 ## Runtime Observability
 
 Treat privacy-safe runtime observability as part of implementing or changing stateful, asynchronous, fallible, or lifecycle-oriented behavior. Identify the meaningful success, failure, cancellation, recovery, and state-transition boundaries before handoff, and emit concise AppLogger events owned by the artifact that implements them. Dependency declaration or target linkage alone does not satisfy this requirement.
 
 Every ThatFactory package log starts with its canonical emoji and uses its own stable subsystem. Never log credentials, account or record identifiers, share URLs, captured content, images, or other user-generated values as public metadata. Keep pure values and utilities silent when they have no meaningful diagnostic event; record that deliberate decision in the implementation handoff instead of adding initializer or property-access noise. Follow [Logging](AgentGuidelines/Guidelines/Logging.md) for ownership, privacy, severity, message design, and tests.
