Real Horoscope & Zodiac technologies

OmenHall does not call a mixture of incompatible eras 'classical astrology'. Sky is calculated first, then a reference frame is selected, and only then a specific ruleset. Modern authored Sun-sign astrology, Ptolemy, Valens, and Lilly have different authority boundaries.

HOROSCOPE_ZODIAC_TECHNOLOGY_CONSTITUTION_V1

One real sky — explicitly selected astrological technologies

Astronomical authority and reference frame are fixed first. Only then may the selected profile derive its own houses, configurations, rulerships, dignities, or modern authored metrics. Ptolemy, Valens, Lilly, and OmenHall Modern are not one universal ruleset.

Astronomical Sky

Planet set
sun-moon-mercury-venus-mars-jupiter-saturn-uranus-neptune-pluto
House doctrine

Rulership

Dignity

Authority: Calculated positions, motion, and sky geometry before any astrological interpretation.

Algorithm: Provider-backed geocentric positions; astrological signs and symbols are not part of the physical layer.

Boundary: This mode predicts nothing and assigns no psychological influence to planets.

Aspect doctrine

Rulership

Dignity
none

Authority: Equal 30° ecliptic sectors anchored to tropical 0° Aries; these are not IAU constellation boundaries.

Algorithm: Normalized ecliptic longitude / 30°; degree within sign is stored separately.

Boundary: A coordinate sign by itself is not a personality claim or forecast.

OmenHall Modern — Solar-Sign Weather V2

Aspect doctrine
OMENHALL_MODERN_ASPECT_RULESET_V1
Rulership
OMENHALL_MODERN_RULERSHIP_DISPLAY_V1
Dignity
none

Authority: OmenHall-authored modern technology for a general selected Sun-sign forecast; not a personal natal chart.

Algorithm: Real current sky → Whole Sign frame relative to the selected sign → versioned attention weights → exact period events → interpretation.

Boundary: Question theme and AI may not change planetary positions, events, sign, or calculated attention area.

OmenHall Modern — Natal + Transit V2

Rulership
OMENHALL_MODERN_RULERSHIP_DISPLAY_V1
Dignity
optional-reference-not-calculation-authority

Authority: Natal snapshot + current sky + calculated transit-to-natal events. Unknown birth time is never replaced by invented noon.

Algorithm: Birth authority → natal geometry → current provider-backed sky → personal event timeline → immutable snapshot → interpretation.

Boundary: This is OmenHall modern symbolic astrology, not a hidden reconstruction of Ptolemy, Valens, or Lilly.

Ptolemy — Tetrabiblos I Foundation

PTOLEMY_DOMICILES_I_20_V1
Dignity
PTOLEMY_EXALTATIONS_I_22_V1; PTOLEMY_TRIPLICITY_GOVERNORS_I_21; terms fail-closed pending exact table collation

Authority: Only rules directly fixed in the selected Tetrabiblos profile: sign classes, configurations, domiciles, triplicity governors, and exaltation/fall.

Algorithm: Modern outer planets, psychological archetypes, Placidus defaults, and modern degree orbs are forbidden inside this profile.

Boundary: Historical doctrine is presented as historical doctrine, not scientifically established causation.

Vettius Valens — Anthologies Research

Authority: The Anthologies corpus is registered directly; XII Places and timing techniques are not mixed with Ptolemy before separate collation.

Algorithm: Customer calculation stays disabled until source-by-source procedure freeze.

Boundary: No generic 'Hellenistic' rules from secondary summaries are auto-filled.

William Lilly — Christian Astrology 1647 Research

Authority: The original 1647 edition is registered as a primary digital witness; horary/nativity procedures require separate collation.

Algorithm: Never activated by routing the modern OmenHall ruleset under a historical label.

Boundary: Lilly is not mixed with outer planets or modern psychological astrology.

Nirayana / Sidereal — unresolved authority

fail-closed

reference-frame-boundary

Zodiac frame
UNRESOLVED_AYANAMSA

House doctrine

Authority: The word 'sidereal' is insufficient: an explicit ayanāṃśa/reference profile, version, and procedure are required.

Algorithm: Fail-closed until the reference authority is selected and frozen.

Boundary: Never relabel tropical longitude as Vedic/sidereal.

Compare technologies on the same sky

The UTC instant stays fixed. Only the permitted derivation profile changes. Research-only and unresolved profiles must reject rather than silently run the modern engine under a historical label.

This profile requires no additional user data.

The workbench exposes provenance and procedure boundaries on an expert surface. Historical astrological doctrine is not presented as established physical causation.

Source anchors

Astronomy Engine 2.1.19 · Swiss Ephemeris cross-engine fixtures · Ptolemy, Tetrabiblos Book I (Gutenberg 70850) · Vettius Valens, Anthologies, Mark Riley translation (research corpus) · William Lilly, Christian Astrology 1647, Wellcome Collection (research witness) · Rashtriya Panchang as a nirayana/sidereal reference boundary.

Valens/Lilly are not active customer calculators until direct procedure collation. Sidereal/Nirayana is not activated until an explicit ayanāṃśa/reference authority is frozen.
