Module lattice 

Interpreter cone lattice report — what extraction actually did (engines.md §2).

Walks a compiled program and reports its engine mix: which cones formed (members, boundary shape), which nodes stayed on the interpreter, and the lattice headroom per node — P3 classifiability and whether the node has a compiled P2 form (a compiled_u64 op or a slot kit). The headroom column counts the candidates for running P2 closures at cone boundaries: nodes that are P2-capable but not JIT-classifiable run P1 dyn dispatch on the interpreter.

Used by the cone-formation tests (tests/core_with_library.rs).

Structs

ConeEntry

One fused cone in the compiled program.

LatticeReport

Engine-mix report for one compiled program.

ResidueEntry

One node left on the interpreter.

Functions

lattice_report

Walk program and report its engine mix.
