// dispatch_mra.go wires MRAScore into the dispatch table at slot
// AlgoMRA (26 — see algoid.go).
//
// NOTE: MRACode and MRACompare are public but NOT dispatched. The dispatch
// table maps AlgoID to (a, b string) float64; MRACompare returns (bool, int)
// (the catalogue's only non-float64 return shape per CONTEXT.md §6 LOCKED).
// Consumers wanting the raw 0-6 NBS similarity counter call MRACompare directly.
// Consumers wanting binary 0.0/1.0 (e.g. Scorer, MongeElkan inner) call the
// dispatched MRAScore.

// init registers the MRA dispatch entry at AlgoMRA (26). Q14b option A
// (Phase 8.5 Plan 15a) — explicit init replaces the var _ = func() bool
// {...}() pattern per the determinism-standards SKILL (pure-write into a
// pre-allocated slot; no IO, no time, no goroutines, no ordering
// dependency on other init functions). This runs before any test or
// caller can invoke the dispatch table, ensuring that MongeElkanScore /
// MongeElkanScoreAsymmetric and Scorer dispatch paths see the registered
// function.

	dispatch[AlgoMRA] = MRAScore
