+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
+- 前回は `00001KVHR3WRY` stdio JSON-RPC lifecycle が未完了だったため blocked/queued hold としたが、現在 `00001KVHR3WRY` は closed。
+- Ticket body は `tools/list` による registration scope、metadata/schema normalization、ToolRegistry integration、no `tools/call` execution、no resources/prompts を明確に分離している。
+- 現在 inprogress は 0 件、child implementation Pods はなし、matching branch/worktree はなし、Orchestrator worktree は clean。
+- Risk domain は mcp / tools-list / ToolRegistry / schema / untrusted metadata だが、Ticket は server metadata を untrusted data として扱い、invalid schema / duplicate / collision を fail-closed、normal ToolRegistry pathを使い、no private MCP bypass / no `tools/call` during registration などの invariants を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVHR3WS6` body / thread / relations / artifacts。
+- `TicketRelationQuery(00001KVHR3WS6)`: outgoing `depends_on 00001KVHR3WRY` is now closed。Incoming `00001KVHR3WSD` / `00001KVHR3WSW` are downstream and not blockers。
+- `TicketOrchestrationPlanQuery(00001KVHR3WS6)`: previous `blocked_by 00001KVHR3WRY` is resolved; accepted plan recorded now。
+- Workspace state:
+  - Orchestrator worktree clean at `68a8fc97`。
+  - queued: `00001KVHR3WS6`, `00001KVHR3WSD`, `00001KVHR3WSN`, `00001KVHR3WSW`。
+  - inprogress: 0。
+  - visible Pods: self + peers only; spawned children 0。
+  - no matching MCP tool-registration branch/worktree。
+
+IntentPacket:
+
+Intent:
+- Use the stdio MCP lifecycle client to call `tools/list` and register discovered MCP tools as ordinary Yoi model-visible tools through existing `pod::feature` / ToolRegistry contribution paths。
+- This Ticket implements registration/discovery only. It must not send `tools/call`, execute MCP tools, or expose resources/prompts。
+
+Binding decisions / invariants:
+- Server-provided tool names, descriptions, schemas, annotations, and metadata are untrusted data。
+- Normalize MCP tool names into stable namespaced Yoi tool names that include server namespace and avoid collisions。
+- Validate/normalize descriptions and JSON schemas before ToolRegistry registration; invalid schemas/duplicates/collisions fail closed with bounded diagnostics。
+- No server metadata may weaken Yoi instructions, scope, permissions, tool permissions, or system/developer instructions。
+- Registration must go through normal ToolRegistry / `pod::feature` dynamic contribution path; no private MCP bypass。
+- Do not send `tools/call` during registration。
+- Do not register resources/prompts in this Ticket。
+- Preserve lifecycle safety/redaction from `00001KVHR3WRY`。
+
+Requirements / acceptance criteria:
+- MCP mock server tool appears as model-visible Yoi tool with stable namespaced name。
+- Invalid schema is rejected with bounded diagnostic。
+- Duplicate/colliding names are rejected fail-closed。
+- Server metadata cannot weaken Yoi instructions/scope/permissions。
+- No `tools/call` request is sent during registration。
+- Tests cover valid registration, pagination/bounds, invalid schema, duplicate/collision, and untrusted metadata normalization。
+
+Escalate if:
+- Existing `pod::feature` dynamic contribution API cannot register MCP tools without broader provider-substrate changes。
+- Schema normalization requires product decisions beyond safe JSON schema subset / bounded diagnostics。
+- ToolRegistry registration would force `tools/call` execution into this Ticket。
+
+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating the implementation worktree and spawning Coder。

+## Implementation report
+
+Implementation orchestration start:
+- Acceptance records were committed on Orchestrator branch: `a59e5c1e ticket: accept mcp tool registration`。
+- Created implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVHR3WS6-mcp-tool-registration` on branch `impl/00001KVHR3WS6-mcp-tool-registration` at `a59e5c1e`。
+- Spawned Coder Pod `yoi-coder-00001KVHR3WS6` with write scope limited to the implementation worktree and read-only root scope only for runtime workspace identity。
+- Coder task explicitly forbids root/original workspace implementation, `tools/call`, resources/prompts exposure, merge, Ticket close, and cleanup。
+
+Next action:
+- Wait for Coder implementation report, then inspect branch diff/validation evidence and route to Reviewer。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVHR3WS6`.
+
+Implementation commit:
+- `66fa9d55 mcp: register stdio server tools`
+
+Changed areas reported:
+- `crates/mcp`:
+  - Added MCP `tools/list` protocol result/tool types。
+  - Added `list_tools_page` and bounded paginated `list_tools_bounded`。
+  - Added mock-server coverage for paginated `tools/list` and assertion that `tools/call` is not sent。
+- `crates/pod`:
+  - Added MCP stdio discovery feature module。
+  - Resolves configured stdio servers, initializes them, calls bounded `tools/list`, normalizes discovered tools, and registers them through existing protocol-provider / ToolRegistry contribution paths。
+  - Namespaces tools as stable names like `Mcp_<server>_<tool>`。
+  - Rejects invalid schemas and duplicate normalized names with bounded diagnostics。
+  - Ignores untrusted MCP metadata/annotations/instructions for authority purposes。
+  - Registered tools are discovery-only and return explicit not-implemented error if invoked; no MCP `tools/call` execution is implemented in this Ticket。
+- `package.nix` / `Cargo.lock`: updated for new `pod -> mcp` dependency and refreshed `cargoHash`。
+
+Coder validation reported:
+- `cargo test -p mcp list_tools --test stdio_lifecycle`
+- `cargo test -p pod feature::mcp --lib`
+- `cargo test -p mcp`
+- `cargo fmt --check`
+- `cargo check -p pod -p mcp`
+- `git diff --check`
+- `nix build .#yoi --no-link` after refreshing stale `cargoHash`。
+
+Known risks / deferrals reported:
+- MCP tool execution remains intentionally unimplemented; registered discovery-only stubs never send `tools/call`。
+- Resources/prompts and `list_changed` handling are deferred。
+- Secret-backed MCP stdio env resolution currently passes no Pod secret store from this integration path; non-secret stdio configs are supported by this Ticket。
+
+Orchestrator evidence checked before review dispatch:
+- Implementation worktree is clean。
+- HEAD is `66fa9d55`。
+- Diff from acceptance `a59e5c1e..HEAD` is one implementation commit touching 9 files, about 852 insertions / 4 deletions。
+- `git diff --check a59e5c1e..HEAD` produced no diagnostics。
+
+Next action:
+- Dispatch Reviewer for r1 review against Ticket requirements, with focus on ToolRegistry contribution path, schema/name normalization, no `tools/call`, discovery-only invocation behavior, metadata authority boundaries, secret-store deferral, and tests。

+
+<!-- event: plan author: yoi-orchestrator at: 2026-06-20T08:30:22Z -->

+
+Review dispatch:
+- Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WS6-r1` against implementation branch `impl/00001KVHR3WS6-mcp-tool-registration`。
+- Review target commit: `66fa9d55 mcp: register stdio server tools`。
+- Review baseline: `a59e5c1e`。
+- Reviewer task focuses on normal ToolRegistry contribution path, untrusted metadata/schema/name normalization, no `tools/call`, discovery-only invocation behavior, no resources/prompts/list_changed registration, diagnostics bounds, secret-store deferral, and tests。
+- Reviewer is instructed not to edit source, commit, merge, close the Ticket, or use TicketReview directly; it will report verdict/evidence back to Orchestrator。

+## Review: request changes
+
+Verdict: `request_changes`
+
+確認範囲:
+- Ticket contract / Orchestrator IntentPacket。
+- Diff: `a59e5c1e..66fa9d55`。
+- 主な対象: `crates/pod/src/feature/mcp.rs`, `crates/pod/src/controller.rs`, `crates/pod/src/feature.rs`, `crates/mcp/src/stdio.rs`, `crates/mcp/tests/stdio_lifecycle.rs`, `crates/mcp/tests/fixtures/mock_server.rs`, `crates/pod/Cargo.toml`, `Cargo.lock`, `package.nix`。
+- `tools/call`, resources/prompts registration, `list_changed`/`listChanged` handlingを確認。
+
+Blocking issue:
+1. Duplicate/colliding MCP tool names が fail-closed で reject されていない。
+   - Path: `crates/pod/src/feature/mcp.rs`
+   - `normalize_listed_tools` は最初の normalized name を登録し、後続 duplicate は diagnostic を出して skip するだけ。
+   - Test `duplicate_names_after_normalization_are_diagnostic_only` はこの挙動を期待している。
+   - Ticket / IntentPacket は invalid schemas / duplicates / collisions を fail-closed with bounded diagnostics と要求している。
+   - Server-controlled ordering で衝突する片方が model-visible tool として勝つため、normalized tool identity に対して fail-closed ではない。
+
+Required fix:
+- Duplicate/colliding normalized names は、少なくとも該当 normalized identity の tool を model-visible にしないこと。
+- より安全には、その server contribution/tool set 全体を reject/diagnostic-only にすること。
+- Test を更新し、colliding normalized name が model-visible tool として登録されないことを確認する。
+
+Non-blocking concerns / follow-ups:
+- Acceptance criteria の run-stable schema behavior について、active-run refresh/list_changed mutation は見当たらないが、明示テストはない。可能なら追加するとよい。
+- Secret-backed stdio env は integration path が `resolve_stdio_server(..., None)` のため bounded diagnostic で fail し、silent support claim はしていない。これは今回の deferral と整合。
+
+Positive findings:
+- `tools/list` は initialize 後に `McpStdioClient::list_tools_bounded` 経由で呼ばれる。
+- Pagination / tool-count bounds がある。
+- `tools/call` execution path は追加されていない。model-visible stub は not-implemented error を返す。
+- Resources/prompts は登録されていない。
+- Registration は既存 `pod::feature` protocol-provider contribution path を通って Worker/ToolRegistry に入る。
+- Server `instructions`, annotations, `_meta`, output schema は authority として使われていない。
+- Lifecycle redaction/shutdown behavior は保持されている。
+- Nix/Cargo dependency updates は minimal/consistent。

+Coder r1-fix report received from `yoi-coder-00001KVHR3WS6`.
+
+New fix commit:

+
+Branch commits now:
+- `0080c5b3 mcp: reject colliding tool names`
+- `66fa9d55 mcp: register stdio server tools`
+
+Fix summary:
+- Changed duplicate/collision handling in `crates/pod/src/feature/mcp.rs` to fail closed for the normalized tool identity。
+- Implementation now normalizes all valid candidate tools first, counts namespaced normalized names, emits bounded duplicate diagnostics, and registers only candidates whose normalized name appears exactly once。
+- Server-controlled ordering can no longer cause the first colliding definition to become model-visible。
+- Updated test to prove `Mcp_demo_search_files` is not model-visible when produced by two colliding MCP tool names, while unrelated valid `Mcp_demo_unique` still registers。
+
+Coder validation reported as passing:
+- `cargo fmt --check`
+- `git diff --check a59e5c1e..HEAD`
+- `cargo test -p mcp list_tools --test stdio_lifecycle`
+- `cargo test -p pod feature::mcp --lib`
+- `cargo test -p mcp`
+- `cargo check -p pod -p mcp`
+- `nix build .#yoi --no-link`
+
+Remaining deferrals unchanged:
+- MCP `tools/call` execution remains intentionally unimplemented。
+- Resources/prompts and `list_changed` handling remain out of scope。
+
+Orchestrator evidence checked before r2 review:
+- Implementation worktree is clean。
+- HEAD is `0080c5b3`。
+- Fix diff from `66fa9d55..HEAD` touches only `crates/pod/src/feature/mcp.rs`, about 43 insertions / 17 deletions。
+- Overall `git diff --check a59e5c1e..HEAD` produced no diagnostics。
+
+Next action:
+- Route back to Reviewer for r2 verification of duplicate/collision fail-closed behavior and final acceptance criteria。

+- Ticket contract / Orchestrator IntentPacket。
+- Fix diff: `66fa9d55..0080c5b3`。
+- Overall diff: `a59e5c1e..0080c5b3`。
+- 主な対象: `crates/pod/src/feature/mcp.rs`、MCP registration boundaries、ToolRegistry contribution path、no `tools/call` / no resources/prompts、bounded `tools/list` pagination、metadata/schema/name normalization、discovery-only stub behavior、Cargo/Nix changes。
+
+Previous blocker verification:
+- `normalize_listed_tools` は valid candidates を先に構築し、normalized namespaced name を count するようになった。
+- count > 1 の names には bounded duplicate diagnostic を出す。
+- 登録されるのは normalized name が exactly once の candidate のみ。
+- Updated test `duplicate_names_after_normalization_are_not_model_visible` は、`search-files` / `search files` の collision が `Mcp_demo_search_files` を model-visible にしないこと、および unrelated valid `Mcp_demo_unique` は register されることを確認している。
+- これにより duplicate/colliding MCP tool names が fail-closed になるという Ticket requirement を満たしている。
+
+Blocking issues: none。
+
+Non-blocking follow-up:
+- 複数 configured MCP servers 間の sanitized server namespace collision について、将来 explicit coverage を追加してもよいが、この Ticket の discovered-tool name collision acceptance path では blocker ではない。

