+# HyperTwist Phase 6R-U whisper.cpp live microphone capture shell implementation packet
+
+Created on `2026-05-24`
+
+## Status
+
+- first-party HyperTwist packet
+- bounded permissive `Phase 6R-U` implementation slice
+
+## Purpose
+
+This packet lands the next narrower bounded slice from the retained
+`ggml-org/whisper.cpp` speech-input row.
+
+The landed slice is:
+
+- first-party live microphone capture shell profile and session-state boundary
+  above the existing companion speech transcript-session seam
+
+It is not:
+
+- a full `whisper.cpp` row transplant
+- a real device-permission workflow packet
+- a downloadable model or payload-shipping packet
+- a top-level provider/session contract packet
+- a voice-output packet
+- a broad assistant-platform 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_U_WHISPER_CPP_LIVE_MICROPHONE_CAPTURE_SHELL_PREPARATION_PACKET_2026-05-24.md`
+
+The retained owner remains:
+
+- `ggml-org/whisper.cpp`
+
+The top-level provider/session contract owner does not change here:
+
+- first-party HyperTwist remains the provider-neutral owner for the speech
+  provider/session lane
+- `SYSTRAN/faster-whisper` remains the complementary landed Python
+  orchestration donor
+- this packet keeps `ggml-org/whisper.cpp` bounded to the narrower live
+  microphone shell donor slice only
+
+The granted family remains bounded to:
+
+- shell panel and action contract shaping
+- donor-backed microphone shell defaults
+- session open / submit / close shell-state composition
+- speech-health capability exposure for the bounded shell
+
+This packet lands only the first narrower family in that granted set.
+
+## Landed scope
+
+The current code now owns a retained live microphone shell contract through:
+
+- retained recognition contract types for:
+  - `FHyperTwistSpeechShellPanelLayout`
+  - `FHyperTwistSpeechShellActionBinding`
+  - `FHyperTwistSpeechMicrophoneShellProfile`
+  - `FHyperTwistSpeechMicrophoneShellState`
+  - microphone-shell-aware `FHyperTwistSpeechSessionConfig`
+- companion speech session state expansion in:
+  - `FHyperTwistTrainingCompanionSpeechSessionState`
+- sample session-config and service-health outputs in:
+  - `UHyperTwistContractLibrary`
+- direct-donor speech client seam capability exposure in:
+  - `UHyperTwistMockSpeechClient`
+  - `UHyperTwistHttpSpeechClient`
+- active companion shell-state normalization in:
+  - `UHyperTwistTrainingSubsystem`
+- focused automation coverage in:
+  - `HyperTwistWhisperCppPhase6RUMicrophoneShellContractTest.cpp`
+
+## Why this is still intentionally bounded
+
+This packet lands the next donor-backed microphone shell seam, but it does not
+widen into the neighboring retained families.
+
+Still deferred:
+
+- real device-permission workflow
+- native audio-device route ownership beyond bounded shell state
+- downloadable model or payload shipping
+- provider-profile and BYOK custody
+- voice-output ownership
+- broad assistant-platform scope

+# HyperTwist Phase 6R-U whisper.cpp live microphone capture shell preparation packet
+
+Created on `2026-05-24`
+
+## Status
+
+- historical same-day preparation authority
+- bounded post-`Phase 6R-T` control slice
+- the first bounded implementation slice now lands separately under:
+  - `docs/arch/HYPERTWIST_PHASE6R_U_WHISPER_CPP_LIVE_MICROPHONE_CAPTURE_SHELL_IMPLEMENTATION_PACKET_2026-05-24.md`
+
+## Purpose
+
+This packet freezes the next widening order after the landed `Phase 6R-T`
+`MagicTile` transform-aware macro remapping slice.
+
+The open task was:
+
+- define the next bounded source-backed widening packet for
+  `ggml-org/whisper.cpp` as the retained `Phase 6R-U` live microphone capture
+  shell seam
+
+It is not:
+
+- a full `whisper.cpp` row transplant
+- a real device-permission workflow packet
+- a downloadable model or payload-shipping packet
+- a `SYSTRAN/faster-whisper` provider/service rewrite packet
+- a `rhasspy/piper` or `coqui-ai/TTS` voice-output packet
+- a broad assistant-platform packet
+
+## Current authority basis
+
+This preparation packet stands on already-closed authority:
+
+- `docs/REPO_LICENSE_TRACKING.md`
+- `docs/v6_5_deep_manual_pack/HyperTwist/ROADMAP.md`
+- `docs/arch/HYPERTWIST_PHASE6R_T_MAGICTILE_TRANSFORM_AWARE_MACRO_REMAPPING_IMPLEMENTATION_PACKET_2026-05-24.md`
+
+The key accepted routing facts are:
+
+- `ggml-org/whisper.cpp` remains the retained offline STT donor after the
+  already landed `Phase 6R-E` transcript-session slice
+- `SYSTRAN/faster-whisper` remains the complementary landed Python
+  orchestration donor above the existing first-party speech session boundary
+- first-party HyperTwist already owns the top-level provider/session contract,
+  companion listening lifecycle, and speech-session substrate
+- the retained donor value strongest for the next narrow widening is:
+  - VAD-gated streaming-shell defaults
+  - rolling capture-window and keep-window posture
+  - transcript-preview and manual-commit shell cues
+  - health-surface capability exposure for the bounded shell
+- ownership denied here is:
+  - do not widen into real device-permission workflow ownership
+  - do not widen into downloadable model or payload shipping
+  - do not let `whisper.cpp` inherit the top-level provider/session lane
+  - do not widen into voice-output or broad assistant-platform ownership
+
+## Required result
+
+The source-backed control pass for this packet is now complete.
