Code Mode was a deployment-wide field on the host `tools` row: a deployment ran every session that way or none. The obvious product shape — 代码模式 beside 标准/极简/创造 in the preset picker — had nothing to hang on. The registry itself cannot move into a preset; the agent loop's scheduler, the api-proxy's presenters, and every tool plugin are its consumers. So split the registry from its projection: `presentAs(mode)` writes one cell on the calling agent's scope layer, exactly as `restrict()` does, and the three reads that decided presentation take that scope's mode instead of the service's. The config `mode` becomes the default agents shadow rather than a process-wide fact. Two consequences are load-bearing. `run_code` now enters a view only for scopes whose own mode presents it — a native agent must not find it dispatchable because another agent in the process does — and the reserved name holds whatever the configured mode, since any agent may select a code mode later. `dsh-agent-tool-mode` is the row a preset carries to declare this. A code mode waits for the host's `codeRuntime` rather than assuming it, so a runtime-less deployment fails the preset at mount, naming the row, instead of at the session's first request. The shipped `code` preset is `standard` plus that row, ordered second.

/**
|
|
* Agent-plane presentation selector: the row an agent preset carries to say
|
|
* which form of its tools the model sees.
|
|
*
|
|
* The tool registry itself stays on the host plane — the agent loop's
|
|
* scheduler, the API proxy's presenters, and every tool plugin are all its
|
|
* consumers, so it cannot move into a preset. What a preset CAN own is the
|
|
* presentation: `ctx.tools.presentAs()` declares it for the mounting agent
|
|
* alone, so a Code Mode agent runs beside native ones in one process.
|
|
*
|
|
* A code mode needs a TypeScript code runtime, which is a host-plane service
|
|
* ([`dsh-code-runtime-worker`](../../code-runtime/code-runtime-worker/README.md)).
|
|
* This row therefore waits for it rather than assuming it: a preset selecting
|
|
* Code Mode against a deployment that composes no runtime fails at mount, named
|
|
* in the preset's own activation audit, instead of at the first prompt.
|
