As of 1 October 2026, how many distinct issuers hold an issuer rating?

Tests: Everything at once: identity, withdrawal, instrument versus issuer, ceiling versus rating.

Expected: count = 12

❌ R1 csv run 1 graded by code

13. Counting distinct legal entities with an LTIDR/STIDR-type rating on 1 Oct 2026 gives E01, E02, E05, E06, E08, E09, E10, E12, E13, E14, E15, E16 and CV. E03 and E17 are duplicates of E02 and E10, and E07 was withdrawn (A19).
