Task 266: Ship Kestrel Report Quality Review

Status: DONE

Priority: MEDIUM

Objective

Conduct a draft review of the ship-kestrel summary report (ケストレル号総合仕様分析) using an external agent with fresh context. This is one of the most content-dense summary pages, covering ship specifications, mass analysis, propellant budget, nozzle life, and mass timeline visualization.

Per CLAUDE.md: "Periodically have other Claude Code sessions or Codex review reports for readability/clarity."

Review Findings & Fixes

External agent review identified 7 issues (2 HIGH, 2 MEDIUM, 3 LOW):

HIGH severity (fixed):

Mass timeline chart x-axis used obsolete 455-day EP2 transit — Enceladus arrival was at day 458 instead of day 93. Recalculated all x-axis data points using corrected 87-day EP2 transit.
Total ΔV cited as ~31,500 km/s — Cross-episode report gives 36,156 km/s. Updated text and recalculated mass ratio (25→40, propellant fraction 96%→97.5%).

MEDIUM severity (fixed):

EP3 acceleration in G-force table showed 2.21g — This was the 452.5t (mass boundary) value, not the 300t value. Corrected to 3.33g (same as EP1, since both use 9.8 MN at 300t). All derived compensation values also corrected.
Nozzle margin rounded as 0.8% — ep05 report uses 0.78%. Aligned to 0.78% across all 3 occurrences for cross-report consistency.

LOW severity (fixed):

65% cruise description misleading — Clarified that 65% is initial launch power in EP1, becomes damage ceiling from EP4 onward.
「弾道遷移」inaccurate — Changed to 「トリム推力のみの遷移（約87日）」since EP2 uses 3 days of trim thrust.
EP5 mass boundary lacks context — Added clarification that 8.3 days is theoretical direct brachistochrone; actual route is 507h.

Validation tests added:

Total ΔV consistency (36,156 km/s, not 31,500)
Mass timeline x-axis uses corrected EP2 transit
Nozzle margin precision (0.78%)
3 new tests → total TS tests: 2,044
