Tyre's PR #209 finding: every prior D-226 re-scope carries a dated
amendment in the record, and this vocabulary change existed only in
code comments and ticket appends. Records the drops (select_city,
open_regional — no settlement hit-test affordance post-D-255; one
screen Region..Chunk), the additions (open_atlas, jump_to_center via
the constrained jump_to seam), the summary-field reconciliation, and
the in-process-only transport narrowing.

Records the T-1192 presentation ruling: the Global opener's display
ratio is viewport-fitted per body to the largest integer px/gridunit
that fits the legend-reserved viewport (floored at 1x1, letterbox
centred), texel-exact by construction; fixed rungs keep their tuned
constants. Explicitly notes that non-integer resting-state scaling
remains unsanctioned and that a PR #205 review finding removed a
fractional-fit branch which had cited this record for an exception it
does not contain — the mis-citation episode is part of the record so it
cannot recur silently.

Records the T-1174 ruling: derive(seed, absolute world metres) via the
derive_at_metres family is the only derive core; the batch 64x32
pseudo-grid is re-scoped as a survey raster with a real SurveyCellPos
newtype (role name, not a D-243 rung); derive_district_profile becomes
a thin wrapper at survey-cell-centre positions with binding basin and
riparian preservation; point-feature terrain judgments move to exact
world positions; D-255 step canvases are fenced to the window family.
LayerRegionOutput rebuild deferred to T-1181 (tripwire verified: sole
reader is the region_grid overlay); voxel carrier deferred to Phase 5.
Consults: Tyre APPROVE-WITH-CHANGES, Dudley FEASIBLE-WITH-CHANGES —
both incorporated. Discharges the T-1174 blocker on D-255's T-1181
step-canvas envelope.

Jeroen's gap catch: T-750 never stated that the seed-to-tile cascade is
also what determines the world where the player walks. Now connected in
one statement across three homes: D-012 amendment (the founding 'chunks
load/unload around the player' driver now concretely = the D-227/D-239
cascade; 3x3 chunk neighborhood minimum, coarser context self-provided by
D-255(f) function composition, Atlas interaction never a precondition,
byte-identical either way), the matching T-750 deliverable note (in
changelog), and a one-truth consumer note on Q-093 for the Phase-5 insert
minimap (design deferred, no independent map pipeline expected).

Tyre's two governance sentences on the D-226 course note: (a) the
Godot rasterizer floor makes per-class course WIDTH differentiation
inert at every shipping fit zoom — classes distinguish by opacity
alone until T-1175's per-vertex tapering; the 'trunk widest' promise
is design intent, not current pixels. (b) The pole-row edge-drain
branch is structurally unreachable; the real mechanism is interior
k<0 (revert-verification discovery). Plus the dangling cargo-fmt
reflow in the course-cost bench from the gate-bounce round.

Tyre's binding ruling from the three-audit design pass (full text:
docs/architecture/river-courses-t1170.md). Keystone: the wave-1
carrier rule refines three-way — rung-independent discrete features
ride whole-body; continuous fields ride windowed per-cell arrays;
RUNG-INDEXED INVENTED DETAIL rides the windowed payload regardless of
geometric kind (courses = the coast crinkle's vector sibling; no
ceiling impact — content of the one windowed payload, not a second
query). Courses invented server-side per window on the T-1137 queue,
terminated against the window's own rung-consistent water verdict
(the two-waterline terminus fork dissolves); Region's skeleton chords
ARE the rung-truncated course. river_downstream sentinels reserve
TERMINAL for future endorheic basins. D-226 + D-227 captures added.

The drawn coastline is a family of curves indexed by rung (warp cutoff
admits more octaves at finer rungs), so no single authoritative server-
side waterline exists — reconciliation is a presentation-frame
operation at the draw site; the skeleton stays rung-independent. Clip
retires into T-1170's coast-terminating courses.

I1: _draw_attractor_shape's three stroke-width args (Confluence arc,
Coastal/NaturalHarbor arc, Oasis spokes) were raw screen-space literals
— Godot multiplies stroke widths by canvas scale exactly like radii, so
at the Region orbital fit zoom the outlines rasterized at ~0.01px, the
identical sub-pixel class the dot/ring compensation fixed, missed on
glyph internals (and attractors are Region-only — precisely where it
bites). Widths now arrive pre-compensated via a px_w param, keeping the
primitive pure. Regression pin: a source-scan test asserting no
draw_arc/draw_line in the function carries a bare numeric width (the
draw-smoke suite documents its own vacuous-pass mode, so source-scan is
the environment-independent gate); revert-verified by name. I2: D-226
visibility-direction sentence — Araminta's fade-down inversion recorded
as pre-T-1170 with its single revisit point named. I3: class-header
call-site claim corrected (enter() funnels through _enter_at_rung).

