Self-hosted knowledge management for SMEs: a split-screen Markdown editor whose sections an LLM refines while you write, and RAG question answering over the documents that result. FastAPI + Postgres/pgvector on the back, SvelteKit on the front, everything OpenAI-compatible and self-hostable. Squashed into a single commit; the development history stays local.

"""The effective system prompts, as the process sees them.
|
|
|
|
Prompts default to code (`app/prompts/defaults.py`); an admin may override any
|
|
of them in `prompt_settings`, applied without a restart. This mirrors the LLM
|
|
settings override pattern, with two simplifications: the reset target is the
|
|
code default (prompts have no `.env` layer), and there is no bootstrap — a
|
|
missing row simply means "use the default".
|
|
|
|
`get_prompt` is called while rendering a prompt, so it reads a module-level
|
|
cache rather than awaiting a query. The cache is filled at startup and refreshed
|
|
on every admin write. Single-process by design (`--workers 1`); a multi-worker
|
|
deployment would need a notification channel.
