packet-deepdive

Validate a drafted gate/sprint packet with a four-lane deep-dive: accuracy-vs-repo, cold-read (the overlay's reader persona and access boundary), receipts verification (re-run every count/string/exit-code live), and navigability/structure — with a phase-2 convergence round between accuracy and cold-read, wrapped around the deep-dive-orchestrator subagent, emitting the findings-and-dispositions review doc. Use when the user says "deep-dive the packet", "validate the packet", "packet review", "cold-read the gate packet", or after the packet skill drafts a packet that needs validation before it reaches the reader.
