v2.0.0 — COMPOSE + OBSERVE

The roadmap capstone. This release also ships the MEMORY primitive from [1.3.0] below, which was prepared but never tagged — 2.0.0 carries it to a published release.

Added

• COMPOSE primitive (#39) under src/compose/ — all composition patterns as pure async combinators: sequential · parallel · mapPattern · reducePattern · conditional(when, then, else?) · loop(body, until, maxIterations).
• dagLayers(nodes) — DAG resolution: orders depends_on into parallelizable layers; throws on a cycle or an unknown dependency.
• OBSERVE primitive (#39) under src/observe/ — a local-first observability layer:
  • checkAlerts(metrics, rules) — threshold alerting rules (> >= < <= == !=) → fired alerts with value + severity, routable through the EventBus.
  • visualise(pipeline, { format }) — an ASCII or Mermaid diagram of a pipeline (trigger → steps + events).
  • abTest(scoreA, scoreB) — compare two skill-version judge scores → { winner, delta }.
• CLI: skillweave visualise <pipeline.yaml> [--mermaid].
• src/index.ts re-exports the COMPOSE + OBSERVE surface.

Notes

• Deferred (documented): the hosted observability dashboard and live alert/webhook delivery (network — a host responsibility; alerts route through the EventBus), orchestrator-level DAG auto-execution, and published performance benchmarks.
