Entry per Jeroen's 2026-07-21 revision: planetary heightmap is now
FIXED — all drag-pan/wheel-zoom input removed (set_view/get_view_*
capture API survives for the golden harness); hover shows a
not-to-scale bracket reticle with the real extent labeled (a true
n=32 rectangle is sub-pixel on the planetary canvas — the honest
representation given the morph transition is deferred), and a click
that misses every city marker descends (city-click wins — one
gesture, two contextual reads, no modifier). Descent pushes a new
'district' nav screen centered on the click point's DistrictPos via
atlas_descend_geometry.district_pos_at (the pixel-to-district inverse
of the server mapping, verified against scale.rs).
Regional mode: atlas_window_viewer draws the composite (morphology x
elev_q lightness base; temp/moisture/veg toggles — temp reuses the
region-ramp colorizer exactly; Marine=6 transparent; glaciation
always-on tint matching apply_ice_tint's REAL gate, None|Light no-op,
over the amendment's looser prose — documented); pan-on-held-composite
with edge-crossing refetch + border-fade during the queue-based
derive wait; zoom never refetches. atlas_window_cache: LRU keyed
(body_id, center, n), touch-on-read, evict-only, no freshness (D-227).
atlas_window_request mirrors the generation-proxy pending-retry shape
for None-until-derived. Codec: window params omitted from the wire
when absent — byte-identical for every existing caller.
Live-verified against the T-1137 server in-worktree: real round-trip
on a GJ380c coastal district (6 fields x 1024 cells), echo staleness
guard, genuine ~1.4s background-derive wait, pan-edge refetch to an
adjacent window, cache-hit on re-descent with zero network. Full
client suite 3194/3194; gdlint clean on all 18 files.
Open follow-ups flagged in-code: header location label always falls
back to coordinates (nearest-settlement needs a join the district
window does not carry); atlas_standalone.gd's 'atlas_app.gd is never
modified' doc line is now imprecise.

T-1118: gen_region_grid overlay (label TMP) — _draw_gen_region_grid
copies _draw_gen_district's self-contained mapping (dims from the
layer dict); mean-temp cold-to-hot ramp over -50..+50 C;
REGION_TEMP_NONE_DC airless sentinel = skip-cell (undrawn, never an
invented color); legend entry.
T-1119 (touch points 3-6): quarter_footprints protocol passthrough;
gen_l4_quarters overlay (label QTR) — density-scaled glyph anchored
on the L3 settlement dot joined by city_id, shape = dominant district
type (corner-tab/diamond marks for Commercial/Industrial/
Administrative), color = density ramp on the settlement-gold family,
zoom-gated at SETTLEMENT_LABEL_MIN_ZOOM; landmark/corridor counts
never drawn (D-226(d) tooltip-only ceiling); legend entry.
Structure: atlas_viewer.gd and protocol.gd were over gdlint's
1000-line cap before this batch; cleanly-separable responsibilities
extracted on existing precedent — atlas_generation_state.gd (per-layer
data + accessors), atlas_generation_proxy.gd (polling/retry/pending
machinery), atlas_overlay_colors.gd (pure ramp/shape lookups),
atlas_map_protocol.gd (atlas/starmap/citynames codec, the
browse_protocol.gd delegate pattern). Public APIs preserved exactly;
_gen_state stays a field default (RefCounted, pre-_ready safe) because
_ready()-construction breaks every bare AtlasViewer.new() test —
documented inline.
Tests: registration + round-trip for both overlays; pure-function
suites for the temp ramp (endpoints/midpoint/clamp/sentinel) and
quarter glyph (scaling, zoom gate, ramp, notch across all 9
DistrictTypes); Tier-2 replay asserts exact literals from the real
server-generated fixture incl. the airless sentinel. Color.lerp(a,b,
1.0) is not bit-exact to b — endpoint assertions use per-component
is_equal_approx. Full suite 3094/3094; gdlint zero warnings incl. the
two previously-over-cap files. Live capture: legend grows to 7
sections, TMP/QTR toggles clean against a live server.
