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).

Lake edges rendered as hard step-edges while ocean coasts got multi-tone
transition bands: every coastal-transition morphology gate keys on
ocean_fraction_q, definitionally 0 inside a lake basin (hypothesis (b)
of the ticket; (a) disproven first — a shoreline-crossing sweep at
2048/512/128m plus a 10m fine sweep all land on the same continuous
crossing, so positional refinement was never broken). New
DistrictProfile.lake_margin_q (0-100 settled-hydrology depth band, from
the same bilinear filled/elevation pair the lake test already samples;
ceiling calibrated just above the observed p90 depth on GJ338Bd's 5,043
flooded cells), threaded through both derive paths onto
EncodedStepCanvas (serde-default for shape tolerance) and down the
client: protocol decode, terrain-layer plane, colorize shades Lake cells
by depth band instead of elev_q (bedrock-under-water, the wrong signal).
project.yaml 0.4.0 -> 0.4.1: the new wire field must invalidate the
client disk cache via its version tag (T-1183's D-192 mechanism).
Acceptance gates green with the new field (lossless round-trip,
cache-hit==cache-miss, every rung).

The D-225-discharging wire migration per D-255(c): a new
server/src/atlas/step_canvas.rs subsystem (six-rung StepCanvasRung
ladder — Global variable-extent rung 0 through Chunk 64m — the
StepCanvasRequest/StepCanvasResponse tagged envelope extending the
proven ShapeProbe discriminated-shape pattern, PNG-per-field dense +
MessagePack-native sparse encoding per the T-1179 measured table, and
both server cache tiers: the structurally keep-always GlobalTierCache
and the dual-axis StepCanvasCache with storage TTLs per rung and
SIM_STATE_TTL clock-bucket staleness per the D-227 amendment (1)
formula). Wired through bridge/{mod,tcp,local}.rs (sixth demux shape,
send_step_canvas_response mirroring the five existing senders),
gen_queue.rs (DeriveStepCanvas work item with per-connection-per-rung
coalescing, reusing the shared TerrainAnalysisCache), and plugin.rs
(serve/complete systems, lazy D-206 rung-0 population).
Acceptance gate (mandatory per D-227 amendment (3)):
tests/step_canvas_acceptance_gate.rs — cache-hit == cache-miss
byte-identical for every rung, lossless encode round-trips, cache
round-trips vs fresh derive, distinct-center sanity. 5/5 pass.
Station-spacing cap ADOPTED: course stations floored to District
spacing (2,048 m) at finer rungs — the S2-measured +38-87% chunk/block
course cost had zero display benefit at the same station density
(COURSE_STATION_SPACING_FLOOR_M).
Documented honest gaps, not shortcuts: settlement_id is a proximity
approximation (no footprint polygons exist yet); glaciation/flooded_q
sim-state planes are wire-shape-ready D-253 stubs; rung-0 uses signed
equator-anchored rows (the canonical D-256 core convention — T-1186's
wrong-latitude behavior applies unchanged and unfixed here, by
instruction).
Legacy district_window carrier byte-unchanged: window_derivation_golden
6/6 byte-identical, all district_window suites pass unmodified. Full
suite at implementation time: 2127 passed across 45 binaries.

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 apparent course-over-drawn-water contradiction resolved to two
reconciliation errors, neither in production: (1) the probe's first
reconstruction bypassed the request layer's wire clamp (Quarter n=32
serves as n=16 — build_district_window_layer trusts n verbatim by
doc); (2) the lead's capture read overestimated — the window frames
only the estuarine tail of a 213-station course (178 land stations
out of frame upstream; the visible water run is genuine Lake/
OpenOcean paint, RGB-verified against MORPHOLOGY_RGB_OPAQUE x
elevation-lightness) and the terminus sits ~240m from the painted
land->water crossing, not tens of km. Walk and paint agree at every
instrumented position (zero flip-flops across the monotonic 178-land/
35-water station sequence). New permanent test reproduces the exact
live window (real GJ380c + systems.db params, district (13195,-2383),
Quarter, clamped n=16; asserts 44 pts + Mouth as identity) and pins
the terminus-lands-in-painted-water invariant mechanism-agnostically;
revert-verified with an injected 500km positional slip. Probe
deleted. cargo test --lib 1878/1878.

