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.

"""Per-role endpoint configuration, edited in the admin UI.
|
|
|
|
One row per model role. The rows are created once, at first start, from
|
|
the `PABLAN_CHAT_*` / `PABLAN_UTILITY_*` / `PABLAN_EMBEDDING_*` environment
|
|
variables; from then on **this table is the truth** and later `.env`
|
|
edits are ignored (see docs/architecture.md, "bootstrap, then DB").
|
|
|
|
The `*_from_env` flags record where each field's current value came
|
|
from, so the UI can say "taken from .env" or "changed here" per field
|
|
and offer a reset. They are not a fallback mechanism: the value itself
|
|
always lives in the column next to them. Tracking the provenance
|
|
explicitly beats comparing against the current environment, which would
|
|
mislabel every field the moment someone edits `.env` after bootstrap.
|
|
|
|
The api_key is stored in plaintext because it has to be replayed to the
|
|
endpoint on every call — there is nothing to compare a hash against.
|
|
It is never returned by the API and never logged.
