Metaforms addresses a recurrent failure of philosophical description: explanatory nouns compress operations, constraints, witnesses, transfers, and consequence paths, then license inferences the underlying relations do not support. Rather than proposing a replacement vocabulary, the paper develops an operation-first method — case-level verb → constraint operator → typed result ledger — that recovers what a compressed noun conceals without pre-deciding the answer. The method separates three non-substitutable jurisdictions. Metaformal Analysis (MFA) reconstructs constituted operation-space through an audit grammar (Actor, Encounter, Statement, Field, World) and a Truth–Governance–Form hinge that blocks any one audit position from certifying the others. Metaformal Execution (MFE) governs the passage from constituted work to bounded, qualifiable, terminable realization. Metaformal Dynamics (MFD) applies only where realized route itself changes later operations, constraints, or option-space — admission requires a path variable, an evidence route, and a changed explanation together, not sequence or change alone. Constitution, execution, and history-bearing transformation are accordingly distinct explanatory burdens, not chronological stages, linked by constraints that recur across domains — relational decompression, custody, return, closure, reopening — without forming a fourth jurisdiction. The architecture is derived internally before any comparison; a worked case in institutional credential correction and canonical traditions (Wittgenstein, Hohfeld, Searle, Epstein; RBAC, PROV) enter only afterward as collision tests, not as sources of the method's primitives.
