 ## Gateway

 `nanobot gateway` starts enabled chat channels, WebUI/WebSocket when configured, cron-backed system jobs, Dream, heartbeat, and the health endpoint. Most local browser users should start with `nanobot webui`; use `gateway` directly for service management, chat app operation, and advanced deployment. By default it runs in the foreground, which keeps existing scripts and terminal workflows unchanged. Use `--background` when you want a local macOS, Linux, or Windows process that you can manage from the CLI.

+### Cloudflare Tunnel + Cloudflare Access
+
+For a local `cloudflared` process in front of nanobot, Cloudflare Access can
+authenticate the user before forwarding the request and add
+`Cf-Access-Jwt-Assertion`. Opt in to trusted-proxy no-token mode only when the
+direct TCP peer is the tunnel process and the assertion is non-empty:
+
+```json
+{
+  "gateway": { "host": "127.0.0.1" },
+  "channels": {
+    "websocket": {
+      "host": "127.0.0.1",
+      "port": 8765,
+      "publicWsUrl": "wss://nanobot.example.com/",
+      "trustedProxyAuth": {
+        "trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
+        "assertionHeader": "Cf-Access-Jwt-Assertion"
+      }
+    }
+  }
+}
+```
+
+This is two-part authorization: a trusted direct loopback peer **and** a
+non-empty Cloudflare Access assertion. A trusted CIDR alone is not a bypass.
+For this flow `/webui/bootstrap` returns connection metadata without a
+bootstrap token or REST API token; the proxy assertion authorizes the WebSocket
+handshake and REST requests directly.
+
+Set `publicWsUrl` to the browser-facing `wss://` endpoint when the tunnel sends
+the origin host header (such as `127.0.0.1:8765`); otherwise the WebUI could
+attempt to open its WebSocket directly against the loopback address.
+The assertion header must be generated
+by Cloudflare Access after authentication; routing/client metadata headers such
+as `Host`, `Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP`
+are rejected as `assertionHeader` values. Nanobot trusts the assertion but does
+not cryptographically validate the JWT, so configure the tunnel and Access
+policy carefully and do not expose the nanobot listener directly to untrusted
+clients. Forwarded client headers do not establish proxy trust.

+The embedded WebUI's `/webui/bootstrap` route returns a WebSocket token and
+REST `api_token` for local or secret-authenticated requests. When
+`trustedProxyAuth` authenticates the direct proxy peer, it returns connection
+metadata only: no bootstrap token, no REST API token, and no token query
+parameter is required for the WebSocket handshake or subsequent REST requests.
+
+### Trusted proxy no-token bootstrap
+
+`trustedProxyAuth` is an opt-in alternative for deployments where an
+identity-aware reverse proxy authenticates the user before connecting to nanobot.
+The proxy assertion becomes the authentication boundary for the entire WebUI
+surface: `/webui/bootstrap`, the WebSocket handshake, and REST API routes.
+Bootstrap is accepted only when **both** the direct TCP peer matches one of
+`trustedPeerCidrs` and the configured assertion header is present and non-empty.
+A trusted address by itself is never sufficient.
+
+Nanobot deliberately uses only `connection.remote_address` for the peer check.
+It never uses `X-Forwarded-For`, `Forwarded`, `X-Real-IP`, `CF-Connecting-IP`,
+or `X-Forwarded-Host` to decide whether the proxy is trusted. Nanobot trusts the
+assertion supplied by the explicitly trusted peer, but does not cryptographically
+validate or interpret the JWT/assertion contents. Do not enable this option if
+untrusted clients can connect directly to the nanobot listener.
+
+The configured assertion header must be a proxy-generated authentication
+assertion, not a routing or client metadata header. Headers such as `Host`,
+`Forwarded`, `X-Forwarded-*`, `X-Real-IP`, and `CF-Connecting-IP` are rejected
+by configuration; use the identity provider's post-authentication assertion
+header instead (for example, `Cf-Access-Jwt-Assertion`).
+
+For example, a local Cloudflare Tunnel with Cloudflare Access can validate the
+user at the edge and forward the resulting `Cf-Access-Jwt-Assertion`:
+
+```json
+{
+  "channels": {
+    "websocket": {
+      "host": "127.0.0.1",
+      "publicWsUrl": "wss://nanobot.example.com/",
+      "trustedProxyAuth": {
+        "trustedPeerCidrs": ["127.0.0.1/32", "::1/128"],
+        "assertionHeader": "Cf-Access-Jwt-Assertion"
+      }
+    }
+  }
+}
+```
+
+This works only when the directly connected `cloudflared` process reaches
+nanobot over the configured loopback address and supplies a non-empty assertion.
+Keep nanobot firewalled from untrusted clients; this configuration is not a
+CIDR-based bootstrap bypass.

