D-258 invariant 2: descending the ladder must reveal COMPOSITION, so a cell
reading "forest" globally contains the clearings, marsh, rock and scrub the
vote suppressed. Below Global it contained nothing: morphology carried NINE
zones at Global and exactly ONE (AlluvialPlain) at every rung under it, and
vegetation collapsed to one class from District down.
WHY THE EXISTING TIERS COULD NOT DO IT. vegetation_invention already perturbs
moisture with a massif band and a texture band — but that pair was built for
cross-rung coherence and is weighted 70/30 specifically so "the texture term
alone can never outweigh the massif term". It is designed NOT to change a
verdict, which is the exact opposite of what composition needs.
And it could not simply be turned up. Measured: 50.2% of the texture field's
amplitude sits in its 32,768 m octave alone, and everything at or below 2,048 m
holds 5.9% of the total. Across a District window only that 5.9% varies, which
after the 30% weight and a ~29-point ceiling swings moisture by +/-0.51 points
against vegetation gates 5-15 points apart. Nothing could ever cross one. That
is the geometric series, not a tuning shortfall — raising the ceiling enough to
matter at District would make the field violent at Region.
So a third tier carries the fine band ALONE, normalized to its own full swing:
quiet where the coarse tiers are loud, loud where they have nothing left to
say. It feeds BOTH classification inputs, because moisture alone would have
left morphology just as flat.
CONSERVATION IS THE BOUND, not weighting (D-258 invariant 3). The field is
zero-mean, so a downsample returns the summary it was added to. Pinned two
ways: a field-level zero-mean test, and a real-terrain test that derives a
District-sized patch and asserts the majority vegetation class survives.
RARE INCLUSIONS, and this was a correction. The smooth term is a gentle sway
around the base, so it can only flip a verdict where the ground already sits
near a gate — which made deep-in-class ground immune, and the conservation test
duly measured a patch that was 100% Forest. A monoculture is the flat map this
ticket exists to fix, one scale down. Jeroen: "maybe a dense forest should
still sometimes produce a clearing or a rocky outcropping." D-258 says CONTAIN,
not border on. A sparse high-contrast term now rides on top — thresholded value
noise so inclusions are connected blobs rather than stray speckled cells. The
same patch now reads 98.9% Forest with 1.1% Barren outcrops.
The moisture half of an inclusion obeys the envelope rule (a world with no
patchiness ceiling grows no glades — caught by the zero-ceiling test, which the
first version failed by putting damp pockets on airless rock); the slope half
does not, because an outcrop is geology and a dead world is exactly where bare
rock should break the surface.
The slope ceiling is 6, not the 15 first written. Measured against the
window-derivation fixtures, base slope_q on ordinary ground is 2-6, so +/-15
did not vary the signal but REPLACED it — one fixture moved 6 -> 19 and two
coastal samples flipped to Wetland on invented slope alone. The morphology
gates are far apart because a cliff coast is a real landform; composition must
let marginal ground fall both ways, never manufacture a fjord on a flood plain.
NOT applied at the orbital rung, which is envelope-only by design and documents
that it never invents slope — pinned by
derive_orbital_at_metres_never_invents_slope, which caught the first version.
Both goldens move in the IMPROVING direction, checked before updating rather
than blind-refreshed:
GJ338Bd moisture 75->85 distinct, slope 28->34 (range 0-50), materials 3->4
GJ244Ad moisture 25->42, slope 15->22, morphology zones 6->7, materials 2->3
Ladder effect (was -> now): Region moisture 25->39; District moisture 3->17 and
vegetation 1->2; Quarter moisture 3->8.
45 server suites green, clippy clean.

A real D-245 gate-shape strengthening, not just a test: the D-256/T-1174
finding proved the believability golden byte-identical under a total
all-North basin_direction collapse — every scalar contrast field is
structurally blind to the one field that regressed. ContrastMetrics
gains land_districts and basin_directions_distinct (both over ALL
districts, no new derive calls — the evidence-backed pick over the
voxel-transect proxy, which washes out at production sample density),
and evaluate_criteria gains 'basin direction variety': pass when
land_districts == 0 (the drained-body guard — an all-ocean body has no
cells that can cast a D8 vote per the aggregator's own exclusion rule,
so a uniform default is legitimate, mirroring the file's existing
nothing-to-vary idiom) or distinct >= 2. Negative test proves the
criterion catches the land-bearing all-North regression; vacuous-pass
test proves the waterworld guard. Golden regenerated and rerun-stable;
both validation bodies (Arbour, Edict) pass at distinct=2.

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).

