The -32603 completion-preservation guard coupled to the Claude/Kiro ACP
event shape. GPT-5.6 Sol leaves the finishing tool (goal_complete /
'multica issue comment add') parked at 'running' and titles the shell
tool with a name that does not normalize to 'terminal', so:
- isKiroIssueCommentAddTool's msg.Tool=='terminal' gate dropped the tool
use entirely, and
- with no completed/failed ToolCallUpdate, no ToolResult is emitted, so
the saw*Completed flags never flipped.
Completed tasks were therefore reversed to failed with
agent_error.provider_server_error ~17s after finishing their work.
Fix:
- Recognize comment-add by its command payload, independent of the
normalized tool title.
- Track each finishing tool along use / result / completed axes and
preserve completed when the -32603 close handshake follows a tool use
that never produced a terminal result. A genuinely failed ToolResult
still trips saw*Result and keeps the task failed.
Adds regression fixtures for the running-tool path (comment-add and
goal_complete) plus a failed-result safety case.
