CRITICAL IDENTITY FIX:
Ensures all member-generated content (Meetings, Posts, Comments) is explicitly linked to the creator's Novi UUID via 'external_person_id' at the moment of creation.
Changes:
- Added 'external_person_id' to creation payloads in Recovery Meetings and BB Posts.
- Implemented 'identity scavenging' from localStorage in submit handlers to prevent race conditions where Svelte stores are briefly null.
- Refactored Post Comment edit component to robustly initialize and save creator identity.
- Added 'The Novi UUID Rule' to IDAA documentation to mandate this pattern for future development.
- Added Playwright test to verify creation linkage and fixed a version-mismatch bug in the test auth helper.
Note: Archives and Archive Content are excluded as they do not require member ownership.
