TECH-DEBT.adoc:261-262 carries CORE-04 as S2 'partial' with NO issue number; CAPABILITY-MATRIX.adoc:134-137. Residual: (1) associated-type substitution in method bodies, (2) where-clause supertraits, (3) coherence checking — without coherence, overlapping impls can resolve arbitrarily (accepts-wrong-program class → T0); (1)/(2) are feature-absence (shippable disclosed → T1/T2 cut decision). Filed to give the ledger row a tracking home. Part of the v1-readiness ledger.