The Global/Region rungs sampled the heightmap ocean mask raw while every
finer rung samples it at the coast-warped position — a structurally
different coastline at the orbital-to-district seam. Audited on all 267
real body heightmaps at region spacing, coastal band only: 5.01%
land/ocean classification disagreement (2,911 of 58,073 cells), mean
displacement ~6.0 km, max ~18.9 km. Fork taken: APPLY the warp —
derive_orbital_at_metres now runs invent_primitives' steps 1-3 (driver
climate -> coast character -> coast_warp_px) before sampling, still
skipping detail-scatter (its octave ceiling, 32.8 km, is below region
spacing; the WARP's octaves reach 262 km, which is why skipping it was
wrong). Cost measured: ~784 ns/cell added (~15 ms on an Earth-class
Global canvas; low hundreds of ms parallel at the 8.3M-cell ceiling).
The ignored audit test preserves the pre-fix baseline for the record.
Golden re-pinned — region rows only, district/quarter byte-identical.
project.yaml 0.4.2 -> 0.4.3: orbital canvas bytes changed, client disk
caches must miss. Awaiting Araminta's review-seat sign-off per ticket.

region_centre_latitude_deg mapped row 0 to the north pole with lat_frac
clamped [0,1] while the derive core floor-divides equator-anchored signed
world metres — every northern-hemisphere region clamped to +90 (polar
everywhere) and the southern hemisphere read as compressed northern
tropics. Now mirrors the derive core's exact inverse mapping (lat_frac =
centre_y/meridian clamped [-0.5,0.5], lat = -frac*180). The ticket's
in-the-wild datapoint flips as predicted: GJ338Bd region (136,43), old
baseline +13.94N/26.8C -> new -76.06S/10.3C; the 76S district cell now
derives Lake/2.07C/Light glaciation. Goldens regenerated (believability +
window derivation, stable on rerun); two region_profile unit tests
repositioned — their probe coordinates meant different places under the
old convention. step_canvas rung-0 already used the correct signed
convention; layer_proxy's pole-anchored pseudo-grid stays deferred to
T-1181's rung-0 rebuild per D-256(f).

Hoshe finding 1 (live-firing on GJ1c: 2 spill collisions + 1 i==1
collision among 51 Overflow basins): adjacency adjudicated
INSUFFICIENT for the cue — a course's visible anchor is its upstream
cell, so nothing pre-existing belongs to the lake unless wired. The
spill cell (outlet_path[0]) now always gets a real entry: appended
when new, OVERWRITTEN IN PLACE when it collided with an existing river
cell (append would duplicate edge_id; the hydrology solve is the more
authoritative downstream answer for that cell than flat D8
extraction). Interior stop-on-collision stays, now provably safe.
Internal lookup is a dense Vec<Option<usize>>, never iterated (D-010).
Two non-vacuous regression tests prove the cue through build_edges
output; end-to-end on GJ1c all 51 Overflow basins now build a readable
edge (was: one silently missing).
Hoshe finding 2: both doc sites now state the fallback-vs-production
split explicitly (fallback moisture 55: 51/2; production GJ1c moisture
80: 53/53 all-Overflow) — the golden's Endorheic pair is a
fallback-constant artifact, not a fact about GJ1c.
Golden re-regenerated: river_cells 143->192, position-identity diff
purely additive (zero removed, one legitimate in-place overwrite at
the spill-collision cell); attractors/basins/mouths/confluences
byte-identical. Suites: hydrology 26/26, full lib 1943, cascade_golden
1/1, window goldens + believability untouched green.

extend_river_network_with_basin_outlets threads each Overflow basin's
resolved outlet_path into RiverNetwork as real D8 downstream
continuations (spill cell skipped as lake interior; Sea target ends at
RIVER_DOWNSTREAM_MOUTH with a seaward entry, Basin/OpenSpillway at
RIVER_DOWNSTREAM_EDGE_DRAIN); Endorheic basins contribute nothing —
the ruled zero-bit cue is outflow-course PRESENCE (D-227 amendment
(4)): a lake with no outgoing course reads as closed. Additive per
T-1170 Ruling 7b; no wire migration, no new zone, no endorheic bit.
Wired in run_layer1_with_moisture strictly AFTER attractor extraction
so outlet cells never perturb settlement placement (tested). Edge
identity is the existing pack_cell_id (row,col) convention; wiring
determinism proven by three independent double-solve byte-identity
tests. 13 new tests across hydrology_equilibrium and layer1.
Goldens: cascade_layer1.json re-pinned (third deliberate re-pin,
documented in cascade_golden.rs) — river_cells 93->143 on GJ1c,
append-only prefix byte-identical, 51/53 real basins Overflow with
short OpenSpillway stubs (the dominant honest pattern: most basins
spill onto adjacent open ground, not a long channel to sea).
window_derivation_golden and river_course_golden verified structurally
unreachable and unchanged.
Known scope boundary (documented in-code): outlet cells carry
river_class 0 (stream) — outlet-channel classification/meander width
scaled to catchment is a named follow-up, not guessed at here.

