"""Entry-filter gates (doc 02 §1, doc 04 Rule 6).

Gates are reusable boolean masks that *filter* entries. They are **caller-
side**: a gate is AND-ed into the signal *before* it reaches the engine —
``allow = directional_signal & ~block_condition``. The engine still just
consumes a signal array. This means you can add or remove a filter without
re-validating the engine.
