// Benchmarks for the encoding primitives in encode.go.
// Per AX-11 — hex + base64 are on every fingerprint emit, every API
// auth-header build, every model-hash compare, every keys.Pack write.
// The wrappers are encoding/{hex,base64} passthroughs; the bench
// harness gates the contract so a Core reroute can't slow them silently.
//
// Run:    go test -bench='BenchmarkEncode' -benchmem -run='^$' .
