Tests prove that a query with *no* org filter still returns only the bound tenant's rows and that cross-tenant writes are rejected by PostgreSQL. +* Platform-level audit events (`org_id IS NULL`) are write-only from request contexts. + +## Authorization model + +Two layers, both enforced server-side on every request: + +1. **Capabilities** (`kb.upload`, `db.query`, `admin.audit`, …, 55 total) come from roles assigned to a user directly or via a team, at organisation or workspace scope, with optional expiry. Predefined roles: Owner, Admin, Security Administrator, Workspace Admin, Knowledge Base Manager, Data Source Manager, Developer, Analyst, Standard Member, Read-Only User; custom roles cannot exceed the creator's permissions or rank (escalation prevention). API keys are capped to their scopes. +2. **Resource privileges** (`none < read < write < manage`) on knowledge bases, documents, database connections and agents: implicit rules (owner, `kb.access_all`, KB visibility `org`/`workspace`) combined with explicit grants to users, teams, departments, roles, workspaces or the whole organisation. **Deny grants cap the privilege and beat every allow, including admin access.** Grants can expire. Documents in `restricted` ACL mode additionally require a document grant. Database grants can be narrowed to specific tables. + +`Authorizer.access_scope()` computes, once per request, the readable knowledge bases plus denied and restricted-allowed documents. That scope is compiled into the SQL of every retrieval query, so unauthorized chunks are never fetched, scored, cited, cached or exported. Past citations are re-authorized whenever a conversation is viewed, previewed, shared or exported. + +Platform administrators have **no** tenant content access. An organisation owner can grant a time-boxed, read-only support window; every request made under it is audited. + +## Ingestion pipeline + +`upload → spool (size limit, SHA-256) → detect (extension + magic bytes, secrets/executables rejected, zip-bomb checks) → store (object key per tenant) → Document + DocumentVersion → job` + +The `ingest_document` job: parse → normalise (NFKC, control/bidi characters, whitespace) → language detection → auto-tags → prompt-injection screening → chunk → embed in batches with progress events → atomically replace the document's chunks/embeddings → derive datasets (Parquet + profile) for tabular files → emit `document.ingested`, `index.updated`, `pipeline.completed`. + +Parsers keep citation locators: PDF page, heading trail, Excel sheet + row range, slide, code line range, notebook cell, EPUB chapter, source URL. Duplicate uploads (same hash in a KB) are detected; re-uploading with `replace_document_id` creates a new version and re-indexes incrementally. + +## RAG engine + +Separate components: chunking (structure, markdown, fixed, recursive, token, sentence, semantic, table-aware, parent-child), embeddings (hashing baseline, OpenAI/Azure/compatible, Cohere, Voyage, Hugging Face/TEI, Ollama, local ONNX via fastembed, custom HTTP), index, retrieval, reranking, context assembly, generation, citation verification, evaluation. + +* **Vectors** live in `chunk_embeddings(embedding vector)` without a fixed dimension; per-dimension partial HNSW indexes (`(embedding::vector(768)) WHERE dim = 768`) let each knowledge base choose its own model. Dimension mismatches are rejected. +* **Sparse retrieval** is real Okapi BM25: PostgreSQL full-text (GIN, prefix matching for morphology) selects candidates; document frequencies, corpus size and average length are computed exactly over the *authorized* scope, so scores never depend on hidden documents. +* **Hybrid** fusion: reciprocal-rank fusion (default) or weighted. **Reranking**: a feature reranker (dense similarity, normalised BM25, IDF-weighted term coverage, proximity) — or Cohere / cross-encoder when configured. **MMR** diversification, **pseudo-relevance-feedback** query expansion (offline), LLM multi-query, parent-child expansion and contextual compression. +* **Conversational RAG**: follow-ups are condensed into standalone queries (LLM, or term carry-over offline). +* **Structured retrieval**: analytic questions over KBs with datasets or live database connections are routed to Text-to-SQL; the query result becomes a citable source. +* **Grounding**: sources are wrapped as untrusted data, instruction-like spans are neutralised, the model must cite `[S#]`; invented labels are stripped and reported; each cited sentence is checked for lexical support; insufficient evidence (IDF-weighted coverage + calibrated dense similarity) produces an honest refusal without calling the model. Without a configured model the engine produces a clearly labelled extractive answer; if the model fails before producing output, it falls back to extractive. + +## Text-to-SQL + +LLM generation (with one self-correction round) → **validator** (single read-only statement; no DDL/DML/session/admin nodes anywhere in the tree; dangerous functions blocked incl. `pg_sleep`, file readers, `set_config`; table/column allow-lists from the admin selection ∩ the user's grant constraints; `SELECT *` expanded to allowed columns; admin row filters injected by wrapping tables in filtered subqueries; hard `LIMIT`; join limits) → approval queue for sensitive tables or cross joins (executed with the *requester's* permissions, never self-approved) → execution in a read-only transaction with a server-side timeout (live DBs) or an in-memory DuckDB sandbox with external access disabled and configuration locked (datasets) → explanation and chart suggestion → `sql_query_logs`. + +## Background processing + +A PostgreSQL-backed queue replaces Celery+Redis (decision: transactional enqueue with the data it processes, one less service). Workers claim jobs with `FOR UPDATE SKIP LOCKED`, wake on `NOTIFY rag_jobs`, run handlers inside **tenant sessions** (RLS stays on), retry with exponential backoff + jitter, dead-letter after `max_attempts` with a notification, and recover stale leases. Idempotency keys prevent duplicate work. A scheduler (guarded by an advisory lock, one per cluster) enqueues scheduled syncs. `JOB_BACKEND=embedded` runs the worker inside the API for single-node installs. + +## Real-time events and the Connections command center + +`activity_events` is the source of truth; events are published after commit via the in-memory bus or Redis. `/events/stream` is an SSE endpoint, resumable with `Last-Event-ID`, filtered per subscriber by permission (connection, KB and job visibility). `/connections/graph` builds the ecosystem graph only from rows the viewer can see (organisation → workspaces → knowledge bases; sources → ingestion pipeline → knowledge bases → embedding models → pgvector → RAG engine → AI models → agents; live-query databases → RAG engine), with node status derived from health checks, sync runs and jobs, grouping for large graphs, and summary/health aggregates.

