The repo's documentation framed it as a support repo for one product (WardenOS). Since going public the real audience is anyone with a Luckfox Pico 86 Panel: a maintained 6.18 kernel, an off-device development loop, and a device simulator that exist nowhere else for this board. Reframe the README and top-level docs board-first, with WardenOS documented as the downstream consumer it is (ADR-0008). Also an editorial pass over the whole doc set: - every H1/H2 is now a short title, not a sentence (ADRs, qemu/, patches/, drivers/, architecture, NPU feasibility, config-lint, payload); workflow flowchart titles fixed at the source in tools/flowgen.py and regenerated with fresh bench numbers - README Quick Start commands verified against the scripts; requirements corrected (curl, bare python, gcc >= 14) and the MC/DC gate added as a step (run green locally on gcc 14.2) - dropped the 'needs python (not python3)' vendor dig: build-kernel.sh inherited the same requirement (filed #10 to remove it) - glossed MC/DC and HPMCU on first use; marked the tests/uboot-ab reference as flare-edge; deduplicated the three-simulator list into the root README table
