- Algol has Hipparcos page identity; embedded coordinates match VizieR-propagated J2000 and other reviewed numeric fields remain product metadata.
- Algol has named fixed-star support from TRAD-BRADY-FIXED-STARS, TRAD-DE-QUINDECIM-STELLIS; the witnesses are retained as tradition-specific variants rather than merged chart use doctrine.
- Algol has reviewed Hipparcos page identity for its display name; Caput Algol has an exact De Quindecim selected-star witness and remains docs-only.
- Algol maps to HIP 14576 in the Hipparcos Main Catalog for future page-level provenance review.
- The De Quindecim Algol page identifies Caput Algol within the selected fifteen-star corpus, associates it with Saturn and Jupiter, and frames its testimony through Ascendant, Midheaven, Moon, and malefic-contact contexts.
