# Session State

<!-- STATUS -->
Epic: Pre-Production
Feature: System GDD Authoring
Task: Combat Logic GDD complete (GDD #2)
<!-- /STATUS -->

## Completed This Session

- [x] `/brainstorm` → Game concept: 夜裔 (Nightborn) → `design/gdd/game-concept.md`
- [x] `/setup-engine` → Unity 2022.3.62f3c1, C#, URP configured
- [x] `/art-bible` → Sections 1–4 (Visual Identity core) → `design/art/art-bible.md`
- [x] `/map-systems` → 17 systems indexed → `design/gdd/systems-index.md`
- [x] `/create-architecture` → Master architecture → `docs/architecture/architecture.md`

## Key Decisions

- Architecture: L0 Pure C# (no Unity) / L1 Unity Adapter / L2 Unity Presentation
- L0→L1 communication: C# event only (L0 never calls up)
- asmdef: Core (no Unity refs) → Adapters (Core + Unity) → Presentation (Core + Adapters + Unity)
- Visual: Minimalist geometric — Triangle (human), Rectangle (wolf), Circle (mist)
- Review mode: Lean (default)
- 3 forms: Human (precision), Wolf (burst), Mist (control)
- Form switching: Resource-driven (Blood Energy), rhythmic (commitment animation)
- External developer model: GDD = deliverable spec; /code-review = acceptance gate

## Pending ADRs

- BLOCKING: ADR-001 (Three-Layer Architecture), ADR-002 (Event Bus), ADR-003 (Pure C# Geometry)
- HIGH: ADR-004 (Form Switch SM), ADR-005 (Enemy AI Model)
- MEDIUM: ADR-006 (Wave Data Format), ADR-007 (Serialization)
- LOW: ADR-008 (Skill Tree), ADR-009 (Score Formula)

## Current State

- **Phase**: Pre-Production — Architecture complete, GDDs pending
- **Next**: Design individual system GDDs in dependency order
- **First GDD**: Blood Energy Economy
