docs/OPERATIONS.md does not exist in this repo; docs/RUNBOOK.md remains the single canonical operational surface for pass-1 rollout.
Additional integration and surface docs stay repo-local and are classified through docs/docs.manifest.yaml.
The Jadda interface bounded stack deployment lane is documented in JADDA_INTERFACE_HOST172_STACK_MATERIALIZATION.md (docs/JADDA_INTERFACE_HOST172_STACK_MATERIALIZATION.md).
