Conversation
The `Ctrl+\` Debug Console modal is recreated fresh on every open and replays the whole in-memory ring buffer, so a `Ctrl+L` clear only lasted for the current session and re-populated on reopen. Persist a process- lifetime "cleared upto" cursor on the app: `DebugConsoleScreen` now takes `cleared_upto` to seed its render cursor and reports each clear back via `on_clear`, and the app seeds/stores the cursor across opens. This stays view-only; the shared buffer is untouched and newly logged records still appear after a clear. Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>

…hain-ai#4812) Clearing the Debug Console (`Ctrl+\`) traceback/log tail with `Ctrl+L` now persists across closing and reopening the console for the process lifetime, instead of re-populating from the in-memory buffer on the next open. --- The console modal is recreated fresh on every open and, on mount, replays everything still retained in the always-on in-memory ring buffer. `Ctrl+L` (`action_clear_view`) was deliberately a view-only clear that advanced only the current instance's render cursor, so closing and reopening replayed the buffer and the "cleared" records came back. This adds a process-lifetime "cleared upto" cursor owned by the app. `DebugConsoleScreen` gains keyword-only `cleared_upto` (seeds its render cursor so a prior clear is honored on open) and `on_clear` (reports the new cursor when `Ctrl+L` fires). `DeepAgentsApp` stores the cursor in `_debug_console_cleared_upto`, seeds each new console from it, and persists updates via the callback. The change stays strictly view-only: the shared ring buffer is never mutated, other diagnostics are unaffected, and records logged *after* a clear still appear. Clearing is by emission time, matching the existing in-session semantics.
