encodeModSystemAddress(parts, origin): bigint

Defined in: src/astro/system-address.ts:400

Encode system-name parts and a resolved region origin into a modulated address.

SystemNameParts

The parsed system-name parts, as parseSystemName returns.

NamingRegionOrigin

The region origin (internal units), from resolveNamingRegionOrigin.

bigint

The 64-bit modulated system address. These routinely exceed 2^53, so keep them as bigint (or a decimal string) rather than a JS number.

Prefer encodeSystemAddress for the normal id64; use the modulated form only when a tool you are feeding expects that specific layout.

If the mass code is outside 0–7, a letter is outside 0–25, n1 is not one the boxel packer accepts, the origin has a negative coordinate, the name's boxel code or sector falls outside the address layout, or the sequence does not fit the 15-bit modulated field.