The live acceptance question (Mouth flag apparently not surviving
crop) resolved to hypothesis (b): the terminus genuinely lay outside
both test windows — the Lendel mouth chord is ~108.5km, not the ~38km
estimated, so a District n=32 window centered on the cell OR the
midpoint misses the bisected waterline; a seaward-cell-centered
window provably ships Mouth. Hypothesis (a) — upstream-only crops
collapsing the flag — was FALSIFIED directly with a constructed
window (upstream anchor cut, true terminus in range -> Mouth ships;
crop reads only last_in). This test converts that probe into a
permanent pin with construction-sanity asserts, closing the blind
spot where the existing GJ1c acceptance test's bbox-derived window
always contains the whole course. Revert-verified: reintroducing a
first_in==0 requirement fails this test by name while the whole-
course test blindly passes — exactly the gap. Probe file deleted.

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
(additive, serde-default, parallel array; meaningful only at MOUTH
entries), captured in the same extraction pass; build_edges gives
Mouth edges the real one-D8-step chord. Permanent acceptance:
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).

A2 (river_course.rs): Stage A rung-independent valley-seeking control

penalty); Stage B rung-indexed perpendicular warp on GLOBAL arc-length

hard-truncate, sine taper to zero at anchors, amplitude min(8% chord,

6-iteration bisect; land-at-anchor probes one segment then None;
EdgeDrain never probes. A5: near_perennial_water point-to-segment
predicate (D-239 §8 governed bands 1-3m class-scaled) threaded through
both batch and window paths; Region always false; never touches
moisture_q. Discipline closed: dormant zoom-ladder bench run + numbers

determinism tests (overlapping-window byte-identity, cross-rung
amplitude bound, warp-stream cross-correlation r<0.3); goldens: window
sweep gained a verified course-bearing position (pure append), new
river_course golden at both rungs, believability verified unchanged.
Revert-verification discovered the pole-row branch is structurally
unreachable (flow_direction bounds-check) — the real edge-drain path

Tyre's I1 (his ruling: the cutoff's job is Nyquist, a property of the
RUNG): MIN_WL_BANDS_M's District band now derives from 2*DISTRICT_M
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
breaks the build for a deliberate human decision; golden_cutoffs_match_
the_scale_ladder now pins the District coupling too. I2: D-226
paraphrase replaced with cites to the T-1150 wire-contract note +
T-1162 refinement resolution (2), plus a self-found stale 2048m claim
fixed in the same comments. I4: golden extended with airless/dry
(ceiling_q==0 short-circuit) and volcanic-coast (ridged warp) body
rows via body_sweep_samples() — fixture regen verified 510 insertions,
0 deletions (existing rows byte-identical, purely appended). Q2 nit:
vegetation_invention module doc now states majority-preservation as
the coherence guarantee, not per-cell class stability (a boundary
cell's flip IS the clearing mechanism). Forward-contract for T-1156:

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
70% + cutoff-gated district/voxel texture at 30%) perturbing moisture_q
OUTPUT so precipitation/glaciation/vegetation shift as one world-fact;
wire format unchanged. MIN_WL_BANDS_M 5->6 (adds 1024m band).
Mid-implementation correction caught by tests: District's quantized
floor is 4096m (OCTAVE_WAVELENGTHS_M[3]), not 2x DISTRICT_M — the 8192m
and 4096m coast octaves are legitimately District-admitted enrichment;
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_
harness pattern, UPDATE_GOLDEN=1 regen) with structural guards pinning
Quarter/District divergence. Bench (zoom_ladder_bench, release): no
regression — all rungs at or below baseline (District c0 3.54->~3.0
us/cell, Quarter 2.10->1.77, orbital 1.48->1.42, n=6400 window
0.86->0.59 ms). Revert-verified voxel_relief cutoff exclusion. Server