Git history of the reused modules is preserved (`git mv` into `backend/app`). + +### Added (late in the 3.0.0 cycle) +- Ten SaaS integrations: Google Drive, OneDrive, SharePoint, Dropbox, Notion, Confluence Cloud, Slack, Microsoft Teams, GitLab and email (IMAP), with an OAuth 2.0 framework (authorization code + PKCE, signed single-use state, encrypted token storage, refresh with persisted rotation) and token alternatives for Notion, Confluence, Slack, GitLab and IMAP. GitLab is `tested` (live check against a public gitlab.com project); the others are `beta`, and OAuth-only vendors show "needs setup" until their `OAUTH_*` app is configured. Responses served with `Content-Encoding: gzip` no longer fail in the website/sitemap/RSS fetcher. +- Organisation security policy is now enforced: "require two-factor authentication" blocks members (and their API keys) without MFA, and "session lifetime" forces re-sign-in after the configured number of days. Admins must have MFA themselves before requiring it. Blocked members see an in-app gate that leads to the fix. +- Organisation settings are validated per section (unknown keys, ranges, https-only logo URLs). +- Branding is applied app-wide: the accent colour drives the `--accent` token (lightness clamped per theme) and the logo appears in the organisation switcher. +- "Porcelain / Graphite" design system (`docs/DESIGN.md`): Geist / Geist Mono / Instrument Serif type, warm light and neutral dark themes, raised content panel shell, org switcher and account menu in the sidebar, breadcrumb top bar, redesigned overview, sign-in, command palette and every page. +- Anthropic provider moved to API version `2026-10-21`: sampling parameters are no longer sent (they are rejected on every model), an optional `effort` setting maps to `output_config.effort`, and a `refusal` stop reason surfaces as a provider error so the engine falls back to an extractive answer. +- OpenAI provider works with current models: `max_completion_tokens` on OpenAI's own API (reasoning models reject `max_tokens`; compatible servers keep it), a one-time retry without `temperature` for models that accept only the default, and an updated suggested-model list. +- Refusal detection is one shared function (`grounding.is_refusal`) that recognises common phrasings ("The provided sources don't include …"). Previously an uncited decline in that form was withheld under the strict policy and replaced with unrelated passages. +- RAG evaluation harness runs hosted providers (keys from the environment or `--env-file`, never printed) and records answers and token usage. +- Live model discovery: each provider's model list comes from its API (OpenAI-compatible `/v1/models`, Anthropic Models API, Gemini `models.list`, Ollama), is stored as suggestions and refreshed daily, so new models appear without a release. Settings → AI providers fetches it for every provider type. +- Platform model fallback supports Anthropic as well as OpenAI (`DEFAULT_PROVIDER`, `ANTHROPIC_WORKSPACE_ID`), respects the organisation's provider allow-list, and is shown to organisations in AI settings. `scripts/dev.py --env-file` loads only the model-provider keys for local development. +- The demo seed no longer registers a local Ollama provider unless asked (`--ollama`). +- Agent runs no longer fail with HTTP 500 when a model sends malformed tool input; the error is fed back to the model. +- Deleting a database connection expires its pending SQL approvals. +- `backend/var/` (embedded PostgreSQL data, uploads, SQLite sources) and frontend build output are gitignored. +- Approved agent tools resume the paused run in the background with the requester's permissions (sources re-authorized), notify the requester, and update the run view live; requesters can withdraw pending approvals; `GET /approvals/{id}`. +- Playwright end-to-end suite (`frontend/e2e`, `npm run test:e2e`) covering sign-up, knowledge bases, chat with citations, access control, the MFA policy gate, the Connections map, the shell and mobile layouts; CI job using a pgvector service container. See `docs/TESTING.md`. +- CI backend and E2E jobs use a PostgreSQL 16 + pgvector service container; `devdb.py` derives connection URLs from parsed conninfo (Unix sockets on Linux/macOS); `dev.py` honours an explicit `DATABASE_URL`; `REGISTER_RATE_LIMIT_PER_HOUR` is configurable. +- Accessibility: every sign-up, invitation, password, two-factor and organization form label is linked to its input. The overview no longer scrolls sideways on phones. +- Renamed the project to **Knowledge Intelligence** (repository `knowledge-intelligence`, package names, compose project and images, crawler user agent). +- `IMPLEMENTATION_STATUS.md` and `docs/RAG_EVALUATION.md`. + +### Added +- FastAPI backend (`backend/app`) with 47-table PostgreSQL schema, Alembic migrations, Row-Level Security on 42 tenant tables, append-only audit trigger, per-dimension pgvector HNSW indexes. +- Authentication: registration, login, rotating refresh tokens with reuse detection, lockout, email verification, password reset, TOTP MFA, sessions, invitations, multi-organisation membership and switching, deactivation/suspension. +- RBAC engine: permission catalogue, predefined + custom roles, workspace-scoped and expiring assignments, resource grants with deny-wins and expiry, restricted documents, table-scoped database grants, platform support-access windows. +- Ingestion of 30+ formats with locators, safety checks (magic bytes, secrets/executables, zip bombs, XXE), OCR hook, normalisation, language detection, auto-tags, prompt-injection screening, versioning, duplicate