Subject: [PATCH] Keep searchable text only in knowledgebases

Every bot file was chunked into bot_file_chunks and embedded into
bot_file_vectors, and uploads kept their extracted text in
media.text_content, which together took most of the database. Bot
files are no longer indexed: bots find them by name or path with
list_files and read them with read_file, and search_files, ingest_file
and the files modal's re-read button are gone. Attachments keep no
text; a reply reads a document from the file. Only knowledgebase
documents keep text.

The schema drops both tables and the ingest columns. At boot,
dropStoredFileText removes what older versions stored (file jobs,
upload text) and vacuums once much of the database is free. The
media:prune-text script it replaces is removed.

Reach via `grabStorageScopes`; paths via `resolveBotPath` (no absolute, `..`, NUL, symlink escape); quota checked by `assertStorageRoom`.
 - Tools in `src/harness/tools/storage/` (every run). `attach` puts a file on the reply. `grabConversationFiles` must list the **whole** folder tree, or nested `[file:ID]` refs render dead. A workspace run saves to the bot's own folder unless it picks the workspace's, so a chip in a workspace conversation looks up both (`api/admin/bots/files?file_id=` with `bot_id` and `workspace_id`).
 - `import_file` copies from a computer through the sandbox's streaming `GET /v1/file/download`, **never through its shell** (`/v1/shell/exec` caps output at ~30K chars and silently truncated imports). Size read first, `change_policy=abort`, length checked.
-- Ingestion: chunks + embeddings into `bot_file_chunks` / `bot_file_vectors` (vec0), worked by `src/file-ingest/`; without an embedding model search falls back to words and says so. sqlite-vec limits: metadata columns are NOT NULL; side-car columns can't be filtered with `MATCH` (filter in code). **Never pass `--vector` to `bunx bun-sqlite schema` in `entrypoint.sh`** (wipes vectors on boot). Changing `AppData.EmbeddingDimensions` needs a manual `--vector` run and a re-ingest.
+- **Only knowledgebases store text.** Bot files and uploads are never indexed and keep no extracted text (`media.text_content` only for knowledgebase documents); bots find files by name or path (`list_files` `search`) and read them with `read_file`, and the Files searches match names only. Text that should be searchable goes in a knowledgebase. `dropStoredFileText` clears what older versions stored, at boot, and vacuums when much of the file is free.
 - **Foreign keys are off per connection** unless `enableForeignKeys` ran (only `src/server.ts` does). Scripts never fire `ON DELETE CASCADE`, so **any helper that deletes a parent row must delete its children explicitly** (as `deleteBotFile`, `purgeStorage`, `deleteSkill` do). A leftover child fails the next `bun run db:schema` with a foreign key violation.

 A fourth extension kind (`ExtensionTables.knowledgebase`): `knowledgebases` given per bot (`bot_knowledgebases`), per workspace (`workspace_knowledgebases`) or every bot (`all_bots`), through the same add/remove/access/default paths as skills (coordinator extension tools leave them out). 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. UI: Settings > Knowledgebases (super admin edits and fills; admins set access), a Knowledgebases group on bot/workspace settings, and the composer's own button beside Tools (`ComposerToolsModal` with `composerKnowledgebasesCopy`). Deleting one deletes its documents' vectors, chunks, media and links explicitly.

Links built only by `storageSpecHref`. Deletion stays in the chat's files modal and bot tools.

 You have a folder of your own, kept with the app (not on a computer), and it stays between runs and conversations.
 
 - list_files shows what's in it; read_file opens one (by its [file:ID] ref or path); write_file saves a text file, make_pdf a PDF, generate_image an image. Move and delete with move_file and delete_file when something is out of date, so the folder stays useful.
-- Text files are chunked and searchable as soon as they're saved. search_files finds the passages that answer a question, by meaning when an embedding model is set and by words otherwise. Search your files before saying you don't know something they may hold, and when the user asks about a document they gave you.
-- Uploaded files land in the same folder, under uploads/ (uploads/2026-10/logo.png), so what the user sent you earlier is searchable later too.
+- Files are found by name or path, never by what's in them: list_files with "search" matches names and paths, then read_file reads the one you want. Look for a file and read it before saying you don't know something it may hold, and when the user asks about a document they gave you. Searching by content is what knowledgebases are for; your files aren't indexed.
+- Uploaded files land in the same folder, under uploads/ (uploads/2026-10/logo.png), so what the user sent you earlier is there to list and read later too.
 - A picture can be set from a file: set_picture makes a file your own avatar, and update_workspace sets a workspace's. Both take the [file:ID] ref, so a logo the user sent you is usually ready to go: list_files for it, then set it. An SVG or another kind of file is turned into a PNG first. Its picture is free to change and never removes your file.
 - A file and a folder are two different refs, and you never guess which one from the name:
-    - A file you saved is a [file:ID] ref (from write_file, list_files, search_files or import_file). The user sees a chip that opens the file.
+    - A file you saved is a [file:ID] ref (from write_file, list_files or import_file). The user sees a chip that opens the file.
     - A folder is a folder ref, e.g. ${ownFolderRef({ bot_id })}: the user sees a chip that opens that folder in Files, and nothing is downloaded. Use the volume of the folder you mean ("bot" for your own, "workspace" for a workspace's shared one).
     - Never write a path as plain text and expect the user to find it; never write a [file:ID] ref for something that is a folder.
     - Write refs as they are, never in backticks or a code block: inside code they show as plain text, not a chip.
 - A file you only described is not saved. Save it first, then say it's saved.
 - Save what the user will want before the long tail of a run. A step limit ends a run where it stands: write the report first with write_file (or copy it off the computer with import_file), then carry on verifying.
-- One copy of a thing is enough. Before you write or import something, list_files (or search_files) for it: if it's already there, update it (write_file over the same path) instead of saving a second copy under a new name. Never split a file into parts unless the user asked for parts.
