# HyperTwist Phase 6R-AR coqui-ai/TTS downloadable voice/model review boundary implementation packet

Created on `2026-05-31`

## Status

- first-party HyperTwist packet
- bounded boundary-sensitive `Phase 6R-AR` implementation slice

## Purpose

This packet lands the next narrower bounded slice from the retained `coqui-ai/TTS` voice-output row.

The landed slice is:

- first-party downloadable voice/model review boundary above the existing advanced narration seam

It is not:

- a downloadable voice/model shipping packet
- a runtime model-download packet
- a voice-conversion packet
- a broad playback runtime packet
- a broad voice-platform packet

## Current authority basis

This implementation packet stands on:

- `docs/REPO_LICENSE_TRACKING.md`
- `docs/ops/HYPERTWIST_MPL_DISTRIBUTION_PLACEMENT_CHECKLIST_2026-05-25.md`
- `docs/arch/HYPERTWIST_PHASE6R_H_COQUI_TTS_ADVANCED_NARRATION_IMPLEMENTATION_PACKET_2026-05-22.md`
- `docs/arch/HYPERTWIST_PHASE6R_AR_COQUI_TTS_DOWNLOADABLE_VOICE_MODEL_REVIEW_BOUNDARY_PREPARATION_PACKET_2026-05-31.md`

The retained owner remains:

- `coqui-ai/TTS`

The top-level provider and companion contract owner does not change here:

- first-party HyperTwist remains the provider-neutral and companion-contract owner
- this packet keeps `coqui-ai/TTS` bounded to advanced voice/model review metadata only

## Landed scope

The current code now owns a retained advanced voice/model review boundary through:

- retained recognition contract types for:
  - `FHyperTwistVoiceModelReviewProfile`
  - `FHyperTwistVoiceModelReviewDescriptor`
  - `FHyperTwistVoiceServiceHealth`
- sample advanced review-profile, review-descriptor, and service-health outputs in:
  - `UHyperTwistContractLibrary`
- bounded mock and provider-backed voice-client review metadata in:
  - `UHyperTwistMockVoiceClient`
  - `UHyperTwistHttpVoiceClient`
- focused automation coverage in:
  - `HyperTwistCoquiPhase6RARVoiceModelReviewContractTest.cpp`

## Why this is still intentionally bounded

This packet closes the explicit advanced review gap without widening into shipping, playback, or conversion ownership.

Still deferred:

- bundled voice asset shipping
- runtime model download
- voice conversion
- broad playback runtime ownership
- viseme / gesture runtime integration
- broad assistant-platform scope

## Validation

Build validation:

- `Build.bat UnrealHyperTwistEditor Win64 Development -Project='C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject' -WaitMutex -NoHotReloadFromIDE`

Focused automation validation:

- `Automation RunTests HyperTwist.Permissive.Coqui.Phase6R.AR`

Regression automation validation:

- `Automation RunTests HyperTwist.Permissive.Coqui.Phase6R.H`
- `Automation RunTests HyperTwist.Permissive.Piper.Phase6R.AQ`
- `Automation RunTests HyperTwist.Permissive.FasterWhisper.Phase6R.AP`

Expected covered tests:

- `VoiceModelReviewProfile`
- `AdvancedNarrationReviewAlignment`
- `ProviderBackedReviewFallback`
- existing `Phase6R.H`, `Phase6R.AQ`, and `Phase6R.AP` regression slices

## Queue effect

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

`coqui-ai/TTS` remains only partially incorporated:

- landed now:
  - downloadable voice/model review profile
  - supported advanced voice-model review descriptors
  - advanced voice service-health review metadata
- still deferred:
  - bundled voice asset shipping
  - runtime model download
  - voice conversion
  - broad playback runtime ownership
  - viseme / gesture runtime integration
  - broad assistant-platform scope

The next clean move is:

- another retained-row seam only if it is comparably narrow and clearly bounded

Keep the future sequencing guards visible:

- `coqui-ai/TTS`
  - keep actual shipping and conversion separate from the landed review boundary
- the speech lane
  - keep code-license judgments separate from model, voice, and payload review