detection, background jobs with progress. +- RAG engine: 9 chunking strategies, 10 embedding provider kinds, dense + BM25 + hybrid retrieval, reranking, MMR, PRF expansion, multi-query, parent-child, compression, conversational rewriting, structured (SQL) evidence, grounding with citation verification, refusals, extractive fallback. +- Chat API with SSE streaming, conversations, regenerate, stop, feedback, sharing, export, citation previews re-authorized at view time. +- Database connectors (PostgreSQL, SQLite tested; MySQL/MariaDB/SQL Server/Oracle/Redshift/Supabase/RDS/MongoDB beta), schema discovery, selection with sensitive columns and row filters, full/incremental/scheduled sync with deletion propagation, health history. +- Text-to-SQL with sqlglot validation/rewriting, approvals, query logs; DuckDB sandbox for datasets. +- Integrations: website crawler (robots.txt, SSRF-checked redirects), sitemap, RSS/Atom, GitHub, S3 (beta); catalogue of planned OAuth connectors. +- Connections graph, health and data-flow endpoints; organisation event stream (SSE) with permission filtering; webhooks with HMAC signatures. +- Agents with a provider-agnostic JSON tool loop (KB search, SQL, document retrieval, summarise, extract, chart) and approval-gated tools. +- API keys, analytics, notifications, global search, plan limits, platform administration, onboarding with a sample knowledge base, demo seed and bootstrap-admin scripts. +- Next.js 15 frontend with design system, permission-aware navigation, all 17 sections, streaming chat with citations, and the animated Connections command center. +- PostgreSQL-backed job queue (SKIP LOCKED, LISTEN/NOTIFY, retries, dead-letter, stale-lease recovery, advisory-locked scheduler). +- Docker images (non-root), Compose stack (pgvector, Redis, MinIO, migrations, worker, Caddy TLS), backup/restore scripts. +- Backend tests on real PostgreSQL + pgvector; RAG evaluation harness and results. + +### Changed +- LLM provider abstraction (from v2) kept and extended to OpenAI, Azure OpenAI, Anthropic, Gemini, Bedrock, Ollama, vLLM, OpenAI-compatible, Hugging Face and custom endpoints over `httpx`, with retries, usage accounting, health checks and fallbacks. +- CSV loader/profiler/sampler and Chat/Summary/Analysis services retained as the dataset analysis engine. + +### Removed +- Streamlit UI, `streamlit_app.py`, Streamlit Docker files and `push-to-github.ps1` (which force-pushed after deleting `.git`).

Organisations see which model that is under Settings → AI providers. +* **Billing** — `BILLING_ENABLED=false` (default) gives every organisation the unlimited plan. +* **SaaS integrations** — `OAUTH__CLIENT_ID` / `_CLIENT_SECRET` per vendor and `OAUTH_MICROSOFT_TENANT`; see below. `ALLOW_PRIVATE_WEB_INGESTION` / `SSRF_ALLOWLIST` also govern self-managed GitLab, Confluence site URLs and IMAP hosts. + +### OAuth apps for SaaS integrations + +Google Drive, OneDrive, SharePoint, Dropbox and Microsoft Teams connect only through OAuth. Notion, Confluence Cloud and Slack can use OAuth or a token (internal integration token; email + API token; `xoxb-` bot token). GitLab and email (IMAP) use a token or password and need no app. An operator registers each OAuth app **once per deployment**; every organisation then authorizes its own account with **Connect with …** in Integrations. Until a vendor's variables are set, its card shows **Needs setup** (admins see the variable names and the redirect URI) and the flow cannot start. + +**Redirect URI** — register exactly `{PUBLIC_APP_URL}/api/v1/integrations/oauth/callback` with every vendor, e.g. `https://rag.example.com/api/v1/integrations/oauth/callback` (locally `http://localhost:3000/api/v1/integrations/oauth/callback`; the web app proxies `/api/*` to the API). Set the variables on **both `api` and `worker`** (the worker refreshes tokens during scheduled syncs) and restart them. Tokens are stored encrypted with `ENCRYPTION_KEYS`. + +| Vendor (integrations) | Variables | Register at | Scopes and settings | +| --- | --- | --- | --- | +| Google (Google Drive) | `OAUTH_GOOGLE_CLIENT_ID`, `OAUTH_GOOGLE_CLIENT_SECRET` | Google Cloud console → APIs & Services: enable the Google Drive API, configure the consent screen, then Credentials → OAuth client ID → *Web application* | `https://www.googleapis.com/auth/drive.readonly`, requested with `access_type=offline&prompt=consent` so a refresh token is issued. It is a restricted scope: apps for external users need Google's verification. Docs/Sheets/Slides are exported as docx/xlsx/pptx. | +| Microsoft identity platform (OneDrive, SharePoint, Teams) | `OAUTH_MICROSOFT_CLIENT_ID`, `OAUTH_MICROSOFT_CLIENT_SECRET`, `OAUTH_MICROSOFT_TENANT` (default `common`) | Microsoft Entra admin center → App registrations → New registration, platform *Web* with the redirect URI; Certificates & secrets → client secret | Delegated Microsoft Graph permissions `offline_access`, `User.Read`, plus `Files.Read.All` (OneDrive), `Sites.Read.All` (SharePoint), `Team.ReadBasic.All`, `Channel.ReadBasic.All`, `ChannelMessage.Read.All` (Teams; needs admin consent). Use a directory id or domain as the tenant for a single-tenant app; an integration can override it (`tenant`). | +| Dropbox (Dropbox) | `OAUTH_DROPBOX_CLIENT_ID` (App key), `OAUTH_DROPBOX_CLIENT_SECRET` (App secret) | Dropbox App Console → Create app → *Scoped access*, *Full Dropbox*; add the redirect URI | Permissions `account_info.read`, `files.metadata.read`, `files.content.read`; `token_access_type=offline` for a refresh token. | +| Notion (Notion) | `OAUTH_NOTION_CLIENT_ID`, `OAUTH_NOTION_CLIENT_SECRET` | notion.so/my-integrations → New integration → *Public*, with the redirect URI | *Read content* capability. The token exchange uses HTTP Basic with the client id/secret. Only pages the user shares during consent are synced. | +| Atlassian (Confluence Cloud) | `OAUTH_ATLASSIAN_CLIENT_ID`, `OAUTH_ATLASSIAN_CLIENT_SECRET` | developer.atlassian.com → Developer console → Create → *OAuth 2.0 integration*; Authorization → callback URL; Permissions → Confluence API | Granular scopes `read:page:confluence`, `read:space:confluence`, plus `offline_access`; `audience=api.atlassian.com`. The Confluence site comes from `accessible-resources` (the integration's `site_url` picks one when the account has several); API calls go to `https://api.atlassian.com/ex/confluence/{cloudid}/wiki`. | +| Slack (Slack) | `OAUTH_SLACK_CLIENT_ID`, `OAUTH_SLACK_CLIENT_SECRET` | api.slack.com/apps → Create app → OAuth & Permissions → Redirect URLs | Bot token scopes `channels:read`, `channels:history`, `groups:read`, `groups:history`, `users:read` (`oauth.v2.access`). Invite the bot to every channel it should read. | + +Only GitLab has been checked against the live service (a public gitlab.com project); the other integrations are **beta** — implemented and tested against stubbed vendor APIs. Run **Test** after the first connection for each vendor before relying on scheduled syncs. + +## 4. AI providers and local models + +Configure providers per organisation in **Settings → AI providers**. Credentials are encrypted at rest. Any hosted or self-hosted model can be used: OpenAI, Anthropic, Google Gemini, Azure OpenAI, AWS Bedrock, Ollama, vLLM, Hugging Face TGI, or any OpenAI-compatible server (LM Studio, llama.cpp, LocalAI, gateways such as LiteLLM). Model lists are discovered live from each provider's API (OpenAI-compatible `/v1/models`, Anthropic Models API, Gemini `models.list`, Ollama `/api/tags`), stored as suggestions, and refreshed daily by the worker, so new models appear without a platform release; any model id can also be typed. Azure (deployment names) and Bedrock take typed ids. For a self-hosted Ollama on the Docker network, add a service (e.g. `ollama/ollama`) and configure the provider URL `http://ollama:11434`; for an Ollama on the host, add its hostname to `SSRF_ALLOWLIST`. Ollama prompts are sized automatically (`num_ctx`). + +Embedding models are chosen per knowledge base: `hashing` (built-in, offline, lexical), `local` (ONNX `BAAI/bge-small-en-v1.5` via fastembed — downloaded on first use, ~130 MB), or an API provider. Changing a knowledge base's embedding model schedules a re-index. + +## 5. Operations + +### Health & monitoring +* Liveness `GET /api/v1/health`; readiness `GET /api/v1/health/ready` (DB latency and migration revision, storage, Redis, job counts). Docker health checks use them. +* Logs are structured JSON (`LOG_JSON=true`) with request IDs; every API response carries `X-Request-ID`. Secrets are redacted before logging. +* Platform admins see system health, job queues, dead jobs (with retry), AI provider status and usage in **Administration**. Organisation admins see connection health in **Connections** and usage in **Analytics**. + +### Background jobs +Scale workers horizontally: `docker compose up -d --scale worker=3`. Jobs are claimed with `SKIP LOCKED`; stale leases are recovered by the scheduler. Failed jobs retry with exponential backoff; jobs that exhaust retries are marked `dead` and the creator is notified. + +### Backups +```bash +./deploy/backup.sh # → backups/db-.dump + backups/storage-.tar.gz +``` +Schedule nightly with cron and copy `backups/` off-site. `BACKUP_RETENTION_DAYS` (default 14) prunes old archives. + +### Restore +```bash +./deploy/restore.sh backups/db-.dump +docker compose stop minio && gunzip -c backups/storage-.tar.gz | docker compose run --rm -T --entrypoint tar minio -C /data -xf - && docker compose start minio +``` +Test restores regularly on a staging host. + +### Upgrades +```bash +git pull +docker compose build +./deploy/backup.sh +docker compose up -d # migrate runs first; api/worker start after it succeeds +``` +Migrations are forward-only in production; take a backup before upgrading. Rolling back means restoring the backup and checking out the previous release. + +### Encryption key rotation +1. Prepend a new Fernet key to `ENCRYPTION_KEYS` and restart `api`/`worker` (new secrets use the new key; old ones still decrypt). +2. Re-save credentials (or rotate them) to re-encrypt with the new key, then remove the old key. + +## 6. Production hardening checklist + +- [ ] `ENVIRONMENT=prod`, unique secrets, `COOKIE_SECURE=true`, real SMTP. +- [ ] DNS + TLS working; only ports 80/443 exposed (Postgres, Redis, MinIO stay on the Docker network). +- [ ] `ALLOW_PRIVATE_WEB_INGESTION=false` for multi-tenant SaaS; review `ALLOW_PRIVATE_NETWORK_TARGETS`. +- [ ] Give the platform read-only accounts on customer databases. +- [ ] Nightly backups copied off-site; restore tested. +- [ ] Log shipping/alerting on `level=ERROR` and dead jobs. +- [ ] Bootstrap admin password rotated after first login; MFA enabled for administrators. + +## 7. Cloud / Kubernetes notes + +The images are stateless (state lives in PostgreSQL, Redis and S3), so they map directly to managed services: RDS/Cloud SQL/Azure Database for PostgreSQL with pgvector, ElastiCache/Memorystore, S3/GCS (S3 API)/Azure Blob via an S3 gateway. Run `api` as a Deployment behind an ingress with response buffering disabled for `/api/v1/chat/stream` and `/api/v1/events/stream`; run `worker` as a separate Deployment; run `alembic upgrade head` as a pre-install/pre-upgrade Job.

