# Continuity Boundaries
## What must be durable—and what must remain ephemeral

## Core stance
Not everything should persist.
Continuity is as much about **letting go safely** as it is about preserving.

## Durable vs ephemeral
Durable:
- Intent
- Consent
- Authority boundaries
- Causal understanding

Ephemeral:
- Drafts
- Experiments
- Temporary workarounds
- Exploratory data

## Boundary failures
- Everything is kept “just in case”
- Nothing is trusted enough to delete
- Memory becomes noise

## Exercises
- Classify one system’s artifacts as durable or ephemeral
- Identify one thing being over-preserved
- Define a safe forgetting rule

## Suggested next step
Publish a durability boundary for one domain.
