dr-decode exposes four entry points rather than one decode, because callers differ sharply in what they need (ARCH §3.2): culling wants a preview, the grid wants metadata, only develop and export touch sensor data. Fusing them forces a full decode where a header read suffices, which is why Lightroom stalls ~2s per image while culling. Smoke-tested against 1,852 real Canon CR2 files (EOS 6D, ~27MB each): metadata 0.2ms from a 256KB header read, no full decode preview ~250ms 5472x3648, downscaled to 2048 for display jpeg 3.0ms Two findings worth recording: rawler 0.7.2's CR2 decoder implements only full_image; thumbnail_image and preview_image are unimplemented trait defaults returning None. So every rung of the preview ladder resolves to a full-resolution decode at ~250ms — 5x over NFR-P13's 50ms budget. CR2 does carry smaller IFDs, so the fix is our own IFD walk or an upstream contribution. The ladder is written now so that fixing it is a decoder change, not a change to every caller. Recorded in milestone-v0.1 risks. Preview.downscale_to bounds memory: a 5472x3648 RGBA preview is 79.8MB, which exhausts a phone's budget after a handful of images. Box-filtered so downscaled thumbnails do not alias. Also fixed a RefCell double-borrow that panicked on first navigation — `*x.borrow_mut() = *x.borrow() + 1` holds both borrows at once. Verified with 10,000 programmatic navigations. 58 tests passing. Traceability 20.3% (29/143).
