Reproducible on free infrastructure

The LSEQM+DL pipeline re-runs on a free Google Colab CPU - no GPU, no paid tier. For the Bali subdomain, all 36 dekads of the 2001-2025 record, notebooks 02 to 06 - correction, metrics, quality assessment, station validation and visualisation - complete in 72.1 minutes, well inside one free-tier session. The figure excludes notebook 00 (AOI definition) and notebook 01 (data download), whose cost is set by the requested domain extent and network throughput rather than by the method.

Where the 72 minutes go

Verification (notebook 03) dominates the budget: it computes the full 31-metric catalogue at every pixel and every dekad. The per-dekad CNN training (notebook 02) is second. Environment: .

Which of these outputs is worth trusting depends on the application - see 5.3 Application classes.
