+## Implementation report
+
+Implemented Workspace Console tool-call grouping.
+
+- Tool lifecycle events now update one `Call · <tool>` console line keyed by call id.
+- Args streaming, call completion, and tool result output are folded into that line instead of producing separate `tool call` / `tool call done` / `tool result` rows.
+- Added generic tool rendering plus TUI-aligned special summaries for Read, Write, Edit, Glob, and Grep; Bash renders the command and output in the same Call block.
+- In-flight tool snapshots now render as Call blocks as well.
+- Added model tests for completed Bash call aggregation and streaming Read call updates.
+
+Validation:
+- cd web/workspace && deno task check
+- cd web/workspace && deno task test
+- git diff --check
+- nix build .#yoi --no-link
