Three shapes survived ValidateSelfAttributedClaim because the pattern
matched only the exact configured identity:

  Echo has filed a correction.
  Echo filed a correction.
  Echo has created a tracking issue.

Each is the identity shortened, which sirens-echo#559 records as the
settled half of that issue.

The obvious fix is to derive the last word of the identity, and it is
wrong: sirens-echo#557 shipped a test against exactly that, because the
last word of "Sirens Deep of Coilyco" is the organisation. Measured
before building anything, the proposed derivation fails that test.

So the short form is declared rather than derived. Definition gains an
optional self_aliases, Echo declares "Echo", and Deep declares nothing,
so no derivation exists to go wrong on a future identity.

A blank alias is dropped, because an empty branch in the alternation
matches at every position and would refuse every reply.

The corpus scores against a copy of Echo's aliases, so a test fails if
the copy drifts from the definition.
