registry.Q.all_of(tags=["actor"]).none_of(tags=["actor"]) raises an internal AssertionError while constructing the query. This makes dynamically composed filters fail when a required condition is also excluded, instead of producing an empty result.

Remove the disjointness assertion. The existing intersection/difference compiler already evaluates these conjunctions correctly, including normal cache invalidation.

Validation:

• All six component, tag and relation regression cases fail before the fix, in either builder order.
• Full suite on Python 3.10 and 3.12: 112 passed, 2 non-strict xpasses. Configured Mypy and Ruff pass.
• A game-state workload compares 720 filter evaluations with independent SQLite/set predicates, continues through 120 turns and save/load, and preserves all 12 final world states. All 720 formerly failing constructions now return the expected empty result.

This is independent of #65's cache ownership change.

OpenAI Codex assisted with investigation, implementation and validation.

It is a contradictory state. It makes sense to remove the assertion error, but I wonder if at least a warning should be raised. Or is this state so obvious that it warrants no runtime warnings at all?

[antonsoo]

Overlap can be an expected empty result when independent filters are combined, for example a required actor filter plus a user-selected exclusion of actor. A warning would flag that valid use too. This patch returns no matches quietly, matching the existing intersection/difference semantics.

I think you're right. It was a mistake for me to give this case special attention.
