Development record

An intent build re-widens its reservation to the spec's whole footprint at every step, instead of reserving only the packages of the lanes it has open. A spec footprint that names whole packages (or the whole of commands/) then overlaps peers' narrow file reservations, so the build's renewal at land is refused until the peer releases by hand, and a hand-narrowed reservation is widened again at the next step. Seen 26-28 Oct on run-2610252354599453: a peer's commands/land.md and commands/guard.md reservations blocked lane 1's renewal.
