<!-- event: decision author: yoi-orchestrator at: 2026-06-23T05:41:02Z -->

## Decision

Routing decision: `implementation_ready`

Reason:
- Ticket body has concrete requirements for protocol DTO feature-splitting, generated TypeScript types, generated-output drift check, and Workspace web integration stance。
- No blocking relations / orchestration plan records exist。
- Current queued Ticket is this Ticket only。
- Orchestrator worktree is clean on `orchestration` at `615c0250`; target worktree / branch is not present。
- Existing code map confirms `crates/protocol` currently has `tokio` dependency and `stream.rs` enabled unconditionally, while frontend has local hand-written types for Workspace entities but no generated protocol types yet。

IntentPacket:

Intent:
- Make `crates/protocol` the Rust authority for Pod wire DTOs and generate Workspace web TypeScript types from those DTOs instead of hand-writing protocol mirror types。

Binding decisions / invariants:
- DTO authority remains Rust `crates/protocol`; do not create a separate web-only protocol authority。
- Browser must not connect directly to Pod Unix sockets。
- Backend proxy may be design-recorded or minimally scaffolded, but must preserve Worker identity resolution and method allow/block boundary; do not implement broad Worker operation UI in this Ticket。
- `stream.rs` / JSONL tokio transport should be optional behind a default `stream` feature; DTO-only crate should compile without tokio for wasm/no-default-features。
- Generated TypeScript must reflect serde wire shape for tagged enums / rename conventions as closely as practical。
- Generated artifacts should be committed only if they are intended import artifacts and have a drift check。
- Avoid broad protocol redesign or permission-model invention。

Requirements / acceptance criteria:
- `cargo check -p protocol --target wasm32-unknown-unknown --no-default-features` passes, or if target installation is unavailable in environment, the code is structured correctly and validation limitation is documented。
- Protocol root types at least include `Method`, `Event`, `Segment`, and related DTOs needed by Worker operation UI / stream display。
- Workspace web can import generated protocol TypeScript types from a generated directory/file。
- Generated-output drift check exists, e.g. cargo test/generator check that fails if committed generated TS is stale。
- `cargo test -p protocol` passes。
- Deno check/build passes。
- `git diff --check` and `nix build .#yoi --no-link` pass if dependencies/package hash changed。
- Backend proxy stance is represented in implementation or design notes without direct browser-to-Pod socket exposure。

Implementation latitude:
- Use `ts-rs` if it fits; otherwise choose a small generator that preserves serde-tagged shape and is reviewable。
- Put generated types under `web/workspace/src/lib/generated/protocol.ts` or similarly clear generated path。
- Generator can be a test in `protocol`, a small binary/example, or another deterministic Cargo path; keep it simple and reproducible。
- If adding `ts-rs` feature annotations is invasive, cover a useful initial subset and document unsupported types clearly, but keep `Method`, `Event`, and `Segment` included。
- For `uuid::Uuid`, `PathBuf`, `serde_json::Value`, choose clear TS representations (`string`, `unknown`/JSON value, etc.) and document/test them。

Escalate if:
- `ts-rs` cannot represent current serde-tagged enums without unacceptable manual mirrors。
- Making protocol DTOs wasm/no-default-features compatible requires broad type redesign beyond optional `stream` feature。
- Generated file would include secret/project-local content or nondeterministic ordering。
- Backend proxy implementation scope expands into full Worker operation UI/session WebSocket implementation。

Validation plan:
- `cargo fmt --check`
- `cargo test -p protocol`
- `cargo check -p protocol --target wasm32-unknown-unknown --no-default-features`
- Type generation drift check command/test。
- `cd web/workspace && deno task check && deno task build`
- `git diff --check`
- `cargo run -p yoi -- ticket doctor`
- `nix build .#yoi --no-link` if Cargo.lock/package.nix/source behavior changes。

<!-- event: review author: yoi-reviewer-00001KVSEBF56-r1 at: 2026-06-23T06:16:54Z status: approve -->

## Review: approve

Verdict: `approve`

確認範囲:
- Ticket authority:
  - `.yoi/tickets/00001KVSEBF56/item.md`
  - `.yoi/tickets/00001KVSEBF56/thread.md`
- Diff `746c51c7..a13fb693`:
  - `crates/protocol/Cargo.toml`
  - `crates/protocol/src/lib.rs`
  - `crates/protocol/src/typescript.rs`
  - `crates/protocol/examples/generate_typescript.rs`
  - `web/workspace/src/lib/generated/protocol.ts`
  - `web/workspace/src/lib/workspace-sidebar/types.ts`
  - `crates/workspace-server/src/server.rs`
  - `Cargo.lock`
  - `package.nix`

Blocking issues:
- None。

Non-blocking concerns:
- `cargo test -p protocol --features typescript` emits `ts-rs` warnings for `#[serde(other)]` on `Segment::Unknown`: `ts-rs failed to parse this attribute. It will be ignored.` The generated artifact still includes `{ "kind": "unknown" }`, and this does not break current validation, but TS generator is not fully understanding serde fallback semantics。
- Some `Option<T>` fields with `skip_serializing_if = "Option::is_none"` are generated as required nullable rather than optional nullable, e.g. `RewindTarget.disabled_reason: string | null` and `warning: string | null`. Acceptable for this initial generated-types ticket, but future UI code should be careful because runtime JSON may omit those fields。

