The engineering code is the public identity. Only broad functional and maturity boundaries are stated here. Detailed working methods and private project naming remain controlled unless separately published.
A/B/C/D retain domain ownership. E-01 through E-06 are disclosed as a small shared-kernel direction used by several domain systems rather than as a parallel catalogue of end-user products.
