=== COMMENTED-OUT CODE ANALYSIS ===
|
|
|
|
Documentation comments found (all legitimate):
|
|
- File headers (ticket references, explanatory text)
|
|
- JSX element comments (UI layout notes)
|
|
- Inline comments (edge case explanations)
|
|
|
|
✓ No substantial commented-out code blocks (>3 lines) found
|
|
Status: CLEAN
|
|
|
|
=== TODO/FIXME COMMENTS ===
|
|
|
|
Searched for TODO/FIXME markers across feature files:
|
|
✓ None found in feature files
|
|
|
|
The comment at lib/actions/forgot-password.ts:549 regarding OTP purge job:
|
|
"The purge job (app/api/cron/purge-sessions) should be extended, or a
|
|
companion cron added, to sweep rows WHERE expiresAt < NOW()."
|
|
- This is a documented future enhancement, not a blocker for current ticket
|
|
- Status: NOTED (future work, not required for #3273)
|
|
|
|
=== DUPLICATE COMPONENTS ===
|
|
|
|
Checked for duplicate component definitions:
|
|
✓ components/auth/ResetPasswordForm.tsx — auth variant (this ticket, step 3)
|
|
✓ components/forms/ResetPasswordForm.tsx — profile variant (pre-existing, ticket #3246)
|
|
|
|
These are intentionally distinct:
|
|
- Auth variant: OTP-based reset (no current password field), uses resetPasswordViaOtp action
|
|
- Profile variant: authenticated change-password (requires current password), uses changeMyPassword action
|
|
- Used in different flows (reset vs. profile update)
|
|
Status: INTENTIONAL, NOT DUPLICATES
|
|
|
|
=== DEAD BARREL ENTRIES ===
|
|
|
|
Checked index.ts files for dead re-exports:
|
|
✓ No barrel files (index.ts) in the feature-file scope
