+
+## Decision
+
+Routing decision: `implementation_ready`
+
+Reason:
+- Ticket body は in-flight LLM response reconnect snapshot の問題、affected blocks、protocol/pod/TUI relevant files、acceptance criteria、validation が具体化されている。
+- `readiness: implementation_ready` で、relations / orchestration plan に blocker はない。
+- Requirements sync で Deno refinement は誤付与として分離済みで、この Ticket は original protocol reconnect scope に戻されている。
+- 同時 queued の `00001KVMV03QY` は frontend Deno tooling migration であり、この Ticket の protocol/pod/TUI stream-state work と主対象が異なるため並列実装可能と判断する。
+- Orchestrator worktree は clean on `orchestration` at `b4786b40` で、対象 Ticket 用 worktree / branch は未作成。
+
+Evidence checked:
+- Ticket body / thread / artifacts via `TicketShow` and direct `item.md` read。
+- `TicketRelationQuery(00001KVMT2J25)`: no relations / blockers。
+- `TicketOrchestrationPlanQuery(00001KVMT2J25)`: no records。
+- Orchestrator git state / worktree list / branch list checked from `/home/hare/Projects/yoi/.worktree/orchestration` only。
+- Bounded code map:
+  - `crates/protocol/src/lib.rs`: `Event::Snapshot`, `TextDelta`, `ThinkingDelta`, `ToolCallArgsDelta`, serialization tests。
+  - `crates/pod/src/segment_log_sink.rs`: committed `LogEntry` snapshot / live entry receiver。
+  - `crates/pod/src/controller.rs`: direct broadcast of streaming deltas and current controller comments around stream reconstruction。
+  - `crates/pod/src/ipc/server.rs`: connect-time snapshot event construction。
+  - `crates/tui/src/app.rs`: `restore_snapshot` and live delta handling for text/thinking/tool-call args。
+
+IntentPacket:
+
+Intent:
+- Ensure late attach / reconnect during an in-flight LLM response can display already-generated unfinished text/thinking/tool-call args, then continue live deltas without gaps or duplicates。
+
+Binding decisions / invariants:
+- Fix at protocol/pod state level, not TUI-only workaround。
+- Do not persist unfinished model output as finalized assistant history。
+- Do not mutate/replay provider stream itself。
+- Preserve committed session-log gap-free semantics。
+- Preserve post-run reconnect behavior from finalized Snapshot entries。
+- No hidden context/history injection。
+- Keep in-flight snapshot bounded and typed; if large/unbounded policy is required, escalate。
+
+Requirements / acceptance criteria:
+- New client connecting during response sees unfinished assistant text, thinking/reasoning, and tool-call args generated before connect。
+- Live deltas after connect append to same logical block without missing or duplicated content。
+- Completed run reconnect still restores finalized transcript from normal Snapshot entries。
+- Snapshot/live boundary gap-free / duplicate-free behavior is tested。
+- TUI Snapshot restore + live delta handling has regression coverage。
+- Focused validation covers protocol/pod/TUI relevant paths。
+
+Implementation latitude:
+- Add structured `in_flight` state to `Event::Snapshot`, or implement bounded/sequence replay buffer if cleaner。
+- Controller/Pod may keep current accumulators for text/thinking/tool-call args。
+- TUI may seed unfinished blocks from Snapshot and continue applying live deltas to the same block。
+- Wire compatibility should be minimal; prioritize type safety and maintainability。
+
+Escalate if:
+- Design requires persisting unfinished output as durable history item。
+- In-flight snapshot state becomes large enough to need truncation/bounding policy beyond a straightforward current-turn accumulator。
+- Public protocol compatibility policy becomes a product decision。
+- Scope spreads to Dashboard/Pod list preview or broader UX surfaces beyond TUI/console attach。
+
+Validation plan:
+- `cargo fmt --check`
+- Focused `cargo test -p protocol` roundtrip/serialization tests for snapshot in-flight state。
+- Focused `cargo test -p pod` tests for connect-time snapshot/live boundary and accumulator behavior。
+- Focused `cargo test -p tui` tests for snapshot seeding plus live delta continuation。
+- `cargo check -p protocol -p pod -p tui`
+- `git diff --check`
+- `yoi ticket doctor`。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVMT2J25`.
+
+Implementation commit:
+- `74aca6f6 fix: snapshot in-flight stream state`
+
+Changed areas:
+- `crates/protocol/src/lib.rs`
+  - Added typed `InFlightSnapshot` / `InFlightBlock` state on `Event::Snapshot`。
+  - Added serialization/default compatibility coverage。
+- `crates/pod/src/in_flight.rs`
+  - New in-flight accumulator for assistant text, thinking/reasoning, and tool-call args。
+  - Snapshot/live boundary tests for no gap/duplicate。
+- `crates/pod/src/controller.rs`
+  - Streaming callbacks update the in-flight accumulator and broadcast live deltas from the same path。
+- `crates/pod/src/ipc/alerter.rs`, `crates/pod/src/ipc/server.rs`
+  - Connect-time snapshot now includes alerts plus typed in-flight stream state while subscribing live events。
+- `crates/pod/src/pod.rs`
+  - Clears matching in-flight blocks once committed assistant items reach durable session log entries。
+- `crates/tui/src/app.rs`
+  - Snapshot restore seeds unfinished assistant text/thinking/tool-call blocks。
+  - Live deltas continue those seeded blocks。
+  - Added regression coverage for snapshot seeding plus live continuation。
+- Other touched files update test Snapshot constructors for the new `in_flight` field。
+
+Coder validation reported:
+- `cargo fmt --all --check`: passed
+- `cargo test -p protocol`: passed
+- `cargo test -p protocol event_snapshot_in_flight_roundtrip_and_default`: passed
+- `cargo test -p pod in_flight`: passed
+- `cargo test -p pod subscribe_with_alerts_and_in_flight_snapshot_splits_snapshot_and_live_deltas`: passed

