# BRIEFING — 2026-10-02T02:08:00Z

## Mission
Deep specification mining for 30 Dark Fantasy Cổ Võ Hoang Vực Map Styles & SQLite Database in FreeExile.

## 🔒 My Identity
- Archetype: Specification Miner
- Roles: Specification Mining, System Architecture Survey, SQLite & Catalog Design
- Working directory: c:\Projects\FreeExile\.agents\teamwork\spec_miner_survey_3\
- Original parent: 327366ba-dd05-4805-b53b-659a199b1450
- Milestone: 30 Map Styles, Database & Specs

## 🔒 Key Constraints
- Read-only exploration: Do NOT implement or edit source code directly
- Discover and document features by probing authoritative specification
- Comprehensive spec for 30 Dark Fantasy Cổ Võ Hoang Vực map styles
- SQLite Database schema for `data/map_styles.db` (tables: map_styles, map_style_tiles, map_style_props)
- Catalog synchronization specs for Python (`server/world/map_style_catalog.py`) and Client JS (`client/webapp/js/data/map_style_catalog.js`)
- Asset directory conventions (isometric dimensions 64x32 base, 128x64 tileset, texture layouts)
- Follow Handoff Protocol (Observation, Logic Chain, Caveats, Conclusion, Verification Method) in `handoff.md`

## Task Summary
- **What to build**: Specification for 30 dark fantasy map styles, database schema, code catalogs, asset conventions
- **Success criteria**: Exhaustive catalog of 30 distinct styles across 6 themes, complete SQLite schema definition, synchronization mapping, asset specs, edge cases, tables of features
- **Interface contracts**: `PROJECT.md` / `GEMINI.md` / `data/game_design_matrix.db`
- **Code layout**: Python server `server/world/`, Client webapp `client/webapp/js/data/`, Database `data/`, Assets `client/webapp/assets/`

## Loaded Skills
- None explicitly assigned

## Key Decisions Made
- Partitioned 30 styles evenly across 6 canonical grimdark themes (5 styles per theme).
- Preserved 100% backward compatibility for legacy biomes 1-5 (`BLEACHED_BONE_CANYON`, `SAVAGE_MANGROVE_SWAMP`, `CRIMSON_BLOOD_FOREST`, `OUTCAST_MINE_SHAFTS`, `CORRUPTED_FIEND_RUINS`).
- Established normalized SQLite schema with 3 tables: `map_styles` (30 records), `map_style_tiles` (20 tile types), `map_style_props` (placement rules & footprint).
- Standardized asset conventions: base 64x32 px, pattern 128x64 px, walls 128x128 px, normal maps with B mean > 128.
- Outlined decoupling of catalog into types (`map_style_types.py`), catalog (`map_style_catalog.py`), schema (`map_style_schema.py`), and service (`map_style_service.py`) to satisfy code hygiene rules.
