Design Blueprint: Sizing a Water Retting Tank for Flax

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24119315): Water retting is the step that decides whether flax straw becomes spinnable fibre or compost, and it is usually sized by whatever tank a household happens to own. 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.
