Equivalence Reasoning

The agent patch does not implement the core intended refactor scope (removing redundant assertions across validation helpers and schema-parsing paths in `v3`/`v4` core utilities). It instead changes `v4/classic/parse.ts` and heavily rewrites `v4/core/errors.ts`, leaving most targeted helper/schema assertion sites untouched. This is not an equivalent implementation of the described change.
Code Review
The agent patch is unlikely to satisfy the intended task: it largely edits different files/concerns than requested, introduces broader typing rewrites, and still uses forced casts at key return points.
The task targets validation helpers and schema parsing assertion cleanup (including contextual error-map handling), but this patch only edits v4 classic parse wrappers and v4 core error-formatting internals. That makes the intended refactor likely incomplete/unmet.
Despite introducing multiple helper types, both `formatError` and `treeifyError` still end with explicit casts to target return types, which undercuts the stated goal of relying on inferred types instead of forced assertions.
The overloads for `formatError`/`treeifyError` were changed from optional mapper generic signatures to required mapper in the generic overload, while implementation remains optional. This broad API typing change is risky and not necessary for the stated assertion cleanup.
