Error Handling And Logging

Explicit error returns, error wrapping, structured logging (slog, zap/zerolog).

Why we need this / what value this brings

Go's explicit-error-return philosophy forces error handling to be visible at every call site — a deliberate design tradeoff.

When to use this

Any function that can fail — decide early whether to wrap, log, or propagate.

How to use or implement this

log/slog (stdlib, 1.21+) for structured logging, wrap errors with context using fmt.Errorf(%w).
