+# VedAstro Parity Matrix v1 Design
+
+## Goal
+
+Create a repeatable parity matrix that compares public VedAstro capability areas with this repository's local assets and recommends the safest integration path for each area.
+
+## Boundary
+
+The matrix is a planning and audit artifact. It does not claim that local behavior equals VedAstro behavior unless the local registry, tests, and external oracle status support that claim.
+
+## Inputs
+
+- `scripts/audit_capabilities.py --mode validate`
+- `scripts/vedastro_service_adapter.py` schema and supported range-scan domains
+- A curated public VedAstro capability seed list kept in the generator script
+- Existing research indexes under `docs/research/ACTIVE_FRONTS.md`
+
+## Output Contract
+
+Each row includes:
+
+- `vedastro_capability`
+- `category`
+- `local_status`
+- `local_assets`
+- `can_call_vedastro`
+- `recommended_path`
+- `priority`
+- `license_boundary`
+- `adjudicator_use`
+- `gap_notes`
+
+Allowed `recommended_path` values:
+
+- `local_native`
+- `vedastro_adapter`
+- `new_local_impl`
+- `external_evidence_only`
+- `hybrid_local_plus_vedastro`
+
+## v1 Priorities
+
+P0 rows cover: range scanning, ayanamsa parity, D1-D60/varga parity, Ashtakavarga/Shadbala oracle checks, Jaimini/Chara Dasha, Synastry/Ashtakoot, Tajika annual, Prashna, report rendering, and MCP/API parity.
+
+## Honesty Rule
+
+External VedAstro output must be marked as adapter evidence unless it is independently promoted through local tests or an oracle artifact. Local adjudicators remain the final reasoning layer.