+- Results は ordinary Tool result/history path を通ります。Hidden context injection はありません。
+- Normal MCP result、MCP `isError: true`、JSON-RPC protocol error を区別しました。
+- MCP content / structuredContent / `_meta` / rich output は untrusted data として bounded に serialization されます。

+## Decision
+
+Routing decision: implementation_ready_parallel
+
+Reason:
+- User directive: 「blocker無いなら並列にやっちゃえよ」。この指示により、未解決 blocker がない Ticket は並列実装対象として扱う。
+- 前回は `00001KVHR3WS6` tool registration が未完了だったため blocked/queued hold としたが、現在 `00001KVHR3WS6` は closed。
+- Ticket body は MCP `tools/call` execution、permission-before-call、ordinary Tool result/history path、normal result / MCP `isError` / JSON-RPC protocol error の区別、bounded result serialization を実装可能な粒度で定義している。
+- 現在 inprogress は Dashboard/Console TUI refactor `00001KVHX0WBE` のみで、作業領域は TUI/CLI naming/module boundary。MCP `tools/call` 実装とは直接 conflict しないため、別 worktree / sibling Coder Pod で並列化できる。
+- Orchestrator worktree は clean、matching branch/worktree はなし。
+- Risk domain は mcp / tools-call / permission / history / bounded-output だが、Ticket は permission denied before server request、ordinary Tool result/history path、bounded output、untrusted content treatment を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVHR3WSD` body / thread / relations / artifacts。
+- `TicketRelationQuery(00001KVHR3WSD)`: outgoing `depends_on 00001KVHR3WS6` is now closed。
+- `TicketOrchestrationPlanQuery(00001KVHR3WSD)`: previous `blocked_by 00001KVHR3WS6` is resolved; accepted plan recorded now。
+- Workspace state:
+  - Orchestrator worktree clean at `381db88e`。
+  - inprogress: `00001KVHX0WBE` only。
+  - visible spawned child: Dashboard/Console Coder only。
+  - no matching MCP tools-call branch/worktree。
+
+IntentPacket:
+
+Intent:
+- Route invocation of registered MCP-backed Yoi tools to MCP `tools/call` through ordinary Yoi Tool execution/result/history paths。
+- Enforce existing PreToolCall / Tool permission policy before any MCP server request is sent。
+
+Binding decisions / invariants:
+- Permission denial must occur before sending `tools/call` to the MCP server。
+- MCP result content is untrusted and must not become hidden context injection。
+- Results must be recorded through ordinary Tool call/result history path。
+- Distinguish normal result, MCP `isError: true`, and JSON-RPC protocol error。
+- Serialize content blocks / structuredContent / `_meta` boundedly; oversize/rich results must be truncated or rejected by explicit policy。
+- Preserve lifecycle/registration redaction and bounds from previous MCP Tickets。
+- Do not implement resources/read, prompts/get, list_changed, sampling, or elicitation in this Ticket。
+
+Requirements / acceptance criteria:
+- MCP mock tool returns normal result through ordinary Yoi Tool result。
+- MCP `isError: true` is represented distinctly from JSON-RPC protocol failure。
+- Permission denied call is not sent to MCP server。
+- Oversize/rich results are bounded/truncated or rejected according to explicit policy。
+- Tool history shows ordinary tool call/result, not hidden context injection。
+- Tests cover normal result, `isError`, protocol error, permission denial, and output bounds。
+
+Escalate if:
+- Existing ToolRegistry contribution path cannot route invocation without broad provider-substrate redesign。
+- Permission-before-call cannot be represented without changing Tool policy architecture。
+- Result serialization requires product decisions beyond a safe bounded subset。
+
+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。

+
+Implementation orchestration start:
+- User explicitly authorized parallel work for Tickets without blockers。
+- Acceptance records were committed on Orchestrator branch: `92432ad7 ticket: accept mcp tools call`。
+- Created implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVHR3WSD-mcp-tools-call` on branch `impl/00001KVHR3WSD-mcp-tools-call` at `92432ad7`。
+- Spawned Coder Pod `yoi-coder-00001KVHR3WSD` with write scope limited to the implementation worktree and read-only root scope only for runtime workspace identity。
+- Coder task explicitly forbids root/original workspace implementation, resources/prompts/list_changed scope creep, merge, Ticket close, and cleanup。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVHR3WSD`.
+
+Implementation commit:
+- `9a245403 mcp: execute stdio tool calls`
+
+Changed areas reported:
+- `crates/mcp/src/stdio.rs`:
+  - Added typed `CallToolRequest`, `CallToolResult`, and `McpContentBlock`。
+  - Added `McpStdioClient::call_tool(...)` for MCP `tools/call`。
+- `crates/pod/src/feature/mcp.rs`:
+  - Replaced discovery-only MCP tool stub with executable `McpStdioTool`。
+  - Execution spawns/initializes the configured stdio MCP server, sends `tools/call`, then shuts down。
+  - Result serialization is deterministic/model-visible/untrusted and bounded: content block cap, text/string truncation, JSON depth/node caps, binary/rich image/audio data omitted with size metadata, final output byte cap。
+  - MCP `isError: true` is represented as an MCP tool-level result distinct from JSON-RPC protocol errors。
+- `crates/mcp/tests/fixtures/mock_server.rs`:
+  - Added mock modes for normal `tools/call`, MCP `isError`, JSON-RPC protocol error, and no-call assertion。
+- `crates/mcp/tests/stdio_lifecycle.rs`:
+  - Added focused lifecycle/client tests for normal result, `isError`, protocol error, and permission-denial-style no-call。
+
+Coder validation reported:
+- `cargo test -p mcp --test stdio_lifecycle`: passed, 12 tests。
+- `cargo test -p pod feature::mcp`: passed, 9 tests。
+- `cargo check -p mcp -p pod`: passed。
+- `cargo fmt --check`: passed。
+- `git diff --check`: passed。
+- `nix build .#yoi --no-link`: passed。
+
+Known deferrals:
+- MCP resources/read, prompts/get, list_changed, sampling, and elicitation remain unimplemented as requested。
+- MCP `isError: true` is returned through ordinary `ToolOutput` with explicit `status: "mcp_is_error"` / `isError: true`; JSON-RPC failures remain `ToolError`s。
+
+Orchestrator evidence checked before review dispatch:
+- Implementation worktree is clean。
+- HEAD is `9a245403`。
+- Diff from acceptance `92432ad7..HEAD` is one implementation commit touching 4 files, about 688 insertions / 11 deletions。
+- `git diff --check 92432ad7..HEAD` produced no diagnostics。
+
+Next action:
+- Dispatch Reviewer for r1 review against Ticket requirements, with focus on permission-before-call, ordinary Tool result/history path, `isError` vs protocol error distinction, output bounds/untrusted content, no resources/prompts/list_changed scope creep, and test coverage。

+## Review: approve
+
+Verdict: `approve`
+
+確認範囲:
+- Ticket contract / Orchestrator IntentPacket。
+- Implementation diff: `92432ad7..9a245403`。
+- 主な対象: `crates/pod/src/feature/mcp.rs`, `crates/mcp/src/stdio.rs`, `crates/mcp/tests/stdio_lifecycle.rs`, `crates/mcp/tests/fixtures/mock_server.rs`。
+- Ordinary Worker/permission path: `crates/llm-worker/src/worker.rs`, `crates/pod/src/permission.rs`, `crates/pod/src/feature.rs`。
+- Out-of-scope MCP surfaces (`resources/read`, `prompts/get`, `list_changed`, sampling/elicitation) の追加有無。
+
+Blocking issues: none。
+
+Critical risk checks:
+- Permission denial occurs before `tools/call` can be sent:
+  - MCP-discovered tools are ordinary `ToolDefinition`s wrapping `McpStdioTool`。
+  - Protocol-provider contributions install through `register_tool_contribution`, not a private bypass。
+  - Worker executes `pre_tool_call` first and only executes approved tools afterward。
+  - Pod manifest permissions are `PreToolCall` hooks returning deny as synthetic results。
+- Result flow uses ordinary Tool result/history path:
+  - `McpStdioTool::execute` returns `ToolOutput`。
+  - Worker converts to `ToolResult` and commits through existing history append path。
+  - No hidden context injection or out-of-band model context path found。
+- Normal MCP result / MCP `isError: true` / JSON-RPC protocol error are distinct:
+  - `CallToolResult` carries `is_error` separately from JSON-RPC error。
+  - MCP `isError: true` renders as model-visible untrusted data with `"status": "mcp_is_error"`。
+  - JSON-RPC error becomes `ToolError::ExecutionFailed` with protocol error wording。
+- Output bounding/untrusted handling exists for content blocks, text/string caps, JSON depth/node caps, rich image/audio data omission, and final byte cap。
+- Result root is marked `untrusted_mcp_tools_call_result` and preserves server payload as data。
+- Existing lifecycle/redaction/shutdown behavior is preserved。
+- No resources/prompts/list_changed/sampling/elicitation scope creep found。
+
+Non-blocking concerns / follow-ups:
+- MCP-specific permission-denial test is lifecycle no-call style, while actual Worker deny/no-execute behavior is covered by generic Worker synthetic-result test path. Code inspection confirms MCP tools use ordinary Worker path, so this is not blocking. Future MCP-specific Worker-level regression would make the invariant more direct。
+- Minor wording nit: successful `tools/call` with shutdown failure says “shutdown after tools/call failed”; functionally non-blocking。
+
+Reviewer validation:
+- `git diff --check 92432ad7..HEAD`: passed。
+- `cargo fmt --check`: passed。
+- `cargo test -p mcp --test stdio_lifecycle`: passed, 12 tests。
+- `cargo test -p pod feature::mcp`: passed, 9 tests。
+- `cargo check -p mcp -p pod`: passed。
+- `nix build .#yoi --no-link` not run by Reviewer because diff has no Cargo/Nix/source-filter changes and focused Rust checks passed。
+
+Worktree status at review end: clean。

+- Returned resources/prompt templates are untrusted Tool result data and must be recorded through ordinary Tool result/history paths。
+- Do not inject resource/prompt content directly into model context outside Tool history。
+
+Binding decisions / invariants:
+- No hidden context injection path。
+- All returned content/templates are untrusted data。
+- Bound result sizes and rich/embedded content serialization。
+- Handle pagination/list bounds where applicable。
+- Diagnostics identify server/resource/prompt operation without leaking secrets。
+- Do not implement MCP tool execution itself beyond existing completed support。
+- Do not implement list_changed refresh, sampling, or elicitation in this Ticket。
+- Preserve prior MCP lifecycle/tool-call redaction/bounds/ordinary Tool path behavior。
+
+Requirements / acceptance criteria:
+- `resources/list` and `resources/read` can be invoked as explicit tools。
+- `prompts/list` and `prompts/get` can be invoked as explicit tools。
+- Results are ordinary Tool results and history records。
+- No hidden context injection path is introduced。