+- `cargo check -p protocol -p pod -p tui`: passed
+- `git diff --check`: passed
+- `target/debug/yoi ticket doctor`: passed
+
+Known unrelated validation note:
+- Full `cargo test -p pod` still fails on two prompt-resource assertion tests unrelated to this change:
+  - `prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`
+  - `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`
+  - Both assert missing text: `worktree status, diff, and test results`。
+
+Orchestrator evidence checked:
+- Implementation worktree is clean on `impl/00001KVMT2J25-inflight-snapshot`。
+- HEAD is `74aca6f6`。
+- Diff `155e039e..HEAD` touches 17 protocol/pod/TUI files, adding `crates/pod/src/in_flight.rs` and updating Snapshot constructors/tests。

+Intent:
+- Move Workspace web SPA frontend tooling from npm/Node-primary to Deno-primary while keeping SvelteKit static SPA and Rust backend authority unchanged。

+Binding decisions / invariants:
+- This is frontend tooling migration only; do not change Workspace backend API authority, Ticket/Objectives authority, or `.yoi` canonical record workflows。
+- Keep static SPA and Rust backend static-serving boundary。

+- Avoid ambiguous dual source-of-truth between npm and Deno。
+- Generated artifacts must remain out of git and Nix package source。
+- `00001KVMT2J25` protocol reconnect work remains separate。
+
+Requirements / acceptance criteria:
+- `web/workspace` check/build succeeds through Deno commands。
+- Add/clarify Deno project config such as `deno.json`/`deno.lock`/`deno task`。
+- README and project files make normal Deno install/check/build workflow clear。
+- Remove npm lockfile/scripts/Node-only guidance if unnecessary; if any npm/Node metadata remains, document whether it is compatibility artifact or canonical source-of-truth。
+- Preserve static output usable by Rust backend, default `web/workspace/build/` unless deliberately changed and documented。
+- Keep `web/workspace/build/`, `.svelte-kit/`, `node_modules` or Deno equivalents ignored/source-filtered。

