Development record

Open specs with two or more steps declare no step's needs, so every build run of them is fully serial by default (ruling DR6b: a step with no needs line waits for every earlier step). On origin/main on 2026-10-23 only 5 of 169 specs declared any needs line. The open specs most affected are the merge gate's and the model matrix's, which are being built now. No one is adding needs lines to the open specs yet.
