Create, extend, debug, and validate Quasar LLK performance tests and their PerfRunType kernel paths. Use when adding perf_[op]_quasar.py, wiring PerfConfig, implementing UNPACK_ISOLATE / MATH_ISOLATE / PACK_ISOLATE / L1_CONGESTION, or investigating implausible Quasar perf metrics and dvalid handshakes.

Route gh-aw workflow design/create/debug/upgrade requests to the right prompts.
Convert LLK lib/API tile-size args to ckernel::TensorShape and maintain TRISC TensorShape coverage. Use when adding TensorShape parameters, replacing face_r_dim/num_faces, editing LLK_VALIDATE_TENSOR_SHAPE_*, regenerating tensor_shape_coverage_*.h, or reviewing TensorShape PRs.
Audit LLK code for races on the backend CONFIG register file where differently-named fields share the SAME 32-bit config word — both cross-thread (unpack/math/pack write the same word) and intra-thread (a full-word write clobbers a sibling field the same thread set elsewhere). Use after adding/changing any ALU_FORMAT_SPEC / ALU_ACC_CTRL / ALU_ROUNDING_MODE / STACC_RELU / THCON_SEC* write, any WRCFG_32b/cfg[]= full-word write to a multi-field word, or any cfg_reg_rmw_tensix on a word another thread also touches.
Audit hand-written Tensix/SFPU instruction sequences for missing pipeline-latency padding — where a dependent instruction consumes a multi-cycle-latency result before it is ready and a NOP (or independent-instruction spacing) is required. Use after touching any raw TTI_SFP*/TTI_* sequence, ckernel_sfpu_* kernels, or hand-assembled instruction streams. NOT a cross-thread race — an intra-thread micro-architectural hazard.
