+# Ashtakavarga Deep Support Weighting v1
+
+Date: 2026-06-28
+
+## Scope
+
+This pass upgrades the newly bridged finance evidence layers from visibility-only into controlled low-weight score modifiers:
+
+- `PAV / Prastara AV`
+- `Sodhita AV`
+- `Kakshya`
+
+## Weighting
+
+The v1 weights are intentionally small:
+
+- `PAV supportive`: `+2`
+- `Kakshya supportive`: `+2`
+- `Sodhita obstructive`: `-2`
+- `Kakshya obstructive`: `-2`
+
+## Boundary
+
+These weights are not allowed to directly mint or revoke:
+
+- `dominant_label`
+- `payout_label`
+
+They only adjust the route score through the existing threshold system.
+
+## Why This Matters
+
+The project already computed these layers, but they were previously dead weight inside strict adjudication.
+
+This pass keeps the scoring conservative while letting deeper Ashtakavarga and degree-trigger signals actually influence finance ranking.
+
+## Still Open
+
+- calibrating whether `PAV` should distinguish contributor identity more sharply
+- deciding whether `Sodhita` should also have a positive support path
+- tying `Kakshya` more directly to transit timing instead of route-average usage
+- validating the weights against external oracle cases before claiming mature timing precision
