D-246 (architecture): intra-class micro-habitat mosaic — a voxel_mosaic()
sub-chunk noise band modulates the D-228 axes into spatially-coherent,
relief-conditioned micro-habitats; palette keyed on surface-class ×
climate-biome × biosphere-register; five new D-228 axis values front-loaded
for determinism; within-patch believability metric in scope. Governs T-1084.
D-247 (content): habitable Reach worlds were alive before humans — the
settlement timeline forbids terraforming from dead rock. An authored per-world
chirality bit gates whether native life is edible (Compatible) or
inedible-but-inert (Mirror); "safe" and "edible" are decoupled; colonization
is ecological war that grows an Earth-crop footprint outward from settlements.
Grounds D-246's native-vs-introduced register.
D-228 amended: +Vegetation{Meadow,Deadfall,Lichen}, +TerrainMaterial{Hardpan,Scree}.

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.

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).

The voxel tier read flat (the D-245 "0–3 m, no hills to navigate by" bug):
family generators set elevation from elev_q at a compressed scale plus only ±4 m
micro-scatter, and detail-scatter's mid-scale relief (D-243 §2) only ever reached
the district tier (elev_q), never per-voxel elevation_m.
- detail_scatter.rs: extract the enveloped-fBm core; add `voxel_relief` at the
0.25–2 km octave band (vs the district 4–40 km band).
- voxel.rs: add the mid-scale relief post-dispatch in derive_voxel_column, body-global
SeedDomain::VoxelRelief seed (position-keyed), f64 truncated to integer metres (D-010).
Envelope = slope_q*3 + elev_q — the coarse heightmap gives slope_q ≈ 0 even on high
ground (Arbour max 13), so elevation must drive ruggedness. Flat families only
(Alluvial/Lava/BraidedDelta/Dune/Meander); the dramatic families already carry strong
internal relief and WaterBody stays at sea level.
- seed.rs: SeedDomain::VoxelRelief (D-224 domain separation).
- believability.rs: new `contrast.voxel_relief_m` metric — mean within-district elevation
range over a 2 km transect (a single 64 m sample chunk is narrower than the relief
band) + a "voxel relief" criterion.
Arbour @ yolo: voxel relief 5 m → 59 m, 6/8 → 7/8 criteria (remaining fail = the
Q-123 vegetation-denominator item). Edict 59 m. Golden regenerated; 1586 lib tests +
believability harness (determinism) pass; clippy -D warnings clean.
D-239 amended (T-1081); Q-123 item 4 updated. Deferred to Q-123/follow-up: the
provisional span + threshold, and a per-body hypsometric absolute-elevation model.

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

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

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

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

settled-reach is always a pql repo, so make the rule repo-canonical (CLAUDE.md +
ticket-cli.md): routine ticket/decision CLI is covered by the rules, but the
load-bearing model lives only in the pql skill — changelog is write-through (never
git-restore it), `export` doesn't replicate ticket_idmap, post-checkout rebuilds
pql.db from the changelog, so cross-branch planning moves must re-create via
`pql ticket`, not changelog surgery. Back up pql.db before risky ops.
The clide-side equivalent (read the clide skill when running inside clide) is an
editor choice, not a repo property — it belongs in a clide-owned SessionStart hook,
not here.

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

Implement the D-230 on-demand derive phase (data-production half). New
atlas/shell.rs derives a sparse building shell for one 64 m chunk from the
plan-phase BuildingPropertyTags: rectangle-containment (footprint ∩ chunk) ×
z-range (per-floor voxel bands from FloorExtent), in a quarter-ground z frame
(D-110). Walls on the footprint perimeter, FloorSlab on interior floor bases,
Roof above the top floor; interior air is Void and never stored.
- gen_queue.rs: GenWorkItem::FillChunk carries pre-resolved block_tags +
block_pos + sub_chunk (run_work_item stays cache-free, mirroring
GenerateSkeleton); GenCompletion::ChunkFilled carries Box<FilledChunk>; the
arm calls shell::fill_chunk; pure build_fill_chunk_item(&QuarterWorldState,..)
added.
- plugin.rs: ChunkFilled handler accepts the shell (trace-only — the Phase-5
rendering consumer and the on-demand streaming dispatch trigger are deferred;
do not build on legacy chunk_streaming.rs before Phase 5, gated by T-962).
Tests: determinism, sparsity-vs-dense-volume, wall/floor/roof correctness,
basement z-origin, sub-chunk clipping, full submit→drain→ChunkFilled round-trip.

Addresses PR #170 review (Hoshe H1/H2).
H1: the Some(basin_dirs) path through derive_all_districts was untested (tests
only used None). Added derive_all_districts_threads_supplied_basin_directions
(synthetic per-district directions propagate to DistrictProfile.basin_direction;
unmapped districts fall back to North), and added basin_direction to the cascade
determinism loop so the full run_layer1->district chain is guarded.
H2: clarified the derive_district on-demand comment — the North default is an
accepted limitation (a fallback, not a computed value); the batch path threads
the true D8 direction.