Productionizes the T-1177 equilibrium solver: run_layer1 now solves
hydrology once per body (~24ms, mirrors drainage::analyze) and carries
it as TerrainAnalysis.hydrology; run_layer1_with_moisture threads the
real body moisture ceiling (extracted derive_moisture_ceiling_q), with
the T-1177 population-survey default as fallback. The resident rung-0
global tier does not exist yet (T-1181's scope) — hydrology rides
TerrainAnalysis and lands in that tier for free when it is built
(deviation recorded on the ticket).
MorphologyZone::Lake is now sourced from the settled solver at derive
time: a gridunit is Lake when bilinear-sampled filled surface exceeds
bilinear-sampled original elevation at the sample's own (px, py) — the
continuous comparison, so lake edges refine with rung like coastlines;
never a discrete basin-cell projection. The gate sits strictly between
OpenOcean (>= 80) and the old ocean_fraction heuristic (>= 60), which
survives as the derive-fresh fallback when no solve is attached —
byte-identical to pre-T-1184 output in that case. Static
classification, distinct from the sim-state flooded plane; no
endorheic bit (the drains-vs-closed cue is T-1185's outlet-course
presence, per the D-227 amendment (4) sequencing). Zero new wire
bytes.
Acceptance: lake_classification_cache_hit_equals_cache_miss (solve
twice independently, byte-identical zones, non-vacuous Lake hit) plus
hydrology determinism tests. Golden fidelity: the window golden
fixture now builds TerrainAnalysis through the production entry point
(run_layer1_with_moisture, per-body), and a dedicated lake_bowl golden
body pins the hydrology-sourced Lake path (morphology 1 at
ocean_fraction_q 0 — provably not the heuristic); the 108 pre-existing
golden rows are byte-identical (pure append). believability.json moved
by one lake-shaped line (GJ338Bd voxel_relief_m 27->28, a correctly
reclassified lake district leaving the dry-relief sample set).
river_course and derivation-harness goldens unchanged. Full suite:
2114 passed.

derive_district_profile is now a thin wrapper over the shared
derive_at_metres_with_riparian core at survey-cell-centre world metres
— one derive core, two position sets. The batch pseudo-grid and the
true D-243 district grid were two coordinate systems sharing one bare
(i32,i32) type; the new SurveyCellPos newtype re-keys every batch
product (BodyWorldState.districts, Layer1Output.survey_basin_dirs) so
the compiler rejects cross-namespace passing.
Fixes two latent same-position divergences the T-1174 investigation
surfaced: three inconsistent latitude conventions collapse into the
core's single inverse mapping, and the region-climate baseline now
floor-divides true world metres instead of collapsing the whole body
onto region (0,0)'s baseline — batch climate becomes latitude/region
graded (D-245 direction: every changed believability metric increased).
Binding preservations per D-256(c): basin_direction rides a post-call
override with the true L1 D8 survey-cell aggregate (layer1's map
re-keyed to SurveyCellPos, identity lookup — a floor-divide lookup
against the pseudo-keyed map would have silently defaulted every cell
North); the riparian verdict comes from near_perennial_water_at, never
the empty-slice default (which would have flipped riverside
vegetation_class).
Quarter-skeleton morphology_zone now resolves at the settlement's
exact world position via derive_at_metres at work-item execution
(where TerrainAnalysisCache lives), replacing the survey-cell-centre
map lookup (D-256(d)); settlement_district_pos fixed to true-district
floor-division in passing (same doc/impl mismatch class). Second
pixel-vs-metre conflation fixed in aliveness_probe's anchor-walk math.
Window path byte-unchanged (window_derivation_golden 6/6 byte-
identical); derivation_harness golden untouched; believability golden
regenerated. Full lib + integration suites green.

The batch's real bug: extract_river_network computed the seaward
neighbor (nr,nc) to decide the MOUTH sentinel then discarded it, and
build_edges placeholder-pointed mouth edges at themselves — zero
chord, invent_course's degenerate 1-point return, resolve_mouth_
terminus dead code on real data, ALL real mouths resolving None, and
(because Ruling 3g retired the D/Q clip on the promise of real
termini) mouths vanishing at District/Quarter. The second instance of
the threw-away-the-answer anti-pattern Ruling 2b fixed for interior
pointers. Fix: river_seaward: Vec<(u16,u16)> on RiverNetwork

all_real_gj1c_mouths_resolve_to_mouth_terminus_not_none — 3/3, revert-
verified failing at the golden's first mouth (38,47). Mouth golden
coverage added (river_course_golden gains district_mouth/quarter_mouth
samples + non-degeneracy test; the previously Interior-only filter
gap closed). Tyre 1: the land-probe's dead dx/len*len arithmetic
replaced — station_spacing_m threaded through the crop path, probe
steps one real cell spacing, comment reconciled. Tyre 2: boxing
comment reattributed to variant-size balancing (Layer1Output retention
lives on TerrainAnalysisCache, not BodyWorldState). Hoshe #4:
cascade_golden's doc now states the attractor cascade accurately
(count-parity, not byte-identity — water_dist seeds from mouths).

