+## Implementation report
+
+Fourth follow-up implementation report after review request_changes:
+
+対応内容:
+
+1. 指摘箇所の Worker terminology 更新
+- `docs/development/workflows.md`
+  - `## Child Pods` → `## Child Workers`
+  - `Child Pods may commit ...` → `Child Workers may commit ...`
+- `docs/development/work-items.md`
+  - `Inside Pods ...` → `Inside Workers ...`
+  - `Ticket tools inside Pods` → `Ticket tools inside Workers`
+  - `Pods with the Ticket built-in feature ...` → `Workers with the Ticket built-in feature ...`
+  - `spawn coder/reviewer Pods ...` → `spawn coder/reviewer Workers ...`
+  - `coder Pods ...` → `coder Workers ...`
+- `tests/e2e/tests/panel.rs`
+  - `fixture blocks host Pod launch` → `fixture blocks host Worker launch`
+  - `host/fixture runtime Pod marker ...` → `host/fixture runtime Worker marker ...`
+
+2. 追加で見つかった docs/tests の active Pod 表現も更新
+- `docs/design/tool-permissions-scope.md`: `Child Pods` → `Child Workers`
+- `docs/design/compaction.md`: `long-running Pods` → `long-running Workers`
+- `docs/design/memory-knowledge.md`: `normal Pods` → `normal Workers`
+- `docs/design/plugin-packages.md`: `Restored Pods` → `Restored Workers`
+- `docs/development/environment.md`: `spawned Pods` → `spawned Workers`
+- `tests/e2e/tests/rewind.rs`: `single-pod rewind fixture` → `single-worker rewind fixture`
+- `tests/e2e/tests/panel.rs`: active test helper/fixture naming and diagnostics updated to Worker terminology.
+
+Validation:
+- `cargo test -p worker`: success
+- `cargo test -p yoi`: success
+- `cargo check -p yoi`: success
+- `cargo test -p protocol --features typescript`: success
+- `cargo check -p yoi-e2e`: success
+- `cd web/workspace && deno task check`: success
+- `git diff --check`: success
+- `nix build .#yoi --no-link`: success
