root 1b4828f293 MELI Fraud: case-specific scaffolding scripts (3 chassis variants) ...

Three one-shot Python scripts that build the MELI Fraud As-Is /
To-Be .drawio pair by cloning an Oracle Architecture Center chassis
and overlaying MELI-specific labels, region renames, and workload
pills. Useful as worked examples of the chassis-then-overlay
transform pattern (drawio_template_transform.DrawioTemplate) that
the diagram procedure recommends:

  • build_meli_fraud_from_adbsplusadbd.py — clones the locally
    accepted ATP-S/ATP-D side-by-side reference and partitions cells
    into AS-IS / TO-BE panels by x-coordinate.
  • build_meli_fraud_from_crossregion.py — uses Oracle's
    exadata-dedicated-cross-region-dataguard ref-arch (two regions
    with DRG + RPC + Data Guard already drawn) as chassis and only
    overlays MELI-specific pills.
  • build_meli_fraud_from_templates.py — combines the in-region and
    cross-region Exadata ref-archs and clones the in-region
    topology to the right for the Montreal DR.

All three honour the standing rule: do not edit text inside Oracle
SVG stencil shapes — overlay new mxCells in whitespace instead.
