Trap

Atlanta-rooted, 808-driven. Triplet flows, hi-hat ride, repeated ad-libs as hook reinforcement. Code-switch fluency across registers.

Parent arc · SA#19

A genre we cannot evaluate cannot be a genre we can serve.

Rap is the proof-of-concept arc. 20 builds. Phonology layer, audit primitives, 4 subgenre profiles (Boom Bap, Trap, Drill, Conscious Rap), Haiku critic loop, per-bar validator, 30-hit corpus calibration, public Forbidden Archive of 10 rap-specific failure modes. Every subsequent genre arc inherits this pattern.

The load-bearing primitive is Phonology + Per-Bar Validator — applied to every rap lyric the forge produces, including Trap.

Forbidden Archive · 10 failure modes

Trap inherits the full Rap Forbidden Archive. The critic loop flags any of these by canonical name.
