# Named rule set. Each rule targets GGUF tensor names by regex (llama-quantize
# --tensor-type semantics: std::regex_search, FIRST match wins).
# Order here IS the match order -- most specific first.
rules:
  # --- norms: never quantized by llama.cpp (name contains "_norm.weight"),
  #     kept at source dtype. Listed for documentation/verification only.
  norms: f32

  # --- router: llama.cpp never quantizes ffn_gate_inp; exp_probs_b is 1-D.
  #     Both stay at source dtype. Documented, enforced by the verifier.

  # 2.5 GiB *under* the 82-90 GiB target. Q3_K spends that headroom on exactly
  # the tensor the stated principle singles out: 85.48 GiB, in target.
  # Preferred over widening the edge-layer set, which would instead change a
  # parameter the work order fixes explicitly.

# v1 pilot variant: IQ2_XXS requires an importance matrix in llama.cpp

  # Pilot: substitutes Q2_K for IQ2_XXS so the end-to-end pipeline completes
  # without blocking on imatrix generation. Q2_K down is kept (rather than Q3_K)
  # to stay inside the size target: 87.77 GiB. This is a usable artifact, not a
  # throwaway -- it is the Phase C/D baseline while the imatrix is produced.
