- Add a four-second arcade-style boot sequence followed by the Character / Nickname introduction. - Separate cabinet power-on from RFID credit and player Start. - Add operator Power on control and cabinet power-state reporting. - Prevent repeated power commands from restarting boot or gameplay. - Ignore RFID scans received before the cabinet is ready. - Add power-state, RFID, controller, and GPIO feedback regression tests. - Expand the master walkthrough with export, packaging, file transfer, fresh-Pi setup, RFID compilation, and end-to-end testing instructions. - Correct tester hardware documentation: BCM23/J20 drives an LED; physical buttons connect through a separate I2C1 input board. - Document operator-triggered power-on as the current test workflow and retain the temporary 2.4 configuration compatibility notes. - Record successful physical testing of power-on, RFID credit, and player Start. - Add an Odin integration README describing the proposed Rust/NATS bridge, shared messages, Flutter GM interface, autopilot sequencing, hardware ownership, and Starfish SSH-management role. - Define migration milestones and information needed from the framework owner; link the integration guide from the root README. Validation: 69 controller tests, 10 GPIO tests, Pac-Man power/RFID checks, managed-cabinet lifecycle checks, and visual screen inspection.
