Task 022: Build Test Fix & Report Readability Review

Status: DONE

Objective

1. Fix the 3 pre-existing build test failures (fixture naming mismatch)
2. Conduct a Codex-assisted report readability review (per CLAUDE.md directive)

Progress

• [x] Identified root cause: build.test.ts fixtures used ep-001.json but discoverEpisodes regex expects ep\d+\.json (i.e. ep01.json)
• [x] Fixed test fixtures to use production naming convention (ep01.json, ep02.json)
• [x] All 428 TS tests + 52 Rust tests passing (0 failures)
• [x] Codex-assisted readability review completed
• [x] Applied Codex review findings to reports

Build Test Fix

The test fixtures in build.test.ts (lines 47, 62, 63, 184) wrote files named ep-001.json and ep-002.json, but the production regex /^ep\d+\.json$/ only matches ep01.json style. The production data files in reports/data/episodes/ already use the correct format. Fix was straightforward: update test fixtures to match.

Codex Report Review Findings & Actions

Applied Improvements

1. ASR error corrected: ep02-quote-03 "洗面の中心線" → "遷移面の中心線" (confirmed ASR misrecognition)
2. Japanese phrasing improved:

- ep01: "条件次第では成立しうる" → "質量についての前提条件を置けば成立しうる" (more specific)

- ep02: "マージンが約0.53 km/s" → "速度余裕は約0.53 km/s" (more natural Japanese)

1. Precision descriptions improved (Codex recommendation: show difference first, then relative error):

- ep03: "比率1.002" → "差33,613 km、相対誤差約0.2%"

- ep04: "99.5%一致" → "差0.3°（相対誤差約0.5%）"

- cross-episode summary: same improvements applied

1. Cross-episode conclusion balanced: Added caveats about model limitations (二体問題一次近似), ASR uncertainty, and remaining unknowns per Codex advice

Noted for Future Tasks (not applied this session)

• Fixed template structure (前提→計算モデル→主要結果→感度分析→限界) — would require template.ts changes
• 3-line summary at top of each analysis — structural change
• Confidence labels (高/中/低) per claim — data schema change
• Separate ASR quotes from verified quotes — requires attribution pipeline completion (Task 009)
