+## Review: approve

+Focused re-review result: approve
+
+Evidence:
+- Verified follow-up `bc48094d` with clean implementation worktree。
+- Focused greps for `ActiveWorkflow|active_workflow|Active workflow`, `workflow_invoke`, `resources/workflows`, `.yoi/workflow`, `workflow invocation`, `Resident workflows`, and workflow completion/resolver surfaces are clean。
+- `/` is no longer a web completion sigil and protocol completion docs now only cover file/Knowledge。
+- `live_system_snapshot_replaces_task_store` now uses active `task_reminder` and passes。
+- `live_legacy_workflow_system_item_is_ignored` also passes。
+- `git diff --check` and `cargo check -p yoi` pass。
+- Legacy persisted `kind: "workflow"` remains bounded to `LegacyIgnored` / diagnostic-or-drop behavior and TUI ignores it。
+- No broad first-class Skills implementation observed; remaining workflow text is ticket lifecycle naming, legacy ignore/rejection tests/docs, or historical/non-active comments, not active Workflow invocation/resource authority。
+
+Blockers: none。
