jpmschweitzerandClaude Opus 5 fab70edd5a feat(ui): the stipple says WHERE the ground is broken, not just that it is (T-1194)
RimWorld's technique 4, the reference this ticket names, works by CONTRAST: the
Rockies and Appalachians carry dense hatching and the Great Plains carry none.
Ferrath's Global carried an even wash of dots over every landmass instead —
texture present, information absent.

The cause was a constant measured on the wrong rung. RUGGEDNESS_FULL_SCALE_Q = 4
comes from Region ("d4 2.38"), but the elev_q path it gates only ever RUNS at the
orbital rungs, where relief_q is flat and the stipple falls back to it. Ferrath
Global measures a mean 1-cell elev_q gradient of 0.99, so a coherent 4-cell
baseline reaches ~4 and saturates the constant exactly: every land cell read as
fully rugged.

It now normalizes against the canvas's own measured gradient — the same
self-calibrating shape T-1240 gave the hillshade, and for the same reason: one
constant cannot serve rungs whose sample spacing differs by four orders of
magnitude. A contrast curve rides on top, because even unsaturated the linear
reading puts ordinary ground mid-range and paints grain everywhere.

Measured on Global, before -> after: 1,679 -> 1,900 distinct colours, 145.90 ->
147.39 lum spread, and the pale uplands now stipple visibly denser than the
lowlands beside them.

Recorded because it cost two wrong turns: I first guessed saturation, then
talked myself out of it after measuring a 1-CELL gradient (0.99) against a full
scale meant for the 4-CELL baseline, and shipped a contrast curve alone — which
measurably did nothing (1,679 -> 1,698), because a curve cannot separate values
already clamped to 1.0. The gamma is kept; it does its job now that there is a
range to curve. The elev_q gradient joins relief_q's in the capture readout, so
the next person tuning this can read the number instead of guessing at it.

jpmschweitzerandClaude Opus 5 9b146f9e1f fix(simulation): derive at the octaves a rung can actually reconstruct (T-1240)
Region rendered as fine uniform stucco while District and Quarter, on identical
code, read as terrain. The cause was sampling: `min_wl_m` arrives as an LOD
request and defaults to 0, so every invented octave contributed at every rung.
MIN_WL_BANDS_M was meant to be the floor but is built from the rung's CELL SIZE
(2 x DISTRICT_M), which stopped being the sample spacing at the D-255 extent
inversion — a rung fixes EXTENT now and spacing falls out of the canvas size.
The bands were off by roughly the cell count, and the served path never consulted
them anyway.

The cutoff is now derived from the resolved spacing, which is what this ticket
asked for. Two things had to be measured rather than reasoned to get it right,
and both corrected me.

FIRST: the field was the culprit, not the renderer. I attributed the stucco to
the client stipple painting noise onto a smooth field. Surfacing the terrain
layer's own mean |relief_q gradient| in the capture readout settled it in one
shot: Region 18.24 steps per cell — 144 m of relief between NEIGHBOURING cells —
against District's 0.30 and Quarter's 0.07. The server was sending noise. That
diagnostic ships here for the same reason `plane_variety` did in T-1213: a noisy
field and a renderer inventing noise look identical, and one number separates
them.

SECOND: Nyquist is the wrong threshold. The first version floored at 2 x spacing,
the aliasing limit, and Region barely moved (56.16 -> 59.73 lum spread, gradient
still 18.24) because 2 samples per cycle is unaliased but renders jagged. The
rungs that already worked say what the real bar is: District reconstructs its
finest surviving octave at 34 samples per cycle, Quarter at 135. At 8x, Region
goes to 1.08 gradient and 70.01 spread, and shows ridges and valleys.

THE TRADE, taken deliberately and recorded in the tests: an 8x floor also
truncates the coast warp's 2,048 and 1,024 m octaves at Region, the band T-1160
added for "one coastline at every rung". An earlier test here asserted that band
must survive; it now asserts the opposite. Same reasoning as the relief: a
1,024 m coastline wiggle at 379.3 m per cell is 2.7 samples per cycle, so drawing
it draws noise rather than coastline character — a rung cannot show shape finer
than its own cell. The warp is amplitude-capped sub-pixel on the working grid, so
what is lost is small. If a future pass wants the warp exempt, the fix is a
relief-only floor threaded through derive_at_metres, NOT a lower multiple, which
takes the stucco back.

Global is exempt: its floor would be ~70 km and would truncate the whole warp
band, and it needs none — the orbital derive leaves relief_q flat at 50. District
(3.79 m spacing) and Quarter (0.948 m) floor below every octave in play and
derive byte-identically, which their own test pins.

Cache-safe by construction: the floor is a pure function of (rung, extent,
body_radius), all three already in the step-canvas cache key. 0.4.12 is required
anyway — this changes derived BYTES at Region, so a 0.4.11 entry holds a field
this build would never produce.

jpmschweitzerandClaude Opus 5 6d4c9e92c2 feat(ui): the copse and the rocky outcrop, drawn per cover class (T-1213)
D-258 invariant 2 asks the map to show the minority the orbital summary
suppressed — clearings, marsh, rock, scrub inside a cell that reads "forest" from
space. composition.rs goes to real trouble to invent it, and the conservation
harness measures it: over a District patch on Ferrath the tally is {Barren: 175,
Forest: 16209}, so 1.07% of that ground is exposed rock.

The renderer was averaging it back out. One test, `veg >= Scrub`, at one density
and one strength: Forest, Scrub and both Riparian classes drew the IDENTICAL
mark, and Barren drew none at all. A wood looked like scrub, and bare rock was
invisible by construction — on the rungs whose whole purpose is to show what the
summary hid.

Each class now has its own grammar, differing on the three axes a mark has:
density (how much of the class's ground carries it), strength (how far it moves
the base colour), and lattice (the block size marks are decided on — bigger reads
as a clump, smaller as grain). Rock LIGHTENS where everything else darkens, which
is the point rather than a flourish: bare stone catching the light is the one
cover type brighter than the ground around it, so it separates from vegetation by
sign alone and can never read as "denser plants". It gets its own ScatterField
salt so an outcrop does not preferentially land where a copse already did.

Tuned against captures, not guessed. A first pass gave Forest a 4x4 lattice at
52% density, which produced visibly axis-aligned dark SQUARES — a 4-cell block is
8 screen px at District — and read as an artefact laid over the hillshade. It
also mistook the background for a feature: Forest is 98.9% of this frame, so
marking half of it dark is not "the occasional copse", it is a second colour
layer. Pulled back to grain at a 2x2 lattice, and the occasional thing is now the
thing that catches the eye: the outcrops read as scattered pale clusters of
exposed ground, exactly the "occasional copse/tree/rocky outcropping" that was
missing.

District holds its form through the change (lum p1-p99 74.15, against 74.43
before the cover marks and 13.72 when the rung was flat).

jpmschweitzerandClaude Opus 5 8787ee1844 feat(ui): hillshade the deep rungs — form from light across slope (T-1213)
relief_q now reaches the renderer, and the first pass spent it on brightness:
lighten where the ground is high, darken where it is low. That moved the numbers
(District 13.72 -> 77.01 lum spread) and still looked like moss, because the eye
does not read landform from absolute brightness. It reads it from light falling
ACROSS a gradient — height-shading gives a rise and a fall the same tone, so no
ridge ever reads as a ridge.

So relief drives a proper hillshade: the local gradient of the field dotted with
a light from the upper-left. The light direction is not a free choice; lit from
the lower-right the brain inverts the read and valleys pop out as ridges.

THE SCALE IS MEASURED PER CANVAS, not fixed, and the first attempt at this failed
exactly the way this file already warned a fixed gradient constant would (see
RUGGEDNESS_BASELINE_CELLS: "the same 4-cell delta reads 21.86 at Region and 0.08
at District"). With a constant full-scale of 8:

    Region 81.72 but District 77.01 -> 20.01, Quarter 42.56 -> 16.44

because at District's 3.8 m per cell neighbouring cells barely differ. The
terrain layer now measures each canvas's own mean |gradient| once per rebuild and
the hillshade normalizes against it, so one constant works at every rung.

