研究方向

Start at the refinement-error diagnostic and trace the final expected predicate used for verification through alias and state expansion and simplification. Add tests covering multiple assignments, repeated variables, aliases, and values that cannot be represented safely. Done means the original refinement and assignments remain, while the final predicate shows substituted values without reducing the informative expression.

描述

A refinement error currently shows the original expected refinement and counterexample assignments separately. Include a readable version of the final expected predicate used for verification, after alias and state expansion and any applicable simplification, with every available counterexample value substituted.

For example:

Original expected: Positive(buffered)
Final expected:    buffered > 0
Counterexample:    buffered == 0
With witness:      0 > 0  ✗

Substitute using expression variable identities, without hardcoded alias names or text replacement. Keep the informative expression (0 > 0) rather than reducing it to false. Preserve the original expected refinement and assignments; leave values unchanged when they cannot be represented safely. Cover multiple assignments, repeated variables, and aliases in tests.

Related to #295, which covers navigating alias expansion in the diagnostic history.