With CSV-AI, you can effortlessly interact with, summarize, and analyze your CSV files in one convenient place. +**Enterprise RAG & knowledge intelligence platform**: a multi-tenant, permission-aware knowledge platform that grew out of the CSV-AI analysis assistant. Organisations connect documents, spreadsheets, databases and web/code sources; members ask questions and get answers **grounded in sources they are allowed to see, with clickable citations** down to the page, sheet row or database query. -## Features +> Status: functional, tested end-to-end on PostgreSQL 16 + pgvector. See [IMPLEMENTATION_STATUS.md](IMPLEMENTATION_STATUS.md) for exactly what is complete, what is implemented-but-untested, and what is planned. -CSV-AI offers the following key features: +## Highlights -- **Interact:** Easily navigate through your CSV files and interact with the data. -- **Summarize:** Generate descriptive summaries for your CSV data. -- **Analyze:** Perform advanced data analysis on your CSV files, including filtering, sorting, and visualizing the data. +- **Multi-tenant by construction** — PostgreSQL Row-Level Security forced on every tenant table, transaction-scoped tenant context, non-superuser DB role enforced at startup, cross-tenant leakage tests. +- **Fine-grained access control** — 55 permissions, 11 predefined roles + custom roles (escalation-safe), workspace-scoped roles, grants to users/teams/departments/roles/workspaces with **deny-wins** and expiry, restricted documents, table-limited database grants. Enforced inside every retrieval query. +- **Serious RAG** — 30+ file formats with page/section/sheet/row locators, 9 chunking strategies, pgvector dense + real BM25 sparse retrieval over the authorized corpus, RRF fusion, feature reranking, MMR, query expansion, parent-child, compression, conversational query rewriting, prompt-injection screening, citation verification, honest refusals. Works offline (extractive answers) or with 10 LLM provider kinds. +- **Databases & Text-to-SQL** — connector framework (PostgreSQL & SQLite tested; MySQL/MariaDB/SQL Server/Oracle/Redshift/MongoDB beta), schema discovery, table/column selection, sensitive columns, row filters, full/incremental/scheduled sync with deletion propagation, and a sqlglot-based SQL validator with approvals. +- **CSV-AI heritage** — every uploaded CSV/XLSX/JSON/Parquet becomes a dataset with profiling, deterministic analysis, summaries and natural-language/SQL querying (DuckDB sandbox). +- **Connections command center** — a live, animated map of the organisation's data ecosystem built from real resources and real-time events (SSE), plus list and data-flow views. +- **Operations** — PostgreSQL-backed job queue with retries/dead-lettering, webhooks (HMAC-signed), scoped API keys, audit log (append-only), analytics, plan limits, platform administration without tenant content access, Docker Compose with TLS, backups. -## Installation +## Quick start -To run CSV-AI, follow these steps: - -1. Clone this repository to your local machine. -2. Navigate to the project directory. +**Docker (single server):** ```bash -git clone https://github.com/Safiullah-Rahu/CSV-AI.git -cd csv-ai -``` -3. Install the required packages using `pip` with the provided `requirements.txt` file. -```bash -pip install -r requirements.txt +cp .env.example .env # fill in secrets — see DEPLOYMENT.md +docker compose up -d --build ``` -## Usage -To start CSV-AI, run the following command: -```bash -streamlit run app.py +**Local development (no Docker; embedded PostgreSQL):** + +```bash +cd backend && python -m venv .venv && .venv/Scripts/activate && pip install -e ".[dev,local-embeddings]" +python scripts/dev.py # API :8000 +python scripts/seed_demo.py # optional demo data +cd ../frontend && npm install && npm run dev # UI :3000 ``` -This command will launch the CSV-AI app in your default web browser. You can then start exploring and analyzing your CSV files. -CSV-AI App Homepage +To get generated answers in development without configuring a provider in the UI, start the API with a file holding `ANTHROPIC_API_KEY` and/or `OPENAI_API_KEY` (only those keys, plus `ANTHROPIC_WORKSPACE_ID`, are read and never printed): `python scripts/dev.py --env-file ../.env.keys`. Organisations without their own provider then answer with Claude Sonnet 5.5 or GPT-5.4 mini. A local Ollama provider is available too (`seed_demo.py --ollama`), but small models on a CPU are slow and unreliable. + +## Documentation -## Feedback and Contributions -If you have any feedback, suggestions, or issues related to CSV-AI, please open an issue on the GitHub repository.

