Invoke each context helper as one literal Bash segment, with no `export` beforehand, no `env` or variable-assignment prefix, and no other command chained, piped, redirected, or substituted around it. If a script reports `SESSION_CONTEXT_HOME` is not set, stop and request a pane relaunch with the correct environment instead of deriving another context store. If no snapshot name is provided: 1. Run `list-contexts.sh` and collect the first-column snapshot names. 2. If none exist, report that and suggest `$knowledge:context-generate`; stop. 3. Ask the user to select a snapshot. Use structured `request_user_input` when it is available in the current mode and can represent the choices; otherwise ask one direct blocking question and wait. Do not infer a name. For either a provided or selected name, requ
