## 作成 LocalTicketBackend によって作成されました。 --- ## Intake summary 既存 Ticket `00001KTR83D6E` の本文・thread・artifacts を確認し、関連する closed Ticket `00001KTNVGT8G`（ToolExecutionContext 導入）と `00001KTNS9B50`（same-file multiple Edit の analytics）も確認した。同目的の未完了重複は見当たらず、本 Ticket は `ToolExecutionContext` 基盤を使う concrete follow-up として妥当。目的は Worker の approved tool call 並列実行を維持しつつ、`Edit` / `Write` など同一 target file への built-in mutation を tool 側の per-file boundary で直列化し、同一 `batch_id` 内では `call_index` 昇順に実行すること。binding decisions は Worker に resource scheduler を持たせないこと、Hook/Interceptor に lock lifecycle を置かないこと、全 tool/全 response を直列化しないこと、分散 file lock はこの Ticket の非目標であること。実装裁量として、異なる `batch_id` の同一 file mutation に厳密 global ordering が必要か単純な per-file mutex で十分かを判断し、理由を記録する余地がある。Reviewer focus / risk flags は concurrency、path-canonicalization、scope-permission-boundary、diagnostics-privacy、failure/timeout/drop 時の guard 解放。blocking open question はなく、受け入れ条件と validation が明確なため implementation_ready と判断する。 --- ## State changed 既存 Ticket の本文・thread・artifacts と関連 Ticket を確認した。要件・非目標・受け入れ条件・レビュー焦点が実装 routing 可能な粒度で揃っているため、planning から ready にします。 --- ## State changed Ticket を `workspace-panel` が queued にしました。 --- ## State changed Queue acceptance: relation query has no blockers, orchestration-plan query only has prior human-gate waiting note, workspace is clean, and user explicitly requested continuing inprogress/queued consumption. Implementation side effects will proceed in a separate worktree/branch before reviewer evidence and merge-completion. --- ## Plan Routing decision: implementation_ready Reason: - Ticket is `queued`, relation query has no blockers, and existing orchestration plan only contains a prior human-gate waiting note. - User explicitly requested continuing inprogress/queued work; this satisfies the prior human gate. - Requirements and acceptance criteria are concrete: same-file `Edit`/`Write` ordering by `ToolExecutionContext.call_index` within a batch, no Worker-wide scheduler, different-file parallelism, guard release on error, and path equivalence coverage. Evidence checked: - Ticket body/thread/artifacts. - `TicketRelationQuery`: no relations/blockers. - `TicketOrchestrationPlanQuery`: one waiting note from prior target-unspecified routing pass. - Code map: `crates/tools/src/edit.rs`, `crates/tools/src/write.rs`, `crates/tools/src/tracker.rs`, `crates/tools/src/scoped_fs.rs`, `crates/llm-worker/src/tool.rs`, `crates/llm-worker/src/worker.rs`. - Workspace state is clean; existing separate setup-wizard worktree is independent. IntentPacket: - Intent: serialize same-target-file built-in mutations so `Edit`/`Write` calls for one file in one response execute in model call order while preserving Worker parallel tool execution. - Binding decisions / invariants: Worker must not become a general resource scheduler; do not disable provider/Worker parallel tool calls; do not serialize unrelated tools or different files; preserve existing scope/read-before-edit behavior; path keying must not weaken scope validation; no distributed lock across Pods/processes. - Requirements / acceptance criteria: same-batch same-file `Edit` order; same-batch same-file `Write` + `Edit` order; different files remain concurrent; failure releases guard; path equivalence behavior fixed by implementation/test; targeted tests and standard validation pass. - Implementation latitude: exact guard placement may be a shared file-mutation coordinator in `tools` as long as both `Edit` and `Write` share it and Worker remains parallel; for different batch same-file mutations, a simple per-file exclusion is acceptable if reason is recorded. - Escalate if implementation requires changing Worker execution semantics, tool result ordering/history semantics, permission/scope model, or broad distributed locking. - Validation: `cargo fmt`, `cargo test -p tools mutation`, focused `cargo test -p tools`, `git diff --check`, `target/debug/yoi ticket doctor`, and broader build before merge if touched surfaces require it. --- ## Implementation report Implementation report Branch/worktree: `serialize-file-mutations` / `.worktree/serialize-file-mutations` Commit: - `40130143 fix: serialize same-file mutations` Summary: - Added a shared per-target-file mutation guard to `Tracker`, keyed by canonical target path where possible. - `Edit` and `Write` acquire this guard around their critical read/verify/write/record sections, so same-file mutations serialize while Worker-level parallel tool execution remains intact. - Different files use different guards and