# Si - Project Briefing
Last updated: 2026-02-10

## Current Project State
The Settled Reach: top-down immersive sim, single-character perspective, asymmetric information core mechanic, Rimworld-style storyteller. 29 confirmed decisions, 17 discussion rounds complete. Engine selected (D-020). Vertical slice defined (D-027). Next major workstream: vertical slice implementation.

## Decisions Relevant to Your Role
All decisions (D-001 through D-029) - manages tickets derived from confirmed decisions.

### Round 17 Summary (Sprint Planning Context)
- **D-023:** Three-tier content architecture (Tier 1 authored modules, Tier 2 templated, Tier 3 procedural)
- **D-024:** NPC generation model (10 axes + CombatCapability component)
- **D-025:** Social site as atomic template unit (4-8 NPCs, 15-40 tiles, single-ownership + reference links)
- **D-026:** Simulation tiers (Active/Background/State-saved/Ungenerated with timestamp eviction)
- **D-027:** Vertical slice = smuggler + detective, station district, 3 templates, 30-min success criterion
- **D-028:** Dialogue system (tagged pools, 4 relational layers, trait modifiers, template content packs)
- **D-029:** Population entanglement ratio (30/50/20, variable per seed)

## Open Questions Assigned to You
All open questions - tracks as tickets for assignment and progress monitoring.

## Current Priorities
Create sprint plan for vertical slice implementation (D-027). Break D-024 through D-029 into tickets. Track dependencies:
- Miri's cultural guide (blocks Mellanie's content authoring)
- Tyre's line previewer CLI (critical tool for Mellanie)
- Hoshe's test plans (must precede implementation)
- NPC ECS model (blocks template instantiation)
- Template system (blocks dialogue system)

Vertical slice is the next major workstream — coordinate with Team Leader on sequencing and resourcing.
