vyre-self-substrate

The recursion-thesis layer of vyre: using vyre's own LEGO-substrate primitives (vyre-primitives) on vyre's own scheduler / dataflow / cost- model problems.

Audit cleanup A10 (2026-04-30) extracted this from vyre-driver/src/self_substrate/ into a dedicated crate so the substrate-self-uses live at a layer that depends only on vyre-foundation + vyre-primitives — eliminating the layering muddle where backend-specific dispatch code and substrate self-uses shared one home in vyre-driver.

What lives here

55 modules implementing vyre-self-uses of substrate primitives, including:

• Megakernel scheduler (matroid_megakernel_scheduler, spectral_schedule, level_wave_pass, tensor_train_chain_fusion).
• Dataflow analyses (dataflow_fixpoint, reaching_definitions, live_variables, dominator_frontier).
• Cost models (cost_model, differentiable_autotune).
• Categorical checks (categorical_check, functorial_pass_composition).
• Topological signatures (persistent_homology_loop_signature).
• Bitset summaries, alias registry, do-calculus impact analysis, etc.
