Prestige Barber Club v4.41.3 - Build Test Report

Scope:
- Member Validity: direct WhatsApp action per member.
- Member Validity: filtered WhatsApp broadcast queue.
- Member Validity: filtered VCF contact export.
- Member / Pra-Member / Non-Member: VCF contact export.

Static checks:
- PHP syntax lint: 201 PHP files passed before final partials update; partials.php re-linted separately and passed.
- contact_export.php emits vCard VERSION:3.0.
- Phone normalization uses application whatsapp_country_code and removes duplicate normalized numbers.
- Member Validity broadcast reuses whatsapp_broadcasts / whatsapp_broadcast_recipients with source_type=member.
- Filter criteria are carried from member_validity.php to broadcast/export.
- No destructive DB migration is required; schema release only moves to 4.41.3.

Limitations:
- No live production database/browser/WhatsApp client test was possible in the build environment.
- Broadcast queues a maximum of 2,000 valid recipients per campaign to avoid oversized shared-hosting requests.
