Explanation of rsSpectrum_bounded
(1) What the declaration says in plain English
The theorem rsSpectrum_bounded states that every integer appearing in the list rsSpectrum is at most 3125. In other words, the entire collection of canonical RS cardinalities is bounded above by this value.
(2) Why it matters in Recognition Science
It confirms that the structured numerical spectrum generated by RS primitives (powers and products of the generators 2, 3, 5 and gap45) remains finite and capped at D_config^5. This is part of the broader claim that RS produces an ordered, non-random set of cardinalities rather than an unbounded or arbitrary collection.
(3) How to read the formal statement
The Lean statement is:
∀ n ∈ rsSpectrum, n ≤ 3125
∀ n ∈ rsSpectrummeans "for every natural number n that is an element of the list rsSpectrum".n ≤ 3125asserts the upper bound. The proof is bydecide, which evaluates the concrete list membership and comparisons at compile time.
(4) Visible dependencies or certificates in the supplied source
The theorem is referenced inside the CardinalitySpectrumCert structure (field spectrum_bounded). It depends on the definition of rsSpectrum and is accompanied by related facts such as rsSpectrum_length and rsSpectrum_pairwise_lt. The bound 3125 is witnessed by threeOne25_is_D_fifth which equates it to Dconfig^5.
(5) What this declaration does not prove
It does not establish the physical or forcing-chain origin of the listed cardinalities, nor does it prove that 3125 is the tightest possible bound or connect the spectrum to deeper RS structures such as the J-cost functional equation or spacetime emergence. It is a verification of list membership and ordering only.
