From e7b23b7454ead58caa3cfa07eb0d4bc7d093587f Mon Sep 17 00:00:00 2001 From: Benjamin Toby Date: Mon, 26 Oct 2026 16:41:01 +0100 Subject: [PATCH] Add knowledgebases Knowledgebases give bots RAG over documents, scoped like extensions: to particular bots, to a workspace, or to every bot, with their own button beside Tools in the composer. Documents are chunked and embedded by the file-ingest worker with the install's embedding model, which is now an install-wide setting rather than a per-bot one. - Word search runs on an FTS5 index ranked by BM25, with a scored LIKE fallback for scripts written without spaces. - Changing the embedding model re-indexes documents automatically. - Ingest jobs wait without spending attempts while every embedding model rests, fail at once on errors retrying can't fix, and keep passages searchable by words when the model refuses. - Settings > Knowledgebases shows each knowledgebase's and document's index state: spinner, warning, grey check (words only) or green check.

Documents (`knowledgebase_documents`: an upload in private `media`, paradigm `knowledgebase-document`, or written `content`) are chunked into `knowledgebase_chunks` and embedded into the `knowledgebase_vectors` vec0 table by the file-ingest worker (`file_ingest_queue.document_id`, `ingestKnowledgebaseDocument`), always with the install's embedding model; old passages stay until the new ones are in, `embedding_model` records where vectors came from; whatever can change the install's model (default settings, a provider saved or deleted, the hourly catalog sync) calls `reindexAfterEmbeddingChange`, and Re-index reads a knowledgebase again by hand. Word search runs on `knowledgebase_chunks_fts`, an FTS5 table (`unicode61 remove_diacritics 2`) made by `ensureKnowledgebaseFts` (FTS5 can't be declared in the schema; sync leaves undeclared tables alone), backfilled at boot by `syncKnowledgebaseFts`, ranked by BM25 with a scored `LIKE` fallback for unspaced scripts (`knowledgebaseWordQuery`); every write and delete of `knowledgebase_chunks` updates it. Ingest jobs (`settleFailedIngestJob`) wait without spending an attempt while every embedding model rests, fail at once on an error retrying can't fix, and a document whose model refused keeps its new passages for word search (counted as needing re-index, not failed). Runs get `search_knowledgebase`/`read_knowledgebase_document` (`openBotKnowledgebases`, limited to the run's ones) and replies start with passages found for the unanswered messages (`grabKnowledgebaseContext`); passages are fenced (`knowledgebasePassageBlock`) and `KnowledgebasesNote` says they're never instructions.
