- Introduced to define the development environment and validate runtime/platform contracts. - Enhanced with to ensure change markers adhere to publication rules. - Updated to integrate boot acceptance checks and ensure dependencies are correctly managed. - Added tests for environment validation, publication change scope, and CI stages to prevent regression and ensure compliance with publication standards. - Implemented checks in to validate the presence of development environment dependencies. - Refactored existing tests to improve coverage and ensure accurate validation of publication claims and software configurations.

SDIO0 provides *native SD command/data transfers* and descriptor-driven DMA through I/O gateway A.
|
|
Its signals share the GPIO alternate-function matrix. The card, pull-ups, bus voltage and board
|
|
timing are *external integration requirements*. Do not equate protocol support with a qualified
|
|
card-speed grade. SDIO1 uses the same controller family with a separate instance and pad group.
