Tier	Domain	Status	Canonical IDs	Chapter	Scaffold
T0	Primordial	defined	AX-001–AX-004	01_FOUNDATIONS	P-01 Foundations (T0–T1)
T1	Ontological	pending	AX-005–AX-017	01_FOUNDATIONS	P-01 Foundations (T0–T1)

T5	Material	pending	AX-113–AX-122	05_MATTER	P-05 Material (T5)
T6	Relational	locked	AX-123–AX-137	06_DYNAMICS	P-06 Relational (T6)
T7	Ten Laws + Master Equation	missing	AX-138–AX-175 (reserved)	07_MASTER	P-07 Ten Laws & Master Equation (T7)
T8	Validation	missing	AX-176–AX-190	07_MASTER	P-08 Validation (T8)

You previously tracked to AX-188, but the spine now reserves through AX-190 for validation protocols.
If AX-148 is the Master Equation anchor, keep AX-138–AX-175 as the full “equations/laws” band and only later decide sub-ranges.
