A river is sub-pixel at almost every Atlas scale (a 100 m channel against
Global's ~17.6 km per screen pixel), so drawing it to scale draws nothing.
The line becomes a symbol whose job is legibility: a fixed 5 px screen-space
stroke, contiguous through the river's own cell centres, never drawn over
water, and culled when too small to read.
The cull threshold derives from the stroke rather than being stipulated. A
mark reads as a line at roughly 3x its own width, so the minimum is 15 px of
on-screen length — and the kilometre thresholds then fall out of each rung's
scale: 264 km at Global, 2.8 km at Region, 28 m at District. A level-of-detail
ladder with no hand-tuned constants, which self-corrects if the width changes.
Measured on the visible extent, not total river length: a course crossing the
window always spans it and passes, so only a course wholly inside the view and
small is culled. Correct at both ends of the ladder, and no new wire field.
Records a tension that had to be resolved rather than split. Jeroen proposed a
flat 100 km cutoff, then noted that 5x5 px still reads as a dot and asked for
15-20. Those are incompatible: the km threshold depends only on the pixel
length, so 100 km implies ~6 px, which is dot-shaped at a 5 px stroke.
Admitting 100 km rivers AND keeping them line-shaped needs a ~2 px stroke.
Thick lines mean fewer rivers; thin lines mean more. Ruled for the bold stroke.
Client-side, and provably so: the cull is measured in screen pixels, and the
display ratio is a client-side viewport-dependent parameter that never reaches
a wire request or cache key, so the server cannot know how many pixels a
course occupies. Water-clipping needs nothing new either — the per-cell
classification is already in the adopted canvas.
Built on the 2026-07-27 measurement in D-258's amendment: 375 courses present,
458 of 518,400 pixels different. The rivers were not failing to render, they
were correctly beneath notice; the defect was drawing specks instead of
drawing properly or not at all.
T-1237 implements. T-1238 restores size-varying width as polish, deliberately
deferred — noting width and cull are coupled, since a thinner stroke lowers
its own visibility threshold.

Written one day after the record, on evidence, and it narrows D-258's scope.
The Rationale claimed hydrology 'was not derivable at all under the old
model'. Not true, and not true when written: layer1.rs already solves drainage
AND settled-equilibrium hydrology once per body, folds the filled surface into
TerrainAnalysis, and every rung bilinearly samples it. The code's own comment
names it — 'a coarse continuous primitive computed once, sampled fresh at
every rung, never re-solved', mechanism B, D-255(f). The pattern rung 0.5 was
invented to provide already existed. I inferred the claim from Region having
no rivers without reading the layer-1 pipeline.
What actually made Global flat was a stale sentinel zeroing its extent, giving
a 2x1 canvas. Once sized correctly Global reads as a world with no hydrology
work at all. Rivers there measured negligible: 375 courses present, 458 of
518,400 pixels changed versus courses-off, because at ~39.7 km/gridunit most
courses are shorter than one gridunit.
Survives: reliefmap-as-plurality, composition-on-descent, the conservation
invariant, and the lake-shore amendment — none depend on hydrology moving.
Weakened: the stored expanded layer and its D-227 carve-out, since the
compute-once-sample-everywhere mechanism it argued for is already shipped.
T-1211 and T-1212 flagged needs-refinement with the reasoning attached; the
measurement as scoped would have priced work that is not required.
The amendment also records why this survived review: the sizing fix's tests
called resolve_canvas_extent directly rather than the serve path, and the
capture goldens could not have caught it either since they never supplied a
body radius. Two verification layers, both green, neither looking at the thing.

Everything else from the pair session was either shipped or ticketed with its
rationale in git. These two were design decisions Jeroen made, living only in
a scratchpad under /tmp, one cleanup away from gone.
D-259 — ENCLOSED SETTLEMENTS. Open-air requires atmosphere == standard;
everything else is enclosed, as point locations on the Atlas with interiors
deferred to a separate generator and handled like embedded stations. Branch on
an explicit `enclosed` property rather than the atmosphere string, so enclosed
settlements on breathable worlds (hostile-biome posts, undersea, arcologies)
need no second code path. NULL defaults to enclosed, which fails safe.
The load-bearing claim is that D-220's density model is PHYSICALLY
INAPPLICABLE to a pressure vessel, not mistuned: it measures people per km2 of
footprint driven by utility cost per metre of street, so run airless it yields
1,500 ppl/km2 of open-air streets in vacuum. The handoff mechanism was already
planned — D-166's door boundary contract, where a dome's airlock IS that door.
Atmosphere keeps its full range for the surface-expedition layer; the binary
collapse applies to settlement layout only, and the record says so to stop the
collapse being read as atmosphere not mattering.
D-260 — GENERATOR SCOPE. Sol is encoded as Authored { deepest_rung: Global }
rather than excluded by convention. The DLC gate is a DEPTH, not a boolean, so
a Sol expansion changes one value instead of unpicking an exclusion. No new
wire status: "viewable at Global, no deeper" IS the existing rung-liveness
path. Sol art is an authored data canvas, not a finished image, so it rides
the existing wire and is drawn by the same map-art function as all 269
procedural bodies.
The hazard that made encoding necessary is recorded: systems.db still carries
terrain_reference rows for Sol bodies pointing at heightmaps deliberately never
baked, so a real Earth DEM dropped at that exact path would silently start
generating a procedural homeworld. The importer comment said Sol was excluded;
nothing enforced it.
Also files the last three parked items, which were likewise /tmp-only:
T-1233 tiled/interlaced map loading (workshop-sized D-255 revision, blocked in
spirit on the rung-0.5 cost numbers), T-1234 enumerate the flow tweaks the
fetch panel exposed but which were never written down, T-1235 zoom
discoverability — the person who specified wheel-only zoom could not find it.
T-1231 closed.

