# Always scope Qdrant collection names by Embedding Model id

Every Model Corpus collection is named `{strategy}__{embedding_model_id}_collection`, including the default cloud model (`text-embedding-3-small`). This supersedes ADR-0018’s exception that left OpenAI on legacy unscoped names (`fixed_size_collection`). Uniform naming makes Admin labeling obvious for both Cloud and Local and avoids a special case that confused operators wiping/rebuilding corpora.

## Considered Options

- **Always include model id** — chosen; clear for cloud and local
- **Keep legacy unscoped names for default cloud only** — ADR-0018; rejected going forward after a from-scratch rebuild

## Consequences

- Process/query create names like `fixed_size__text-embedding-3-small_collection` and `fixed_size__nomic-embed-text-v2-moe_collection`
- Old unscoped collections are not written anymore; Admin still labels them as legacy default-cloud if they remain until deleted
- Operators wiping for a clean slate should delete legacy collections before re-processing
