- Keep Control UI chat sends bound to the history-backed session id across reconnects.
- Accept chat.send sessionId at the gateway/protocol boundary and update generated Swift models.
- Resume the last selected TUI session for the same gateway/agent/scope when still present.
Validated by exact-SHA CI on PR #75948.
Keep WebChat runtime context available to the model while persisting only the transcript-facing user prompt across gateway, CLI, queued follow-up, and embedded Pi paths.
Adds regression coverage for history sanitization, CLI transcript persistence, media-only auto-reply prompts, and embedded Pi prompt rewrite against a real SessionManager file.
