 the target calculus is intentionally lower level than the source and trades abstraction for control over layout and calling. it has decent tuple and sum representations and uses explicit box and unbox operations to mediate between them. equality on integers and booleans is primitive rather than encoded as well as recursive binding being built in rather than derived

+the audit path now records pass-boundary observations for source, specialisation, inlining, effect rewriting, and representation lowering. each corpus case is checked against relation preservation, target arity/shape validation, termination class preservation, and effect trace preservation. unsafe profiles intentionally refute these invariants so optimiser bugs show up as small source/target deltas rather than vague failures.

+the source calculus also has an explicit `tick` effect. this is enough to expose unsound dce-style rewrites: eliminating a dead binding is only valid when the eliminated term is effect free.
