AtlasLayerRequest gains window_center/window_n (serde-default, absent = whole-body, wire back-compat; demux untouched — up_to stays the discriminator). DistrictWindowLayer echoes center/n + six parallel arrays (morphology, elev_q, temp_dc i16 with the region sentinel, moisture_q, vegetation incl Marine=6, glaciation). Serving per the amendment's binding model: NEVER inline — GenWorkItem::DeriveWindow rides the Rayon queue, completion drain caches into DistrictWindowCache (bounded FIFO 256; no staleness by D-227 purity, capacity bound only), serve_district_window polls the cache and returns Pending-shaped None until derived. Per-connection coalescing: submit_window supersedes a still-pending item for the same (ConnectionId, body) — the surviving item is the newer one, proven by dedicated tests. TerrainAnalysis decision (option b, numbers in ticket/PR): re-derive via run_layer1 in the DeriveWindow branch rather than caching ~1.5MB x 50 LRU slots (~100MB permanent, the exact D-203 bloat T-1044's own text guarded against); ~45ms one-time on the Rayon path, invisible to the tick thread. T-1044 confirmed within-cascade-only (cascade.rs:358 still drops the analysis before BodyWorldState) — the fork was open. Window derive loop promoted from aliveness_probe::render_window_panels; determinism promoted from probe-only proof to a real test (two passes byte-identical). New fixture atlas_response_ready_with_window exercises all six arrays incl. the airless sentinel and Marine; three existing fixtures gain district_window: None. Server clamps window_n to 1..=DISTRICT_WINDOW_MAX_N=64 (never trust the wire). 1774/1774 lib + 19/19 bridge_tcp green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
