   survive a broken verb. Rewritten to carry no verb that has to agree: "A CLEAN COPY OF
   YOUR <ITEM> SHIPPED FIRST. THE LEDGER IS SATISFIED." — which also states the mechanic.

+**v9.3 note (landed as I pushed):** `notice.pos?` and `repaired/mirrored by?` are
+RENDER's cues and my lane re-verified clean against them (tsc clean, 277 green). I am
+deliberately **not** surfacing `notice.pos` anywhere in the fax: the round-7 ruling is
+that a notice gives no grid reference, and the field existing for the renderer's
+materialisation cue doesn't change what the paper is allowed to say. `by?` is the first
+thing that could make the FIREWALL LOG per-UNIT rather than per-tile (round 6's honest
+compromise) — happy to take that next round if you want it.
