# A2 Stage1 Operatorized Entropy Head Refinement

Use this skill when the current truthful next move is one bounded A2-only
refinement pass on `correlation_diversity_functional`, with the stripped
landing failure already established and the remaining question narrowed to
helper-decomposition / term-surface control.

## Purpose

- keep the Stage-1 head family in A2 instead of drifting back into A1
- decide whether any thinner admissible source-anchored read emerges
- preserve the blocker explicitly when the direct target still does not land

## Execute Now

1. Load:
   - `system_v4/a2_state/audit_logs/A2_REFINEMENT_FOR_A1_STRIPPED_LANDING__CORRELATION_DIVERSITY_FUNCTIONAL__2026_03_20__v1.md`
   - `system_v3/a2_state/A2_WORKER_LAUNCH_HANDOFF__STAGE1_OPERATORIZED_ENTROPY_HEAD__2026_03_13__v1.json`
   - `system_v3/a2_state/A2_UPDATE_NOTE__STAGE1_OPERATORIZED_ENTROPY_HEAD_GROUNDING__2026_03_17__v1.md`
   - `system_v3/a2_state/A2_TO_A1_IMPACT_NOTE__STAGE1_OPERATORIZED_ENTROPY_HEAD_GROUNDING__2026_03_17__v1.md`
   - `system_v3/a2_state/A2_TO_A1_DISTILLATION_INPUTS__v1.md`
   - `system_v3/a2_state/NEXT_VALIDATION_TARGETS__v1.md`
   - `system_v3/a1_state/A1_ENTROPY_STRUCTURE_DECOMPOSITION_CONTROL__v1.md`
   - `system_v3/a1_state/A1_ENTROPY_BRIDGE_HELPER_DECOMPOSITION_CONTROL__v1.md`
2. Decide whether a thinner admissible source-anchored read exists that changes the current blocked landing state.
3. Emit:
   - `system_v4/a2_state/audit_logs/A2_STAGE1_OPERATORIZED_ENTROPY_HEAD_REFINEMENT__CORRELATION_DIVERSITY_FUNCTIONAL__2026_03_20__v1.md`

## Quality Gates

- Stay A2-only; do not perform A1 translation or packaging in this pass.
- Do not treat route validity or family interest as enough for A1 promotion.
- Do not reopen more route proof when the doctrine says the route is already real.
- If no thinner admissible landing emerges, preserve the blocker explicitly and point at helper-decomposition control.
