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
Fase 3 onda 2 — entity synthesis at scale:
- scripts/synthesize/20_entity_summary.py: queries DB for entities with
total_mentions ≥ threshold + top-K verbatim chunk snippets via
entity_mentions JOIN, prompts Sonnet (Holmes-Watson voice, bilingual),
writes narrative_summary EN+PT-BR + summary_status=synthesized.
Ran on 187 candidates (mentions ≥ 20) → 158 OK · 1 err · 29 skipped (no
snippets). Combined with anchor curation: 20 curated + 158 synthesized
= 178 entities with real narrative (vs 0 a day ago).
Fase 4 — chat with typed artifacts + persistence:
- lib/chat/agui.ts: AG-UI v1 typed Artifact union (citation, crop_image,
entity_card, evidence_card, hypothesis_card, case_card, navigation_offer)
alongside the existing event types.
- lib/chat/tools.ts + openrouter.ts: hybrid_search emits up to 6
citation + crop_image artifacts per query. Provider collects them and
returns in done.artifacts so the route can persist.
- api/sessions/[id]/messages: persist artifacts to messages.citations.
- components/chat-bubble.tsx: ArtifactCard renders inline cards (citation,
crop_image, entity_card, navigation_offer) for streamed and persisted
messages. activeId now persisted in localStorage so navigation between
pages keeps the same conversation. New sessions are lazy (only when user
has zero). loadMessages hydrates tools + artifacts from server. CRUD UI:
rename (✎) + archive (🗑) buttons per session in the list.
Home search:
- doc-list-filters: input now fires hybrid_search (rerank=0 for speed)
in parallel with the local title filter; chunk hits render above the doc
grid with snippet + score + classification.
- api/search/hybrid: accept ?rerank=0 to skip the cross-encoder (1.3s vs 60s).
Auth flow:
- infra: SMTP_HOST=mail.spacemail.com:587 + DMARC published; mail now lands
in inbox. GOTRUE_MAILER_AUTOCONFIRM=false (real email verification).
- kong.yml: proxy /auth/callback on api.disclosure.top → web:3000 so PKCE
email links don't 404 at the gateway.
- web/app/auth/callback: handle both ?code= (OAuth) and ?token=&type=
(PKCE); redirect to the public site host before verifyOtp so the session
cookie lands on the right domain.
Audit deliverables:
- .nirvana/outputs/disclosure-bureau/.../systems-atelier/: 5 docs (code
analysis, tech debt, discovery brief, system arch, 5 ADRs) authored by
sa-principal that produced this roadmap. Kept in-tree for traceability.
