Pause writes, keep lookups

A bad release is proposing wrong replacements at Calder and it must stop shipping now, without stopping customers from getting answers. Pick the stop that blocks effects and not lookups, apply it, and prove both halves live.

Brief
Customer
Calder Equipment (synthetic customer from the Production AI Agents course; every metric and log on this box is made up for the exercise)
Situation
10:15. This morning's release proposes replacements for pumps still under a loaner, and two have reached the operator queue. The product lead says stop everything. Support says customers are mid-conversation and a full stop means silence for them. The runtime has a stop control with three modes.
Your role
You are the FDE who owns the runtime's stop. You have the console and the stop config (bound to the live runtime). The queue holds approved actions from before the bad release.
Goal
Choose the stop that halts new effects and keeps lookups and clarifications running, apply it, prove that the action rate is zero while the gateway still serves, and say what a full stop would have cost.
Objectives
  1. 1.Choose the stop mode (you commit to an answer)
  2. 2.Apply it to the live runtime
  3. 3.Prove both halves: no new actions, gateway still serving
  4. 4.Say what a full stop would have cost (you commit to an answer)