-### 2. Enable the WebSocket channel

+
+From the repository root:
+
+```bash
+nanobot webui --dev
+```
+
+The command safely prepares the local WebSocket channel, starts both the gateway and Vite,
+and opens `http://127.0.0.1:5173`. Vite proxies to the configured WebSocket channel and applies
+frontend changes with HMR. Press Ctrl+C in that terminal to stop both processes.
+
+Use `--no-open` to skip opening a browser. `--dev` is foreground-only and cannot be combined
+with `--background`.

chengyongruandchengyongru	44b7e1bf41	fix(providers): keep serde errors explicit	2026-08-03 18:06:45 +08:00
arcdrake22andchengyongru	6eda67b50c	fix(providers): keep reasoning items wire-valid for DeepSeek Responses convert_messages() emitted reasoning items with ``content`` as a plain string whenever preserve_reasoning was enabled (the DeepSeek spec). DeepSeek's Responses gateway rejects that shape with a serde error ("input: invalid type: string ..., expected a sequence"), which surfaced only after token consolidation cleared provider_state and forced the full-history conversion path; replayed server items already carry list content, which is why normal multi-turn requests never failed. Serialize reasoning content as a list of output_text parts, matching the OpenAI Responses schema and DeepSeek's accepted wire shape (verified live against api.deepseek.com/responses). The serde fallback classifier introduced in the previous commit remains as a last-resort safeguard for any remaining wire incompatibility. Tests: extend test_preserves_deepseek_reasoning_content to the array shape; add a full-history regression with the observed failing item, a replay/consolidation regression covering both replayed and converted reasoning items, and provider-level request fixtures for both paths. Full suite: 5773 passed, 22 skipped (only the known local-only channels/sms packaging failure remains).	2026-08-03 18:06:45 +08:00
arcdrake22andchengyongru	fb2688fd37	fix(providers): fall back to chat completions on serde body rejections DeepSeek's new Responses endpoint (deepseek-v4-flash) intermittently rejects valid request bodies with serde deserialization errors such as 'input: invalid type: string ..., expected a sequence'. These were not classified as compatibility errors, so affected conversations died instead of falling back to Chat Completions. The wire format is correct (input serializes as a list), so this is a server-side Responses compatibility issue; Chat Completions is strictly more permissive, making fallback safe. Extend the fallback classifier to recognize serde body-parsing markers. Repeated failures still trip the existing circuit breaker.	2026-08-03 18:06:45 +08:00

Victor M. SMITHandXubin Ren	f42a44817a	feat(providers): add Eden AI as an OpenAI-compatible gateway provider Eden AI (https://www.edenai.co) is an EU-hosted, OpenAI-compatible gateway exposing 100+ models from many providers through a single endpoint and API key. Models use the provider/model naming scheme (the full id is sent upstream, like OpenRouter). Adds it following the registry's documented two-step recipe: - a ProviderSpec in providers/registry.py (backend openai_compat, gateway, default_api_base https://api.edenai.run/v3, EDENAI_API_KEY, reasoning_effort) - the matching field in ProvidersConfig (config/schema.py) API key via EDENAI_API_KEY only; never hardcoded.

arcdrake22andXubin Ren	c6bd5f0075	test(gateway): align runtime-tasks gather tests with bounded retrieval The helper never waits on the runtime-tasks gather after cancelling it (its children are bounded individually), so the finished-gather test must hand the helper an already-complete gather to exercise the bounded retrieval path, and the cancelled-gather test must settle the gather itself instead of expecting the helper to await a still-pending future. Use a pre-completed child for the finished case and suppress(await) for the cancelled case; both now assert done() and a single close.	2026-08-03 16:00:39 +08:00

