jpmschweitzerandClaude Fable 5 ff98a10d42 feat(simulation): T-1156 — quantized river_class on RiverNetwork (trunk/tributary/stream)
The one additive server change of wave 1 per Tyre's carrier ruling:
river_class: Vec<u8> parallel to river_cells, serde-default-safe, no
new wire field. Log-scaled binning between RIVER_THRESHOLD and the
RIVER-RESTRICTED max accumulation (max over cells passing the is_river
elevation filter — NOT the grid-wide max, which peaks past the
coastline on wet large-ocean bodies and would starve the trunk class
exactly where Araminta's District-shows-trunk-only table needs it;
caught in lead review of round 1, fixed round 2). Log not linear
because accumulation grows combinatorially downstream. By construction
every body with rivers has trunk cells — pinned by a non-synthetic
regression on the committed GJ1c heightmap at the golden's exact
downsample. cascade_layer1.json regenerated: every pre-existing field
byte-identical (python-verified), only the new river_class arrays
added — GJ1c distribution stream 72 / tributary 18 / trunk 3.
drainage 16/16 (+10), layer1 3/3, layer_proxy 50/50, build --tests
clean; revert-verified (non-monotonic binning fails the monotonicity
test by name).

jpmschweitzerandClaude Fable 5 3368891976 fix(simulation): PR #194 review round — rung-floor dependency direction, golden body coverage, doc honesty
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:
0x5EED_C0DE promoted to named WINDOW_RELIEF_SALT const. 158 focused
tests green; cargo check --tests clean.

jpmschweitzerandClaude Fable 5 5cb63b6867 feat(simulation): T-1162 — invention octaves into the Atlas window path (coast crinkle, quarter relief, vegetation patchiness)
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
lib 1840 passed; new module 11 tests; district_profile 84 (+6, 1
noise-fragile pre-existing test properly fixed via 8-district
latitude-band averaging).

jpmschweitzer da15261276 fix(client): PR #192 review round — per-rung legend, Region coalescing + clamp boundary tests, halving-loop honesty
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.

jpmschweitzer d356b09926 feat(simulation): T-1152 server half — WindowGranularity enum, derive_orbital_at_metres, Region rung on the same carrier
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).

jpmschweitzer 0159a63cc2 fix(simulation): PR #191 review round — n-clamp mirror, min_wl band quantization, coalescing coverage, fixture consumer
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.

jpmschweitzer 3e87fd5b4f feat(simulation): T-1151 window par_iter + T-1150 granularity carrier (five touch points + aliasing tests)
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.

jpmschweitzer afff859a2c feat(simulation): T-1149 derive_at_metres extraction + min_wavelength octave cutoff
Extract derive_district's fractional-metres interior into the metres-
addressable derive_at_metres(seed, body, params, ta, wx, wy, climate,
min_wavelength_m) — the zoom ladder's keystone (design doc §8 step 1).
derive_district is now a thin DistrictPos-quantizing wrapper calling it
with cutoff 0.0; all four golden/believability/derivation harnesses pass
byte-identical.

enveloped_fbm/terrain_detail/voxel_relief gain min_wavelength_m: octaves
below the cutoff are hard-truncated (amp still advances so surviving
octaves keep relative weight; norm==0 guarded). Amplitude-fade-near-
cutoff is documented as a seam, not built — the pop-risk A/B needs the
client ladder (T-1153). Cutoff 0.0 is bit-identical to pre-change
output, asserted by test.

Measured (release, 4096-cell sweeps, zoom_ladder_bench.rs): district
spacing 1.200µs/cell (cutoff 0) / 1.201µs (cutoff 2048m — all octaves
survive, plumbing check); quarter spacing 1.165µs/cell (cutoff 512m).
Matches the design doc's ~1.2-1.4µs/cell release estimate.

jpmschweitzerandClaude Fable 5 7ce6cc08fd test(ui): pin the _user_adjusted resize guard both ways; fix coalescing doc overstatement (PR #188 review)
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).

jpmschweitzerandClaude Fable 5 4a65bb210d fix(simulation): normalize window_center before cache and coalescing keys (T-1142 server half)
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.

6 new tests incl. the twin-cache proof and the echo pin; atlas::
570/570, lib 1784/1784, timing-sensitive tests 3x stable.

jpmschweitzerandClaude Fable 5 df33e9f2fb fix(simulation): per-body TerrainAnalysis LRU + full-path determinism test (PR #187 C1/C3)
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.

jpmschweitzerandClaude Fable 5 172ce124c8 feat(simulation): T-1137 windowed district layer — queue-served, coalesced, determinism-tested (D-226 T-1124 SS1-SS4)
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.

jpmschweitzerandClaude Fable 5 c20c175af1 docs(meta): D-226 T-1124 amendment — PR #185 Troblum findings (windowed-family ceiling, queue-based serving, comment reconciliation)
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.

