created.
+
+## October 29 rerun
+
+The fresh production build and authenticated UI E2E passed, including both concurrent
+conversations, interrupted-stream recovery, citations, browser handoff, and confirmed cleanup.
+The runner now rejects configured credentials in conversation snapshots and rendered HTML.
+The same-session restart regression passed in two separate processes with confirmed cleanup.
+The full local fixture suite again passed 437 tests; typecheck, lint, and build passed.
+
+The unused-code review found active callers for all new named exports and confirmed both
+research tools in the compiled Eve manifest. The 667-file scan of tracked/non-ignored source,
+client assets, and bundled server code found none of the three configured service keys in raw,
+URL-encoded, or base64 form. Two private-key-pattern matches were dependency parser markers,
+not key material. The fresh dependency audit reported zero known advisories. `.env.local`
+remains ignored and mode 600. No production code changed during this rerun.
+
+Initial sandbox runs were unable to access local sockets, Chrome, or Browserbase; the enabled
+runs passed. The first new credential assertion falsely classified `ONEPASSWORD_ENABLED=false`
+as a secret. Credential-variable selection was corrected before the final successful UI run.
+
+## Failure coverage
+
+The new regressions reproduced and fixed two production issues: cancellation could leave a
+stalled Parallel response reader pending, and canceled browser startup could continue launching,
+initializing Stagehand, or retrying. Reader cancellation now releases the lock; startup checks
+cancellation after asynchronous boundaries and releases late sessions before settling.
+
+The normal suite covers disconnected/truncated JSON, stalled reads, timeout/abort propagation,
+401/403/429/500/502/503/504 responses without automatic research retries, response/input budgets,
+isolated concurrent research, and cancellation during Context allocation or browser launch.
+Existing cleanup regressions retain the hosted session ID when release fails so cleanup can retry.
+
+The automated production-build browser run passed on October 29
+in San Francisco. Both concurrent UI conversations returned cited research and completed the
+browser handoff. A synthetic interruption of one live response stream recovered within six
+stream requests without repeated tool calls. Missing/invalid operator credentials returned 401;
+an authenticated cross-origin write returned 403. UI retirement released both hosted sessions
+before fallback cleanup, and deletion of both disposable Contexts was confirmed. Evidence is in
+`.bell/parallel-e2e/8df88b57-f5f9-4aa9-8136-8ca22cabd9d0/` in this checkout, rerun after the
+restart patch and fresh production build.
+
+The security review reproduced Playwright route overrides forwarding synthetic authorization
+across redirects. The runner now pauses every request and redirect through CDP, authenticates
+only the exact configured origin, blocks other origins, and disables service workers. A Chrome
+regression confirms the intended server receives the credentials and the redirect target is never
+contacted. This change affects the test runner, not Bell's production authentication.

