A.16.1:16.2 - Route-candidate hints are optional, not forbidden

A cue pack is not an archive of low-articulation cues, but it also need not wait until route-candidate hints are fully articulate. If route-candidate hints are already visible, publish them. If they are not yet visible, publication may still be admissible when the cue nucleus, grounding, and preservation rationale make clear why the cue should not be lost.
