+## Implementation report
+
+Reviewer r1 approvalを受けて、実装ブランチを Orchestrator worktree の `orchestration` branch に統合した。
+
+統合:
+- Merge commit: `6dc78e3f merge: workspace spa deno tooling`
+- Merged branch: `impl/00001KVMV03QY-workspace-spa-deno`
+- Implementation commit:
+  - `66f04e04 feat: migrate workspace spa tooling to deno`
+
+Orchestrator worktree validation:
+- `git diff --check HEAD^1..HEAD`: passed
+- `cd web/workspace && rm -rf node_modules .svelte-kit build && deno task check`: passed (`svelte-check found 0 errors and 0 warnings`)
+- `cd web/workspace && deno task build`: passed and wrote static site to `build/`
+- `cd web/workspace && deno task install`: passed
+- `cargo check -p yoi-workspace-server`: passed
+- `cargo run -p yoi -- ticket doctor`: passed (`doctor: ok`)
+- `nix build .#yoi --no-link`: passed
+
+Validation generated ignored frontend artifacts in Orchestrator worktree:
+- `web/workspace/node_modules/`
+- `web/workspace/.svelte-kit/`
+- `web/workspace/build/`
+
+These were removed after validation. Final Orchestrator worktree status after validation cleanup is clean on `orchestration` at `6dc78e3f`。
+
+Non-blocking note:
+- Upstream SvelteKit/Vite still prints generic `Run npm run preview...` during build; project README and `deno.json` provide `deno task preview`, and no npm scripts remain, so this is accepted as upstream output rather than project guidance。