+| `tests/link-oauth.test.ts` | 24 | Passed with disposable PostgreSQL |

+| `tests/browser/captcha-live.test.ts` | 1 | Passed with hosted synthetic CAPTCHA events |
+| `tests/browser/context-save-real.test.ts` | 1 | Passed with hosted synthetic cookie persistence |
+| `tests/browser/proxy-location-real.test.ts` | 1 | Passed with hosted proxy configuration |
+| `tests/browser/browser-restart-real.test.ts` | 2 | Prepare and cross-process resume passed after the pinned SDK patch |
+| `tests/browser/onepassword-login-real.test.ts` | 1 | Not run: dedicated vault credentials/fixture unavailable |
+| `tests/browser/recaptcha-real.test.ts` | 1 | Not run: real Google CAPTCHA solving is outside this research integration |
+| **Total** | **60** | **58 passed, 0 failed, 2 not run** |
+
+The final combined normal/fixture run passed **437 tests**, with **7 opt-in hosted tests skipped**.
+Those seven are accounted for separately above. Across all distinct
+Vitest cases: **442 passed, 0 failed, 2 not run (444 total)**. This aggregate includes the Context,
+CAPTCHA-marker, and proxy hosted fixtures last run October 28; those three were not repeated on
+October 29. Type checking, unused-local/parameter
+checks, lint, and the production build pass. Live UI E2E is a separate script, not a Vitest case.
+`pnpm audit --json` reports zero known advisories in the locked dependency tree. Dependency
+versions are unchanged. The manifest and lockfile pin a small Stagehand recovery patch; no packages
+were added. The three configured
+service-key values were absent from the changed source and client build assets, and the Parallel
+endpoint/key name was absent from client assets. These scans do not detect arbitrary unknown secrets.
+
+## Restart failure resolved
+
+Three live attempts reproduced the original cross-process restart failure.
+The original session was still running before resume. Stagehand 4.3.0 rejected creation against
+the retained initialized extension with `A Stagehand instance is already initialized`; Bell then
+released it and created a replacement, losing the prepared page. Bell now uses a version-pinned,
+opt-in SDK patch to dispose only the stale Stagehand instance before initialization. The existing
+runtime operation preserves the browser and shares the initialization deadline. Default SDK
+behavior remains unchanged. See the [patch contract and maintenance requirements](../patches/README.md).
+
+Three cross-process runs now pass. The strengthened regression confirms the original session ID,
+prepared page, and successful OTP submission without closing Stagehand in the first process.
+The final run additionally checks the default SDK guard and rejects the recovery option on a
+fresh launch. Session release and deletion of the test-owned extension are confirmed. Evidence:
+`.bell/restart-e2e/8a014c46-e779-45b0-b695-c9c43b941e46/result.json`.
+
+## Outstanding release gate
+
+**Hosted staging is not certified.** A designated staging URL/project remains unconfirmed.
+The authenticated production build was tested locally against real Parallel and Browserbase;
+this does not verify deployed Eve routing, deployment protection, or the staging environment.
+The staging-capable runner and required configuration are documented in [provider tests](provider-tests.md).
+
+These checks do not establish zero defects or zero vulnerabilities. The CAPTCHA fixture is not
+a real solve, synthetic checkout is not a payment, and the two-conversation test uses one trusted
+operator rather than proving multi-tenant isolation. Research citations are checked for source
+provenance, not independently fact-checked for semantic correctness.

+# Public-web research with Parallel
+
+Set `PARALLEL_API_KEY` in the server's ignored `.env.local` and restart Bell. Use a key from
+the BELL app in your Parallel workspace; configure its monthly budget there. Set the same
+server-only variable in each deployment environment. No additional package is required.
+Without a key, research tools return a configuration error; browser tools remain available.
+
+`web_search` calls [Parallel Search](https://docs.parallel.ai/search/search-quickstart) at
+`/v1/search` in `fast` mode with 1–3 keyword queries and an objective. It returns five results
+by default, up to ten. `web_fetch` calls [Parallel Extract](https://docs.parallel.ai/extract/extract-quickstart)
+at `/v1/extract` for up to five public URLs with an objective. Advanced options are nested
+under `advanced_settings`. These tools run on the server and share no browser state with Parallel.
+
+Each request has a 30-second deadline and follows Eve turn cancellation. Responses exceeding
+1 MiB are cancelled before JSON parsing. There are no automatic
+retries or API redirects. Source URLs, titles, publication dates, and excerpts are retained;
+excerpts are capped at 2,000 characters per search result or 6,000 per extracted page, and
+16,000 per call. Local caps apply even if the provider exceeds the requested limits.
+The result reports truncation, provider warning count, and per-URL extraction errors.
+Raw provider error bodies, warning details, and authentication headers are never returned.
+
+Use Parallel for public evidence; cite source URLs and check incomplete results. Retrieval
+time is not a freshness guarantee. Use Browserbase for live availability, authentication,
+forms, and actions, under Bell's existing credential and payment rules. The URL validator
+rejects IP literals, credentials, common authentication/signature query parameters,
+custom ports, and obvious local/internal hostnames. Fragments are removed before transmission
+and from source URLs; public query strings remain supported.
+It cannot identify every private URL or secret in a path or query: never include those URLs or private data
+in research inputs. The provider may fetch source pages; this is not a cache-only integration.
+
+Run `pnpm check` for credential-free regression checks. See [provider checks](provider-tests.md)
+for the opt-in live research-to-browser test. Task API and background research are outside
+this integration.