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

jpmschweitzerandClaude Fable 5 2509624577 fix(engine): resolve systems.db exe-anchored, not cwd-relative — spawn-mode DB access
PathBuf::from("data/systems.db") was cwd-relative, and a spawned
server inherits GODOT's cwd — which is client/ (Godot's --path client
chdirs), so CultureResolver, CityContextReader, BodySourceResolver and
BrowseReader all silently failed in every make atlas / make game
spawn. Wave 1 masked it: the star map serves from star_map_data.json,
so 'renders 301 systems' never touched the DB; T-1133's browser was
the first DB-backed consumer to hit it live (Stig, /proc/PID/cwd).

resolve_systems_db_path(): exe-anchored <exe_dir>/../../data/systems.db
first (cwd-independent — the actual fix), then cwd-relative
data/systems.db (cd server && cargo run), then server/data/systems.db
(repo-root invocations); first existing candidate wins, info-logged.
Pure systems_db_candidates() split out as the testable seam (5 unit
tests — incl. pinning Path::parent() of a bare filename = Some(""),
not None). world_root now derives from the resolved ABSOLUTE path so
its ancestors().nth(3) arithmetic holds unconditionally instead of
silently falling back to ".." when canonicalize failed.

Verified all three launch styles; make atlas spawn shows 5 reader fds
open on server/data/systems.db via /proc/PID/fd.

jpmschweitzerandClaude Fable 5 d48d72fd31 feat(engine): T-1131 browse data proxy — six entity kinds, index+detail, one wire envelope (D-254 SS4)
browse_reader.rs: BrowseReader on the CityContextReader::open() pattern
— six index + six detail reads against systems.db (bodies filterable by
containing system; system/corporation/commodity details fold their join
partners). browse_proxy.rs: BrowseRequest{browse, kind, query} /
BrowseResponse{kind, status, index, detail} wire types + dispatcher;
BrowseIndexRow{id, primary, secondary} generic across kinds;
BrowseDetail a per-kind enum of field-exhaustive structs.

Demux: Inbound::BrowseRequest is the FIFTH map shape — deliberately the
last; the doc's four-shape ceiling is re-pinned at five with rationale
(six kinds x two forms folded into ONE envelope whose internal enums
pick sub-behavior, the AtlasLayerRequest.up_to precedent, instead of
twelve top-level shapes) and a hard rule that a sixth shape must
migrate to the D-225 tagged-envelope framing. Served for BOTH roles,

jpmschweitzerandClaude Fable 5 ddc3d39d09 feat(engine): T-1130 reader connections — role-gated multi-connection bridge (D-254 SS1/SS2)
ConnectionRole (Player|Reader, serde-default Player for wire back-compat;
shaped for a future TradingReader) on StartupMessage. BridgeResource
rewritten as 0-1 Player + 0-N Readers with ConnectionId; per-tick
accept_new_connections loop replaces the single blocking accept (the
listener is cloned non-blocking into ConnectionListener). First
connection installs per startup.role — spawn-mode Readers are often the
only connection a server gets.

Permitted-message matrix: readers may handshake and issue
Atlas/StarMap/CityNames requests (responses connection-tagged, own
requests only); PlayerInput from a reader is dropped with a strike
(disconnect at 3); ObserverSnapshot has no reader-facing path at all.
Shutdown scope: only a PLAYER send failure flips ServerRunning —
reader-only servers idle with the snapshot queued; reader disconnects
never kill the session.

Deliberately out of scope, documented at the call site: character spawn
stays in monolithic world-setup (reader-first servers carry an inert
unpiloted PlayerCharacter); no total-reader-count cap (per-reader frame
cap only, loopback-only scope).

