* Unit tests for PR_Core_Verification_Scanner::compute_status().
|

*
|

* Run: php tests/unit/test-verification-scanner.php
|
||||
* Exit code 0 = all pass, 1 = any failure.
|
||||
*
|
||||
* What's covered:
|
||||
* - Empty last_verified → overdue.
|
||||
* - Days < 90% of threshold → current.
|
||||
* - Days >= 90% and < 100% of threshold → due.
|
||||
* - Days >= threshold → overdue.
|
||||
* - Boundary: exactly at 90% → due (not current).
|
||||
* - high velocity applies 60-day threshold from option.
|
||||
* - low velocity applies 365-day constant (not option).
|
||||
* - medium/default applies 180-day threshold from option.
