This paper proposes that D₀ = 0.05 emerges as a scale-invariant structural critical point across two physically distinct domains separated by 28 orders of magnitude in length scale. This is a structural alignment hypothesis, not a universal constant declaration. [STEM] At the semiconductor nanoscale (L1 domain): three methodologically distinct derivation paths converge on D₀ = 0.05. (1) Percolation theory with a = 45 nm (CPP pitch, IRDS 2024) and ξ = 122 nm yields (45/122)³ = 0.0502. (2) Samsung SF2-to-SF3 area scaling ratio = 0.05 (published). (3) Defect density boundary γ(T) in DOI_17 observes D₀ = 0.05. At the cosmological scale (L6 domain): DESI DR2 BAO data (arXiv:2503.14738, Table IV) reports α_iso = 0.9749 at z = 0.706 (LRG2), yielding Δ = |1 − α| = 0.0251 at 3.75σ. The ratio D_M / D_μ = 0.0251 / 0.05 = 0.502 ≈ 1/2 with 0.4% deviation (A3 alignment, PASS). [BRANCH] A derived correlation length ξ_eff = 5.43 Mpc is obtained by applying D = (a/ξ)³ with a = 2 Mpc (local clustering cell scale, distinct from BAO sound horizon ~150 Mpc) and D₀ = 0.05. This is explicitly a structurally derived value, not a directly measured r₀. Independent LRG survey literature (Zehavi et al. 2011; Marulli et al. 2013) reports r₀ ~ 5–8 Mpc, which is consistent but not confirmatory. Empirical verification against DESI DR2 density-field data is designated HOLD. [CROSS] The mapping Δ = |1 − α_iso| → D_M is an interpretative structural mapping, not a formally derived physical equivalence. The ×2 relation (D_M ≈ D₀/2) is an empirical alignment, not a derived projection coefficient. Five HOLD items define the remaining verification roadmap (z_eff=20 cosmic connectivity, ξ_eff vs. measured r₀, density-field F(ρ), ×2 physics mechanism, a=2 Mpc sensitivity). No claim exceeds its evidential basis. Limits Section Item Status D₀ = 0.05 at semiconductor scale CONFIRMED — 3-path convergence (LOCKED) Δ_DESI = 0.0251 at LRG2, z=0.706 CONFIRMED — DESI DR2 Table IV, 3.75σ D_M ≈ D₀/2 alignment STRUCTURAL HYPOTHESIS — physics TBD ξ_eff = 5.43 Mpc DERIVED VALUE — not measured D₀ as universal constant NOT CLAIMED z_eff = 20 cosmological meaning HOLD DESI density-field connectivity HOLD a = 2 Mpc justification HOLD — sensitivity acknowledged Truth Declaration This work is an original theoretical proposal by an independent researcher (architect, 25yr; no institutional affiliation). It contains confirmed L1 results (LOCKED), published DESI DR2 data reproduced exactly (no hallucination), structural hypothesis clearly labeled as such, derived values explicitly distinguished from measured values, and open HOLD items with defined verification paths. No universal constant is declared. Published as a structural hypothesis inviting independent verification.
