On Sunday, nightly 0.1.3-nightly.20261026.3705 opened to "T3 Code could not load" on every platform (#25294). The web bundle crashed at boot, and nothing in CI ever boots the built bundle. Browser tests run source modules, so the production chunk graph goes untested. #25295 fixed that bug and added a guard for chunk import cycles. Other boot-time crashes can still ship.

This adds apps/web/scripts/verify-built-boot.ts. It loads the built apps/web/dist in headless Chromium, with no server, and fails if the app shows its boot error instead of mounting React. It runs after the web tests in the CI "Test Web" job and in the "Release web tests" job, which a release must pass before it publishes.

Proof: the probe passes on current main. With Sunday's vite.config.ts (from 04a21bb1c1^), it fails with TypeError: Cannot read properties of undefined (reading 'map') in the icons chunk, the same error users saw.

Notes:

• With no server, the client retries its session for about 15s before it renders, so the step takes about 22s including the build.
• The release job builds without the release env (Clerk key), so the signed-in startup path is not covered.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR adds CI and release smoke testing for the built web client without changing shipped application behavior. The new verification script also adds a file-level static-analysis suppression, which requires human review under the applicable policy.

Walkthrough

The CI and release workflows now build the web client and check that the built client boots in headless Chromium. The check serves the built SPA, records browser errors, and fails if the expected boot result does not occur.

Changes: Built web client boot check

Layer / File(s)	Summary
Built-client boot probe apps/web/scripts/verify-built-boot.ts, apps/web/tsconfig.json	The script checks for the build output, serves the SPA to headless Chromium, records browser errors, and waits for a React mount or the boot-error control. The TypeScript project includes the script.
CI and release integration .github/workflows/ci.yml, .github/workflows/release.yml	Both web-test jobs build the web client and run the boot check after the existing web tests.

The description explains the boot failure problem, the new verification script, affected CI jobs, observed verification results, runtime impact, and an explicit coverage limitation. It does not use the template headings or state explicit maintainer approval, but it provides the required information in a focused form.