D-255 described a system that stopped existing this morning. It said a rung
fixes gridunit SPACING and that spacing is "never viewport-derived"; both are
now exactly backwards. Anything reading it — a refinement agent, a reviewer,
a future session — would have built against a fiction with no way to tell.
Records the inversion (a rung fixes EXTENT, the shorter viewport axis spans
one cell of that level, spacing falls out), Global moving from the body's
region grid to a viewport-sized 2:1 canvas, Region leaving the orbital derive
set, and the display-ratio band collapsing to a uniform 2x2.
Two corrections matter beyond bookkeeping.
D-255 justified Global's D-226(d) legality by it being COARSER than the region
grid. It is now finer — 40.8 km against 204.8 km. The conclusion survives,
since D-226(d) prohibits tile-level maps and caps at settlement/quarter
granularity and 40.8 km is twenty times coarser than a district, but the
premise is dead and nothing downstream should lean on it.
And the always-keep cache figure is invalidated. The "~8.85 MB across 267
bodies, trivially process-resident" number assumed ~18,073 cells per body; a
viewport-sized Global is 460,800 on a 1080p display, which is 25x — about
226 MB, and roughly 900 MB on a 4K display, with per-body derive going from
~16-21 ms to about half a second. An always-keep tier whose size scales with
the user's monitor is the wrong shape, which is an independent argument for
D-258: rung 0.5 is fixed-resolution and baked, and Global becomes a view of
it rather than a canvas retained in its own right.
Also records the two retired mechanisms (the S2 station-spacing floor,
cap_extent_to_body superseded by rung liveness) and states plainly that
Global is still broken — correctly sized now, but with no hydrology until
rung 0.5 lands. Region is eyeball-confirmed working.

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).

Jeroen, eyeballing the lakes: "they did not seem to run the same coastline
code as ocean does". Correct, in two separate ways.
The coastline warp was ocean-only. invent_primitives displaces the sample
through coast_warp_px before reading the ocean mask, but the lake test read
the UNWARPED position, so ocean coasts got invented bays and capes while lake
shores traced the bare elevation contour. It cannot be fixed by warping the
lake sample alone: a lake is where a filled surface sits above terrain, two
reads that must agree, so moving one and not the other puts water on
hillsides or holes inside lakes. Both surfaces move together in the rung-0.5
pass, or neither does.
And shore morphology was structurally unreachable at a lake edge. Every gate
keyed on ocean_fraction_q, which is always 0 in a lake basin because lakes sit
above sea level. Ruled: lakes get full shore morphology — cliffs, beaches,
deltas. Gates key on proximity to water, not to ocean. No new vocabulary
needed; MorphologyZone already carries Fjord, Delta, Wetland, CliffCoast and
DuneStrand.
The interesting part is what separates the sea-flavoured types, because it
isn't salinity. A delta builds land outward where the river deposits faster
than the water removes; an estuary is the inverse, a drowned valley widening
seaward. The discriminator is tidal energy: the microtidal Mediterranean is
ringed with deltas (Nile, Rhone, Po) despite being salt, while the macrotidal
Atlantic gives estuaries (Thames, Severn, Gironde). So lakes always resolve to
Delta — and so does a tideless sea, which an ocean-vs-lake switch would have
got wrong. Tidal energy governs TidalFlat too, so one derived quantity
replaces two stipulations and no "is it the ocean" branch survives.
Salinity is a property of water, not a landform, and is excluded from
morphology entirely. Derive it from below-sea-level connectivity if gameplay
ever needs it. Parked.

Every Atlas rung currently re-derives from the heightmap independently. D-258
inserts one deterministic whole-body layer between the baked inputs and the
ladder, and points every deeper rung at it instead of at the source files.
Two failures forced it. The Global rung was deriving a five-class hue map
while a per-body artefact labelled "clean color hypsometric render (display /
Atlas)" sat unused beside it. And hydrology was not derivable at all: flow is
a global solve, so no per-window derivation could produce a coherent water
system — Region carried no courses and lakes could not fill.
The record also fixes what the reliefmap IS. It is a plurality, not a
classification: each cell names the biome dominating ~38 km, a vote already
counted and discarded. So rung 0.5 un-summarises it rather than upscaling it,
which binds three consequences — biome edges are gradients never lines
(D-243's climate rule extended to biome), descending reveals composition
rather than sharpness, and invented detail must downsample back to the
summary it came from. That last one is the acceptance gate for any sub-biome
algorithm.
Rung 0.5 is a stored derived artefact and therefore a named carve-out from
D-227's derive-don't-store. The boundary is principled: D-227 governs what is
LOCALLY computable, where storage is pure cost. A whole-body flow solve is not
locally computable by construction — that is why it must exist — so storage
here buys correctness, not convenience. Everything below rung 0.5 stays
derive-don't-store.
Record precedes implementation; no code changes here. Complements the same
session's D-255 extent inversion, which governs how a canvas is sized rather
than what it is made of.

