# A2 Entropy Bridge Helper Decomposition Control

Use this skill when the truthful next move is one bounded A2-only pass that
freezes the helper-decomposition barrier for
`correlation_diversity_functional`, after the Stage-1 entropy-head refinement
already preserved the blocker explicitly.

## Purpose

- confirm the real blocker is helper decomposition under current lower-loop semantics
- keep compound bridge heads in proposal/control space instead of faking stripped admission
- preserve colder witness execution as the current executable default

## Execute Now

1. Load:
   - `system_v4/a2_state/audit_logs/A2_STAGE1_OPERATORIZED_ENTROPY_HEAD_REFINEMENT__CORRELATION_DIVERSITY_FUNCTIONAL__2026_03_20__v1.md`
   - `system_v3/a1_state/A1_ENTROPY_BRIDGE_HELPER_DECOMPOSITION_CONTROL__v1.md`
   - `system_v3/a1_state/A1_ENTROPY_STRUCTURE_DECOMPOSITION_CONTROL__v1.md`
   - `system_v3/a1_state/A1_ENTROPY_EXECUTABLE_ENTRYPOINT__v1.md`
   - `system_v3/a2_state/A2_TO_A1_DISTILLATION_INPUTS__v1.md`
   - `system_v3/a2_state/NEXT_VALIDATION_TARGETS__v1.md`
2. Decide whether the repo-held doctrine confirms:
   - compound bridge heads remain proposal/control-only
   - executable work stays on colder witnesses
   - alias/component-ladder work remains deferred
3. Emit:
   - `system_v4/a2_state/audit_logs/A2_ENTROPY_BRIDGE_HELPER_DECOMPOSITION_CONTROL__CORRELATION_DIVERSITY_FUNCTIONAL__2026_03_20__v1.md`

## Quality Gates

- Stay A2-only; do not perform A1 stripped translation or cartridge packaging.
- Do not claim `correlation_diversity_functional` has earned direct executable admission.
- Do not reopen alias-first or component-ladder work as the default route unless the cited doctrine explicitly changes.
- If the doctrine does not line up, fail closed with explicit missing evidence.
