Both merge-helper ConPTY sessions loaded PromptKind.MergeHelper, so the
post-handoff session received the phase 0-2 dedupe/enhance instructions and was
told to ignore them by its brief alone.
Split into MergeHelperTriage (phases 0-2 + handoff) and MergeHelperExecute
(phases 3-5), so each session carries only its own phases. Consolidated the
generic ask-the-user rule to one place per prompt, scoped Phase 5's summary to
what the execute session actually knows, and moved the dedupe/enhance bilanz to
the triage handoff. Regression guards assert neither prompt carries the other's
phase headings and that the shared-checkout git rule stays in execute.
Submit for Review is now disabled while a ConPTY pane is starting, has
failed to launch, or has already exited, and MissionControlViewModel
guards against a rapid double-click racing two SubmitTaskForReviewAsync
calls. A failed launch no longer permanently occupies its TaskId dedupe
slot -- a Retry button re-fetches the launch spec and restarts the pane
in place. CloseConPtySession/Dispose now also unsubscribe
SubmitForReviewRequested, matching the other pane event handlers. Also
fixes the pre-existing nullable-dereference warning in
IslandsShellViewModel.SyncInteractiveSessionChips.
Bump conpty-sessions.md's verified-against commit to d84607f and add a
section covering the CanSendToQueue / EnqueueTaskAsync interactive-session
gate and the switch to routing through the worker hub.
## Der Zweifel
Ein autonomer Agent und eine interaktive Session sollen sich unterschiedlich verhalten. Unklar war, ob beide denselben System-Prompt mitbekommen.
## Vorbefund (2026-08-05, beim Verfeinern erhoben — **selbst nachpruefen, nicht uebernehmen**)
Sie teilen ihn **nicht**. Pro Startweg:
| Startweg | Einstieg | System-Prompt |
|---|---|---|
| Autonomer Run | `ClaudeArgsBuilder.cs:69-73`
