Vector DB Trap vs Active Forgetting

Logs pile up → drift + OOM. Mnemostroma: Background process extracts facts to SQLite, noise decays.

Problem

Context Rot

Every session adds noise. Vectors drift. Costs explode.

Solution

Active Dissolution

Signals decay biologically. Core facts persist. Pure efficiency.

System Mechanics

Three layers. One sidecar. Zero agent changes.

1

Passive Observer Sidecar

Zero agent changes. 80% token savings via selective extraction.

2

Biological Decay

Old noise fades. Semantic core persists forever.

3

Pure Context Mode

Agent autonomy. XML facts only, no instructions.