+  - `web/workspace/deno.lock`

+
+Blocking issues:
+- None。
+
+Findings:
+- Deno is now the clear frontend tooling source of truth:
+  - `web/workspace/deno.json` defines Deno tasks and pinned npm-compat dependencies。
+  - `web/workspace/deno.lock` is committed。
+  - `package-lock.json` is removed。
+  - `package.json` is reduced to package metadata only, with no scripts or dependencies。
+  - README explicitly says canonical tooling is `deno.json` / `deno.lock`, and `package.json` is compatibility metadata only。
+- Static SPA assumptions are preserved:
+  - `svelte.config.js` still uses `@sveltejs/adapter-static`。
+  - output remains `web/workspace/build/`。
+  - `+layout.ts` still has `ssr = false` and `prerender = true`。
+  - diff does not touch Rust backend/API authority, protocol reconnect scope, or `.yoi` canonical records。
+- Generated artifact boundaries remain intact:
+  - `.gitignore` ignores `node_modules`, `.svelte-kit`, and `build`。
+  - `package.nix` still excludes `web/workspace/node_modules`, `web/workspace/.svelte-kit`, and `web/workspace/build`。
+  - `devshell.nix` already provides `deno`。
+
+Non-blocking concern:
+- `deno task build` succeeds but upstream SvelteKit/Vite emits generic `Run npm run preview to preview your production build locally.` The project README and `deno.json` correctly provide `deno task preview`, and there are no npm scripts in the repo, so this is not blocking。
+
+Reviewer validation:
+- `git diff --check 155e039e..66f04e04`: passed
+- `cd web/workspace && deno --version && rm -rf node_modules .svelte-kit build && deno task check && deno task build`: passed with Deno `2.7.14`; `svelte-check found 0 errors and 0 warnings`; build completed to `build`
+- `cd web/workspace && deno task install`: passed
+- `target/debug/yoi ticket doctor`: passed (`doctor: ok`)
+- `nix build .#yoi --no-link`: passed
+- `git show --no-patch --format='%H %s' 66f04e04` and `git diff --quiet 66f04e04..HEAD`: HEAD matches implementation commit
+
+Generated artifacts:
+- Reviewer did not clean generated ignored artifacts after validation。
+- Ignored artifacts present in implementation worktree:
+  - `web/workspace/node_modules/`
+  - `web/workspace/.svelte-kit/`
+  - `web/workspace/build/`
+- `git check-ignore -v` confirms all three are ignored by `web/workspace/.gitignore`; `package.nix` excludes same paths。
+
+Worktree status:
+- Tracked status clean at `66f04e04` on `impl/00001KVMV03QY-workspace-spa-deno`。

+## 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。

+
+## 完了
+
+Workspace web SPA の frontend tooling を npm/Node-primary から Deno-primary に移行し、Orchestrator worktree の `orchestration` branch に統合した。
+
+主な成果:
+- `web/workspace/deno.json` を追加し、Deno task を canonical workflow にした。
+- `web/workspace/deno.lock` を追加。
+- `web/workspace/package-lock.json` を削除。
+- `web/workspace/package.json` は SvelteKit/Vite ecosystem compatibility metadata のみに縮小し、scripts/dependencies を削除。
+- README を Deno workflow (`deno install`, `deno task check`, `deno task build`, `deno task preview`) と source-of-truth 説明に更新。
+- Static SPA output path `web/workspace/build/` と `@sveltejs/adapter-static` assumptions を維持。
+- Rust backend/static serving code、Workspace API authority、Ticket/Objectives authority、`.yoi` canonical record workflows には変更を加えていない。
+- Generated artifacts (`node_modules`, `.svelte-kit`, `build`) は ignored/source-filtered のまま。
+
+統合・検証:
+- Merge commit: `6dc78e3f merge: workspace spa deno tooling`
+- Implementation commit: `66f04e04 feat: migrate workspace spa tooling to deno`
+- Reviewer final verdict: approve
+- Validation passed: `git diff --check HEAD^1..HEAD`, `deno task check`, `deno task build`, `deno task install`, `cargo check -p yoi-workspace-server`, `cargo run -p yoi -- ticket doctor`, and `nix build .#yoi --no-link`。
+
+範囲外:
+- Backend API / static serving implementation は変更していない。
+- Protocol reconnect work (`00001KVMT2J25`) には触れていない。
+- SSR / Deno runtime server / Deno Deploy assumptions は追加していない。

+## Implementation report
+
+Post-close cleanup completed。
+
+- Stopped child Pods and reclaimed scope:
+  - `yoi-coder-00001KVMV03QY`
+  - `yoi-reviewer-00001KVMV03QY-r1`
+- Removed ignored frontend validation artifacts from child worktree before worktree removal:
+  - `web/workspace/node_modules/`
+  - `web/workspace/.svelte-kit/`
+  - `web/workspace/build/`
+- Removed implementation worktree:
+  - `/home/hare/Projects/yoi/.worktree/00001KVMV03QY-workspace-spa-deno`
+- Deleted implementation branch:
+  - `impl/00001KVMV03QY-workspace-spa-deno`
+- Orchestrator worktree remains clean on `orchestration` at `54d325ae`。
+
+Root/original workspace was not used for merge/validation/cleanup operations。
