Went looking at dealer procedure again and ended up checking the rule home games argue about longest. The tool had it wrong. Blinds 1/2. Seat 4 raises to 10 — a full raise of 8. Seat 1 calls. Seat 2 is all-in for 13: three more, where a full raise would need eight. Under TDA rule 44 that does not reopen the betting to anyone who has already acted; they owe the extra three or they fold. Seat 1 and seat 4 were both being handed another go. Two things were wrong in raiseTo. Any increase at all reset hasActed for every live player, so a short shove gave the whole table another chance to raise. And lastRaiseSize was overwritten with the short amount, so the next legal raise was computed off 3 instead of 8 and came out too small — a second, quieter error that only shows up when somebody then tries to raise. Both now key off whether the increase was actually a full raise. A player who had not yet acted keeps full rights, which falls out naturally because their hasActed is already false — that distinction is the part of the rule people get wrong in the other direction. Everyone still owes the difference: isStreetComplete already asks anyone with chips left to call, so the short all-in is answered without being re-raiseable. The rulings sheet now covers what the tool does for you It had three entries. A dealer challenged on a payout couldn't look up why the tool did what it did, even for the rules it enforces automatically. Added the short all-in rule above, uncalled chips coming back rather than being announced as a side pot, and the odd chip in a chopped pot going to the first player left of the button — all three are things this tool already decides silently, and all three are worth being able to point at when somebody objects. 10 tests (137 total): already-acted players aren't reopened but still owe the difference, a player yet to act keeps full rights, the minimum raise isn't shrunk, calling it ends the street, no chips are created, and — the other half of the rule — a full-sized all-in, an ordinary raise, a raise exactly matching the last one, and a full-sized opening bet all still reopen everyone. Validated through the real action bar: after the short shove, lastRaiseSize stays 8 and the player who had already called stays settled, while the two who hadn't acted keep their turn. The longer rulings sheet still fits a phone, scrolls, traps focus and closes on Escape.

Hold'em dealer tests
Unit tests for the money logic behind /Casino/TexasHoldem — the betting engine, the
side-pot calculator, the split calculator and the table state.
node --test tests/holdem/*.test.js
No install step, no package.json, no dependencies. The browser modules are plain
script-tag files that each end with a module.exports guard, so Node can require them
as-is; load.js puts them on globalThis under the same names they use to find each
other in the page, in the load order from TexasHoldem.cshtml.

Why the randomised suite exists
Every correctness bug found in this tool so far has been shape-dependent: blinds posted to empty chairs, the button skipping past players, heads-up acting out of order, an overbet announced as a side pot. None of them show up on a full six-handed table with equal stacks, which is the table anyone writes a fixed example for.
invariants.test.js deals a thousand hands across random seat counts, random empty
chairs, random stack depths and random dealer input, and checks the things a dealer
would notice being wrong:
- chips are never created or destroyed during play
- the pot breakdown plus the uncalled returns always equal the money that went in
- paying the pot out settles it to the cent
- once uncalled chips are handed back, nobody is still betting above the whole table
- the button and both blinds always land on players who are actually in the hand
The generator is seeded, so a failure reproduces from the seed printed in the message rather than being a flake to re-run.
