LCL Studio • Complete Master Architectural Archive

Host: Oracle Cloud Infrastructure (Deployment 12 • https://lcl.onl/12)
Target System: GeneralMobileApp (iOS 17+ / macOS / visionOS)
Scope: 100% of all 13 architectural sections, all 4 proposals, Swift 6 code blueprints, and test protocols.

Section 1: High-Level Executive Summary & Paradigm Shift

An industrial-grade autonomous studio requires eliminating UI thread starvation during high-token-per-second streaming, handling network failover across heterogeneous nodes, and supporting real-time DAG (Directed Acyclic Graph) tool orchestration.

Section 12: Comprehensive Verification & Torture-Test Protocol

  1. Synthetic Token Firehose (100+ tok/s): Stream high-density code output; verify 0 frame drops, ProMotion 120Hz smooth scrolling, and <15% CPU load.
  2. Adaptive Mesh Failover Drill: Sever local MacBook connection mid-stream; confirm session seamlessly downgrades to Oracle 24/7 Hub with 0 message loss.
  3. DAG Rollback Verification: Execute multi-step /plan; test [<< Rollback to Step 1]; verify local workspace and SQLite state revert instantly.
  4. Image / Vision Multi-Modal Ingestion: Upload camera screenshot via PhotosPicker; verify Stealth Ox-Alpha (1M ctx) and Dots-3 ingest and analyze image tokens natively.
