~x-ai/grok-latest → A (3:1)

A adds reusable offline compile/scan APIs (offline.rs ~300 LOC with ranking simulation, JSONL replay, and unit tests) plus a documented workspace binary that permanently improves DSL/CI workflows. B only repairs test doubles (regex split, getRequestBody, nil-safe state encode, try/catch) and a couple of Playwright helpers so E2E auth runs again—valuable but narrower and test-only.