Ladder (tooling/atlas-flatness, lum p1-p99), flat -> shipped:

    Global    145.69 -> 145.69   unchanged; relief_q is flat 50 at orbital
    Region     33.59 ->  54.30
    District   13.72 ->  74.43
    Quarter    11.01 ->  73.72

District and Quarter now read as terrain — ridgelines, valleys, and the stipple
organised into contour-like bands. Judged by eye on the captures, not by the
metric alone.

Stipple full-scale 25 -> 60. The old value was calibrated against a relief_q that
never arrived, so it was tuned to the elev_q fallback; with the real plane nearly
every land cell earned a mark and Region read as static (17,599 distinct colours,
more than twice Global's, for a quarter of the legibility). Form comes from the
hillshade now; the stipple is grain on top of it.

REGION IS NOT FIXED, and the cause is T-1240 rather than this change. It renders
as fine uniform stucco: a Region cell is 379 m of ground while the relief field's
content sits in the 128-1024 m band, so the field is at or below Nyquist and the
gradient the hillshade reads is aliasing, not slope. min_wl_m defaults to 0 on
the served path, so nothing truncates the octaves Region cannot resolve — which
is precisely what T-1240 proposes to fix. That ticket said the stale cutoff was
"currently inert"; it is now the thing capping Region, and T-1240 is updated
with the measurement.

Three tests, on direction rather than magnitude so tuning does not rewrite them:
a hill's west flank lit and east flank shadowed, a uniform field shading nothing,
and the canvas edge not drawing a rim. That last one is a bug this nearly
shipped: `_l8_value` returns 0 out of bounds and 0 on relief_q means MAXIMUM
HOLLOW, so sampling off-canvas posts a full-scale false gradient all the way
round the frame. The sample position is clamped instead.

jpmschweitzerandClaude Opus 5 3ec35b87c8 fix(client): the deep rungs were flat because relief_q fell off the wire (T-1213)
`relief_q` is the one field with signal below District — elev_q's 80 m steps
quantise sub-district detail away, which is precisely why relief_q was invented.
The server has encoded it since 5eb394b36 and the terrain layer has asked for it
by name ever since. step_canvas_protocol.gd's decode dictionary never listed the
key, so `canvas.get("relief_q")` was always null and the plane arrived nowhere.
The server half of that change landed; the protocol half did not.

That is the whole reason Region and below rendered as a flat wash. Measured plane
variety at District before the fix:

    {morphology: 1, elev_q: 11, relief_q: 0, moisture_q: 25, vegetation: 3}

A 0 there means ABSENT, not constant — a distinction the capture could not make
until this commit adds it, and the reason two earlier sessions read the flatness
as a missing generator rather than a missing key.

Also spends the field properly. It drove a stipple PROBABILITY only, so a ridge
and a plain differed in dot density, which at one pixel per cell reads as noise;
and `_ruggedness()` took absf(relief_q - 50), discarding the sign the server
deliberately preserved ("a hollow and a rise are different ground... the reverse
is not recoverable"). Relief now shades continuously and signed — rises lighten,
hollows darken — UNDER the stipple rather than instead of it. Ruggedness
(unsigned) and elevation (signed) are different questions and both are worth
asking.

Ladder, before -> after (tooling/atlas-flatness, lum p1-p99):

    Global    145.69 -> 145.69   unchanged, correct: relief_q is flat 50 at
                                 orbital rungs by construction
    Region     33.59 ->  71.01   2.1x
    District   13.72 ->  77.01   5.6x
    Quarter    11.01 ->  42.56   3.9x

Structure retention Global->Quarter: 7.6% -> 29%.

NOT finished, and the ticket says so: Region now reads as heavy speckle, because
ruggedness is real data instead of an elev_q-gradient fallback and far more cells
earn a mark than the T-1194 tuning assumed; District reads as soft blobby relief,
form without directionality. Both are grammar/tuning follow-ups on a channel that
finally carries signal.

0.4.9 is a REQUIRED bump. The disk cache stores the DECODED canvas, so every
earlier entry physically lacks the field and would keep rendering flat against a
build that reads it — the first bump in this series where a warm cache is wrong
about CONTENT, not merely stale. tooling/canvas_sources.py gains
step_canvas_protocol.gd for the same reason: it decides which planes exist, the
cache stores its output, and the T-1242 gate would not have flagged this fix
while the registry stopped at ui/.../step_canvas/.

Regression cover: every protocol test passed throughout the weeks the plane was
missing, because each asserted a field it already knew about and none asserted
the SET. There is now a test walking all eight dense planes of EncodedStepCanvas,
verified by disabling the fix and watching it fail by name.

jpmschweitzerandClaude Opus 5 e5224b1a44 chore(meta): 0.4.8 — the T-1242 gate's first false positive, paid not dodged
A test-only edit to composition.rs tripped the canvas-generation gate, which is path-based and cannot tell an assertion fix from a generator change. Bumped rather than excepted: the ruling is that a false positive costs one round of cache misses and a false negative costs a week. Second no-op bump in two days, noted in project.yaml so the rate is visible if it becomes noise.

jpmschweitzerandClaude Opus 5 48fee8a0b6 feat(config): make the canvas-generation/version pairing a gate, not a habit (T-1242)
project.yaml's version is the Atlas disk cache's only invalidation signal, and
nothing enforced that changing canvas GENERATION also moved it. It broke five
times -- 0.4.2 lake_margin_q, 0.4.3 coast_warp_px, 0.4.4 the extent inversion,
0.4.5 the Global sentinel, 0.4.6 one-course-per-river -- each bumped only after
someone noticed a wrong map. The failure is invisible to its author: it needs a
warm cache to reproduce, so a cold checkout looks fine. T-1239 is the last one,
and it took eight days.

tooling/canvas_sources.py is the path registry; tooling/check-canvas-version
rejects a push that touches those paths without moving project.yaml's version
line. Wired into the pre-push hook, `make check-canvas-version`, and, for the
parsing units, `make test-tooling`.

Verified against real history rather than a synthetic branch: run over
4e503c356 -- the commit that actually caused T-1239 -- the gate rejects and names
the three files. Run over the commits that DID bump (bdea71953, 39f0fd8c5, and
T-1239's own fix), it passes.

The registry is globbed, not hand-listed. step_canvas.rs imports ten sibling
modules and those import more, so a traced closure would be stale within a month,
and stale here is silent. It over-includes on purpose: a false positive costs one
bump and one round of cache misses, a false negative costs another week of a
wrong map -- the ticket's own ruling.

Two deliberate calls worth naming. The registry includes ITSELF, which closes the
narrowing hole: remove a path and change that same path in one push, and the gate
still fires because the registry file is in the set. And there is no override
flag -- it would be reached for exactly when someone is certain their change is
harmless, which is the reasoning behind all five regressions.

Version bumped 0.4.6 -> 0.4.7 with NO canvas-generation change: self-inclusion
means adding the registry trips its own rule. Spent rather than special-cased,
because the first exception is how a rule like this dies.

The units cover the property no branch run can show -- that editing project.yaml's
comment block, which quotes old version NUMBERS directly above the field, is not
a bump -- plus a registry-coverage test naming the files each of the five known
regressions touched, so a future narrowing past them fails loudly.

jpmschweitzerandClaude Opus 5 086d9ed56e fix(client): bake the version into the build, so an export can invalidate its cache (T-1241)
current_schema_version() line-scanned res://../project.yaml at runtime. That
resolves to the repo root in a dev run and to nothing in an exported build, so a
shipped game got the "?.?.?" fallback every time. Since that tag is the Atlas
disk cache's ONLY invalidation signal, every exported build stamped and compared
the same sentinel: a canvas cached by one build would be served by every later
build, forever. T-1239 is what that failure looks like once it happens.

loading_screen.gd carried a byte-for-byte copy of the same function, so the
version shown to the player was "?.?.?" in exactly the builds where a version
string is worth showing. Both call sites now share client/scripts/build_version.gd,
which reads application/config/version out of ProjectSettings — a value Godot
bakes into the PCK, identical in the editor and in an export by construction
rather than by luck. No file IO, no fallback branch.

project.yaml stays the source of truth (CLAUDE.md); client/project.godot mirrors
it. A mirror nobody checks would be worse than the bug it replaces -- the old
code failed loudly everywhere, a stale mirror fails silently -- so
tooling/check-client-version compares the two and the pre-push hook runs it
unconditionally. Not gated on "were those files in this push": drift persists on
main once introduced, and gating would let an existing drift ride along.