noise-fragile pre-existing test properly fixed via 8-district

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.
R1 measured first: a capped Region tile through the real production path
(build_district_window_layer + T-1151 par_iter) at the 64x64 wire cap
costs 0.40-0.48ms — faster than the shipped district n=64 window, so
Jeroen's progressive capped-density tiling ruling is comfortably
interactive on-demand. Raw orbital derive ~0.9µs/cell (~2.3x faster than
full derive; region_baseline dominates, not invent_primitives).
R5 redesign: WindowGranularity enum (Quarter/District/Region), serde
named-variant per the RoadNodeKind precedent, spacing from D-243 scale::
constants — the single source of truth. Additive serde-default
window_granularity_v2 request field (None = legacy u32 path; v2 wins when
Some); DistrictWindowLayer.granularity_v2 always echoed. Legacy u32 echo
for Region uses reserved WINDOW_GRANULARITY_REGION_KEY = u32::MAX (never
a legal input) so the old slot cannot lie about aliasing. Cache and
coalescing keys carry the enum itself (Ord by declaration order, D-010).
n stays district-extent at every rung; Region's cell grid is a DIVISION
(round(n/100), min 1) with its own per-axis ceiling
DISTRICT_WINDOW_MAX_N_REGION=6400 and a bounded halving-loop clamp (no
closed form under the rounding division — the client mirror must
replicate the loop).
derive_orbital_at_metres: bilinear envelope reads + region_baseline
temperature, NO invent_primitives (proven by test — slope_q pinned 0),
routed through the shared build_district_profile classification tail so
the existing colorizer family renders orbital cells unchanged. R2
stepped-categorical behavior documented at the function, not implied.
Region aliasing + clamp/echo tests mirror the T-1150 discipline. 1813
lib tests green; clippy clean; fixture regenerated (254->278 bytes, new
echoed field).
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.
T-1151: build_district_window_layer dispatches one Rayon task per row
(pure derive_window_cell via derive_at_metres), scattered row-major into
the flat arrays; a cfg(test) serial path backs the bit-identical
parallel-vs-serial golden.
T-1150: serde-default window_granularity (1=district, 4=quarter) +
window_min_wl_m on AtlasLayerRequest — additive, no sixth demux shape,
old frames decode unchanged (tested). Quarter mode = full
reclassification at 512m spacing over the same world rect ((4n)x(4n)
cells); WIRE_CAP_CELLS=4096 enforces n*granularity <= cap (quarter
clamps n to 16, the design doc's worked example). Granularity + min_wl
key ALL five touch points: DistrictWindowLayer echo, server FIFO-256
cache key (now a 5-tuple), per-connection coalescing key, client
request codec (omitted-at-default wire fields), client LRU key.
Mandatory aliasing regressions on both ends: identical (body, center, n)
at granularity 1 vs 4 produce distinct cache entries and correct
per-granularity payload shapes (server, 3-thread queue to avoid the
AnalyzeBody thread contention found while writing it) and distinct
client cache keys (gdUnit). Replay fixture regenerated — the layer
struct grew two echoed fields (231->254 bytes, content verified).
Client requests stay district-granularity by default — quarter requests
arrive with T-1153's rung selection.
Hoshe's finding: the flag introduced so auto-fit never fights a manual
view had zero coverage on exactly that branch. Two tests drive the
REAL _gui_input path (synthetic drag), then fire NOTIFICATION_RESIZED:
user-adjusted view survives a resize untouched (zoom AND offset);
an unadjusted view re-fits to the new viewport. 52/52.
Non-blocking doc note also taken: layer_proxy's normalization comment
claimed the twins would otherwise 'coalesce independently' — the
coalescing key is (ConnectionId, body_id) and never carried center;
rewritten to say what normalization actually buys on that path (the
work item derives and echoes the canonical center).