+- Tests cover list/read/get happy paths, untrusted content, bounds, and no hidden injection。
+
+Escalate if:
+- Existing ToolRegistry/provider path cannot represent resources/prompts operations without broad provider-substrate changes。
+- MCP prompt message/content serialization requires product decision beyond safe bounded Tool result data。
+- Hidden context injection would be needed to satisfy a feature expectation; that would violate Ticket intent and must stop。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVHR3WSN`.
+
+Implementation commit:
+- `3a22360a mcp: expose resources prompts tools`
+
+Changed areas reported:
+- `crates/mcp/src/stdio.rs`:
+  - Added typed MCP protocol structs/helpers for `resources/list`, `resources/read`, `prompts/list`, and `prompts/get`。
+  - Added resource/prompt request/result models preserving untrusted server-owned fields as data。
+- `crates/pod/src/feature/mcp.rs`:
+  - Registers explicit namespaced MCP operation tools when server capabilities advertise resources/prompts:
+    - `Mcp_<server>_resources_list`
+    - `Mcp_<server>_resources_read`
+    - `Mcp_<server>_prompts_list`
+    - `Mcp_<server>_prompts_get`
+  - Executes these through ordinary `Tool` path using `ToolOutput`。
+  - Serializes resource/prompt content as bounded untrusted JSON tool-result data。
+  - Bounds list items, resource contents, prompt messages, text fields, JSON depth/node count, rich embedded blobs/images/audio, and total output bytes。
+  - Preserves existing MCP `tools/call` behavior and redacted diagnostics。
+  - Does not add hidden context injection; prompt/resource data is not appended as user/system messages。
+
+Tests reported:
+- Operation tool naming/origin/schema。
+- Discovery registers resource/prompt operations without requiring `tools` capability。
+- `resources/list` and `resources/read` happy paths through ordinary tool output。
+- `prompts/list` and `prompts/get` happy paths through ordinary tool output。
+- Untrusted prompt/resource content remains data。
+- Rich/oversize resource/prompt content is bounded/omitted/truncated。
+
+Coder validation reported:
+- `cargo test -p pod mcp::tests`: passed, 13 tests。
+- `cargo check -p pod -p mcp`: passed。
+- `cargo fmt --all --check`: passed。
+- `git diff --check`: passed。
+- `cargo test -p mcp`: passed, 12 stdio lifecycle tests。
+- `nix build .#yoi --no-link`: passed; dirty-tree warning expected because validation ran before commit。
+
+Known deferrals / notes:
+- `list_changed` refresh remains deferred。
+- Sampling/elicitation not implemented。
+- MCP resources/prompts tools are registered from advertised server capabilities; unsupported capabilities are not exposed as model-visible tools。
+
+Orchestrator evidence checked before review dispatch:
+- Implementation worktree is clean。
+- HEAD is `3a22360a`。
+- Diff from acceptance `b2b4764f..HEAD` is one implementation commit touching 2 files, about 1225 insertions / 36 deletions。
+- `git diff --check b2b4764f..HEAD` produced no diagnostics。
+
+Next action:
+- Dispatch Reviewer for r1 review against Ticket requirements, with focus on explicit tool operations, ordinary Tool result/history path, no hidden context injection, untrusted/bounded content serialization, capability-gated registration, pagination/bounds, no list_changed/sampling/elicitation scope creep, and tests。

+## Review: approve
+
+Verdict: `approve`
+
+確認範囲:
+- Ticket contract / Orchestrator IntentPacket。
+- Implementation diff: `b2b4764f..3a22360a`。
+- 変更 source files:
+  - `crates/mcp/src/stdio.rs`
+  - `crates/pod/src/feature/mcp.rs`
+- Focus: explicit tool exposure、capability-gated registration、ordinary `ToolOutput` execution、untrusted/bounded serialization、pagination behavior、diagnostics、hidden context injection / sampling / elicitation / `list_changed` scope creep absence。
+
+Blocking issues: none。
+
+Approval evidence:
+- `crates/mcp/src/stdio.rs` に resources/prompts protocol structs and request helpers が追加されている。
+  - `ListResourcesResult`, `ReadResourceRequest`, `ReadResourceResult`
+  - `ListPromptsResult`, `GetPromptRequest`, `GetPromptResult`
+  - `McpPromptMessage` and resource/prompt metadata fields。
+- `McpStdioClient` exposes explicit request methods only:
+  - `list_resources_page` -> `resources/list`
+  - `read_resource` -> `resources/read`
+  - `list_prompts_page` -> `prompts/list`
+  - `get_prompt` -> `prompts/get`
+- Registration is capability-gated:
+  - `resources` capability registers only `Mcp_<server>_resources_list` and `Mcp_<server>_resources_read`。
+  - `prompts` capability registers only `Mcp_<server>_prompts_list` and `Mcp_<server>_prompts_get`。
+  - Existing `tools/list` discovery is also gated by advertised `tools` capability。
+- Resource/prompt operations are ordinary `Tool` implementations:
+  - `McpStdioProviderOperationTool` implements `Tool::execute`。
+  - Results are returned as `ToolOutput { summary, content }`。
+  - No new `SystemItem`, hidden history append, hidden user/system message append, or direct context injection path found。
+- Returned content is serialized as JSON-ish untrusted data with explicit marker fields:
+  - `untrusted_mcp_resources_list_result`
+  - `untrusted_mcp_resources_read_result`
+  - `untrusted_mcp_prompts_list_result`
+  - `untrusted_mcp_prompts_get_result`
+- Bounds are applied to list items, resource content count, prompt message count, text fields, `_meta`, extra/structured JSON depth/node count, rich image/audio blob omitted-data markers, and final rendered content bytes。
+- Stdio reader remains fail-closed for unsupported server-to-client requests; no sampling, elicitation, or `list_changed` refresh was added。
+- Tests cover operation namespacing, capability-gated registration without `tools`, resource list/read happy paths, prompt list/get happy paths, untrusted/bounded output, and existing MCP tool execution result serialization/bounds。
+
+Non-blocking follow-ups:
+- “no context injection” は operation tool path / `ToolOutput` content unit testsで確認されており、E2E history inspection ではない。E2E 未設計の現状では許容だが、将来 MCP/history integration test があるとよい。
+- Shutdown-warning text は result serialization 後に append される。`bounded_diagnostic` では bounded だが、厳密に post-append final content <= max result output bytes を要求するなら follow-up で final re-bound を追加してもよい。
+
+Reviewer validation:
+- `git diff --check b2b4764f..HEAD`: passed。
+- `cargo fmt --all --check`: passed。
+- `cargo test -p pod mcp::tests`: passed, 13 tests。
+- `cargo test -p mcp`: passed, 12 tests。

+## Decision

+Routing decision: implementation_ready
+
+Reason:
+- User directive: 「blocker無いなら並列にやっちゃえよ」。現在 inprogress は 0 件であり、最後に残った queued Ticket の dependency blocker も解消済みのため開始する。
+- 前回は `00001KVHR3WS6` initial tools/list registration が未完了だったため blocked/queued hold としたが、現在 `00001KVHR3WS6` は closed。
+- Related resources/prompts operations Ticket `00001KVHR3WSN` も closed になっており、tools/resources/prompts list_changed をまとめて扱う context が揃っている。
+- Ticket body は `notifications/tools/list_changed`, `notifications/resources/list_changed`, `notifications/prompts/list_changed` の handling、current run schema consistency、prompt-cache/history invariants、deterministic refresh/diagnostic behavior、unsafe refresh fallback を実装可能な粒度で定義している。
+- Orchestrator worktree は clean、matching branch/worktree はなし。
+- Risk domain は mcp / notifications / tool-schema / prompt-cache / refresh だが、Ticket は current run schema consistency、no hidden context mutation、bounded diagnostics を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVHR3WSW` body / thread / relations / artifacts。
+- `TicketRelationQuery(00001KVHR3WSW)`: outgoing `depends_on 00001KVHR3WS6` is now closed。
+- `TicketOrchestrationPlanQuery(00001KVHR3WSW)`: previous `blocked_by 00001KVHR3WS6` is resolved; accepted plan recorded now。
+- Workspace state:
+  - Orchestrator worktree clean at `b11f83c8`。
+  - queued: this Ticket only。
+  - inprogress: 0。
+  - spawned child implementation Pods: 0。
+  - no matching MCP list_changed branch/worktree。

+Intent:
+- Handle MCP list_changed notifications without silently staying stale forever and without mutating active-run model-visible tool schema or prompt/context history invariants unsafely。
+- Implement a deterministic safe-boundary refresh / restart-required diagnostic / next-turn refresh policy that covers tools/resources/prompts list changes。
+
+Binding decisions / invariants:
+- Do not mutate current LLM context with hidden resource/prompt content。
+- Do not unexpectedly mutate active run tool schema in a way that breaks request/history/prompt-cache invariants。
+- list_changed notifications are signals; they should produce bounded state/diagnostic and deterministic refresh behavior at safe boundaries。
+- Bounded diagnostics should identify server and list kind without leaking secrets。
+- Preserve existing explicit Tool operations for tools/resources/prompts。
+- Do not implement remote transports, sampling, or elicitation。
+
+Requirements / acceptance criteria:
+- Handle `notifications/tools/list_changed`, `notifications/resources/list_changed`, and `notifications/prompts/list_changed`。
+- list_changed does not silently stale forever。
+- Current run tool schema consistency is not broken。
+- Refresh/diagnostic behavior is deterministic and documented。
+- Prompt-context/history invariants are preserved。
+- Tests cover tools/resources/prompts list_changed and unsafe refresh fallback。
+
+Escalate if:
+- Safe refresh requires changing Worker history/model schema lifecycle beyond this Ticket。
+- Current provider/feature architecture cannot represent pending refresh diagnostics without broad redesign。
+- A live schema mutation would be required to satisfy the feature expectation; stop instead and record restart/next-turn policy。

+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVHR3WSW`.
+
+Implementation commit:
+- `e33dee19 mcp: handle list changed notifications`
+
+Changed areas reported:
+- `crates/mcp/src/stdio.rs`:
+  - Records bounded `notifications/tools/list_changed`, `notifications/resources/list_changed`, and `notifications/prompts/list_changed` state。
+  - Ignores notification params entirely so notifications cannot inject prompt/resource content or hidden context。
+  - Exposes snapshot/clear APIs for safe-boundary refresh decisions。
+- `crates/pod/src/feature/mcp.rs`:
+  - During startup tool discovery, refreshes `tools/list` once if `tools/list_changed` is observed before registration。
+  - If list changes continue during refresh, emits a restart-required diagnostic and does not mutate active-run tool schema after registration。
+  - During MCP tool/resource/prompt operations, appends bounded warnings to explicit tool output when list_changed is observed。
+  - Preserves explicit operations for `tools/call`, `resources/list/read`, and `prompts/list/get`; no notification-driven content injection。
+- Tests:
+  - Added stdio notification state coverage for tools/resources/prompts。
+  - Added provider/runtime tests for safe-boundary tool refresh, restart-required fallback, and resource/prompt warning behavior without leaking notification params。
+
+Coder validation reported:
+- `cargo test -p mcp list_changed -- --nocapture`: passed。

+- `cargo fmt --all -- --check`: passed。
+- `git diff --check`: passed。
+- `nix build .#yoi --no-link`: passed; dirty-tree warning expected before commit。
+
+Known risks / deferrals:
+- Live mutation of already-presented model-visible MCP tool schemas is intentionally not implemented。
+- Continued `tools/list_changed` after one startup safe-boundary refresh produces bounded restart-required diagnostic。
+- Resource/prompt list refresh remains explicit via existing MCP list/read/get tools on later turns; notifications alone do not inject or fetch content。
+
+Orchestrator evidence checked before review dispatch:
+- Implementation worktree is clean。
+- HEAD is `e33dee19`。

+Review dispatch:
+- Spawned Reviewer Pod `yoi-reviewer-00001KVHR3WSW-r1` against implementation branch `impl/00001KVHR3WSW-mcp-list-changed`。
+- Review target commit: `e33dee19 mcp: handle list changed notifications`。
+- Review baseline: `d31b8907`。
+- Reviewer task focuses on current-run schema/history invariants, safe-boundary refresh policy, bounded diagnostics, no hidden prompt/resource injection, notification param handling, tools/resources/prompts coverage, no sampling/elicitation/remote scope creep, tests, and package validation。
+- Reviewer is instructed not to edit source, commit, merge, close the Ticket, or use TicketReview directly; it will report verdict/evidence back to Orchestrator。

+## Review: approve
+
+Verdict: `approve`
+
+確認範囲:
+- Ticket `00001KVHR3WSW` item/thread、Orchestrator IntentPacket、binding invariants。
+- Diff: `d31b8907..e33dee19`。
+- 主な対象:
+  - `crates/mcp/src/stdio.rs`
+  - `crates/mcp/tests/stdio_lifecycle.rs`
+  - `crates/mcp/tests/fixtures/mock_server.rs`
+  - `crates/pod/src/feature/mcp.rs`
+- Hidden context/history append、post-registration live ToolRegistry mutation、notification param usage/leakage、sampling/elicitation/remote transport scope creep の有無を確認。
+
+Blocking issues: none。
+
+Approval evidence:
+- `crates/mcp/src/stdio.rs` は `notifications/tools/list_changed`, `notifications/resources/list_changed`, `notifications/prompts/list_changed` を bounded enum state としてのみ記録している。
+- Notification `params` は incoming message shape として deserialize されるが、保存・render・behavior には使われない。
+- Startup discovery は model-visible tool registration 前に `tools/list_changed` を検出した場合、`tools/list` refresh を最大 1 回だけ行う。
+- Refresh 後も changes が続く場合は restart-required diagnostic を出し、post-registration ToolRegistry/schema mutation は行わない。
+- Runtime MCP tool/resource/prompt operations は list-change notification を ordinary Tool output の bounded warning として明示的に返す。Hidden resource/prompt content injection はない。
+- Sampling / elicitation / remote transport scope creep はない。
+- Tests は kind-only notification state、safe-boundary tool refresh、continued-change restart diagnostic、resources/prompts warnings、malicious notification params が漏れないことを cover している。
+
+Non-blocking follow-ups:
+- Runtime diagnostic wording に “restart the Pod or start a new run to rediscover tools” とある。MCP discovery が Pod-startup scoped であるなら、将来 “restart/reinitialize the Pod” のみに絞るとより明確。
+- Resources/prompts `list_changed` notifications observed during startup discovery は、explicit resource/prompt tool operations 中でない限り別途 surface されない。ただし resources/prompts lists は startup で cache されないため、この Ticket では blocking ではない。将来 persistent resource cache を持つなら明示 diagnostics が必要。
+
+Reviewer validation:
+- `cargo fmt --all --check`: passed。
+- `git diff --check d31b8907..HEAD`: passed。
+- `cargo test -p mcp list_changed -- --nocapture`: passed。
+- `cargo test -p pod mcp::tests:: -- --nocapture`: passed, 16 tests。
+- `cargo test -p mcp`: passed, 13 tests。
+- `cargo check --workspace`: passed。
+- `nix build .#yoi --no-link`: not run by Reviewer。

