+Version 2.0.0. For new general engineering sessions recommend Sol / medium, with high when demonstrated reasoning needs justify it. Preserve the user's selected parent; installation does not switch it. Use Astra for bounded residual hard reasoning, rather than mandatory planning of every task.

 Make delegation useful, observable and bounded. Preserve the selected parent model. The parent owns the critical path, shared decisions, integration and final acceptance. This skill neither changes configuration nor grants external permissions.

 ## Context and ownership discipline
 
+Read [escalation and adjudication](references/escalation.md) when planning exposes uncertainty, a key check fails, shared contracts change or acceptance has unresolved counterexamples. Pause after two same-class failures; preserve issue history across agents. Repair missing inputs first, escalate capability only for reasoning/execution limits, and adjudicate by reproducible evidence rather than model rank. The parent must understand and verify decisive conclusions. Recover to a cheaper adequate route after resolution.
+
 Load only needed references; keep long logs on disk. Avoid whole-history forks and repeating contracts, packets or prior findings. Account for parent context/reasoning, child usage, waiting, retries and integration when evaluating cost.
 
 Production read-only collection is routable by work shape; mutation and final semantic acceptance stay parent-owned. Do not silently relax a project's literal model-owner requirement. Identify the actual rule and resolve it only through authorized changes.
