Refinement: reversible harness-state adaptation

/refine reviews trajectory evidence and proposes small edits to prompt notes, memories, skill descriptions, or subagent specifications. Changes apply at turn boundaries, are logged with refinement IDs, and can be rolled back. The immutable base system prompt is outside the surface, and refinement can optimize the wrong objective.

Changes apply at turn boundaries, are logged with refinement IDs, and can be rolled back. The immutable base system prompt is outside the surface, and refinement can optimize the wrong objective.

  • S001 supports the route's current claim set.

  • S001 supports the route's current claim set.
  • S003 supports the route's current claim set.
  • S088 supports the route's current claim set.

Rollback by refinement ID

Rollback is part of the design, not an afterthought. Record a refinement ID, confirm the diff, then revert or narrow the change when the new behavior regresses.

Persistence scope ambiguity

What this does not mean

This feature or concept does not imply a sandbox, a guarantee of success, or a claim that the harness is superior in every scenario. It only means the documented behavior exists in v0.7.1.
