grok-repo

Read purpose, structure, mechanics, then history for the why; judge taste only after evidence. Pick one mode by the question; every claim cites a file path or commit:

• Scoped question ("how does X work?", "where does Y come from?") → a dataflow trace.
• Change question ("why was X added?", "how did this feature evolve?") → change archaeology.
• Whole-repo question ("explain this codebase", "give me a tour") → the full briefing.

Dataflow trace (scoped mode)

Follow one datum — request, message, config value, file — from entry to effect. The trace is the answer.
