"""W1 invariant tests for experiment_rooftop_spatial_resolution_plan (dry-run).

plan_v2.md §9 implementation guards:
- G1: active_status × plate_policy compatibility matrix.
- G2: evidence_ev_ids strict-lookup with missing emit.
- G3: shot_snapshot_hash canonical sorted JSON SHA256 determinism.
- G4: keyword whitelist incl "수리영 방"; "방" 단독 금지; "주방" room-node 제외.
- G5: gap_id naming convention (gap_room_<shot_id> / gap_camera_<shot_id>).
- G6: W2 separation — production schema/code 무영향.

Plus W1 invariants from next_session memory:
- 14 shots 모두 resolution_status. unknown 0.
- base_plate_binding null when unresolved. empty string forbidden.
- evidence_pointers relation ∈ {supports, contradicts, ambiguous}. 결론 문구 0.
- shot scope gap entries have single shot_id string. shot_ids array 0.
- BasePlateCluster master plate 필수. derived-only invalid.

No API calls, no DB writes, no image generation.
