CCCT-2879 Show Expired Firebase OTP Codes As No Longer Valid

[conroy-ricketts]

CCCT-2879

Product Description

When Firebase discards a phone OTP code, the user is told it is no longer valid and offered a new code, not "wrong passcode".

Before:

Screen_Recording_20261007_142419_CommCare.Debug.mp4

After:

Screen_Recording_20261008_152246_CommCare.Debug.2.mp4

Technical Summary

Firebase gives no attempts count or retry wait, so a new code is offered immediately. Firebase test phone numbers never expire codes, so verify with a real number.

Safety Assurance

Safety story

What gives confidence

• I reached the expired state on a device with a real number and checked layout.
• Robolectric tests drive both Firebase errors through the real fragment.

Risks to review

• The rotation fix also changes the PersonalID out-of-attempts state from CCCT-2804.
• The button row moved to ConstraintLayout; long translations wrap instead of overlapping.

Automated test coverage

Unit and Robolectric tests cover both Firebase error codes, no PersonalID fallback, immediate resend, and the disabled field after rotation.

Suggested Review Order

Read commit by commit:

• e6e8494fc: classifies the expired-code error and shows it on the OTP screen
• 48aaea2e9: keeps code entry closed across rotation while the code is dead
• b07b21a4a: lets Request Code size to its label without overlapping Verify Code

📝 Walkthrough

Walkthrough

Firebase session-expired errors now map to a recoverable OTP error. The PersonalID verification screen displays an expired-code message, clears and disables code entry, and offers a new-code request. The screen preserves disabled code entry after fragment recreation. The change also adds translations, updates the verification-button layout, and adds tests and QA notes.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~15 minutes

Change: Bug fix

Suggested reviewers: jignesh-dimagi, shubham1g5

Merge Risk: 🔵 Low · up to f4cd1

The change shows an expired-code message and offers a new code. The release QA step tests the wrong scenario and should be corrected, but this does not affect runtime behavior.

- Line 46: Update the Firebase OTP QA step to test an expired code rather than
three incorrect submissions, and remove the unsupported claim that Firebase
tracks or exhausts attempts; keep the expected expiry behavior tied to an
actually expired code.

Wondering if we should also cherry-pick this to the 2.65 release?
