Summary

Captured accordion panels used to be saved with their closed-state class list, including Tailwind `hidden`. core/accordion opens a panel only by removing the `hidden` attribute, so the `hidden` class kept every panel invisible. AccordionPattern now works out the panel's styling from the recorded open-state class list and drops the classes that only the closed state has. This applies to item-level controls and title buttons alike. The toggle icon keeps its resting (closed) class list. The fix is committed locally as c767b7a5 but not pushed, because the branch has no upstream set.

What changed

• [operator-only reference omitted]
• php-transformer/tests/unit/accordion-item-level-control.php: the full captured shape now matches the real evidence (`faq-answer mt-4 text-gray-600 hidden` with open/closed class attributes). New checks confirm the saved accordion-panel keeps `faq-answer` and the other shared classes, drops `hidden`, and has no `data-blocks-engine-capture-disclosure-*` attributes. A title-button case checks the same rule. These checks fail on the old branch head (6 failures) and pass after the fix (94 assertions).
• `composer test:canonical` exits 0 with no failures.

How to test

1. Run cd php-transformer && composer install --no-interaction --prefer-dist --no-progress && composer test:canonical; expect passes as recorded by Cook's deterministic gate.

Compatibility

Only affects accordion panels that carry the capture's open-class attribute. Panels without it are lowered exactly as before. The toggle icon and heading presentation are unchanged.

• Base unchanged since verification: trunk remains at 20d8b2a.
• CI expected: Homeboy CI after push
• Candidate adoption provenance: the candidate was promoted from the recorded Cook task execution.
• Cook deterministic verification: 1 gate(s) completed green.
• Durable run execution: Succeeded
• Reviewer-resolvable evidence from source_refs[0]: Recognize accordion items whose own element is the disclosure control #3050
• Task objective: Continue PR Recognize accordion items whose own element is the disclosure control #3050 (issue Accordion items whose own element is the disclosure control are not recognized #3049) in this worktree. The accordion now converts on the real import, but every panel stays collapsed when its item is opened.
