From 1415037ac4d20f83a54075521c306966810bf97e Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 15 Mar 2026 13:15:52 +0000 Subject: [PATCH 01/36] feat: integrate patchright and discovery rate limiting for cloudflare bypass Replaced Playwright with Patchright (a stealthy drop-in replacement) to prevent Cloudflare from detecting headless mode. Implemented randomized delays (jitter) between API requests in LibraryDiscovery to mimic human-like pacing. Removed redundant manual automation-hiding flags as Patchright handles stealth internally.

Replaced Playwright with Patchright for deep browser stealth. - Implemented a dual-layer Strategy Pattern for discovery and extraction. - Added 4 distinct strategies per phase: API, Scroll, Interaction/Native, and AI-Assisted. - Native Export strategy now mimics human interaction (Thread -> Settings -> Export). - AI Scrape strategy uses local Ollama models for dynamic selector extraction. - Added a Cloudflare handler that automatically bypasses challenges and triggers strategy fallback. - Updated .env.example and README.md with comprehensive stealth documentation. - Verified with mock-based integration tests.
