get_kernel
Get SPARKS kernel
SPARKS completeness tier for a brand in a market:
100 = resolvable (a real pack/size record is held) . 8 = registered (brand known,
pack/size pending) . 'floor' = STANDARD default (no brand-specific record).
Returns the stored tier flag — do NOT compute a score. Never returns a pack/size.

resolve_sparks
Resolve SPARKS
Two-branch SPARKS resolver (zero-pads GTIN to 14).

kernel_available}; the pack/size VALUE is NEVER returned. Route to Navigator.
Brand match is fail-closed (normalized exact match); uncertainty -> recognized:false.
