The first primes with explicit constructive bounds

k>0 ⇒ ∃ first k primes p₁<⋯<pₖ with pₖ<2^(2^k)

Construct the actual first k primes, prove that none is omitted, and bound the last prime by explicitly constructed powers of two.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

Exact mathematical boundary: Every successor is the globally least prime above its predecessor. This is not a sparse Bertrand chain. The bound theorem constructs the list and both power witnesses from k≠0 alone; the separate total-list theorem includes k=0.
