Consumed by visual_capture.gd's --scenario atlas_matrix mode. Every body/terrain_reference/system pair verified against server/data/systems.db (python3 read-only query, no sqlite3 CLI) — see docs note below for provenance.",

GJ380c gets 3 (Global/Region/District) since it is also the PR #212 cache-invariance-proof body (Hoshe's cold-vs-warm check on both the NEAREST/Global and LINEAR/District terrain-layer draw branches). GJ244Ad and GJ445c-m1 get 1 each (Global and Chunk respectively) — the curated pick, not an exhaustive per-body sweep. The full 6-rung x 7-body cross product (42 shots) is deliberately NOT curated here, matching T-1121's 'curated subset, not the full matrix' precedent; the full cross product remains reachable ad hoc via AtlasAgentInterface jump_to intents, not as a golden."
