# Telemetry Module Charter

## Mission
- Provide deterministic telemetry context, propagation, and metrics outputs.

## Responsibilities
- Propagate trace, tenant, and correlation context across services.
- Implement redaction, sampling, and metrics aggregation.
- Keep telemetry output stable and offline-friendly.

## Required Reading
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/telemetry/architecture.md
- docs/modules/telemetry/guides/telemetry-standards.md

## Working Agreement
- Use TimeProvider and IGuidGenerator for timestamps and IDs.
- Use invariant formatting for numeric and date outputs.
- Avoid external network dependencies in core telemetry paths.

## Testing Strategy
- Unit tests for context propagation, redaction, and metrics calculations.
- Determinism tests for sampling windows and output ordering.
