**Claim (as registered):** A third routing-instrument failure mode -- the language field is blank/unusable but the script field alone was enough to identify the tradition -- never accounts for 2% or more of a complete state's records.

**Proposed mechanism:** Proposed to reflect one specific state's institutional cataloguing pattern (Tibetan-script rows there most often carry a usable script token even when the language cell does not parse cleanly), making that state the natural training-side maximum for this specific pathway.

**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:** Maximum 1.60% (the Tibetan-presence state); every other complete state under 0.84%.

**Holdout test and outcome:** Tested across all nine India holdout states/UTs; every state's share stayed under the 2% ceiling.

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