Rivers/basins/attractors ride the existing whole-body layer1 field —
neither AtlasLayerResponse ceiling touched, no tagged-envelope
migration. Per-rung refinement is client-side class filtering on the
additive river_class (distinct from T-1162's server-side Nyquist
cutoff: a fixed finite graph has nothing to truncate). General rule:
discrete map features ride the whole-body overlay family filtered
client-side; continuous per-metre fields ride the windowed per-cell
arrays — wave 2's roads/settlements inherit this unchanged. Riparian
vegetation response is the named T-1168 forward contract, deferred.

Tyre's exact capture: the design pass's 'retire COMPOSITE_SMOOTH /
crisp draw_rect as the only path' is superseded — the const survives
as the compile-time pipeline axis, the crisp path stays as debug/
compare, and crispness-at-sparse-rungs is delivered by the per-rung
sampling-filter policy instead. T-1155's retirement framing is
cancelled (ticket closes on merge). Also records the R2 softening:
the T-1162 relief band adds sub-district elevation variance at
Quarter cutoff, so temperature no longer steps strictly at the
district there — intended, noted so nobody is surprised later.

All Hoshe/Araminta findings addressed (Tyre approved outright), none
retracted — plus a Dudley stop-and-flag discovery that improved on the
asked-for fix:
- Legend 100x lie (Araminta, blocking): subtitle computed via
spacing_for_rung() and refreshed at all three _held_granularity_v2
write sites. Region test asserts 204.800 km/cell; the District
direction needed a stale-header-aware helper — a District-only test
spuriously passes against the old literal by coincidence.
- Region coalescing coverage (Hoshe 1): both directions tested
(Region-vs-District separate slots; Region-vs-Region coalesces).
- Clamp boundary tests + dangling citations (Hoshe 2): writing the
requested halving-loop-fires test surfaced that the loop is PROVABLY
UNREACHABLE at current constants (per-axis clamp forecloses it —
brute-forced independently on both server and client sides). Ruling:
the loop stays as defensive code; the test became a property sweep
pinning both the wire-cap invariant and the loop's no-op status (a
future constant change breaks it loudly); doc comments on both sides
drop the load-bearing framing and state the truth; the old client
mirror test that claimed the loop fires (passing on the per-axis
clamp alone) is replaced the same way. Client citations now name the
real server tests verbatim.
- Governance (Tyre): D-226 amendment note — progressive cross-rung
refinement EXTENDS T-1124 §4 (not supersedes); legacy u32 field
scheduled for retirement (T-1159).
Server: 1818 lib tests green, clippy/fmt clean. Client: zoom_ladder
48/48, window_request 26/26, viewer 74/74; gdlint clean. Every fix
revert-verified.
All seven Hoshe/Tyre findings addressed, none retracted:
- n-clamp/echo/staleness triangle (Tyre C1): client _clamp_window_n_mirror
(bit-for-bit twin of the server clamp, canonicalize_district_center
precedent) applied before _n is stored/sent; server test pins the
quarter n=32 -> echo 16 contract.
- min_wl band quantization (Hoshe 1/Tyre C3): quantize_min_wl_m snaps to
MIN_WL_BANDS_M {0, 32768, 16384, 8192, 4096} before cache key and echo
(design doc §5's unbounded-key fix), reusing the one true
OCTAVE_WAVELENGTHS_M array; docstrings now state the server-quantizes/
client-sends-raw split; same-band cache-sharing test.
- coalescing granularity axis (Hoshe 2): two tests pin different-
granularity requests as separate in-flight slots and same-granularity
coalescing unchanged.
- orphaned fixture (Hoshe 3): test_protocol.gd consumer decodes
atlas_response_ready_with_window.msgpack through the real IPC path and
asserts the new fields.
- atlas_window_request coverage (Hoshe 4): new test file — stale-drop on
granularity mismatch, old-server-shape defaults accepted, clamp mirror
formula + wiring. First draft's quarter-via-request_now test would have
passed for the wrong reason (request_now resets granularity by design
until T-1153) — split into formula pin + reachable-path wiring proof.
- granularity type seam (Tyre C2): field + resolver docstrings state
finer-only integer multiples with resolve_window_granularity as the
single widening point; matching contract note added to the D-226
T-1143-rulings amendment.
cargo --lib 1807/1807; goldens bit-identical; gdlint clean.
