Cover-fit: fit_window_view zooms from the viewport's LARGER dimension,
no margin factor (any factor under 1.0 leaves a long-axis gap — checked
numerically) — the composite fills edge to edge, overhanging the short
axis into pan-space; the refloat center-equality early-return already
prevents refetch churn at rest (proved, not just tested).
Input model (Jeroen: drag breaks click semantics with map objects):
LMB-drag pan REMOVED from the regional window; clicks are
object-reserved. Pan = held WASD/arrows polled in _process (delta- and
zoom-scaled, camera-pans-toward-key convention verified numerically)
plus edge-scroll within 24px of the viewport border; both suppressed
over UI and on OS focus loss; both set _user_adjusted; wheel zoom and
Esc unchanged. Reads RAW physical keycodes deliberately — independent
of the shared D-054 move_* InputMap actions bound to the same keys
(whose occlusion-leak is pre-existing and now ticketed as T-1146).
Pole wall + east-west wrap unchanged, re-driven through the new
inputs; drag tests replaced, not kept.
Smoothed composite (interim pending T-1143): per-cell colors bake into
an n x n Image/ImageTexture (exact existing colorizer incl. overlay +
ice tint) drawn once with LINEAR filtering — GPU bilinear reads as
terrain, the planetary heightmap's own treatment. Crisp per-cell path
preserved behind COMPOSITE_SMOOTH for T-1143 A/B. Rebuild only on
reference-identity change of window/toggle (is_same — verified true
reference equality; value-equal distinct dicts DO rebuild).
Governance: T-1145 amendment paragraph on D-226 T-1124 SS5 (all three
supersessions); pql decisions validate ok.
Suites: window_viewer 74/74, window_geometry 32/32, window_overlay
(new) 16/16; gdlint clean on all six files.

Bounds gate: AtlasDescendGeometry.is_on_texture() — ONE helper feeding
both the reticle guard and the click fall-through (the T-1140 lesson:
the visible affordance always matches the click); half-open
[0,tex_w)x[0,tex_h) boundary pinned at the exact edge. Letterbox
clicks no longer show a reticle or descend.
Fit-and-center: pure fit_window_view() (new atlas_window_geometry.gd)
wired into enter(), the FIRST window arrival, and NOTIFICATION_RESIZED
— gated by a _user_adjusted flag so the fit never fights manual
zoom/pan (flag clears only on a fresh enter). Found-own-bug: RESIZED
can fire mid-_ready() before _canvas exists — null-guarded like the
sibling panels.
Pole wall (Jeroen's ruling): clamp_pan_offset_to_pole_wall() clamps
the WINDOW EDGE, not the center, in screen space from the fitted
transform — Y only; wired into the drag handler and every fit (a
fresh fit can itself need the wall on a tiny body — the
window-taller-than-planet case is handled and tested). Three numeric
hand-traces preceded the code; a first-draft test using GJ380c's huge
radius silently never exercised the clamp — replaced with a synthetic
small radius.
East-west wrap (Jeroen's ruling): canonicalize_district_center() —
posmod column wrap (verified against a live Godot process to match
Rust rem_euclid bit-for-bit), clamped row; district_extent() shares
the exact formula (incl. .max(1)) with the server's
normalize_window_center so echoes and cache keys agree on canonical
form. Canonicalization applies only to the FINAL refetch center — the
edge-crossing decision stays in absolute district space (first-pass
math error caught by hand-trace). Seam-adjacent cache-key sharing
tested. Pan offset itself has no x wall — circumnavigation is
seamless.
Header: body proper_name/body_id ahead of the coordinates (the cheap
half of T-1141, noted in code). Drag-pan verified through the REAL
DistrictScreen-to-viewer chain and pinned by test (no fix needed).
140 tests across three suites, 0 failures; 94 sibling tests no
ripple; gdlint clean (atlas_viewer.gd at the 1000-line cap a second
round — structural extraction flagged for maintenance).
