# HyperTwist Phase 6R-E whisper.cpp speech transcript preparation packet

Created on `2026-05-21`

## Status

- historical same-day preparation authority
- bounded post-Phase-`6R-D` preparation slice
- the first bounded implementation slice now lands separately under:
  - `docs/arch/HYPERTWIST_PHASE6R_E_WHISPER_CPP_SPEECH_TRANSCRIPT_IMPLEMENTATION_PACKET_2026-05-21.md`

## Purpose

This packet freezes the next widening order after the landed `Phase 6R-D` `roice3/MagicTile`
tiling-topology slice.

The open task was:

- define the first bounded source-backed widening packet for `ggml-org/whisper.cpp` as the
  retained `Phase 6R-E` speech transcript session boundary

It is not:

- a full `whisper.cpp` row transplant
- a live microphone capture or device-permission packet
- a model checkout or downloadable payload-shipping packet
- a `SYSTRAN/faster-whisper` Python orchestration packet
- a `rhasspy/piper` or `coqui-ai/TTS` voice-output packet
- a broad “voice assistant platform” packet

## Current authority basis

This preparation packet stands on already-closed authority:

- `docs/HYPERTWIST_PHASE_0R_PACKET_0R_A_EVALUATION_2026-05-12.md`
- `docs/HYPERTWIST_PHASE_2R_PACKET_2R_A_OWNERSHIP_AND_ACCEPTANCE_CONTRACT_2026-05-13.md`
- `docs/REPO_LICENSE_TRACKING.md`
- `docs/arch/HYPERTWIST_PHASE6R_D_MAGICTILE_TILING_TOPOLOGY_IMPLEMENTATION_PACKET_2026-05-21.md`

The key accepted routing facts are:

- `ggml-org/whisper.cpp` is the retained offline STT donor immediately after the landed `6R-D`
  slice
- earliest widening route is `Phase 6R / Packet 6R-E`
- the retained donor value there is:
  - speech session configuration
  - bounded VAD policy
  - utterance-envelope shaping
  - transcript-segment and transcript-result structure
  - service-health / sidecar-boundary shaping
- ownership denied there is:
  - do not let the row absorb microphone capture or permission shell ownership
  - do not let the row absorb downloadable model, payload, or voice-asset review
  - do not widen into Python orchestration that belongs with `SYSTRAN/faster-whisper`
  - do not widen into TTS or broad voice-output ownership
  - do not widen into a broad assistant platform

## Why this was the next packet

The earlier retained queue heads were already landed:

- `Phase 6R-A` `HactarCE/Hyperspeedcube`
- `Phase 6R-B` `kkoomen/qbr`
- `Phase 6R-C` `vivaansinghvi07/rubix-cube-solver`
- `Phase 6R-D` `roice3/MagicTile`

That advanced the live queue to:

- `Phase 6R-E` `ggml-org/whisper.cpp`

with the later adjacent retained rows ordered behind it:

- `Phase 6R-F` `SYSTRAN/faster-whisper`
- `rhasspy/piper`
- `coqui-ai/TTS`

## Required result

The source-backed control pass for this packet is now complete.

The first actual `6R-E` implementation packet should:

- use the retained `0R-A` and `2R-A` authority surfaces plus the inspected `whisper.cpp` source
  basis
- define one bounded retained slice from `whisper.cpp`
- keep the slice inside the accepted speech-input seam
- widen only the first transcript-session family that can stand on its own without dragging in
  capture-shell, model-shipping, or voice-output scope
- explicitly state which neighboring retained rows stay closed in that packet

## Source-backed retained basis

The queue-head decision is now source-backed rather than README-only.

Inspected retained donor basis:

- `README.md`
- `include/whisper.h`
- `examples/server/server.cpp`

Inspected first-party receiving basis:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistRecognition/HyperTwistRecognitionTypes.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistRecognition/HyperTwistVisionClient.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingCompanionLibrary.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingCompanionLibrary.cpp`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingTypes.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingSubsystem.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingSubsystem.cpp`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistBootstrap/HyperTwistContractLibrary.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistBootstrap/HyperTwistContractLibrary.cpp`

## Narrowed 6R-E slice decision

The first widening slice was fixed as:

1. speech transcript session boundary above the existing listening lifecycle

not as the broader speech-input or voice platform.

That narrowed slice covers:

- first-party speech VAD policy
- first-party speech session configuration
- first-party utterance envelope
- first-party transcript segment and transcript result
- first-party speech-service health contract
- first-party companion speech session state
- contract-library sample session config and transcript outputs
- direct-donor speech client seam with mock and HTTP-sidecar implementations
- active companion open / submit / close transcript-session handling
- focused automation coverage

## Deferred neighboring families

The first `6R-E` implementation packet must keep these capability families closed:

- live microphone capture shell
- device-permission shell
- downloadable model or payload shipping
- Python orchestration, batching, or hotword service-layer work that belongs with
  `SYSTRAN/faster-whisper`
- TTS or voice-output ownership
- broad “voice assistant platform” scope

Why this slice is first:

- `whisper.cpp` exposes the strongest narrow retained seam at bounded offline transcription with
  VAD-aware session and transcript shape
- current first-party code already has a companion listening lifecycle but lacked an owned
  transcript-session contract and sidecar boundary
- keeping model, payload, and voice decisions outside this packet preserves swapability and cleaner
  legal review

## Out of scope for the first 6R-E packet

- live microphone capture
- downloadable model checkout or packaging
- TTS / voice output
- `faster-whisper` Python service orchestration
- `piper` or `coqui-ai/TTS`
- broad assistant or narration platform work

## Acceptance criteria

- the packet records why the live queue advanced from landed `6R-D` to `6R-E`
- the packet records that the first `6R-E` widening slice is the speech transcript session
  boundary only
- the packet states exact out-of-scope families for the first `6R-E` pass
- the packet keeps the speech-lane legal sequencing guard visible:
  - keep code-license judgments separate from model, voice, and payload-license review
- the packet leaves Python orchestration and voice-output rows deferred behind the landed slice

## Validation checklist

1. confirm the landed `Phase 6R-D` packet is the consumed prior queue head
2. confirm the retained `whisper.cpp` seam narrows cleanly to the transcript-session contract and
   sidecar boundary
3. confirm the next implementation packet is framed as bounded source-backed widening rather than a
   broad speech-platform transplant

That is the packet.
