feat(tuning): clip gold masks to the to-curb estimation geometry

chore(gold): additional hand-labeled lots

fix(tuning): label save-crash + export fusion panel + roadmap SAM3-CPU item

chore(tuning): finalize Douglas-only new-build gold list + label guidance + roadmap

feat(tuning): offline pipeline tuning suite (harness + gold labeler + Gradio cockpit)

docs+eval: statewide-parcels parity result (IoU 0.999-1.000, deltas <=0.1% on 8 metro addresses)

feat(exp4): owner-proposed cascade — EoMT primary, incumbent arbitrates sidewalk/earth (LAWN_CASCADE, off by default)

feat(exp4): Phase 1 bake-off — LAWN_MODEL override, EoMT-DINOv3 candidate, findings

feat(eval): labeled before/after eval harness + exp5 green-reclaim results

feat: street-aware right-of-way + per-extension size reporting (Phase 3.5)

feat: Sarpy County region (USGS 2016 LiDAR via TNM) + HTTP resilience

refactor: ports + adapters + estimation-strategy chain (Douglas only, byte-identical)
