Seeded a table that looks like a real game — "Mike from work", "Jean-Philippe", stacks from $12 to $3,200,000 — and measured what the layout does with it. ".00" was costing a third of a seat puck Every amount rendered with two forced decimal places. Measured, the trailing ".00" is ~22px, against the 64px a seat puck has to show a stack in. So "$1,250,000.00" needed 102px of a 64px box — and because a number has no spaces to break on, it neither wrapped nor ellipsised. It drew straight out over the seat next to it. Money now shows cents only when there are cents. A chip game deals in whole numbers nearly all the time, and "$12" says exactly what "$12.00" said in half the width. A quarter-blind game is untouched: $0.25, $12.50 and $0.75 pots all still read as before, checked against a 25c/50c table. That alone took "$1,250,000.00" down to "$1,250,000" — 102px to 80px, still wider than the 64px puck. The remaining overflow is handled by stepping the font down on long amounts, which keeps every digit. Abbreviating to "$1.25M" would have fit more comfortably and was the obvious move, but a dealer reading a rounded stack off the felt is a worse failure than a small one, and the exact figure is the entire point of the tool. Measured after: every stack now paints inside its own puck, nothing spills onto a neighbour. Because Money.format is the single formatter all 47 call sites go through, this lands on the seat pucks, action bar, pot breakdown, seat menu, standings and history at once — the payoff from consolidating it earlier. The CSV export couldn't be added up The file exists so a house manager or a disputed chip count has something that outlives the tab, and every money column in it was written as text: "$1,250,000.00". The commas were quoted correctly so the file always parsed — it just imported as strings, so the one thing anyone opens it to do, total a column, needed every cell cleaned first. Money columns now go in as bare numbers (1250000.00) with no symbol and no separators. The columns meant for humans stay human: names are still names, payouts still read "Alexandra: $1,250,000", and a name with a comma in it is still quoted. 12 new tests (88 total, all passing), including the case that would be ruined by dropping cents unconditionally, and a proper quote-aware CSV parser to check every money cell parses as a number. Re-ran the occlusion sweep from the previous round at 9 seats, 10 seats and tournament stacks: still clean, no regression from the font changes.

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.

1000 randomised hands per property (see below) |
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.
