Records what each bucket means and which fix it points at, the four rules that
keep the classification honest (same-message calls, bookkeeping tools, subagent
threads, earlier-explore files), and the three real transcripts it was
hand-checked against -- including the excalidraw canvasNonce run, where it
independently found the data-flow frontier CLAUDE.md already documents: 0%
sufficient, without being told what to look for.
Also states what it does NOT say: sufficient is not correct, one Read is a vote
rather than a proof, and bucket 1 is ambiguous by construction.
