_draw() splits into two independent gates: the Layer-1-gated skeleton
path (Region chords, clip retained) and the NEW DistrictWindowLayer-
gated course path — build_course_render_plan() (pure, render-free-
testable) consumed by draw_polyline with _zs-compensated widths and
opacities from the Araminta revisit tables; mouth double-rings at
Mouth termini only (EdgeDrain/ContinuesBeyondWindow/None: three
meanings, one presentation — draw to last point, stop, documented);
zero water clip on the course path by construction (courses carry
rung-consistent termini). CourseTerminus wire vocabulary kept re-
pointable pending A2's real serde names; synthetic Ruling-3h fixtures
mean the suites need zero changes when the server payload lands. Real
gap found and fixed: window arrival never redrew the nature overlay
after the first fit (one line in _on_window_ready — courses would
miss every window swap post-pan). Water-clip header rewritten to
RESTRUCTURED status (retired on course rungs; permanent at Region
until Region goes windowed, T-1143 ruling 2). Revert-verified
(visibility-gate bypass -> 4 named failures). geometry-nature
112/112, nature-overlay 58/58, viewer 78/78, zero collateral; full
sweep 3928/3928 after the full-import bootstrap; gdlint clean (viewer
1016->1017, pre-existing overage rides T-1158).

B1 (Ruling 5c): nature block split out of atlas_window_geometry.gd
(954/1000 cap pressure) into atlas_window_geometry_nature.gd; RIVER_
CLASS_VISIBLE_BY_RUNG replaced by SKELETON_CLASS_VISIBLE_BY_RUNG
(Region-only now) + COURSE_CLASS_VISIBLE_BY_RUNG (District trunk+
tributary; Quarter all three — the pre-announced Quarter-rivers-
return) with width/opacity companion tables as Araminta's single
revisit point; deliberately opposite unknown-tag fallbacks per reader
(skeleton->full, course->empty), documented.
B2 (Ruling 5a): Region dot-scatter upgraded to connected chords via
river_downstream — D8 direction decode (0-7 into drainage.rs's
(row,col) delta table, antimeridian wrap-aware), sentinel chain ends
(MOUTH=8 ring-on-land, EDGE_DRAIN=9 no ring, TERMINAL=10 reserved,
decodes like EDGE_DRAIN so the future endorheic server needs no
client change). Pure build_skeleton_chords() split from drawing for
render-free testability. Chord clip rule (3g pick): segment clips if
either endpoint OR midpoint is drawn water — three-point catches both
narrow-inlet and long-chord failure modes at one extra lookup;
documented. Self-caught during build: first draft misdecoded the
pointer as a river_cells INDEX; rewired to direction decode against
A1's real convention before leaving the branch. Dual revert-verified
(direction sabotage -> 6 named failures incl. the chain-threading
pin; midpoint-drop -> exactly the 1 named clip test). Suites:
geometry-nature 86/86, geometry 130/130, nature-overlay 24/24; full
sweep 3892 with only the 6 known pre-existing garment/gait failures
untouched by this batch; gdlint clean.

Jeroen's hands-on report: rivers continuing under the ocean. Tyre's
ruling implemented: the skeleton is rung-independent, the drawn coast
is rung-indexed (warp cutoff admits more octaves per rung), so
reconciliation is a presentation-frame operation — a draw-time clip
against the SAME per-cell morphology verdict the terrain painter used,
at the rung on screen. New pure module atlas_window_water_clip.gd:
cell resolution across both paths (single-window direct; tile mode
selects the containing tile by each tile's OWN echoed n with nearest-
wrap re-expression against that tile's canonical center — response-is-
source-of-truth + wrap discipline reused, not reinvented). Strict drop
(no snap); offshore mouths suppressed (return with real termini in
T-1170 — retirement markers at the clip sites); basins untouched;
fail-open wherever no composite data has arrived (the clip refines
presentation, never gates data). The _pos split feeds the SAME wrap-
resolved district to both draw position and clip test so they can
never disagree about the wrap image. 49 new tests incl. antimeridian
and mid-progressive-arrival fail-open; revert-verified with precise
attribution (breaking water detection fails exactly the 3 water tests,
fail-open/land tests stay green); smoke-suite stub crash under a real
driver caught and fixed (headless skip-gating masked it). 7 suites
regression-free; gdlint clean.

I1: _draw_attractor_shape's three stroke-width args (Confluence arc,
Coastal/NaturalHarbor arc, Oasis spokes) were raw screen-space literals
— Godot multiplies stroke widths by canvas scale exactly like radii, so
at the Region orbital fit zoom the outlines rasterized at ~0.01px, the
identical sub-pixel class the dot/ring compensation fixed, missed on
glyph internals (and attractors are Region-only — precisely where it
bites). Widths now arrive pre-compensated via a px_w param, keeping the
primitive pure. Regression pin: a source-scan test asserting no
draw_arc/draw_line in the function carries a bare numeric width (the
draw-smoke suite documents its own vacuous-pass mode, so source-scan is
the environment-independent gate); revert-verified by name. I2: D-226
visibility-direction sentence — Araminta's fade-down inversion recorded
as pre-T-1170 with its single revisit point named. I3: class-header
call-site claim corrected (enter() funnels through _enter_at_rung).

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.
