v1.4.0

What's New in v1.4.0

Drift Detection (verify check)

• Git-based drift detection compares decision timestamps against file modification times
• Detects stale decisions where affected files were modified after the decision was recorded
• Handles superseding decisions — a newer decision in the same domain/scope suppresses stale warnings
• Gracefully skips when git is unavailable

Constraint Checking (verify check)

• Executes check_command from constraint blackboard entries and compares output against expected
• Shell operator injection protection — rejects commands containing |, &&, ||, ;, $(), backticks, >, <
• 5-second timeout per command
• Reports pass/warn/fail with detailed actual vs expected output

Example Projects

• Claude Agent SDK example (examples/claude-agent-sdk/) — Python code review agent demonstrating the full Twining lifecycle: assemble → review → post findings → decide → handoff
• Strands Agents example (examples/strands-agents/) — Two coordinating Strands agents sharing state through Twining for collaborative code review

Federation Design

• docs/FEDERATION_DESIGN.md — comprehensive design document for multi-project federation covering hub-and-spoke model, query federation, decision propagation, consistency model, and 4 implementation options