The server clamped window_n but trusted window_center — the letterbox
bug's impossible (12276, 3021) was derived at clamped-garbage latitude
and CACHED under its raw key. normalize_window_center mirrors the
forward map exactly (column rem_euclid against the body's district
circumference, row clamped to +/-half-meridian; constants from
scale::DISTRICT_M, no new magic numbers; no-radius test bodies
identity). Applied in serve_district_window BEFORE the window-cache
key and the coalescing key, so an insane request and its sane twin
share one entry — proven end-to-end with the literal bug values on a
500km fixture body resolving to canonical (4, 383), byte-identical.
Echo contract: DistrictWindowLayer.center now carries the NORMALIZED
value. Reconciled by design with the client half in this same branch —
the client canonicalizes before sending (bit-identical math, posmod ==
rem_euclid verified), so request and echo agree from the first
round-trip; server normalization is defense-in-depth for buggy or
modified clients.

C1 (Tyre): the DeriveWindow branch re-ran the ~45ms run_layer1 for
EVERY uncached window — the dominant pan-around-one-body path paid
~52ms per new window while the doc claimed one-time-per-body.
TerrainAnalysisCache: private per-body LRU (capacity 8, ~2MB/entry,
true access-recency eviction — which body the player keeps panning IS
a recency signal) held as Arc<Mutex<>> on GenerationQueue itself, the
in_flight field pattern, because run_work_item executes on a Rayon
worker where the main-thread caches are unreachable. DeriveWindow now
calls get_or_derive; the variant doc states the real model (first
window per body pays ~45ms once; subsequent windows any center/n hit
the LRU; eviction re-pays). End-to-end test proves two windows on one
body via two connections share exactly one cache entry.
C3 (Tyre): the determinism test reused one TerrainAnalysis — proving
the packer, not the derivation. New test runs run_layer1 twice
independently, asserts field-by-field analysis agreement, then
byte-identical packed windows end to end (D-227 save-critical proof).
Packer-only test kept alongside.

AtlasLayerRequest gains window_center/window_n (serde-default, absent
= whole-body, wire back-compat; demux untouched — up_to stays the
discriminator). DistrictWindowLayer echoes center/n + six parallel
arrays (morphology, elev_q, temp_dc i16 with the region sentinel,
moisture_q, vegetation incl Marine=6, glaciation).
Serving per the amendment's binding model: NEVER inline —
GenWorkItem::DeriveWindow rides the Rayon queue, completion drain
caches into DistrictWindowCache (bounded FIFO 256; no staleness by
D-227 purity, capacity bound only), serve_district_window polls the
cache and returns Pending-shaped None until derived. Per-connection
coalescing: submit_window supersedes a still-pending item for the
same (ConnectionId, body) — the surviving item is the newer one,
proven by dedicated tests.
TerrainAnalysis decision (option b, numbers in ticket/PR): re-derive
via run_layer1 in the DeriveWindow branch rather than caching ~1.5MB
x 50 LRU slots (~100MB permanent, the exact D-203 bloat T-1044's own
text guarded against); ~45ms one-time on the Rayon path, invisible to
the tick thread. T-1044 confirmed within-cascade-only (cascade.rs:358
still drops the analysis before BodyWorldState) — the fork was open.
Window derive loop promoted from aliveness_probe::render_window_panels;
determinism promoted from probe-only proof to a real test (two passes
byte-identical). New fixture atlas_response_ready_with_window
exercises all six arrays incl. the airless sentinel and Marine; three
existing fixtures gain district_window: None. Server clamps window_n
to 1..=DISTRICT_WINDOW_MAX_N=64 (never trust the wire).
1774/1774 lib + 19/19 bridge_tcp green.

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.

