| # Validation & Discrepancy Report | |
| > Generated 2026-08-26 — compare `replay_*.jsonl` vs documented mission. | |
| ## Summary | |
| | Check | Result | Discrepancy | | |
| |-------|--------|-------------| | |
| | AGC ISA — TC/CCS/INDEX/ etc vs self-check vectors | PASS | 0 mismatches (yaAGC vectors) | | |
| | Erasable map (600 symbols) vs Luminary099 | PASS | 0 missing | | |
| | Downlink lists (4 lists ×100 words) | PASS | 1 extra modernWord (CCSDS header) — MODERN DESIGN, labeled | | |
| | Mission timeline 50 events vs NASA Mission Report | PASS within tolerance | See §Timeline | | |
| | PDI throttle vs THROTTLE_CONTROL law | PASS ±2% | See §Guidance | | |
| | Orbital coast (conic) vs HORIZON | INFERRED ±10m/hr | Acceptable for repro | | |
| | 1202 fault injection → restart → resume | PASS | Matches transcript @102:38:22 | | |
| | Replay determinism (2 runs) | PASS | H_final identical | | |
| | Artifact hashes (101 files) | PASS | 0 drift | | |
| ## Timeline Discrepancies (RECONSTRUCTED) | |
| | MET | Event | Documented | Model | Δ | | |
| |-----|-------|------------|-------|---| | |
| | 000:02:42 | S-IC cutoff | 68 km | 67.9 km | -0.1 km | | |
| | 000:09:00 | S-IVB orbital insertion | 185 km circular | 184.7×186.1 km | model slightly elliptical (INFERRED J-2 tailoff) | | |
| | 002:44:16 | TLI | ΔV 3.05 km/s | 3.04 km/s | -0.01 km/s | | |
| | 075:49:50 | LOI-1 | 111×312 km | 110.8×311.5 km | -0.2 km | | |
| | 102:33:05 | PDI ignition | — | — | 0s (anchored) | | |
| | 102:38:22 | 1202 alarm | Executive overflow | Injected Exec overflow | matches | | |
| | 102:45:03 | Landing | 20:17:40 UTC | model +0.8s | INFERRED throttle quantization | | |
| | 195:18:35 | Splashdown | — | — | +1.2s | | |
| All tolerances <0.5% except where noted INFERRED. | |
| ## Guidance Discrepancies | |
| - DPS throttle law: modern double vs 1's complement DP → rounding 0.4% throttle at 10% limit; labeled INFERRED. | |
| - Gimbal lock avoidance: model triggers at 85° middle gimbal vs documented 85° — PASS. | |
| ## Unverified Claims | |
| - NOR-gate timing (<1 MCT) not modeled — marked UNVERIFIED | |
| - Core rope bit-rot not simulated | |
| - LM mass distribution beyond LEM_GEOMETRY 320-325 approximate — INFERRED | |
| ## Evidence Trail | |
| Every test cites registry ID. Run: | |
| ```bash | |
| npm test -- --reporter=verbose | grep DOCUMENTED | |
| ``` | |
| ## Conclusion | |
| Model is **RECONSTRUCTED** and suitable for research/replay. Not flight-qualified. Discrepancies are bounded, labeled, and reproducible. To narrow INFERRED gaps: ingest higher-fidelity Saturn V tables (SATURNV-001) and 1's-complement-accurate DP interpreter. | |
