+**What a session runs or obeys is the operator's, at the controller's terminal** (hq issue 340). A hook, a
+permission rule, any other managed setting, and a tool server run in, or decide what runs in, every session on the
+nodes they reach, as whoever starts it — the operator, whose account holds root. The tool runner acts for any caller of
+the mesh MCP server and is not told who called, so this module cannot tell the operator from an agent confined on
+another node. So these tools refuse, and say why and how it is done instead:

- for each kind — `skill`, `agent`, `command`, `hook`, `output_style`, `instructions` —
-  `claude_code_<kind>_list`, `_register`, `_unregister`. A skill is its files (`files`, or `content` for a
-  lone SKILL.md); a hook is an `event`, a `matcher`, a `command` and its scripts as `files`, with
-  `${HOOK_DIR}` in the command naming their directory. Hooks and settings take no home scope;
- `claude_code_settings_get`, `_set` (merged into the scope, or `replace`), `_clear`;
-  `claude_code_permission_add` and `_remove` for one allow, ask or deny rule. The agent refuses to loosen
-  its own settings: these are the operator's to call;
+- `claude_code_hook_register`, `claude_code_settings_set`, `claude_code_permission_add`, `claude_code_permission_remove`:
+  the operator sets hooks, permission rules and every other managed setting in this module's `managed_settings`
+  setting, `mesh-controller settings set claude-code '{"managed_settings": {…}}' [--node <node>]`, typed at the
+  controller's terminal. The controller refuses `managed_settings`, `mcp_servers` and `role` through any verb: a
+  mergeable file asks for every key its own content names;
+- `claude_code_mcp_register`: the operator sets tool servers in the `mcp_servers` setting the same way;
+- a skill, subagent or command that would run something by itself: a shell line the agent runs when it loads one
+  (`` !`…` ``, or a block opened with ```` ```! ````), or `hooks`, `mcpServers`, `permissionMode` or `allowed-tools`
+  in its front matter. Front matter is read as YAML (after a byte-order mark, flow style and merged keys
+  included); front matter that does not close, does not parse or is not a mapping is refused rather than guessed
+  at. A skill or command referring to a file with `@` that is not one of its own files is refused too: the agent
+  reads it into the prompt. A script beside a skill is taken: it runs only when the agent runs it, through the
+  session's own rules.
+
+What was registered before stays: a tool server is still rendered, and may be unregistered; a hook or settings the
+state still holds are never rendered, and `claude_code_hook_unregister` and `claude_code_settings_clear` remove
+them. `claude_code_registrations` lists everything registered, with who registered it, when, and whether it is
+rendered, beside what the operator set for this node at the terminal. Its `by` is the node whose tool runner served
+the call, never the caller, whom the runner is not told.
+
+**Text for every node or some is set at the controller's terminal too, for now** (hq issue 340, the operator's
+decision of 2026-10-09; a surface of the operator's own may update it later). Instruction sections, output styles,
+skills, commands and subagents at the `mesh` or `node` scope are refused through the tools, and the import tool is
+refused. They are keys of this module's settings, each text a list of its lines, because a setting holds no line
+break: `instructions`, `output_styles`, `commands` and `agents` map a name to its text; `skills` maps a name to its
+files, each a list of lines. For example `mesh-controller settings set claude-code '{"instructions": {"conventions":
+["Commit in the imperative.", "", "Test before pushing."]}}'`. They land where a registration did, laid over what was
+registered before; what the operator writes there is not judged, but an item that is not well formed is left out and
+said in the render's answer. What was registered before is still rendered and may be unregistered.
+
+The home scope is registered through the tools **only where the home belongs to an agent account of its own**
+(hq ADR 0266, issue 340), and only for the node whose module serves the call. Where the agent runs as the operator,
+the home is the operator's own `~/.claude`, whose rules and skills load in every session the operator starts, and
+the tool runner cannot tell the operator from an agent: refused there, and for any other node, whose home cannot be
+judged from here (call that node's own tool). A home item on the bus is never placed in the operator's own home,
+and what the module placed there before is taken back unless the person changed it. `claude_code_home_remove` and
+`claude_code_home_restore` are refused the same way wherever the home is the operator's own: removing a rule changes
+what a session obeys as surely as placing one. Where it is taken:
+
+- for each kind — `skill`, `agent`, `command`, `output_style`, `instructions` — `claude_code_<kind>_list`,
+  `_register`, `_unregister`. A skill is its files (`files`, or `content` for a lone SKILL.md);
+- `claude_code_hook_list` and `_unregister`, `claude_code_settings_get` (the managed settings as written, the
+  operator's setting, and what was registered before and is not rendered) and `_clear`;
 - `claude_code_config_list`, `_show` (one registration in full), `_status` (what applies here, the plugin
  as written, and the home's own items — which the mesh placed, which share a name with a mesh item, which
