docs(embeddings): the chunk offset column is <column>_offset, not _offsets (#2170) Every page that documents bring-your-own chunked embeddings named the required offset column '<column_name>_offsets'. The runtime looks for '<column>_offset': offset_col! in runtime-search generates '{col}_offset', ChunkedSearchIndex ::chunking_offset_col formats the same, and base_col strips '_offset'. The consequence is silent. EmbeddingTable::base_table_has_embedding_column looks the column up by that exact name and, unlike the two neighbouring early-returns, logs nothing when it is missing - it just returns false, so the column is not treated as precomputed and Spice re-embeds it from scratch. A user who followed the docs pays for embeddings they already had and gets no diagnostic explaining why. The vector-search page already contradicted itself: its 'describe sales' example for the chunked case shows 'address_offset', matching the code, one section below the constraint that asked for '_offsets'. Swept all 11 doc sets and all three page types that carry the claim.
