What this mode does
Runs the scrum master pipeline: walks target source files, compares each to the PRD via cloud LLMs (Grok 4.1 / DeepSeek V4 / Qwen3-235B with same-model retry), observer hand-reviews each candidate, applier lands surgical patches that pass cargo-green + warning-stable + rationale-aligned gates. Designed for finding code drift against the PRD and committing only verified fixes.
