database_query passed model-written SQL straight to a connection that commits. The
corpus reaches the model's context, and in a parliament anyone able to speak can get
text into the corpus, so that SQL has to be treated as untrusted input.
Two layers now apply. Statements must begin with SELECT or WITH, and multi-statement
payloads are rejected — that is how a write gets smuggled in behind a leading SELECT.
Then the query runs inside SET TRANSACTION READ ONLY, so PostgreSQL rejects writes
itself even if the first check is wrong. Verified both independently: five attack
shapes refused by the guard, and INSERT/DROP still refused when the guard is bypassed
entirely and the database layer is called directly.
share_insight gets the same treatment. It re-executes SQL stored in saved
conversations, which is no more trustworthy than freshly generated SQL.
Neither layer replaces running against a SELECT-only role, and SECURITY.md still says
so — it now describes what the application does rather than what it fails to do.
Tool rename completed as a clean break, no aliases, since there are three users and
six sessions to preserve: arango_search -> search_speeches (it has queried Postgres
since the Arango migration and the name was pure debt), search_motions ->
search_documents, fetch_motion -> fetch_document.
Also renamed fetch_documents -> fetch_speeches. It fetches speeches despite the name,
and sitting next to the new fetch_document it was a trap the model would fall into.
Note for anyone with an MCP client configured against the old names: riksdagen_mcp
exposes these, so the names it advertises have changed.

Sixteen system prompts lived as module-level string constants across chat.py,
board.py, synthesis.py, trip.py and llm_tools.py. They are the main thing a fork
for another parliament has to rewrite, and editing them meant editing Python.
They now live under prompts/sv/ as Markdown. Placeholders use string.Template
($name), not str.format: three of these prompts embed literal JSON braces that
str.format raises on, and safe_substitute leaves an unknown placeholder alone
rather than killing a live chat turn over a typo.
Technical configuration that had leaked into the prompt text is now templated:
websearch_to_tsquery('swedish', ...) became '$fts_config', "Answer in Swedish"
became "Answer in $answer_language", and the åäö preservation rule became
$preserve_characters. Domain vocabulary from parliament.yaml is available too, so a
prompt can say $speech_plural and read naturally in any language.
PROMPTS_RELOAD=1 re-reads the files per call, so prompt iteration no longer needs
a server restart.
The prompts themselves stay Swedish. That is the intended design: a fork writes
prompts/<lang>/ in its own language, and the loader falls back through
<lang>/ -> shared -> en/.
Verified by snapshotting all sixteen constants before the move and asserting
equality after: 16/16 render byte-identically, including after parameterization —
which is what proves the templating substitutes exactly what was there before.
tests/test_prompts_golden.py keeps that guarantee going forward.
