TODO.md: the Fred section moves from "RESUME HERE" to shipped, with the gate numbers,
the six-cuts-five-discarded history, and the audition-first list of 6 kitcheck
advisories that are now waiting on PLN's ears rather than on any tool.

completed-archive.md: #21 (La Cale) and #20b (the pack) as standalone entries. The
learnings worth carrying: the rack had to BE `loopAt` rather than resemble it; a gate
blocks on defects and reports properties, because blocking on a property is a gate
everybody learns to ignore; `n` is the folder's index, never the manifest's; a rounded
tempo is a stretched loop; and three tests that passed while proving nothing, which was
most of the day's actual value.
