v0.9.0

v0.9.0

v0.9.0 focuses on tighter task contracts, safer follow-up work, stronger evidence handling, and more reliable batch/worktree execution.

Highlights

• Explicit Change Intent
  Delegated tasks can now declare whether changes are required, optional, or forbidden, independently of file scope.

• Worker Continuation
  Eligible tasks can resume the same worker thread for one bounded follow-up while preserving the original contract and verification rules.

• Bounded Repair
  Tasks can optionally receive one conservative same-thread repair attempt after a qualifying authoritative verification failure.

• Stronger batch and worktree lifecycle
  Parallel execution now has improved worktree isolation, lease ownership, cleanup, integration evidence, and failure handling.

• Better verification and reconciliation
  Structured worker failure causes are preserved, while authoritative verification can safely resolve the narrow verification-only contradiction case without hiding the original worker claim.

• Parent and cost foundations
  Added explicit parent-identity provenance, billing-context separation, caller-supplied rate cards, observed usage accounting, and safe unavailable states without guessing account or pricing information.

• Improved documentation and setup guidance
  Documentation was consolidated around clearer sources of truth, the setup/update lifecycle was simplified, and feature acceptance now has a dedicated evidence and confidence ledger.

Reliability

This release also includes additional hardening around:

• sequential and parallel batch evidence
• integration conflict reporting
• retained-worktree continuation
• lease renewal and cleanup
• cancellation lifecycle
• activity and privacy reporting
• live-model structured-output compatibility
