## Intake summary

既存 Ticket は、closed 済みの `20260609-032533-001` で追加された `session-analytics` 基盤への concrete follow-up として十分に具体化済み。目的は assistant response 単位の tool batching / edit round-trip 指標を JSON report に追加することで、実装対象 metrics、断定しない diagnostics 方針、非目標、受け入れ条件、テスト観点が明記されている。未決定の product/API/authority boundary はなく、Orchestrator は implementation_ready として routing できる。Reviewer focus は、response/tool-result cycle 推定の妥当性、raw content を出さない既存 analytics privacy boundary の維持、consecutive edit-only streak の過剰断定回避、既存 CLI/JSON schema との整合性。

## State changed

Accepted queued implementation under the updated parallel-capacity policy. This Ticket extends the already-landed session analytics crate and is independent from the active ToolExecutionContext, TicketList, and Panel worktrees.

## Decision

Routing decision: implementation_ready_parallel

Reason:
- This Ticket extends `session-analytics`, a recently landed and currently inactive area.
- It is independent from active ToolExecutionContext, TicketList output, and Panel UX work.
- User asked to prefer parallel work when conflicts are absent or expected small.

IntentPacket:

Intent:
- Add assistant-response-level tool batching and edit round-trip metrics to `session-analytics` so tool-use speed patterns can be evaluated in structured JSON.

Binding decisions / invariants:
- Infer assistant response / tool-result cycle units from session JSONL as best-effort analytics.
- Add response-level tool call metrics: total responses, tool-call responses, total tool calls, avg/p50/p90/max, histogram, top responses by tool call count.
- Add edit batching metrics: Edit calls per response, responses containing Edit, same-file multiple Edit calls in one response, files touched per edit response, and correlation with large edit args where possible.
- Add consecutive edit-only response streak metrics by file/path and response range, distinguishing pure edit-only streaks from sequences broken/annotated by Read/Bash/test/result-dependent steps.
- Diagnostics must be observations such as possible batching opportunity, not blame or policy enforcement.
- Preserve existing privacy boundary: no raw user input, raw tool args, raw file contents, raw session snippets, or raw tool output content in default output.
- Do not change prompt/workflow behavior, implement EditBatch/ordered patch tools, or force batching policy.

Validation:
- Tests for single response with multiple tools.
- Tests for same-response same-file multiple Edit.
- Tests for consecutive edit-only responses to same file.
- Tests for interleaved Read/test step breaking or annotating streak.
- Tests for sessions with no edits.
- `cargo fmt --check`, `git diff --check`, `cargo run -q -p yoi -- ticket doctor`, `cargo check --workspace`, `nix build .#yoi`.
