-- A walk keeps its phases (novox/hq ADR 0282 decision 6, issue 382).
--
-- A small fix took 45 minutes to reach a node on 2026-10-10, and where the time went was read back from the
-- walks by hand: the walk kept when its modules were asked, built, sent first, judged and sent to the rest,
-- but not when its batch's window closed or when it was cut, so the window and the wait behind another walk
-- could not be told apart. A walk now keeps those moments and its class (core or leaf, read at its cut).
-- Its readings, each module's send to the rest and the times of the merges it answers are kept in the plan's
-- own records (modules, delivery). Null for a walk kept before this: its phases before the build are said
-- unknown.