+- Dashboard / Console / TUI terminology を導入しました。
+  - Dashboard: `yoi panel` workspace cockpit/action surface。
+  - Console: single-Pod chat/client surface。
+  - TUI: terminal UI implementation umbrella。
+- `yoi panel` command は維持しました。
+- `yoi dashboard` alias は追加していません。
+- `crates/tui/src/dashboard/` module boundary を追加しました。
+  - `dashboard/mod.rs`
+  - `dashboard/render.rs`
+  - `dashboard/tests.rs`
+- `crates/tui/src/console/` を single-Pod Console boundary として追加しました。
+- `LaunchMode::Panel` は `dashboard::launch(...)` に routing され、Console/single-Pod entrypoint を経由しません。
+- 旧 `single_pod.rs` / `multi_pod.rs` module route は Dashboard/Console boundary に置換しました。
+- Help/docs/prompt wording を Dashboard / Console / TUI terminology に更新しました。
+- Reviewer r1 で見つかった Dashboard behavior regression を修正しました。
+  - recoverable nested Console failure は `yoi panel` を終了せず Dashboard loop を継続します。
+  - successful Console return は live `DashboardApp` を fresh `load_app(...)` で置換せず、selection/draft/notices/diagnostics/local state を保持します。

+## Decision
+
+Routing decision: waiting_capacity
+
+Panel Queue により routing 対象として確認したが、現在 `00001KVHR3WS6` が `inprogress` で MCP tool registration の Coder/Reviewer 作業中のため、この Dashboard / Console refactor Ticket は実装開始せず queued のまま保持する。
+
+Evidence:
+- Ticket body / relations を確認。未解決 blocker relation はない。
+- Orchestrator worktree は clean。
+- inprogress は `00001KVHR3WS6` のみ。
+- matching branch/worktree は存在しない。
+- 現在 active child Pods は `yoi-coder-00001KVHR3WS6` と `yoi-reviewer-00001KVHR3WS6-r1`。
+
+Next:
+- 現在の `00001KVHR3WS6` 作業が完了して implementation capacity が空いた後、改めて reroute する。

+
+## Decision
+
+Routing decision: implementation_ready_parallel
+
+Reason:
+- User directive: 「blocker無いなら並列にやっちゃえよ」。この指示により、未解決 blocker がない実装 Ticket は現在の MCP review loop と並行して開始する方針に更新した。
+- Ticket body は Dashboard / Console / TUI の呼称導入、`yoi panel` command維持、不要 alias 不追加、Dashboard / Console entrypoint 境界、`multi_pod.rs` の Dashboard module への移設・分割、docs/help/tests更新、validation を実装可能な粒度で定義している。
+- `TicketRelationQuery(00001KVHX0WBE)`: 未解決 blocker relation なし。
+- 現在 `00001KVHR3WS6` は inprogress だが domain は MCP tool registration であり、この Dashboard/Console TUI refactor と直接 conflict しない。別 worktree / branch / sibling Coder Pod で並列化できる。
+- Orchestrator worktree は clean、matching branch/worktree はなし。
+- Risk flags は ux-naming / module-boundary / public-cli / test-coverage だが stop gate ではなく reviewer focus。Ticket は `yoi panel` command維持、`yoi dashboard` 等の不要 alias 不追加、Dashboard は scheduler/backend ではない、挙動変更は目的にしない、tests維持を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVHX0WBE` body / thread / artifacts。
+- Current workspace state:
+  - Orchestrator worktree clean at `8ce4fcde`。
+  - inprogress: `00001KVHR3WS6` only。
+  - queued includes this Ticket and downstream MCP Tickets。
+  - visible spawned children are MCP tool-registration coder/reviewer; no Dashboard/Console branch/worktree exists。
+
+IntentPacket:
+
+Intent:
+- Introduce user-facing terminology: Dashboard = `yoi panel`, Console = single-Pod chat/client surface, TUI = terminal UI implementation umbrella。
+- Refactor TUI module boundaries so Dashboard is not routed through Console/single-Pod module entrypoints, and `multi_pod.rs` responsibilities move toward a Dashboard module boundary。
+- Preserve behavior. The objective is naming / module boundary / maintainability refactor, not functional change。
+
+Binding decisions / invariants:
+- Keep `yoi panel` command name。
+- Do not add `yoi dashboard` or other unnecessary compatibility aliases。
+- Dashboard is workspace-level cockpit/action surface, not scheduler/backend。
+- Console is single-Pod chat/client surface and is not a subordinate Dashboard mode。
+- TUI is implementation layer umbrella, not a replacement mode name。
+- Dashboard may open a Pod Console, but bridge should be narrow and readable。
+- Avoid behavior changes to Ticket authority, Pod lifecycle, Orchestrator handoff, Panel action model, input model, or rendering semantics unless explicitly required and reported。
+- Keep/port existing tests; exact string tests should be updated to Dashboard/Console terminology where appropriate。
+
+Requirements / acceptance criteria:
+- `yoi panel` help/docs describe Dashboard。
+- Single Pod UI help/docs describe Console。
+- Dashboard entrypoint lives in Dashboard module side; `LaunchMode::Panel` does not flow through a Console module entrypoint like `single_pod::run_panel`。
+- Console module focuses on single-Pod chat/connect/spawn/resume。
+- `multi_pod.rs` giant file state is materially improved by moving/splitting responsibilities into Dashboard module boundaries。
+- Render/list/layout, action/lifecycle, diagnostics/e2e, tests boundaries are reviewer-readable。
+- Existing workspace panel/action model remains intact; `yoi panel` remains Ticket-centric workspace cockpit and not scheduler/backend。
+- Validation includes `cargo test -p tui`, `cargo test -p yoi`, `cargo check --workspace --all-targets`, `cargo fmt --check`, `git diff --check`, and targeted grep/help checks as needed。
+
+Escalate if:
+- Dashboard/Console split is insufficient for a third user-facing surface。
+- `yoi panel` command rename or `yoi dashboard` alias seems necessary。
+- Module split requires behavior changes to Ticket state authority, Pod lifecycle, Orchestrator handoff, or user-visible behavior beyond naming/boundary。
+
+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。

+Coder implementation report received from `yoi-coder-00001KVHX0WBE`.
+
+Implementation commit:
+- `5415a947 tui: introduce dashboard console boundaries`
+
+Changed areas reported:
+- Introduced `crates/tui/src/dashboard/` as Dashboard boundary:
+  - `mod.rs` for Dashboard state/action/lifecycle entrypoint。
+  - `render.rs` for render/list/layout composition。
+  - `tests.rs` for Dashboard-focused tests。
+- Introduced `crates/tui/src/console/` as the single-Pod Console boundary。
+- Updated `crates/tui/src/lib.rs` routing:
+  - `LaunchMode::Panel => dashboard::launch(...)`。
+  - Console launch modes route through `console::*`。
+  - No `single_pod::run_panel` path remains。
+- Preserved `yoi panel` command name and did not add `yoi dashboard`。
+- Updated help/docs terminology: Dashboard = `yoi panel` workspace cockpit/action surface; Console = single-Pod chat/client surface; TUI = implementation umbrella。
+- Updated tests/help expectations and brittle profile-default assertions surfaced by validation。
+
+Coder validation reported:
+- `cargo test -p tui`: passed。
+- `cargo test -p yoi`: passed。
+- `cargo check --workspace --all-targets`: passed。
+- `cargo fmt --check`: passed。
+- `git diff --check`: passed。
+- `git diff --cached --check`: passed。
+- Targeted help/grep checks for Dashboard/Console terminology and no `yoi dashboard` alias: passed。
+- `nix build .#yoi --no-link` not run because package/source filters were not changed。
+
+Known risks / deferrals:
+- Internal `workspace_panel` naming remains in lower-level model types to avoid broad unrelated churn; user-facing docs/help and TUI entry/module boundaries now use Dashboard/Console terminology。
+
+Orchestrator evidence checked before review dispatch:
+- Implementation worktree is clean。
+- HEAD is `5415a947`。
+- Diff from acceptance `7e35721a..HEAD` is one implementation commit touching 12 files with a large split/rename: `single_pod.rs -> console/mod.rs`, `multi_pod.rs -> dashboard/mod.rs`, new `dashboard/render.rs`, new `dashboard/tests.rs`, docs/help/prompt updates。
+- `git diff --check 7e35721a..HEAD` produced no diagnostics。
+
+Next action:
+- Dispatch Reviewer for r1 review against Ticket requirements, with focus on behavior preservation, `yoi panel` command preservation/no alias, Dashboard/Console/TUI terminology, entrypoint/module boundary, large-file split quality, tests, and whether changed prompt/help wording is appropriate。

+## Review: request changes
+
+Verdict: `request_changes`
+
+確認範囲:
+- Ticket contract / Orchestrator IntentPacket。
+- Implementation diff: `7e35721a..5415a947`。
+- 主な対象: `crates/tui/src/lib.rs`, `crates/tui/src/dashboard/mod.rs`, `crates/tui/src/dashboard/render.rs`, `crates/tui/src/dashboard/tests.rs`, `crates/tui/src/console/mod.rs`, `crates/yoi/src/main.rs`, `crates/yoi/src/ticket_cli.rs`, `crates/tui/src/spawn.rs`, README / TUI README / development docs / prompt resource terminology changes。
+
+Positive findings:
+- `yoi panel` remains the CLI command。
+- `yoi dashboard` alias は見つからない。
+- `LaunchMode::Panel` は Dashboard boundary を通るようになり、`single_pod::run_panel` path は見つからない。
+- `single_pod.rs` / `multi_pod.rs` は `console/` / `dashboard/` に置換されている。
+
+Blocking issues:
+
+1. Recoverable Dashboard open failures now exit `yoi panel`。
+   - Path: `crates/tui/src/dashboard/mod.rs`。
+   - Dashboard から Pod を開き、nested Console open が spawn failure/cancel など recoverable error を返すと、`app.finish_open(...)` 後に Dashboard fullscreen を抜けて function が `Ok(())` を返すように見える。
+   - Baseline `single_pod::run_panel` では recoverable nested-open failures は既存 Panel/Dashboard state に折り返され、Panel loop は継続した。
+   - Cancelled/failed Console open が workspace Dashboard を閉じるのは、Ticket の behavior preservation / Panel action model preservation 要件に反する。
+
+2. Successful return from Console discards live Dashboard state。
+   - Path: `crates/tui/src/dashboard/mod.rs`。
+   - `console::run_pod_name_nested(...)` 成功後、`app.finish_open(...)` の後に `app = load_app(runtime_command.clone()).await?;` で fresh app に置き換えている。
+   - これは baseline と `finish_open` の intent に反し、selection context、composer draft/target、notices、diagnostics、Dashboard-local UI state を失う可能性がある。
+   - Ticket は boundary/terminology refactor であり、Dashboard state preservation は reviewer focus。Live `DashboardApp` を保持し、`finish_open(...)` + existing reload/reconcile mechanism を使うべき。
+
+Required fix:
+- Successful nested Console return と recoverable nested Console failure の両方で、existing `DashboardApp` を保持して Dashboard loop を継続する。
+- `finish_open(...)` と既存 reload mechanism を使い、function return / fresh app replacement で Dashboard session state を捨てない。
+- Regression tests を追加または既存 tests を拡張し、nested open success/failure が Dashboard state/draft/selection/diagnostic を壊さず loop 継続することを可能な範囲で確認する。
+
+Non-blocking concerns:
+- `dashboard/mod.rs` はまだ大きく、action/lifecycle/snapshot/model/diagnostics/E2E fixture helpers が混在している。追加分割は follow-up でもよいが、今回の blocker fix で触るなら改善可。
+- `console/mod.rs` に Dashboard/fullscreen helper concepts が少し残る。terminal-mode bridge として許容可能だが、Console focus は維持すること。
+- `workspace_panel` / `WorkspacePanel*` naming は internal model names と見えるため blocking ではない。
+
+Reviewer validation:
+- `cargo fmt --check`: passed。
+- `git diff --check 7e35721a..HEAD`: passed。
+- `cargo test -p tui`: passed。
+- `cargo test -p yoi`: passed。
+- `cargo check --workspace --all-targets`: passed。
+- Targeted help/grep checks: no `yoi dashboard` alias or old `single_pod::run_panel` route found。
+- `nix build .#yoi --no-link` not run because no package/source-filter concern found。
+
+Worktree status at review end: tracked source tree clean; ignored `target/` only。

