Task 207: Episode↔Summary Analysis Consistency Tests

Status: DONE (completed 2026-02-28)

Priority: HIGH

Objective

Create automated tests that detect inconsistencies between per-episode analysis and summary reports.

Problem

• cross-episode-analysis.ts uses hardcoded EPISODE_SUMMARIES[] that can drift from episode calculations
• EP03 mass boundary: summary says 452t, episode says 452.5t (precision loss)
• No CI check validates cross-report consistency
• When episode calculations change, summary reports silently become stale

Scope

1. Cross-validation test: Compare EPISODE_SUMMARIES[] against analyzeEpisodeX() outputs
2. MDX consistency check: Parse episode MDX computedDeltaV, maxFeasibleMassT and verify against summary references
3. Narrative value check: Extract numerical claims from summary MDX prose and verify against source data
4. Fix existing discrepancies: EP03 massBoundaryT 452 → 452.5
5. CI integration: Run consistency checks as part of npm test

Key Files

• ts/src/cross-episode-analysis.ts (hardcoded EPISODE_SUMMARIES[])
• ts/src/cross-episode-analysis.test.ts (existing structure tests)
• ts/src/analysis-reproduction.test.ts (per-episode pinned values)
• reports/data/summary/cross-episode.md
• reports/data/summary/ship-kestrel.md

Dependencies

• Task 206 may change EP02 parameters that affect cross-episode consistency