The one additive server change of wave 1 per Tyre's carrier ruling:
river_class: Vec<u8> parallel to river_cells, serde-default-safe, no
new wire field. Log-scaled binning between RIVER_THRESHOLD and the
RIVER-RESTRICTED max accumulation (max over cells passing the is_river
elevation filter — NOT the grid-wide max, which peaks past the
coastline on wet large-ocean bodies and would starve the trunk class
exactly where Araminta's District-shows-trunk-only table needs it;
caught in lead review of round 1, fixed round 2). Log not linear
because accumulation grows combinatorially downstream. By construction
every body with rivers has trunk cells — pinned by a non-synthetic
regression on the committed GJ1c heightmap at the golden's exact
downsample. cascade_layer1.json regenerated: every pre-existing field
byte-identical (python-verified), only the new river_class arrays

directly, decoupled from OCTAVE_WAVELENGTHS_M[3] — a detail_scatter
retune can no longer silently redefine the Atlas rung floor. Direction-
agnostic const assert pins the coincidence so drift on either side

perturbation) — this regen records the sanctioned new baseline per the

Coast: WARP_OCTAVE_WAVELENGTHS_M 5->9 entries (262144m down to 1024m,
Quarter's Nyquist floor) with new min_wavelength_m cutoff plumbing in
coast_warp_px/warp_fbm (the warp previously had no cutoff at all).
Relief: invent_primitives feeds the VOXEL band (1024-128m, salted) into
elev_q/slope_q under the same envelope/cutoff discipline. Vegetation:
new vegetation_invention module — two-tier (BodyParams+latitude envelope
ceiling; single blended fBm field, never-gated 100-400km massif tier at

OUTPUT so precipitation/glaciation/vegetation shift as one world-fact;

Mid-implementation correction caught by tests: District's quantized
floor is 4096m (OCTAVE_WAVELENGTHS_M[3]), not 2x DISTRICT_M — the 8192m

only 2048/1024m coast + the voxel band are Quarter-exclusive. Docs and
golden cutoffs corrected to match.
New golden: tests/window_derivation_golden.rs + fixture (derivation_

Hoshe + Tyre review of the micro-habitat-mosaic branch requested changes on two
data-confirmed correctness bugs plus follow-through. All addressed.
Blocking:
- C1 (voxel.rs): the mosaic re-granted vegetation the climate withheld — a frozen
ice world (Edict) read 61% vegetated tundra. The Grassland apply-gate now fires
only where the climate already grants cover (!Barren); a climatically-barren
district (frozen < -50C = surface ice/geology D-239 §2, or hyper-arid moisture<5,
both resolved to VegetationClass::Barren upstream) is skipped. Genuine tundra
(cold + moisture>=15) is Scrub upstream and still reaches the tundra palette via
the same !Barren path. believability.json regenerated: Edict vegetated_districts
39->0, Arbour 20->8 (its real cold-pole/arid districts revert to barren);
intra-class variety preserved (Arbour vegetation_classes 3, micro_habitat_distinct 2).
- H1 (bodies.py): biosphere Gate 0 keyed on `inhabited`, conflating settlement with
biosphere and force-Airless'ing uninhabited-but-alive worlds (D-247: worlds were
alive before humans). Gate 0 is now settlement-independent — keyed on
atmosphere/hydrosphere/planet_class. 24 uninhabited-alive worlds now classified
(was 0); GJ0g-1 (dense atm + rivers) -> NativeMirror. Split 122 Compatible :
121 Mirror; all 9 canon exemplars hold.
Follow-through:
- C2 (bodies.py + D-247): Gate 0 now reads planet_class (barren -> Airless) as
D-247's "+ planet_class" phrasing names. D-247 amended to record the actual
two-gate signal set (atm/hydro/planet_class habitability; economic_base_primary
chirality; settlement-independence).
- C3 (believability.rs): micro_habitat_distinct criterion relaxed to `== 0 || >= 2`
— the min-over-patches estimator makes K=3 unreachable against a dominant-entry
palette; K=2 provisional, Q-123 calibrates.
- C4 + H2 (D-246): amended to record the v1 scope cut — only the Soil-derived
vegetated/wet classes take the mosaic; material-driven families are `_ => false`
so Hardpan/Scree are authored but unreachable in v1; no elevation change in v1;
the mosaic OWNS the §8 climate->vegetation law for the classes it touches.
- H3 (voxel.rs): three dedicated mosaic-pass regression tests — C1 barren-respect,
§8 material-untouched + forest-textured, T-1040 no-water-without-channel.
- H4 (voxel.rs): relief_signal comment corrected to ~[-1,+1].
- H5 (bodies.py): frontmatter override now strips quotes + validates against the

The mosaic palette gains a climate-biome dimension for the Grassland surface-class:
savanna / temperate / boreal / tundra now read distinctly rather than collapsing to
one biome-blind palette (the D-246 biome-awareness fix).
- atlas/mosaic.rs: ClimateBiome (from temperature_c + moisture_q) + four biome-keyed
Grassland palettes; palette(class, biome). Savanna carries scattered Forest copses,
tundra carries lichen + sparse bare ground and no forest. §8-safe (veg + water only).
- atlas/voxel.rs: derive the biome; a cold barren district (tundra/boreal) now takes
the sparse mosaic rather than staying blank — worlds that read "0 vegetated / blank"
now read structured-sparse (D-245 climate-appropriateness). vegetated_districts
8→20 and 0→39 on the cold validation bodies.
- data/mosaic_constants.toml: biome-keyed grassland mirror.
- docs/design/alien-ecology-vocabulary.md: Miri's full biome × register naming layer
(the cane/vane/wrack/husk/drum-root native lexicon + Earth-register names) — the
derived-label source for the palette and Phase-5 rendering.
Believability golden regenerated. Full server suite green. Forest biomes and the

