Western sidereal
Western practice that measures the zodiac against the fixed stars rather than the equinox. Registered here to make the frame disagreement explicit: a sidereal rule and a tropical rule that use the same sign name do not refer to the same region of sky.

Epistemic status
Every rule below is recorded as documented interpretive tradition with no empirical validation. The provenance badge states how faithfully the record represents its source; it is not a measure of whether the rule is true. Prohibited uses: medical diagnosis, prognosis, or treatment decisions; legal conclusions or advice; investment, trading, or other financial decisions; predictions of death, disaster, or pregnancy outcomes; claims that a chart determines personality, capability, or behaviour; guarantees about future events; high-stakes decisions taken on astrological grounds alone; employment, lending, insurance, or housing decisions about a person.
