Task 506: Cross-Episode Consistency Expansion in analysis-reproduction.test.ts

Status: DONE

Summary

Expanded cross-episode consistency checks in analysis-reproduction.test.ts from 3 tests to 24 tests. Verifies that per-episode analyses use consistent parameters across independently-maintained calculation modules.

Tests Added (21 new)

Constants consistency (5 tests)

Isp: relativistic analysis parameters.ispSeconds == KESTREL.ispS
Speed of light: relativistic parameters.speedOfLightKms == C_KMS
Exhaust velocity: relativistic parameters.exhaustVelocityKms == EXHAUST_VELOCITY_KMS
EP04 damaged thrust == DAMAGED_THRUST_MN (6.37)
EP04 normal thrust == THRUST_MN (9.8)

EP04→EP05 damage linkage (4 tests)

Thrust fraction 0.65 consistent; 48kt accel matches EP04→EP05
Radiation exposure 480 mSv carries from EP04 into EP05 burn budget
EP05 remaining-to-ICRP = limit - current (arithmetic consistency)
EP04 plasmoid shield margin 43% matches EP05 nozzle seriesMargins

Nozzle sensitivity (3 tests)

Plan scenario has positive margin (1560s)
1% burn increase → negative margin (nozzle fails)
5% decrease → largest positive margin (>10000s)

Relativistic cumulative (3 tests)

Cumulative time dilation ≈ sum of per-transfer values
Minutes = seconds / 60 (unit consistency)
EP05 contributes the most time dilation

Oberth effect (3 tests)

Best-case efficiency 0.07% << claimed 3%
Burn saving exceeds 26 min nozzle margin
v_inf 1500 km/s < EP05 peak velocity (conservative assumption)

Full route (3 tests)

Furthest point ~19.2 AU ≈ Uranus semi-major axis
4 route legs
EP04 damaged thrust / mass = EP05 48kt acceleration (parameter chain)

Impact

Catches parameter drift across EP04→EP05 damage linkage, verifies kestrel.ts constants flow through to relativistic analysis, and confirms nozzle sensitivity scenarios bracket the margin correctly.
