Depends on langchain-ai#4870 Hooks v2 can now match configured lifecycle handlers, execute command hooks safely, and return typed event-specific decisions. --- The engine captures immutable configuration snapshots, projects all nine events onto the compatible wire protocol, bounds subprocess time and output, and reduces ordered results without changing the legacy dispatcher. Lifecycle call-site integration remains in a later stack layer. <details> <summary>Test plan</summary> - 99 focused hook/model compatibility tests - `make lint` - `make check_imports` </details> Made by [Open SWE](https://openswe.vercel.app/agents/019f81f5-89a5-703a-a090-0160871a1091) ## References - Plan: https://openswe.vercel.app/agents/019f81f5-89a5-703a-a090-0160871a1091/plan --------- Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

Depends on #4870
Hooks v2 can now match configured lifecycle handlers, execute command hooks safely, and return typed event-specific decisions.
The engine captures immutable configuration snapshots, projects all nine events onto the compatible wire protocol, bounds subprocess time and output, and reduces ordered results without changing the legacy dispatcher. Lifecycle call-site integration remains in a later stack layer.
