docs/sony-ilce7rm6-lens-corrections.md records the three Sony tables, the measured conventions with their residuals, the conversion to WarpRectilinear and its fit gate, the model allowlist and how to extend it, the measurement method, the verification and the limits. Verified locally on 54 ILCE-7RM6 photos with four lenses. The corrected render lines up with the camera JPEG within 0.679 px at 1440 px at the corners and edge midpoints of the 33 measurable photos shot with in-camera correction on (up to 17.3 px uncorrected). The 13 controls show the model's own shift. Every fit passes the 0.25 px gate (margin 0.075). Lateral CA stays within 0.3 px, but applied after demosaic it raises the render's corner CA (rms 0.032 -> 0.052 px); the doc and tracker say so. Its "Two conventions" section sets these conventions next to the ILCE-7RM4A's (vendor::arw_lens, docs/sony-lens-corrections.md, #498): on the 34 measurable ILCE-7RM6 photos that formula gives 1.429 / 0.319 px (max / rms) against 0.596 / 0.143, failing only on the 24-70 GM II and fitting the 100 mm and 200-600 better; no single unit fits every lens under either, and what would settle it (Sony On/Off exports of a wide zoom, more lenses). docs/sony-lens-corrections.md gains a pointer to it. Tracker rows LR-EDIT-OPTICS-PROFILE (one note for both bodies) and LR-IMP-CAMERA-COVERAGE in docs/parity-checklist.md, gap 8 in docs/gaps.md, the lens-profile section of docs/raw-parity.md (lens score unchanged), whats-new (lossless ARWs now; Compressed / Compressed HQ once the ARW 6.0 decoder, #625, lands) and the colour-fit follow-up note are updated.
