VALIDATION REPORT — LP SCR 3.2.4.4 DISTRIBUTED FAST DEMO BUILDER v1.3.0.6.4.6
Generated UTC: 2026-08-03T18:48:55.099284+00:00

RELEASE IDENTITY
- Core/runtime: Smart Conference Room 3.2.4.4
- Builder: 1.3.0.6.4.6
- CR Engine semantic version retained: 0.2.14.1
- Scope: CUDA/Vulkan/Metal/Core ML runtime verification, batched/persistent inference, resumable model download and Windows-safe atomic state handling.

IMPLEMENTED SCOPE
- CTranslate2 CUDA probe uses the configured CR Python environment.
- Faster-Whisper CUDA path uses BatchedInferencePipeline; configured batch size is effective and reduces 8 -> 4 -> 2 -> 1 only for memory errors.
- CUDA CPU thread default is bounded; requested, resolved and verified backend metadata are separated.
- Whisper.cpp processes all physical segments in one invocation per job to avoid model/runtime reload for every segment.
- Vulkan, Metal and Core ML runtime evidence is parsed strictly; explicit disabled backend signals cannot be reported as verified.
- Metal-only is distinguished from Core ML encoder + Metal decoder.
- Whisper.cpp/Core ML model downloads use revision-locked artifacts, exact size/hash verification, HTTP Range resume and unique atomic state files with Windows retry.
- UI reports preflight backend separately from actual backend self-test/job evidence.
- Resume-from-step-11 invalidates/regenerates CR bytecode and rebuilds affected CR/PC assets.
- No change to CR compare/alignment/hallucination rules, transcript semantics, meeting lifecycle, DICENTIS, Voting, Android STT or database schema.

VALIDATION PASS
- SCR 3.2.4.4 accelerator runtime policy tests.
- Resumable downloader/atomic-state synthetic tests.
- Faster-Whisper CUDA batch contract tests.
- Whisper.cpp single-process Vulkan/Metal/Core ML evidence tests.
- Full CR 0.2.14.1 regression chain through transcript-start placement.
- Runtime/core version consistency.
- Builder/core version contract.
- Pro and Ultimate distributed package fixtures + verifier.
- CR runtime-root/worker/relocation/Pyannote waveform contract.
- Protected public assets/Owner License/Launcher resume contract.
- PowerShell/CMD encoding and architecture static checks: 20/20 PASS.

ENVIRONMENT-LIMITED / NOT EXECUTED HERE
- Native Windows PowerShell 5.1 SEA build and real EXE launch.
- Physical NVIDIA CUDA, AMD/Intel Vulkan, Apple Metal and Apple Core ML acceptance.
- Live public model download; downloader was validated with deterministic local HTTP fixtures including resume/failure paths.
- Android release signing and Bosch DICENTIS hardware acceptance.
- Dependency-bound Central E2E requiring unavailable npm dependency xlsx.

RESULT
SOURCE / STATIC / TARGETED / SYNTHETIC / PACKAGE-FIXTURE: PASS
NATIVE WINDOWS / PHYSICAL ACCELERATOR ACCEPTANCE: PENDING