arcdrake22andXubin Ren	a91ce900ef	test(gateway): add shutdown teardown regression coverage Covers the lifecycle contract of _close_gateway_runtime: runtime tasks are cancelled before shared resources close, pending background work is drained before the close returns, cancellation-swallowing tasks and hanging cleanup are bounded by their timeouts, a failing close is logged without blocking the stop, duplicate cleanup is idempotent, and the runtime_tasks gather await path is exercised for both completed and cancelled gathers.	2026-08-03 16:00:39 +08:00
arcdrake22andXubin Ren	8942c22d86	fix(gateway): close agent resources deterministically on shutdown The gateway shutdown path never closed agent resources explicitly: it relied on the agent loop task's own finally to run close_mcp() when that task is cancelled. When the service stops with an in-flight exec session or MCP subprocess, that path can be skipped or cut short, leaving asyncio subprocess transports alive after the event loop closes. They are then finalized by __del__ against a closed loop, producing "RuntimeError: Event loop is closed" noise in the shutdown log, and in the worst case orphaned subprocesses with the stop stalling until systemd's timeout kills the cgroup. The teardown is now extracted into _close_gateway_runtime() with explicit ordering and bounds: - Runtime tasks (including the agent loop and any in-flight turn) are cancelled and awaited -- bounded -- before exec sessions, subagents, and MCP servers are closed, so no active turn is using a shared resource when it closes. - Channel transports are closed before waiting for their runners to exit, since some SDKs swallow task cancellation while attempting to reconnect. - agent.close_mcp() is invoked explicitly, bounded to 15s, and is idempotent: it is a no-op when the agent loop's own cleanup already ran, and the guaranteed final close otherwise. - A coroutine that swallows cancellation (e.g. an SDK reconnect loop) can no longer hold the stop open until systemd's timeout kills the cgroup; cleanup failures are logged instead of blocking shutdown.	2026-08-03 16:00:39 +08:00

yang1 chengyongru amkile	f7a6bc2d21	fix(webui): globally register correct MIME types for static assets (#5190 ) On Windows, mimetypes.guess_type() reads the Content Type value from HKEY_CLASSES_ROOT\.js (and other extensions) in the registry, which is commonly set to text/plain because .js is associated with Windows Script Host rather than web JavaScript. The registry value overrides Python's built-in mapping and causes browsers to reject ES module scripts. Fix by explicitly registering correct MIME types via mimetypes.add_type() at module import time for common web static extensions (.js, .mjs, .css, .html, .json, .svg, .wasm). Using strict=True ensures the values replace the registry-backed standard mappings used by mimetypes.guess_type(). This benefits all callers of mimetypes.guess_type() in the gateway process, not just _serve_static. Closes #5190 Co-authored-by: amkile <44280409+amkile@users.noreply.github.com>	2026-08-03 11:33:02 +08:00
arcdrake22andchengyongru	08fe9f7b3a	fix(image): send Gemini Flash hints via generationConfig.imageConfig The live v1beta API rejects the legacy responseFormat.image block (enum-based aspectRatio/imageSize fields) for gemini-3.1-flash-lite-image with INVALID_ARGUMENT, even for documented plain-string values. Gemini Flash image models accept plain-string hints under generationConfig.imageConfig instead (e.g. aspectRatio 16:9, imageSize 1K), which the API accepts. Switch the flash path to imageConfig and update the provider tests accordingly. Other providers (aihubmix, ollama, imagen) are untouched.	2026-08-03 11:22:09 +08:00

NearlCrews Xubin Ren Claude Opus 4.7	5eb818e800	fix(providers): require api_base before local provider wins on keyword match Ollama's spec keeps "nemotron" as a keyword so bare `nemotron-3-nano` auto-routes to a configured Ollama install (PR #1863). NVIDIA NIM was later registered with the same "nemotron" keyword (commit `046d0831`), creating the only keyword collision in the registry. In `_match_provider`, the keyword loop accepted any local provider on `spec.is_local` alone — no api_base check. Models like `nvidia/nemotron-3-super-120b-a12b` (intended for OpenRouter or NVIDIA NIM) were therefore hijacked to http://localhost:11434/v1 even when the user had never configured Ollama, causing silent connection errors at runtime. Add the same api_base gate the local-fallback loop already uses: a local provider only wins by keyword when the user has actually set its api_base. Preserves PR #1863's intent for users who configured Ollama; fixes the silent hijack for everyone else. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-08-01 20:25:58 +08:00

KDBandXubin Ren	39bb20c76b	fix(session): tolerate malformed persisted session summary AutoCompact.prepare_session runs on the turn hot path (AgentLoop._compact_session) and read the persisted _last_summary metadata with an unguarded meta['text'] and datetime.fromisoformat(meta['last_active']). A _last_summary dict that was hand-edited or written by another version (missing text/last_active, or a non-ISO last_active) raised KeyError/ValueError out of the turn. Sibling readers already tolerate the same data: estimate_session_prompt_tokens uses .get('text') and _archive parses inside try/except. Mirror that tolerance: skip when text is unusable, and fall back to the session's own updated_at (the value the writer persists) when last_active is missing or unparseable, so the archived summary is preserved instead of crashing the turn.	2026-08-01 19:29:16 +08:00
