# smartupdate improvement plan

Status: implemented.

## Goal

Make update checks predictable, cache-safe, and testable without changing the core public API shape.

## Implementation

- Fix CLI cache behavior so cached update information still reports an available update and time-based cache entries expire.
- Cache both `update-available` and `up-to-date` results so normal repeated CLI runs do not keep hitting the registry.
- Store cache context with each entry and only reuse cache entries for the same package, current version, and registry.
- Preserve more useful error types for invalid package names, invalid versions, package lookup failures, and registry failures.
- Await and catch changelog opening so browser failures do not become unhandled promise rejections.
- Replace live npm tests with deterministic registry stubs and ephemeral cache storage.
- Remove unused dependency surface.

## Verification

- Run `pnpm test`.
- Run `pnpm run build`.