Sub-chunk mosaic that modulates the D-228 axes into a spatially-coherent,
relief/moisture-conditioned mosaic of micro-habitats within a terrain class —
the fix for the aliveness probe's uniform "Wetland 100%".
- seed.rs: SeedDomain::VoxelMosaic = 12 (append-only; pinned-discriminant guard)
- voxel.rs: five new D-228 axis values (Vegetation::{Meadow,Deadfall,Lichen},
TerrainMaterial::{Hardpan,Scree}); the per-family-gated mosaic pass
- detail_scatter.rs: voxel_mosaic() selection field (~8-64 m band)
- atlas/mosaic.rs: surface-class palette + integer-basis-point weighted selection
with moisture-affinity conditioning; temperate/native baseline palettes
- data/mosaic_constants.toml: source-canonical palette mirror
- believability.rs: micro_habitat_distinct metric + D-245 intra-class criterion
v1 scope (D-246-faithful): modulates vegetation + water only, in the vegetated
classes (Wetland/Forest/Grassland), so the D-239 §8 lithology law is untouched;
water is gated on the T-1040 has_active_channel hydrology rule. Material variants
(hardpan/scree) and the extreme classes are a §8-aware follow-up; the biome-aware
palette variants (T-1085 vocab) extend the baseline before generation.
Goldens regenerated (believability + derivation). Full server suite green.

The push gate's integration tests (not in cargo test --lib) caught two regressions
from the relief change:
- derivation_harness::cross_district_elevation_blend_reduces_seam_step — the relief's
large per-position term (span 300 → ±200 m, far above the compressed elev_q/2 base)
swamped the T-1042 seam measurement and clamped heavily at sea level. Fixes:
(1) shift the voxel-relief octave band to 0.13–1 km (all sub-district, dropping the
2 km octave that competed with elev_q's district role); (2) reduce VOXEL_RELIEF_SPAN_M
300 → 100 so relief stays mostly below the base (fewer sea-level clamp artifacts,
proportional hills); (3) rewrite the seam test's avg_elev to average over an 8 km
multi-wavelength y-transect so the zero-mean relief cancels, isolating the base seam.
- derivation_harness::golden_seed_determinism_regression — legitimate golden refresh
(determinism still holds; elevation values changed intentionally).
Believability relief now ≈22 m mean (was 5 m flat; 59 m at the over-aggressive span 300)
— navigable hills without clamp artifacts, 7/8 criteria. Both goldens regenerated; full
cargo test (38 binaries) + clippy --all-targets -D warnings green. D-239 amendment +
Q-123 item 4 updated to the final span/octave/numbers.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The voxel tier read flat (the D-245 "0–3 m, no hills to navigate by" bug):
family generators set elevation from elev_q at a compressed scale plus only ±4 m
micro-scatter, and detail-scatter's mid-scale relief (D-243 §2) only ever reached
the district tier (elev_q), never per-voxel elevation_m.
- detail_scatter.rs: extract the enveloped-fBm core; add `voxel_relief` at the
0.25–2 km octave band (vs the district 4–40 km band).
- voxel.rs: add the mid-scale relief post-dispatch in derive_voxel_column, body-global
SeedDomain::VoxelRelief seed (position-keyed), f64 truncated to integer metres (D-010).
Envelope = slope_q*3 + elev_q — the coarse heightmap gives slope_q ≈ 0 even on high
ground (Arbour max 13), so elevation must drive ruggedness. Flat families only
(Alluvial/Lava/BraidedDelta/Dune/Meander); the dramatic families already carry strong
internal relief and WaterBody stays at sea level.
- seed.rs: SeedDomain::VoxelRelief (D-224 domain separation).
- believability.rs: new `contrast.voxel_relief_m` metric — mean within-district elevation
range over a 2 km transect (a single 64 m sample chunk is narrower than the relief
band) + a "voxel relief" criterion.
Arbour @ yolo: voxel relief 5 m → 59 m, 6/8 → 7/8 criteria (remaining fail = the
Q-123 vegetation-denominator item). Edict 59 m. Golden regenerated; 1586 lib tests +
believability harness (determinism) pass; clippy -D warnings clean.
D-239 amended (T-1081); Q-123 item 4 updated. Deferred to Q-123/follow-up: the
provisional span + threshold, and a per-body hypsometric absolute-elevation model.