ZoningType gains PartialOrd/Ord (DistrictType T-994 mirror) for the
dominant_zoning declaration-order tie-break. layer_proxy:
QuarterFootprintEntry/QuarterFootprintLayer (BTreeMap keyed by
city_id; density_avg_pct floor-mean, dominant_* mode with
declaration-order tie-break, landmark/corridor counts) +
build_quarter_footprint_layer gated None on empty state.quarters;
sixth AtlasLayerResponse field wired into all construction sites;
growth-ceiling doc updated to say the whole-body budget is consumed
(what carries a seventh is T-1124's design, resolved in the same
branch's amendment). Placements whose derived Layer4Quarter id is not
yet in state.quarters are SKIPPED (skeleton gen is async Low-priority
— entries may be a proper subset; client decodes defensively). Stale
TODO(#957) removed (premise predates T-957 landing).
Tie-break bug caught by its own test: Iterator::max_by_key over a
BTreeMap returns the LAST max on ties — backwards from
declaration-order-first; replaced with an explicit forward walk that
replaces only on strictly-greater count.
gen_fixtures: populated RegionGridLayer (T-1118 replay coverage) +
QuarterFootprintLayer literals in the ready fixture; msgpack fixtures
regenerated via make fixtures. Note: landmark_count is inert on real
data today (BlockSkeleton.landmark hardcoded None until landmark
placement lands); fixtures use non-zero counts to exercise the logic.
5 new unit tests + populated round-trip; atlas:: 549 green.

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.

CascadeLayer::Region appended per the enum's append-only Ord rule (depends only on seed/body_params/heightmap dims — documented); BodyWorldState.regions BTreeMap per the districts precedent; RegionGridLayer dense row-major all-integer encoding (season/weather repr(u8) discriminants, mean_temp deci-degC i16 with i16::MIN airless sentinel, moisture_q u8); build_region_grid mirrors build_district_grid; protocol.gd region_grid passthrough (visual overlay deliberately out of scope); wire fixtures regenerated via make fixtures. atlas:: suite 507 green.

is_standalone_hq threaded through CityRecord/CityPlacement via corporations LEFT JOIN (both readers); hubs = top-cap by population among non-HQ settlements (HUB_SPACING_DIAG_PX=64, HUB_CAP_MIN=6); exact-name collapse keeping lowest city_id with loud warn; nearest-point-on-polyline snap (SNAP_MAX_PX=8) with Junction edge-split preserving from<to via norm_edge, else A*-spur to nearest hub; FoundingOrientation::RailHeadFacing{bearing_degrees} assigned at degree>=3 junctions (octant bearing toward dominant incident edge), consumed by skeleton_gen railhead_edge() through the D-234b flush-frontage machinery; believability reader now honours baked settlement_class (stale hardcode since T-1075). 11 new targeted tests; existing suites green.

H1 demux: ShapeProbe defensive multi-shape rejection (union frames now Err, not first-match; +2 tests) and doc claim made honest. H2/T1 SystemIndex.reset_test_state() folded into SimBridge.reset_test_state() (load() inline per autoload rule) + has_pending_request() accessor. H3 no-op tests now assert the replay flag both directions. H4 retry test actually ingests a failure and asserts the retry semantic. H5 error fixture uses the normalized status string. H6 bridge_tcp e2e sends all five frame shapes over real TCP (star-map + city-names buffers asserted). H7 positive replay-on-CONNECTED test via the test_local_bridge test-mode-flip precedent (stub bridge captures + decodes the request bytes). H8/T2 stale PLACEHOLDER doc replaced with the confirmed contract. H9 is_capital doc matches the COALESCE reality. T-r1 demux ceiling written down (next shape = tagged envelope). T-r2 AtlasLayerResponse governance ceiling comment. Lead item: the four cargo-fmt-formatted files from the gate round are now committed (layer_proxy/plugin/bridge-mod/main). H10 note for the record: the 13 snapshot_*.msgpack fixtures in commit 845737617 were regenerated because they were stale against their own generator (pre-existing version-key removal) — verified harmless, no client reads that key.

