This is where a *build cache* is helpful.

The build cache stores previous build results and restores them when needed.
It prevents the redundant work and cost of executing time-consuming and expensive processes.

When the build cache has been used to repopulate the local directory, the tasks are marked as `FROM-CACHE`:

### New unique package

The new [unique] package provides facilities for
canonicalizing values (like "interning" or "hash-consing").

Any value of comparable type may be canonicalized with the new
`Make[T]` function, which produces a reference to a canonical copy of
the value in the form of a `Handle[T]`.
Two `Handle[T]` are equal if and only if the values used to produce the
handles are equal, allowing programs to deduplicate values and reduce

		// NOTE: another reasonable approach here might be to return a
		// randomized slice if we encounter an error, which would break the
		// connection, but avoid panicking. This would perhaps be safer but
		// significantly more confusing to users.
		panic(fmt.Errorf("failed to construct HKDF label: %s", err))
	}
	out := make([]byte, length)
	n, err := hkdf.Expand(c.hash.New, secret, hkdfLabelBytes).Read(out)
	if err != nil || n != length {

	nonce := s.seqNum.bytes()[16-s.aead.NonceSize():]
	for i := range s.baseNonce {
		nonce[i] ^= s.baseNonce[i]
	}
	// Message limit is, according to the RFC, 2^95+1, which
	// is somewhat confusing, but we do as we're told.
	if s.seqNum.bitLen() >= (s.aead.NonceSize()*8)-1 {
		panic("message limit reached")
	}
	s.seqNum = s.seqNum.addOne()
	return nonce