T-1044: run_layer1 now returns TerrainAnalysis (carried transiently on

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).

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

Separated the asset pipeline from the cascade work. T-1049/T-1050 assume a sprite-centric
catalog; direction is 3D objects (Trellis .glb) in-world with textures as the only
flattened content. Held for re-scope. Cascade track (T-1044/T-1047) continues.

Two parallel tracks with refinement appends: T-1044+T-1047 compose on the run_layer1

Hoshe H1: the morphology_zone AlluvialPlain fallback fired silently. Now logs
tracing::debug! when the district grid is empty (expected: params-missing body /
early cascade) and tracing::warn! when a populated grid misses the key (indicates a
pixel->district convention bug) — no more silently-wrong topology.
Hoshe H2: the arrangement_pattern parity tripwire only covered transit_hub with
Commission + Corporate. Added Pioneer/Industrial/Military/Academic rows so an
accidental archetype-conditionalization of the cross-archetype override is caught.
Tyre (non-blocking): clarified the build_skeleton_work_item doc — the
arrangement_pattern re-derivation call lives in generate_quarter_skeleton (the
consumer), not in this function.

Refines 34ffcda86. The export --stage approach preserved the mutation but did more
than the bug needs: it eagerly stages changelog rows mid-checkout (surprising in
git status), and those staged rows can leak onto the wrong branch when a later
switch rebuilds by replaying the working-tree changelog.
Minimal fix: on a branch *creation* / no-op checkout (prev-HEAD == new-HEAD) the
working tree is unchanged, so pql.db already holds the committed state plus any
uncommitted mutation — just skip the whole block (do nothing). The mutation stays
in pql.db untouched and the next commit's pre-commit hook flushes it normally. Only
a real branch *switch* (prev != new) rebuilds. No git-index side effects, no leak.
Verified: same-HEAD invocation preserves an uncommitted status mutation and stages
nothing. (Credit: pql-clide's review of the upstream feature request.)

The post-checkout hook ran 'pql plan rebuild' (drop + replay changelog) on every
branch checkout, including 'git checkout -b'. That silently dropped any pql.db
ticket mutation not yet in the committed changelog — e.g. an in_progress status set
right before cutting a feature branch (hit this session: T-1039/T-1043 reverted to
backlog at branch creation).
Git has no pre-checkout/pre-worktree hook, so capture the changelog at post-checkout
instead: when prev-HEAD == new-HEAD (a branch *creation* — content unchanged, pql.db
already correct), run 'pql plan export --stage' (the same flush the pre-commit hook
does) instead of the destructive rebuild. Real branch *switches* (prev != new) still
rebuild to match the branch's changelog.
Verified: simulating a same-HEAD checkout with an uncommitted in_progress mutation now
preserves it (previously reverted).

Completes the GenerateSkeleton dispatch T-1022 wired (which only carried
founding_orientation). build_skeleton_work_item now also threads:
T-1039:
- political_archetype — real value from CityPlacement, replacing the Commission stub.
- morphology_zone — looked up from the covering DistrictProfile via new
scale::heightmap_pixel_to_district (exported HEIGHTMAP_CELLS_PER_DISTRICT;
cascade.rs drops its local CELLS_PER_REGION literal for the shared const).
- arrangement_pattern — RE-DERIVED at L4 (option b) via the single pure fn
attractor_matching::arrangement_pattern(&archetype, &economic_role); both
inputs already at L4. No CityGenerationContext field, no stored derived state
(DB-as-cache). Parity test asserts L4 re-derivation == L3-stored value.
T-1043:
- road_entry_directions — derived from T-1038's BodyWorldState.road_graph:
octant = bearing of each incident road edge, deduped per octant, ordered by
MaintenanceAuthority rank (the AdminFacing prestige-edge consumer). Feeds
derive_access_points -> AccessKind::QuarterEdge; BlockJunction fallback now
fires only for genuinely isolated settlements.
Acceptance covered: Corporate+Fjord -> Ribbon topology (not mesh+Commission);
settlement with a road -> QuarterEdge on the correct octant. 11 new tests.

Addresses PR #167 review (Hoshe H1/H2/H3, Tyre T2).
H1 — the VoxelCache 'same (seed, body_id, tile_pos) -> same column' invariant
is no longer unconditional after the T-1042 blend (the key omits blend_weight/
secondary). Replaced with an explicit precondition on the struct + get_or_derive:
the caller must pass the ChunkContext of the chunk that contains the tile.
H2/T2 — sec_phase claimed to be 'position-independent' but mixed in
primary_meander_phase/2 (the primary's per-position seed), making the secondary
phase proxy asymmetric and primary-contaminated. Dropped that term; sec_phase is
now the secondary's own morphology scalars (slope_q + moisture_q), with a comment
honestly naming it a bounded cosmetic approximation and where to thread the real
secondary seed if needed.
H3 — added cache_boundary_tile_blend_is_stable: derives a boundary ChunkContext
(blend_weight=128, secondary=Some), calls get_or_derive twice, asserts a cache
hit + identical blended elevation + that the Cow::Owned blend path actually ran.