are not globally serialized. - The guard uses `ToolExecutionContext` for response-local diagnostics/correlation (`batch_id`, `call_index`) without making it a Worker/session authority handle. - Added tests for equivalent-path guard blocking, different-file non-blocking, same-batch `Write` then `Edit` order, and failed mutation guard release. Validation run in branch: - `cargo fmt` - `cargo test -p tools --lib` passed. - `cargo test -p tools mutation_guard --lib` passed. - `cargo test -p tools write_then_edit_same_file_same_batch_uses_call_order --lib` passed. - `cargo test -p tools failed_same_file_mutation_releases_guard_for_followup --lib` passed. - `cargo check -p tools` passed. - `git diff --check` passed. Notes: - `nix build .#yoi` not yet run on this branch; Orchestrator should run it before/after merge because this changes tool runtime code and crate feature configuration. --- ## Review: approve Branch-local review verdict: approve Blockers: none. Evidence: - Diff is limited to `crates/tools`; Worker-wide scheduler semantics were not changed. - Serialization is closed over built-in `Write`/`Edit` mutation boundary. - `Write` and `Edit` share the same `Tracker` per-target-file guard. - Guard covers `Write` existing check/read/verify/write/record and `Edit` read/verify/transform/write/record critical sections. - Path keying canonicalizes target path/canonical parent/lexical fallback, while different files use different mutexes. - Tests cover same-file write→edit ordering, failed mutation release, equivalent path guard, and different-file non-blocking. Validation run by reviewer: - `cargo test -p tools --lib` passed (99 passed). - `cargo check -p tools` passed. - `git diff --check $(git merge-base HEAD develop)..HEAD` passed. - `nix build .#yoi` passed. Non-blocking note: - `ToolExecutionContext` is currently used for diagnostics/correlation, not a full call-index scheduler. Current Worker approved-call order and early guard acquisition satisfy the requirement, but future changes that add awaits before guard acquisition should re-check ordering guarantees. This is branch-local review evidence; final main-branch approval/close belongs to merge-completion. --- ## Review: approve Main-branch review/merge-completion approval. Verified before merge: - Branch-local reviewer approved with no blockers. - Merge target matched branch `serialize-file-mutations` / worktree `.worktree/serialize-file-mutations` and commit `40130143`. - Implementation is limited to `crates/tools`; Worker-wide scheduler semantics were not changed. Merged: - `git merge --no-ff serialize-file-mutations -m "merge: serialize file mutations"` - Merge commit: `29960c15 merge: serialize file mutations` Post-merge validation: - `cargo fmt --check` passed. - `git diff --check` passed. - `cargo test -p tools --lib` passed (99 passed). - `cargo check -p tools` passed. - `target/debug/yoi ticket doctor` passed. - typed `TicketDoctor` reported 0 errors and 3 pre-existing diagnostics. - `nix build .#yoi` passed. Result: approve. --- ## State changed Merged branch `serialize-file-mutations` with merge commit `29960c15`; branch-local review approved and post-merge validation passed (`cargo fmt --check`, `git diff --check`, `cargo test -p tools --lib`, `cargo check -p tools`, `target/debug/yoi ticket doctor`, `nix build .#yoi`). --- ## State changed Ticket を closed にしました。 --- ## 完了 完了しました。 実施内容: - `Tracker` に `Write` / `Edit` 共有の per-target-file mutation guard を追加しました。 - `Write` と `Edit` は read/verify/write/record の critical section を同一ファイル単位で直列化します。 - Worker/provider の parallel tool execution は維持し、Worker-wide scheduler は導入していません。 - guard key は canonical target / canonical parent / lexical fallback で同一ファイル相当を寄せ、異なるファイルは別 mutex で扱います。 - `ToolExecutionContext` の `batch_id` / `call_index` は guard acquisition の diagnostics/correlation に使っています。 - same-file write→edit ordering、failed mutation release、equivalent path guard、different-file non-blocking の tests を追加しました。 Merge: - Branch: `serialize-file-mutations` - Merge commit: `29960c15 merge: serialize file mutations` 確認: - Branch-local reviewer `reviewer-serialize-file-mutations` が approve。 - `cargo fmt --check` passed。 - `git diff --check` passed。 - `cargo test -p tools --lib` passed（99 passed）。 - `cargo check -p tools` passed。 - `target/debug/yoi ticket doctor` passed。 - typed `TicketDoctor` は 0 errors / 3 pre-existing diagnostics。 - `nix build .#yoi` passed。 残作業: - なし。将来 `Write` / `Edit` が guard acquisition 前に await を増やす場合は、同一 response 内の call order 保証を再確認してください。 ---