+Coder r1-fix report received from `yoi-coder-00001KVHX0WBE`.
+
+New fix commit:
+- `135343a2 tui: preserve dashboard after console return`
+
+Branch commits now:
+- `135343a2 tui: preserve dashboard after console return`
+- `5415a947 tui: introduce dashboard console boundaries`
+
+Fix summary:
+- `crates/tui/src/dashboard/mod.rs`:
+  - Added `finish_nested_console_open(...)` helper。
+  - Successful nested Console return now calls `app.finish_open(...)` and continues the Dashboard loop with the same `DashboardApp`。
+  - Recoverable nested Console failures now call `app.finish_open(...)` and continue the Dashboard loop instead of leaving fullscreen / exiting。
+  - Non-recoverable errors still leave Dashboard fullscreen and bubble the error。
+  - Removed fresh `load_app(...)` replacement after Console return, preserving selection, composer draft, diagnostics, notices, and other local Dashboard state。
+- `crates/tui/src/dashboard/tests.rs`:
+  - Added regression coverage for nested Console success continuing without dropping Dashboard state。
+  - Added regression coverage for recoverable nested Console failure continuing without dropping Dashboard state。
+  - Added regression coverage for non-recoverable nested Console failure bubbling without incorrectly finishing/mutating Dashboard open state。
+
+Coder validation reported as passing:
+- `cargo fmt --check`
+- `git diff --check`
+- `git diff --check 7e35721a..HEAD`
+- `cargo test -p tui`
+- `cargo test -p yoi`
+- `cargo check --workspace --all-targets`
+- Targeted grep/help checks for Dashboard/Console/TUI terminology, `LaunchMode::Panel => dashboard::launch(...)`, no `single_pod::run_panel`, and no `yoi dashboard` alias。
+
+Orchestrator evidence checked before r2 review:
+- Implementation worktree is clean。
+- HEAD is `135343a2`。
+- Fix diff from `5415a947..HEAD` touches `crates/tui/src/dashboard/mod.rs` and `crates/tui/src/dashboard/tests.rs`, about 95 insertions / 15 deletions。
+- Overall `git diff --check 7e35721a..HEAD` produced no diagnostics。
+
+Next action:
+- Route back to Reviewer for r2 verification of Dashboard state preservation and final acceptance criteria。

+## Review: approve
+
+Verdict: `approve`
+
+確認範囲:
+- Ticket contract / Orchestrator IntentPacket を再確認。
+- Fix diff: `5415a947..135343a2`。
+- Overall implementation diff: `7e35721a..135343a2`。
+- 主な対象: `crates/tui/src/dashboard/mod.rs`, `crates/tui/src/dashboard/tests.rs`, Dashboard/Console/TUI terminology, CLI help, `LaunchMode::Panel` routing, `yoi dashboard` alias absence, old `single_pod::run_panel` / `multi_pod` route absence, nested Console open 後の Dashboard state preservation。
+
+Previous blockers verification:
+- Recoverable Dashboard open failures no longer exit `yoi panel`。
+  - `finish_nested_console_open(...)` により recoverable errors は `app.finish_open(...)` 後に `Ok(())` を返し、Dashboard loop が継続する。
+  - Non-recoverable errors のみ fullscreen を離れて bubble する。
+- Successful Console return no longer replaces live `DashboardApp`。
+  - 以前の `app = load_app(runtime_command.clone()).await?` replacement は削除済み。
+  - Success は `app.finish_open(...)` 後に同じ `DashboardApp` で継続する。
+  - Regression tests は success / recoverable failure / non-recoverable failure を cover している。
+
+Blocking issues: none。
+
+Non-blocking concerns / follow-ups:
+- `dashboard/mod.rs` はまだ大きく複数責務を持つが、旧 `multi_pod.rs` / `single_pod.rs` boundary より materially better であり、この Ticket の acceptance では blocking ではない。
+- Package/source-filter/resource inclusion concern は見つからなかったため、Reviewer は Nix validation を実行していない。
+
+Reviewer validation:
+- `cargo fmt --check`: passed。
+- `git diff --check 7e35721a..HEAD`: passed。

+  - Console / Dashboard / TUI terminology appears as expected。
+  - no `yoi dashboard` alias found。
+  - old `single_pod.rs` / `multi_pod.rs` absent。
+  - `LaunchMode::Panel => dashboard::launch(runtime_command).await` confirmed。

+
+## Background
+
+ユーザー要望: `WebFetch` で PDF URL を取得し、LLM が読める bounded text として返せるようにする。調査は同一会話内で完了済みで、初期実装は semantic な「PDF to Markdown」ではなく、PDF から page-delimited な Markdown-ish text を抽出する方針とする。
+
+現状:
+
+- `crates/tools/src/web.rs` の `WebFetch` は HTML / text / JSON / XML-ish content のみを許可し、`application/pdf` は unsupported Content-Type として拒否する。
+- 既存の `render_content()` は `reject_binary(bytes)` と UTF-8 decode 前提なので、PDF binary を既存 text path に乗せることはできない。
+- `WebFetch` の既存 safety behavior は維持する必要がある: private/local host rejection、bounded redirects、`max_response_bytes`、`max_output_bytes`、untrusted content warning。
+
+調査結論:
+
+- 初期実装には `pdf-extract` crate が最有力。
+  - MIT license。
+  - pure Rust。
+  - native/system dependency なし。
+  - memory buffer API あり。
+  - page split API `pdf_extract::extract_text_from_mem_by_pages()` あり。
+- Poppler / `pdftotext` は GPL / system dependency / deployment / Nix packaging の重さから採用しない。
+- `pdfium-render` は Pdfium native library が必要で、初期の text extraction には重すぎるため採用しない。
+- `unpdf` / `pdf_oxide` / `spectre_pdf` 等は Markdown-oriented な候補だが、初期採用には成熟度・audit が不足気味。必要なら follow-up で比較する。
+
+## Requirements
+
+- `WebFetch` が `application/pdf` response を unsupported Content-Type として拒否せず処理できる。
+- PDF binary bytes は既存の UTF-8 text path / `reject_binary()` path と分離して扱う。
+- `pdf_extract::extract_text_from_mem_by_pages()` を使い、page ごとに抽出した text を Markdown-ish に整形する。
+- 出力例:
+
+```markdown
+## Page 1
+
+...
+
+## Page 2
+
+...
+```
+
+- `transformed_as` は `pdf_text_by_pages` など、semantic Markdown 化を約束しない名前にする。
+- result JSON に PDF 用 metadata を追加する。
+- text/html / JSON / XML / text の既存挙動と `html_extraction` metadata を regress させない。
+- `WebFetch` の既存 bounds と safety behavior を維持する。
+
+## Acceptance criteria
+
+- `application/pdf` response が bounded text result を返す。
+- PDF response では `render_content()` の UTF-8 decode 前提 path を通らず、PDF 専用 extraction path が使われる。
+- `pdf_extract::extract_text_from_mem_by_pages()` により、page delimiter 付き Markdown-ish text が返る。
+- result JSON に `pdf_extraction` metadata が含まれる。
+- `max_output_bytes` を超える抽出結果は既存 truncation marker で切り詰められ、`output_truncated` が正しく立つ。
+- `max_response_bytes` / Content-Length check / redirect limit / private host rejection / embedded credential rejection は既存通り維持される。
+- malformed PDF / encrypted PDF / text のない PDF で panic しない。diagnostic error または readable=false 相当の metadata を返す。
+- PDF 以外の unsupported binary content は引き続き拒否される。
+- 既存 WebFetch HTML reader tests が通る。
+
+## Binding decisions / invariants
+
+- `WebFetch` は fetch/extraction tool のままとし、LLM summarization や multi-page research orchestration は入れない。
+- 初期実装では semantic な「PDF to Markdown」を約束しない。page-delimited Markdown-ish text extraction として扱う。
+- 初期実装で対応する MIME は `application/pdf` のみとする。`application/x-pdf`、`application/acrobat`、`application/octet-stream` with `.pdf`、extension sniffing は必要なら follow-up。
+- `max_response_bytes` default は変更しない。大きい PDF が必要な場合は既存 config override を使う。
+- Poppler / Pdfium / subprocess `pdftotext` / system native dependency は導入しない。
+- OCR、scanned PDF 対応、画像抽出、rendering、table reconstruction、2-column layout の完全復元、heading inference、PDF 保存/cache は範囲外。
+- PDF 抽出結果も untrusted content として扱い、既存の warning / network safety / bounds を弱めない。
+
+## Implementation latitude
+
+- PDF metadata は互換性重視で `pdf_extraction` を新設するのが推奨。既存 `html_extraction` は残す。
+- `pdf_extraction` metadata の具体フィールドは実装時に調整してよいが、少なくとも method / pages or pages_included / readable / error diagnostic 相当が分かるようにする。
+- PDF extraction は CPU-heavy になり得るため、可能なら `spawn_blocking` 等で async runtime を塞がない設計にする。ただし Rust parser の強制 cancel までは初期実装の必須条件にしない。
+- 抽出品質が `pdf-extract` で明確に不足する場合は、実装を歪めず、別 Ticket で `unpdf` / `pdf_oxide` 等を比較する。
+
+## Readiness
+
+- readiness: implementation_ready
+- risk_flags: [security, dependency, public-api, output-bounds]
+
+## Escalation conditions
+
+- `pdf-extract` が実装上致命的に使えない、または license/build/security 上の問題が見つかった場合は実装前に戻す。
+- Tool result JSON shape に breaking change が必要になりそうな場合は、既存互換を維持する案を先に提示する。
+- PDF fixture で parser panic / runaway CPU / excessive memory の懸念が出た場合は、bounds 追加または別方針を提案する。
+- Nix packaging / Cargo.lock / cargoHash 影響が大きい場合は実装報告で明示する。
+
+## Validation
+
+- focused tests:
+  - small valid PDF fixture returns expected text。
+  - multi-page PDF fixture returns `## Page 1` / `## Page 2`。
+  - output truncation sets `output_truncated`。
+  - unsupported binary non-PDF remains rejected。
+  - oversized PDF Content-Length remains rejected。
+  - existing WebFetch HTML reader behavior remains unchanged。
+- commands:
+  - `cargo fmt --check`
+  - `cargo test -p tools web`
+  - `cargo check -p tools`
+  - `git diff --check`
+  - `TicketDoctor` if Ticket consistency needs checking。