Stack review (Hoshe + Tyre) of T-1083+T-1082+T-1080. Every finding fixed or disposed:
- believability.rs sample_indices: replace the rejection-sampling loop (could stall
when n ≈ take) with deterministic partial Fisher-Yates — O(n), guaranteed
termination, distinct, sorted (Hoshe+Tyre).
- believability.rs drainage proxy: exclude water-body districts (all elev 0, no banks)
and require both wet + dry voxels — they were passing vacuously and inflating the
metric (Hoshe).
- believability.rs read_cities: log skipped malformed rows instead of dropping silently
(Hoshe).
- voxel.rs: add the 3 WaterBody zones to all_families_no_panic_at_extreme_positions +
fix the "7 families" comment (Hoshe).
- climate_constants.toml: bold warning that [moisture_gradient] is not loaded until
T-1032 — tune ClimateConstants::default() (Tyre).
- Q-123: record the per-zone "water renders wet" threshold + the land-relative
vegetation-present denominator as calibration items (Tyre + the open 7th criterion).
- T-1083 ticket: note the sampling-fix attribution (landed in the T-1082 commit).
Believability golden regenerated (sampler + drainage fixes moved the metrics).
clippy --all-targets -D warnings clean; 1580 lib tests + harness pass.

moisture_q was a single body constant (derive_moisture_q took only &BodyParams →
80 for every one of 2048 ocean-world districts), so vegetation/terrain/ecotones
were uniform — "nothing to fuzz" (the T-1080 believability bug).
- district_profile.rs: derive_moisture_q is now a body ceiling (hydrosphere+atmosphere)
× per-district gradient — latitude (equator wet → pole dry), elevation (orographic/
rain-shadow), continentality (100 − ocean_fraction_q). Integer/D-010, no new plumbing
(elev_q/ocean_fraction_q/latitude_deg already reach build_district_profile). Mirrors
D-240's temperature model. Coefficients in ClimateConstants + climate_constants.toml
[moisture_gradient] (provisional; Q-123 calibrates). Tuned so a wet body stays mostly
green with drier patches and a frozen body clamps mostly barren. + gradient unit test.
- region_profile.rs: region-tier moisture gets the region-latitude gradient (elevation/
continentality are district-scale).
- Propagates to precipitation_class / vegetation_class / morphology_zone (all read
moisture_q). D-239 §2 amended. Believability golden regenerated.
Probe (Arbour @ yolo): moisture_q distinct 1 → 49 (spread 0 → 48); 5/7 → 6/7 criteria.
Edict (frozen): moisture 0..20 ×21 — gradient within its low ceiling. Remaining fail
(vegetation-present) is the metric dividing by all-sampled incl. water on a 2/3-ocean
world — a Q-123 calibration concern, not a climate defect.

The water zones (OpenOcean/Lake/TidalFlat) fell through to the dry-land AlluvialPlain
fallback, so the sea rendered as dry forested land (the D-245 believability bug).
- voxel.rs: new MorphologyFamily::WaterBody (9th family) + generate_water_body,
dispatched from zone_to_family. Deep open water with a Shallow shoal band on the
district-anchored coast line (wider for shallower bodies); TidalFlat all-Shallow.
Seabed Rock (steep) / Sand (gentle) / Wetland (tidal mud); Vegetation::Barren;
water surface elevation_m = 0; seasonal Ice via derive_cover (frozen seas). Wetland
stays AlluvialPlain (it is land — a marsh, not open water). Integer/D-010. + 4 tests.
- believability.rs: fix a sampling bias in the T-1083 enforcer found while verifying
this — the metrics sampled the first 64 districts in BTreeMap order (a spatial corner,
e.g. all-ocean), which reported a forested world as "0 vegetated". Now a deterministic
seeded spread across the body (matches D-245's "randomly-sampled locations").
- D-239 amended (§5 8→9 families; §6 refined — the 3 water zones now dispatch to
WaterBody). Believability golden regenerated.
Probe (Arbour @ yolo): water-renders-wet 4/64 FAIL → 42/44 PASS; terrain-material
variety 1 → 4 PASS; 3/7 → 5/7 criteria. (Remaining fails — moisture gradient,
vegetation-present — are T-1080.)

Promote the throwaway aliveness probe into a committed, repeatable believability
protocol — the instrument that found T-1080/T-1081/T-1082.
- atlas/believability.rs (new): BelievabilityReport (serde) + analyze() computing
CONTRAST (per-field min/max/distinct for moisture/elev/slope/ocean over all
districts; distinct morphology zones / vegetation classes / terrain materials)
and COHERENCE (water-renders-wet, drainage-monotonic, vegetation-present) — never
marginal per-tile counts (the lesson: that called a broken uniform world ALIVE).
evaluate_criteria() = advisory D-245 checks; cascade_for_body()/seed_to_u64()
loader shared by the bin and the harness. Unit tests prove the metric tells a
uniform world (fails) from a varied one (passes) + determinism.
- bin/aliveness_probe.rs: refactored to a thin CLI over the module — prints the
body-level report + advisory D-245 criteria, drops the naive per-tile verdict.
- tests/believability_harness.rs (+ golden): runs the real cascade for Arbour
(temperate/ocean) + Edict (frozen/ice), asserts determinism, golden-snapshots
the reports (regression — updates when T-1080/T-1082 land), advisory criteria
with BELIEVABILITY_STRICT=1 to fail on unmet D-245 criteria. Skips if committed
data absent. x86_64 golden (cascade has f32 warp paths).
Baseline @ believability-v1: Arbour 3/7, Edict 3/7 criteria pass — moisture
gradient, water-renders-wet, drainage all FAIL (T-1080/T-1082); Edict vegetation
0/64 (blank tundra — the frozen 'reads dead' case D-245 targets).
PNG layer maps (ticket item 3) deferred — explicitly optional; the contrast +

