VerificationTest
Evaluates input and compares it with expected, returning a TestResultObject.

Details
- Held: input does not evaluate until the constraints (TimeConstraint, MemoryConstraint) are in place around it.
- Outcome is one of "Success", "Failure", "Error" (input raised, or a constraint was requested this process cannot honor) or "Aborted" (TimeConstraint fired).
- MemoryConstraint in-process reports Error rather than silently skipping the check — real enforcement needs the isolated evaluator, where it comes from the worker's own resourceLimits.
- TestResultObject's operands are rules — Outcome, Input, ExpectedOutput, ActualOutput, AbsoluteTimeUsed (seconds, rounded to the millisecond), and TestID when given — the same rule spelling @enumeratio/engine's optionsOf/ruleOf read elsewhere in this codebase.
Examples
Basic #
input matches expected
live ↗input evaluates but does not match expected
live ↗one argument: a predicate that evaluates to True
live ↗Scope #
a symbolic computation checked against its expected form
live ↗a TestID is carried into the result
live ↗a SameTest with a tolerance: passes
live ↗Possible issues #
MemoryConstraint in-process is an Error, not a silently-ignored option
live ↗one argument succeeds whenever input evaluates without an error
live ↗the default comparison is structural: mathematically equal but differently written is a Failure