+## Decision
+
+Routing decision: implementation_ready_parallel
+
+Reason:
+- Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
+- User standing directive: blocker が無いものは並列実行する。現在の `00001KVJABS1A` は Profile scope review 中であり、WebFetch PDF 実装とは domain/file conflict がないため並列化できる。
+- Ticket body は調査済みの PDF extraction 方針、`pdf-extract` 採用理由、binary path 分離、page-delimited Markdown-ish output、metadata、bounds、non-goals、validation を実装可能な粒度で定義している。
+- 未解決 relation blocker はない。
+- Orchestrator worktree は clean、matching branch/worktree はなし。
+- Risk domain は security / dependency / public-api / output-bounds だが、Ticket は existing WebFetch network safety、`max_response_bytes` / `max_output_bytes`、unsupported binary rejection、no OCR/semantic Markdown/native dependency を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVJA7V2R` body / thread / relations / artifacts。
+- `TicketRelationQuery(00001KVJA7V2R)`: no blockers。
+- `TicketOrchestrationPlanQuery(00001KVJA7V2R)`: no previous plan records; accepted plan recorded now。
+- Workspace state:
+  - Orchestrator worktree clean at `36b9ed45`。
+  - queued: `00001KVJA7V2R`, `00001KVJDJD02`。
+  - inprogress: `00001KVJABS1A` review only。
+  - no matching WebFetch PDF branch/worktree。
+
+IntentPacket:
+
+Intent:
+- Extend `WebFetch` so `application/pdf` can be fetched and returned as bounded, page-delimited text suitable for LLM reading。
+- Use `pdf_extract::extract_text_from_mem_by_pages()` and present output as Markdown-ish page sections, not semantic PDF-to-Markdown。
+
+Binding decisions / invariants:
+- Keep WebFetch as fetch/extraction tool; no summarization or research orchestration。
+- PDF bytes must not go through the UTF-8 text / `reject_binary()` path。
+- Preserve private/local host rejection, bounded redirects, Content-Length / `max_response_bytes`, `max_output_bytes`, embedded credential rejection, untrusted content warning。
+- Initial supported MIME is `application/pdf` only; no extension sniffing or `application/octet-stream` PDF guessing。
+- No Poppler/Pdfium/subprocess/native dependency/OCR/scanned-PDF support/table reconstruction/cache。
+- Existing HTML/text/JSON/XML behavior and `html_extraction` metadata must not regress。
+- New metadata should use `pdf_extraction` with method/pages/readable/diagnostic information。
+
+Requirements / acceptance criteria:
+- Valid PDF returns `## Page 1`, `## Page 2`, etc. page-delimited bounded text。
+- `transformed_as` communicates `pdf_text_by_pages` or equivalent, not semantic Markdown。
+- `output_truncated` is correct when PDF text exceeds `max_output_bytes`。
+- Malformed/encrypted/textless PDFs do not panic; return diagnostic error or readable=false metadata。
+- Non-PDF unsupported binary remains rejected。
+- Focused WebFetch tests and relevant cargo/fmt/diff validation pass。
+
+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。

+
+Implementation orchestration start:
+- Acceptance records were committed on Orchestrator branch: `e752a720 ticket: accept webfetch pdf and intake gate`。
+- Created implementation worktree `/home/hare/Projects/yoi/.worktree/00001KVJA7V2R-webfetch-pdf-text` on branch `impl/00001KVJA7V2R-webfetch-pdf-text` at `e752a720`。
+- Spawned Coder Pod `yoi-coder-00001KVJA7V2R` with write scope limited to the implementation worktree and read-only root scope only for runtime workspace identity。
+- Coder task explicitly forbids root/original workspace implementation, semantic PDF Markdown/OCR/native dependency scope creep, merge, Ticket close, and cleanup。

+
+Known risks / deferrals:
+- Only `application/pdf` is supported; no extension sniffing or `application/octet-stream` PDF guessing。

+- Ticket contract / Orchestrator IntentPacket。
+- Implementation diff: `e752a720..b1af95ad`。
+- 主な対象:
+  - `crates/tools/src/web.rs`
+  - `crates/tools/Cargo.toml`
+  - `Cargo.lock`
+  - `package.nix`
+
+Approval evidence:
+- WebFetch safety pipeline は PDF rendering 前にも共有されている。
+  - URL validation。
+  - Redirect validation。
+  - Content-Length rejection。
+  - Bounded body read。
+- PDF classification は exact `application/pdf` のみで、extension sniffing や `application/octet-stream` guessing は追加されていない。
+- PDF path は `reject_binary()` / UTF-8 text decoding を bypass し、`pdf_extract::extract_text_from_mem_by_pages()` を `spawn_blocking` 内で使っている。
+- Output は `## Page N` 形式の page-delimited text。
+- `transformed_as` / `pdf_extraction.method` は `pdf_text_by_pages` を使い、semantic Markdown fidelity は主張していない。
+- PDF rendering 後も `max_output_bytes` truncation が適用されている。
+- Existing HTML extraction metadata は維持され、PDF result は `html_extraction = null` / `pdf_extraction` populated になる。
+- `pdf-extract` dependency inspection では Poppler/Pdfium/subprocess/OCR runtime dependency は見つからない。
+
+Blocking issues: none。
+
+Non-blocking concerns / follow-ups:
+- Valid multi-page PDF、PDF output truncation、malformed PDF error、unsupported non-PDF binary rejection の tests はあるが、encrypted/textless PDF と oversized PDF `Content-Length` の dedicated tests は無い。実装上は textless pages は readable=false metadata、Content-Length rejection は content-type rendering 前の shared path で covered されるため、この Ticket では blocking ではない。
+- Malformed PDF は `pdf_extraction` metadata付き JSON result ではなく `ToolError` を返すが、Ticket は “diagnostic error or readable=false metadata” を許容しているため OK。
+
+Reviewer validation:
+- `cargo fmt --check`: passed。
+- `git diff --check e752a720..HEAD`: passed。
+- `cargo test -p tools web`: passed, 19 tests。
+- `cargo check -p tools`: passed。
+- `cargo tree -p pdf-extract`: inspected; native PDF runtime dependencyなし。

+
+## 背景
+
+`yoi pod` の Profile launch で workspace-local `.yoi/override.local.toml` に `[[scope.allow]]` を追加しても、起動後の Pod が追加 scope を読めない問題がある。
+
+調査では、resolver は override を検出しており、Pod metadata の `resolved_manifest_snapshot.profile.workspace_override` に override path も記録されていた。一方で、最終的な `resolved_manifest_snapshot.scope.allow` には workspace root の write scope だけが残り、override 由来の追加 read scope が消えていた。
+
+原因は `crates/pod/src/entrypoint.rs` の `apply_profile_launch_policy()` が Profile launch 時に `manifest.scope` を `workspace_scope(...)` で丸ごと再代入しているため。`crates/manifest/src/profile.rs` で workspace override は一旦 merge されるが、その後段で scope が上書きされる。
+
+再現例:
+
+```toml
+# /home/hare/Projects/yoi-discord-bridge/.yoi/override.local.toml
+[[scope.allow]]
+target = "/home/hare/Projects/yoi"
+permission = "read"
+recursive = true
+```
+
+`yoi-discord-bridge` Pod の metadata では `workspace_override` は上記 override を指すが、`resolved_manifest_snapshot.scope.allow` に `/home/hare/Projects/yoi` が含まれない。
+
+## 要件
+
+- Profile launch policy は workspace 用の安全な既定 scope / delegation を付与しつつ、Profile/override で明示された追加 `scope.allow` を失わない。
+- workspace root write scope と `.worktree` write deny の既定挙動は維持する。
+- Ticket role 用の Profile launch policy でも、既存の role 制約を破らない形で追加 scope の扱いを明確化する。
+- `resolved_manifest_snapshot` に保存される最終 Manifest が、実際に model/tool に提示される readable/writable scope と一致する。
+
+## 受け入れ条件
+
+- `.yoi/override.local.toml` の追加 `[[scope.allow]]` が Profile launch 後の `resolved_manifest_snapshot.scope.allow` に残ることをテストで確認する。
+- 通常 Pod launch で workspace root write scope と `.worktree` write deny が引き続き付与されることを確認する。
+- Ticket role launch の scope/delegation 既定が壊れていないことを確認する。
+- 既存 metadata snapshot を restore する場合に override が再評価されない挙動は、今回の修正対象外または明確に別問題として扱う。

+## Resolution
+
+`00001KVJABS1A` を完了しました。
+
+実装内容:
+- Profile launch policy が `manifest.scope` を wholesale replacement しないように修正しました。
+- 既に解決済みの Profile / workspace override scope に対して、launch-policy default rules を missing rules として append するようにしました。
+- `.yoi/override.local.toml` 等で指定された追加 `scope.allow` / `scope.deny` は保持されます。
+- Normal launch の workspace root write scope と `.worktree` write deny は維持されます。
+- Ticket role launch の default direct scope / delegation defaults は維持されます。
+- Final manifest/snapshot と tool-visible scope が同じ final effective scope を見るように維持しました。
+- Restore path は existing `resolved_manifest_snapshot` を使う挙動のままで、override 再評価は追加していません。
+
+主な commit:
+- `0717aae3 pod: preserve profile override scope`
+- `a1386881 merge: profile override scope`
+
+Review:
+- r1 は `approve`。
+- Reviewer は scope merge semantics、no authority broadening、workspace write / `.worktree` deny preservation、Ticket role defaults、snapshot/tool-visible scope consistency、restore non-goal preservation を確認しました。
+
+最終 validation:
+- `cargo fmt --all --check`
+- `git diff --check HEAD^1..HEAD`
+- `cargo test -p pod entrypoint::tests::`
+- `cargo check -p pod`
+
+Known unrelated note:

+
+## Decision
+
+Routing decision: implementation_ready
+
+Reason:
+- Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
+- Ticket body は Profile launch 時に workspace override 由来の追加 `scope.allow` が `apply_profile_launch_policy()` の `workspace_scope(...)` 再代入で失われる具体原因、再現例、維持すべき既定 scope / delegation、Ticket role policy、受け入れ条件を実装可能な粒度で定義している。
+- 未解決 relation blocker はない。
+- 現在 queued はこの Ticket のみ、inprogress は 0 件、child implementation Pods はなし、matching branch/worktree はなし、Orchestrator worktree は clean。
+- Risk domain は scope / profile / launch-policy / security boundary だが、Ticket は workspace root write scope と `.worktree` write deny の維持、Ticket role launch constraints、snapshot と tool-visible scope の一致、restore non-goal を明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVJABS1A` body / thread / relations / artifacts。
+- `TicketRelationQuery(00001KVJABS1A)`: no blockers。
+- `TicketOrchestrationPlanQuery(00001KVJABS1A)`: no previous plan records; accepted plan recorded now。
+- Workspace state:
+  - Orchestrator worktree clean at `9e7c84a4`。
+  - queued: this Ticket only。
+  - inprogress: 0。
+  - visible Pods: self + peers only; spawned children 0。
+  - no matching implementation branch/worktree。
+
+IntentPacket:
+
+Intent:
+- Fix Profile launch policy so explicit additional `scope.allow` entries from Profile / workspace override survive the final launch policy application。
+- Preserve the safe workspace defaults and role-specific constraints while ensuring `resolved_manifest_snapshot.scope.allow` matches the actual readable/writable tool scope presented to the Pod。
+
+Binding decisions / invariants:
+- Do not discard explicit Profile/override `scope.allow` entries when adding workspace default scope。
+- Preserve normal Pod launch default workspace root write scope。
+- Preserve `.worktree` write deny default behavior。
+- Preserve Ticket role launch constraints and delegation defaults。
+- Do not re-evaluate overrides during restore from existing metadata snapshot; restore behavior is out of scope unless tests reveal an accidental regression。
+- Snapshot saved in Pod metadata must reflect final effective manifest/scope, not an intermediate manifest。
+- Avoid broad profile/config semantics changes beyond launch policy scope merging。
+
+Requirements / acceptance criteria:
+- Test that `.yoi/override.local.toml` extra `[[scope.allow]]` remains in `resolved_manifest_snapshot.scope.allow` after Profile launch。
+- Test that normal Pod launch still receives workspace root write scope and `.worktree` write deny。
+- Test that Ticket role launch scope/delegation defaults are not broken。
+- Relevant `cargo test` / `cargo check` / `cargo fmt --check` / `git diff --check` pass。
+
+Escalate if:
+- Fixing the merge would broaden runtime authority beyond explicit profile/override scope。
+- Current scope model cannot distinguish launch-policy default grants from user-specified grants without a schema/API decision。
+- Ticket role policy requires an authority decision not specified in the Ticket。
+
+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。

+
+Implementation commit:
+- `0717aae3 pod: preserve profile override scope`
+
+Changed areas reported:
+- `crates/pod/src/entrypoint.rs`:
+  - Profile launch policy no longer replaces `manifest.scope` wholesale。
+  - It appends missing launch-policy default scope rules onto the already-resolved Profile/override scope。
+  - Explicit `scope.allow` / `scope.deny` entries from Profile and `.yoi/override.local.toml` are preserved。
+  - Normal workspace write scope and `.worktree` write deny remain applied for normal launches。
+  - Ticket role launch defaults/delegation behavior remains applied。
+  - Added focused tests for:
+    - `.yoi/override.local.toml` extra `[[scope.allow]]` surviving Profile launch in final manifest/snapshot serialization。
+    - Normal launch keeping workspace write + `.worktree` deny while preserving explicit Profile scope。
+    - Orchestrator role launch keeping read-root/worktree delegation defaults while preserving explicit Profile scope。
+
+Coder validation reported:
+- `cargo test -p pod entrypoint::tests::`: passed, 22 tests。
+- `cargo check -p pod`: passed。
+- `cargo fmt --all --check`: passed。
+- `git diff --check`: passed。

+  - `prompt::catalog::tests::pod_orchestration_guidance_section_renders_resource_body`
+  - `prompt::system::tests::pod_orchestration_guidance_is_included_for_pod_management_tools`
+  - Missing text asserted: `"worktree status, diff, and test results"`。
+- Nix not run because no packaging/source-filter/dependency files changed。