Phase 2 of the D-243 re-scale. The ~1km carrier is renamed and re-scaled to
the 2km district, and every consumer reads scale from the canonical scale.rs
instead of a local literal.
- region_profile.rs -> district_profile.rs; RegionProfile -> DistrictProfile,
RegionPos -> DistrictPos (re-exported from scale::DistrictPos), derive_*_regions
-> derive_*_districts, across all 10 consumers + the derivation harness.
- chunk_context now references scale:: for the carrier cell: district 1024m -> 2048m,
shift 4 -> 5 (CHUNK_DISTRICT_SHIFT). This caught a real latent bug: the seed-district
index used a literal '>> 4' while the anchor used the constant, so same-district
chunks could derive different anchors — now both use scale::CHUNK_DISTRICT_SHIFT.
- derivation_harness scale literals ('>> 4', '* 1024', '0..16') converted to
scale:: constants (the same drift the canonical source eliminates). Believability
tests pass at 2km; the voxel determinism golden re-pinned (anchors moved with the
re-scale — deterministic, intended).
Full suite + clippy --all-targets -D warnings green. The district DERIVATION still
tiles the heightmap at 8 cells (the old coarse path); replacing it with on-demand
heightmap interpolation + detail-scatter is phase 3.

derive_chunk_context now derives channel_anchor_m and coast_anchor_m from
the Region-or-higher seed path (D-239 §10); all five voxel placement sites
measure distance to these anchors in continuous world coordinates:
- T-1040: compute_channel_state / compute_meander_reach_channel /
in_levee_band subtract the region anchor instead of measuring from the
world origin axis — active channels now exist in their chunks anywhere
on the body, continuous across chunk boundaries. has_active_channel is
honest in both directions (band-crossing gate; floor covers the
BraidedDelta belt at short wavelengths).
- T-1041: fjord/cliff/gorge/delta drop their rem_euclid(64) chunk-frame
folds — one valley/coastline/fan per region instead of one per chunk.
D-239 §9 chokepoint widths preserved; two i32 wall-rise overflows on
region-scale distances fixed by clamping before multiply.
Harness: 6 new believability tests (channel presence + gate honesty at
chunk (1000,-750), cross-boundary continuity, one-landform-per-region,
braid-belt confinement); drainage sweeps strengthened with anchor-band
chunks. Voxel golden regenerated deliberately: case A now pins a genuinely
in-channel Shallow voxel on the anchor, case C a Deep trough voxel
matching its label; case B byte-identical and L0/L1 cascade golden
untouched (no upstream leak). Review: approved, three minors addressed
(truncation-convention docs, delta gate floor, case C relocation).

Adapt the believability/budget verification harness to the T-1033 BodyParams
strip: validation-body fixtures (Kallast/Glødberg/Marevna) no longer set the
removed orbit/star fields (orbital_period_days, axial_tilt_deg, spectral_class,
star_type). Temperature is now derived from the planet_class envelope (D-240),
so the Marevna validation note/assertion is rewritten — oceanic band [-12,28]°C
+ maritime 0.6 + standard-atmosphere greenhouse yields ~+26°C at the equator
(was a stale ~-56°C orbit-equilibrium note). Add the seed→tile golden fixture
(tests/golden/derivation_harness.json) that the determinism regression locks.
Also fmt the harness and fix one clippy lint (iter().copied().collect() ->
to_vec()) — the file predated the pre-push gate's cargo-test/clippy coverage.

Close the last D-234 piece — terrain water-direction extraction wired through
to founding orientation and the quarter waterfront rule:
- Layer 1: TerrainAnalysis::water_bearing — 8-octant integer bearing toward the
nearest water from the water_dist gradient (D-010, no atan2). Stored on
GeographicAttractor.water_bearing (360 = none).
- #956 founding orientation: coastal/river settlements now get a real
water-facing bearing (the anchoring attractor's), replacing the 0 stub.
- #957 waterfront rule (D-234b): the water-facing quarter edge (from the
settlement's Coastal founding orientation) drops its block setback to 0 so
buildings present flush to the quay (dock-orthogonal). Typed Edge + coastal_edge
+ per-block gating.
Golden + atlas_response fixture rebaked (additive water_bearing field only).
8 new tests. All integer-deterministic (D-010).
Pending: the waterfront rule reads context.founding_orientation, which
city_context_reader still stubs to Cardinal — real per-settlement orientation
reaches quarter generation once the Layer-3 placement -> Layer-4 GenerateSkeleton
dispatch is wired (the remaining cross-layer integration).

