/**
 * The version as it reads: `0.8.9` placed on its tag, `0.8.9-3` three
 * commits later.
 *
 * The number can be read without instructions - that's all we ask of it. A
 * letter (A, B, C… AA, AB) was shorter, but you had to know the
 * decode, and an indicator that must be decoded indicates nothing.
 *
 * 0 (or a value that is not a positive integer) returns nothing: the
 * deployment is POSED on its version, there is nothing to add behind it.
