Dec 1, 2025December 2025: Delivered feature-focused performance improvements and stability fixes for facebook/sapling. Key changes include: 1) Recommended bookmarks overhaul: removed feature flag, moved to Ent-based server-side mapping for bookmark names, and cleaned up dead v1 code, reducing startup latency and simplifying the UI. 2) Startup fetch optimization for smartlog commits: started fetching when the repo is set with caching, improving startup time and reducing on-subscribe work. 3) ISL signals stability and TypeScript fixes: fixed failing signals, addressed TS errors, and improved the MergeConflicts test to ensure reliability. Business impact: faster startup, fewer flaky signals, improved reliability for bookmark onboarding, and lower maintenance burden. Technologies demonstrated: Ent-based mapping, GraphQL integration with isl-server, TypeScript fixes, prettier/CI hygiene, performance optimization, and test reliability.
