Compression and Energy-Efficient Archival of Spiral-Domain Encoded Time-Series Trajectories: Discretization, Codec Composition, and Deployment-Scale Storage Economics- Supplementary Reproducibility Archive

Supplementary reproducibility archive for Paper 4 of the spiral-domain encoder validation campaign, targeting IEEE Transactions on Storage (manuscript in preparation).Coverage. 9 pre-registered studies (Studies 54–62, Phase IX + Phase X of the spiral-domain encoder validation campaign). 27 hypotheses, 17 SUPPORTED (63%), 10 honest bounded negatives substantively interpreted.Substantive findings. 4× structural compression via discretization; 46.75× cumulative compression with delta-encoding + zstd-9; 71.72× maximum with zstd-22; 33.02× for 90%-idle daily-living monitoring; linear storage scaling R² > 0.999 across four duration tiers (1 min, 1 hour, 24 hours, 1 year); 1,000-device smart-factory deployment fits 3 TB/year ≈ $830/year AWS S3 budget.Contents.• README.md — submission-package map and reproduction instructions• preregistrations/ — frozen pre-registration .md documents with literal-threshold decision rules• reports/ — per-study .md verdict reports against frozen rules + phase summaries• runners/ — deterministic Python runners (PYTHONHASHSEED=0) reproducing every reported measurement• raw_data/ — per-study CSV outputs and machine-readable JSON verdict blocks• figures/ — manuscript figures (PNG, 300 DPI) + figure-build Python script• code/ — encoder source code (spiral.py), supporting modules (baselines.py, data.py), and package __init__ filesReproducibility. Full validation pipeline is reproducible end-to-end under PYTHONHASHSEED=0 on a standard Python 3.9+ installation with NumPy 2.0+, SciPy, and the python-zstandard binding. Reference machine: Apple Silicon arm64 (M-series), macOS 14. See README.md for per-study run commands.Methodological discipline. Every hypothesis was pre-registered with externally anchored decision rules frozen prior to runner execution. Zero post-hoc threshold adjustments were applied. Honest bounded negatives are interpreted substantively rather than discarded.Related companion archives.
