Stop Reason

The first PDF that was not already represented by an exact raw_path: string is:

raw/Papers Cube Manual Fetch/Heavy Metals in Infant Clothing: Assessing Dermal Exposure Risks and Pathways for Sustainable Textile Policies.pdf

Identity checks show this is already represented by wiki/sources/xiong2025-heavy-metals-infant-clothing.md:

DOI: 10.3390/toxics13080622
Existing cite key: xiong2025-heavy-metals-infant-clothing

However, the regenerated routing audit still lists that source in data/evidence/routing_malformed.csv:

xiong2025-heavy-metals-infant-clothing,wiki/sources/xiong2025-heavy-metals-infant-clothing.md,advisory,,,ingredients,Source is missing optional routing-input fields; the routing layer falls back to broad scope where possible.

The source has a valid product route to [[products/infant-clothing]]. The missing field is ingredients: []. The PDF studies textile materials (cotton, polyamide, polyester, viscose, elastane and blends), but matching ingredient/material slugs do not exist in the current wiki, and this Codex lane is explicitly not allowed to create or stage wiki/ingredients/ pages. I did not invent a placeholder ingredient slug to remove the advisory row.

Per the user instruction to stop when the routing audit cannot confirm the source is absent from routing_malformed.csv, this run stopped here.
