   supersede would silently drop it. A plan whose edges carry a bounded
   cycle (`max_cycles`) or whose nodes carry a retry count opens
   view-only — `ADD workflow`'s `* N` populates `retries`, not
   `max_cycles`, and has no way to re-emit either on a resave, so editing

   A trigger is a standing rule that starts a workflow. The binding points
   trigger → plan and never the reverse — a plan is content-addressed, so one
   that grew a list of triggers would change address every time a trigger was
   added and orphan its own run history. That direction is why a trigger is
   only fully legible NEXT TO the plan it starts, and why these render on the
   canvas instead of on a page of their own: a flat list of four triggers
   cannot show you that two of them start the same plan.

   Read-only, and not by preference. CAL has no `ADD trigger`, and
   `ADD workflow`'s `ON "..."` clause was removed in 1.3, so a console that
   writes only through /api/cal has no way to author one. Firing is withheld
   for the same reason `run.respond` refuses a shared token: it spends budgets
   and executes effects, and the declaring principal IS the audit record. */
