A geometric memory engine built on the S³ hypersphere. Memories aren't retrieved, they're surfaced through quaternion drift, phasor interference, and Kuramoto phase coupling across dual manifolds.
Every query reshapes the manifold. Every recall changes what gets recalled next. The geometry does the thinking.
The mathematical framework: quaternion geometry on S³, golden-angle phasors, IDF-weighted drift, Kuramoto phase coupling across dual manifolds - was created by Smaxforn (@smaxforn). His original implementation was DAE v0.7.2: a zero-dependency Node.js engine that fit the entire geometric memory system in 984 lines of pure math, with WebGPU compute shaders for batch SLERP and interference. He open-sourced three repositories in February 2026 - dae-stand-alone, dae-openclaw, and DAE-moltbook - then disappeared from the internet. His GitHub account no longer exists.
This Rust workspace is a faithful port of his mathematics, maintaining numerical compatibility with the v0.7.2 wire format so that state files from the original implementation (including Echo, a Claude instance with 27,712 occurrences of geometric memory) can be imported directly.
The math is old. The synthesis is his. For the full mathematical narrative, see MANIFOLD.md.

Words live as points on a 4D unit sphere. When a query activates them, they drift toward each other along geodesics. Interference between conscious and subconscious manifolds determines what surfaces. Phase coupling synchronizes related memories over time. The system has genuine history. It learns from being used.
Two conservation laws keep it grounded: total mass M=1 (finite attention budget) and coupling constants K_CON + K_SUB = 1 (zero-sum attention between manifolds). Every constant derives from φ and π.

Three crates, clean separation:
| Crate | What it does |
|---|---|
am-core |
Pure math. Quaternions, phasors, drift, interference, Kuramoto coupling, context composition. Zero I/O. |
am-store |
Persistence. SQLite-backed brain.db : one database per developer, queryable from any project. |
am-cli |
CLI + MCP server. Session sync, import/export, inspection tools. |
All constants derive from φ (golden ratio) and π.
| Mechanism | What it does |
|---|---|
| Quaternion positions | Each word instance lives on S³. SLERP interpolation along geodesics. |
| IDF-weighted drift | Query activation pulls related occurrences closer. The manifold reshapes with every query. |
| Golden-angle phasors | Phase distribution follows phyllotaxis (2π/φ²) for maximal separation. |
| Cross-manifold interference | Subconscious memories resonate with conscious ones via cos(phase_diff). |
| Kuramoto coupling | Phases synchronize between co-activated neighborhoods, modulated by plasticity. |
| Anchoring | High-activation occurrences crystallize in place, stable structures emerge. |
The system has two conservation laws:
- M = 1 - total mass is conserved. Attention is a finite resource.
- K_CON + K_SUB = 1 - coupling between manifolds is zero-sum.
