- pipeline::optics::Warp: one inverse map (lens-corrected → source) inside the single geometry resample:
manual radial distortion, embedded DNG WarpRectilinear (per plane), per-channel lateral CA scale,
radial vignetting gain (manual + embedded FixVignetteRadial); all in normalized radii
- automatic lateral CA estimate: radial edge profiles matched sub-pixel per plane, robust LSQ fit of
displacement = α·r (cached per source)
- defringe: purple/green hue ranges (OkLab hue) desaturated next to high-contrast edges, width relative
to the image long edge
- "Enable Lens Corrections" applies only lens data embedded in DNGs (opcodes are no longer baked at decode;
stored on the photo record, on by default at import when present). No LCP data anywhere.
- new controls: optics.caRed/caBlue, defringe hue ranges; Optics panel: Manual sub-section, Defringe flyout
- tests: barrel grid straightened, CA removal (auto + manual), embedded corrections toggle/scale, preview vs
export resolution independence, CA estimator accuracy, orientation of embedded lens data

- catalog: Store trait (FsStore: temp+fsync+rename+dir fsync; MemStore),
Journal: CRC-checked JSON-lines op log with sequence numbers + atomic
snapshots; torn final record dropped and truncated, stale records after a
snapshot skipped, mid-log damage preserved as catalog.log.damaged-N.
- PushHistory op so each edit logs one history step (not the full history).
- engine: Session::open_library/persist/close_library; every top-level
command is fsynced before returning; presets.json + view.json;
library.info / library.compact commands.
- app: default library ~/Pictures/LightCraft Library (LIGHTCRAFT_LIBRARY or
--library DIR override), --memory for throwaway sessions, snapshot on quit.
- tests: proptest replay(log)==state with random snapshots/reopens, every
truncation of the last record, stale log, mid-log damage, FsStore, engine
restart without close.
