**Claim (as registered):** Routing abstention (records that could not be assigned to any tradition at all) never exceeds 45% of records in any complete state.

**Proposed mechanism:** A ceiling on how much of a state's data can resist tradition-routing at all, given the routing instrument's current classification logic. Training already spans a very wide range, so the ceiling was set well above the observed maximum rather than tightly.

**Scope:** Source: NAMAMI (India), a state-facetted manuscript-holdings portal (holdings, not origin -- every record is held-by, not produced-by, the state). Training: 11 states with a complete portal walk (~4.22M records: Bihar, Himachal Pradesh, Karnataka, Kerala, Madhya Pradesh, Maharashtra, Odisha, Rajasthan, Tamil Nadu, Uttar Pradesh, West Bengal). Holdout: 9 more states/union territories walked to completion after this claim was fixed (Jammu & Kashmir, Assam, Haryana, Delhi, Manipur, Puducherry, Punjab, Uttarakhand, Jharkhand), each landed as a complete, reconciled count before testing. All data comes from one portal, so survival across states shows stability within this portal's own cataloguing practice, not independently of it.

**Training-side evidence:** Abstention shares range from 0.13% up to 41.26% (an extreme outlier, roughly 3.8x the next-highest training state at 10.86%).

**Holdout test and outcome:** Tested across all nine India holdout states/UTs; every state's abstention share stayed under the 45% ceiling.

**Status:** Survived every tested holdout state.