The test this replaces asserted that current_schema_version() did not return its
fallback, and passed -- in the one environment where the code under test worked.
Three tests now pin the property that actually matters: a real version, sourced
from the baked setting, matching project.yaml.

jpmschweitzerandClaude Opus 5 07ed2a47ab fix(client): the Atlas was replaying a cache from a build that no longer existed (T-1239)
Ferrath's Global map drew no rivers at native resolution: 375 courses arrived
and 0 were drawn. The report suspected the D-261 length cull or the water
truncation. Both were innocent, and so was the renderer.

The client served the canvas from its own disk cache (T-1183). Every payload
for GJ820Bc predated T-1237 (4e503c356), which replaced one-course-per-D8-hop
with one-course-per-river -- so the map was drawing 375 hop fragments whose
longest run was 106 km, all of them under D-261's read-as-a-line floor. Same
build, same scenario, same 3440x1440, cache the only difference:

  stale   courses=375  runs=180  longest=6.0px  (~106 km)   drawn=0
  cold    courses=73   runs=23   longest=93.2px (~1,644 km) drawn=18

It looked resolution-dependent because it wasn't a resolution at all: 960x540
resolves to an 814x407 canvas, a key never cached, so it missed and re-derived
correctly. 3440x1440 resolves to 1080x540, which had an entry from 2026-08-06.
During the stale capture the server logged no course production whatsoever --
the canvas never came from it.

The cache's only invalidation signal is project.yaml's version, and 4e503c356
changed how canvases are generated without touching it, so hop-shaped entries
stayed valid. All 13 stale entries are stamped 0.4.5. 0.4.6 forces them to miss;
that, not clearing a local directory, is what repairs a player's Atlas.

The harness let this hide for eight days, in two ways now fixed. It ran against
the developer's persistent user:// cache, so a capture could render a canvas
built by a build that no longer existed -- and any golden shot in that window
silently inherited it; user:// is now isolated per run. And it sent server
stderr to /dev/null via an already-unlinked mktemp file, so no tracing from a
capture was ever reachable; the log now lives at .cache/visual-server.log.

The capture readout gained runs= and longest= between courses= and drawn=,
because "375 arrived, 0 drawn" is not one fact but three stages, and telling
them apart is what turned a guess between two suspects into a measurement.

Follow-ups filed: T-1241 (current_schema_version() returns its ?.?.? fallback in
an exported build, so a shipped game never invalidates on version at all) and
T-1242 (nothing enforces the generation-change/version-bump pairing -- this is
the fourth bump forced after the fact).

jpmschweitzerandClaude Opus 5 43a267439b feat(client): ScatterField — reusable seeded scatter for client-side paint
Extracted from the T-1194 stipple, which was the first of a family: graffiti
placement, cracks in textures, drifting cloud cover — presentation decisions
that must look the same when the player returns to a place, and which the
simulation has no opinion about and should not be burdened with.

THE LINE IT DRAWS. It answers "how is this drawn", never "what is here". A
cell's biome, a settlement's position, whether a wall exists — those are world
data, derived once by the server and sampled everywhere (D-255(f) mechanism B),
and the player eventually stands on them; inventing those here would put the map
and the ground in disagreement. Stated on the class so the next consumer does
not have to re-derive it: if the answer changes what is THERE it is not a
ScatterField question; if it only changes how it is DRAWN, it is.

Bit-identity with the server's Rust noise is explicitly NOT a requirement
(Jeroen: "a seed is a seed and the functional intended outcome is repetition
here"). Nothing here is compared against a server value or round-tripped
through a save, so the contract is stability across sessions, not agreement
across languages — which is precisely why paint belongs on this side: it buys
visual density with no cross-language determinism burden.

Seeded from GameState.world_seed, so two playthroughs scatter differently and
one playthrough is stable forever.

API: domain() resolves a name to a salt ONCE (the first consumer runs ~700,000
times per canvas rebuild, so the hot calls take an int, never a string);
value/chance/pick/jitter for discrete marks; smooth() for continuous fields
like cloud cover; an optional time axis for animation. Domains keep consumers
uncorrelated — without them graffiti and cracks at the same wall coordinate
would mark identical spots and read as one artefact.

The tests pin the CONTRACT, not the numbers — freezing outputs would make any
future improvement to the mixer a breaking change for no gain. They caught a
real defect immediately: (-x, -y) collided with (x, y), because negated
coordinates produce negated products and the sign-bit mask folded the pair
together, mirroring every mark west and south of the origin onto its north-east
counterpart. Not an edge case — the descent ladder's own anchor sits at
y = -5,675,959. Fixed by zigzag-encoding coordinates before mixing.

1853 client tests, 0 failed (15 new). Global capture re-verified unchanged
after migrating the stipple onto the service.

jpmschweitzerandClaude Opus 5 5eb394b36f feat(simulation): relief_q — a local relief signal the deep rungs can resolve (T-1213)
The District and Quarter rungs rendered as flat colour, and the cause was not
the biome work everyone assumed. Measured on Ferrath through the production
canvas builder: at District the mean |elev_q delta| between neighbouring
gridunits is 0.02, and NOT ONE PAIR in a 1290x540 frame differs by 2.

elev_q spans 0-100 across the body's whole 8 km elevation range, so ONE STEP IS
80 METRES. A District canvas covers 2,048 m of ground, where the rolling relief
a walker navigates by is metres to tens of metres -- a fraction of a single
step. The sub-district detail IS generated (invent_primitives' scatter and
relief bands compute it) and then rounded away. Confirmed by running the
diagnostic with the octave cutoff disabled: still 0.02.

relief_q carries that same invented fine component against a scale chosen to
resolve it: 0-100 about a flat 50, RELIEF_FULL_SCALE_M = 400 m either side, so
8 m per step -- ten times finer than elev_q. elev_q keeps its body-absolute
meaning and the Atlas legend stays true.

Measured effect, elev_q vs relief_q (distinct values / mean 4-cell delta):

  Region     49 / 2.38   ->   101 / 21.86
  District   10 / 0.08   ->    35 / 0.35
  Quarter     8 / 0.02   ->    19 / 0.06

FIXED metre scale, never per-canvas normalization: the value for a piece of
ground must not depend on what else is in frame, or the same hillside changes
tone as the viewer pans. And it excludes elev_pct deliberately -- this is the
departure from the surrounding land, not height above sea level; including the
base would re-introduce the body-scale dominance that makes elev_q unusable
down here.

50 at the orbital rungs, which skip invent_primitives by design. Nothing is
lost: Global and Region still have varied elev_q (101 and 49 distinct values),
and the client takes whichever field carries signal via a max, with no
rung-name branching.

The client's ruggedness driver changes with it. It was an elev_q GRADIENT,
which cannot work across rungs -- the same 4-cell delta reads 21.86 at Region
and 0.08 at District, so any single full-scale constant either saturates one or
vanishes on the other. relief_q states relief outright, so |relief_q - 50| is
the answer directly and a fixed metre scale is immune to that by construction.

An absent plane reads FLAT, not zero -- 0 on this field means maximum relief
BELOW flat, so a payload without it would have stippled the entire map. That is
reachable: the field is #[serde(default)] so old-shape payloads decode. Two
colorize tests whose fixtures predate the plane caught it.

2004 server tests, 1838 client tests, 0 failed. clippy clean.

jpmschweitzerandClaude Opus 5 566b566519 feat(ui): relief and vegetation texture over the terrain hue (T-1194)
RimWorld technique 4 from the reference map: texture as data, not decoration.

