Player identity is now Ed25519 and ML-DSA-65 (NIST FIPS 204) together,
both signatures required. An attacker must break lattice assumptions and
elliptic curves, not either one — which covers both the quantum threat to
Ed25519 and the possibility that a 2024 lattice standard does not hold.
Signatures are domain-separated to this application so one captured from
another ML-DSA protocol cannot be replayed.
Licensed AGPL-3.0: a fork stood up as a service must publish its changes,
which is what keeps a provably-fair platform honest.

Round length is now bounded: the multiplier follows a hyperbolic curve
diverging at 60s, replacing an exponential one where a 275x crash point
produced a two-and-a-half minute round.
Fixes seed reveal, which silently failed every round because pgx cannot
encode a fixed-size byte array as bytea.

The Lightning bridge is modelled as the boundary with the outside
world and is the one account permitted to go negative; its negative
balance is exactly what is owed to players inside the system. All
other accounts are floored at zero by both the application and a
database trigger.