Jeroen's three rulings on the zoom-ladder design pass, recorded as a
D-226 amendment: (1) 'we set a new BHAG so old restrictions are up for
debate' — the item-(d) ceiling opens for the Atlas windowed viewport
(below-quarter rungs gated on the T-1154 measurement pass; chunk/tile
still never a whole-body planetary layer); (2) planetary rung ships as
progressive capped-density tiling on the generalized district_window
carrier; (3) planetary->regional entry becomes continuous cursor-anchored
zoom with full-zoom-out resetting to the canonical orbital frame (D-013
zoom-owns-descent restored; click-through cut superseded).
Design doc stamped with the resolved rulings. T-1143 closed. Implementation
chain: T-1149 (derive_at_metres + octave cutoff) -> T-1150 (granularity
carrier + aliasing test) / T-1151 (window par_iter) -> T-1152 (derived
planetary rung) / T-1153 (client continuous ladder) -> T-1155 (smoothing
retirement); T-1154 below-quarter measurement gate.
Jeroen's same-day corollary to the zoom-ladder condition: no zoom level
displays the authored heightmaps directly — even the orbital/planetary map
is derived output, sampled at canvas resolution (continuous field, not
fixed rasters). Kills zoom over/undersampling by construction and makes
the map viewport-adaptive. import_heightmaps survives as input storage
only; AtlasViewer's texture display path retires when the derived
planetary rung lands. T-1143 design pass extended with items (e)-(g).
Jeroen's ruling from the Groombridge/Lendel zoom-ladder captures: the BHAG
stays 'a Reach a character can travel through'; the Phase 4 exit bar now
additionally requires a continuous Atlas zoom ladder (planetary map -> tile
scale, each level deterministically derived at native granularity, never
magnified interpolation). Evidence in the record: the 16-district window is
sub-pixel vs its heightmap source at Lendel scale, so everything below fit
zoom is D-227 invented detail that must be derived, not smoothed.
CLAUDE.md Phase-4 row carries the condition; T-1143 (the ladder design
pass) appended + raised to high — it and the D-226(d) floor question are
now phase-gating.
Cover-fit: fit_window_view zooms from the viewport's LARGER dimension,
no margin factor (any factor under 1.0 leaves a long-axis gap — checked
numerically) — the composite fills edge to edge, overhanging the short
axis into pan-space; the refloat center-equality early-return already
prevents refetch churn at rest (proved, not just tested).
Input model (Jeroen: drag breaks click semantics with map objects):
LMB-drag pan REMOVED from the regional window; clicks are
object-reserved. Pan = held WASD/arrows polled in _process (delta- and
zoom-scaled, camera-pans-toward-key convention verified numerically)
plus edge-scroll within 24px of the viewport border; both suppressed
over UI and on OS focus loss; both set _user_adjusted; wheel zoom and
Esc unchanged. Reads RAW physical keycodes deliberately — independent
of the shared D-054 move_* InputMap actions bound to the same keys
(whose occlusion-leak is pre-existing and now ticketed as T-1146).
Pole wall + east-west wrap unchanged, re-driven through the new
inputs; drag tests replaced, not kept.
Smoothed composite (interim pending T-1143): per-cell colors bake into
an n x n Image/ImageTexture (exact existing colorizer incl. overlay +
ice tint) drawn once with LINEAR filtering — GPU bilinear reads as
terrain, the planetary heightmap's own treatment. Crisp per-cell path
preserved behind COMPOSITE_SMOOTH for T-1143 A/B. Rebuild only on
reference-identity change of window/toggle (is_same — verified true
reference equality; value-equal distinct dicts DO rebuild).
Governance: T-1145 amendment paragraph on D-226 T-1124 SS5 (all three
supersessions); pql decisions validate ok.
Suites: window_viewer 74/74, window_geometry 32/32, window_overlay
(new) 16/16; gdlint clean on all six files.

SS4: the 7/29ms per-window figures now state their warm-analysis
assumption — the first window on a body additionally pays one ~45ms
run_layer1 into the lazy per-body LRU on the GenerationQueue
(capacity 8, browsed-bodies-only, recency eviction, eviction re-pays);
subsequent windows any (center, n) hit the LRU. SS5: the glaciation
tint gate corrected from >= Light to >= Moderate, matching
apply_ice_tint's reference gate (Light is erosion signatures, not
visible ice) — code stood, prose was wrong.

