What It Does
When the tunnel moves, things normally die.
The prosthetic keeps them alive.
- Search: Find what I thought about X, even if I forgot I thought it
- Semantic: "Things like this" not just "exact words"
- Temporal: What was I thinking in August 2024?
- Cross-session: Connect insights across hyperfocus sessions

Is It Working?
Yes.
When I shift focus now, previous sessions don't fully die. They're queryable. The context persists outside my head.
The tunnel still moves. But it leaves a trail.
