The prior pass swung too far: it answered "does running both give diversity?"
with a flat "No, both are Module-LWE." That under-credits the real security.
Accurate, layered claim now installed in design-decisions / README / SUBMISSION /
nist-mptc-category:
- Pulsar and Corona are distinct SCHEMES at different PARAMETER regimes
(Pulsar = FIPS-204 ML-DSA deterministic FS-with-aborts, q=8380417; Corona =
Ringtail/Raccoon masked threshold, q=0x1000000004A01, params tuned for
threshold). In AND-mode an adversary must forge BOTH; a cryptanalytic,
parameter-specific, or implementation flaw in one does not transfer — the pair
is strictly stronger than either leg alone ("both have to be cracked").
- What it is NOT: hardness-ASSUMPTION diversity. Both rest on Module-LWE/SIS, so a
fundamental Module-LWE break threatens both lattice legs; assumption-disjoint
diversity is the hash-based Magnetar (SLH-DSA) leg.
