+
+Re-pin, on Mos's go (decision 109). Copy
+`621a2599ba18ba2b41df0793eb20e544d1fc97bd` was built from the landed
+commit, and rollback set `/mnt/storage/scratch/sage-pin-rollback-fed66feff`
+was saved first. Mos ran the idle check at 17:44:50Z and stopped webui,
+then bus, at 17:45:09Z. At 17:46:32Z I ran `bus-service.sh install --copy`
+(`--pm --claude ~/.local/bin/claude`), `webui-service.sh install --copy`
+with the unit's existing flags, and `stack-copy.sh wrapper`. The diffs
+against the rollback set changed only the copy id, in both units and in
+the wrapper. `stack-copy.sh check` returned 0. Environment and drop-ins
+were unchanged. Mos started bus at 17:46:49Z and webui at 17:46:52Z.
+Downtime was 17:45:09Z to 17:46:52Z. ps at 17:47:14Z showed 5 stack
+processes, all from copies/621a2599b: bus CLI, bus process, Console, and
+PM run rf2734867932b's bwrap and runner. Nothing still ran from
+fed66feff. Row 117 isn't proven until a coder launch logs
+`checkout-fetched` or the clean path. Mos is watching for it. Before the
+stop, Jason's Console one-off at 17:21:52Z had already put the coder's
+clone back on refactor, clean at 0c3826910, keeping work/prd-v1-1 at
+8ae5a149.
+
+Row 116 brief round 2 (68ce7f354, queue rev 1148, uncommitted). Darkwing
+found that round 1's read path, "the Console's and `mosaic`'s", is
+human-only (#225). The conductor runs in an agent seat and can't use
+it. Ruling: `land-work` opens bus.sqlite `readOnly: true`, runs SELECTs
+only, and refuses `bus-schema` on a schema digest mismatch. There's no
+broker change. I read the live rows for f71c73c9 and tasks 19/265 and
+19/229 read-only, into `agents/sage/work/row116/live-rows.json`. The
+decision's `task_ref` is null. The raise's `action.allowed` holds
+`target: "refactor"` and `approvalChoice: "yes"`. The brief now says
+where each check reads its fact.
+
+Q145 follow-up for Mos (sage-0194), read-only, no design:
+- A role session takes one turn per message, serially, in seq order.
+  Sender gets no priority (runner.mjs:345-399, broker.mjs:994). A human
+  message waits behind queued agent messages.
+- Each instance has one holder (REQ-ROLE-2, broker.mjs:717).
+- A COS-owned standing launch policy is option 2 under another name,
+  with agent-written authority.
+- My call: option 2's shape plus a human-first intake lane. That caps
+  Jason's wait at the one turn in flight, not zero.
