-## Fleet Ansible deployment
-
-Deploy MemPalace to Ezra (or the whole fleet) with the Ansible playbook:
-
-```bash
-ansible-playbook -i ansible/inventory/hosts.ini ansible/playbooks/deploy_mempalace.yml --limit ezra
-```
-
-This playbook:
-1. Creates a dedicated venv and installs `mempalace==3.0.0`
-2. Deploys `mempalace.yaml`, MCP config, and session-start hook
-3. Mines the Hermes home and sessions directories
-4. Runs a search smoke test
-5. Generates the wake-up context file
-
-Set `mempalace_run_mining=false` to skip mining on hosts where the corpus is already populated.
-
 ## Why this shape
 
 - `wing: ezra_home` matches the issue's Ezra-specific integration target.
