+## Implementation report
+
+Implementation kickoff:
+
+- Worktree created: `/home/hare/Projects/yoi/.worktree/00001KW2GCPYF-worker-console-redesign`
+- Branch: `work/00001KW2GCPYF-worker-console-redesign`
+- Coder Worker spawned: `yoi-coder-00001KW2GCPYF-worker-console`
+
+Scope notes:
+- Coder has read access to the implementation worktree and non-recursive workspace root identity path needed by runtime startup.
+- Coder write scope is limited to `web/workspace/**`, `crates/workspace-server/**`, root `Cargo.toml`, `Cargo.lock`, and `package.nix` if dependency/package changes are needed.
+- Coder is instructed not to modify Ticket records and not to operate in root/orchestration worktrees.
