Round-by-round evidence

Every attempt and point movement

Round order comes from round_index. Replay order comes only from domain_events.seq—not timestamps or UUIDs.

Account opening

Initial ledger evidence

Deterministic sessions receive an isolated platform grant. Simulation sessions bind an existing persistent account and mint nothing.

No session-specific opening entry. This session uses the persistent account.

Canonical ordering

Domain event stream

Every row is shown in authoritative seq order.
