PHASE 2 — Write initial report to ${reportPath}:
Write every bug you found so far. Format each as:

- Severity: high / medium / low
- Evidence: what you observed

PHASE 3 — Interactive testing (targeted — max 15 commands):
- Test email: type "user@" (no domain) and blur — does it validate?
- Test quantity: clear the field entirely — check the total display
- Test credit card: type a 25-character string — check for overflow
- Submit the form with zip code empty — does it require zip?
- Submit a valid form and run $B console --errors
- After finding more bugs, UPDATE ${reportPath} with new findings

PHASE 4 — Finalize report:
- UPDATE ${reportPath} with ALL bugs found across all phases
- Include console errors, form validation issues, visual overflow, missing attributes

- ONLY test the page at ${targetUrl} — do not navigate to other sites
- Write the report file in PHASE 2 before doing interactive testing

Replace session-cookie auth with JWT tokens. Currently using express-session + Redis store.

## Changes
1. Add \`jsonwebtoken\` package
2. New middleware \`auth/jwt-verify.ts\` replacing \`auth/session-check.ts\`
3. Login endpoint returns { accessToken, refreshToken }
4. Refresh endpoint rotates tokens
5. Migration script to invalidate existing sessions

## Files Modified
| File | Change |
|------|--------|
| auth/jwt-verify.ts | NEW: JWT verification middleware |
| auth/session-check.ts | DELETED |
| routes/login.ts | Return JWT instead of setting cookie |
| routes/refresh.ts | NEW: Token refresh endpoint |
| middleware/index.ts | Swap session-check for jwt-verify |

## Error handling
- Expired token: 401 with \`token_expired\` code
- Invalid token: 401 with \`invalid_token\` code
- Refresh with revoked token: 403

## Not in scope
- OAuth/OIDC integration
- Rate limiting on refresh endpoint

Build a user dashboard that shows account stats, recent activity, and settings.

4. Add a settings panel
5. Use a clean, modern UI with cards and icons

Migrate user records from PostgreSQL to a new schema with better indexing.

You are on the feature/string-utils branch. The base branch is main.
This is a test project — there is no remote, no PR to create.

Run the tests first:
\`\`\`bash
cd ${triageDir} && node test/run.js
\`\`\`

The tests will fail. Now run ONLY the Test Failure Ownership Triage (Steps T1-T4) from the ship workflow.

For each failing test, classify it as:
- **In-branch**: caused by changes on this branch (feature/string-utils)
- **Pre-existing**: existed before this branch (present on main)

Use git diff origin/main...HEAD (or git diff main...HEAD since there's no remote) to determine which files changed on this branch.

Output your classification for each failure clearly, labeling each as "IN-BRANCH" or "PRE-EXISTING" with your reasoning.
