Rows by role replace the pins as the live source (frontmatter stays as the
off-state floor): phases write=work/high and apply=work/low, 56 skill rows,
21 agent rows + Explore/Plan. Agents get the row's model at spawn (within
the tier, upward only, explicit params win, project-defined agents skipped
via agent.offer) and its effort per step. A typed slash of a rowed skill
routes main through a name-bound marker (composer|sdk|bridge, pending slot
mid-turn) or the idle fallback; a best-tier row lives in a runMain slot
that survives turn end and route calls. An unrowed skill leaves the route.
Typed /effort-* floor code removed (bridge kept until W2-B). The route
answer always names the id. Override rows accept null. Kit suite 58 → 88.
