# client-application-testing
## Registry Trigger
**Use when**
- Changed installed-client behavior needs proof across application lifecycle, operating-system integration, installation state, device configuration, or accessibility settings.
**Do not use when**
- The work is a pure backend, API-contract, component-only browser, or general test-portfolio decision without an installed-client risk.
## Skill Role
Own client interruption, artifact, environment, oracle, and cleanup decisions; exclude general strategy, release, platform, and accessibility-conformance decisions.
## High-Value Rules
- Derive the smallest client matrix for the named failure.
- For the named client failure, bind its oracle to clean state and a release-equivalent artifact.
- Select `client-test-matrix.md` only when client dimensions compete.
## Anti-Patterns
- Local success substituted for evidence of the client application testing contract.
## Stop Conditions
Stop without the matrix, artifact, OS control, or cleanup authority. Record skipped hardware, versions, accessibility, and destructive-install states as limits.
## Output Contract
- Client-test decision with risk matrix; interruption and activation cases; permission and connectivity transitions; artifact and data states; environment coverage; oracles and cleanup; unavailable scope and proof limits.
