Summary

fix: address #1180, #1181

What was solved

#1180 — Implement debug mode with verbose output

Add a debug mode with configurable verbosity levels, verbose operation logging, debug breakpoints, debug utilities, an interactive debug console, and debug analytics. The issue is broad and touches cross-cutting SDK concerns; a focused implementation should introduce a small debug module (levels, logger, breakpoints, utilities, console, analytics) and wire it into the existing SDK surface without refactoring unrelated code.

Addressed:

• Changed: src/analyticsTracking.ts, src/tests/sdkFeatures.test.ts
• Design and implement debug levels (e.g., off/error/warn/info/debug/trace) with a configurable threshold
• Implement verbose logging that emits detailed operation logs gated by the active debug level
• Add debug breakpoints that can pause/flag execution at named points when debug mode is enabled

#1181 — Add profiling tools for performance analysis

Add a profiling toolkit to the SDK covering CPU profiling, memory profiling, flame graph generation, call tracing, profile export, and a profile viewer. The repo already has an examples/profile-session.ts hinting at a profiling surface, so the contribution should introduce a focused profiling module (likely under src/) plus a viewer/export helper, keeping scope to profiling only and not touching unrelated SDK features.

Addressed:

• Changed: src/profileViewer.ts
• Implement CPU profiling (sampling of hot code paths)
• Add memory profiling (heap/usage tracking)
• Create flame graphs from collected samples

Changes

• src/analyticsTracking.ts (modify)
• src/__tests__/sdkFeatures.test.ts (modify)
• src/profileViewer.ts (create)
