The Build & Test, Architecture Overview, and Conventions & Patterns sections
were still the init template's "_Add your ... here_" stubs. Filled them in
from the code:
- No build/test tooling exists; documents the php -l quality gate and the
dev-router.php requirement for running the server locally.
- Describes the two-deployable split (WP plugin vs server/) and the
.gitattributes export-ignore rule that keeps them apart in release zips.
- Records the PHP 7.4 (plugin) / 8.1+ (server) version split that already
drifted once in 3c64dd8.
- Notes Gitea (not GitHub) as the remote, the three-file release bump, and
the open security beads to check before touching auth or the installer.
The managed beads integration block is unchanged.
