### Problem/Motivation Replace integer #access values in render arrays with proper booleans. Drupal deprecated passing non-boolean, non-AccessResultInterface values to the #access render array key in Drupal 11.4.0, converting non-zero integers to true and 0 to false while leaving variables and AccessResultInterface expressions untouched. ### Proposed resolution Handled automatically by drupal-rector via the `ReplaceNonBoolAccessRector` rule. ### How this rule was built This rule was produced with an AI-assisted workflow in which every step was verified manually by @bbrala. Its logic started from the matching drupal-digests entry, which was adapted to drupal-rector's conventions — a dedicated rule or an existing upstream rule configured into the Drupal 12 set — and covered with before/after test fixtures. Backward-compatibility was assessed and version-gated: safe rewrites are applied directly, while unsafe ones are wrapped via `DeprecationHelper` or moved to an opt-in breaking set. The rule was then live-tested against a set of contributed modules; where no contrib call site could be found, a static code sample was written in a test module to exercise it. A final automated QA pass covered type-guard, fixture coverage, BC-decision, registration and idempotency checks. ### References - Related issue(s): [#3526250](https://www.drupal.org/i/3526250) ### Work items - Commit(s): [f58f6aaf7c](https://github.com/palantirnet/drupal-rector/commit/f58f6aaf7c9e) ### Credit - Implemented by: @bbrala - Reviewed / helped by: @mglaman --- *Filed retroactively as part of the Drupal 12 rector coverage effort.
