Summary
AI summaryAdds default-off runtime-owned usage governance with config and state artifacts
Full changelog
[0.15.4] - 2026-04-27
0.15.4 adds default-off runtime-owned usage governance so operators can let
Millrace automatically pause between stages when configured token or subscription
quota limits are reached.
Added
- Added
[usage_governance]config with runtime token rules, optional
subscription quota rules, auto-resume behavior, and next-tick apply
boundaries. - Added durable usage governance state and ledger artifacts under
millrace-agents/state/. - Added runtime-owned pause source tracking so operator pauses and governance
pauses can coexist without overwriting each other. - Added status and live daemon monitor output for active usage blockers,
subscription telemetry degradation, governance pause, and governance resume
events.
Changed
- Runtime ticks now evaluate usage governance before launching a stage and after
persisting a stage result, preserving the between-stage execution boundary. millrace control resumenow clears operator pause intent without bypassing an
active usage-governance blocker.- Stage-result token usage can be reconciled back into the governance ledger
after restart if a ledger write was missing.
