#27

What to build

Two places where the craps code and the module's own rules comment disagree get
a decision, each behind a test that names the rate chosen.

The Field pays double on both 2 and 12, where the rules comment says 2:1 on 2 and
3:1 on 12. And Don't Pass wins outright on 12, where the comment calls 12 a push
for both sides of the line — the bar-12 every craps table has.

Both are rules choices rather than defects: nothing in the code arbitrates, so
somebody has to. Whichever way each goes, the outcome is a test that states the
rate, so the next reader finds a decision instead of an accident.

The push outcome this needs already exists — #31 puts it in the payout type
without anything yet producing one.

Acceptance criteria

The Field's rate on 12 is decided, and code and rules comment agree
The Field's rate on 2 is decided the same way
Whether Don't Pass pushes or wins on 12 is decided, and code and rules
comment agree
Each decision has a test naming the rate, so a later change to it is a
visible one
A push, if bar-12 becomes one, returns the player's wager untouched and
counts as neither a win nor a loss in their record
The test suite passes and the linter is clean
