+# CozeLoop production integration
+
+Nivora integrates CozeLoop through the official Eino callback adapter and the official CozeLoop Go SDK. The integration is optional and fail-open for customer traffic: tracing or PromptHub outages must not make customer conversations fail.
+
+## Enable tracing
+
+```env
+NIVORA_COZELOOP_ENABLED=true
+COZELOOP_WORKSPACE_ID=your-workspace-id
+```
+
+For local development, an API token can be used:
+
+```env
+COZELOOP_API_TOKEN=your-api-token
+```
+
+Production deployments should use JWT OAuth credentials instead of a long-lived PAT:
+
+```env
+COZELOOP_JWT_OAUTH_CLIENT_ID=your-client-id
+COZELOOP_JWT_OAUTH_PRIVATE_KEY=your-private-key
+COZELOOP_JWT_OAUTH_PUBLIC_KEY_ID=your-public-key-id
+```
+
+## Trace redaction
+
+The Eino callback parser uses an allowlist. It may export:
+
+- model provider and endpoint/model name
+- input, output, and total token counts
+- first-response latency
+- stream flag
+- Prompt key, version, and provider
+- Tool call ID
+
+It deliberately removes:
+
+- customer questions and conversation history
+- model answers and reasoning content
+- Tool inputs and Tool outputs
+- bearer contexts and service secrets
+- raw Provider payloads
+- product-internal prompts, recipes, and hidden metadata
+
+The root Nivora run span contains only support-safe identifiers and release metadata: request ID, conversation ID, tenant ID, Nivora version/commit, active Prompt version/source, authentication state, scope count, and Tool count.
+
+## Approved Prompt policy
+
+Nivora's mandatory safety rules are compiled into the binary. CozeLoop PromptHub may provide only an additional approved system-policy appendix.
+
+```env
+NIVORA_COZELOOP_PROMPT_KEY=nivora.support.policy
+NIVORA_COZELOOP_PROMPT_VERSION=v1.2.0
+NIVORA_COZELOOP_PROMPT_REFRESH=5m
+NIVORA_COZELOOP_PROMPT_TIMEOUT=3s
+```
+
+Production should pin an approved Prompt version. An empty version means "latest" and should be limited to controlled staging.
+
+A remote Prompt is accepted only when it contains at least one non-empty system-role message and the combined appendix is at most 32 KiB. User-role-only Prompts are rejected.
+
+Failure behavior:
+
+1. Keep the most recent successfully fetched Prompt in memory.
+2. If no remote Prompt has ever succeeded, use the bundled policy.
+3. Never stop serving because PromptHub is unavailable.
+4. Never allow a remote appendix to weaken the compiled safety rules.
+
+## Diagnostics
+
+`GET /version` reports:
+
+- Nivora version and commit
+- configured Prompt key
+- active Prompt version and source
+- whether CozeLoop initialized successfully
+
+No credential or raw Prompt content is returned.
