# HyperTwist Phase 6R-O qbr webcam UI shell implementation packet

Created on `2026-05-22`

## Status

- first-party HyperTwist packet
- bounded permissive `Phase 6R-O` implementation slice

## Purpose

This packet lands the current retained `qbr` webcam shell family:

- first-party classic-cube webcam shell profile and shell-state composition

It is not:

- a full `qbr` row transplant
- a multilingual solve shell packet
- a bundled-font redistribution packet
- a multi-face correction or explanation packet
- a `rubix-cube-solver` browser-shell packet

## Current authority basis

This implementation packet stands on:

- `docs/REPO_LICENSE_TRACKING.md`
- `docs/ops/HYPERTWIST_CROSS_LANE_AUTHORITY_HIERARCHY_AND_RECONCILIATION_2026-05-20.md`
- `docs/arch/HYPERTWIST_PHASE6R_O_QBR_WEBCAM_UI_SHELL_PREPARATION_PACKET_2026-05-22.md`

The retained owner remains:

- `kkoomen/qbr`

The top-level product shell owner does not change here:

- first-party HyperTwist remains the broader recognition-session and product-shell owner
- this packet keeps `kkoomen/qbr` bounded to the narrower `A1 / R1 / F2` classic-cube webcam
  shell slice

## Landed scope

The current code now owns a retained `qbr` webcam shell contract through:

- first-party `HyperTwistRecognition` contract types for:
  - shell action bindings
  - shell panel layout
  - shell profile definition
  - shell state readout
- recognition session config defaults for:
  - first-party classic-cube webcam shell profile id
  - classic-cube webcam shell profile definition
- first-party preview and commit result shaping for:
  - scanned-side count
  - captured-face ids
  - target-face hint
  - last committed face id
  - bounded shell panel visibility
- sample contract routing in:
  - `UHyperTwistContractLibrary`
- active subsystem normalization in:
  - `UHyperTwistTrainingSubsystem`
- focused automation coverage in:
  - `HyperTwistQbrPhase6ROWebcamShellContractTest.cpp`

## Why this is still intentionally bounded

This packet lands the bounded webcam shell seam, but it does not widen into neighboring families or
broader ownership.

Still excluded:

- bundled-font redistribution
- multilingual solve shell ownership
- multi-face reconstruction / correction / explanation ownership
- broad browser shell or recommendation ownership
- `rubix-cube-solver` browser/webcam shell ownership

## Validation

Build validation:

- `C:\Program Files\Epic Games\UE_5.7\Engine\Build\BatchFiles\Build.bat UnrealHyperTwistEditor Win64 Development -Project='C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject' -WaitMutex -NoHotReloadFromIDE`

Focused automation validation:

- `C:\Program Files\Epic Games\UE_5.7\Engine\Binaries\Win64\UnrealEditor-Cmd.exe C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject -unattended -nop4 -nosplash -NullRHI -log -stdout -FullStdOutLogOutput -AbsLog=C:\HyperTwist\UnrealHyperTwist\Saved\Logs\Phase6R-O-Qbr-Verify.log -ReportExportPath=C:\HyperTwist\UnrealHyperTwist\Saved\AutomationReports\Phase6R-O-Qbr-Verify -ExecCmds="Automation RunTests HyperTwist.Permissive.Qbr.Phase6R.O; Quit" -TestExit="Automation Test Queue Empty"`

Regression automation validation:

- `HyperTwist.Permissive.Qbr.Phase6R.B`
- `HyperTwist.Permissive.RubixCubeSolver.Phase6R.C`
- `HyperTwist.Permissive.Hyperspeedcube.Phase6R.N`
- `HyperTwist.CleanRoom.CubeDesk`

Expected covered tests:

- `WebcamShellSessionConfig`
- `WebcamShellPreviewState`
- `WebcamShellCommitState`
- existing `qbr`, `rubix-cube-solver`, `Hyperspeedcube`, and `CubeDesk` regression suites

## Queue effect

This packet consumes the current `Phase 6R-O` implementation slice.

`kkoomen/qbr` remains partially incorporated:

- landed now:
  - classic-cube recognition calibration contract
  - ordered face-observation contract
  - classic-cube webcam shell
- still deferred:
  - bundled-font redistribution and multilingual solve shell
  - multi-face correction / explanation ownership

The next clean move is:

- source-backed `Phase 6R-P` `vivaansinghvi07/rubix-cube-solver` browser/webcam shell
  preparation/control pass

Keep the future sequencing guards visible:

- keep the `qbr` font guard explicit:
  - preserve separate confirmation or replacement before any shipping path redistributes
    `src/assets/arial-unicode-ms.ttf`
- keep the `rubix-cube-solver` browser-shell widening narrow:
  - do not widen directly into bundled `twistysim.min.js` redistribution or broad solve
    explanation/recommendation ownership in the next packet
