   Both suggestions were valid and both are fixed. Neither was pre-existing — 
the branch introduced both conditions, so they were in scope for it.
   
   **Unused scope query under lock** — confirmed. `_evidence_predicates` 
accepted `scope_entities` and never referenced it; only `_duplicate_predicates` 
and `_operational_predicates` consume it, via `_repeats_an_earlier_block`, the 
one predicate that binds a literal entity scope. The evidence category's guards 
are all correlated per-row probes, so the `DISTINCT entity_type, entity_uuid` 
lookup was dead work on the locked path — which is the path this change exists 
to keep short. `master` has no scope lookup at all, so the branch added it.
   
   Categories now declare whether their predicates take a scope, and the kwarg 
is omitted rather than passed empty, so a builder that needs a scope can't 
silently receive an absent one. The unused parameter is gone from 
`_evidence_predicates`.
   
   The re-check SQL is unchanged. Compiling each category's predicates under 
both the MySQL and PostgreSQL dialects renders byte-identical statements before 
and after, and the old `_evidence_predicates` output was already invariant to 
whatever `scope_entities` it was handed. The only behavioural delta is one 
fewer statement under the lock, for one category — strictly less work, never 
more.
   
   **Vacuous test comparison** — confirmed. `_evidence_predicates` never 
reaches `_repeats_an_earlier_block`, so patching the legacy form left 
`rewritten["evidence"]` and `legacy["evidence"]` computed by identical code and 
the assertion could not fail. The docstring's claim to cover "evidence bounds" 
overstated it.
   
   Kept the comparison rather than dropping it, but relabelled: it's a control 
that asserts the rewrite stays confined to its two categories — if `evidence` 
ever differed, the rewrite had leaked. The docstring now says it proves 
isolation, not equivalence, and no longer claims evidence-bound coverage.
   
   Unit and integration suites for this area pass unchanged (110 unit, 120 
integration, 2 skipped as engine-specific), including the seeded equivalence 
sweep.
