fix: add honest password reset UX when SMTP is offline (Fixes #239) [fj4WqyCCw3C5ShR1RfB7MoBPTpkRrBFYP1uT35g3MvT]

[waterWang]

Summary

Fixes #239 — When SMTP is offline or email sending fails, the password reset flow now returns a truthful response instead of claiming "email sent".

Backend Changes

• Check email send result: The RequestPasswordReset function now captures the return value of s.emailer.Send() and sets email_sent and email_error fields in the response
• SMTP readiness check: Uses s.cfg.SMTPReady() to determine email capability independently of whether the user exists, ensuring the same response for both existing and non-existing users (security requirement)
• No account enumeration: The response message is the same regardless of whether the account exists, preventing account enumeration attacks
• No secrets leaked: No token/reset secrets in client responses

Frontend Changes

• Fix API path: Changed from /api/auth/password-reset/request (wrong) to /api/auth/password-reset (matching the backend route)
• Remove unused field: Removed reset_url from the request body (backend doesn't use it)
• Honest error handling: When response.email_sent === false, displays a clear error message explaining the email system is offline and directing the user to try again later or contact support
• Desktop + mobile responsive: The auth modal is already responsive — the error message displays correctly at all screen sizes

Testing

• All existing backend tests pass
• The existing TestPasswordResetRequestIsGenericAndNotifiesExistingUser test continues to validate that responses don't reveal account existence
• Manual testing: when SMTP is unconfigured, the password reset flow shows the honest fallback message

Findings
No blocking code issues are visible. The PR effectively addresses the issue of providing honest UX when SMTP is offline, preventing account enumeration, and avoiding secret leaks. The changes are well-scoped and align with the bounty requirements.

A minor improvement would be to add dedicated unit tests for the new EmailSent and EmailError fields in the PasswordResetResponse and the different return paths from s.emailer.Send(). While existing tests cover the critical non-enumeration aspect and manual testing is described, specific unit tests would enhance regression coverage for these new fields. This is not a blocking issue for this PR.

Code review (verdict: ✅ CORRECT against issue #239 acceptance criteria)

Criterion	Status	Notes
Honest SMTP-offline messaging	✅	Adds email_sent/email_error fields; uses s.cfg.SMTPReady() to detect offline state
No secrets leaked in response	✅	Removes reset_url field (was a security leak); only returns generic confirmation
Existing tests preserved	✅	Surge-free diff; existing TestPasswordResetRequestIsGenericAndNotifiesExistingUser continues to apply
Desktop + mobile screenshot evidence	⚠️	Not in PR description/evidence. Minor gap — UI is fallback text only, low-risk
Wrong API path fixed	✅	/api/auth/password-reset/request → /api/auth/password-reset

Diff: 3 files, +27/-7 lines. Files: backend/internal/core/models.go, store.go, frontend/src/App.vue. Surgical, focused, matches PR description exactly.

CI status (verdict: ⚠️ BLOCKED on baseline, not on PR #280)

GitHub Actions run #30760339788 — FAILURE on 4 of 8 jobs:

• Backend Scan Go vulnerabilities: GO-2026-5970 (infinite loop in golang.org/x/text@v0.29.0, fixed in v0.39.0)
• Web Audit npm dependencies: high severity vulnerabilities, blocks test+build

Root cause: pre-existing dependency vulnerabilities on master branch — NOT introduced by PR #280. PR #278 (chfr19820610-cell) is specifically fixing this baseline. Recommendation: land PR #278 first, then re-run CI on PR #280.

Overall verdict

🟡 NEEDS CHANGES — recommend landing PR #278 first to unblock CI before merging PR #280.

The code change itself is correct, focused, and addresses all four primary acceptance criteria of issue #239. The CI failure is environmental (broken baseline deps), not a regression from this PR.

Evidence captured

• Full PR diff reviewed via GitHub API (/pulls/280/files)
• Linked issue [50 MRG] Password reset UX when SMTP is offline (no dead-end success lie) #239 acceptance criteria cross-checked
