2026-09-25: One compiled kernel target: its KernelTarget identity, kernel blobs and MODEL.toml declarations.

Each blob is one compiled module, emitted as &'static [u8] by build.rs (include_bytes!): PTX text for NVIDIA, binary objects for SCALE, HIP and Metal.

Fields

target: KernelTarget

ptx_arch: &'static str

2026-09-25: The kernels/<hw>/HARDWARE.toml [hardware].arch this target was compiled with, verbatim (sm_90a, sm_121f, gfx1151). KernelTarget::arch holds the same string with an a/f suffix stripped (build_arch::kernel_target_arch). The GPU arch preflight judges compatibility on this field, because the suffix changes which devices the PTX runs on; it skips an empty value.

modules: Vec<(&'static str, &'static [u8])>

sampling: SamplingPresets

behavior: ModelBehavior

model_type_matches: Vec<ModelTypeMatch>

match_names: &'static [&'static str]

2026-09-25: MODEL.toml [model] match_names: case-insensitive substrings of a checkpoint reference (HF id, --model-name, resolved model dir) that identify checkpoints this target serves. Consulted only to break a tie between targets that declare the same (model_type, hidden_size); see crate::resolve::resolve_target. build.rs (validate_collision_match_names) panics if a colliding target leaves it empty.

dflash: Option<DflashConfig>

2026-09-25: DFlash drafter pairing; None when MODEL.toml has no [dflash] section with a draft_model.

shadowed_dropped: &'static [(&'static str, &'static str)]

2026-09-25: (module, kernel) pairs this target’s leaf-role files drop relative to their common/ namesakes: the common/ file defines the kernel, the model’s file of the same name does not, and a model file replaces its namesake whole. The boot kernel audit reports them per module.

expected_absent: &'static [(&'static str, &'static str)]

2026-09-25: (module, kernel) lookups this model’s dispatch may issue and fail to resolve without that being an error, from MODEL.toml [expected_absent]; the build panics on an entry without a reason. The boot kernel gate refuses to serve on any other unresolved lookup unless --dangerously-allow-unresolved-kernel-lookups is set.
