Methodology

Jyotisya separates astronomical calculation, doctrine, and language so fluent wording cannot silently change the chart.

Calculation profile

The reference experience uses a Lahiri sidereal profile, mean nodes, whole-sign houses, a pinned historical time-zone database, and versioned astronomical artifacts. The exact profile and hashes appear in each report.

Interpretation boundary

Calculated facts may be shown without interpretive authority. Traditional interpretations are released separately and carry an explicit status. Production answers currently render the verified deterministic answer plan. Generative prose remains research-only and production-disabled until sentence-level semantic entailment, contradiction, and safety verification has a released evaluation record.

Four release states

Available and validated; available in beta; calculated, not interpreted; and planned. The public capability matrix is generated from the same registry used by product presentation.

Limits

Jyotisya does not promise events, diagnose health, determine legal or financial outcomes, or replace consent and real-world judgment.
