Pablan, as it stands

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.

+"""Gate on the two message rules that cannot be caught at runtime.
+
+1. **Every locale carries every key.** Paraglide falls back to the base
+   locale for a missing message, which means an untranslated string ships
+   silently as German inside an English interface. A missing key is a build
+   failure here instead.
+
+2. **No em or en dashes in UI copy.** They are hard to type, inconsistent
+   across the app when hand-written, and in German they collide with the
+   Gedankenstrich convention. Commas, colons or a second sentence do the
+   job. Prose in docs/ and comments is unaffected: this only reads the
+   message files.
+
+Run by `make lint`, so both rules hold for every route the migration
+touches rather than only where someone remembered.
