# Metrics Tests Agent Charter

## Mission
- Validate KPI models, collector logic, and trend calculations for metrics.

## Responsibilities
- Keep tests deterministic and independent of local time zones.
- Avoid nondeterministic IDs or timestamps in assertions.

## Required Reading
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md

## Working Directory & Scope
- Primary: src/__Libraries/__Tests/StellaOps.Metrics.Tests
- Allowed shared projects: src/__Libraries/StellaOps.Metrics

## Testing Expectations
- Cover KPI trend calculations and label normalization.
- Use fixed timestamps and deterministic inputs.

## Working Agreement
- Update sprint status in docs/implplan/SPRINT_*.md and local TASKS.md.
- Keep outputs deterministic and avoid non-ASCII logs.
