Goal

Define and implement a Spatial Memory Schema that maps memories to persistent locations in the 3D Nexus world. Currently, memory orbs are temporary (30s fade). This schema gives memories permanent spatial homes organized by semantic category.

Requirements

1. Memory Region Map

Define named zones in the Nexus world, each corresponding to a semantic category:

Code & Engineering — East quadrant
Conversations & Social — West quadrant
Documents & Knowledge — North quadrant
Projects & Tasks — South quadrant
Archive (cold storage) — Underground/below

2. Schema Structure

{
  "regions": {
    "engineering": {
      "center": [10, 2, 0],
      "radius": 8,
      "color": 0x4af0c0,
      "icon": "code",
      "memories": []
    }
  },
  "memory": {
    "id": "mem_<hash>",
    "content": "...",
    "category": "engineering",
    "position": [x, y, z],
    "source": "session|mem_palace|manual",
    "timestamp": "ISO8601",
    "strength": 0.0-1.0,
    "connections": ["mem_<other_id>"]
  }
}

3. Persistence

Memory positions persist across sessions (stored in ~/.hermes/mnemosyne/spatial_index.json)
On Nexus load, existing memories are restored at their saved positions
New memories are assigned positions within their category region

4. Visual Indicators

Each region has a subtle ground marker (colored ring/particle field)
Persistent memories use a different visual style than temporary orbs (e.g., crystal instead of sphere)
Memory strength affects opacity/glow intensity

Priority

This is the foundation — all other Mnemosyne features depend on having memories in fixed, meaningful locations.

Target Files

app.js — new spatial memory system section
nexus/components/spatial-memory.js — schema and region definitions

## Goal Define and implement a **Spatial Memory Schema** that maps memories to persistent locations in the 3D Nexus world. Currently, memory orbs are temporary (30s fade). This schema gives memories permanent spatial homes organized by semantic category. ## Requirements ### 1. Memory Region Map Define named zones in the Nexus world, each corresponding to a semantic category: - **Code & Engineering** — East quadrant - **Conversations & Social** — West quadrant - **Documents & Knowledge** — North quadrant - **Projects & Tasks** — South quadrant - **Archive (cold storage)** — Underground/below ### 2. Schema Structure ```json { "regions": { "engineering": { "center": [10, 2, 0], "radius": 8, "color": 0x4af0c0, "icon": "code", "memories": [] } }, "memory": { "id": "mem_<hash>", "content": "...", "category": "engineering", "position": [x, y, z], "source": "session|mem_palace|manual", "timestamp": "ISO8601", "strength": 0.0-1.0, "connections": ["mem_<other_id>"] } } ``` ### 3. Persistence - Memory positions persist across sessions (stored in `~/.hermes/mnemosyne/spatial_index.json`) - On Nexus load, existing memories are restored at their saved positions - New memories are assigned positions within their category region ### 4. Visual Indicators - Each region has a subtle ground marker (colored ring/particle field) - Persistent memories use a different visual style than temporary orbs (e.g., crystal instead of sphere) - Memory strength affects opacity/glow intensity ## Priority This is the foundation — all other Mnemosyne features depend on having memories in fixed, meaningful locations. ## Target Files - `app.js` — new spatial memory system section - `nexus/components/spatial-memory.js` — schema and region definitions
