- Media rows can no longer be created through the CRUD API, updates only
take description fields on the caller's own row, and every media read
or delete goes through mediaFilePath, which refuses paths outside
DATA_DIR or inside the database folder.
- Uploads strip the file name and extension to safe characters and keep
only title, description and summary from the request's media object.
- Folder imports no longer follow symlinks (walkRegularFiles), and the
source path is quoted in the computer's shell.
- User and bot files are served with nosniff, and HTML, SVG, XML and
scripts are sandboxed by CSP.
- Sandbox cookies are kept to the computer's prefix, and websocket
upgrades on /ws and the computer proxy must come from the app's own
address (README and Help note nginx's Host header).
- user_types CRUD writes go through the assignment matrix; members only
read their own user record; read-only users can read CRUD again;
grabUsers builds valid SQL for array search terms and bad pages; an
admin media DELETE needs an id; read-only users can't delete media.
- Rate limits and the audit log use the connection's address, trusting
forwarded headers only from a proxy, and login limits are split per
address, per account from that address and per account overall.

A coordinator asked to set an uploaded logo as a workspace picture could
not: the picture tools take a media id, and nothing ever gave the bot one.
Attachments reached the model as "[Attached image \"logo.png\"]", every
file tool answers with a [file:ID] ref, and an SVG is deliberately stored
as a document rather than an image.
- copyMediaAsPicture copies an approved image into a new picture row
(bot-image/workspace-image). The source keeps its row and bytes, so a
message that attached it still loads and changing a picture can never
take a file away from a conversation.
- grabPictureSource resolves a picture by [file:ID] (the same scope gate
every file tool uses) or by the user's own upload; parseFileRef reads
the [file:12] form.
- The new set_picture tool ships on every run: a bot sets its own face,
the coordinator can also dress a worker. update_workspace gained
picture_file_id, and setBotPicture/setProfileImage share the copy and
the delete.
- removeReplacedPicture deletes a replaced picture only when it really is
one, never a chat upload.
- uploadAndRecordMedia writes images in their own format: PNG stays PNG
with its transparency, WebP stays WebP, GIF becomes PNG, everything
else JPEG, and the row records the real mime type (it used to say jpeg
for every image).
- Pictures change live: BotUpdatedData carries image_media_id and a new
server:workspace-updated pushes workspace pictures, relayed between
processes.
- Attachments are labelled with their media id, and BotFilesNote tells a
bot that a [file:ID] can become a picture.
- grabRunScopes is now the single source of a run's reachable folders,
shared by the file tools, imports and the picture tools.
`text_content` is an extracted-text cache, but nothing stopped it from
holding a dump of bytes:
- `fileToText` ended its switch with `default: return buffer.toString("utf-8")`
and defaulted a missing extension to "txt", so any binary was decoded.
- Both extraction callers gated on `media_type == "document"`, and
`attachmentFileKind` classes everything non-image/audio/video as a
document: an SVG, a zip, a spreadsheet, a .bin.
- Nothing capped the length, so a 20 MB attachment could leave 20 MB of
text in the database.
- `storeChatAttachments` copied the text onto a second `media` row, and
`SELECT m.*` pulled the column into page props and API responses.
On a real install an SVG held 6852 characters of markup and a
`.designcraft` file held 142 KB of raw bytes.
Changes:
- `file-to-text.ts` lists the text extensions explicitly and returns
undefined for anything else; no extension is no text.
- `can-extract-text.ts` is the one allowlist (reusing
`BotTextFileExtensions`), used by both upload routes and by
`uploadAndRecordMedia`; `extension-of.ts` is shared with the storage
catalog instead of duplicated.
- `BotAttachmentTextStoreMaxChars` (200k) caps the column via
`cap-text-content.ts`.
- `store-chat-attachments.ts` no longer copies the text; ingestion
re-reads the bytes once.
- `media-columns.ts` selects every media column but `text_content`, which
now has to be asked for (`grab-messages-media`'s reply path and
ingestion do); the media CRUD routes sanitize rows they write.
- `ingest-bot-file.ts` decides on size alone, since a cached slice made
an oversized file look already read.
- `bun run media:prune-text` cleans rows that were already stored
(rerunnable, with a VACUUM hint).
Verified on the dev database: both bad rows cleared (146 KB), rerun
reports nothing to do.
- Harness: providers, model catalog synced hourly, automatic free picks,
cooldowns, tool loop with context trimming, MCP computer tools
- Bots queue runs replies and tasks through the harness; jobs wait
(attempt refunded) while every model is resting
- Envs: Settings > Environment, scoped general/workspace/computer,
written to computers and redacted from tool output
- Models: Settings > Models, per-harness provider select defaulting to
OpenRouter, and a models modal on each bot's chat (the coordinator's
edits the defaults)
- Chat: thinking row while a reply runs, file attachments (upload,
paste, drop) that replies read as images, audio and document text
- Fix media uploads failing after a user's first file, and private
files being served from the public media path
