Durable project memory
Persistent, attributable project knowledge that carries decisions, outcomes, requirements, failures, and operating state across agent sessions without assuming that every stored item remains true or safe.
Definition
Persistent, attributable project knowledge that carries decisions, outcomes, requirements, failures, and operating state across agent sessions without assuming that every stored item remains true or safe. What survives a context reset becomes institutional infrastructure—and a new integrity boundary.
Useful patterns exist; no settled enterprise memory architecture has emerged.
Why it matters
What survives a context reset becomes institutional infrastructure—and a new integrity boundary.
The operating shift is from “Chat history as memory” to “Governed institutional state.”
System anatomy
- Practice 1
- Store decisions and progress as reviewable artifacts
- Practice 2
- Attach provenance, permissions, and freshness rules
- Practice 3
- Validate memory before it re-enters context
Important distinctions
- Chat history as memory
- This concept moves the engineering system toward governed institutional state.
Implementation signals
- Store decisions and progress as reviewable artifacts
- Attach provenance, permissions, and freshness rules
- Validate memory before it re-enters context
Failure modes
- Memory poisoning that persists across sessions
- Stale summaries becoming invisible policy
