cep.events.v2.2

This document specifies the streaming event model for cep.events.v2.2.

Core Requirement​

A streaming sequence MUST be able to reconstruct a final cep.envelope.v2.2 result.

Event Categories (Draft)​

  • start: execution started
  • delta: incremental output delta (provider streaming chunk)
  • meta: incremental meta updates (subset of cep.envelope meta)
  • error: error signal (may appear before end)
  • end: terminal event, MUST include result which conforms to cep.envelope.v2.2

Minimal Fields​

Every event MUST include:

  • type
  • version (MUST be "2.2")
  • timestamp_ms
  • module

Optional context fields:

  • provider

Open Questions​

  • Transport framing (SSE vs NDJSON) and the canonical mapping per transport
  • Ordering guarantees for delta vs meta
