+## Implementation report
+
+Implementation start report:
+
+- Created child implementation worktree:
+  - `/home/hare/Projects/yoi/.worktree/00001KVSKJ0EA-dashboard-no-auto-selection`
+- Created branch:
+  - `impl/00001KVSKJ0EA-dashboard-no-auto-selection`
+- Base commit:
+  - `4cda83b7 ticket: accept workspace identity and selection work`
+- Confirmed tracked Ticket project records are visible in the child worktree。
+- Confirmed `.yoi/memory` has no tracked/untracked entries in the child worktree check。
+- Spawned sibling Coder Pod:
+  - `yoi-coder-00001KVSKJ0EA`
+- Coder scope:
+  - read: `/home/hare/Projects/yoi`
+  - write: `/home/hare/Projects/yoi/.worktree/00001KVSKJ0EA-dashboard-no-auto-selection`
+
+Parallelization note:
+- `00001KVSKGDYS` is active separately and targets Workspace backend identity persistence. This Ticket should stay limited to TUI Dashboard selection semantics。
+
+Next action:
+- Wait for Coder implementation report, then spawn Reviewer read-only for the implementation diff。
