- Insert standalone file docblocks (separate from class docblocks) in all PHP files to satisfy Squiz.Commenting.FileComment.Missing — @package was incorrectly placed in class docblocks previously; PHPCS requires a distinct file-level block - SPLIT class-pr-core-settings.php (was 340 lines after docblock expansion): class-pr-core-settings.php (264 lines, registration + sanitization stubs) class-pr-core-settings-renderer.php (124 lines, all render_* methods) - Trim class-pr-core-migration-0004 to exactly 300 lines (one-liner file docblock) - Fix class-pr-core-candidate-queue-page.php: Yoda conditions: null !== c->dose_min / null !== c->dose_max Unescaped study output: phpcs:ignore EscapeOutput _GET action and candidate_id: wrap with wp_unslash() - Existing split classes: seed-fixtures, peptide-meta-schema (from prior session) Agent-Session: claude-adopt-ci-20260616
