+### ASCII has no exemptions, generated output included
+
+The ASCII-only policy is strict: every tracked file, with nothing carved out -- not `generated/`, not
+`verification/`, not the `HELP.md` files, not a license text. An em-dash is never acceptable anywhere, and that
+includes the agent's own replies. When a tool writes a non-ASCII character into its output, fix it at the source:
+post-process the output in the task or `et-int-gen` step that runs the tool, as `gen:python-rest` does for
+openapi-python-client's docstrings and `et-int-gen`'s HELP.md rendering does for clap-markdown's separators.
+Hand-maintained files that happen to live in a generated tree are just source, and get fixed by hand.
+
+Never reach for an exemption instead. The `no-non-ascii` rules carry no path scoping, and the `no_exemptions` policy
+fails the build if one is added; a suppression comment naming either rule, or naming no rule and so silencing all of
+them, is flagged by `no-suppressing-unexemptable-rules`. Those two hold every rule on the policy's `unexemptable`
+list the same way, so a rule that must apply to every file without exception goes on that list. Taking a rule off
+it is a policy change and needs the operator's explicit sign-off, exactly as deleting a lint rule does.

 - `WS_MESSAGE_RETENTION=all` makes the hub keep every unacknowledged direct message a recipient has from a sender,
   rather than only the newest. The default, `latest-per-sender`, behaves as before.
+- An operator can block an IP address, or evict a misbehaving agent. `PUT /blocked-ips/{ip}` blocks an address: the
+  hub closes every socket from it within a second, refuses its WebSocket upgrades, and refuses its `/storage`
+  requests with 403. `DELETE /agents/{agent_id}` blocks the address the agent last connected from the same way, and
+  drops the direct messages it sent that no recipient has acknowledged yet. With a NATS backplane a block reaches
+  every hub through the new `et-blocked` KV bucket, including hubs that join later. A local hub saves it in
+  `registry.yaml`. Both routes need `WS_ADMIN_TOKEN` set on the hub and presented as an `Authorization: Bearer`
+  token. While the variable is unset, the admin API answers 403. `et-cli block-ip --hub-url <url> --ip <address>` and
+  `et-cli evict-agent --hub-url <url> --agent-id <id>` send the requests, reading the token from `WS_ADMIN_TOKEN`.
+  There is no unblock yet; remove the address from `registry.yaml` or the KV bucket and restart the hubs.