An admin can only require MFA after enabling it on their own account (`test_org_policy.py`). +* Email verification and password-reset tokens are single-use, hashed, and expire (24 h / 1 h); "forgot password" never reveals whether an account exists. +* API keys: `rk_` prefix + random body, stored as SHA-256, scoped to a subset of the creator's permissions, expiring, revocable, rate-limited, never able to create keys or act as platform admin. + +## Authorization + +See ARCHITECTURE.md → Authorization model. Highlights: deny beats allow (even for admins), expiring grants and role assignments, escalation prevention for custom roles and role assignment, owner protection (last owner cannot be removed or suspended), self-approval blocked for SQL approvals, approved queries execute with the requester's permissions, agents inherit the requesting user's permissions and can only narrow scope. Authorization denials are themselves audited. + +## RAG-specific protections + +| Threat | Control | +| --- | --- | +| Cross-tenant / unauthorized retrieval | Access scope compiled into every dense, sparse, keyword and hybrid query; BM25 statistics computed only over the authorized corpus; citations, previews, shares and exports re-authorized at view time (`test_rag_permissions.py`) | +| Prompt injection in documents / web pages | Injection screening at ingestion (flags chunks and documents), instruction-like spans neutralised before entering the prompt, sources wrapped as untrusted data with explicit system rules, optional quarantine of flagged chunks per KB (`test_prompt_injection_document_is_flagged_and_neutralized`) | +| Fabricated citations | Citations are built from retrieved chunks only; unknown `[S#]` markers are stripped and reported (`test_fabricated_citations_are_stripped`) | +| Unsupported claims | Sentence-level support check; unsupported statements are surfaced in the UI; strict policy appends a verification warning | +| Insufficient evidence | IDF-weighted evidence threshold → refusal without calling the model | +| Data exfiltration via markdown images | Injection patterns include image beacons; the chat renderer does not render raw HTML (react-markdown without rehype-raw) | +| Poisoned / malicious uploads | Extension + magic-byte agreement, executables and secret files (`.env`, keys, keystores) rejected, binary-in-text rejected, zip-bomb ratio/size limits, XML parsed with entity resolution and network disabled (XXE test), size limits enforced while streaming | +| Insecure agent tools | Tools run with the user's permissions; approval-required tools pause the run and create an approval request | + +## Text-to-SQL + +Validator-enforced read-only single statements, forbidden node and function lists (incl. `pg_sleep`, file readers, `dblink`, `set_config`, DuckDB `read_*`/`glob`), allow-listed tables/columns, sensitive/excluded columns removed from the model's schema and from `SELECT *`, admin row filters injected into the query, hard row limits, join limits, approvals, server-side statement timeouts, read-only transactions, DuckDB sandbox with external access disabled. 36 validator tests plus live PostgreSQL/SQLite tests (`test_text2sql_validator.py`, `test_databases.py`). Recommendation: also give the platform a read-only database account. + +## Network egress (SSRF) + +`app/core/netguard.py` resolves every user-supplied destination (database hosts, AI endpoints, webhooks, crawls) and blocks cloud metadata and link-local ranges always, loopback and **the platform's own database endpoint** always, and private ranges by policy (`ALLOW_PRIVATE_NETWORK_TARGETS`, `ALLOW_PRIVATE_WEB_INGESTION`). Web crawls re-validate every redirect hop, honour robots.txt, cap page size, and stay on the start host. SQLite connections are confined to administrator-approved directories and opened read-only. *Residual risk:* DNS rebinding between the check and the connection is not fully prevented for HTTP fetches. + +## Secrets + +* Database passwords, integration tokens, AI provider keys, webhook signing secrets and MFA secrets are encrypted with Fernet (`MultiFernet`, key rotation by appending keys) in the `credentials` table and never returned by the API (tests assert keys never appear in responses or audit logs). +* Logs pass through a redaction filter (passwords, tokens, bearer headers, connection-string credentials, `sk-`/`rk-` keys); connector errors are scrubbed before being stored or returned. +* Production start is refused with default JWT secret, missing encryption keys, insecure cookies or console email. + +## SaaS integrations and OAuth + +* **Authorization code + PKCE (S256)** for every OAuth vendor (Google, Microsoft identity platform, Dropbox, Notion, Atlassian, Slack). A fresh code verifier is generated per start, is never stored in the database, and travels only inside the signed state, **encrypted** with the platform Fernet key. +* **State** is a JWT signed with `JWT_SECRET` (type `oauth_state`, 10-minute expiry) carrying organization, user, integration and vendor. The callback is a browser redirect without a bearer token, so it authenticates through the state alone, then re-checks that the user is still an active member holding `org.integrations` and that the organization is active. +* **Single use without a migration:** starting a flow stores the SHA-256 of a random nonce in `integrations.cursor`; the callback compares it in constant time and clears it *before* contacting the vendor. Replays, older links (a newer start supersedes them) and vendor-side cancellations all consume or fail the state. Every outcome is audited (`integration.oauth_start`, `integration.oauth_connect` with success/failure/denied). +* **Token storage:** access token, refresh token, expiry and non-secret vendor extras (Atlassian cloud id and site, Slack team, Notion workspace) are encrypted JSON in the integration's `credentials` row. The API only ever returns `connected`, an account label and the connection time; tokens and the PKCE verifier never appear in responses, events or audit metadata (asserted in `test_integrations_saas.py`). The log redaction filter also masks Slack (`xox?-`), GitLab (`glpat-`), Notion (`ntn_`) and Google (`ya29.`) token formats and `code_verifier` / `refresh_token` / `access_token` / `client_secret` parameters. A secret cannot be supplied through the API for an OAuth-mode integration, and switching an integration between OAuth and token mode deletes the old credential. +* **OAuth app secrets** are deployment settings (`OAUTH_*_CLIENT_SECRET`), never stored per organization and never sent to the browser; the catalog only lists the *names* of missing variables. Starting a flow for an unconfigured vendor is refused (HTTP 501). +* **Refresh:** an expired access token (or a 401) triggers the refresh-token grant; rotated refresh tokens (Microsoft, Atlassian, Dropbox) are persisted immediately, from inside the sync job when needed. *Residual risk:* two concurrent syncs of one integration can race on a rotating refresh token; the loser fails until the next run or a reconnect. +* **Egress:** vendor APIs are fixed hosts. User-supplied hosts (GitLab `base_url`, Confluence `site_url`, IMAP `host`) pass the SSRF guard under the web-ingestion policy (`ALLOW_PRIVATE_WEB_INGESTION`, `SSRF_ALLOWLIST`). Redirects are followed by hand with every hop re-checked, and the bearer token is dropped whenever a redirect changes host (pre-signed download URLs from Graph). Responses are capped at 10 MB while streaming; `Retry-After` is honoured up to 60 s. IMAP requires SSL/TLS or STARTTLS with certificate verification; plaintext IMAP is refused. +* **Revocation:** deleting an integration deletes its tokens but does not revoke the grant at the vendor. Revoke the app there as well (Google account permissions, Entra enterprise apps, Slack app management, and so on). +* Synced content (emails, chat messages, wiki pages) is untrusted input: it goes through the same ingestion screening (prompt-injection flags, quarantine) as uploads. + +## Web security + +Security headers on API and frontend (CSP, `X-Frame-Options: DENY`, `nosniff`, Referrer-Policy, Permissions-Policy, HSTS in production), strict CORS allow-list, request IDs on every response, standardised error bodies without stack traces, Pydantic validation on every input. + +The frontend CSP allows `img-src https:` so an organisation's branding logo (an admin-configured `https://` URL) can load. The image is requested with `referrerpolicy="no-referrer"`, but the logo host still sees members' IP addresses; organisations that consider this sensitive should host the logo on their own domain. + +## Audit + +Append-only `audit_events` (database trigger rejects UPDATE/DELETE outside system retention) covering authentication, membership, roles, grants, knowledge bases, documents, downloads, connections, credentials rotation, queries, approvals, exports, API keys, webhooks, support access and authorization denials, with actor, IP, user agent, request ID and sanitised metadata. CSV export for administrators. + +## Data lifecycle + +Document deletion removes the row, all versions, chunks, embeddings, dataset Parquet copies and stored objects, and scrubs snippets from past citations. Knowledge-base deletion cascades the same way. Credential deletion on connection removal. Organisation deletion deactivates immediately and a purge job removes every row and object. Integration syncs propagate source deletions; database syncs propagate deleted rows. Retention settings exist per organisation (conversation and audit retention values are stored; automated retention purge jobs are **planned**, see IMPLEMENTATION_STATUS.md). + +## Dependency hygiene + +Pinned frontend dependencies (Next.js 15.5.28, a patched release line); backend dependencies declared with minimum versions in `pyproject.toml`.