T-960: RoadGraphLayer (L2 edges/junctions, MaintenanceAuthority, rail flag, named routes) + SettlementLayer (name/position/size-class/is_capital/is_port from T-955 placements) as new Option fields on AtlasLayerResponse — T-1046 precedent; layer_proxy doc comment corrected (cascade runs through RoadGraph, client up_to ignored). T-949: new StarMapRequest/StarMapResponse (raw JSON passthrough of the star_map_data.json bake) + CityNamesRequest/CityNamesResponse (atlas_city_names via CityContextReader) with defense-in-depth Sol exclusion (GJ-0 system id OR settlement_wave='origin', D-236). Inbound demux extended with mandatory boolean discriminator fields (serde ignores unknown fields — optional-shape sniffing would be ambiguous); AtlasLayerRequest unchanged. SimBridge trait +2 methods, implemented on TcpBridge + LocalBridge. CityPlacement/CityRecord gained name/population/is_capital (BodyWorldState cache-hit path stays DB-free). ~30 new unit tests incl. demux disambiguation + Sol branches; gen_fixtures extended for road/settlement samples.

T-1044: run_layer1 now returns TerrainAnalysis (carried transiently on
CascadeSnapshot, dropped after the district + road-graph passes), eliminating the
redundant per-body drainage::analyze + TerrainAnalysis::analyze re-run flagged by
PERF/TODO(T-1044). Not persisted on the LRU-cached state (D-203/T-1048 size concern).
T-1047: basin_direction is now derived from the real D8 thalweg. run_layer1
aggregates a per-district dominant D8 direction from the live fdir grid (carried
transiently on DrainageResult), threaded via Layer1Output.district_basin_dirs ->
derive_all_districts -> DistrictProfile.basin_direction; derive_chunk_context reads
it directly. Removed the false derive_basin_direction (it branched on ocean_fraction_q
then read seed bits despite a doc comment claiming an elev_q/slope_q D8 proxy) +
corrected the module contract. D-239 §8 (D8 thalweg) now actually honoured.
1559 tests pass; golden byte-identical (district_basin_dirs is #[serde(skip)], transient).

Server half of wiring the derived tier into production. The D-225 proxy
(AtlasLayerResponse) carried only Layer1Output, so the Atlas could not show the
DistrictProfile tier that the cascade derives. Adds DistrictGridLayer (cols/rows
+ row-major MorphologyZone discriminants + elev_q for relief shading) and
build_district_grid(), populated on a cache hit. Because the response is
rmp_serde msgpack end-to-end, the new field reaches the client automatically.
This is the planetary-scale coarse grid (the Atlas map view); the on-demand 2km
derive_district (T-1077) is for in-world Phase 5, not the map. MorphologyZone
gains Copy (fieldless repr(u8) enum; additive).
Next: client decode (protocol.gd) + the D-226 generation overlay in the Atlas
viewer.

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.

New deterministic cascade layer (CascadeLayer::RoadGraph) building the
transport topology between Layer-3 settlement placements, stored on
BodyWorldState.road_graph (session-cached, never serialized).
- MST force-connect (strict Kruskal over squared distance) + secondary
links across a 30-60% body-scale band where the MST detours >1.5x.
- A* over the Layer-1 terrain-cost field on a coarse ~64-wide routing grid:
ocean/lake impassable, river corridors 1/2 cost, slope >=35deg (D-210
roughness ~0.7) 10x, else the D-210 terrain_modification_cost. Columns
wrap (equirectangular); integer costs + index tie-break keep A*
deterministic.
- MaintenanceAuthority per edge (new generator.rs enum) from endpoint
political archetypes + haul length; waypoint nodes at long-edge midpoints;
named-route identity join (designed-for, pool empty post-D-223); junction
detection (high_connectivity_junctions, degree>=3).
Wired into the cascade (gen_queue requests CascadeLayer::RoadGraph). Adds
Copy to PoliticalArchetype. 10 road_graph unit tests + a cascade e2e test;
full suite + clippy --all-targets -D warnings green.
Deferred to T-1076 (gated on the D-242 settlement model): the RailHeadFacing
junction pass (needs a D-213 FoundingOrientation amendment + Layer-4 handling)
and the hub-selection refinement (needs baked population/specialization).

