C.2.5:4.2 - Starter anchor set

Anchor	Reading	Typical governance effect
`CD0`	exploratory-open	broad rival space remains live
`CD1`	weakly stabilized	some contrasts are present, but rival routes remain normal
`CD2`	narrowed candidate space	explicit rivals remain, but the field is meaningfully reduced
`CD3`	selected route or framing	one route is chosen, though reopening remains routine
`CD4`	publication- or operation-fixed under guard	changes require named justification
`CD5`	strongly fixed	relaxation requires an explicit `A.16.2` move and governance note
