Development record

The cloud hand-off cannot start a session on the Anthropic-hosted cloud environment: Claude Code names an environment at the start only for a self-hosted one (--environment takes a ccpool_ id and rejects Anthropic-hosted env_ ids, CLI reference read 2026-10-22), and the documented way to start an Anthropic-hosted session from a terminal, claude --cloud "<task>", takes its environment from the /remote-env default and its branch from the current checkout, and documents neither its output on creation (no machine-readable form is documented for creating, only for sending to an existing session) nor whether it exits or attaches; so scripts/cloud/connectors/claude/launch.sh refuses an env_ id rather than guess, and the planned hand-off (itd-2610120738075547) works only on a self-hosted environment until the create form is probed live
