  "message.content": "# Executive Summary\n\nThis engineering dossier outlines a comprehensive deployment-grade plan for a private home-lab FastAPI service that proxies OpenAI-compatible requests to a local llama.cpp server. The system supports benchmarking, artifact storage, reasoning measurement, and privacy compliance while addressing critical pain points identified in the current setup.\n\nThe core objective is to transform the current ad-hoc benchmarking and proxy infrastructure into a robust, auditable, and scalable system that can handle large-scale outputs, maintain privacy, and provide actionable insights for model performance comparisons. This involves enhancing data models, implementing artifact storage, designing reasoning budget tracking, and creating comprehensive reporting capabilities.\n\nKey improvements include:\n- Durable artifact storage for long benchmark outputs\n- Measurable reasoning budget tracking without disabling thinking\n- Comprehensive benchmark metadata for model comparisons\n- Privacy-preserving redaction of sensitive content\n- Auditable model profile changes\n- Scalable handling of large token outputs\n\nThe deployment plan includes detailed migration strategies, test coverage, and rollback procedures to ensure minimal risk during deployment.\n\n# Current Architecture\n\nThe current system consists of:\n\n1. **FastAPI App (app/main.py)**:\n   - Exposes dashboard endpoints\n   - Health check route\n   - OpenAI-compatible proxy at /v1/chat/completions\n\n2. **Proxy Layer (app/proxy.py)**:\n   - Forwards requests to llama.cpp server at 192.168.1.116\n   - Records request metadata, response previews, timings, and usage\n   - Stores data in SQLite database\n\n3. **Data Persistence (app/store.py)**:\n   - Write helpers for runs, client sessions, llm_requests, events, and benchmark rows\n\n4. **Reporting (app/reports.py)**:\n   - Aggregates dashboard and report metrics from SQLite\n\n5. **Benchmarking (app/bench.py)**:\n   - Runs benchmark campaigns against the proxy\n\n6. **Deployment (deploy/docker-compose.yml)**:\n   - Runs ai-flight-recorder beside llama-cpp-server\n   - Data stored on /models/flight-recorder/data\n\n7. **Model Profile**:\n   - Qwen3.6-35B-A3B-APEX-MTP-I-Balanced.gguf\n   - llama.cpp reasoning enabled\n\n# Failure Modes Found\n\n1. **Long Output Handling**:\n   - Inline JSON responses become unwieldy for large outputs\n   - UI rendering struggles with large previews\n   - Storage limitations for response previews\n\n2. **Reasoning Budget Measurement**:\n   - No way to track reasoning tokens separately from generation tokens\n   - Cannot measure reasoning without disabling thinking\n\n3. **Benchmark Metadata**:\n   - Insufficient metadata for screenshots and comparisons\n   - No durable artifact storage for benchmark results\n\n4. **Privacy Leaks**:\n   - Risk of leaking private email or Teams content\n   - No redaction mechanism for sensitive data\n\n5. **Model Profile Changes**:\n   - No audit trail for model profile changes\n   - No versioning of model configurations\n\n6. **Timeout and Storage Stress**:\n   - Long-running tasks exceed timeouts\n   - Storage limitations for large outputs\n   - UI rendering issues with large previews\n\n# Data Model Changes\n\n## Enhanced SQLite Schema\n\n```sql\n-- Enhanced runs table\nCREATE TABLE runs (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    name TEXT NOT NULL,\n    description TEXT,\n    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    started_at TIMESTAMP,\n    completed_at TIMESTAMP,\n    status TEXT DEFAULT 'pending',\n    model_profile TEXT,\n    benchmark_config TEXT,\n    metadata JSON,\n    artifacts_path TEXT,\n    total_tokens INTEGER,\n    total_cost REAL,\n    duration_seconds REAL\n);\n\n-- Enhanced llm_requests table\nCREATE TABLE llm_requests (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    run_id INTEGER,\n    request_id TEXT UNIQUE,\n    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    request_json TEXT,\n    response_json TEXT,\n    response_preview TEXT,\n    response_tokens INTEGER,\n    prompt_tokens INTEGER,\n    reasoning_tokens INTEGER,\n    total_tokens INTEGER,\n    duration_ms INTEGER,\n    status TEXT,\n    error_message TEXT,\n    model_profile TEXT,\n    prompt_hash TEXT,\n    FOREIGN KEY (run_id) REFERENCES runs (id)\n);\n\n-- Enhanced benchmark_results table\nCREATE TABLE benchmark_results (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    run_id INTEGER,\n    task_name TEXT,\n    task_description TEXT,\n    input_prompt TEXT,\n    expected_output TEXT,\n    actual_output TEXT,\n    metrics JSON,\n    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    FOREIGN KEY (run_id) REFERENCES runs (id)\n);\n\n-- Enhanced model_profiles table\nCREATE TABLE model_profiles (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    name TEXT UNIQUE NOT NULL,\n    description TEXT,\n    file_path TEXT,\n    file_hash TEXT,\n    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    is_active BOOLEAN DEFAULT FALSE,\n    config JSON,\n    audit_log TEXT\n);\n\n-- Enhanced artifact_storage table\nCREATE TABLE artifact_storage (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    run_id INTEGER,\n    artifact_type TEXT,\n    filename TEXT,\n    file_path TEXT,\n    size_bytes INTEGER,\n    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    metadata JSON,\n    FOREIGN KEY (run_id) REFERENCES runs (id)\n);\n\n-- Enhanced privacy_redactions table\nCREATE TABLE privacy_redactions (\n    id INTEGER PRIMARY KEY AUTOINCREMENT,\n    run_id INTEGER,\n    redaction_type TEXT,\n    content_hash TEXT,\n    redacted_content TEXT,\n    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,\n    FOREIGN KEY (run_id) REFERENCES runs (id)\n);\n```\n\n## Migration Strategy\n\n1. **Schema Migration**:\n   -
