Core Forms 4.3.4 | Gatilab Products

Two performance memoisations and three UX improvements layered on top of the 4.3.3 bug fixes. No breaking changes, no migrations.

cf_get_form() is request-scoped memoised. The same form requested multiple times per page (block render, get_html, action loop, analytics tracker) no longer re-fetches the post + meta and rebuilds the settings/messages arrays. Each call returns a clone so future callers can't poison the cached instance with property mutations. Invalidation: save_post_core-form (always) and *_post_meta hooks gated on get_post_type() so other CPT meta touches don't trash the cache.
cf_count_form_submissions() is request-scoped memoised. The forms list table called this per-row — a 50-form admin issued 50 COUNT(*) queries; now it issues one per (form_id, is_spam) pair and the rest are cache hits. Invalidated on cf_submission_inserted.

Block-editor preview skeleton. The Gutenberg block preview shows an animated shimmer skeleton (title bar → input rows → submit button) while ServerSideRender is fetching, instead of a bare spinner. Respects prefers-reduced-motion.
Cleaner form picker. The block's form-picker dropdown shows just the form title instead of \"Title (slug)\" — much cleaner when titles are distinct. The slug is still surfaced via the Edit Form deep link beneath the picker.
/ keyboard shortcut on the forms list. Press / or s to focus the search box. Standard list-UI shortcut (GitHub, GitLab, Linear, every modern dashboard). Skipped when an input, textarea, or contenteditable already has focus so it never hijacks typing.

The wp_cf_submission_replies table self-heal and the un-spam action-replay parity from 4.3.3 are untouched — verified 10 call sites still wired.

No data or schema migrations.
No breaking API changes.
The cache-invalidation hooks are guarded with function_exists('add_action') to match the existing convention in functions.php, so the file remains autoload-safe for standalone test environments.

151 unit tests pass.
PHPStan reports no errors.
Production zip ships at 815 KB with no test framework, no PHPStan, no composer.json.
block-form.js rebuilt; bundle still contains wp.serverSideRender and the new cf-block-skeleton styles.
