Live round 2 (the real bug): every nature-overlay marker size was a raw
screen-space constant drawn inside _canvas, whose scale IS view_zoom —
at Lendel's orbital fit zoom (0.0063) a 2.2px trunk dot rendered at
~0.014px, invisible; the same code at District's 3.75 zoom produced the
correctly-visible mouth ring, which is why one capture worked and the
headline rung didn't. Fixed via AtlasWindowGeometry.zoom_compensated_
size() (pure, floor-guarded) wired through every radius/line-width;
basin FILL points are positions and correctly stay unscaled. Suspect
tile-mode-rung-detection was ruled out live (granularity_v2=Region
confirmed in tile mode) but pinned with a named regression test anyway.
+8 pure-function tests incl. a numeric pin of the pre-fix magnitude
(<0.02px at orbital zoom); revert-verified by name. Draw-smoke suite
documented as supplementary (the shared SubViewport background harness
can pass vacuously under X11 BadMatch — the pure suite is the gate).
Live round 3 (drive-script bug, no product change): the lead's scratch
drive passed the button LABEL to set_overlay_visible() and the unknown-
id guard silently no-op'd — but the chase banked a real pin:
test_set_overlay_visible_gen_basins_flips_gate_and_redraws_nature_
overlay (draw-counting spy per the cold-start precedent; is_queued_for_
redraw does not exist in this build). Revert-verified.
Basins verified live: 7 Lendel watershed boundaries render at the
ruling's alphas. Suites: viewer 76/76, geometry-nature 42/42, nature-
overlay 22/22, zoom-ladder 50/50, no regressions across the cluster.

New AtlasWindowNatureOverlay (Node2D on the viewer canvas, above
terrain): self-connects to the shared atlas_layers_received broadcast
(the established one-signal-N-consumers shape) and consumes the whole-
body layer1 skeleton per Tyre's carrier ruling — no windowed wire
touched. Coordinate chain layer1_pixel_to_world_m -> world_m_to_
district -> canvas-local lives in atlas_window_geometry as pure tested
functions; vertical convention (row 0 = North pole, wy increases
south) verified against the server's own pixel_to_world_m, pinned by
pole tests and revert-verified (sign flip fails them by name).
Araminta's per-rung presentation table implemented exactly: Region
full skeleton (radii 0.9/1.4/2.2, confluence 3.5, mouth double-ring),
District trunk-only 1.6px at 60% with mouths at full landmark styling,
Quarter off until T-1170 course invention; retired palette reused
verbatim; RVR on / BAS off / ATR off defaults; missing river_class
falls back to trunk. 58 new tests (34 geometry, 22 lifecycle, 2 real-
driver draw smoke actually rendered); 11 existing atlas suites
regression-free. atlas_window_viewer.gd runs 16 lines past the
advisory 1000-line cap on trivial wiring — accepted, rides T-1158's
decomposition.
