+# v42: optional GUI vision must not block chat on RTX cooldown
+
+`desktop.gui` saves the guest screenshot and requests a helper workload slot without waiting. If another helper call or its required idle reservation is active, the tool returns `vision_deferred: true`. No visual interpretation is accepted, no remote call is sent and the cooldown remains unchanged. Required research calls retain their existing serialization and pacing.
+
+`mission_chat` exposes the existing `sandbox_run` tool to complete requested file edits inside the private guest, and instructs the master to read, edit and verify `/workspace/dashboard/index.html`. Reading HTML is not an edit; observing the GUI is unnecessary for HTML editing. Existing dashboard validation and host isolation remain in force.
+
+This fixes optional vision admission, not every possible source of latency. An admitted image request still uses the configured remote timeout. A chat request can still show `queued` while executing. It is not proof that the dashboard was edited or that the latest layout passed host validation.
+
+Verification: 123 remote-helper/campaign tests passed, including deferred cooldown, thread contention, preserved screenshot and unchanged idle reservation. Ruff and installer shell syntax checks passed. V100/RTX deployment requires the operator upgrade; no real hardware result is claimed here.
