Go Context Usage

Compatibility: context has been in the standard library since Go 1.7.

Resource Routing

• references/PATTERNS.md - Read when deriving contexts, checking cancellation, handling HTTP request contexts, or using typed context-value keys.

Context as First Parameter

Functions that use a Context should accept it as their first parameter:

func F(ctx context.Context, /* other arguments */) error
func ProcessRequest(ctx context.Context, req *Request) (*Response, error)

This is a strong convention in Go that makes context flow visible and consistent across codebases.
