A.16.1:20 - Witness and Carrier Triage
A.16.1:20.1 - Witness priority rule
Not all witnesses play the same role. Authors should distinguish the witness that anchors the cue nucleus from secondary witnesses that only enrich or corroborate it. Without that distinction, cue packs become hard to carry into B.4.1 route publication because everything in the pack starts looking equally load-bearing.
A.16.1:20.2 - Carrier overload boundary
A cue pack may cite traces, embodiment, model-state refs, or document fragments, but it should not absorb their full carrier semantics. When carrier analysis itself becomes central, use A.7 or the applicable carrier pattern instead of embedding that analysis into the pack.
A.16.1:20.3 - Early directional plurality rule
Plural lane candidates or plural route-candidate hints are not a flaw. If the same cue nucleus points toward several downstream patterns, keep that plurality visible through B.4.1 route publication, which makes the live routes and any selected route explicit. The error is not plurality; the error is hiding plurality under a single convenient gloss.
