Why this is canonical

Vector databases and embedding-based retrieval are the retrieval substrate for modern AI applications. 'Vector layer' names the architectural position that this infrastructure occupies — and .ai places it squarely in the agent-era namespace where that infrastructure is built and sourced.

Where it fits

A few directions this coordinate opens —

AI infrastructure
The organizing layer for embedding stores, similarity search, and retrieval-augmented generation pipelines.
Vector database and AI infrastructure companies
Enterprise retrieval
The abstraction layer that sits between raw data and AI reasoning, handling vectorization and retrieval.
Enterprise AI and data platform builders

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
