rivumi now connects events.jsonl to a deterministic reducer, CLI timeline, canonical JSON, SDK replay, and safe event-point forks. Forking never replays prior tools or model calls; provider/live-runtime validation, redaction, and richer replay hooks remain open.
Observability is a first-class capability, not logging added after the fact: a structured trace connects FlowRun→StepRun→SkillInvocation→ProviderCall→ToolInvocation→GuardResult→EvidenceItem→ArtifactVersion. The Evidence Store traces every claim back to its source, excerpt, citation, confidence, and conflicts. Artifact versioning supports approve/reject/regenerate without deleting history. Context Snapshots allocate token budgets by category and record automatic compression when a block exceeds its budget. Procedural, episodic, and semantic memory can be written only through proposals reviewed by a human.
