Two bugs combined to make the chat reply with only cards and no prose: 1. SQL trigger rollup_session_stats was failing with "column reference total_cost_usd is ambiguous" because the UPDATE on public.profiles had a FROM public.chat_sessions clause and both tables expose that column. Persistence of every user message died at this point — sessions were created in the DB but had message_count=0 forever. Applied SQL fix that qualifies columns with p./s. aliases (production DB updated; ALTER FUNCTION run live, not yet codified in a migration file). 2. The free-tier model (nemotron-3-super:free) spent all 5 tool-loop turns on hybrid_search calls and never wrote any prose, returning content_len=0. Added a forced-synthesis pass in openrouter.ts: when the loop exits with empty assembledText but the model did call tools, we send ONE final turn with tools omitted from the request payload and a user message instructing the model to answer in 3-8 sentences citing chunks. openrouterStreamCall now accepts a `withTools` opt so the synthesis call can disable tool calling entirely. Verified end-to-end with the actual user query "O que os astronautas viram? Quem foi que viu?" on /d/nasa-uap-d6-apollo-17-...: - content_len: 0 → 947 chars (real synthesis citing Schmitt) - artifacts: 44 preserved - assistant message persisted with tool_calls + citations columns |

web — Disclosure Bureau Next.js app
Next.js 15 + React 19 + Tailwind + Supabase + assistant-ui.
Quick start (local dev)
# 1. Install deps
npm install
# 2. (Optional) Start local Supabase
# Requires Docker. Skip if pointing at remote Supabase.
npx supabase init # first time only — creates supabase/ folder
npx supabase start # spins up Postgres/GoTrue/Storage on :54321
# 3. Configure env
cp .env.local.example .env.local
# Edit .env.local — paste local Supabase keys (printed by `supabase start`)
# 4. Apply migrations
psql postgresql://postgres:postgres@localhost:54322/postgres \
-f ../infra/supabase/migrations/0001_chat_schema.sql
# 5. Start dev
npm run dev
# http://localhost:3030
Without Supabase
The app degrades gracefully if Supabase env vars are unset:
- Wiki browsing works (read-only from filesystem)
- Auth bar shows "auth: disabled (dev)"
- Chat bubble shows "Auth not configured"
Useful for quick UI work without spinning up Docker.
Production (Coolify on VPS)
See ../infra/coolify/. Stack:
- Coolify orchestrates everything
- Supabase self-hosted:
db.disclosure.top,studio.disclosure.top - Next.js:
disclosure.top - Meilisearch (shared):
search.disclosure.top - Imgproxy (shared):
img.disclosure.top - Caddy: TLS + reverse proxy (built into Coolify)

Tech notes
- No RAG: chat agent reads markdown directly. Wiki-link traversal substitutes for vector search.
- RLS-first: Supabase Row Level Security enforces "user sees only own sessions" at the DB layer.
- Magic-link auth: no passwords. GoTrue handles email delivery.
- Anti-abuse: per-user budget cap (default $5) + daily message quota (default 100) enforced via
check_budgetRPC before each Claude call.
Cost
Each chat turn costs ~$0.005-0.05 depending on context size (mostly Haiku $1/M input, $5/M output).
