Go Defensive Coding

Go has no exceptions and no null-safety in the type system. Every trap below compiles cleanly, passes review, and fails in production.

Detailed reference material, loaded on demand:

• references/nil-and-aliasing.md — the full typed-nil rules, slice aliasing scenarios, and memory retention.
• references/numeric-safety.md — conversion range checks, overflow detection, float and time comparison.
• references/copies-and-lifecycle.md — copylocks/noCopy, defer in loops, checking deferred Close errors, usable zero values.

Read a reference file only when the section below is not enough.
