Court Mesha D1-or-D9 predicate foundation ​

personal.court-mesha-d1-d9-foundation

A three-valued, source-scoped Court predicate accepts authoritative Mesha D1 immediately or guarded Mesha Lagna Navamsa when the exact sidecar Lagna agrees with the local Drik frame.

Computation method ​

Method type: algorithm

Evaluate the source's D1-or-D9 Boolean only after preserving local Lagna authority and the selected guarded BPHS Navamsa convention, then aggregate every represented state with reject-first precedence.

Process ​

  1. Reject unsupported systems and missing, conflicting, or transition-guarded local Lagna authority to unknown.
  2. If the authoritative local D1 Lagna is Mesha, pass without requiring sidecar D9 facts.
  3. Otherwise require a valid exact sidecar Lagna whose Rasi equals the authoritative local D1; disagreement or absence is unknown.
  4. Derive D9 with the selected modality-based Navamsa sequence and return unknown inside 0.01 degrees of each 3 degrees 20 minutes division boundary.
  5. Pass when D9 is Mesha and fail when both resolved D1 and D9 are non-Mesha.
  6. Across a window, any resolved failure controls; otherwise unknown controls; an all-pass result still becomes unknown when D1 or D9 transitions are incomplete or the chart-request budget is exhausted.

Formulae ​

Court Mesha D1 or D9 ​

text
pass = (D1 = Mesha) OR (D9(local-agreed exact Lagna) = Mesha)
  • D1: authoritative local Drik/Lahiri Lagna Rasi
  • D9: guarded BPHS-modality Lagna Navamsa
  • guard: plus or minus 0.01 degrees at every 3 degrees 20 minutes Navamsa division boundary

Worked example ​

Vrishabha D1 with Mesha D9 ​

Inputs

  • Authoritative local D1: Vrishabha
  • Sidecar Lagna: Vrishabha 11.00 degrees
  • No boundary or authority conflict

Calculation

  1. The local and sidecar Rasis agree, so the exact degree may be used for D9.
  2. Vrishabha is fixed, so Navamsa starts from its ninth sign Makara; 11.00 degrees is the fourth division, which advances to Mesha.
  3. D1 is not Mesha but D9 is Mesha.

Result

  • Status: pass
  • The reject predicate does not fire

Method notes ​

  • The shared JSON oracle is synthetic contract evidence, not a source golden or external ephemeris validation.
  • The specified-unwired conditional-admission record allows only a valid non-Mesha D1 candidate with an unresolved D9 alternative to be provisionally retained when issue 285 is implemented; a resolved D1/D9 miss must not survive.

Contract ​

Owning layer: personal
Claim kind: textual-rule
Time basis: Each exact chart sample in the candidate's half-open civil-minute window; D1 and Lagna-Navamsa transitions must both be completely represented before an all-pass window resolves.

Inputs ​

  • canonical local Drik/Lahiri D1 Lagna Rasi
  • sidecar Lagna Rasi and exact degree
  • Lagna authority/transition state
  • window transition coverage
  • chart-request budget state

Outputs ​

  • per-state pass, fail, or unknown with evidence
  • whole-window pass, fail, or unknown
  • unwired conditional-admission contract for issue 285

Raman supplies the Mesha D1-or-Navamsa clause. Local-D1 precedence, the exact-degree agreement gate, the 0.01-degree guard, reject effect, and three-valued window precedence are explicit product conventions.

Scope: Supports rejection of Tuesday and Saturday; admission of Ashwini, Rohini, Mrigashira, Pushya, Uttara Phalguni, Hasta, Chitra, Anuradha, Dhanishtha and Revati; Mesha Lagna or Mesha Navamsa; Guru in a Trikona from a strengthened Lagna; no malefic in the 6th; separation of the Lagna and 6th lords; and the non-predictive peace configuration. The Drik website post-screen now evaluates all five clauses across every sampled, Lagna-stable state: two exact rejection gates, two score-neutral preferences and one non-ranking information pattern. Unknown or boundary-adjacent facts retain the slot with visible review; mandatory failures remove it. The passage does not expand 'the usual unfavorable Tithis'; registered alternatives and the unchanged operational choice are separate claims. The profile is limited to filing or initiating a lawsuit and does not cover hearings, responses, settlement, appeals or outcome prediction. Legal obligations always take precedence. The legacy litigation API key resolves explicitly to this profile and is not a separate election.

Limitations ​

  • This issue delivers an additive Python/TypeScript predicate foundation only. It remains specified_unwired: the current D1-only base shortlist is unchanged until conditional admission issue 285 and Court integration issue 400 land.
  • Only the Drik/Lahiri path can resolve the predicate. Missing local Lagna authority, sidecar/local Rasi disagreement, malformed facts, guarded Navamsa boundaries, incomplete transitions, and request-budget exhaustion remain unknown.
  • The formula uses Lagna Navamsa only; it does not implement a general election baseline, strength, fortification, Shadvarga, or outcome prediction.
