Tianyi Cui 56e252bed3 fix(host): fence the agentFor live fast path on the agent's own session
`agentFor` fenced subagent ownership through the attached session store
(`ctx.sessions.get`) and only then returned a live registered agent. A
registered agent whose session is ever absent from the attached store —
an invariant nothing in this package guarantees — would therefore be
handed out through generic Host routing unfenced, bypassing subagent
delivery entirely.

Fence `live.session` directly whenever a live agent exists, and keep the
attached-store check only for the not-live durable classification.
`ensureSession`'s race `.catch` already fences `live.session`; this makes
the fast path the same check instead of an asymmetric weaker one.

host/ — web-GUI host half

English | 中文

The host side of the dsh web GUI: the API gateway every client shape shares, and the plain HTTP server it rides on. The browser side lives in client/; the composed application is apps/cli serving apps/web. All product packages.

Package Role ctx key
apiproxy/ The shared API gateway: the zero-Node TS wire contract (src/api/), the fetch carrier pair (toFetchHandler host-side, AbstractApiClient client-side), and the host implementation over ctx.agents/ctx.workspace ctx.apiProxy
webserver/ Plain HTTP route-registration carrier: node:http server listening on activation; routes register as named exact/prefix handlers ctx.httpServer
directory-picker/ Workspace-directory picking seam: discriminated native/browse capability the gateway's picker RPCs delegate to ctx.directoryPicker
directory-picker-native/ Dual-face native interaction: OS-chooser backend (osascript / PowerShell / Zenity+KDialog, host-display only) + the browser half filling ui-workspace's directory-flow slots (registers ctx.directoryPicker)
directory-picker-browse/ Dual-face browse interaction: listing/creation primitives over Node stdlib (remote-capable) + the browser half rendering the in-app Select Workspace Directory dialog (registers ctx.directoryPicker)
directory-picker-auto/ Adaptive chooser: resolves the host's situation once at boot (bind host, SSH, display) and mounts the matching dual-face backend as an in-memory Loader entry (mounts a backend row)

apiproxy is transport-agnostic by design — it registers no routes; carriers wrap ctx.apiProxy themselves. The HTTP carrier route (with its /api browser-trust fence) is mounted by client/connection's node half, which is why that package lives in the client group: it owns both ends of the wire.
