Root had grown to 30 entries, most of it generated output and one-off scripts. It now holds 12. Docs: - Merge HARDWARE_SETUP, HARDWARE_PINOUT, GPIO_BUTTONS and ACCELEROMETER_PAGE_FLIP into a single docs/HARDWARE.md - Move ARCHITECTURE, REQUIREMENTS and HAL_IMPLEMENTATION_SPEC to docs/, leaving only README.md in the root - Update cross-references in README, setup_rpi.py and install_hardware_drivers.sh, and re-base ARCHITECTURE's source links Merging surfaced three errors, reconciled against hardware_config.json: - The power button was documented as GPIO 21 to GND with a pull-up. It is active high (pull_up: false); wiring it as documented reads as permanently pressed. - GPIO_BUTTONS used GPIO 23 for next-page; it is GPIO 27. - The FT5316 INT pin was routed to GPIO 27, which collides with the next-page button. Now documented as a conflict. Scripts: - Move debug_overlay_links.py and debug_previous_page.py to scripts/debug/ - Rename test_pagination_visual.py to scripts/debug/visualize_pagination.py; it renders output and asserts nothing, so the test_ prefix was misleading - Fix the __file__-relative paths these three relied on - Track update_pyweblayout.sh under scripts/ Tests: - Reword the backward-navigation tests, which described a pyWebLayout bug that is now fixed, as regression tests Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
