Simha-stha Guru and Shukra

panchangam.simha-stha

Jupiter or Venus in Simha is flagged for activity-specific restrictions.

Assurance

Level	Current statement
Documented and traceable	Yes — the canonical record includes the process and a worked example.
Regression or reproduction checked	Linked to 1 repository test file(s).
Independently source-supported	Not recorded as independently verified. The disclosed provenance state remains authoritative.

Computation method

Method type: decision-table

Return true exactly when the already-computed Guru or Shukra Rashi name is Simha.

Process

1. Receive the planetary Rashi name or null from the upstream longitude-to-Rashi computation.
2. Compare it for exact equality with Simha.
3. Return the Boolean result without applying strength, dignity, aspect, or time-window logic.

Worked example

Exact-name classification

Inputs

• Guru Rashi: Simha
• Shukra Rashi: Karka

Calculation

1. Simha equals Simha, so Guru passes.
2. Karka does not equal Simha, so Shukra fails.

Result

• simha_stha_guru=true
• simha_stha_shukra=false

Method notes

• The function classifies an upstream sign result; it does not calculate planetary longitude.
• Surya Siddhanta and Vakya leave these flags at model defaults.

Flag behavior is tested; exact scope and source locator remain open.

Evidence class: textual
Verification state: needs_locator
Locator: No precise locator is registered.

Scope: Special Yogas, Panchaka labels, Khara month, Pitru Paksha, Simha-Stha, Maudhya, Anandadi Yoga, Disha Shoola, Nakshatra Mukha and Panchaka Rahita are separate traditional classifications. The group exists to expose evidence debt and grants no umbrella textual authority; each component needs its own inspected rule table and regional boundary.
