Spec for the compounding-bug-grammar insight from J's feedback on the
queryd/delta.rs unit-mismatch fix (86901f8). Adds three proposed fields
to PathwayTrace (semantic_flags, type_hints_used, bug_fingerprints),
9 initial SemanticFlag variants, and the truth::evaluate review-time
task_class pattern that reuses existing primitives instead of building
a type-inference engine. Implementation pending approval on the flag
set and fingerprint shape.