DrainageBasin gained a territorial_status field, so the Layer-1 golden and the
atlas_response msgpack fixture pick it up. Both changes are additive/
representational — basin/attractor/river selection is unchanged.
- cascade_golden.rs: pass None dominant_faction; golden rebaked (only
"territorial_status": "FrontierUnclaimed" added per basin).
- gen_fixtures.rs: set the new field in the atlas_response generator; fixture

Wire the existing attractor-matching engine (#919/#925) into the
generation cascade as Layer 3, and make the whole placement-scoring path
integer-deterministic.
Layer 3 (D-211):
- CascadeLayer::Settlement + Layer3Output (placements) on the snapshot;
BodyWorldState gains a `placements` field (the D-203 hot cache).
- run_layer3 runs the five-phase match_cities against Layer-1 attractors
via the authored D-195 compatibility matrix; pure function of
(attractors, cities) — no RNG. cities are passed in by the caller so the
cascade stays DB-free and testable. A `// cache seam` marks where a
persistent cache wraps it later (#1021).
- gen_queue passes &[] for now (Topography needs no cities); the runtime
settlement read (gen_queue/layer_proxy) is the #955 follow-on.
Integer determinism (D-010 / D-227 — D-195 amended):
- Wiring match_cities into the deterministic cascade made its f32 scoring
a live cross-platform divergence risk (a near-tie comparison or the
Hungarian's f32 reductions can round differently per platform → a
different world from the same seed). Converted the entire path to
integers: CompatibilityMatrix is a 0-100 affinity table; attractor
strength is 0-100 and terrain cost is a percent (100 = baseline),
quantized once at the Layer-1 feature boundary; cell_score, the
Hungarian, and CityPlacement.score are i64. No f32 in any placement or
ranking decision.
- Layer-1 golden fixture rebaked: confirmed selection/positions are
unchanged (same 256 attractors, 93 river cells) — only the strength/cost
representation changed.
Tests: lib green (1292); new settlement_layer_places_cities_deterministically
covers placement + determinism + propagation into BodyWorldState.

Two Layer-1 generation fixes surfaced by the per-layer atlas viewer:
- Layer1Output now carries grid_w/grid_h (the downsampled working-grid the
positions live in). The client maps overlays from these, so the scale is
correct for any source heightmap resolution rather than assuming the texture
size — fixes overlays projecting at half scale into a corner.
- Drainage basin boundaries are traced as ordered, non-self-crossing contours
via Moore-neighbour tracing instead of an angle-from-centroid sort. The sort
produced star-shaped, self-crossing polygons for concave basins that rendered
as straight chords across the map.
Golden (cascade_layer1.json) and the cross-language atlas_response_ready
fixture regenerated. 100 atlas lib tests + the new tracer test pass.

Addresses the Hoshe (QA) + Tyre (architecture) review of the SeedChain/cascade
work:
- Golden was pinning an empty river network (128x64 produced 0 river cells).
Bumped to 256x128, where GJ1c yields a real network (93 river cells, 19
mouths) — Layer 1's rivers are now actually guarded, not just attractors.
- SeedChain::for_body(world_seed, body_id) + fnv1a_64: the single canonical
body_id(String) -> u64 path (FNV-1a, the repo convention), so callers can't
derive divergent worlds from the same seed via different ad-hoc hashes. The
golden now uses it.
- Stability guards: seed_domain_discriminants_are_pinned test (CI fails if a
SeedDomain tag is renumbered); AttractorType gains #[repr(u8)] + explicit
discriminants (it's cast as a sort key in features.rs).
- Tests: SeedChain::root(0) non-degenerate; run_cascade error path (missing
file -> Err, not panic).
- Comments: clarified the id=0 derivations (sibling separation is caller-side
via the per-district/quarter chain; #957 threads the index), tightened the
all_district_types reachability comment (it pins the seed-0 sequence, not a
probabilistic claim), and noted the golden's WORLD_SEED is cosmetic at
Layers 0-1 + the x86_64 f32 capture caveat.
Deferred with reason: the run_cascade -> CascadeInputs struct refactor (Tyre)
is left for #954 — designing Layer-2's context shape now would be later-phase
detail, and there's a single caller to migrate then. EntityRng keeps its
domainless combine (migrating is stream-changing) — noted in D-224.

End-to-end determinism guard. cascade_golden.rs pins two artifacts for a real
committed body heightmap (GJ1c) in one diffable JSON golden
(server/tests/golden/cascade_layer1.json):
- Layer 0: SHA-256 of the source heightmap.png bytes (flips if the Python
heightmap generator or the file changes)
- Layer 1: the serialized Layer1Output of run_cascade on a 128x64 downsample
(flips if the Rust drainage/feature/sub-biome code changes)
JSON (not the msgpack discussed in refinement) to match the existing
golden_suite.rs convention and stay diffable — a failure shows what drifted.

Remove the peripheral sector (100° half-angle, reduced range) and blind
spot classification. The server now sends only tiles within the 120°
forward cone; the client renders previously-explored tiles behind the
player with a light fog overlay instead.
This eliminates complexity in both the cone classifier and the snapshot
protocol while preserving the core information asymmetry — you still
can't see behind you, and the monologue system (D-016) still bridges

Server-side infrastructure for information asymmetry in dialogue.
NPCs display role labels (Worker, Supervisor, Patron) instead of
real names until the player explicitly learns them via KG lookup.

color indices on the wire with serde(default) for compat.
