# HyperTwist Phase 6R-AW learned-search sequence policy and search budget implementation packet

Date: `2026-05-31`

## Outcome

`Phase 6R-AW` is now landed locally as a bounded first-party refinement above
the already landed `Phase 6R-AV` learned-search experimentation lane.

## What landed

The current code now owns:

- a first-party learned-search sequence-policy contract
- a first-party learned-search search-budget boundary
- runtime-library accessors for both
- focused automation coverage for the new contract and boundary

## Code surfaces

- `HyperTwistTrainingLearnedSearchLibrary.h/.cpp`
  - new sequence-policy and search-budget contracts inside the existing
    learned-search bundle
- `HyperTwistTrainingRuntimeLibrary.h/.cpp`
  - bundle accessors for the new learned-search surfaces
- `HyperTwistLearnedSearchPhase6RAWSequenceBudgetContractTest.cpp`
  - focused automation for sequence-policy and search-budget assertions

## Boundedness preserved

This packet does **not** claim:

- live replay/notation ownership
- general scramble-registry ownership
- correctness/performance oracle ownership
- live solve explanation ownership
- deployed model serving
- broad ML platform ownership

The slice remains an internal first-party experimentation refinement only.

## Canon impact

The HyperTwist canon now records:

- `Phase 6R-AV` learned-search experimentation is landed
- `Phase 6R-AW` sequence-policy and search-budget refinement is also landed
- live recognition/reconstruction ownership still stays with `qbr` and
  `rubix-cube-solver`
- correctness/performance oracle ownership still stays with `brownan` and
  `efrantar`