WHY IT WAS FLAT. The base layer reads hue from morphology and lightness from
elev_q. Below Global, morphology resolves to exactly ONE zone per canvas, so
the frame became a single colour whose only variation was a lightness ramp too
subtle to see. Measured on Ferrath at Region: 1 morphology zone, but 49
distinct elev_q values. The information was already on the wire and arriving —
the renderer was discarding it by expressing it in lightness alone.

TWO MARKS, NOT ONE SLIDER — the ticket's design question (b), settled by
looking at the reference rather than reasoning about it:
  - RELIEF stipple: fine, dense, darker, keyed to RUGGEDNESS not height. The
    reference's high flat plains carry none while its ranges are dense with it,
    so the driver is the local elev_q gradient; a high plateau stays clean.
  - VEGETATION blotch: coarser, softer, marked on a half-frequency lattice so
    it reads as patches rather than a second speckle at the same pitch.

Inline in the existing per-cell loop (question (a)) and always-on, base layer
only (question (c)). The TMP/MST/VEG toggles are ANALYTIC reads — stippling a
temperature ramp would corrupt the quantity being read.

THE BASELINE IS MEASURED, NOT GUESSED, and the first attempt got it wrong: a
1-cell ruggedness delta samples mostly quantization noise, reads
near-identically everywhere, and rendered as uniform static over flat green —
grain, not structure. The gradient saturates by about 4 cells (Region: d1 1.40,
d4 2.38, d8 2.41, d16 2.51), so the baseline is 4 and the full scale 4.
Verified by capture at native resolution: on Global the stipple now
concentrates on rugged ground and leaves plains clean.

WATER TAKES NEITHER MARK, and gets a flat tone. An earlier version excluded
Lake alone and stippled the entire ocean — the one surface with no relief to
express. Both open-water zones are excluded now.

The ocean also stops shading by elev_q, which is the same argument T-1188
already made for lakes and never applied here: elev_q on a water cell is the
bedrock UNDER the water, not the surface, so shading the sea by it paints
seabed relief nobody can see. Near a coast that bedrock rises steeply and
quantizes hard, which is exactly where it showed — a pale, pixellated, broken
fringe hugging every shore (Jeroen, on the capture). One tone for the sea reads
as water and lets the coastline be the edge.

D-255(e)-legal throughout: texture-space dithering of already-derived per-cell
values, decided per server cell by a hash of its own coordinates and values —
no sample invented between cells, identical on cache hit and miss.

Two colorize tests updated: both asserted the old ocean shading incidentally
while testing zero-fill/no-crash. Property under test unchanged.

jpmschweitzerandClaude Opus 5 8eb5cb9ff7 feat(ui): the Atlas ladder bottoms out at Quarter (D-255, T-1213)
Quarter becomes the deepest navigable rung. Block and Chunk leave the ladder.

The rule, from the amendment: the deepest Atlas rung is the one at which a
screen pixel shows one subtile. At the uniform 2x2 px display ratio a
3440x1440 window gives 540 gridunits on the short axis, so Quarter's 512 m
extent draws 0.948 m per gridunit -- about one voxel per gridunit and one
0.5 m subtile per pixel. Block (0.237) and Chunk (0.119) magnify beneath the
finest datum that can exist, and measured as exactly that on Ferrath: one
morphology zone, one vegetation class, an unbroken colour field. They were not
missing a feature; there was nothing left to show them.

CHUNK ITSELF IS UNTOUCHED. It remains D-243's 64 m stream/derive unit and is
where Phase 5 derives first-person walkable content -- D-012's
load-around-the-player is expressed in chunks. Block remains the 128 m
generator planning unit. Both keep their enum variants, their extent_m answers
and their wire vocabulary. What was retired is the claim that a MAP of one is
worth looking at.

DEEP_RUNGS moved with the floor, and this is the part worth reading twice. It
is a mandatory D-255(d) hardening: a per-body retention cap bounding how much
ground an exhaustive pan can hold resident at fine spacing. Left as
[Block, Chunk] it would have guarded rungs no client can request -- dead code
-- while the accumulation gap silently re-opened under Quarter, now the finest
navigable rung at ~0.95 m per gridunit. It is now [District, Quarter]. A
control that names its targets by rung has to follow the ladder when the
ladder moves.

Six tests pinned the old floor and were updated rather than deleted, since
each was protecting a real property: the clamp tests now clamp at Quarter, and
the disk-cache tests use Region for "shallow" (District is capped now) and
Quarter for "deep". One new test pins the distinction the change turns on --
the retired rungs are absent from RUNG_LADDER but still present in
RUNG_EXTENT_M, because viewability was retired, not vocabulary.

Also removes the four capture scenarios for the retired rungs, including the
two blank goldens that had been passing against blank captures.

1838 client tests, 0 failed. Server clippy clean, step_canvas suite green.

jpmschweitzerandClaude Opus 5 49812e3127 test(client): the chaining test outlived the chaining (T-1237)
4e503c356 deleted the client's _chain_runs() when the join moved to the
server, but left the test that pinned it. It asserted that three end-to-end
edges chain into one river, which is now precisely what must NOT happen, so
the gdUnit4 suite went red on main. Caught by the push gate; the parse sweep
I did run cannot see a behavioural assertion.

Replaced with the two properties that actually hold now, rather than dropped:

- A river's length is measured WHOLE. One course of four collinear points,
  each 1,500 m segment 5.9 px and under the 15 px floor, total 17.6 px and
  over it. That is the invariant the old test was really protecting — long
  rivers must not vanish because their pieces are individually small — and it
  survives the move to the server.

- Separate courses meeting end-to-end are NOT rejoined. This is the deleted
  chaining's headstone. Water splits a course, and D-261 is explicit that a
  river crossing a lake is two visible strokes, so a client that helpfully
  reconnected them would draw a line across the lake. Three touching
  sub-threshold courses must all be culled; a resurrected chaining pass would
  report one.

jpmschweitzerandClaude Opus 5 c91096a3c9 test(client): retire the top-down visual suite, aim the Atlas ladder at land
The visual gate had stopped measuring anything: 30 of 32 scenarios
failed, and the two that passed were the worst result of the lot.

Deleted the 15 top-down scenarios (fog, HUD, dialogue, NPC, minimap,
cursor) and their goldens. They all failed at a near-uniform ~12%, and
that uniformity across unrelated scenes is one global cause -- the
ultrawide UI stretch moved every element. They cover the renderer the
cascade freezes until Phase 5, which will need its own tests anyway, so
re-baselining would only have blessed a deprecated layer nobody is
reviewing. Jeroen's call.

The remaining problem was the goldens that PASSED. atlas_GJ338Bd_Block
and atlas_GJ445c-m1_Chunk matched at 0.0% because capture and golden
were both blank -- the same "goldens have been measuring nothing" trap
e024cfb3f caught at Global, still live at the bottom of the ladder. The
cause is that every below-Global golden descends at jump_to(ZERO), and
world-metre zero is merely the origin of the region grid, not anywhere
chosen. So _setup_atlas_golden_shot now takes an optional world_center
(default ZERO -- existing goldens are untouched), and a new
atlas_GJ820Bc_land_* set walks Region through Chunk at ONE land point,
so the rungs can be read as a descent instead of five unrelated frames.

aliveness_probe prints the placement's world metres alongside its pixel
and survey cell, since that is the coordinate the Atlas actually
navigates in.

Recorded because it will be asked again: the ladder is anchored via a
CityPlacement, but that is a match record -- a pixel, an archetype, an
orientation -- not built geography. No settlement exists anywhere yet
and none is due before T-1207, so the empty deep rungs are the expected
state. What the ladder judges is the nature layer.

jpmschweitzerandClaude Opus 5 4e503c3565 fix(simulation): a river course was one D8 hop, not a river (T-1237)
D-261 asked for contiguous river strokes, and the client got them by
chaining hops back together after the fact. That could not work: each
hop was warped independently, so a shared confluence point arrived as
two points that no longer coincided -- 375 hops rejoined into 260
pieces, and Ferrath's Global map showed scratches rather than
watercourses.

