Observable Validation
Test Suite Results
Every claim is gated by a deterministic test. The public artifacts: the adversarial gate (140/140 caught on its own synthetic test corpus, n=220, written for the repo) and the 47,312-record COBOL probe. Clone and re-run bit-for-bit.

Suite Breakdown
COBOL Payroll Replay (synthetic)Legacy
✓ PASS
Bit-for-bit identical replay across 47,312 synthetic records, fixed seed.
LLM Adversarial Validation GateSecurity
✓ PASS
140/140 adversarial caught, 0/80 synthetic benign prompts blocked, on its own synthetic test corpus (n=220, written for the repo). CI green.
Every suite above: PASS. One RED blocks the ship.
A synthetic $40,812.81 loss the public probe surfaces in seconds. The real cost compounds for as long as an equivalent failure class runs undetected.
