- Session is root (not Mission): Field Session → Mission → Asset → Observation... - Event Sourcing: never overwrite status, status is projection of history - Artifact Registry: first-class object with id, type, version, hash, lineage - Decision Case immutability: Review → Revision → Approved Version (like Git) - Review Task: Assigned → Reviewed → Approved → Closed - Processing Graph: nodes not hardcoded chain, swap models without changing rest - Data Quality as domain: Blur, Duplicate, Bad GPS, Low Resolution, etc. - Decision Case comparison: show exactly what changed, which evidence, model, human - Golden Missions + Golden Datasets: two levels - Domain Event Viewer: timeline (09:42 Mission Created, 09:43 Video Uploaded...) - KPI: Verified Decision Throughput (verified decisions per day) - Architecture Principle: 'Produces verified Decision Cases through reproducible and traceable pipeline' Updated PR-001 Domain Model: - Added FieldSession (root) - Added Artifact interface - Added Event sourcing types - Session ID format: session_YYYYMMDD_NNNNNN - Updated API to include /sessions endpoints Rationale: Three fundamental objects (Session, Artifact, Event) make the rest natural. Scalable, auditable, well-suited for public sector traceability requirements.
