Rail-independence is the plan's spine: fedlearn rails verified NOT landed
(no m2/m2-core, no capture/curator CLIs), so the wedge builds against frozen
interfaces — m2/market-registry as registry of record, ApplyAdapter seam with
local adapter now / m2core-sync stub, schemas frozen here with a fedlearn
coordination note. Constitution check passed (1 justified deviation).
