jpmschweitzer ce90d69ae8 feat(client): T-1153 + T-1152 client half — continuous cursor-anchored zoom ladder, Region-rung orbital entry, click-through retired
The atlas 'regional' screen now opens the LADDER at the canonical orbital
frame (Region granularity, whole body fitted and centered) and wheel zoom
descends continuously — cursor-anchored, unclamped across rungs, with
progressive refinement (held composite keeps drawing, finer rung swaps in
place on arrival; no blank frame, no mode flip). Full-zoom-out resets to
the canonical planetary frame per Jeroen's HARD condition
(is_fully_zoomed_out = extent >= body circumference, not a zoom-value
heuristic). The district_screen nav hop is deleted — D-013 restored:
descent is a zoom gesture, not a nav push. AtlasViewer's heightmap-texture
path is unreachable from nav (code intact; overlay surface deferred, see
report/tickets).

Rung selection: design doc §5's literal formula has NO legal District band
at any real viewport (visual-tolerance band and n=64 coverage ceiling
never overlap — pinned by executable boundary tests at 1600x900);
select_rung() splits it into a coverage ceiling (decides Region) then the
2x visual tolerance (District vs Quarter), documented at the function.
In practice the ladder steps Region -> Quarter directly.

Wire: window_granularity_v2 encoded (omitted at District for byte-compat),
granularity_v2 echoed value keyed + staleness-guarded end to end; Region
clamp mirror replicates the server's bounded halving loop (no closed
form). MIN/MAX_ZOOM widened to [0.0005, 64] — the old 0.5 floor would
have clamped a real body's canonical fit zoom, violating the reset
condition.

Real pre-existing bug fixed in atlas_window_overlay.gd: the draw path used
echoed n as both cell-grid dimension and district extent — only
coincidentally correct at District granularity; Quarter/Region would have
read wrong array offsets. cell_grid_side_for_window() now mirrors the
server's WindowGranularity::cell_grid_side.

Tests: +26 pure-function geometry tests, new 30-test zoom-ladder suite,
extensions across the window cache/request/overlay/delivery suites.
Full suite 3518 green; cold-parse clean.

jpmschweitzerandClaude Fable 5 831625019a fix(ui): T-1142 client — descent bounds gate, fit-and-center, pole wall, east-west wrap, body-name header
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).

jpmschweitzerandClaude Fable 5 4eed3bccb2 fix(ui): latitude-inverse denominator + reticle city-hover gate (PR #187 findings)
Hoshe's blocking find: district_pos_at divided the latitude axis by
tex_h where the server forward map uses ta.h.saturating_sub(1)
(district_profile.rs:1436; ground-truth inverse aliveness_probe.rs:511)
— every off-equator click descended into the wrong district, up to
~20km drift, live-repro'd at 10.2km. Fixed to /(tex_h - 1.0) with the
reference implementation's degenerate-texture guard; verified against
the repro (row 50: old formula recovered 41, fixed recovers 50 exact).
Columns were already correct (longitude wraps — the asymmetry the
docstring documented but the code didn't implement).

Regression tests transcribe the server forward formula (source cited)
and round-trip three off-equator rows — one per hemisphere plus
near-pole — asserting EXACT recovery; a dedicated drift guard is
framed as Tyre's C2 (a client-side twin of a server mapping owns its
own round-trip proof). Root-caused the coverage hole: the old
equator test sampled tex_h*0.5 believing it was the equator pixel —
the true equator is (tex_h-1)*0.5, so the test never verified what it
claimed; corrected with the why documented.

Araminta's find: the descend reticle drew unconditionally on hover —
over a city the marker flared white (city-click signal) while the
reticle+extent label promised descent, though the click correctly
resolved to city data. Extracted _should_draw_descend_reticle() with
the missing _hovered_city.is_empty() clause; three state tests pin
shows-over-map / hides-over-city / hides-when-idle.

test_atlas_descend_entry 32/32; adjacent clusters no ripple; gdlint
clean (atlas_viewer.gd at exactly the 1000-line cap).

jpmschweitzerandClaude Fable 5 9e1e6db614 feat(ui): T-1138 regional map screen — click-through descent, fixed planetary view, windowed composite (D-226 T-1124 SS5)
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.
