✓ Provably fair — the seed was committed on-chain before play, the exact step stream was signed by the player's key, and every roll, decision, and payout below is re-derived from public inputs and matches the on-chain settlement.

Proof of randomness
✓1.The seed was committed before you played
The commitment keccak256(serverSeed) was fixed on-chain in the open transaction at block 59671291, before any step was played. The seed revealed at close must hash back to that commitment — since keccak256 has no known way to find a second preimage, the house had exactly one seed it could ever reveal, chosen before it saw a single one of your bets.

✓ matches the commitment
✓2.You signed the exact stream that settled
Each step, your session key signed DrawCommit(channelId, steps, root) — a running hash-chain over every round you entered, every decision you took, and every reveal you requested, signed before the outcome was shown. The close can only settle a stream and count carrying your signature: the house can't add, drop, or reorder a single step.

✓3.The stream hash-chain checks out
Re-folding the submitted stream — root_t = keccak256(root_(t−1), t, …) over each round's (stake, game), each decision's choice, and each reveal — must reproduce the root you signed, pinning the exact sequence to your signature.

✓ The recomputed net, wagered total, and step count match the on-chain settlement exactly.
✓5.Every round respected the committed caps
The channel committed hard walls before play: no stake above the budget of $170.88, and no single round whose worst-case win exceeds the committed per-round cap of $170.17 against its own game's maximum multiplier. Every round in the stream was re-checked against both — the same integer comparison the contract itself enforces. All rounds fit.
Games (on-chain catalog) chain
Each game is a value tree stored on-chain and validated by the contract when it was sealed — the edge under optimal play is enforced inside a fixed band, so no game referenced here can be unfair in either direction. The payouts above were walked from these exact trees, reconstructed from the chain's packed words.
