steps callers: the runner, the indexer, the operator and sessions (D-18); BLD12 builds in the fetch;
BLD13 resolved and the toolchain digest; BLD14 the step key <asker>.<node>.<id> beside main's
<node>.<id>; the events toolchain-reported and step-progress on the three build seats, and
step-progress on mesh-wants.
Builds: design 47 G §463, §480, §465, §466, §467, §481, §483, §492, §496

A kind's subject is <stream>.<kind>: check.step, delivery.step (a recovery's steps, the
runner alone) and check.run (node-build-go). Regenerated with seatgen at mesh-catalog
b5aebbbe (GEN4); its fixture rows for the three subjects fail to compile against the
contract before.
Builds: design 47 G §415, §455, §22, §206, §86, §338.

Builds: design 47 G §22, §338 (accepted kinds step, runner alone; run, node-build-go,
callers the runner, the indexer, the assigner and the checker), §326, §414 (state
detected-steps, one key per artifact, apart from today's step keys steps).
Not built: §415's kind names check.step, check.run, delivery.step (the definition
reader refuses a dotted accepted-kind name); stopped on that question.

Builds: design 47 G §22, §116, §206, §271, §326, §338 (callers: steps the runner
and the indexer, drop the runner and the builder, kept-artifact the node-engines),
§24, §331 (step-ended.<node>, 128 MiB), §370, §373 (the ask carries the version and
each package member's digest), §203, §324 (acts build on the language).
Not yet in this commit, left as the dev branch built them and not read against the
lines: the accepted kind names (dev's 'step'; G-9 §415 names check.step, check.run,
delivery.step), the state rename detected-steps (G-9 §414).
