 - **Rationale:** The heightmap pipeline was designed with Phase 3 in mind — 2,394 base maps exist. The critical path is content (filling empty markers.json arrays), not technology (the atlas panel follows the established implant component pattern). Sequential settlement growth simulation produces more realistic city networks than scatter placement — each city's location is informed by previous placements, terrain, and economic logic. Using the Gemma 2 voice pipeline for naming tests the in-game LLM quality while generating content. Population-scaled depth without manual tier classification keeps the pipeline simple and the authoring burden manageable.

 - **Rationale:** Administered pricing is the correct model because brands violate all three tâtonnement assumptions: heterogeneity (Calloway ≠ VGV ≠ generic spirits), supply inelasticity (terroir production cannot respond to price signals per D-177), and Veblen demand effects (prestige goods can have upward-sloping demand). The one-way interface (commodity prices → brand input costs; brand output prices do NOT feed back into tâtonnement) is architecturally clean and matches the D-178 layer model. The identity/exotic split in cultural premium is the minimal structural addition needed to produce all three observed pricing curves (Scarcity-Distance, Dual-Peak, Aspirational Gradient). Population asymmetry (~80B total Reach population, systems ranging from 10B to <50k) makes the halo/volume tier pattern structurally necessary — brands from tiny worlds are astronomically exclusive and need volume derivatives to be economically relevant.

   - **Earth rule of thumb:** multiply Earth-scale phenomenon volumes by 12–15× for comparable cultural penetration. A 100M-seller on Earth ≈ 1.2–1.5B in the Reach.
   - **40M benchmark:** 40M units/streams Reach-wide = 0.04% penetration — a cult hit or successful regional release, not a cultural touchstone. 40M within a single large system (10B population) = 0.4% — respectable but not legendary.
   - **Authoring rule:** wiki volume figures for media brands and any good with `brand_category = cultural` must include a `reference_population` annotation alongside the count. "40M" is incomplete; "40M (west_reach corridor, ~10B addressable)" is correct. This applies to corporation production ceilings, media distribution figures, and market penetration estimates in wiki pages and TOML files.
