row 269 (264b, #1774): refusedOnce in sessions.test.mjs pins actor_run, closing Duckworth N1 (DEFERRED.md:474-480)

Allowed by Mos in mos-1292 (copy mos-1294) on mos-1285's terms. The SELECT
reads actor_run, the expected row gets the run-name literal, and the three
callers pass `${name}-run`. Nothing else in the test changes. The old
expected row was:

  [['action.refused', { code: 'not-holder' }]]

DEFERRED.md gets a closing line on the entry naming row 269.
