real voluptuous 0.16.0 implements ``Marker.__eq__`` as ``self.schema ==
other`` — a field-name comparison with no class check, so
``Optional("x") == Required("x")`` is True (verified against the library
source, not just the audit note). The mirror compared class + field, which
kept two dict entries for one field: a ``Required(field, default=...)`` after
``Optional(field)`` LOOKED like it applied the default, while real voluptuous
keeps the first (defaultless) key object and silently drops it — the exact
t33 F-A failure mode the mirror exists to catch, i.e. the harness could mask
the bug it was built to see.
``Marker.__eq__`` is now the library's comparison and the contract tests gained
both pins: field-only equality (with equal hashes) and the mixed-marker
re-declaration that used to be masked. Reverting only ``__eq__`` makes those
two fail, which is the red proof recorded for t35.
Verified: uvx --with pytest-asyncio pytest tests -q → 276 passed, 1 skipped;
uvx ruff check custom_components tests → clean.
