ADR 0005: Narrow v1 scheduling

Status: superseded for scheduling and control flow by ADRs 0008 through 0011, 2026-07-24.

V1alpha1 schedules a sequential DAG in declaration order and integrates typed actions/tools, local packs, MCP 2025-11-25, and A2A 1.0. maxConcurrency greater than one is rejected.

The original decision excluded parallel execution, loops, and routing until their deterministic semantics existed. ADRs 0008, 0010, and 0011 now define those contracts. Sub-workflows, teams/handoffs, automatic reconnection/resubmission, executable plugin ABIs, and registries remain separate product decisions.
