aceitam apenas `username === cleitoncosta`.\n\n## O que a V0.2 adiciona\n\n- mensagens persistidas individualmente em `vault_messages`;\n- índice `vault_messages_fts` com SQLite FTS5;\n- ranking BM25;\n- tokenização Unicode com remoção de diacríticos;\n- busca multi-termo com AND + prefix matching;\n- fallback para a busca V0.1 quando não houver mensagens indexadas;\n- checkpoints persistentes em `vault_checkpoints`;\n- índice FTS dos checkpoints;\n- busca universal capaz de retornar conversas + checkpoints;\n- detalhe da conversa renderizado mensagem por mensagem quando o índice existe;\n- reimportação/reindexação idempotente para uma mesma conversa;\n- `vault_meta.schema_version = 0.2.0`;\n- self-test stateful com limpeza de fixture.\n\n## Duas rotas de memória\n\n### Histórico antigo\n\n`export oficial -> conversations.json -> importador no navegador -> conversa + mensagens -> FTS5`\n\n### Conhecimento novo\n\n`ChatGPT/conector Val Town -> checkpoint estruturado -> vault_checkpoints -> FTS5`\n\nIsso evita depender exclusivamente de novos exports para preservar decisões e estado de projetos daqui para frente.\n\n## Estado persistido no fechamento da V0.2\n\n- 3 conversas sintéticas compatíveis com export;\n- 10 mensagens de origem;\n- 10 mensagens individualmente indexadas;\n- 10 linhas no índice FTS das mensagens;\n- 970 B de conteúdo legado de conversa;\n- 1 checkpoint real sobre a prova da V0.1 no iPhone;\n- 0 fixtures de self-test restantes.\n\n## Evidência\n\n### PASS\n\n- V0.1 real no iPhone: login, importação, persistência, busca e abertura de conversa;\n- FTS5 disponível no SQLite do Val Town;\n- `Kernel timeout` -> conversa correta;\n- `NR-12` -> conversa correta;\n- `reconciliação` -> duas conversas relacionadas;\n- checkpoint encontrado por `export + oficial`;\n- controle negativo inexistente -> 0 hits;\n- reindex replay -> 2 mensagens continuam 2, sem duplicação;\n- replay FTS -> 2 linhas continuam 2;\n- self-test final -> `pass=true`;\n- self-test remove as próprias fixtures;\n- `index.ts` compila no runtime;\n- `frontend/components/App.tsx` compila no runtime;\n- visitante sem sessão continua redirecionado para autenticação.\n\n### Falha útil encontrada\n\nO primeiro self-test assumia incorretamente que uma busca por `kernel` retornaria somente a fixture. Como já havia uma conversa real de teste com esse termo, o self-test marcou FAIL apesar do sistema estar correto.\n\nCorreção: o validador passou a testar a presença da fixture dentro do escopo correto, sem assumir exclusividade global.\n\nLesson learned: **um teste pode falhar por hipótese inválida do próprio validador; negative controls e escopo explícito são obrigatórios.**\n\n### Ainda UNVERIFIED\n\n- parser contra export oficial real desta conta;\n- importação real de 25/50/100 conversas;\n- comportamento com um export muito grande no Safari/iPhone;\n- assets, imagens, PDFs, ZIPs e outros anexos do export;\n- busca semântica por embeddings/conceitos;\n- camada de armazenamento maior para histórico completo;\n- sincronização automática do histórico interno do ChatGPT.\n\n## Limites deliberados\n\nA V0.2 ainda preserva `conversations.content_text` por compatibilidade com a V0.1 e também mantém mensagens individualizadas + índice. Isso duplica parte do conteúdo e não é a arquitetura final para milhares de conversas.\n\nAntes da importação massiva, deve ser criada uma camada de armazenamento maior e o orçamento deve considerar tamanho físico real, não apenas `content_bytes` da tabela legada.\n\n## Próximos marcos\n\n1. Testar um export oficial real.\n2. Medir tamanho/quantidade real de chats e assets.\n3. Escolher storage gratuito maior para o histórico completo.\n4. Migrar o corpo das mensagens para arquitetura sem duplicação desnecessária.\n5. Adicionar projetos, entidades, relações e artefatos.\n6. Evoluir de full-text para busca híbrida/semântica sem depender da API da OpenAI.\n7. Criar interface/tool para outros agentes consultarem o Vault.\n8.

Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