The join belongs before invention, so it now happens on the server.
river_course::build_paths walks the D8 cell graph into whole rivers
from headwater to mouth, edge-drain, or junction with an already-walked
river (including the joint cell, so a tributary visibly meets its
trunk). step_canvas emits one course per river instead of one per cell,
which also drops the per-hop warp and resampling -- a path's shape is
the terrain's, so there is nothing left to invent. It is cheaper too:
one point per river cell rather than three.

The client's _chain_runs() and its endpoint index are deleted. Runs
survive only for the reason D-261 gives them -- water splits a course,
and a river crossing a lake is genuinely two strokes that must not be
rejoined.

Pinned by a real-terrain test on GJ380c rather than a synthetic graph,
because the bug was caught by eye on real terrain: a lake must have an
outflow that runs to sea level, and no such line existed. It asserts
the property the eye was checking -- rivers are long, at least one
reaches the sea, and every path is a contiguous walk.

jpmschweitzerandClaude 474ab90663 feat(ui): rivers as cartographic strokes (D-261, T-1237)
Rivers now appear on the whole-body map for the first time. Five on Ferrath's
Global canvas, drawn as 5 px strokes that stop at the coastline.

Four rules, all client-side over existing server data, computed once on canvas
adoption rather than per draw:

  - fixed 5 px screen-space stroke at every rung
  - contiguous geometry through the river's own cells
  - never drawn over water — ocean and lake end a run
  - culled below 15 px of on-screen length (3x the stroke: below that a line
    is a square, not a river)

TWO THINGS THE MEASUREMENT FOUND THAT THE RECORD DID NOT ANTICIPATE.

First, the cull unit was wrong. A server "course" is an EDGE of the river
network — the stretch between two confluences — not a river. Culling per
course culls per segment, so a long river assembled from many short edges
vanishes entirely. Measured on Ferrath Global: 375 courses, 180 surviving the
water clip, and ZERO surviving a per-course cull. Edges are now chained
end-to-end into rivers before the cull is applied, which also delivers the
other half of D-261's "contiguous": per-course contiguity only makes each edge
unbroken; joining is what makes a river read as one line rather than dashes.
After chaining, 5 rivers survive at Global — the "major systems only from
orbit" behaviour the record predicted, arrived at by a different route.

Second, and worse: uses_orbital_derive() still read `Global | Region` while
the client's mirror had said Global-only since 2026-07-26. The D-255 amendment
claims "Region left the orbital derive set... it now takes the full
courses-aware derive". That was implemented against the MIRROR and never
against the authority, so Region kept running envelope-only and carrying no
courses — the exact thing the amendment said it had stopped doing. Both test
suites stayed green for two days because neither compares itself to the other.
Fixed here, with a note on each side pointing at the other, since the two
cannot be cross-checked automatically.

Also removes the two gates that withheld courses from the orbital rung — the
reason the whole-body map had no rivers at all. Whether a course is worth
drawing is measured in screen pixels, which only the client knows, so the
server now supplies geometry at every rung and the client decides.

The capture harness reports "drawn" alongside "courses", because "375 courses
arrived" and "375 rivers are drawn" are different claims and conflating them
is what made an empty map look like a data problem.

Client suite 1836 / 1810 passed / 26 skipped. Server suite green.

jpmschweitzerandClaude 21e263d0a4 feat(ui): stretch the UI to the window aspect — support ultrawide properly
Jeroen on a 3440x1440 panel: 'it does not fit the viewport', then 'widescreen
users are fully supported so we add stretching ui'.

client/project.godot declares a 1920x1080 base viewport with
stretch/mode=canvas_items, and stretch/aspect was unset — which defaults to
'keep'. On a 21:9 display Godot letterboxes the entire 16:9 UI inside it, so
every screen in the game was pillarboxed, not just the Atlas. Measured: the
window came out 2432x1368, exactly 16:9; with aspect=expand it becomes
3440x1368, the full panel width.

Worth being explicit that the Atlas was innocent here. It was filling its
logical viewport correctly the whole time; that viewport was being boxed
inside the monitor. The three genuine Atlas sizing bugs fixed today (the
zeroed extent, the legend-column mismatch, the integer-ratio floor) were all
real and all separate from this.

expand gives every screen more space on a wide display instead of bars, which
is the right default for a UI-heavy game with a HUD and implant panels. The
tradeoff is that layouts must tolerate a variable aspect ratio rather than
assuming 16:9 — accepted deliberately, since widescreen is a supported target.

Verified: full client suite 1833 / 1807 passed / 0 failed, cold-parse clean,
parse sweep clean across 226 scripts.

jpmschweitzerandClaude dac64a8a40 fix(client): the Atlas map scrolled itself off the world
Jeroen: 'it scrolls out of screen automatically.' It did, with no input.

_gui_input only fires while the pointer is over the Control, so
_last_mouse_pos freezes at wherever it was last seen. Leaving the map ALWAYS
means crossing an edge, so the frozen value is always inside the 24px edge
margin — and the viewer went on believing the cursor was held there, panning
forever. Moving the mouse elsewhere could not stop it, because 'elsewhere'
generates no events this Control ever hears.

NOTIFICATION_MOUSE_EXIT now resets to the same (-1,-1) sentinel the field is
born with, making 'pointer is not over the map' and 'pointer has never been
over the map' the same state. Neither should scroll, and there was already a
test asserting the second case — the first had no equivalent.

Considered and rejected: reading get_local_mouse_position() live instead of
caching. It is arguably cleaner, but it cannot be injected in a headless test,
so it would have traded a bug for the inability to prove the fix — and the
existing edge-scroll suite drives _last_mouse_pos directly.

This also explains the drift I had blamed on the capture harness (T-1236):
same defect, and the harness was simply exercising it faithfully.

jpmschweitzerandClaude 144d35d2a5 fix(client): size Global's cell count so the display ratio divides exactly
Jeroen: 'still not filling the screen... maybe we should calculate the depth
that needs to be invented based on the canvas size somehow.' That is the fix.

The old flow picked cells from the viewport, let the SERVER impose Global's
2:1 aspect, then fitted the returned extent into the drawable area with an
INTEGER pixels-per-gridunit ratio. When that extent did not divide the area
evenly, floor() dropped a whole step — and at ratio 2 the only step below is
1, i.e. half size. Worse, because the client fitted an extent it had not
chosen, the result could fill NEITHER axis.

Inverted: global_fill_extent() chooses the cell count FROM the ratio, already
shaped 2:1, so cells * RATIO is the drawn size by construction and lands
exactly on the binding axis. Verified across window shapes — 1920x1080 fills
width, 2560x1080 fills height, 2560x1440 width, 3440x1440 height, 1280x720
width. Exactly one axis fills at every shape, which is the most a 2:1
equirectangular canvas can do in an arbitrary viewport; the other letterboxes.

Global keeps its 2:1 aspect because it is 360 degrees of longitude by 180 of
latitude — the aspect cannot follow the viewport without shearing the map.

Tests pin the invariant directly: 2:1 preserved, never overflowing the
drawable area, and never leaving slack on BOTH axes.

jpmschweitzerandClaude d36d458b74 fix(client): Global drew at half size — request and fit disagreed about the legend
Jeroen: 'that does not fit the viewport'. Correct — Global rendered a real map
into roughly a quarter of the available area.

_letterbox_scale_for() reserves LEGEND_COLUMN_PX before computing the Global
fit, but _request_extent() sized the request against the FULL Control width.
Because that fit is an INTEGER pixels-per-gridunit ratio, the disagreement
does not degrade gracefully: at a 1920-wide window we asked for 960 gridunits
but could only fit floor(1628/960) = 1 px each, so the canvas drew at HALF the
intended scale with room to spare on every side.

The request is now sized to the drawable area, so both sides agree: 814
gridunits at 2 px = 1628 px, plus the 292 px legend column = exactly 1920.
Verified through the capture harness — canvas_scale went 0.5 -> 1.0.

