# Continuity Architecture
## Designing systems with time as a first-class constraint

## Core stance
Most systems are designed for performance and scale.
Few are designed for **survivability over time**.

Continuity architecture treats time as a design input, not a byproduct.

## Continuity primitives
Continuity-aware systems include:
- Decision provenance
- Reversibility paths
- Explicit ownership
- Explainable failure modes
- Drift detection signals

## Architectural failure modes
- One-way migrations
- Hidden state accumulation
- Configuration without rationale
- Automation without rollback

## Exercises
- Identify one irreversible architectural choice
- Add a provenance note to a system boundary
- Define one rollback or exit path

## Suggested next step
Introduce a continuity review gate for high-impact designs.
