# HyperTwist Phase 6R-AP faster-whisper batch-window and prompt/retrieval tuning preparation packet

Created on `2026-05-31`

## Status

- first-party HyperTwist packet
- bounded permissive `Phase 6R-AP` preparation/control slice

## Purpose

This packet scopes the next justified owned widening above the already landed
`Phase 6R-F` `SYSTRAN/faster-whisper` orchestration profile.

The granted slice is:

- batch-collection window metadata for the Python transcription service lane
- prompt-routing mode metadata above the existing prefix and hotword posture
- retrieval-hint lane metadata above the existing command-hint seam
- bounded transcript-result backfill for those tuning surfaces
- bounded service-health capability exposure for that tuning family

It is not:

- a full `faster-whisper` row transplant
- top-level provider/session ownership
- BYOK/profile custody
- microphone capture or device-permission ownership
- downloadable model or payload shipping
- worker-process takeover
- TTS or broad voice-output ownership
- broad assistant-platform scope

## Current authority basis

This control pass stands on:

- `docs/REPO_LICENSE_TRACKING.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/ROADMAP.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/FEATURE_REGISTRY.md`
- `docs/arch/HYPERTWIST_PHASE6R_F_FASTER_WHISPER_TRANSCRIPTION_ORCHESTRATION_IMPLEMENTATION_PACKET_2026-05-21.md`

The preserved owners do not change:

- first-party HyperTwist remains the top-level provider/session owner
- `ggml-org/whisper.cpp` remains the native speech-input runtime owner
- `SYSTRAN/faster-whisper` remains bounded to Python orchestration and tuning
  metadata rather than broader speech-platform ownership

## Granted family

The bounded `Phase 6R-AP` slice may land:

1. batch-window tuning metadata in the orchestration profile
2. prompt-routing mode and retrieval-context lane metadata in the orchestration
   profile
3. bounded retrieved-hint count and applied-hint metadata in transcript results
4. mock and HTTP speech-client backfill for those tuning surfaces
5. bounded service-health capability exposure for:
   - batch-window tuning
   - prompt-routing profiles
   - retrieval-hint augmentation
6. focused automation for:
   - session-config tuning defaults
   - transcript-result tuning metadata
   - service-health capability exposure

The packet must stay out of:

- worker-process management or queue-ownership takeover
- actual model checkout, payload packaging, or download ownership
- provider-profile custody or custom-endpoint ownership
- voice-output widening

## Validation target

Use the documented validation split:

- safe VPS-side source checks first
- when Unreal validation is sensible and the instance is on the VPS without
  `UnrealEditor`, use the Windows reverse-SSH lane documented in the sensitive
  runbook
- if the Windows checkout lags the VPS source state, say that explicitly and
  do not claim packet coverage for missing Windows-side files

## Queue effect

If this packet lands cleanly, `SYSTRAN/faster-whisper` remains the bounded live
owner for Python orchestration metadata and gains the next narrow tuning seam
without reopening provider, payload, or voice-output lanes.