That narrow check also + existed in the engine, where it was a real bug: under the strict policy an + uncited "the sources don't contain …" would have been withheld and replaced + with unrelated passages. Refusal detection is now one shared function + (`grounding.is_refusal`, tested in `test_refusal_detection_covers_common_phrasings` + and `test_uncited_refusal_is_not_withheld_in_strict_mode`), and the saved + answers were re-scored offline with it (`refusal_accuracy_unanswerable_rescored` + in each file). No answers were regenerated. +- **GPT-4.1 mini 0.833.** On one unanswerable question (parental leave) its + answer carried no citation and its wording was not recognised as a decline, + so the strict policy withheld it and showed the closest passages instead: a + conservative failure, but not a correct refusal. The harness did not yet + record withheld text; a targeted re-run (`--grep parental`) produced a + recognised decline (*"The provided sources do not contain any information + about the company's parental leave policy."*). The detector now also covers + openings such as "There is no information …" and "None of the sources …", + and the harness records `rejected_model_answer` for future runs. +- **Opus citation correctness 0.933.** In two answers Opus added a second, + correctly cited fact from another document (the one-hour data-loss rule next + to the 24-hour lost-equipment rule; the MFA requirement next to account + creation). The metric only allows the document labelled relevant, so it + counts both as misses. The extra statements are accurate and supported. +- **Effort.** The Claude runs used each model's default effort (Sonnet 5.5: high, + Opus 5.5: medium) because the provider factory did not yet forward the new + `effort` setting. That is fixed; `EVAL_EFFORT` (default `low`) now applies. +- **Latency.** Retrieval latency in these runs (44–187 ms mean) is inflated: + the machine was running several builds and browser sessions at the time. + Use the extractive runs above for retrieval timing. +- **Two live bugs found on the way, both now fixed.** The first Claude + request returned HTTP 400 (`temperature is deprecated for this model`): the + provider still sent sampling parameters on API version `2023-06-01`. It now + uses `2026-10-21`, which rejects them on every model, and no longer sends + them. The first GPT-5.4 mini request returned HTTP 400 (`'max_tokens' is not + supported with this model`): the OpenAI provider now sends + `max_completion_tokens` to OpenAI's own API (compatible servers keep + `max_tokens`) and retries once without `temperature` for models that accept + only the default. In both cases the engine fell back to an extractive answer, + as designed, until the fix landed. + +## Generated answers with a local model: not credibly measured on this machine + +Two runs with a local Ollama `qwen2.5:7b-instruct` (10 questions each, +`20261102-024233-…` and `20261102-025249-…`) scored 0 on answer relevance, +citations and faithfulness, with empty answers recorded. The log +(`llm_run.log`) shows why: Ollama repeatedly aborted generation with +`prediction aborted, token repeat limit reached`, meaning the model fell into +repetition loops. In manual checks on the same machine it also produced garbled +text for trivial prompts. Inference was CPU-only (30–49 s per attempt). These +runs therefore measure a malfunctioning local model, not the RAG pipeline, and +they are reported only for completeness. + +They also exposed a boundary in the engine's fallback: if a model fails +**before** emitting any text, the engine answers extractively with a notice +(`test_model_failure_before_output_falls_back_to_extractive`); if it fails +**mid-answer**, as here, the request ends with an error event and the partial +answer is kept. Uncited model answers under the strict policy are withheld and +replaced by an extractive answer +(`test_uncited_model_answer_is_withheld_in_strict_mode`).

