One word everywhere: ReplyPier in UI copy, package and image names, the replypier.site domains (app/api/docs/help), REPLYPIER_* settings and the --rp-* design tokens. - public widget API is window.ReplyPier with replypierId / replypierBaseUrl / replypierConfig / replypierToken, loader at webclient/replypier.min.js; both bundles rebuilt from source - NOTICE, llms.txt, CONTRIBUTING, HELP_CENTER_INFRA and the demo runtime config rewritten; the demo config ships no third-party keys - migration adds the ReplyPier managed model value to the AI model enum - local compose project, database, role, volume and Docker network carry the same name

The local embedding model, loaded once per process.
|
|
|
|
agno's ``FastEmbedEmbedder`` builds a new ``TextEmbedding`` (an ONNX session)
|
|
inside every ``get_embedding`` call — about 1.5 s of model loading around a
|
|
7 ms embedding. One row per page hid that; one row per chunk would not.
