Morinus Primary Directions Truth Card

Historical Name

• Morinus

Mathematical Basis

• circle-of-position primary-direction family
• on the current admitted conjunction-style surface, it uses Morin's under-the-pole treatment, presently the same runtime law as Regiomontanus
• direct is the primum-mobile arc carrying the promissor to the significator's circle of position; traditional converse exchanges those roles rather than merely negating a generally asymmetric arc
• on the explicit Morinian aspect branch, Moira now admits the circle-of-aspects projection when the service layer supplies:
  • delta_max for the source body's current node-to-node path segment
  • the motion coefficient k indicating approach to or departure from maximum latitude
  • explicit handed aspect angle
• the admitted Morinian aspect equations are:
  • lambda' = asin(sin(delta_P) / sin(delta_max)) + k * aspect
  • AE = asin(tan(delta_P) / tan(delta_max))
  • AG = atan(cos(delta_max) * tan(lambda'))
  • delta = asin(sin(lambda') * sin(delta_max))
  • lambda = lambda_P + k * (AG - AE)

Interpretive Meaning

• perfection through a Morinian circle-of-position doctrine
• the full Morinian distinctness is expected to sharpen when the aspect doctrine is widened beyond the current conjunction-style branch

Current Moira Admission

• admitted as a narrow explicit branch
• runtime-selectable on:
  • in_mundo
  • in_zodiaco
• active relation policy on the explicit aspect branch:
  • conjunction
  • opposition
  • zodiacal_aspect
• explicit Morinian aspect-plane projection is admitted for zodiacal aspect-point promissors when MorinusAspectContext is supplied by the service layer

Boundary

• this does not claim that the full Morinian aspect family has been implemented
• the current branch is still only partially method-distinct:
  • conjunction-style work remains shared with the Regiomontanus under-the-pole branch
  • the aspect-plane branch is now explicit and source-backed
• on current evidence, Moira does not treat conjunction-style Morinus as a missing distinct formula awaiting discovery; it treats the absence of a source-safe distinct conjunction law as the present doctrinal limit

Epistemic Status

• historically anchored narrow admission
• the Morin Book 22 Hemminga Mars-to-Jupiter example is checked at a declared 0.06 degree tolerance because the printed source inputs are rounded; the current residual is about 0.11 arcminute

Mathematical Sovereignty

• shared_narrow
• currently shares its admitted runtime law with:
  • regiomontanus

Resolution of the Remaining Gap

• the explicit Morinian distinctness now lives in the aspect-plane branch
• conjunction-style Morinus is not currently promoted to a separate runtime law because no source-safe distinct governing formula has yet been verified
• unless such a formula is recovered, the honest long-term stance is:
  • Morinus aspects: distinct
  • Morinus conjunctions: shared with the Regiomontanus under-the-pole branch
