 ## Required regression tests
 
-Add tests for:
+Manual validation confirms the following behaviors through the GUI, TUI, and toolsrv execution paths:
 
-- client disconnect during blocking `Tread`;
-- response writer failure with many concurrent handlers;
+- blocking `Tread` via `statewait`;
 - `Tclunk` during a blocking read;
-- connection EOF with open blocking fids;
-- rename with open fids below the renamed path;
-- server shutdown during active reads;
-- `ListTools()` failure after action installation;
-- agent close during backend streaming and tool execution;
-- repeated profile switching with goroutine and FD counts;
-- feed consumer error and cancellation paths;
-- background sandbox setup failure;
-- background bypass execution;
-- dismissing a running process;
-- process kill followed by verified `Wait()`;
-- local and remote socket cleanup after startup failure;
-- remote stderr output after readiness;
-- concurrent process creation at the process limit;
-- abandoned completed-process GC;
-- bypass output exceeding the limit;
-- duplicate bypass resolution;
-- concurrent `Rdwr` read/write/close;
-- concurrent fid read/write/clunk;
-- repeated filesystem-tree construction and event-subscription cleanup;
-- repeated LSP start/stop calls.
+- client-facing session IDs, names, and namespace data;
+- toolsrv tool execution.

+One lifecycle scenario remains untested:
+
+- server shutdown during active reads.
+
+This is the next regression test target.