Review findings:
- `crates/protocol` remains Rust DTO authority。
- `stream` is now an optional default feature:
  - `default = ["stream"]`
  - `stream = ["dep:tokio"]`
  - `tokio` is optional。
- DTO-only/no-default protocol build compiles for wasm without `tokio`。
- `typescript` feature is optional and uses `ts-rs`。
- Generated TS root includes `Method`, `Event`, `Segment`, plus related DTOs such as `PodEvent`, `ScopeRule`, `Greeting`, `InFlight*`, rewind DTOs, completion DTOs, status/result/error enums。
- Generated TS file is committed at `web/workspace/src/lib/generated/protocol.ts`。
- Workspace web re-exports generated root protocol types as `PodProtocolMethod`, `PodProtocolEvent`, and `PodProtocolSegment`。
- Generated TS tagged enums and casing match observed serde wire shape for critical roots:
  - `Method`: `{ "method": "...", "params": ... }`
  - `Event`: `{ "event": "...", "data": ... }`
  - `Segment` / `PodEvent` / `InFlightBlock`: internal `"kind"` tags with snake_case variants。
- Drift check `generated_protocol_types_are_current` compares committed generated artifact to deterministic generator output。
- Backend proxy stance is represented in Workspace API extension-point notes and does not add direct browser-to-Pod socket access or broad Worker operation UI。

Reviewer validation:
- `cargo fmt --check`: passed
- `git diff --check 746c51c7..HEAD`: passed
- `cargo test -p protocol`: passed (`40 passed`)
- `cargo test -p protocol --features typescript generated_protocol_types_are_current`: passed; emitted non-blocking `ts-rs` warning for `serde(other)`。
- `cargo test -p protocol --features typescript`: passed (`41 passed`); emitted same non-blocking warning。
- `cargo check -p protocol --target wasm32-unknown-unknown --no-default-features`: passed
- `cd web/workspace && deno task check && deno task build`: passed (`svelte-check found 0 errors and 0 warnings`; build succeeded)
- `cargo run -p yoi -- ticket doctor`: passed (`doctor: ok`)
- `nix build .#yoi --no-link`: passed

Generated artifact status:
- `web/workspace/src/lib/generated/protocol.ts` remained unchanged after validation。
- SHA-256 after validation: `3984a043ded1179545656e5402171c49b2d22b5529aa17f016b675e394b7e553`。

Worktree status:
- Clean on `impl/00001KVSEBF56-protocol-typescript-types` at `a13fb693`。

## 完了

Protocol crate 由来の Workspace web TypeScript type generation を実装し、Orchestrator worktree の `orchestration` branch に統合した。

主な成果:
- `crates/protocol` の `stream` module / tokio dependency を default `stream` feature に分離し、DTO-only build で tokio を不要にした。
- Optional `typescript` feature と `ts-rs` による TypeScript export を追加。
- Protocol DTOs に `cfg_attr(feature = "typescript", derive(ts_rs::TS))` を追加。
- Deterministic generator を追加:
  - `crates/protocol/src/typescript.rs`
  - `crates/protocol/examples/generate_typescript.rs`
- Drift check を追加:
  - `cargo test -p protocol --features typescript generated_protocol_types_are_current`
- Generated artifact を追加:
  - `web/workspace/src/lib/generated/protocol.ts`
- Workspace web が generated root protocol types を re-export:
  - `PodProtocolMethod`
  - `PodProtocolEvent`
  - `PodProtocolSegment`
- Workspace backend extension-point notes に、browser が Pod Unix socket に直接接続せず、将来の backend proxy が Worker identity と method allow/block boundary を enforce する方針を記録。
- `Cargo.lock` と `package.nix` cargo hash を更新。

統合・検証:
- Merge commit: `9728b533 merge: protocol typescript generation`
- Implementation commit: `a13fb693 protocol: generate workspace TypeScript types`
- Reviewer final verdict: approve
- Validation passed: `cargo fmt --check`, `git diff --check HEAD^1..HEAD`, `cargo test -p protocol`, `cargo test -p protocol --features typescript generated_protocol_types_are_current`, `cargo test -p protocol --features typescript`, `cargo check -p protocol --target wasm32-unknown-unknown --no-default-features`, `deno task check`, `deno task build`, `cargo run -p yoi -- ticket doctor`, and `nix build .#yoi --no-link`。

既知の非ブロッキング事項:
- `ts-rs` は `#[serde(other)]` on `Segment::Unknown` に warning を出すが、generated artifact には `{ "kind": "unknown" }` が含まれ、current validation は pass。
- 一部 `Option<T>` + `skip_serializing_if` fields は TS で optional field ではなく required nullable に出る。将来 UI が該当 field を使う際は注意。
