TigerStyle: Zig Coding Guidelines

Distilled from TigerBeetle's TIGER_STYLE.md. Design goal priority: Safety > Performance > Developer Experience.

1. Safety

Control Flow

• Use only simple, explicit control flow. No recursion unless provably bounded.

• Split compound conditions into nested if/else branches — ensure both the positive and negative spaces are handled or asserted.

• State invariants positively:

  // preferred
  if (index < length) { ... } else { ... }
