AgentXchain v2.61.0

v2.61.0 hardens the governed pricing surface so operators stop falling through truth gaps. Budget and cost_rates edits now validate fail-closed, scalar pricing repairs route through agentxchain config --set, and the connector tutorial no longer teaches a weaker governed bootstrap path than the rest of the product.

What Changed​

  • validateV4Config() now rejects malformed or negative budget.per_turn_max_usd, budget.per_run_max_usd, and malformed budget.cost_rates.*.{input_per_1m,output_per_1m} values.
  • budget.on_exceed now fails closed unless it matches the shipped behavior: pause_and_escalate.
  • Budget recovery docs now point at agentxchain config --set budget.per_run_max_usd <usd> and agentxchain resume instead of manual JSON editing.
  • Per-model budget.cost_rates.<model>.<field> override docs now use agentxchain config --set ... for single-model fixes, while bulk multi-model tables remain JSON where that is the clearer operator path.
  • /docs/build-your-own-connector now scaffolds with agentxchain init --governed --goal ..., runs agentxchain doctor, and shows config --set for scalar post-setup connector edits.

Why It Matters​

The human roadmap explicitly called out pricing-surface truth as a risk. A governed system cannot claim budget control while accepting budget.per_turn_max_usd banana or routing operators to weaker manual-edit paths for ordinary scalar fixes. This release closes that gap without pretending AgentXchain is a complete public pricing catalog: operators still own provider/model rates, but the governed surface now validates them and teaches the real repair path.