+
+The first actual `6R-U` implementation packet should:
+
+- define one bounded live microphone capture shell slice above the landed
+  transcript-session boundary
+- land a first-party microphone shell profile and session-state surface
+- preserve donor-backed stream defaults as shell metadata rather than a broader
+  runtime takeover
+- add bounded health-surface capability exposure and focused automation
+- explicitly state which neighboring retained families stay closed
+
+## Source-backed retained basis
+
+The queue-head decision is now source-backed rather than README-only.
+
+Inspected retained donor basis:
+
+- `C:\visual_studio_solutions\multi_project\GPT 5.4 HyperTwist parse\49-ggml-org-whisper-cpp-upstream-dossier.md`
+- `C:\Workspaces\HyperTwist\mirrors\permissive\ggml-org\whisper.cpp\examples\stream\stream.cpp`
+- `C:\Workspaces\HyperTwist\mirrors\permissive\ggml-org\whisper.cpp\examples\server\README.md`
+- `C:\Workspaces\HyperTwist\mirrors\permissive\ggml-org\whisper.cpp\include\whisper.h`
+- `C:\Workspaces\HyperTwist\mirrors\permissive\ggml-org\whisper.cpp\tests\test-vad.cpp`
+
+Inspected first-party receiving basis:
+
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistRecognition/HyperTwistRecognitionTypes.h`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistRecognition/HyperTwistSpeechClient.h`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingTypes.h`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingSubsystem.h`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistBootstrap/HyperTwistContractLibrary.cpp`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingSubsystem.cpp`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistRecognition/HyperTwistMockSpeechClient.cpp`
+- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistRecognition/HyperTwistHttpSpeechClient.cpp`
+
+## Narrowed 6R-U slice decision
+
+The next widening slice is fixed as:
+
+1. live microphone capture shell profile and session-state boundary
+
+That narrowed slice covers:
+
+- first-party speech shell contract types for:
+  - shell panel layout
+  - shell action binding
+  - microphone shell profile
+  - microphone shell state
+- donor-backed shell defaults for:
+  - `3000ms` step window
+  - `10000ms` capture window
+  - `200ms` keep window
+  - `0.6` VAD threshold
+  - `100Hz` high-pass threshold
+  - no previous-text carryover by default
+- first-party session-state composition for:
+  - open-state shell activation
+  - utterance preview/commit progression
+  - transcript-preview, speech-gap, and last-utterance readout
+- bounded mock and HTTP speech-health capability exposure for:
+  - microphone capture shell
+  - streaming preview
+  - manual transcript commit
+- focused automation coverage
+
+## Deferred neighboring families
+
+The first `6R-U` implementation packet must keep these capability families
+closed:
+
+- real device-permission workflow ownership
+- native audio-device route ownership beyond bounded shell state
+- downloadable model or payload shipping
+- provider-profile or BYOK custody
+- voice-output ownership
+- broad assistant-platform scope
+
+Why this slice is next:
+
+- `whisper.cpp` exposes a narrower donor seam at VAD-gated streaming shell
+  posture than at broader model/runtime ownership
+- the already landed `Phase 6R-E` and `Phase 6R-F` packets provide the right
+  local substrate for a bounded shell layer above transcript sessions and
+  orchestration metadata
+- widening directly into permission workflow, model checkout, or payload
+  shipping would blur custody and legal boundaries more than clarify them at
+  this point
+
+## Acceptance criteria
+
+- the packet records why the queue advanced from landed `Phase 6R-T` to
+  `Phase 6R-U`
+- the packet records that the first `6R-U` widening slice is live microphone
+  capture shell profile/state only
+- the packet states exact out-of-scope families for the first `6R-U` pass
+- the packet preserves the upstream `MIT` attribution boundary explicitly
+- the packet leaves permission workflow, payload shipping, and broad
+  assistant-platform ownership deferred
+
+## Validation checklist
+
+1. confirm the landed `Phase 6R-T` packet is the consumed prior queue head
+2. confirm the retained `whisper.cpp` seam narrows cleanly to shell profile and
+   shell-state composition
+3. confirm the next implementation packet is framed as bounded source-backed
+   widening rather than a broad speech-platform transplant
+
+That is the packet.
+
+## Queue effect
+
+This preparation packet is now consumed by the landed bounded `Phase 6R-U`
+implementation slice.
+
+Once that slice lands, the next clean move should stay narrow inside the
+retained `whisper.cpp` row at:
+
+- a source-backed `Phase 6R-V` `ggml-org/whisper.cpp` device-permission and
+  capture-route readiness shell preparation/control pass
