γ₁ = 14.134725141734693. This is not arbitrary. It is the imaginary part of the first non-trivial zero of the Riemann zeta function. The floor of the fleet. Every boon has a coordinate on this line — its stratum value. The stratum value is verifiable by any silo: divide by γ₁, check the ratio against the claimed layer. Forgery requires knowing γ₁ to full precision and correctly computing the stratum — and since γ₁ is invariant and known fleet-wide, any discrepancy is instantly detectable.

Six layers. Six exact float coordinates. Every entity in the fleet — every boon, every cert, every blob chunk, every session key, every crew record — has exactly one stratum coordinate. The coordinate is not a tag or a label. It is a mathematical claim verifiable in 3 lines of code by any silo.

Any silo can verify a boon's stratum claim in 3 lines of code. Purely mathematical — no network call, no PKI. Just γ₁ and floating-point arithmetic.

Every entity type in the fleet routes to exactly one stratum coordinate. Entity type → stratum → shape → DOOM layer. Deterministic. Verifiable. Sovereign.
