In `@docs/takt-step-timings.md`:
- Around line 74-79: The sentence mentioning “baseline 203s” must distinguish
the ADR-056 acceptance-criteria reference value from the table’s measured
baseline averages of 164.4s/164s. Revise that phrase to explicitly identify 203s
as the ADR-056 target/reference baseline, preserving the existing comparison and
qualification about raw versus normalized timings.
In `@docs/todo-summary.md`:
- Line 8: Update the date in the “推奨実行順序サマリー” heading to the actual update date,
2026-07-18, rather than the future date currently shown.

ConvertTo-Utc まで含む範囲へ拡張し、Get-Content に -ErrorAction Stop
を指定してください。読み取り・JSON解析・日時変換のいずれかが失敗した場合は、その run だけを continue

…llow-up todo (#295/#296 post-merge feedback) PR #295/#296 の post-merge feedback 採用候補を反映。(1) analyze-takt-timings.ps1 L47 の ConvertFrom-Json を try/catch で保護し、crashed/in-progress run の truncated meta.json 1 件で集計ループ全体が中断しないよう skip (L63 の phase 行 parse と同流儀。CodeRabbit の startTime null ガードが塞げなかった JSON 自体の破損を補完)。(2) takt-step-timings.md の「正規化前提」と述べつつ未正規化 avg を 150s と直接『未達』断定していた矛盾を、diff サイズ交絡を明記し最終判定を R4/ADR-056 に委ねる記述に修正。 あわせて todo 起案: 順位327 (多段コミットの ADR/observability 更新チェックリストを dev-conventions に、Tier3)、順位328 (post-merge feedback が成功後に context.json を残し次マージの feedback を誤 bail させる cleanup gap、#296 マージで実観測、Tier1)。 検証: 正常出力不変 (24 run 203.4s)、truncated meta.json を skip してクラッシュしないことを実機確認。docs-lint / markdownlint OK。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
analyze-takt-timings.ps1のConvertFrom-Json(L47) を try/catch で保護 → crashed/in-progress run の破損 (truncated)meta.json1 件で集計ループ全体が中断しないよう skip する (L63 の phase 行 parse と同流儀)docs/takt-step-timings.mdの「run 間比較は diff サイズ正規化が前提」と述べつつ未正規化 avg を 150s と直接「未達」断定していた矛盾を解消 (diff 交絡を明記し、最終判定を R4/ADR-056 に委譲)context.jsonを残し次マージの feedback を誤 bail させる cleanup gap、Tier1)Context
Why: PR #295 / #296 の post-merge feedback が両方とも採用候補と判定した 2 件 + 新規 todo。#295 の CodeRabbit 修正 (
startTimenull ガード) はフィールド欠損は塞いだが、meta.json自体の破損 (crashed run の truncated JSON) はConvertFrom-Jsonが throw して依然クラッシュした (L47 が try/catch 未保護、同ファイル L63 は保護済みで非対称)。doc の矛盾は R4 (ADR-047/056) 採否判定の根拠を誤読させ得た。Trigger:
.claude/feedback-reports/295.mdTier3 #2 /.claude/feedback-reports/296.mdTier2 #1・Tier3 #1。Validation
pnpm pushpre-push review: verdict=APPROVE (2026-07-19)。refute 撤去後の非 refutepre-push-reviewで完走 (1 iteration, 134s) = 撤去の実 push 検証も兼ねる。meta.jsonを仕込んで skip・非クラッシュを実機確認。正常出力は不変 (24 run 203.4s)。pnpm lint:docs/ markdownlint OK。References
