FlashRaw camera database

data/cameras.json is the single camera database for the whole library. It is compiled into static Rust tables by crates/flashraw-camera-db/build.rs; never edit generated Rust. Edit the JSON (or normalise it with flashraw camera-db generate). See docs/camera-db.md for the format and tooling.

Verification

tools/camera_db/rederive.py checks the entries against FlashRaw's decodes of the sample files (the CC0 raw.pixls.us corpus and real-world files) and regenerates the fields the files state or show: names, CFA, active area, masked areas, black and white levels, image areas, and colour matrices from camera-written DNG files. Values the files cannot supply (colour matrices of bodies that write no DNG, decoder parameters, entries without sample files) are kept as stored. flashraw camera-db coverage prints how many entries per make carry each kind of data, and docs/camera-db-audit.md lists, per field group and make, what the files reproduce, contradict or cannot derive.

Each entry's verification holds the number of sample files it was confirmed against, the largest sample value observed in them, and notes.
