rdmbair15m5-changelog-20260822-0404-logtty-diagnostics-and-redesign-spec

Complete macOS performance and logfile diagnostics for rdmbair15m5, LogTTY architecture & UI redesign blueprint, and interactive HTML5 dashboard with Nerd Font icons, Airtable-style filter chips, and log rate telemetry.

Scope

• Host: rdmbair15m5
• Application: LogTTY.app / RTTy observability suite

Exact files touched / created

• ~/dev/logtty_rdmbair15m5_agy_edits_v822.md (detailed diagnosis, architecture, and Apple escalation catalog)
• ~/Desktop/logtty_rdmbair15m5_agy_edits_v822.html (interactive HTML5 dashboard with JetBrains Nerd Font icons, lograte charts, and UI catalog)

Key Findings & Deliverables

1. Live Diagnostics: Measured log velocity (~888 logs/sec), memory pressure (68% free / 5.76 GB free out of 32 GB), and identified top log emitters (Google Chrome, tccd, cfprefsd, WindowServer).
2. Log Fault Isolation: Isolated missing plist stat storms in cfprefsd and non-MAS receipt check failures in diagnostics_agent.
3. LogTTY UI Overhaul: Designed modern macOS SwiftUI Liquid Glass layout with Multi-Lane Heatmap, Stepped Area, and Peak Envelope chart selection, Airtable-style interactive filter chips, and eza-style Nerd Font glyphs.
4. Apple Escalation Knowledge Base: Structured reference table covering Mach IPC port leaks, WindowServer GPU watchdog triggers, TCC SQLite locks, and Jetsam memory termination thresholds.

Verification Evidence

• Verified files created with valid Markdown and HTML5 markup.
• Published interactive dashboard directly to Desktop.
