Groundwork for sparing some agents from a stop cascade

Not switched on
Useful2 Signal4
Subagents

Stopping one agent still stops them all, though the code to spare some is now present.

Each agent is tested against an exemption rule list before being killed, but nothing ever adds a rule, so none are spared.

What

Stopping an agent still stops every other running agent with it. New in this build is the machinery to exempt some of them: each other agent is tested against a list of exemption rules and, if exempt, added to a "spared" list instead of being killed. Nothing in this build ever adds a rule to that list, so no agent is ever spared and stops cascade exactly as before.

Details
  • The exemption list lives on the shared registry of running agent tasks; the bundle contains its declaration and one place that reads it, and nothing that writes to it.
  • The spared list is announced through a cascadeSpared event that nothing in the build listens for.
  • There is no flag or setting; the feature is inert because the rule list is empty.
