Design Blueprint: Archival Box Buffer

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121566): This paper addresses a practical question in storage boxes: paper made from groundwood and many papers made before the late twentieth century carry the seeds of their own decay: acids within the sheet, and absorbed from polluted air, break the cellulose chains that give paper its strength, until pages turn yellow, then brittle, then to fragments at a touch. Using a self-contained computation from stated assumptions, the study evaluates the options across the range a small operation ordinarily meets and identifies the point at which the balance of cost, quality and material use changes. The hea Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
