LightCraft roadmap
Milestones toward full Adobe Lightroom parity (cloud Lightroom first, then every Lightroom Classic module), with wall-clock estimates for continuous (24/7) agent-driven development with 4–6 parallel agents. Estimates are calibrated on the sibling projects (DrawCraft reached its first four milestones in ≈ 4½ h) and are revised as milestones land.

Totals
| Target | Milestones | Wall-clock estimate |
|---|---|---|
| Cloud-Lightroom feature complete | M0–M11, M13–M14 | ≈ 130–180 h (6–8 days, 24/7) |
| Full parity incl. Classic modules and AI | M0–M16 | ≈ 200–300 h (9–13 days, 24/7) |
Risks that coding hours alone don't retire
- AI features (subject/sky/people masks, generative remove) need model weights with licences we can ship; classical fallbacks first. No permissively licensed sky-segmentation or raw-denoise model was found — we may need to train our own.
- Camera colour and lens data is a data problem: we never use Adobe's matrices, DCPs or LCPs. DNG-embedded data first, then our own calibration; long-tail camera/lens coverage grows over time.
- Legal decisions pending: whether GPL-licensed prose format descriptions (e.g. the public CR3 write-up) may be read by a designated engineer to produce an internal spec; freedom-to-operate review for local Laplacian filters, PatchMatch and HEVC (HEIC).
- Look parity with Adobe's default rendering is subjective tuning against our own reference targets.
Log
- 2026-09-30: roadmap created; M0 in progress; research docs (Lightroom reference, Rust imaging ecosystem) complete.
- 2026-09-30 (later): app running with the full Lightroom-style UI; pipeline v0; DNG/CR2/ARW; README showcase. ≈ 8 h elapsed.