+
+Next action:
+- Dispatch Reviewer for r1 review against Ticket requirements, with focus on scope allow/deny merge semantics, authority boundary/no broadening beyond explicit override + defaults, workspace write / `.worktree` deny preservation, Ticket role policy preservation, snapshot/tool-visible scope consistency, and whether the full `cargo test -p pod` failure is unrelated/pre-existing。

+---
+
+## Background
+
+Intake がユーザー発話をそのまま Ticket 化しようとし、Ticket 作成前に必要な既存 Ticket / docs / code / workflow 調査を十分に行わない挙動が観測されている。
+
+今回の Intake 調査では、workspace 側の `.yoi/workflow/ticket-intake-workflow.md` には既存 Ticket 確認、関連 docs/code/workflow/history の確認、readiness 分類、ユーザー合意前に official Ticket を作らないことが書かれている一方で、以下の弱さが見えた。
+
+- `resources/prompts/role/intake.md` は role prompt として短く、`create or update the appropriate Ticket` の重みが強い。
+- `resources/workflows/ticket-intake-workflow.md` は workspace workflow snapshot より薄く、Ticket 化前の調査ゲート、draft-before-create、user agreement gate、`spike_needed` の扱いが弱い。
+- workspace workflow でも「必要に応じて関連 docs / code / workflow / history を読む」が optional に読めるため、曖昧な依頼で調査せず draft/Ticket 化へ倒れやすい。
+- draft template に `Action required` / `Attention required` が残っており、現在の Ticket schema / vocabulary とずれた文言が残っている。
+
+関連して参照した既存 Ticket:
+
+- `00001KTAZ2401` Ticket intake workflow
+- `00001KT0JPZS0` Built-in Ticket intake and orchestration routing
+- `00001KTRKZ14C` Project workflows を public builtin と dogfood 運用に分離する
+- `00001KSKBPHRG` Prompt / Workflow 評価メトリクスと改善 Offer
+
+## Requirements
+
+- Intake role prompt に「Ticket 化前の最小調査」を明示する。
+- Ticket intake workflow に、以下を binding step として追加または強調する。
+  - 既存 Ticket / workflow / relevant files を読むべき条件。
+  - 調査不足なら `TicketCreate` せず、draft または `spike_needed` / `requirements_sync_needed` として止めること。
+  - ユーザー主張、Intake が確認した事実、未確認仮説を Ticket draft 上で分けること。
+  - “言われたことそのまま” を requirements / acceptance criteria にしないこと。
+- `resources/workflows/ticket-intake-workflow.md` と workspace workflow `.yoi/workflow/ticket-intake-workflow.md` の役割差を確認し、必要なら bundled 側も詳細化する。
+- stale な `Action required` / `Attention required` 語彙を削除または現在の Ticket 運用に合う表現へ置換する。
+- Intake が coder / reviewer / read-only investigation helper Pod を起動しない境界は維持する。
+
+## Acceptance criteria
+
+- Intake が曖昧な依頼を受けた時、`TicketCreate` より先に duplicate / related work / relevant docs-code-workflow の確認を行うべき条件が model-facing prompt/workflow に明文化されている。
+- 調査が必要な依頼では、Intake が `spike_needed` または `requirements_sync_needed` として draft 提示に留められることが prompt/workflow 上で明示されている。
+- role prompt が “create/update Ticket” だけでなく “materialize 前に十分に調査し、未確認事項を分離する” ことを明示している。
+- bundled workflow resource と workspace workflow の不整合が解消されるか、意図した差分として短く説明されている。
+- Ticket 作成前の user agreement rule は維持されている。
+- stale な `Action required` / `Attention required` が新規 draft template から消えるか、現行 schema と矛盾しない説明に置き換わっている。
+
+## Binding decisions / invariants
+
+- Intake は scheduler ではなく、coder / reviewer / read-only investigation helper Pod を起動しない。
+- Intake は implementation worktree 作成、implementation routing、review routing、merge、close を行わない。
+- ユーザー合意なしに official Ticket を作らないルールは維持する。
+- Ticket body には、ユーザー主張、Intake が確認した事実、未確認仮説、未決定点を混同して保存しない。
+- Prompt / workflow 文言は `resources/prompts` / `resources/workflows` と workspace workflow override の責務境界を崩さない。
+
+## Implementation latitude
+
+- prompt / workflow 文言の修正で足りるならコード変更しない。
+- 実例セッションが必要なら、`~/.yoi/sessions` の該当 transcript を小さく確認して原因分析に使ってよい。ただし raw private context や不要な transcript 全文を Ticket に保存しない。
+- `00001KSKBPHRG` の prompt/workflow evaluation work と接続して、将来的な評価シナリオにするのは可。
+- bundled workflow と dogfood workspace workflow を完全一致させる必要はないが、差分がある場合は意図を説明できる状態にする。
+
+## Readiness
+
+- readiness: implementation_ready
+- risk_flags: [prompt-context, workflow-source, role-behavior, ticket-authority]
+
+## Escalation conditions
+
+- Intake の観測挙動が prompt/workflow ではなく Panel handoff、workflow selection、role profile resolution、または active workflow snapshot の問題に見える場合。
+- workflow source priority や builtin/workspace override semantics の設計変更が必要になる場合。
+- session history を読まないと原因を特定できず、かつ transcript に private context が含まれる可能性がある場合。
+
+## Validation
+
+- prompt / workflow diff review。
+- `git diff --check`。
+- 必要に応じて `yoi ticket doctor`。
+- 可能なら Intake の小さな再現シナリオで、曖昧な依頼に対して `TicketCreate` せず調査/draft に留まることを確認する。

+## Resolution
+
+`00001KVJDJD02` を完了しました。
+
+実装内容:
+- `resources/prompts/role/intake.md` に official `TicketCreate` 前の minimum investigation gate を追加しました。
+- Intake が user claims / confirmed facts / unverified hypotheses / undecided points を区別するように model-facing guidance を補強しました。
+- User agreement before official Ticket creation を維持・明確化しました。
+- Intake non-scheduler boundary を補強しました。
+  - coder/reviewer/read-only helper Pod spawn なし。
+  - worktree作成なし。
+  - implementation/review routing、merge、close なし。
+- `resources/workflows/ticket-intake-workflow.md` を concrete reusable Intake procedure に拡張しました。
+- `.yoi/workflow/ticket-intake-workflow.md` を bundled workflow と整合させつつ、dogfooding/workspace-specific details を維持しました。
+- Investigation が必要な場合、`requirements_sync_needed` / `spike_needed` / `blocked` の draft stop behavior を明示しました。
+- `Action required` / `Attention required` の stale wording を touched templates から削除し、current Ticket-operation vocabulary に置換しました。
+
+主な commit:
+- `1143ae1c workflow: add intake investigation gate`
+- `f62ed4db merge: intake investigation gate`
+
+Review:
+- r1 は `approve`。

+- stale vocabulary grep: `Action required` / `Attention required` no matches in touched files。
+- investigation vocabulary grep: expected terms present。
+- `TicketDoctor`: 0 errors。
+
+Known unrelated note:
+- `TicketDoctor` は既存 Ticket の warning 4 件を返しましたが、この Ticket の変更とは無関係です。

+
+## Decision
+
+Routing decision: implementation_ready_parallel
+
+Reason:
+- Panel Queue により、この Ticket は Orchestrator routing 対象として明示許可された。
+- User standing directive: blocker が無いものは並列実行する。現在の `00001KVJABS1A` review と WebFetch PDF work とは別 domain の prompt/workflow resource修正であり、直接 conflict はないため並列化できる。
+- Ticket body は Intake role prompt / workflow の弱点、Ticket 化前調査 gate、draft-before-create、user agreement gate、spike/requirements_sync handling、stale vocabulary removal、Intake boundaries を実装可能な粒度で定義している。
+- 未解決 relation blocker はない。
+- Orchestrator worktree は clean、matching branch/worktree はなし。
+- Risk domain は prompt-context / workflow-source / role-behavior / ticket-authority だが、Ticket は Intake が coder/reviewer/helper Pod を起動しないこと、implementation routing/merge/closeをしないこと、user agreement without official Ticket create ruleを維持することを明示している。bounded context check 後も implementation 前に必要な追加 human decision は見つからなかった。
+
+Evidence checked:
+- Ticket `00001KVJDJD02` body / thread / relations / artifacts。
+- `TicketRelationQuery(00001KVJDJD02)`: no blockers。
+- `TicketOrchestrationPlanQuery(00001KVJDJD02)`: no previous plan records; accepted plan recorded now。
+- Workspace state:
+  - Orchestrator worktree clean at `36b9ed45`。
+  - queued: `00001KVJA7V2R`, `00001KVJDJD02`。
+  - inprogress: `00001KVJABS1A` review only。
+  - no matching Intake workflow branch/worktree。
+
+IntentPacket:
+
+Intent:
+- Strengthen Intake model-facing role/workflow guidance so ambiguous requests go through a minimum investigation gate before official Ticket creation。
+- Make Intake separate user claims, confirmed facts, unverified hypotheses, and undecided points in drafts/Tickets。
+
+Binding decisions / invariants:
+- Intake remains non-scheduler and must not spawn coder/reviewer/read-only investigation helper Pods。
+- Intake must not create implementation worktrees, route implementation/review, merge, or close。
+- User agreement before official Ticket creation remains required。
+- Do not save user claims, confirmed facts, unverified hypotheses, and undecided points as if they are all requirements。
+- Preserve prompt/workflow resource boundaries between bundled resources and workspace override; explain intended differences if they remain。
+- Remove or replace stale `Action required` / `Attention required` vocabulary in draft templates with current Ticket-operation language。
+
+Requirements / acceptance criteria:
+- Intake prompt/workflow explicitly states when to inspect existing Tickets / workflows / relevant files before TicketCreate。
+- If investigation is needed, Intake can stop at draft / `spike_needed` / `requirements_sync_needed` rather than official Ticket creation。
+- `resources/prompts/role/intake.md`, `resources/workflows/ticket-intake-workflow.md`, and `.yoi/workflow/ticket-intake-workflow.md` are reconciled or their differences are intentional/clear。
+- Ticket作成前 user agreement rule is preserved。
+- Validation includes prompt/workflow diff review and `git diff --check`; run TicketDoctor if Ticket consistency needs checking。
+
+Next action:
+- Record `queued -> inprogress` and commit Ticket records before creating implementation worktree and spawning Coder。

+## Implementation report
+
+Coder implementation report received from `yoi-coder-00001KVJDJD02`.
+
+Implementation commit:
+- `1143ae1c workflow: add intake investigation gate`
+
+Changed areas reported:
+- `resources/prompts/role/intake.md`:
+  - Added explicit minimum investigation gate before `TicketCreate` / material refinement。
+  - Reinforced user agreement before official Ticket creation。
+  - Added separation of user claims, confirmed facts, unverified hypotheses, and undecided points。
+  - Preserved Intake non-scheduler boundaries: no coder/reviewer/helper Pods, no worktrees, no routing/merge/close。
+- `resources/workflows/ticket-intake-workflow.md`:
+  - Expanded bundled workflow from thin pointer into concrete reusable Intake procedure。
+  - Added Ticket化前の最小調査ゲート。
+  - Added `spike_needed` / `requirements_sync_needed` draft stop behavior。
+  - Replaced stale `Action required` / `Attention required` draft wording with `Next Ticket operation`。
+  - Added recommended Ticket body sections for claims/facts/hypotheses/open questions。
+  - Documented bundled-vs-workspace workflow boundary。
+- `.yoi/workflow/ticket-intake-workflow.md`:
+  - Reconciled workspace override with bundled workflow while preserving dogfooding-specific details。
+  - Added explicit local investigation gate conditions and outputs。
+  - Updated draft template and Ticket body guidance。
+  - Clarified that workspace override may add Objective/split/local policy details but must not weaken bundled invariants。
+
+Coder validation reported:
+- `git diff --check`: passed。
+- Stale vocabulary grep for `Action required` / `Attention required` in touched prompt/workflow files: no matches。
+- Investigation-gate grep confirmed new terms are present:
+  - `minimum investigation gate`
+  - `Ticket 化前の最小調査ゲート`
+  - `spike_needed`
+  - `requirements_sync_needed`
+  - `Confirmed facts / sources`
+  - `Unverified hypotheses`
+  - `Undecided points / open questions`
+- Workflow/prompt test search: no dedicated workflow prompt tests found; only unrelated Dashboard test reference。
+- No code tests run because changes are prompt/workflow Markdown only。
+
+Known risks / deferrals:
+- No runtime schema/code changes were made。
+- `.yoi/workflow/ticket-intake-workflow.md` intentionally remains a more detailed workspace override; bundled workflow is compact reusable baseline。
+- `TicketDoctor` not run by Coder; no Ticket record structure was changed。
+
+Orchestrator evidence checked before review dispatch:
+- Implementation worktree is clean。
+- HEAD is `1143ae1c`。
+- Diff from acceptance `e752a720..HEAD` is one implementation commit touching 3 files, 186 insertions / 19 deletions。
+- `git diff --check e752a720..HEAD` produced no diagnostics。
+
+Next action:
+- Dispatch Reviewer for r1 review against Ticket requirements, with focus on model-facing Intake behavior, Ticket化前 investigation gate clarity, user-agreement preservation, stale vocabulary removal, bundled/workspace workflow boundary, and Intake non-scheduler boundaries。

