… diff metadata strip + silent failure baseline cleanup Bundle l 3 サブ変更を bundled で land (順位 129 + 131 + 132、todo-summary.md table 4 行整理含む)。 共通テーマ: cli-push-runner lint-screen stage の堅牢化 + I/O write 関数の silent failure 構造的防止。 順位 132 (Tier 1 / S): cli-push-runner/src/stages/lint_screen.rs に strip_diff_metadata_lines 前処理関数を追加し、similarity index NN% / index <hex> / file mode / rename 系の diff metadata 行を LLM 入力前に決定論的に除去。PR #155-#156 で 5 観測された mistral:7b の magic-number FP を構造的に解消。unit test 7 件 (各 metadata 系列 + content 保持 + substring 誤検出回避)。 順位 130 (prompt 改修 or 前処理 filter のいずれか) を本実装で前処理 filter に確定して supersede、 table から 130 行も削除。 順位 129 (Tier 1 / S): .claude/custom-lint-rules.toml に rule⑩ (no-write-result-discard、 pattern let\s+_\s*=\s+write_\w+\(、extensions=["rs"]、severity=error) を追加。 hooks-post-tool-linter に 8 件 unit test を追加 (positive x3 / negative x4 / dogfood x1)。 dogfood test (deployed_src_rust_passes_no_write_result_discard_rule) は src/**/*.rs を再帰走査して clean baseline を強制。本 PR の completeness criteria に合わせて既存違反 5 件を fix: - cli-pr-monitor/src/stages/poll.rs: 3 箇所の let _ = write_state(...) を if let Err(e) = ... { log_info(...) } に置換 (非 fatal 進行 + 観測可能性回復) - cli-merge-pipeline/src/feedback.rs: FailedMarkerGuard::drop 内の write_failed_marker と feedback::run の write_pending_marker を log 化、後者は write_pending_marker_logged helper に抽出して fn run の 50 行ガイドライン超過を回避 (lint_screen.rs の write_skip_report_logged と同 pattern) 順位 131 (Tier 2 / M): write_skip_report_logged の error path regression test を 3 件追加。 parent が regular file な path に書込を試みて create_dir_all 失敗を確定的に誘発する方式 (Unix/Windows 両方で reliable、追加 dep 不要)。write_skip_report の Err 返却 + write_skip_report_logged の no-panic + writable path success の 3 段で seal、将来 refactor での silent drop 回帰を機械検出。 副次: src/cli-push-runner/Cargo.toml に tempfile dev-dep を追加 (順位 131 test 用)、 todo8.md から 129/130/131/132 detail entry を削除 (Cross-File Reference Lifecycle 整合)。 検証: cargo test 全 workspace pass / pnpm build:all 成功 / 変更 crate 3 つ (cli-push-runner / hooks-post-tool-linter / cli-pr-monitor) で cargo clippy --all-targets -- -D warnings clean。

let _ = write_*swallowed error 検出 custom lint rule (rule⑩、no-write-result-discard) を.claude/custom-lint-rules.tomlに追加 (順位 129)cli-push-runnerlint-screen stage に git diff metadata 行 (similarity index NN%/index <hex>/ file mode / rename) の前処理 strip を追加し、mistral:7b magic-number FP を構造的に解消 (順位 132、順位 130 を supersede)write_skip_report_loggedの error path に regression test 3 件を追加し silent drop への回帰を機械検出 (順位 131)let _ = write_*violations をif let Err(e) = ... { log_*(...) }形式に置換 (cli-pr-monitor poll.rs ×3 + cli-merge-pipeline feedback.rs ×2)、rule⑩ の clean baseline を確立hooks-post-tool-linterに rule⑩ 検証 test を 8 件追加 (positive ×3 / negative ×4 / dogfood scan ×1)、todo-summary.md / todo8.md から 4 entries を整理Context
Why: PR #155-#156 の lint-screen self-dogfood で 2 つの構造的問題が観測された:
write_skip_reportの Result をlet _ =で silent drop していた anti-pattern (BLOCKING 指摘で fix 済だが、再発防止層なし)similarity index 100%の100%を magic-number として FP 検出 (file rename 含む PR で必ず出現するため Frequency Medium)Trigger: PR #155 post-merge-feedback (順位 129/131) + PR #156 post-merge-feedback (順位 132)。順位 130 (PR #155 由来) は順位 132 と root cause 同一のため本 PR で supersede + 削除。
Scope decision: 順位 129 は本来「rule 追加のみ」(Adoption Risk None) を想定していたが、現実の codebase に 5 件の既存違反 (poll.rs ×3 / feedback.rs ×2) があり、completeness criteria (
deployed_src_rust_passes_no_write_result_discard_ruleで baseline 0 件強制) を満たすため fix を同 PR に bundle。silent failure を log 化することで観測可能性も同時に回復するため、scope expansion が justified。write_pending_marker_loggedhelper の抽出はfn runの 50 行ガイドライン超過回避が motivation で、lint_screen.rs のwrite_skip_report_loggedと同 pattern。Validation
