**Rule:** Omit production date from filenames. Include it only when multiple production runs for the same temporal period coexist in the same distribution channel. When present: `{YYYYMMDD}` as the last token before the extension.

P2 Badge Document the omitted temporal field

For new EU Hydro deliveries, this is now labeled a compliant full filename even though it omits the temporal field required by the canonical template and token-count invariant in Principle 5, while Principle 8 defines no timeless/optional temporal case. Because dropping _S2026_ is intentional, add an explicit atemporal exception and reflect it in the filename tree/schema; otherwise implementers following this document cannot determine whether EUROPE is an extent or a shifted temporal token.

P2 Badge Remove the remaining EU Hydro product-code branch

Removing this variable branch does not fully drop EU Hydro from the filename tree: the By Product Code section at lines 49–50 still advertises EUHYDRO-NET_S{YYYY}_R10m_EUROPE_3035_V02-R00.gpkg. Readers therefore still see the obsolete pattern that this commit replaces with NET-LINE; remove or update that earlier branch as well.
