 ## [Unreleased]
 
 ### Added
+- **The Atlas remembers across restarts** (D-255, T-1183) — every map view you visit is now kept on disk as well as in memory: relaunch the game, reopen a body, and previously-visited zoom steps draw instantly from the local cache with no server round-trip — only genuinely new ground fetches. Storage stays tidy on its own: fine-grained views of a body you haven't visited in ~two weeks quietly reclaim their space, each body's deep-zoom footprint is capped, and the whole-body overview of every visited body is kept forever. The cache is update-safe by construction — entries from an older game version are silently refetched, never misread
 - **The stepped Atlas map** (D-255, T-1182) — the body map is rebuilt on the step-canvas pipe: opening a body lands on the whole-body Global view, and the mouse wheel walks six discrete zoom steps (Global → Region → District → Quarter → Block → 64 m Chunk), cursor-anchored, with edge-scroll and WASD panning and a hard full-zoom-out snap back to Global. Terrain draws texel-exact from the server's data canvas (no client-side scaling — the whole family of zoom-compensation bugs is structurally gone, ~9,400 lines lighter), while river courses and settlement markers stay crisp at constant pixel sizes on a separate annotation layer. While a new step loads, the previous view holds with a pending wash — no blank frames. Within one session, revisited views come from an in-memory cache; the disk cache that survives restarts is the next ticket (T-1183)
 - **Lakes now show whether they drain** (D-227, T-1185) — every overflow lake's exit river is wired into the served course network: where a basin fills past its spill point, the water's escape path appears as a real river continuation (most commonly a short spill onto adjacent open ground — the honest dominant pattern; a long dramatic exit river to the sea is the exception). A closed (endorheic) basin gains nothing — the absence of any outgoing course IS the signal, exactly as ruled: no extra data bit, just hydrology you can read off the map
 - **Step-canvas serving — the map's new data pipe** (D-255, T-1181) — the server now answers "what is at this world coordinate at this zoom step" as a single tagged message per step: all six Atlas ladder rungs (the whole-body Global opener down to 64 m Chunk) served through one StepCanvasRequest/StepCanvasResponse envelope, with dense terrain fields shipped as compact per-field PNGs and river courses/cliffs as native lists (the encoding the workshop measured smallest-and-fastest). Backed by a keep-always whole-body tier (~9 MB for all ~267 bodies) plus a per-rung cache with honest freshness rules (terrain never goes stale — only storage evicts it; seasonal/tidal planes carry real clocks). Byte-identical cache-hit-vs-miss is enforced by a dedicated acceptance test on every rung — the guarantee that a player walking somewhere without ever opening the map gets the identical world. River detail at deep zoom is capped at the density that already reads well one rung up, eliminating a measured 38-87% derive-cost penalty with no visible loss. Server side only — the client map component that draws these canvases is the next ticket (T-1182)
