The creation header names the preset a session STARTED with and is frozen, which is correct — it is a creation fact. Switching is legal only while a session is blank, and that looked like enough: no history exists yet. It is not, because the switch's effect outlives the blank window. The user switches, then sends the first message; every turn from there runs under the new composition while the header still names the old one. The session is then locked around a misrecorded preset, and resume reads the header to rebuild it — composing one preset's tools over a history another produced, which is exactly the replay the blank-only lock exists to prevent, reached by another route. A picker showed `standard` for a session running `core-web`. A switch is now an `agent-preset/selected` event appended after the swap commits, and `resolveSessionPreset()` (last selection, else the header) is what every reconstruction reads: the summary, resume, the conflict guard, and the fork introduced one layer down.
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 booting the dsh-base bundle serving apps/web. All product packages.

apiproxy remains transport-independent; client/connection supplies the browser/HTTP carrier. Picker implementations replace one another behind the shared seam.
