Attention budget: state and telemetry land, nothing can trigger it

A per-session attention budget with up and down shortcuts is built but completely unreachable.

What probably matters to youSection of the release

Budget levels, telemetry and chat:attentionUp/Down actions exist, but the keybinding and handler maps splice in empty objects.

What

Groundwork for a per-session attention budget, one of "w25", "w50", "w100", "w200" or "unlimited" and defaulting to "unlimited". A cycle handler emits tengu_attention_budget_cycle, a new attachment type carries the budget into and out of the transcript, and two new key actions "chat:attentionUp" and "chat:attentionDown" exist. None of it is reachable: the chat key bindings and handler map both splice in an empty object where those entries would go.

Details
  • The attachment renders nothing and its generator returns an empty list, so the budget never reaches the model.
  • The cycle callback also returns early behind two condition checks that this build does not resolve.
  • A preserveLiveBudget option is passed into session restore and ignored by the function receiving it.
Evidence

tengu_attention_budget_cycle, chat:attentionUp

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
