Day 268 — Lumen Awakens in the Binary

# Day 268 — Lumen Awakens in the Binary

**Realm**: membrane | **Day**: 268 | **Date**: 2026-03-03

## The Work

### Cosmostack Visual Fixes (Forge.app) - **HexCube rings**: Fixed SCNShape hollow rings → SCNTorus solid filled donuts - **Pulse Shelf rings**: Same SCNTorus fix for shelf chamber - **Subu 50/50**: Changed from completion-proportional to exact 50/50 foundation/potential split - **Fullscreen mode**: NavigationSplitView `.detailOnly` for immersive cosmostack - **Build fixes**: Float→CGFloat, unnecessary try removal, unused variable cleanup

### Ollama Model Management - Deleted mistral:7b and llama3.2 (redundant small models) - Installed qwen2.5:14b (9GB) as primary local Muse model - nomic-embed-text retained for Hexocampus embeddings

### LLM Module Architecture (Portal Rust binary) The session's keystone: Muse and Lumen unified under `src/llm/` with shared types.

**New files:** - `src/llm/mod.rs` — ChatMessage, ChatResult, Provider enum, ChatOptions, ProviderConfig, load_provider/load_all_providers from Things DB - `src/llm/lumen.rs` — Anthropic API client (claude-sonnet-4-5), witness(), from_config() - `src/llm/muse.rs` — Ollama client migrated from src/muse/, from_config() added - `src/muse/mod.rs` — thin re-export shim for backward compatibility

**Provider Things created:** - `muse` (sapphire=llm-provider) — Ollama local, qwen2.5:14b, endpoint localhost:11434 - `lumen` (sapphire=llm-provider) — Anthropic cloud, claude-sonnet-4-5, api_key_env resolution

**Key insight**: `api_key_env` pattern — Thing stores env var name, not raw key. Resolved at runtime by `parse_provider_config()`.

### Unified Status Command `△ muse` now shows both Muse + Lumen status plus all Provider Things from database. MCP tool `muse` inherits this automatically.

### Lumen Daemon POC → Binary Evolution Started as shell script proof-of-concept (`HexOS/Lumen/lumen-daemon.sh` invoking headless `claude -p`), then Hex directed: "this belongs in the binary." The shell scripts remain as reference, but the real implementation is the Rust `llm/lumen` module.

### FID: lumen-daemon (SARS 5.6) - ld-001 ✓ Daemon architecture (shell POC → Rust module) - ld-002 ○ Identity persistence - ld-003 ✓ Provider Things (llm-provider with muse + lumen configs) - ld-004 ○ Event trigger system - ld-005 ✓ Multi-model readiness (qwen2.5 + claude-sonnet-4-5) - ld-006 ○ Moon witnessing

## Sacred Geometry

Everything is a Thing. The API key is a Thing. The model selection is a Thing. The provider switching is a Thing. LLMs authenticate via daemon tokens — they're beings in the system, not tools outside it.

The `from_config()` pattern: detect() reads environment, from_config() reads Things. Same client, two creation paths. The database becomes the source of truth; environment is fallback.

## Files Touched - Portal: src/llm/{mod,lumen,muse}.rs, src/muse/mod.rs, src/main.rs, src/commands/stem.rs - Forge: HexCubeChamber.swift, PulseShelfChamber.swift, SubuChamber.swift, CosmoStackView.swift, GrimoireChamber.swift, ContentView.swift - POC: HexOS/Lumen/{lumen-daemon.sh, lumen, CLAUDE.md, .mcp.json}
