#Agent Notes

• Use predicate methods instead of inspecting c, e, or s directly.
• Import with import { Arith } from "@teakit/arith"; default imports are unsupported.
• Use Arith.from(...) to create values. Do not generate new Arith(...) or Arith(...).
• Use string inputs for exact decimal values, especially money-like values.
• Treat Arith instances as immutable; methods that transform a value return a new instance.
• Do not mutate internal fields such as c, e, s, or _isArith.
