C-D21-SEED-BLOCKED

Seed MATERIALIZATION BLOCKED-COMPUTE (measured): the two built routes that materialize the seed set both exceed the frozen caps. Distinct 13-multiset signatures grow 6 (p=23) -> 15511 (p=29); the Cartesian small-prime seed set is the CRT product to pass the threshold, at least 2^519; the meet-in-the-middle half-space is 1e9..1e17 at inventory primes. SCOPE (Contractor): this blocks the two explicit materialization methods, NOT every implicit approach. The product of local signature sets is not the mandatory state space, cross-prime constraints may eliminate most states before they are generated. Not a compatibility claim, not a counterexample

In plain language

The two ways we tried to list every starting fingerprint are astronomically large, so those routes are cost-blocked. That does not mean every method is blocked, keeping the object symbolic may prune most states before they exist.
