Recommendation
Author one combined T101-STD-001 semantic candidate with internal substandards as T101 dogfood for #450; preserve T101-STD-002/003 lineage and condition final family placement and acceptance on #450 compatibility or an explicit durable variance.
Reasoning
One operative benefits from one precedence and amendment chain without silently establishing Program-wide family precedent.
Alternative + consequence delta
Wait for #450 before authoring, or keep three independent files; waiting blocks useful dogfood while three files create cross-file precedence risk.
Downstream impact
TK001 placement research, TK002 candidate, #450 evidence, SPS lineage, and GATE001 acceptance.
