Decode every raw encoding Panasonic and Leica bodies write, from the DMC-LX1 (2005) to the DC-S1RM2 (2025): compressed formats 4 (most bodies, 2008-2022) and 6 (S1 / S1R / S1H / S5, GH5M2), the prefix-coded strips of format 8 (GH6 and later), packed formats 2, 5 and 7, and the 16-bit words of the 2005-2007 .RAW files. Until now only format 5 decoded; every other Panasonic file opened as preview only. Clean-room: no raw-decoder source was read. Tag names come from tag documentation; every encoding was recovered by black-box analysis of 178 CC0 files from raw.pixls.us (118 bodies), and the module docs note the measurement that settled each rule. Format-8 tags of unknown meaning must carry the values every sample has, otherwise the file is reported as unsupported rather than guessed at. Levels and geometry: formats 4 and 6 store samples 15 above the recorded black level (files without one use 15); white is the active area's saturation plateau (the linearity limits are wrong on extended low-ISO shots, the GF1 and the Digilux 3); the in-camera aspect ratio is the default crop; mapped-out defect pixels are filled from same-colour neighbours; the CFA pattern applies at sample (0, 0). .rwl and .raw files are imported (engine, MCP folder expansion, file dialog, Linux MIME types). One file per encoding joins the never-panic proptest; 11 CC0 files join `cargo xtask corpus`, and corpus_panasonic_encodings checks each encoding's bit depth, black level, crop and CFA layout against the camera's own JPEG.
