The engine, the escrow and the wire were all in place; nothing had a browser on
the end of it. This is that end: a lobby, a table, and the five endpoints between
them.
The browser holds no game. It sends intents and gets back a view — the cards it
is entitled to see, and the script of how they arrived, one event per card off
the shoe. The dealer's hole card is not in the payload at all until the reveal,
because a field the client is told to ignore is a field somebody reads in
devtools. The shoe lives in game_live_hands, which also means a redeploy
mid-hand no longer costs a player their stake: the hand is still there when they
come back.
The money is ordered so nothing can be spent twice. The stake leaves the stack in
the same statement that checks it exists, before a card is dealt. Every new hand
is seated with a plain INSERT, so a double-clicked Deal is decided by the primary
key rather than by a read that raced — it loses, gets its chips back, and the
hand in progress is untouched. A double takes its raise up front and hands it
straight back if the engine refuses the move.
Cards are dealt rather than swapped in — they fly out of the shoe and turn over,
which was a requirement and not a flourish. The faces and the chips are still
plain; that's next.
A euro is either in gogobee's balances or in Pete's chip escrow, never both. It
crosses only via a game_escrow row whose guid is the same idempotency key gogobee
hands to DebitIdem/CreditIdem, so a claim whose ack is lost on the wire can be
retried without the player paying twice.
The border exists because gogobee has no inbound API and isn't getting one, so it
polls. A bet that round-tripped through a poll loop would take seconds to be
dealt. Instead the loop runs twice per session — buy in, cash out — and every hand
between them plays against chips held here, with no economy call in the hot path.
Two rules do most of the work. Chips appear only when gogobee confirms it took the
euros, so a buy-in can't mint money out of a pending request. Chips are destroyed
the moment a cash-out opens, so a player can't bet chips whose euros are already
in flight — and if the credit fails, they come back rather than evaporating.
Also: the €10k table cap counts in-flight buy-ins, so it can't be cleared by
firing several at once; a reaper cashes out anyone idle for 30 minutes, because
chips in an abandoned session are euros in limbo; and every hand is logged with
its seed, so a disputed hand gets answered with a re-deal instead of an apology.