The regional-map entry changes from zoom-threshold LOD swap to
explicit click-through: the planetary heightmap view becomes FIXED
(pan/zoom removed together with its replacement in T-1138, never
before); hovering shows a rectangle cursor representing the
regional-mode bounds; click descends centered on the click point's
derived DistrictPos. DISTRICT_WINDOW_MIN_ZOOM retired before ever
being built; D-013's zoom-owns-descent superseded for this seam only
(click owns descent). In-mode behavior unchanged (pan-only refetch,
debounce, cache, border-fade). Morph transition explicitly deferred.
Open at T-1138: the rectangle is an affordance, not to scale — n=64
is ~131 km = a few px on a planetary canvas; resolve the honest
representation in the screen design. T-1138 description updated;
T-1140 filed for the two companion UI defects fixed alongside.

All five findings applied, none touching the option-(c) carrier choice:
(1) SS2 gains a binding windowed-family ceiling — exactly ONE
windowed-query field; a second windowed query is a dedicated response
message by rule (two concurrent windowed payloads would need the
per-field request-correlation that IS the tagged framing — that is the
trigger to build it); symmetric with the request side's five-hard cap.
(2) SS1 gains a binding serving model — window derives ride the same
Rayon queue + Pending pattern as whole-body cache misses, never inline
in the PreInput drain (which the codebase deliberately keeps expensive
work off); per-connection coalescing recommended; SS4's 7/29ms figures
reframed as worker latency, not tick-thread cost. (3) The
layer_proxy.rs growth-ceiling comment (comment-only diff) now records
the T-1124 ruling as RESOLVED — scoped to the dense whole-body family,
district_window outside it, second windowed field = dedicated-message
migration — instead of deferring to an open design question. (4) SS2
documents that body scoping rides the enclosing AtlasLayerResponse
envelope (cache key body_id+center+n; echo disambiguates within-body).
(5) SS5 entry clarified: zoom threshold alone triggers the swap
(works over open ocean), first window centers on the pan-center's
derived DistrictPos; downstream settlement-anchoring phrasing
reconciled.
pql decisions validate clean.

T-994 — three-phase draw replacing the flat splitmix64 flavor pick:
- Phase 1 body K-draw (trait_draw.rs): hard gates -> soft weights (two-part
geographic_sector join, PR #148) -> SeedChain::for_body-seeded weighted
draw of K (5/3/1/0 by ComplexityTier), pins count toward K, coverage-aware
over a new body-level district-type-mix aggregate threaded into
CityGenerationContext at L3->L4 dispatch.
- Phase 2 district-dominant pick keyed by the D-243 2048m District cell —
settlements sharing a cell independently derive the identical template.
Resolved at dispatch, never in FillChunk (T-987 stays pure).
- trait_catalog_reader.rs: systems.db reader for trait_templates +
atlas_body_trait_bias (D-225 resource pattern), registered in main.rs
with graceful degradation.
- BlockSkeleton carries district_type; assign_block_tags is a pure lookup.
T-1003 — deviation/swerve system (trait_swerve.rs):
- ArchitectureFlavorRef is now InVocabulary(u8) | Swerve(tag).
- Rare per-building wildcard: foreign-import pool (other corridors +
cross_corridor) driven by Epicenter/Passage tier, mixed faction,
road-graph degree; heritage-callback pool (own-corridor heritage) driven
by isolation, remote tier, founding_age_years. Integer bps, base 100,
cap 300 per driver — placeholder constants pending calibration.
- Sparsity escape hatch = same mechanism, necessity-triggered at the
phase-2 pick (deterministic max-weight over the hard-gate-eligible pool).
- New SeedDomains: TraitVocabulary(13) / TraitDistrict(14) / TraitSwerve(15).
Governance: D-232 amended (district pinned to the D-243 2048m tier — the
D-222/D-243 redefinition was never captured; swerve driver mappings +
placeholder rates recorded), D-229 flavor_ref field updated to the enum
shape, D-235 amended (T-995 vocabulary ratification note; rides here due
to single-file entanglement).

apply_move no longer writes Facing (was the only movement-facing coupling,
player-only); the player's view changes solely via explicit SetFacing.
NPC path-follow now sets Facing to the step direction — a strict improvement
recorded as a D-252 correction: NPCs previously never received Facing from
movement, their cones sat at spawn direction while walking. Bump-to-turn
retired (blocked moves change nothing) with a regression test for each
semantic. Wire schema unchanged; player_facing docs now say view/aim.