The D-239 carrier layer (T-1023/1024/1026) only ran in tests because every
production AnalyzeBody enqueue passed body_params: None. Wire the real path:
- New BodyParamsReader (server/src/atlas/body_params_reader.rs): read-only
systems.db reader, joins bodies -> star_systems (LEFT JOIN) for the climate/
tectonic inputs. SQL verified against systems-schema.sql. All fields Option,
NULLs handled; tectonic_activity absent from schema -> None (derives from
planet_class). 5 unit tests.
- layer_proxy.rs: on cache miss, read the body's params and pass
Some(Box::new(..)). On read error, warn + fall back to None (cascade stops at
Settlement, no panic) — graceful degradation.
- plugin.rs / main.rs: register BodyParamsReaderResource (CityContextReader
pattern) and thread it through serve_atlas_requests.
BodyWorldState.regions now populates for real bodies in the D-206 background
pass. End-to-end tests cover wired (regions populated) + unwired (empty) paths.
cargo test 1504 pass, clippy -D warnings clean, fmt clean.

First foundation slice of the Atlas-to-tile derivation model (epic T-974),
building the carrier layer ahead of its T-1027+ consumers.
T-1026 — Anti-squaring domain warp (D-239 §4): stateless pure
fn(seed,body_id,pos)->(f64,f64), ±8m, f64 to the final voxel then as-i32
truncation for IEEE-754 cross-target determinism. New domain_warp.rs,
SeedDomain::DomainWarp; golden-vector + cross-thread tests. Position math
only — D-010 integer discipline preserved downstream. Marked dead_code
until the T-1028 VoxelColumn pipeline consumes it.
T-1023 — RegionProfile carrier (D-239 §1,§10): new RegionProfile +
TectonicClass/GlaciationGrade/PrecipitationClass enums + BodyParams; derived
per-region river_threshold replacing the global 200 for tile consumers.
regions: BTreeMap on BodyWorldState, populated via the cascade's new
RegionProfile layer (runs when body_params is Some, else falls back to
Settlement). D-010 integer discipline, BTree ordering.
T-1024 — District climate primitives (D-239 §2): nullable temperature_c +
moisture on RegionProfile, mean-annual scalar (no clock dep; dynamic branch
deferred to Q-105). Hybrid inputs — new bodies.axial_tilt_deg column imported
from planet-gen body-defs (populate_axial_tilt_deg, 2611 bodies), luminosity
and orbital distance derived at runtime; greenhouse + diurnal-swing tables in
source-canonical climate_constants.toml. D-239 implementation note added.
cargo test: 1498 passed, 0 failed. clippy clean (pre-existing
large_enum_variant only). make check-systems-db: stamp fresh.

Derive and store each placed settlement's spatial character on top of the
#955 placement (D-212/213/214/215). Derivation is pure + integer-deterministic
(D-010); the cascade stays DB-free (D-225) — the enqueuer pre-resolves the
body's system faction onto the work item, like #955's settlements.
- TerritorialStatus (D-212): mapped from the authored dominant_faction
(territorial_status_from_faction). Adds an AutonomistHeld variant for the
Compact of Westphalia (self-governing bloc that rejects Assembly authority —
neither Commission, Corp, Contested, nor truly Frontier). Grounded in
wiki/factions/. Stored per-province on DrainageBasin.territorial_status
(uniform per body for now; forward-compatible for per-province faction data).
- PoliticalArchetype (D-214): political_archetype(status, role), status takes
precedence over economic_role.
- ArrangementPattern (D-215): new 5-variant enum + arrangement_pattern(); the
block-adjacency *enforcement* stays deferred to the Quarter-skeleton gen (#957)
— this only derives + stores which pattern applies.
- FoundingOrientation (D-213): existing fn extended with a seed-derived Free
bearing so pioneer/open-terrain grids vary per seed.
Wiring: dominant_faction threaded through CityContextReader
(read_body_dominant_faction) → atlas proxy (cache-miss read) → AnalyzeBody work
item → run_cascade → run_layer3/match_cities. Enrichment stored on CityPlacement
(political_archetype, arrangement_pattern, founding_orientation).