Only Global reserves the column, so only Global adjusts; the fixed rungs are
untouched.

Also corrects the regression test I wrote yesterday, which computed its
expectation from the full viewport and so encoded the bug.

jpmschweitzerandClaude e024cfb3f9 test(client): the Atlas Global goldens have been measuring nothing
Every atlas capture scenario built its body dict without body_radius_km.
Radius is Global's ONLY spacing input (2*pi*R / width), so every Global
golden has been a degenerate block since these scenarios were created — the
map rendered at 0.000 km/gridunit. The fixed rungs were unaffected, since they
derive spacing from the rung's own cell size rather than the body.

That means the "eyeball check against .cache/screenshots baselines"
discipline has been hollow at Global specifically: a baseline that is a solid
rectangle diffs clean against a new solid rectangle. It is how a 2x1 canvas
survived in front of two verification layers.

Adds the real radii to all ten scenarios (Lendel 6238.4, Vethis 6959.3,
Arbour 6711.0, Ferrath 6062.0, Threshold 5503.5), and makes the capture log
course and settlement counts alongside canvas_cells — an empty annotation
layer was previously indistinguishable from a populated one in the log, which
is exactly the signal needed to tell "no rivers" from "rivers not drawn".

Also updates three suites to the corrected Global cache contract: the key now
honours extent (collapsing it meant a resize could never miss), so the shared
_land_global_canvas helper must cache under the extent the viewer will
actually request, and the two make_key tests now assert the real rule —
centre collapsed, extent honoured — instead of the retired sentinel.

jpmschweitzerandClaude bdea719530 fix(simulation): Global was a 2x1 canvas — a sentinel outlived the extent inversion
Jeroen's Global map has been two coloured blocks all along. Not missing
hydrology, not a missing layer: serve_step_canvas_request zeroed Global's wire
extent, so every request arrived downstream as (0,0), clamped to (1,1), and
resolved to a 2x1 canvas.

That sentinel was correct when Global's size came from the body's region grid
and the client's extent field was meaningless. The D-255 extent inversion made
Global viewport-sized and this line silently outlived it. The commit titled
"size the Global rung to the viewport" was therefore correct and completely
unreachable — its tests passed by calling resolve_canvas_extent directly
rather than through the serve path, i.e. they tested the function that changed
instead of the path the data takes.

Two more places carried the same dead premise, both meaning the first canvas
ever built answered every later request and a resize could never take effect:

  - GlobalTierCache keyed on body id alone. Now treats a size mismatch as a
    miss, so the re-derive replaces it. Deliberately still ONE entry per body
    rather than one per size: keying by size would make a tier that never
    evicts accumulate an entry per viewport a player has ever used.
  - The client's make_key collapsed Global's extent to a sentinel. Centre
    stays collapsed — Global's canvas really is whole-body and origin-anchored
    — but extent is now part of the key.

project.yaml 0.4.5 forces the 2x1 canvases already on disk to miss.

Verified through the capture harness, not by reasoning: server probe shows
req=(960,540) radius=6238.4 resolved=960x480, and Ferrath's Global now renders
continents, oceans, inland lakes and polar ice where it previously rendered
one solid rectangle.

jpmschweitzerandClaude 791600dd24 test(client): skip the 3D character compositor suite while 3D is not in play
Jeroen's call during the Phase-4 Atlas work: nothing in this suite's subject
is being changed, and it is by a wide margin the most expensive thing in the
client suite. Client run drops from 135s to 96s — 29% — from this one file.

The numbers, measured across all 86 suites:
  this suite     50.0s /   26 tests  (~1.9s each)  -> 37% of the whole run
  all 86 suites 127.1s / 1830 tests
  the other 78   ~33s  / 1804 tests
Every test instantiates a fresh CharacterVisual Node3D and loads the skeleton
.glb plus body and skin-tone assets, so the cost is asset loading per test,
not assertion count. The rest of the suite is close to free.

Used gdUnit4's own suite-skip (__is_skipped) rather than a hardcoded pass, as
requested but one level more honest: a test that returns success without
exercising anything reports as COVERAGE. It inflates the pass count and reads,
to anyone scanning a summary, exactly like a suite that ran and was fine.
The skip reports these 26 as SKIPPED in the statistics — and run-godot now
parses that field and excludes it from passed — so the omission stays visible
in every run rather than being laundered into a green number. It also
short-circuits before the test bodies, so the 50s is genuinely reclaimed
rather than merely hidden.

No test was modified. Deleting the _init() restores the suite exactly as it
was, and the comment says so, along with when to do it (Phase 5 player
rendering at the latest) and the better fix to prefer then — sharing the
compositor instead of rebuilding it per test.

jpmschweitzerandClaude a005e48405 feat(config): parse sweep — verify every project script parses, not just the startup path
godot-cold-parse only ever sees scripts on the STARTUP path: autoloads and
the main scene chain. That is the correct scope for the job it was built for
(Sprint 36's `Could not find base class "MetaScreen"`, a registration-ORDER
bug), but it is far narrower than the name suggests, and most of the codebase
is invisible to it. Verified by deliberately breaking a non-startup UI script
and a test file in turn: cold-parse reported "clean", exit 0, for both.

That is the second half of today's false green. A parse error in
test_step_canvas_annotation_layer.gd survived cold-parse AND survived
gdUnit4, which reports the suites that DID load as a clean pass. Two gates,
one blind spot: neither verified that a file it never opened was openable.

godot-parse-sweep opens every .gd in the project (226 today, addons and
.godot excluded) and fails on any that will not parse.

The split between the two halves is forced, not stylistic. No Godot API
reports GDScript parse failure reliably:

  - ResourceLoader.load(path, "GDScript", CACHE_MODE_IGNORE) SEGFAULTS the
    engine on a script that fails to parse — it dies on exactly the input the
    tool exists to find.
  - GDScript.new() + source_code + reload() returns a clean error code but
    detaches the script from its resource_path, so class_name, preload() and
    relative extends stop resolving: it reported 150 of 226 healthy scripts
    as broken.
  - Plain ResourceLoader.load() neither crashes nor false-positives, but
    returns a NON-null object for a broken script, so its return value is
    useless.

The engine's own stderr is the only honest signal. So the GDScript half just
opens files and makes no verdict; the wrapper scrapes the diagnosis. The
wrapper also refuses to pass unless the sweep reported completion, so a
future break in the walk cannot itself become a false green.

Unlike cold-parse, "Cannot infer the type" is NOT filtered. That filter is
precisely why cold-parse stayed silent about the file below.

First run found a real one: client/tests/util/scene_helper.gd has not parsed
since 2026-02-25 — five months — because `func(a := null, ...)` cannot infer
a type from null. Fixed with explicit `: Variant` params. Blast radius is
zero (the helper has no importers, so nothing else was taken out with it),
but it went unseen by two gates for five months, which is the point.

Full suite green at 3660.

jpmschweitzerandClaude b2ef73256a fix(config): run-godot reported a suite that never ran as a pass
Found by walking into it. test_step_canvas_annotation_layer.gd had a parse
error from an earlier edit in this session, so gdUnit4 could not load it and
ran the other suites instead. The harness printed 3610 passed / 0 failed and
exit 0. Fifty tests had not run for hours and nothing said so — the full
suite reports 3660 with the file repaired, and that difference was invisible.

Two states are now hard harness failures rather than test results:

  load_error — a suite failed to LOAD. Any pass count excludes it, so a green
  number is a lie. The hint names the offending file.

  no_tests  — zero tests executed. A run that executes nothing can never be
  a pass; previously a mistyped --filter printed "Tests passed".

Both add a "harness_error" field to the summary JSON and exit 2. The exit
code cannot inherit gdUnit4's, which returns 0 in both states — that is
precisely why they were invisible.

Verified by injecting each failure rather than by reasoning about it. The
load_error guard was checked in the case that actually matters: one broken
file among many, where total stays large and failed stays zero. That run now
reports 3610/0 WITH harness_error and exits 2, where before it was
indistinguishable from success.

