nx_role_store_migrate.nx -- MIGRATE the knowledge/roles/*.tsv files into the SOVEREIGN seg-store (knowledge/store/roles-*, via nx_role_store). Operator 2026-06-22: "migrate and get rid of these tsvs just nishi ecosystem." Reads each legacy .tsv, seeds its rows into the matching channel in ONE batched commit (1 segment), then reads EVERY row back and byte-compares to the source line -> GREEN only if every source row is present byte-exact. IDEMPOTENT (rule#10): a channel is seeded only when EMPTY (count==0); once seeded (and possibly evolved by live appends) a re-run writes nothing and still verifies. ADDITIVE (rule#13): the .tsv files are not touched here -- retirement to knowledge/_retired_tsv/ is a separate, post-verify step. pm_coord.tsv -> pmcoord engineer_queue.tsv -> engineerq doctor_queue.tsv -> doctorq engineer_ledger.tsv -> engineerl expect_exit: 0 license_tier: ORIGINAL
