### Default CA Flow through istio-agent

![CA Flow](docs/ca.svg)

A single SDS request from Envoy goes through a few different layers in istio-agent.

// init bool says whether this is a valid gmp value.
// doinit initializes z.i if it needs it.  This is not inherent
// to FFI, just a mismatch between Go's convention of
// making zero values useful and gmp's decision not to.
func (z *Int) doinit() {
	if z.init {
		return
	}
	z.init = true
	C.mpz_init(&z.i[0])
}

// Bytes returns z's representation as a big-endian byte array.
func (z *Int) Bytes() []byte {

 * and the last 7 bits from this byte.

 * The end of the range is not encoded, but can be inferred by looking at the start of the range
 * that follows.

 * b1

 * This is either a mapping decision or the length of the mapped output, according to this table:

 *  0..63 : Length of the UTF-16 sequence that this range maps to. The offset is b2b3.

Given these constraints, we cannot always follow best practices.  This ADR proposes the way we should handle the use of Provider APIs in the gradle/gradle codebase.

### Types of properties that should not use lazy types

The guidelines below do not apply to all properties. There are cases where the lazy types should not be used:

#### Non-calculated values