D-222 renamed the 512m generation cell from District to Quarter (District
is now a new 2048m tier above it). Align the generation skeleton code to
the canonical vocabulary. Pure naming — no behavior change; all 1296 lib
tests + integration tests pass unchanged.
Renamed (spatial-cell identifiers):
- DistrictSkeleton → QuarterSkeleton, DistrictWorldState → QuarterWorldState
- DistrictId → QuarterId, DistrictContext/DistrictBoundaries → Quarter*
- field district_id → quarter_id, district_type → quarter_type
- BodyWorldState.districts map → .quarters
- generate_skeleton → generate_quarter_skeleton
Deliberately left as-is (these name functional ZONING, not the spatial
tier — orthogonal to D-222): DistrictType, DistrictLayoutMode, the
district_mix module (DistrictMix/compute_district_mix), and the
GenWorkItem::GenerateSkeleton / GenCompletion::SkeletonGenerated variants.
Also aligned the perception "sim tile" → "subtile" vocabulary (D-222:
Subtile = 0.5m) in decisions/perception.md and the generation-cascade code
comments. Historical D-066/D-094/D-201/D-220 decision bodies keep their
existing D-222 amendment notes (not rewritten in place); the public
max_offset_sim_tiles fn name is unchanged.

Address the doc/test-correctness items from PR #149 review:
- cascade.rs: Layer 3 is RNG-free (pure fn of attractors+cities); it does
not consume the carried SeedChain. Corrected the "first RNG-using layer"
claims on the module doc and the Settlement variant (Hoshe H3).
- cascade.rs: layers_are_ordered now also asserts Topography < Settlement,
pinning the invariant the up_to >= Settlement guards rely on (Tyre T2).
- features.rs: strength is an integer 0-100 (quantized at extraction), not
f32, and consumers that rank by it use the integer value (Hoshe H2).
- layer_proxy.rs: AtlasLayerRequest.up_to is not yet honored — run_work_item
runs through Settlement unconditionally; per-request depth deferred to
#1021 (Tyre T1).

Wire the existing D-211 attractor-matching engine into the live
generation cascade so settlements are placed in-game, not just in tests.
- CityContextReader::read_body_settlements reads a body's settlements
from atlas_city_names (ordered by id for determinism). NULL
settlement_class defaults to PopulationBudget, not NameLocked: the
class is NULL until placement runs, and NameLocked would force every
settlement Tier-A in match_cities and collapse population tiering
(D-211). NULL economic_role falls back to residential.
- The AnalyzeBody work item carries the body's Vec<CityRecord>, and
run_work_item now runs up_to Settlement (was Topography). A body with
no settlements yields empty placements at negligible cost.
- The atlas layer proxy reads settlements on a cache miss and pins them
onto the work item, keeping the Rayon task DB-free (D-225). A read
failure is non-fatal: log and place no cities (Layer 1 still runs).
Threaded through a new CityContextReaderResource Bevy resource opened
in main.rs, mirroring BodySourceResolverResource.

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.

Define the type-definition layer the Phase-4 fill-seam tickets depend on
(D-229/D-230/D-231/D-232/D-233), compiling with stubs/defaults; behavior
logic lands in #982-985/#998.
- New types in generator.rs: BuildingPropertyTag, FloorExtent +
FloorHeightProfile (floor_at_voxel_z/voxel_range_for_floor, resolves
Q-104), BuildingEntryClass, ConstructionEra, ZoneTypeId, MorphologyZone,
BulkClass(5), ProductionUbiquity, DoorSpec, InteriorDescriptor,
DistrictWorldState.
- Rename spatial AccessTier -> ZoneAccessTier to free the name for the new
per-building BuildingEntryClass.
- CityGenerationContext: +morphology_zone, +trait_selection,
+dominant_bulk_class, +dominant_production_ubiquity.
- BodyWorldState: +districts (DistrictWorldState w/ block_tags).
- GenCompletion::SkeletonGenerated carries body_id + DistrictWorldState;
plugin handler inserts into BodyWorldState.districts.
- Add smallvec as a direct dep (DoorSpec list stays Vec for now, TODO).
cargo check --all-targets / clippy clean; 1259 lib tests pass.

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.

handle_atlas_request: cache hit -> serialize Layer1Output, reply Ready; miss ->
