# What should an agent revisit when the world changes?

Living Context: Reference implementation. Published 24 Sep 2026. Question: Does the state hold up?
Scope: In-memory, model-free reference
Page: https://jasonlovell.ai/work/living-context
Code: https://github.com/jlov7/living-context

Revision-aware context snapshots, text retrieval and advisory refresh plans.

## Demonstrated

Tracking revisions explicitly is enough to propose which context to refresh, with no model involved. The learned-context extension came out negative or inconclusive.

## In practice

Stored context goes stale. Track what changed and plan what to re-read, instead of keeping everything.

## What I built

An in-memory, model-free reference for tracking revisions and planning which context to refresh.

## Where the evidence stops

An in-memory reference, not a deployed model-serving or replicated distributed-memory system.
