Atlas-derivation workshop output (Jeroen + Tyre / Nigel / Burnelli / Gestalt). The foundational world-derivation model: - D-227 deterministic-rebuild world model: world = pure function of seed+atlas, derived on demand + cached, only tile mutators persisted, fully volumetric (voxel / subvoxel), vertical extent physical not floor-count, variable-height floors (cave/basement/built all count). - D-228 composite tile schema: orthogonal axes (TerrainMaterial / FloorMaterial / Vegetation / Water / elevation), derived shape + tactical form, region-level morphology zones, cohesion matrix, dynamic clock-bound region seasonal state (water-height / snow / weather / crop-cycle from one cheap per-region calc). - Q-100..Q-105: biome authority, refinement contract (+ body-class river density + ocean mask), cohesion-matrix algorithm, mutator op schema, floor-to-voxel-z mapping, region seasonal/clock state. - Workshop brief: docs/workshops/atlas-derivation-model.md. Epic #974 + ocean-mask story #975 track implementation (Phase 4 milestone). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Decisions
Confirmed decisions, open questions, and rejected alternatives for The Settled Reach.
Decisions are split by domain. Each agent's briefing indicates which files to read. When in doubt about where a decision belongs: if it constrains how we build, it's architecture. If it defines what we build, it's scope. If it defines what the player experiences, it's content or perception. If it defines how the team works, it's process.
Cross-domain decisions live in one file with cross-reference notes in related files. Split threshold: when any file exceeds ~350 lines, review whether it should split.

Querying Decisions
The SQLite database contains a decisions table synced from these files. Common queries:
# All active architecture decisions
tooling/db/sqlite-query "SELECT id, title FROM decisions WHERE domain='architecture' AND status='active'"
# Decisions without implementing tickets
make decisions-orphan
# Decision coverage by domain
make decisions-coverage
Adding a Decision
- Edit the appropriate domain file
- Follow the existing format (
### D-NNN: Titleheading) - Commit — the pre-commit hook runs
decisions-syncautomatically - Update relevant agent briefings if needed
