Dignity, rulership, and house-lord disagreements
How changed sign labels and tradition-specific rulership schemes propagate into dignity, dispositors, house lords, and eligible interpretation rules.
Frame comparison · released 2026-08-18
Shared fact substrate
The celestial bodies and their geometric directions are unchanged; dignity and rulership are symbolic classifications supplied by a named tradition.
Required shared inputs
- Frame-specific sign placements
- Frame-specific ascendant
- Named rulership table
- Dignity doctrine
- Tradition-scoped rule pack
Tropical view
A tropical tradition applies its sign labels, rulership scheme, dignity conditions, and house system without borrowing Jyotiṣa lordship logic by default.
Lahiri-sidereal view
A Jyotiṣa model applies Lahiri rāśis, whole-sign houses, graha rulership, and source-bound lordship rules inside the sidereal namespace.
Where they agree
The two models may assign the same ruler or dignity in some charts, but accidental agreement does not merge the underlying rule systems.
Where they disagree
A planet can change sign, dignity, dispositor, house lordship, and interpretive eligibility. The disagreement is preserved at every derived step rather than only at the final paragraph.
Preservation policy
Emit a derivation chain from frame-specific sign to ruler table to dignity or lordship to rule ID, with tradition and source attached to every rule.
Prohibited synthesis
Do not choose the stronger dignity, combine two rulers into an unlabeled result, or treat agreement as independent empirical confirmation.
What empirical comparison requires
Treat tropical and sidereal outputs as separate candidate models. Any performance claim requires preregistered features, outcomes, horizons, baselines, model-selection policy, multiplicity control, and prospective scoring that retains misses and abstentions.
Method sources
These sources define calculation and namespace policy. They do not determine which astrology system is true.

Named, versioned rule namespaces and the separation between source provenance and empirical support.
Boundary: A well-sourced traditional rule remains an unvalidated interpretive claim unless separately tested.
- Tropical versus sidereal astrology
Maha Celestial
The policy that tropical and sidereal charts remain parallel declared models with separate feature and rule namespaces.
Boundary: The guide is a methodology declaration, not an adjudication between traditions.
