+# Advanced Code Review
+
+Your task is to find all potential bugs and code improvements in the code
+changes. Focus on:
+
+1. Logic errors and incorrect behavior
+2. Edge cases that aren't handled
+3. Null/undefined reference issues
+4. Race conditions or concurrency issues
+5. Security vulnerabilities
+6. Improper resource management or resource leaks
+7. API contract violations
+8. Incorrect caching behavior, including cache staleness issues, cache
+   key-related bugs, incorrect cache invalidation, and ineffective caching
+9. Violations of existing code patterns or conventions
+10. Duplicate code
+
+Make sure to:
+
+1. If you find any pre-existing bugs in the code, you should also report those
+   since it's important for us maintain general code quality for the user.
+2. Do NOT report issues that are speculative or low-confidence. All your
+   conclusions should be based on a complete understanding of the codebase.
+3. Remember that if you were given a specific git commit, it may not be checked
+   out and local code states may be different.
+
+## Scope
+
+All code across the ByteLyst workspace repos:
+
+- **learning_ai_common_plat** - Shared platform packages and services
+  - packages/ - @bytelyst/\* shared libraries
+  - services/ - platform-service, extraction-service
+  - dashboards/ - admin-web, tracker-web
+- **Product repos** - Individual product backends and applications
+  - learning_voice_ai_agent (LysnrAI)
+  - learning_multimodal_memory_agents (MindLyst)
+  - learning_ai_clock (ChronoMind)
+  - learning_ai_fastgap (NomGap)
+  - learning_ai_flowmonk (FlowMonk)
+  - learning_ai_jarvis_jr (JarvisJr)
+  - learning_ai_peakpulse (PeakPulse)
+  - learning_ai_notes (NoteLett)
+
+## Domain Context
+
+This is a multi-product ecosystem with shared platform services. Key architectural patterns:
+
+- **Platform services** (Fastify 5, TypeScript ESM) provide auth, telemetry, feature flags, etc.
+- **Shared packages** (@bytelyst/\*) eliminate duplication across products
+- **Product backends** handle domain-specific logic (port 4010-4017)
+- **Web apps** use Next.js 16 + React 19
+- **Mobile apps** use native platforms (SwiftUI, Jetpack Compose, React Native)
+
+## Style
+
+Make sure the code follows existing conventions:
+
+- TypeScript: ESM, strict types, Zod validation
+- Services: Fastify 5 with types.ts → repository.ts → routes.ts pattern
+- Cosmos DB: All documents include productId field
+- No console.log in production (use req.log/app.log in Fastify, structlog in Python)
+- Commit messages: type(scope): description
+- Colors: Use design tokens from @bytelyst/design-tokens, never hardcode
+
+## Target Branch
+
+Measure against the main branch of the respective repo since that will be the branch we will merge into.
+
+## Comments
+
+Do not make code changes directly. Instead, suggest changes so the reviewer can evaluate them manually.
+
+## Grammar
+
+Do not include em dash in any outputs.
+
+## Summary
+
+At the end, provide a numbered list of all potential issues found. Each issue should have a number so it can be referred to easily (e.g. "3").
+
+Also include a summary and explanation of the change of the PR or diff in general from the target branch. Use mermaid diagrams, anecdotes, and any other format you see fit.

+description: Run a network transfer audit for a time window and generate an interactive HTML report
+---
+
+# Network Transfer Audit Workflow
+
+The primary interface for running audits is the **Sensor Audit Dashboard**.
+
+## Steps
+
+1. **Ensure the dashboard is running**
+
+```bash
+/Users/sd9235/code/mygh/learning_ai_mac_tooling/audit-ctl.sh start
+```
+
+2. **Open the dashboard**
+
+```bash
+/Users/sd9235/code/mygh/learning_ai_mac_tooling/audit-ctl.sh open
+```
+
+Navigate to **Run Audit** in the sidebar.
+
+3. **Choose a mode in the dashboard UI**:
+   - **One-shot Audit** — Analyze past network activity for a time window
+   - **Monitor** — Actively monitor transfers for a duration, then report
+   - **Continuous Collection** — Long-running data collection into SQLite
+
+4. **Click Start Audit** — Output streams in real-time. When done, click **Open Report** to view the HTML report.
+
+5. **View reports** — Go to the **Reports** page in the sidebar to see all generated HTML reports.
+
+6. **Browse sessions** — Go to **Sessions** to explore collected data and sensor samples. Click **Generate Report** on any session to create an HTML report from it.
+
+## CLI Fallback
+
+For headless or SSH scenarios, the CLI still works:
+
+```
+python3 tools/network_transfer_audit.py [TIME] [OPTIONS]
+
+Time (pick one, required):
+  --last DURATION          Relative: 30m, 2h, 1d, 7d
+  --from DATETIME          Absolute start: "YYYY-MM-DD" or "YYYY-MM-DD HH:MM"
+
+Options:
+  --to DATETIME            End time (default: now)
+  --live                   Include live connection snapshot
+  --monitor DURATION       Monitor transfers for DURATION (5m, 10m, 1h) before report
+  --json                   Output as JSON
+  --html FILE              Generate interactive HTML report
+
+Continuous Collection:
+  --collect DURATION       Collect data for DURATION (e.g. 12h, 1d) into SQLite
+  --interval SECONDS       Collection interval (default: 300 = 5 min)
+
+Query Collected Data:
+  --data SESSION_ID        Query collected data from a session
+  --sessions               List all collected sessions
+```
+
+## Management Script
+
+```bash
+./audit-ctl.sh start          # Start dashboard (API + UI on port 8742)
+./audit-ctl.sh stop           # Stop dashboard
+./audit-ctl.sh status         # Check health + stats
+./audit-ctl.sh collect 12h    # CLI collection shortcut
+./audit-ctl.sh install        # Auto-start on login via launchd
+./audit-ctl.sh open           # Open dashboard in browser
+```
