Move to mesh-sdk 16984aa, rebased on its main, which refuses a warrant with no time or for an ask with no expiry

Choosing Silence silenced the condition, the condition was no longer wanted, and the next reconcile
cancelled the Restart or Release ask beside it: an acknowledgement, which any desk click may give,
took an approval back. An open approval ask now stays until it is answered or expires while its
condition is open and silenced with the same answers. The test silences as the controller does; it
failed before (0 open) and passes, and the kept Restart is performed on its warrant.

+// The controller asks, and acts on the operator's warrant (novox/hq ADR 0259 §6). It holds no channel, no
+// identity and no factor: it asks the router like any other module, and performs the answer chosen with its
+// own grant.
+//
+//   - **For every open, unsilenced condition that needs the operator and names its answers**, one ask is
+//     published on the `operator-channel` seat under the controller's own name: the condition's words, its
+//     actions as options at their levels (Silence acknowledges; Release, Stop, Start and Restart approve),
+//     answered by the operator, expiring after a day (a week when every option only acknowledges). A
+//     condition that clears, is silenced, or changes its answers has its ask cancelled; an ask that expired
+//     unanswered is asked again while the condition lasts. Each ask is kept in the controller's bucket
+//     `asked`, so a restart neither asks twice nor forgets.
+//   - **On a warrant**, heard on the seat's event under the controller's own name (which only the router may
+//     say), the controller acts once per ask: only for an ask it holds, only for the option it offered at
+//     that option's level, and only while the condition is still open. It performs the action as itself —
+//     a silence through its own conditions, any other through the verb the action names — with the warrant's
+//     words as its why, and records it in the hand-act log as the operator's decision, naming the channel,
+//     the ask and the proofs. An ask that ended without a choice is recorded and nothing is done.
+//   - **A warrant it missed** while away is read from the router's record of its asks, under its own name.