6 new bridge_tcp integration tests; layer3 subprocess test exercises the
accept-loop end to end.

aliveness_probe --render gains a 6th glaciation panel; glaciated
districts get an ice tint keyed on GlaciationGrade, and Marine
vegetation renders [0,96,172] — distinct from the morphology water
tones so district-carrier vs voxel-generator disagreement stays

jpmschweitzerandClaude Fable 5 fef422bf01 feat(simulation): T-1125/T-1126 coastline invention — two-tier character model, shared invent_primitives, Marine vegetation
T-1125: new atlas/coast_invention.rs — BodyCoastEnvelope (tier 1: erosion
maturity derived hydro×atmo, tectonic energy; D-240 stands, no orbital
inputs) + coast_character_at (tier 2: latitude, glaciation fjord response,
local wetness, seeded 100-400 km heterogeneity field). C1 multi-octave
warp ~16-262 km, sub-pixel cap 0.75 px, salted stream isolated from
terrain scatter and climate edge-fuzz.

district_profile: shared invent_primitives front-half (warped envelope
sampling + slope-independent scatter floor + shoreline carving) wired
into BOTH derive_district and derive_district_profile — the batch path's
scatter-free area-mean aggregate is replaced by an invented centre-point
sample of the same continuous field, making silent path divergence
structurally impossible.

T-1126: VegetationClass::Marine appended at discriminant 6, verdict
morphology-derived (open_water from OpenOcean|Lake — no fourth ocean
threshold); airless precedence preserved. voxel.rs exhaustive-match arm
documented unreachable (WaterBody owns ocean districts).

Determinism proven: 5/5 panels byte-identical across passes AND cross-process (md5s reproduced in a fresh run). ~8us/district debug. First-ever look at the district layer produced the T-1125/T-1126/T-1127 findings (D-227 seam ends at ~500km; ocean-blind vegetation; unrendered glaciation).

3-step era-free derivation (visual_bundle filter -> zone-bias weighted
pick -> density->setback), color seed-sampled within the register band.
Resolved at GenerateSkeleton plan time (T-994 precedent), frozen on
BuildingPropertyTag; FillChunk only reads it. Four append-only
integer-discriminant enums (WallMaterial/RoofForm/FacadeRhythm/
StreetSurface), unknown token -> axis Generic + warn. trait_catalog_reader
now parses visual_bundle + the two new tables (OnceLock-cached).
New SeedDomain::TraitExterior (per-axis sub-chains — no cross-field
correlation).

T-959 — FillChunk reads the frozen exterior tag: wall_material/roof_form
onto Wall/Roof shell voxels (FilledChunk.surface_material). Additive,
ShellVoxel untouched, all shell tests pass. (Interstitial-fill-from-setback
split to T-1098 — needs a FillChunk block-metadata + geometry design pass;
nothing consumes FillChunk until Phase 5.)

D-233 bulk-driven: bulk-industry blocks' non-roofed remainder tags as built
economic infrastructure, not generic open space.

jpmschweitzerandClaude Fable 5 90655382eb feat(simulation): D-232 three-phase trait draw + deviation/swerve system (T-994, T-1003)
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

jpmschweitzerandClaude Opus 4.8 895bb83bad fix(simulation): unify C1 climate gate across Wetland+Forest+Grassland (PR #172 N1)
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.

The mosaic palette gains a climate-biome dimension for the Grassland surface-class:
savanna / temperate / boreal / tundra now read distinctly rather than collapsing to
one biome-blind palette (the D-246 biome-awareness fix).

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

v1 scope (D-246-faithful): modulates vegetation + water only, in the vegetated
classes (Wetland/Forest/Grassland), so the D-239 §8 lithology law is untouched;
water is gated on the T-1040 has_active_channel hydrology rule. Material variants
(hardpan/scree) and the extreme classes are a §8-aware follow-up; the biome-aware
palette variants (T-1085 vocab) extend the baseline before generation.

Goldens regenerated (believability + derivation). Full server suite green.

jpmschweitzerandClaude Opus 4.8 677de42bd2 fix(simulation): make voxel relief sub-district + fix integration-test fallout (T-1081)
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.

jpmschweitzerandClaude Opus 4.8 1eb098129b fix(simulation): pin SeedDomain::VoxelRelief discriminant + record T-1081 review notes
T-1081 review (Hoshe + Tyre): the seed_domain_discriminants_are_pinned test (the
D-224 guard that fails CI if a variant is renumbered — which would silently re-roll
every world's relief field) did not pin the new VoxelRelief = 11. Add the assertion.

Also fold Tyre's two Q-123 calibration notes into item 4: (i) sanity-check the
slope_q*3 + elev_q envelope on a synthetic high-slope body (both terms cap at 100);
(ii) the relief transect is a single diagonal slice (fine for isotropic fBm, revisit
if an anisotropic ridge field is added).

jpmschweitzerandClaude Opus 4.8 ab6e1413d9 feat(simulation): voxel-tier mid-scale relief — navigable hills (T-1081)
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.
