 `make lint-fast` and `make lint` run the same guard through `scripts/check_repo_hygiene.sh`, so runtime deprecations fail before longer suites.
+The guard covers action runtime majors, not the application Node version configured in a workflow, so docs/UI jobs may keep `node-version: "22"` while still requiring `actions/setup-node@v5+`.
 Do not rely on `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true` or `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true` as the default fix path; keep those as emergency-only compatibility levers while the action pin is being updated.

 This path writes `.gait.yaml`, reports the live policy contract, and returns install-safe next commands.
 
+It still does not enforce inline unless you wire Gait into a real wrapper, sidecar, middleware, or MCP boundary before the tool call executes.
+
 ### Integrate At The Runtime Boundary
 
 Use this when your agent already makes real tool calls and you want enforcement at the execution seam.
 
+This is the first path that enables strict inline fail-closed enforcement. If you cannot intercept tool execution before side effects, stay on the proof, observe, capture, and regress paths instead of claiming runtime blocking.
