row 271 (264d, #1776): clear context build round 1, not run (slot held). Broker: session.clear, session.cancel and session.operation, the fence on send/open/claim, cancel at arrival for routed messages, the drained receive and the end drain, trusted ops sessionClears and sessionClearExited/Uncertain/Retire/Start. Launcher: clearPass before the threads loop (stop, proof, retire, successor start through check()/start()), waiting on a live row 269 survivor. Old tests per mos-1315, rebased on row 206 (sage-2968): label 3m to 3n, future step 3n to 3o, 3m-3n.sql in the engine copies and file lists, ready lines, later3l and the rows() exclusions gain both tables as 206 did for thread_shares (mos-1292, approved in mos-1336), schema.test counts 25 tables and 96 triggers, COUNTED and T45 LISTED gain both tables after thread_shares (mos-1318, mos-1319), TESTER_VERBS pin (mos-1325), fixtures/schema-3m.sql