Two workers, +no retries locally (one on CI), trace and screenshot kept on failure in +`frontend/test-results/`, HTML report in `frontend/playwright-report/` (both git-ignored). + +### Configuration + +| Variable | Default | Purpose | +|---|---|---| +| `E2E_BASE_URL` | `http://localhost:3000` | Where the browser opens the app | +| `E2E_API_URL` | `E2E_BASE_URL` | Origin used to seed data through `/api/v1` | +| `E2E_BACKEND_LOG` | unset | File with the backend's stderr; invitation links are read from it | +| `E2E_BACKEND_PYTHON` | `backend/.venv` Python, else `python` | Interpreter for `e2e/support/set_invite_token.py` | +| `E2E_BACKEND_DIR` | `/backend` | Backend checkout (to find its `.venv`) | +| `DEVDB_DIR` / `E2E_DEVDB_NAME` | `backend/var/pgdata` / `rag` | Embedded dev database used by the token helper | + +### Test data and rate limits + +- `e2e/global-setup.ts` checks `GET /api/v1/health`, then signs in an owner account and + creates a fresh organization `e2e-run-` for the run. Every name starts with `e2e-` + and every email ends in `@example.com`. Data is left in place after the run. +- Registration is limited to `REGISTER_RATE_LIMIT_PER_HOUR` (default 10 per IP per hour, + in memory). The owner is registered once and cached in `frontend/e2e/.state/owner.json` + for later local runs, so a run registers one account (the sign-up test), or two on the + first run. Invited members are created by accepting invitations, which is not rate limited. + Delete `e2e/.state/` to start over with a new owner. +- Login is limited to 10/min per email and 30/min per IP. Each browser context signs in on + its own (refresh tokens rotate on every refresh, and replaying one from another context + revokes the whole session family), so a busy run can reach the per-email limit; the + helpers wait out the window and retry. To run the suite many times in a row, start the + backend with higher limits, for example + `REGISTER_RATE_LIMIT_PER_HOUR=1000 LOGIN_RATE_LIMIT_PER_MINUTE=1000 python scripts/dev.py`. + The limiter is in memory, so restarting the backend also resets it. +- Browsers are signed in either through the login form or with `page.request` (which shares + the context's cookies), so the app boots from its httpOnly refresh cookie as it does after + a real sign-in. Seeding uses an access token through the API. + +### Invitation links + +Invitations are only delivered by email. With the dev `console` email backend the backend +prints `[dev email] … -> : http://…/invite?token=…` to its stderr. + +- If `E2E_BACKEND_LOG` points at that output, the tests read the real token from it (CI + does this). +- Otherwise, for example against a dev server whose output is not in a file, the test picks + a token and `e2e/support/set_invite_token.py` stores its SHA-256 hash on that one pending + invitation in the embedded dev database. The invitation is then accepted through the + normal API or `/invite` page. This helper is for local dev databases only. + +### Chat and model cost + +The chat test asks one question per run. If the backend has a language model (the dev +backend falls back to the platform's Claude key when started with `--env-file`), that is one +real, paid model call; without a model the answer is extractive. The test only asserts the +fact from the fixture, a citation chip and the source panel, so it passes either way. + +### Scenarios + +| Spec | Covers | +|---|---| +| `auth.spec.ts` | Register, create the first organization, Overview renders, sign out, sign in again | +| `knowledge.spec.ts` | Create a knowledge base, upload a Markdown file, wait until indexed, document row and chunk count | +| `chat.spec.ts` | Ask about the fixture, answer has the fact and a citation chip, the Sources panel opens | +| `access-control.spec.ts` | Invite a member through the API and accept; the member signs in, admin-only navigation is hidden, `/admin` shows the 403 screen, a restricted knowledge base is absent (also by direct link) | +| `security-policy.spec.ts` | In a separate organization, an owner turns on two-factor (TOTP computed with Node `crypto`, RFC 6238) and requires it; a member joining through `/invite` sees "Two-factor authentication required" | +| `connections.spec.ts` | The Connections map renders nodes; the List view works | +| `shell.spec.ts` | Theme toggle persists across reload; Ctrl+K command palette navigates; owner sees admin navigation | +| `mobile.spec.ts` | 390 px: the navigation drawer opens and navigates; key pages have no horizontal overflow | + +Known issue: `mobile.spec.ts` › "the overview has no horizontal overflow at 390 px" is +marked `test.fixme`. The Overview's analytics chart props its grid column open at phone +width, so the content panel scrolls sideways. Remove `.fixme` once that is fixed. + +### Continuous integration + +The `e2e` job in `.github/workflows/ci.yml` sets up Python 3.12 and Node 20, installs the +backend (`pip install -e ".[dev]"`), starts `python scripts/dev.py` in the background with +its output in `e2e-logs/backend.log` (embedded PostgreSQL via pgserver), waits for +`/api/v1/health`, builds the frontend and starts the standalone server, installs Chromium +with `npx playwright install --with-deps chromium`, and runs `npm run test:e2e`. It raises +`REGISTER_RATE_LIMIT_PER_HOUR` and `LOGIN_RATE_LIMIT_PER_MINUTE`, reads invitation links +from the backend log, and uploads the HTML report, traces and server logs when it fails. +No model keys are configured there, so chat answers are extractive. + +The job has not been run yet: it was written without access to a GitHub runner. One thing +to check on the first run: on Linux, pgserver serves PostgreSQL on a Unix socket +(`postgresql://postgres:@/postgres?host=`), while `backend/scripts/devdb.py` builds its +connection URLs by splitting a TCP-style URI. If `scripts/dev.py` fails to connect there, +that helper is the cause, and it affects the backend test job too. diff --git a/frontend/.dockerignore b/frontend/.dockerignore new file mode 100644 index 0000000..b90a368 --- /dev/null +++ b/frontend/.dockerignore @@ -0,0 +1,2 @@ +node_modules +.next diff --git a/frontend/.gitignore b/frontend/.gitignore new file mode 100644 index 0000000..eb1786e --- /dev/null +++ b/frontend/.gitignore @@ -0,0 +1,5 @@ +node_modules +.next +out +*.tsbuildinfo +.env*.local diff --git a/frontend/Dockerfile b/frontend/Dockerfile new file mode 100644 index 0000000..c8ba2c5 --- /dev/null +++ b/frontend/Dockerfile @@ -0,0 +1,27 @@ +# syntax=docker/dockerfile:1.7 +FROM node:22-alpine AS deps +WORKDIR /app +COPY package.json package-lock.json ./ +RUN npm ci --no-audit --no-fund + +FROM node:22-alpine AS build +WORKDIR /app +ENV NEXT_TELEMETRY_DISABLED=1 +COPY --from=deps /app/node_modules ./node_modules +COPY . . +# The API is proxied by Next.js rewrites;