VIEW and must never rotate the body — the follow-only commit flag
generalizes and disappears); the layered head/torso look-at runs during any
movement, WASD included; the ~100ms post-step re-assert mitigation is
removed as dead (server-side facing_from_delta removal lands separately).

D-249 (architecture): 'server feet, client eyes' facing split with the

Tyre's re-review found the C1 !Barren guard only covered the Grassland arm — the Wetland arm was an unconditional => true. Since derive_morphology_zone has no temperature gate, a frozen + wet + flat district still yields Wetland material, so the wetland palette would paint copse/bog onto frozen marsh: the exact C1 symptom via the material path. Not a regression (the arm was unchanged) and unreachable by the 2 harness bodies, but the D-246 amendment + the voxel.rs comment already claim the guarantee universally, so the gate must match the claim.
Gate is now: apply = !Barren && class in {Wetland, Forest, Grassland}. Behavior change is limited to frozen/hyper-arid Wetland districts (a temperate marsh is never Barren-dominant; Forest is Barren-free by construction). believability.json unchanged (neither harness body reaches the frozen-wet case). New regression test mosaic_pass_does_not_revegetate_frozen_wetland; D-246 amendment reworded to the unified gate. Full cargo test green; clippy -D warnings clean.

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
4-value enum (warn-and-skip on typo).
systems.db regenerated + stamped (H1). believability golden regenerated (C1).
Full cargo test green; clippy -D warnings + ruff clean.

D-246 (architecture): intra-class micro-habitat mosaic — a voxel_mosaic()
sub-chunk noise band modulates the D-228 axes into spatially-coherent,
relief-conditioned micro-habitats; palette keyed on surface-class ×
climate-biome × biosphere-register; five new D-228 axis values front-loaded
for determinism; within-patch believability metric in scope. Governs T-1084.
D-247 (content): habitable Reach worlds were alive before humans — the
settlement timeline forbids terraforming from dead rock. An authored per-world
chirality bit gates whether native life is edible (Compatible) or
inedible-but-inert (Mirror); "safe" and "edible" are decoupled; colonization
is ecological war that grows an Earth-crop footprint outward from settlements.

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.

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.

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.
clippy --all-targets -D warnings clean; 1580 lib tests + harnesses pass.

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.)
clippy --all-targets -D warnings clean; 1579 lib tests + the harness pass.

Lock the cascade's nature-half deliverable to "reads alive anywhere", not
"implemented" — the holy-grail objective surfaced by probing the generation
cascade.
- D-245 (architecture): the nature layers are accepted only when the
believability litmus passes at randomly-sampled locations across all
habitable bodies/seeds — multi-scale + never-repeating (macro identity,
meso non-stationarity, micro mosaic), coherence + non-stationarity +
intra-class variety + relief + climate-appropriateness, automated screen
under a human sign-off, budgeted -> strict. Q-123: threshold calibration.
- T-1079 (epic, north-star, DoD=D-245) + findings T-1080 (uniform climate
fields), T-1081 (near-zero relief), T-1082 (no water-body generator),
T-1084 (intra-class micro-habitat mosaic), and T-1083 (the repeatable
believability test protocol / D-245 enforcer).
- aliveness_probe bin: the exploratory probe that found these (runs the
deterministic cascade for a body+seed, reports per-district nature +
verdict). Seed for T-1083.

D-244 ratifies what the character architecture (D-159..D-164, runtime
CharacterVisualDescriptor compositing) and the Trellis env pipeline already implied
but no decision had recorded: the in-world view renders 3D objects directly; the only
flattened 2D content is textures + flat 2D artwork (paintings/flags/billboards/signage).
There is no per-object sprite layer.
Roots out the drift: the early-spike 3D->2D sprite pipeline (#541) and the sprite-centric
docs/assets/visual catalog were never cleaned out when the project went 3D, so the
2026-06-12 fable-ous audit read them as live and re-injected the dead sprite model into
T-1049/T-1050. Fix:
- docs/assets/visual/README.md + docs/assets/README.md re-scoped to 3D models + textures
+ flat artwork (dropped the sprites/tilesets-as-entities framing).
- /sprite-gen + renderer/README repurposed as the 2D-artwork generator (paintings/flags/
billboards/signage), not the in-world object format; legacy 4-direction object-sprite
mode flagged as retired.
- T-961/T-1049/T-1050 already held in backlog pending this.
