Working chat: auth, connections, streaming, folders
LLeMbas now runs end to end. Register, add an OpenAI-compatible connection, and hold a real streaming conversation organised into folders. Verified against the local llama-swap instance. Streaming is the one genuinely tricky part. Sending a message returns two HTML fragments -- the user bubble and an empty assistant bubble carrying an sse-connect -- and that attribute is the ONLY thing that starts a generation. Rendering an incomplete assistant message as a streaming shell falls out of the same template, which means loading a page whose last reply never finished simply picks it up again. Details worth knowing about, each commented where it matters: - SSE payloads are split across several data: lines. A raw newline in one data: line truncates the event, which shows up the first time a model emits a code block. - Markdown is rendered server-side by the same helper for both the page and the final streamed frame, so the two cannot disagree. The fence renderer is replaced outright rather than using markdown-it's highlight option, which re-wraps output in a second <pre>. - escape_text is html.escape, not nh3.clean_text: it escapes character by character, so escaping stream chunks separately equals escaping the whole string. - The stream opens its own session via session_scope(); it outlives the request handler and the dependency-scoped session may be closed. - Deleting a folder keeps the chats inside it (FK is SET NULL). Losing a conversation to a mis-clicked folder delete is unforgivable. - Login failures use one message for "no such account" and "wrong password" so the form cannot enumerate registered addresses. Also adds deploy/ for the gamebox install at https://chat.lan: system unit, nginx vhost with buffering off (buffering on turns streaming into one lump at the end), and install/update scripts following the same service-user and /srv bind-mount conventions as llama-swap and comfyui. 70 tests, ruff clean.