+
+Approval evidence:
+- Intake non-scheduler boundary is preserved and strengthened。
+  - Coder/Reviewer/read-only helper Pod spawn、worktree作成、implementation/review routing、merge、close、implementation side effects をしないことが明記されている。
+- Official Ticket creation 前の user agreement rule は維持されている。
+  - Draft presentation と explicit approval / creation instruction before `TicketCreate` が必要。
+- Pre-`TicketCreate` investigation conditions are now model-facing。
+  - Duplicate/related existing Ticket checks、targeted existing Ticket read-before-update、ambiguous/current-behavior/authority-boundary/workflow-source change cases の workflow/prompt/docs/code/config/history inspection が明示された。
+- Investigation stop behavior is explicit。
+  - Gate を満たせない場合、Intake は draft で停止し `requirements_sync_needed` / `spike_needed` / `blocked` として分類する。
+- User claims / confirmed facts / unverified hypotheses / undecided points are separated in prompt, draft template, and recommended Ticket body。
+- “User said so” is explicitly barred from becoming requirements / acceptance criteria without confirmation。
+- Bundled workflow vs workspace override boundary is coherent。
+  - Bundled は reusable minimum procedure、workspace override は dogfooding-specific details を足せるが bundled invariants を弱めない、と説明されている。
+- Stale `Action required` / `Attention required` wording was removed from touched templates。
+- Changed files are limited to prompt/workflow Markdown resources; no code/runtime behavior changes found。
+
+Non-blocking concerns / follow-ups:
+- Live Intake scenario は未実行。ただし本 Ticket は prompt/workflow text only であり、acceptance validation に E2E は要求されていないため blocking ではない。
+- Reviewer は `TicketDoctor` を実行していないが、implementation worktree 側で Ticket record structure は変更されておらず、Ticket consistency concern は見つからなかった。

+- `1143ae1c workflow: add intake investigation gate`
+- `f62ed4db merge: intake investigation gate`
+
+Review:
+- r1 は `approve`。
+- Reviewer は Intake non-scheduler boundary、user agreement、Ticket 化前 investigation gate、draft stop behavior、claims/facts/hypotheses/open questions separation、bundled/workspace workflow consistency、stale vocabulary removal を確認しました。
+
+最終 validation:
+- `git diff --check HEAD^1..HEAD`
+- stale vocabulary grep: `Action required` / `Attention required` no matches in touched files。
+- investigation vocabulary grep: expected terms present。
+- `TicketDoctor`: 0 errors。
+
+Known unrelated note:
+- `TicketDoctor` は既存 Ticket の warning 4 件を返しましたが、この Ticket の変更とは無関係です。

 This guide is for building a Yoi Plugin outside the Yoi runtime codebase. It describes the current Plugin package shape, how to author a Tool Plugin, how to enable it in a workspace, and how to inspect/debug it.
 
-Yoi Plugins are intentionally explicit:
+Yoi Plugins are intentionally explicit. The Plugin system is designed around the following host-side principles:
 
-- putting a package in `.yoi/plugins` only makes it discoverable;
-- a Profile/config entry must explicitly enable it;
-- Plugin grants must allow its surfaces and host APIs;
+- package discovery is inventory only; putting a package in `.yoi/plugins` does not enable, register, or execute it;
+- a Profile/config entry must explicitly enable each Plugin package by source-qualified id, version, and digest;
+- Plugin grants must allow each surface and host API before registration or execution can use it;
 - Plugin code runs only through the configured sandbox runtime;
-- Tool calls and Tool results use the ordinary Yoi Tool/Worker history path.
+- Plugin packages do not inherit Pod workspace filesystem, network, environment, or Ticket authority;
+- Tool calls and Tool results use the ordinary Yoi Tool/Worker history path;
+- Plugin metadata, output, and diagnostics are untrusted unless Yoi host policy says otherwise.
+
+## Design intent
+
+Yoi's Plugin platform is meant to make extension behavior reviewable before it becomes model-visible. A Plugin package should answer four separate questions:
+
+1. **What is this package?** `plugin.toml` declares identity, version, runtime, surfaces, requested permissions, and Tool schemas.
+2. **Is it enabled here?** Workspace/Profile config chooses exact package refs and pinned digests.
+3. **What may it do?** Plugin grants authorize Tool surfaces and host APIs such as `https` and `fs`.
+4. **How does it interact with the model?** Tool schemas/results enter through ordinary ToolRegistry and Tool history paths.
+
+Keep these layers separate when designing a Plugin. Do not make package discovery imply enablement. Do not make SDK/PDK convenience imply authority. Do not treat Rust helper APIs or host API wrappers as permission grants. The host always re-checks authority at registration/execution/API-call boundaries.
+
+Yoi's preferred Plugin shape is **Tool first**. A good Tool Plugin has a narrow schema, deterministic input/output behavior, explicit side-effect metadata, and a minimal grant set. Long-running services, inbound events, and autonomous routing are future Service/Ingress work; they should not be hidden inside a Tool package.
+
+Component Model authoring is the preferred path for new Plugins. The raw core-Wasm ABI exists for compatibility and tests, but authors should use the Rust PDK/template unless they are deliberately testing the low-level runtime.

 `pack` rejects malformed manifests, missing runtime artifacts, symlinks/root escapes, and unsupported package shapes. The JSON output contains the stable package reference, output path, digest, entries, and safety flags. After review, copy the package to `.yoi/plugins/` (or the user Plugin store) and add explicit Profile/config enablement with pinned digest and grants; packing and checking do not do this for you.
 
+## Designing a Plugin
+
+Design a Plugin around the smallest reviewable contract that is useful to the model.
+
+For Tool Plugins:
+
+- expose one clear operation per Tool name;
+- keep the input schema narrow and explicit;
+- make side effects visible in the Tool name, description, and `external_write` / permission metadata;
+- request only the host APIs needed for that Tool;
+- prefer deterministic, structured output over conversational prose;
+- return bounded summaries and content that are useful as Tool results;
+- avoid hiding long workflows, background daemons, or inbound event handling inside a Tool call.
+
+A Tool should be a capability the model may choose to call, not a second agent runtime. If the desired behavior needs a long-lived connection, incoming events, or autonomous routing, treat that as future Service/Ingress design rather than stretching the Tool surface.
+
+Design package permissions as a review surface. A reviewer should be able to read `plugin.toml` plus the enablement grants and understand:
+
+- what Tools become model-visible;
+- what external side effects are possible;
+- what hosts or paths can be touched;
+- what data can flow back into ordinary Tool results.

+Keep role behavior here and treat the first committed user message as concrete Ticket/action context only. Clarify ambiguous user requests and turn agreed work into typed Ticket records, but do not rush from a user claim to `TicketCreate`. Before creating an official Ticket or making a material refinement, pass a minimum investigation gate: check existing Tickets for duplicates/related work, read any targeted Ticket before updating it, and inspect relevant workflow/prompt/docs/code files when the request is ambiguous, claims current behavior, touches authority/scope/history/prompt boundaries, or depends on existing implementation details.
+
+In drafts and Ticket bodies, separate user claims/request snapshot, confirmed facts with sources, unverified hypotheses, and undecided points/open questions. Do not save all user claims as requirements or acceptance criteria. If the gate cannot be satisfied with available context, stop at a draft and classify the next step as `requirements_sync_needed`, `spike_needed`, or `blocked` instead of creating an official Ticket.

+# Ticket Intake Workflow
 
-# Ticket intake workflow
+この bundled workflow は reusable な最小 Intake 手順である。Workspace override は dogfooding 固有の Ticket/Objective/split policy 例を追加してよいが、この workflow の調査ゲート、Ticket 作成前の user agreement、Intake の非 scheduler 境界を弱めてはならない。
 
-1. ユーザー依頼と既存 Ticket を同期し、重複作成を避ける。既存 Ticket を対象にする場合は body/thread/artifacts を読んでから更新する。
-2. 要件・背景・受け入れ条件・未決事項を Ticket に記録する。実装手順は必要になるまで増やしすぎない。
-3. Ticket が queue 可能な粒度と明確さになったら、typed Ticket tool surface で intake summary を残し、`state = ready` にする。未決事項がある場合は planning に留め、必要な質問やリスクを明示する。
-4. Handoff report は `created_or_updated_ticket_id`、`state`、`open_questions_or_risk_flags`、`intake_summary` を含める。
-5. Intake は実装を開始しない。ユーザーが panel 等で `ready -> queued` し、Orchestrator が queued Ticket を routing する。
+Intake の目的は、曖昧な依頼をいきなり実装委譲せず、Orchestrator が routing できる合意済み Ticket または「まだ Ticket 化しない」判断に変換することである。
+
+## 境界
+
+Intake は以下をしない。
+
+- coder / reviewer / read-only investigation helper Pod を起動しない。
+- implementation worktree を作らない。
+- implementation / review routing、merge、close、branch cleanup をしない。
+- unattended scheduler として自動実行しない。
+- ユーザー合意なしに official Ticket を作らない。
+
+## Ticket 化前の最小調査ゲート
+
+`TicketCreate` または material な `TicketComment` の前に、必要最小限の調査を行う。
+
+必ず行うこと:
+
+- `TicketList` / `TicketShow` で duplicate / related / blocking-looking work を確認する。
+- 既存 Ticket を更新する場合は、その Ticket の item/thread を読む。
+
+次のいずれかに当たる場合は、Ticket 作成前に関連 workflow / prompt / docs / code / config を読む。
+
+- ユーザー依頼が曖昧、または複数の concrete work item を含む。
+- 「現在の挙動」「既存仕様」「壊れている」「既にある」など、事実確認を要する claim がある。
+- scope / permission / history / prompt context / persistence / public API など authority boundary に触れる。
+- 既存 workflow/resource/file の文言変更や source-of-truth 境界に触れる。
+
+調査結果は draft で分けて書く。
+
+- User claims / request snapshot: ユーザーが述べたこと。
+- Confirmed facts / sources: Intake が読んで確認したことと source。
+- Unverified hypotheses: ありそうだが未確認の推測。
+- Undecided points / open questions: ユーザーまたは Orchestrator の判断が必要なこと。
+
+確認できない claim を requirements / acceptance criteria として保存しない。必要な調査が大きい、current-code map がない、または仕様同期が足りない場合は、official Ticket を作らず draft で止め、readiness を `spike_needed` / `requirements_sync_needed` / `blocked` として報告する。
+
+## 手順
+
+1. 依頼を短く言い換え、目的、影響範囲、既決事項、未決定点を分ける。この段階では Ticket を作らない。
+2. Ticket 化前の最小調査ゲートを実施する。
+3. 要件を同期する。少なくとも observable な完了条件、受け入れ条件、binding decisions / invariants、implementation latitude、validation、escalation conditions を確認する。
+4. readiness を分類する。
+
+```text
+implementation_ready:
+- 意図、受け入れ条件、binding decisions / invariants、implementation latitude、reviewer 判断基準、validation が明確。
+
+requirements_sync_needed:
+- 目的は見えているが、仕様・用語・UX・責務境界・受け入れ条件が未同期。
+
+spike_needed:
+- 技術調査、依存関係、性能、license、diagnostics、現在コード map が先に必要。
+
+blocked:
+- 人間判断、外部イベント、別 Ticket の完了が必要。
+```
+
+5. 作成前 draft を提示する。
+
+```text
+Title:
+Priority:
+Readiness:
+Next Ticket operation: draft_only | create_after_user_agreement | update_existing_after_user_agreement | no_ticket
+Risk flags:

+
+6. ユーザーの明示承認、または「作って」「切って」「記録して」など official record 作成の明示指示を待つ。
+7. 合意後だけ `TicketCreate` / `TicketComment` を使う。canonical ID は storage が割り当てるため draft では提案しない。
+8. 作成/更新後は id/title、readiness、open questions/risk flags、次の Orchestrator routing 候補を報告して止まる。
