# HyperTwist Phase 6R-AV learned heuristic search and ADI experimentation implementation packet

Date: `2026-05-31`

## Outcome

`Phase 6R-AV` is now landed locally as a bounded first-party learned-search and
`ADI` experimentation seam grounded in the retained
`yakupbilen/drl-rubiks-cube` benchmark.

## What landed

The current code now owns a bounded first-party experimentation slice through:

- donor-package references for compact state, `ADI`, search, and small
  value-network benchmark surfaces
- a first-party learned-search experiment profile contract
- a first-party `ADI` generation and target-preparation boundary
- a first-party offline neural search benchmark boundary
- a first-party attribution boundary that keeps the donor row benchmark-only
- runtime-library accessors for the new bundle and contracts
- focused automation coverage for bundle, experiment-profile, and boundary
  resolution

## Code surfaces

- `HyperTwistTrainingLearnedSearchLibrary.h/.cpp`
  - new bundled benchmark-reference and first-party experimentation library
- `HyperTwistTrainingRuntimeLibrary.h/.cpp`
  - bundle getters and contract/boundary accessors
- `HyperTwistLearnedSearchPhase6RAVExperimentationContractTest.cpp`
  - focused reference-bundle and boundary contract coverage

## Boundedness preserved

This packet does **not** claim:

- live camera recognition ownership
- committed-face reconstruction ownership
- correctness/performance oracle ownership
- generalized solver-backend ownership
- deployed product-side ML serving
- broad model-training platform ownership

The slice remains a narrow first-party experimentation layer above the retained
benchmark packages.

## Canon impact

The HyperTwist canon now records:

- `yakupbilen/drl-rubiks-cube` still remains benchmark-grounded
- `Phase 6R-AV` is the only landed first-party reopening from that row
- `qbr` and `rubix-cube-solver` remain live recognition/reconstruction owners
- `brownan` and `efrantar` remain correctness/performance oracle owners
