@Mrgoudan Mrgoudan released this 10 Jul 15:55
v0.2.0
0e9019c

The industrialization release. Schema v2 (auto-migrates existing roots).

Highlights

  • Fan-out/join: fanout.emit runs a step per list item and fires a join event exactly once when every spawned task is terminal — crash/retry-safe barriers with truthful counts.
  • Definition versioning: tasks are stamped with the workflow definition hash; editing YAML under a mid-flight task parks it for a clean re-run instead of replaying old state through a new graph.
  • Timed triggers: schedule: fires events once per window — restart-safe cursor, no catch-up storms.
  • HTTP front door: built-in dashboard + JSON API + POST /api/emit, bearer-token auth, loopback-safe defaults.
  • Record/replay: every agent verdict is archived; --replay-from ROOT re-runs whole pipelines answering LLM steps from recordings — deterministic, token-free CI that fails loudly on prompt drift.
  • Pack-tunable retry policy: retry: in project.yaml retunes error classes or defines new ones for pack block outcomes.
  • Chaos-tested: randomized kill -9 schedules prove convergence and bounded side effects. 169 tests, stdlib only.

Also: MIT license, CI (Linux/macOS × Python 3.9–3.13), migration guides for Celery/cron/Airflow/LangGraph/Temporal in docs/COMING_FROM.md.
