Task 038: Enrich Earlier Reports with Later Episode Findings

Status: DONE

Motivation

Human directive: "後の話や後の話の解析から明らかになった事実も、解析に使えるデータないし文脈として既存レポートを追記・清書してよい"

Currently each episode report is written mostly in isolation. But findings from later episodes can inform earlier analyses. For example:

• EP04-05 mass boundary constraints can be cross-referenced with EP01's mass analysis
• EP03's navigation precision can validate EP01-02 trajectory assumptions
• EP05's final route data gives total ΔV budget context for all earlier transfers

Scope

1. Review each episode report for opportunities to add cross-episode context
2. Add references to later findings where they strengthen or nuance earlier analysis
3. Ensure consistency of parameters and assumptions across all reports
4. Clean up and polish existing report text where needed

Completed Work

Approach (Codex-reviewed)

Hybrid A+C+D: Woven text in explanation/summary fields (A), cross-episode source citations (C), and enriched exploration summaries (D). No schema changes beyond adding "cross-episode" to SourceCitation.sourceType.

Changes

1. report-types.ts: Added "cross-episode" to SourceCitation.sourceType union
2. report-data-validation.test.ts: Added "cross-episode" to validSourceTypes

Episode Enrichments

• EP01: Mass boundary cross-ref (EP03 ≤452t confirms EP01 ≤299t), 65% thrust symmetry with EP04, full route distance (35.9 AU), cross-episode source citation
• EP02: EP03 confirms Saturn capture success, 455-day transit confirmed, unknown vessel → EP04 fleet connection, "ギリギリ" design pattern across series
• EP03: EP04 plasmoid encounter as sequel to 25RU approach, mass boundary convergence analysis (mathematical consistency), cross-episode source citation
• EP04: EP01 "嵐の回廊" thematic symmetry, 65%=EP01 cruise thrust source citation, mass boundary convergence summary, EP03 plasmoid foreshadowing
• EP05: All-episode mass estimates context, full route cross-episode source citations (ep01-04), "ギリギリ" pattern compilation

Test Results

• 755 TS tests: all pass
• 79 Rust tests: all pass
• Build: 5 episodes, 24 transfers, 1 summary → dist/

Depends on

• All episode analyses (ep01-ep05)
• Task 037 (planetary positions may affect report content)
