+Refinement (/whats-next 2026-07-08): AUTHORED-DEPTH v1 (user decision — "deliver what we want to deliver in the first run"; pull Miri + Araminta into the ticket for the content catalog). RESOLVED:
+1. Derivation is 3-STEP, era-free (D-235 amendment / D-232 reframe): template visual_bundle filter -> zone_type bias -> density setback + interstitial type. Drop the stale "era restrict" step and "era-adjusted" color — era reads as wear via D-217 condition, never a material gate.
+2. Phase timing (per the T-994 precedent, same rationale): BuildingExteriorTag is resolved at GenerateSkeleton dispatch/plan time — where context, catalog, and flavor_ref resolution are available — and stored FROZEN on BuildingPropertyTag; FillChunk only reads it (T-987 purity). Swerve(tag) refs resolve against the full catalog at the same point.
+3. trait_catalog_reader must be extended to parse visual_bundle (+ the new fields below) — currently explicitly unparsed ("D-235 territory").
+4. Vocabulary becomes append-only integer-discriminant Rust enums (WallMaterial/RoofForm/FacadeRhythm/StreetSurface), matching the SeedDomain/DistrictType convention; unknown registry strings parse to the axis generic with a tracing warning (patch tolerance). Registry TOML remains the authoring source (V-TT-03/04 validated).
+5. Zone bias is a REAL authored table: per-template zone_type -> token weight overrides (integer bps), authored by Miri (cultural meaning) + Araminta (visual coherence) into the catalog TOML alongside visual_bundle; importer-validated (new V-TT check: referenced tokens exist in the template''s own visual_bundle axis). Uniform fallback where unauthored.
+6. color_range is a NUMERIC model now: per-color_register authored integer ranges (e.g. HSV/OKLCH components as integer bps bands, D-010 — no floats), one table keyed by the 28 color_register values, Araminta-authored; per-building seed pick within the template''s register band, stored as integers on BuildingExteriorTag.
+7. StreetSurface is IN SCOPE here: derived per street/interstitial run with the same template filter (D-235 "same filter as buildings"), stored alongside the interstitial type.
+8. setback_tier: fixed 5-tier vocabulary (zero_lot | tight | standard | generous | campus) derived from BlockSkeleton.density_pct bands (the shipped axis; D-220 DensityClass has no code representation) — thresholds documented as calibration placeholders.

Answer or ticket each before T-959 kicks off; Q-103 and Q-102 are the most load-bearing.
