## Verification Command

Run this to audit current status:

```bash
# Count exported functions per binding
echo "=== Python exports (periodic_linear + kinetics) ===" && \
grep -E "def (compute_periodic_dos|solve_periodic_randnla|bloch_phase|build_bloch_hamiltonian|assemble_periodic_operators|bz_integrate_scalar|bz_integrate_vector|validate_electron_count|validate_kmesh_weights|extract_kinetics_diagnostics|solve_microkinetic_network|solve_microkinetic_steady_state|analyze_gsm)" crates/python/src/experimental.rs | wc -l && \

echo "=== WASM exports (periodic_linear + kinetics) ===" && \
grep -E "pub fn (compute_periodic_dos_wasm|solve_periodic_randnla_wasm|bloch_phase_wasm|build_bloch_hamiltonian_wasm|assemble_periodic_operators_wasm|bz_integrate_scalar_wasm|bz_integrate_vector_wasm|validate_electron_count_wasm|validate_kmesh_weights_wasm|extract_kinetics_diagnostics_wasm|solve_microkinetic_network_wasm|solve_microkinetic_steady_state_wasm|analyze_gsm_mbh_htst_step_wasm)" crates/wasm/src/experimental.rs | wc -l && \

echo "=== CLI exports (periodic_linear + kinetics) ===" && \
grep -E "pub fn cmd_(compute_periodic_dos|solve_periodic_randnla|bloch_phase|build_bloch_hamiltonian|validate_electron_count|extract_kinetics_diagnostics|solve_microkinetic_network|solve_microkinetic_steady_state|analyze_gsm)" crates/cli/src/experimental_cmds.rs | wc -l
```

Expected output (Session 6):
```
=== Python exports (periodic_linear + kinetics) ===
13

=== WASM exports (periodic_linear + kinetics) ===
13

=== CLI exports (periodic_linear + kinetics) ===
9
```

Total new functions: **13** (9 periodic_linear + 4 kinetics)
All platforms compile + all 676 tests pass ✅
