  • InterestVestingStatusScheme (3) — vested + contingent + defeasible

Hudson §3.5 certainty-of-objects substrate Day-1

  • IRC v Broadway Cottages [1955] Ch 20 — complete-list test for fixed trusts
  • McPhail v Doulton [1971] AC 424 — is-or-is-not test for discretionary trusts (House of Lords landmark)
  • Re Gulbenkian [1968] Ch 126 — predecessor case
  • Saunders v Vautier (1841) 4 Beav 115 — bare-trust beneficiary right-to-call
  • Schmidt v Rosewood [2003] UKPC 26 — beneficiary information rights for discretionary trusts (substrate-correcting DELTA #2)
  • Charitable Trusts Act 2011 + cy-près doctrine

4 Catala rules Phase-5-deferred

  • CertaintyOfObjectsCheck (P-07 + P-08 Lawsky; Hudson §3.5 canonical; branches on interest_kind)
  • BeneficialInterestVestingCheck (P-07; condition-precedent + condition-subsequent)
  • SaundersVVautierEligibilityCheck (P-07; sui-juris + absolutely-entitled)
  • CharitableTrustValidityCheck Phase-1.5+ (P-04 OASIS; Charity Commission)

EW state

  • EW-1 counter stays 0 (Q-039 has 0 c-objections folded inline)
  • EW-4 counter 2→3 (3rd consecutive bold-synthesis on Trusts substrate; reset at Trusts→Assets boundary anticipated)
  • EW-2/EW-3/EW-5 not fired

MQ-009 multi-aspect-class pattern FIRST cascade use

bfo_alignment: 'BFO:0000040 material entity (interest-as-property-right per Hudson §2.4.3)' bfo_secondary_aspect: 'BFO:0000019 quality (claim against trustees)'

Hudson §2.4.3 substrate — “for the beneficiary trusts create proprietary rights in the trust property AND personal rights against the trustees”. Multi-aspect captures both. Validates MQ-009 Axis-2 δ working for complex classes.

Magic Triangle SUBSTANTIVELY COMPLETE
