Review the Devcenter frontend locally
This is the public evaluation path. It runs the frontend against process-local sample data, is visibly marked as review mode, and contacts no Identity, Connector, model-provider, or Agent Platform service. It needs no beyond10x account, cluster, service credential, or private artifact.
The hosted-workbench sample includes the real vendored Ghostty renderer and terminal framing over a
local review WebSocket. Its prompt is a deterministic protocol emulator, clearly labelled in the
terminal; it does not run commands or stand in for the separate Workspace-to-Substrate acceptance
lane. pwd, ls, whoami, and top return labelled sample output so keyboard, ANSI, resize,
multiple-tab, reconnect, detach, and Kill interactions can be reviewed without a host-shell escape.
