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

+## State changed
+
+Human authorized queue routing from Workspace Dashboard. Ticket has concrete acceptance criteria, no recorded blockers, and is semantically separate from the frontend Deno tooling Ticket, so Orchestrator accepts implementation.
