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.
