VedAstro Parity Matrix

• Generated: 2026-06-28T08:31:52.958980+00:00
• Rows: 13
• P0 rows: 11
• Local registry technique count: 89

Honesty Boundary

VedAstro calls are external adapter evidence until a capability is promoted by local tests, oracle artifacts, or strict workflow integration. This matrix does not claim clone-level parity.

Summary

• Local status counts: {"covered": 4, "missing": 1, "partial": 8}
• Recommended path counts: {"external_evidence_only": 1, "hybrid_local_plus_vedastro": 7, "local_native": 4, "new_local_impl": 1}

Matrix

VedAstro capability	Category	Local status	Path	Priority	Adjudicator use	Local assets	Gap notes
Tajika Annual	annual_prediction	partial	hybrid_local_plus_vedastro	P0	secondary	tajika.py, varshaphala.py, sahams, solar_return	Annual modules exist; yearly career/wealth/month windows need stronger strict-workflow integration.
Ayanamsa Selection	ephemeris_policy	partial	hybrid_local_plus_vedastro	P0	oracle_only	ayanamsa_utils, ephemeris_adapter_contract	Local Lahiri path is usable, but broad ayanamsa parity and public comparison artifacts remain incomplete.
Prashna / Horary	horary	covered	local_native	P0	secondary	prashna.py, kp_system.py, upagraha_gulika_maandi, sphuta_trisphuta_family	Horary modules exist but are not yet a first-class question adjudicator route.
Jaimini / Chara Dasha	jaimini	covered	local_native	P0	secondary	jaimini.py, AK, DK, UL, Chara Dasha, Jaimini marriage bridge v1	Core Jaimini exists; mission/career/marriage quality adjudicator folding is not yet exhaustive.
Report Rendering	presentation	partial	new_local_impl	P0	not_used	report_artifact API, report_builder.py, chart_renderer.py, jyotish-app export	HTML/PDF artifact path exists; polished SVG/PDF chart rendering and cloud-scale report production are not finished.
Synastry / Ashtakoot	relationship_matching	covered	local_native	P0	secondary	synastry.py, ashtakoot.py, 36-point Ashtakoot, 16-factor compatibility	Matching modules exist and API-backed; relationship adjudicator still needs a formal bridge.
MCP / API Surface	service_surface	partial	hybrid_local_plus_vedastro	P0	primary	mcp_server.py, jyotish_api_server.py, strict workflows, vedastro_service_adapter.py	Local API/MCP surfaces exist; VedAstro live adapter needs endpoint-backed smoke tests and provenance capture.
Ashtakavarga	strength	partial	hybrid_local_plus_vedastro	P0	secondary	ashtakavarga, ashtakavarga_pav, ashtakavarga_sodhita, finance_ashtakavarga_bridge	SAV/BAV is in production; PAV/Sodhita/Kakshya bridges need continued regression before being dominant labels.
Shadbala	strength	partial	hybrid_local_plus_vedastro	P0	secondary	shadbala, shadbala_advanced, shadbala_component_cap, oracle_shadbala_queue	Local component-aware cap exists; absolute external oracle closure is still incomplete.
EventsAtRange / Life Event Graph	timing_range_scan	partial	hybrid_local_plus_vedastro	P0	oracle_only	transit_trigger, dasha, narayana_dasha, vedastro_service_adapter.range_scan	Local timing modules exist, but a high-frequency day/hour event graph is not yet a local productized radar.
D1-D60 Divisional Charts	varga	covered	local_native	P0	primary	varga, varga_full, shodasavarga, divisional_charts_extended	Local varga coverage is strong; keep VedAstro/PyJHora as benchmark evidence rather than replacing local math.
Birth Time ML / Rectification Assistant	birth_time_rectification	partial	hybrid_local_plus_vedastro	P1	secondary	birth_time_rectifier.py, rectification_gate, jyotish-app rectification	Local rectification exists; ML parity with VedAstro-style service behavior is not established.
Numerology / Non-Jyotish Tools	adjacent_tools	missing	external_evidence_only	P2	not_used	-	Adjacent product feature; not required for Jyotish adjudicator depth.

Next Actions

1. Promote VedAstro adapter MVP from contract to endpoint-backed smoke tests.
2. Add a relationship bridge for Synastry / Ashtakoot before using matching scores as primary labels.
3. Build Life Event Graph v1 from local monthly/day scan plus optional VedAstro range-scan evidence.
4. Keep ayanamsa and Shadbala parity under oracle closure before claiming production tuning.