Addresses PR #167 review (Tyre T1, T3).
T1 — the region climate tier was built but no live path consulted it: both
derive_district_profile (cascade) and derive_district (on-demand) passed
region_baseline_c: None, so the D-243 §4 edge-fuzz blend was dead in production
and district temperature was still derived from scratch. Now both paths compute
region_baseline_at_district(...) and pass it through build_district_profile so
the two-phase modulation (D-243 §3) actually runs. The cascade path
(derive_all_districts) builds a BTreeMap<RegionPos, RegionProfile> covering all
district positions + their +/-1 neighbours once per body and looks up from it;
the on-demand path derives the four surrounding region baselines on the fly.
No production path passes None except genuinely airless bodies (no planet_class).
T3 — renamed BodyParams.district_latitude_deg -> latitude_deg (it is the region
centre latitude in the region fns, a call-site trap under the old name);
dual-scale doc; propagated to body_params_reader.rs and all literal sites.
Golden fixtures are unaffected (they construct districts directly via make_region,
bypassing build_district_profile) — derivation_harness 37/37 green, no re-pin.

test_proof_corner_reveal drove moves back-to-back. The Gauntlet player is
Walk stance (ticks_per_move=2, server stance.rs), so a move arriving within
the cooldown window is silently throttled (movement.rs::apply_move ->
PlayerMoveCooldown::try_move). _send_and_receive returned the instant a move
landed, so the next send raced the cooldown and an occasional move was
dropped — leaving the player one tile short, which (via the test's cumulative
expectations) cascaded into the corner-reveal perception assert. A different
move dropped each run = flaky; exposed by the heavier post-cascade tick timing.
Test-side fix only — game behaviour is correct and the Gauntlet world is
immutable: after a move lands, wait for the server clock to advance
COOLDOWN_TICKS past the landing tick before the next send. Full client suite
2538/2538 green; the proof suite drops from ~28s (timeouts) to ~4s.

Replaces the single-DistrictProfile walking-skeleton restriction so
continuous terrain parameters no longer step at the 2 km district pitch
(D-239 §4/§7/§8). ChunkContext gains secondary: Option<DistrictProfile> +
blend_weight: u8; derive_chunk_context detects a chunk within one chunk of
a district border, looks up the adjacent profile, and integer-blends
meander/channel params on the context. derive_voxel_column integer-blends
elev_q/moisture_q before material selection, reusing the same warp offset so
the seam cannot align with the chunk edge (Cow fast-path keeps interior
chunks bit-identical — golden seed unchanged).
Morphology FAMILY selection is never blended — stays sharp per D-239 §7
(family dispatch reads the primary district only). Climate feathering is the
separate T-1078 path. Adds cross_district_elevation_blend_reduces_seam_step
and cross_district_morphology_family_seams_stay_sharp to the derivation

edge-fuzz warp-perturbed bilinear blend of surrounding region baselines so
the ~205 km grid is invisible in the output.
Splits district temperature (D-243 §3): derive_district_temperature_c now
modulates the region baseline with elevation lapse only, replacing the
from-scratch per-district derivation. build_district_profile takes an
Option<f32> region baseline; None preserves the legacy single-phase path
(existing call sites unchanged). derive_cover (voxel.rs) consumes the
post-refactor value with no signature change.
Region clock (season/weather) scaffolded; transient tick callbacks deferred
to Q-105 per the two-phase convention. 14 region_profile + 5 district
modulation tests added.

/whats-next batch activation for the D-243 region-tier finish.
Refinement briefs (Si pass) appended to T-1042 and T-1078 reconciling
their 2026-06-12 scope against the post-T-1077 tree. T-1046 (Region→
Chunk→Voxel wiring) flipped to done — already committed in cfd5e18d0.

Client half — the cascade's district tier is now visible in the Atlas map.
- protocol.gd: decode the district_grid field from AtlasLayerResponse.
- atlas_viewer.gd: a gen_district ('MRPH') toggle in OVERLAY_DEFS + the
district-grid generation state (set/get) + wire it from the Ready response.
- atlas_marker_overlay.gd: _draw_gen_district() paints the coarse cols×rows grid,
each cell coloured by its MorphologyZone discriminant (D-239 §6, 17-zone
palette), semi-transparent under the Layer-1 line overlays. Planetary map view
(not the 2km on-demand districts — those are Phase 5 in-world).
gdUnit4 test: overlay registered + district grid round-trips through the viewer
and the protocol decode. Visual tuning of the palette can follow once eyeballed
in the running Atlas.
