We're excited to announce IntentusNet v1.3.0, bringing execution recording, deterministic replay, and improved stability to the runtime.

What's New​

Execution Recording & Replay​

The headline feature of v1.3.0 is the execution recording and replay system:

# Enable recording
runtime = IntentusRuntime(enable_recording=True)

# Execute
response = runtime.router.route_intent(envelope)
execution_id = response.metadata["execution_id"]

# Later: replay returns exact same output
engine = ReplayEngine(store.load(execution_id))
result = engine.replay()  # No model calls, exact output

Every execution is now captured with:

  • Stable envelope hash for integrity
  • Step-by-step event trace
  • Complete final response
  • Replayability status

Determinism Hardening​

We've strengthened determinism guarantees:

  • Agent ordering now uses explicit nodePriority field
  • Sequence numbers replace timestamps for event ordering
  • Canonical JSON ensures consistent hashing

Public API Cleanup​

The public API has been refined:

  • Clear separation between public and internal modules
  • Type hints throughout
  • Comprehensive docstrings
  • Stable export list in __init__.py

New replayableReason Field​

When a record can't be replayed, the reason is now explicit:

{
  "header": {
    "replayable": false,
    "replayableReason": "execution_incomplete"
  }
}

Breaking Changes​

Removed​

  • IntentRouter.route() - use route_intent() instead
  • Legacy envelope format v1.x

Changed​

  • AgentDefinition.priority renamed to nodePriority for clarity
  • Event timestamps are now supplementary; sequence numbers are authoritative

Upgrade Guide​

  1. Update imports:

    # Old
    from intentusnet.router import IntentRouter

    # New
    from intentusnet import IntentRouter

  2. Update agent definitions:

    # Old
    AgentDefinition(priority=10, ...)

    # New
    AgentDefinition(nodePriority=10, ...)

  3. Enable recording for replay:

    runtime = IntentusRuntime(enable_recording=True)

What's Next​

For v1.4.0, we're planning:

  • Async routing support
  • Built-in timeout handling
  • WAL-backed persistence
  • Additional execution stores