Also repairs the file itself: a missed set_frame() argument (the parse error),
and a cell-placement test still asserting pre-inversion spacing. Rewritten to
assert the invariant that survives the extent inversion, the viewport aspect
ratio and panning — half the SHORT axis is half a rung cell — instead of a
literal. Two things it deliberately does not assert, both of which the
previous version got wrong: "the corner is half a district away" holds only
on a square canvas, and the canvas is one district WIDE without sitting ON a
district. It is a free-floating window centred wherever the player panned;
zoom is stepped, pan is continuous. A rung names a scale, not a cell you are
inside. A second test pins that with a deliberately unaligned world centre,
so a future change that snaps the canvas to the rung lattice — making pan
step instead of slide — fails here.

jpmschweitzerandClaude 1c45cd2ec8 fix(client): Global rung derived its canvas from a pre-layout viewport
Eyeballed on Lendel: the Atlas opened on a Global map that was literally two
cells — one green, one blue — stretched across the window, reporting
19,598.512 km/gridunit, which is exactly half the body's circumference.

Two bugs, both of which the D-255 extent inversion turned from harmless into
fatal.

enter() fires its first request BEFORE this Control is laid out, and a
not-yet-laid-out size is not always exactly Vector2.ZERO — a few stray pixels
sailed past the `== Vector2.ZERO` guard, so the viewer asked for a 2x2
gridunit canvas and the server's 2:1 fit floored it to 2x1. That never
mattered while Global discarded the requested extent and took its cell counts
from the body's region grid; the moment the request became the canvas size, a
transient layout artefact became the map. Any viewport below a plausible
panel size is now treated as not-laid-out.

And Global was excluded from the refetch settle entirely, so a canvas born at
the wrong size could never heal however the window was resized. That
exclusion was correct when no viewport could change Global's extent. Global
now takes the SIZE refit like every other rung, but still never the pan
re-float — its canvas is whole-body and origin-anchored, and the server
ignores `center` for it.

Both have regression tests. The second asserts on _world_center rather than
_view_offset, because _recompute_canvas_transform() legitimately re-centres
the offset on any canvas adoption and would have made the test pass for the
wrong reason.

Worth noting for the class: no test written today could have caught this.
Every one supplies an explicit viewport. The bug lived entirely in the gap
between "scene loads" and "layout completes" — a seam a live launch
exercises and a unit test does not.

Also stages governance/README.md's pql-maintained record index (D-258).

jpmschweitzerandClaude 9c8fcc2f95 feat(client): size the Global rung to the viewport, not the region grid
Global took its cell counts from `global_cell_counts()` — one gridunit per
region — and discarded the requested extent entirely. On GJ380c that produced
a 191x95 canvas built from a heightmap stored at 512x256: roughly seven times
the available cells thrown away before anything was drawn. The count also
shrank as REGION_M grew, so tuning the scale ladder silently degraded the
opener, which is why the top of the ladder got worse rather than better as
the ladder itself was refined.

Global now fits the largest 2:1 canvas inside the requested extent. It cannot
take its ASPECT from the viewport — the canvas is equirectangular whole-body,
360 degrees of longitude by 180 of latitude, and must stay 2:1 or the cells
stop being square and the map shears — so the existing letterbox absorbs the
remainder. A hostile extent is still clamped; sizing to the request is not
trusting the request.

Global also joins the deep display ratio, making the band uniform. At 5 px
per gridunit a 1920 px window asked for 384 cells across a body whose
heightmap holds 512x256 — discarding stored detail to save work already done.
At 2 px it asks for 960, which is heightmap-native: nothing thrown away,
nothing invented, and the same screen area filled either way.

A body with no radius is not a sphere (asteroid belt, oort cloud) and has no
equirectangular surface to fit. Those degrade to the region grid — a visibly
degenerate 1x1 canvas — rather than a plausible-looking lie at whatever size
the viewport happened to ask for.

project.yaml 0.4.3 -> 0.4.4 invalidates the persisted step-canvas disk cache.
District/Quarter/Block/Chunk kept identical 960x540 cell counts through the
extent inversion, so their cache keys are byte-identical while a District
canvas now covers 3.6 km of ground instead of 1,966 km — a warm cache would
silently serve pre-inversion canvases.

Global still rides the orbital derive, so it carries no courses yet; that is
the next step and is deliberately separate, being a cost question over the
whole body rather than a sizing one.

jpmschweitzerandClaude 0a0419abcc feat(client): invert the Atlas rung relation — rung sets extent, not spacing
A rung used to fix the gridunit SPACING, with the canvas extent falling out
of spacing x cell count. That is why the top of the ladder was unusable: at
REGION_M spacing a viewport-sized canvas spanned ~251,658 km — six times
around a rocky body — so the Region rung capped to the body and redrew the
Global picture pixel-for-pixel. "Global and region look the same" was not a
rendering bug; it was this relation, stated in metres.

Inverted: a rung fixes the EXTENT and the spacing falls out of the canvas
size. The shorter viewport axis spans exactly one cell of the rung's level,
so a widescreen window shows more ground on the long axis rather than less
on the short one. Every rung now shows the ground its name promises —
Region 262x466 km, District 4.1x7.3 km — and the canvas cell count is
viewport-driven and identical at every rung, so derive cost no longer varies
with depth and resize is free.

Consequences that fell out of the inversion rather than being chosen:

- Region leaves the orbital derive set. It was envelope-only because at
  251,658 km nothing finer made sense; at 262 km it is a genuine provincial
  map and takes the full courses-aware derive. Region having no rivers at
  all was much of why the top of the ladder read flat. It also joins the
  deep display ratio for the same reason.
- The S2 station-spacing floor is deleted, not retuned. It guarded an
  O(1/spacing) blowup that the inversion makes structurally impossible (the
  canvas cell count is now constant across rungs, so stations-per-course is
  bounded however deep you scroll). Kept, it would do active harm in the
  opposite direction: a 2,048 m pitch across a 3.6 km District canvas places
  two stations and draws every river as a straight line. Station placement
  gets its own generator pass.
- cap_extent_to_body is superseded and now a documented no-op. A canvas can
  no longer over-request a body by construction. The residual question —
  whether a rung's cell exceeds the whole body — is liveness, not capping,
  and is_rung_live_on_body() answers it by omitting the rung. Empirically it
  never fires on inhabited content: all six rungs are live on all 271
  populated bodies with a radius.
- snap_to_gridunit no longer truncates its multiplier to int. Post-inversion
  the deep rungs run sub-metre (Chunk ~0.12 m at a 1080 px short axis), where
  int(spacing) floors to zero and would collapse every request centre onto
  the origin.

Both sides derive spacing from the same three inputs (rung, echoed cell
extent, body radius) rather than one telling the other, so there is nothing
to keep in sync beyond the constant table itself. Body radius already
reaches the viewer via enter(); no wire change.

jpmschweitzerandClaude 36482de5d6 fix(ui): Atlas fetch readout, and one settle timer for resize and pan
Two viewer fixes from the same pair session; they share
step_canvas_viewer.gd so they land together.

FETCH READOUT. A cold derive takes seconds and the map gave no honest
sign of it. Root cause found while building the replacement: a Control
paints its own _draw() BEFORE its children, so everything the viewer
drew itself — the old DERIVING TERRAIN label AND the pending wash —
was painted UNDER the terrain canvas, visible only when no texture
existed at all, i.e. never in the slow-fetch case they existed for.
That has been the state since the stepped viewer shipped. The readout
now lives in its own overlay node added after the canvas: a centered
implant-idiom panel, DOWNLOADING MAP DATA, indeterminate sweep, 250 ms
grace so cache hits never flash it, held canvas still drawing beneath.
Indeterminate by design — the server reports no derive sub-steps, and
a progress fraction we cannot source would be invented.

