Short reopen cycle -- resolved a 6-item backlog from Builder[20] and Tech[30] sessions, ran JANUS as a check-in, resolved 2 more items that landed (Tech close report, a test message). No new substantive Master work this cycle. Tech confirmed EXEC_OPEN Series T works cleanly with no self-forcing needed.

Reopened, resolved pickup (6+2 items across both queues), ran JANUS check-in (correctly blocked from overwriting the deeper post-close handoff by shrink-guard), appended a REOPEN CYCLE ADDENDUM to handoff-10.md.
