Measured every overlay in the tool before touching anything. For a dealer running this on a laptop, all six were broken in the same three ways. - focus never moved into the dialog: 0 of 5 measured - Tab walked straight out of the dialog into the page behind the scrim: 5 of 5 - Escape did nothing: only the rulings sheet handled it, 1 of 5 - the pot wizard — the dialog that pays people — had no role and no accessible name at all So opening the pot wizard left focus on the button behind it, tabbing wandered through a page nobody can see or click, and there was no way back out except the mouse. One implementation, not six The overlays are opened and closed by five different modules, which is why they each missed the same things. Rather than patch this into all of them, modal.js watches the `hidden` attribute they already toggle: focus moves to the first real control on open, Tab and Shift-Tab wrap inside the dialog, Escape closes it, and focus returns to whatever opened it. `aria-modal` is set while open and removed on close. An overlay added later gets all of it without anyone remembering to wire it up, which is the failure being fixed. Escape presses the dialog's own cancel button rather than just hiding the overlay, so the confirm dialog still resolves its promise — verified: Escape resolves it to false rather than leaving an await hanging forever. Shortcuts.overlayOpen() had the same shape of bug, listing the six overlay ids by hand. It asks the document now, so a sheet added later can't quietly start letting "f" fold the table behind it. Focus you can see Three focus rules existed for the whole stylesheet, so tabbing relied on the browser default ring, which on these dark custom-painted controls is close to invisible. `:focus-visible` keeps it to keyboard use so a dealer tapping Fold isn't left with a ring on it. That surfaced something small: `.holdemBtn` used `transition: all`, so the new outline faded in over 150ms and the ring lagged a step behind the Tab key. The transition names its properties now. Measured after: 16 of 16 tab stops show a ring immediately, and the press state from before still animates. Also - a mistyped negative stack read back as negative, and flowed into putIn() where Math.min(amount, -50) moves a negative amount and adds chips to the table. Clamped at zero. - accessible names for the chip colour, chip value and notes fields, which had none 11 new tests (99 total), covering negative stacks, negative and unreadable blinds, blinds nobody can cover, and a save that comes back corrupt, truncated, or from before a field existed. Playwright: all five overlays re-measured — focus moves in 5/5, Tab and Shift-Tab trapped 5/5, Escape closes 5/5, focus restored 5/5, role and aria-modal present 5/5. Shortcuts still fire when no dialog is open and are still blocked when one is. Touch guarantees from the earlier round unchanged: 0 of 49 controls on touch-action auto, 0 tap-highlighted.

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.
What's covered
| File | Covers |
|---|---|
potCalculator.test.js |
Main and side pots, dead money, uncalled bets, odd-cent distribution |
betting.test.js |
Blinds, street completion, raises reopening the action, all-in run-outs |
state.test.js |
Button rotation, which seats post blinds, session standings |
splitCalculator.test.js |
Chopped pots, odd chips, unmakeable denominations |
invariants.test.js |
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.