+## Parallel research to browser
+
+Keep `OPENAI_API_KEY`, `PARALLEL_API_KEY`, and `BROWSERBASE_API_KEY` in an ignored
+`.env.local`. Install Chrome locally, or set `TEST_CHROME_PATH` to its executable.
+Build and test both production services with one command:

+```
+
+The launcher starts the compiled Eve agent and Next production server on loopback with

+It requires the built Eve rewrite port to be free and stops both owned services afterward.
+`next start` alone does not start the separate Eve service in this checkout.
+
+The Playwright test submits two concurrent conversations through the UI. Each must call
+Search, Extract, run, and snapshot exactly once, cite evidence from both research tools, and
+observe example.com's title in its own hosted browser and disposable Context. One UI response
+stream is deliberately interrupted; recovery must preserve the answer, reconnect within six
+stream requests, and avoid duplicated tool calls. The other conversation must remain healthy.
+Conversation snapshots and rendered HTML must not contain configured server credentials.
+
+The authenticated run rejects missing/invalid credentials and cross-origin writes. Clicking
+**New conversation** must retire the old Eve session and release the hosted browser before
+test cleanup intervenes. Cleanup then confirms temporary Context deletion. Screenshots and a
+sanitized JSON report are saved under ignored `.bell/parallel-e2e/<run-id>/`. Failures, including
+cleanup failures, exit nonzero. Normal `pnpm check` does not make these paid live calls.
+
+To test an already running development instance, use `BELL_LIVE_PARALLEL=1 pnpm test:parallel:live`.
+The default origin is `http://127.0.0.1:4320`; override with `BELL_TEST_ORIGIN`.
+
+### Hosted staging
+
+Use an explicitly designated, isolated staging deployment. Set its server environment to the
+three service keys above, `BELL_OPERATOR_USERNAME`, and a `BELL_OPERATOR_PASSWORD` of at least
+32 bytes. The runner needs the same operator credentials and a Browserbase key for the same
+test project. Supply an existing deployment-protection bypass as `BELL_TEST_PROTECTION_BYPASS`
+when required. Keep these values in a secret store or ignored environment file, not shell history.
+
+Set `BELL_TEST_ORIGIN` and `BELL_TEST_STAGING_ORIGIN` to the exact same HTTPS origin, then run:
+
+```sh
+BELL_LIVE_PARALLEL=1 pnpm test:parallel:live
+```
+
+Credentials are attached only to that exact origin; cross-origin UI requests are blocked.
+This checks an existing deployment and does not deploy, edit its environment, or disable its
+protection. A loopback production-build pass does not certify hosted routing or configuration.
+Build from source on the deployment platform; the local build includes native macOS dependencies.
+See [the verification record](parallel-verification.md) for current results and outstanding gates.
+
+## Isolated database and browser fixtures
+
+Set `TEST_LINK_DATABASE_URL` and `TEST_ONEPASSWORD_DATABASE_URL` to a disposable PostgreSQL
+database, never a production database. The suites create and remove their own fixture schemas.
+With Chrome installed, the following enables the original 53 database/browser skips and the
+new synthetic cross-origin credential-redirect regression alongside the normal suite:
+
+```sh
+BELL_TEST_LOCAL_CHROME=1 TEST_LINK_BROWSER=1 pnpm test
+pnpm typecheck
+pnpm lint
+```
+
+The database variables must be exported before running this command. These fixtures exercise
+OAuth/storage/privacy and synthetic checkout/autofill behavior; they do not charge a card or
+access a real vault. Provider outages, interrupted JSON bodies, stalled-reader cancellation,
+and cancellation during hosted-browser startup run without credentials in the normal suite.
+
+## Browser worker restart
+
+Load `BROWSERBASE_API_KEY` from ignored `.env.local`, then run:
+
+```sh
+BELL_LIVE_RESTART=1 pnpm test:browser:restart
+```
+
+This prepares a synthetic OTP page, exits the first process without closing Stagehand, and
+resumes from its saved session ID in a second process. It verifies the same browser and page,
+the OTP action, default SDK behavior, and confirmed session/extension cleanup. Reports are
+saved under ignored `.bell/restart-e2e/<run-id>/`. It does not use a real login or vault.
+The pinned [SDK patch](../patches/README.md) is applied by `pnpm install --frozen-lockfile`.
