T-988 — BuildingExteriorTag {wall_material, roof_form, facade_rhythm,
setback_tier, color:HsvColor, street_surface}. New trait_exterior.rs:
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.)
T-1097 — BlockSkeleton.interstitial_character (OpenSpace|OperationsSurface),
D-233 bulk-driven: bulk-industry blocks' non-roofed remainder tags as built
economic infrastructure, not generic open space.
cargo check --all-targets clean; 1666 lib tests pass; no golden impact
(harnesses top out at CascadeLayer::RoadGraph, unreachable by Layer 4/5).

T1: heritage corridor_pool excluded from the ordinary phase-1 lottery and
coverage repair (D-232 reserves the heritage sub-pool for the remoteness
dial); reachable via hero pin, necessity swerve, and the T-1003 heritage
pool only. 3 new tests.
T2+H4: coverage repair no longer grows trait_selection past K when all
slots are pinned (phase-2 necessity swerve serves the type instead);
runtime warn when authored pins exceed K; V-TT-05 importer guardrail
bounds pins per body at 5 (max ComplexityTier K). 2 new tests + 2 python
tests.
H1: body-level dispatch aggregation extracted to pure
aggregate_body_dispatch_inputs + tested directly (union mix, MAX
prosperity/K); threading test asserts identical vocabulary/pools across
co-body settlements with per-settlement swerve rates. 2 new tests.
H2: tooling/economy-db/test_traits.py — 14 stdlib unittest cases over
V-TT-03/04/05 failure branches, wired into make test-tooling.
H3: hard-gate JSON parsers now tracing::warn on malformed blobs (silent
gate-widening) matching the sibling map parsers.
H5: catalog read memoized (OnceLock) — SQL+parse once per server run,
bias stays per-body. 1 new test.
T3: TraitDistrict seed-domain doc aligned with the two-level derive chain.
T4: D-225 misattribution dropped from the reader module doc.
systems.db regenerated + stamped (traits.py is a stamped source).
Gates: full cargo test 1638 green (goldens intact), clippy -D warnings,
ruff, make test-tooling (now incl. the traits units).

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