The surcharge is now COASTAL_ACCESS_SURCHARGE_HOPS_PER_RING=1 added
directly to length_cells (a pure hop count) — the old cost-unit
constant div_ceil'd through MIN_CELL_COST silently produced 4 hops per
ring, worst-case +24 (double the waypoint threshold) for physically
short edges; worst case is now 6. A formula-pinning test asserts both
the arithmetic and the constant. GJ251c's repro tightened to the
documented 2 edges. The always-land citation now points at the real
guarantee (features.rs::extract_attractors, D-209) — and checking the
D-211 Phase-4 synthetic-overflow path exposed a real gap: it has no
ocean-mask guard at all (T-1206 filed); documented, not papered over.
D-210 gains a dated amendment recording the surrogate-anchor-at-cost
carve-out and the relaxation-over-nudge adjudication. The bare 100
dependency dissolved with the unit fix. Edge counts on both repro
bodies verified unchanged (reachability was never affected).

ratio is viewport-fitted per body to the largest integer px/gridunit
that fits the legend-reserved viewport (floored at 1x1, letterbox

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

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

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

k<0 (revert-verification discovery). Plus the dangling cargo-fmt

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

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

Rivers/basins/attractors ride the existing whole-body layer1 field —
neither AtlasLayerResponse ceiling touched, no tagged-envelope

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

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.

D-227: records the two-tier driver model (body envelope from authored
params only, D-240 tilt exclusion upheld; position tier with fjord/
latitude/wetness/heterogeneity), the shared invent_primitives path,
the scatter floor-vs-ceiling reading, shoreline carving, and the
one-step-stale circularity ruling. D-239: Marine appended at
discriminant 6, morphology-derived verdict, airless precedence,
non-semantic Ord position.

Future implant apps/screens automatically extend the external app; per-app manifest bool (default true) locks out gameplay-dependent apps; in-game implant ignores the flag. Jeroen's suggested name availableInAtlasApp recorded with the rename rationale.

F1: T-1112 amendment touch-point list gains the ZoningType PartialOrd/Ord derive (mirroring DistrictType's T-994 precedent) so the dominant_zoning declaration-order tie-break is computable. F2: stale terminal-layer doc on AtlasLayerRequest.up_to corrected to Region. F3: believability cascade_for_body bumped to Region — harness mirrors production depth, invariant documented. F4: end-to-end dispatch coverage — populated-regions test asserts regions + second handle_atlas_request returns region_grid; no-params sibling asserts regions empty. Suites: layer_proxy 10, believability 4, gen_queue 8, cascade 10.

Aggregates-only layer keyed by city_id (QuarterWorldState carries no spatial position — QuarterId is a content-addressed hash; a 512m quarter is sub-pixel at planetary projection, so no outline geometry by construction). Five quantized fields (density_avg_pct, dominant_district_type, dominant_zoning, landmark_count, corridor_count); scaled-glyph encoding anchored on the L3 settlement dot (shape=dominant type, color=density ramp); landmark/corridor counts tooltip-only per the D-226(d) aggregate-stats ceiling; five wiring touch points named for the follow-up ticket.

Cleared stale STANDBY markers, swept dead DISCUSSION.md pointers, disambiguated overlapping personas, corrected asset-gen paths. Armed 7 discussion agents (gestalt/gore/mellanie/miri/nigel/ozzie/paula) with Bash so they can run the pql preamble. Integrated inigo into the roster + briefing (audio, standby). Removed tiger — localization dropped from scope (R-013). Part of T-1099.

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).

T-1095 fixed: template heads now receive the body's skin tone (same
treatment as seg_head) — _load_head passes tone.lit with a full-white
fallback mask through _attach_to_bone; without a mask sidecar the tint was
silently ignored, so untinted templates read grey against mid/dark tones.
Verified by lookbook render (head_001 on child, tone 6 — face matches arms).
Docs: the T-1088 locomotion design document committed to docs/design/ (the
sandbox code's 'design §' references now resolve in-repo); character-asset-
organization gains §11 Wardrobe Pipeline and sheds three stale claims (the
never-built indexed-greyscale mask plan, single-mask-per-asset for clothing,
the resolved multi-region open question); CHANGELOG carries the sidequest
entry; D-250 amended with the shipped cutaway-modes verdict (mode 2 default,
user-decided live).
Tickets: T-1088, T-1089, T-1095 closed; T-1096 filed (S9 live feel-tuning,
needs the user). The Fable-5 cascade exception is closed — the cascade
resumes at Phase 4 (T-750).
