+Merged and completed.
+
+Implementation:
+- Added resource-backed Pod orchestration guidance at `resources/prompts/common/pod-orchestration.md`.
+- Registered the guidance through the prompt catalog and internal prompt resources.
+- Added conditional system prompt assembly based on registered Pod-management tool names.
+- Guidance is included for Workers with Pod management tools and omitted otherwise.
+- Guidance explicitly says Pod notifications are background signals handled at natural stopping points, that the parent does not need to keep a turn open solely to wait, and that agents should not use `sleep`/polling loops just to wait for Pod output.
+- Guidance also preserves evidence-before-completion and no scheduler/authorization-bypass constraints.
+
+Review:
+- External reviewer approved with no blockers.
+
+Validation after merge:
+- `cargo test -p pod pod_orchestration` passed.
+- `cargo test -p pod prompt::catalog` passed.
+- `cargo fmt --check` passed.
+- `./tickets.sh doctor` passed.