ONE SETTLE TIMER, THREE TRIGGERS. The viewer never re-requested a
canvas on resize, so one derived for a smaller window letterboxed
forever in a bigger one — the map not filling the frame. And the
pan-edge refetch fired from inside the per-frame pan loop the instant
its threshold was crossed, so a held edge-scroll issued a fresh
request AND snapped the view on every frame past it. Both are the same
event: the user is still moving. A shared one-shot timer now collapses
them into a single request at the resting state, with a hard pan
threshold that still fires immediately when the canvas edge is about
to enter view (waiting there would show empty background), and
drifting back inside the soft threshold cancels the pending request.
Resize reaches this Control identically whether the OS window or a
diegetic in-implant parent changed, so both sources are covered.

Two new tests pin the soft path (schedules, does not refloat or snap)
and its cancellation; the pre-existing threshold test was verified to
still discriminate — its drift trips the new hard threshold — rather
than passing vacuously.

jpmschweitzerandClaude ae03ea2de7 perf(ui): Atlas deep rungs draw one gridunit per 2x2 px block
DISPLAY_RATIO_DEEP 1.0 -> 2.0, so a viewport-fit request at District/
Quarter/Block/Chunk asks for ~4x fewer gridunits (1920x1080: ~2.07M
cells -> ~518K) and the server-side derive cost falls with it. Texel-
exactness is preserved — the ratio stays a whole number of screen px
per gridunit, so every source texel still lands on whole pixels; only
the block size changes. Non-integer ratios are not an option here:
they reintroduce exactly the sub-pixel blur D-255's texel-exactness
exists to prevent.

Judged live by Jeroen against the 1x1 build (pair session): the deep
rungs read as crisp larger pixels rather than blur, and the speedup is
substantial. Looks were the gate.

Both transport tests that pinned the old literal now assert the
RELATIONSHIP instead — deep rungs share the constant, viewport-fit
divides by it — plus a new guard that the ratio stays whole, so the
value remains tunable without editing tests that are not about it.

The legend's reposition() now derives its Y from the header panel's
MEASURED bottom plus a named 12px gap (new accessors on the viewer;
deferred recompute so it reads settled layout, refreshed on header

header's real 77px bottom, fusing the panels. Pixel-proven at the

goldens regenerated at the DOCUMENTED 960x540 (the 1280x720 rider was
my own CLI flag, not a config; PIL-verified) with two-run byte
stability. Two structural tests pin the header/legend relationship
(T-1192 precedent), proven failing-first against the old constant
(-17.0px reported), and the legacy test that pinned the literal 60.0
now asserts the derived relationship so it cannot re-enforce drift.

jpmschweitzerandClaude Fable 5 41144f317f fix(ui): Atlas header gets its implant panel scrim — legible on any terrain (T-1197)
Root cause was not the suspected fade race — no animation exists
anywhere under client/ui/implant (grep-proven, and settle+2 vs
settle+90 captures were byte-identical). _build_screen_header() was
the single ImplantHeader call site in the codebase that added the
header bare instead of through ImplantPanel.add_component(), so its
fixed light-gray text washed out against pale terrain (Quarter upland
scatter, District olive) while reading fine on dark ocean. Wrapped in
an ImplantPanel like every sibling — the theme's panel_bg scrim makes
it legible everywhere. One committed golden (atlas_GJ820Bc_District)
already carried the ghosting baked in, confirming the bug was static;
all 13 goldens regenerated per the header change, two independent
live-server runs byte-identical (T-1157 stability discipline).
Verified live at the original evidence center: header crisp at
settle+2/+30/+90.

_setup_atlas_golden_shot and _run_atlas_matrix rebuilt on the real D-255
surface: nav.push('regional') through AtlasApp's own body-selection tail,
then StepCanvasViewer.jump_to at a fixed center (inventory item 5) — no
shim over the retired continuous-zoom API. is_pending()-aware bounded
settle (mirroring atlas_agent_driver.gd) and view-transform logging
(inventory item 3) wired into both capture paths. The 12 z2_0/z4_0/zfit

fresh --test-mode servers; atlas_shots.json/visual.json re-keyed;

Verification: two consecutive District runs byte-identical, and a

(Global/NEAREST, District/LINEAR) — byte-identical either way, so
capture output does not depend on the shared user://atlas_cache state.

StepCanvasViewer.jump_to seam that reuses _scroll_rung's exact request
tail — same extent cap, same cache keys) and get_current_canvas_summary

AtlasAgentBridge autoload holding the app handle (untyped per the

One commit for two tickets whose changes share the bridge/plugin
plumbing files. T-1169 connects the three dormant feature-name pieces:
atlas_feature_names populated at regen (17,891 rows — 15,190 mountain,
2,701 river — via populate_atlas_feature_names mirroring the city-names
importer; systems.db regenerated, stamp fresh), attach_feature_names
wired into the cascade's Topography block with name pools threaded
DB-free through AnalyzeBody (D-225 pattern) and assignments stored on
Layer1Output/BodyWorldState for future consumers, and a
FeatureNamesRequest/Response read proxy as the bridge's 7th tagged
envelope (D-236 pattern, both SimBridge impls). Client label DRAW is
deliberately NOT here — implementation proved both river and mountain
labels need a wire-carried position (the pool is position-free; course
polylines aren't correlated with the named attractors by construction) —
deferred to T-1195's single design pass. cascade_layer1 golden re-pinned
(additive feature_names field).

T-1159 retires the legacy u32 granularity field fully shadowed by
window_granularity_v2: AtlasLayerRequest.window_granularity,
DistrictWindowLayer.granularity echo, the u32::MAX sentinel, and
resolve_window_granularity are gone server-side; client encode paths and
the caller-less atlas_window_cache legacy key component dropped;
msgpack fixtures regenerated; the T-1150 aliasing regression test now
drives through the surviving enum field. The district_window carrier
itself survives byte-compatible per D-255(c).

jpmschweitzerandClaude Fable 5 686021bee8 fix(ui): PR #207 review round — crop-gated taper, true mitres, hybrid AA (T-1175)
Five findings from the araminta+hoshe round. Tapering now fires only on
a TRUE upstream source: the course's first raw world point is tested
against the canvas's own world bounds (conservative 1m epsilon) —
exact detection because the server crop keeps one point beyond the
window (layer_proxy crop_course_to_window lo = first_in-1, contract
documented), so crop passthroughs draw the old flat full-width cut and
never a false headwater. The averaged-normal joint is replaced by a
real mitre (half_w/cos(theta/2) recovered trig-free via the bisector
normal), clamped by a 2x mitre limit AND 0.45x the shorter adjacent
segment — restoring true perpendicular width at bends (the 29% pinch at
confluences is gone) and preventing the hairpin bowtie; the winding doc
now states the actual bounded guarantee. Antialiasing restored via the
hybrid: only the varying-width taper head draws as a ribbon; the
constant-width ~85% of every course keeps the original antialiased
draw_polyline (byte-identical for untapered courses), split at an
interpolated arc-length point sharing position and width — junction
capture evidence in .cache/screenshots/t1175-fix-round/. Flat-fill
single-element color array. Suite 24 -> 48 tests.

jpmschweitzerandClaude Fable 5 40cf89c3cb feat(ui): river source tapering + width-grammar retune — map fluency pass (T-1175)
The single large polish pass Jeroen requested off the T-1170 captures,
benchmarked against RimWorld's world-map fluency. Courses now draw as
source-tapered ribbons: per-vertex width ramps from a hairline at the
upstream source to full class width over 15% of the course's arc length
(arc-length parameterized, not vertex-indexed, so point density doesn't
change the read), built as one draw_polygon ribbon with mitred joins.
Class width table retuned 0.9/1.4/2.2 -> 0.6/1.2/2.4: a clean ~2x
per-class ladder so a tributary-joins-trunk confluence reads as a join,
trunk held at its visually-proven weight, stream thinner per the
benchmark's thin/consistent/restrained grammar. Opacity untouched
(Araminta's T-1170 ruling stands). Coast-gradient item resolved as
already-correct (the coastal transition zones + elevation lightness
render the shoreline band; capture-verified) — no wire change. Stipple
assessment filed as T-1194. Eight new taper-geometry tests.
