* Standalone Adversarial Stress-Test Script for Milestone M2
|
|
* Diablo II Web DRLG Engine: Organic Geometry & Fractional Jitter Profiler
|
|
*
|
|
* Requirements:
|
|
* 1. Stress-test Act 2 Oasis and Act 5 Frozen Lake radial lobe perturbations across 100+ random seeds and phase variations:
|
|
* - Numerically compute P^2 / A for continuous polar contour and discrete rasterized tile cells.
|
|
* - Assert P^2 / A > 4*pi * 1.15 holds 100% of the time (zero violations).
|
|
* 2. Stress-test jitterFrac: sample 10,000 draws and assert all values strictly lie in [base - delta, base + delta].
|
|
* 3. Verify Act 1 baseline hashes in tests/wilderness-seed-sensitivity.test.ts remain 100% bit-identical.
|
|
* 4. Verify Act 4 Lava Fissure flood-fill reachability >= 90%.
|
|
* 5. Verify Act 5 Transverse Barricade palisade orientation and choke-point gate clearance.
|
|
*
|
|
* Archetype: EMPIRICAL CHALLENGER
