Stale architecture documentation creates two costs: maintenance work and the risk that someone treats it as current. The correct response is not always to update it.

> **Direct answer:** Update a stale artifact when it serves an active audience and its scope is maintainable. Archive it when it explains a meaningful historical decision or past system state. Delete it when it has no continuing value, duplicates a better source, or would mislead readers even with a label. Simplify it when the detail level is the reason maintenance keeps failing.

## Update: active and valuable

Update the artifact when teams still use it for onboarding, architecture review, incidents, compliance, or cross-team coordination. Confirm an owner and update trigger before investing effort; otherwise it will drift again.

Do not perform a one-time cleanup without changing the process that caused the decay.

## Archive: historically meaningful

Archive signed-off designs, migration plans, and diagrams linked to ADRs when they explain why the system evolved. Add a visible banner with the covered period, superseding artifact, and status.

Historical accuracy does not require current accuracy. The artifact should represent what the team believed at that time.

## Delete: noise without value

Delete drafts, duplicates, accidental exports, and orphaned diagrams that have no meaningful history. A directory full of nearly identical files makes the authoritative artifact harder to find.

Deletion should follow your organization's retention and compliance rules. The goal is clarity, not indiscriminate cleanup.

## Simplify: too detailed to survive

A diagram that repeatedly drifts may be documenting the wrong level. Remove volatile details and retain stable boundaries, responsibilities, and major flows. Let code, schemas, or generated tools provide lower-level facts.

Simplification is often the highest-value action because it reduces future maintenance.

## Use a cleanup checklist

For each artifact, ask:

- Who uses it?
- What decision or task does it support?
- Is another source more authoritative?
- Can the team realistically maintain this level of detail?
- Does it explain a historical choice?
- What harm could an incorrect reader experience?

The answers usually make the correct path obvious.

## Where Arialine fits

Arialine preserves diagram versions as an additive history while keeping one current anchor artifact. Boards can be archived when they no longer represent a maintained system. This prevents old versions from competing with the latest one while retaining decision provenance.

## FAQ

### Is deleting documentation dangerous?

Keeping misleading documentation is also dangerous. Follow policy, preserve meaningful history, and remove noise deliberately.

### Should archived diagrams remain searchable?

Yes, but their historical status and superseding artifact should be unmistakable.

### How do we simplify a complex map?

Start by removing implementation detail that changes frequently and split distinct audience questions into separate focused diagrams.
