Make Secret injection conditional.
Line 22 describes the Secret as optional. Line 23 then says Helm injects both resources. When neither headers nor an existing Secret is configured, only the ConfigMap exists. Change “both” to “the ConfigMap and, when configured, the Secret.”

| If your backend requires an ingestion key, you have two options. | ||

Keep real ingestion keys out of shell arguments.
If an operator replaces the placeholder, shell history records the key and process inspection can expose it while Helm runs. Prefer the External Secrets flow below or a protected, uncommitted values/secret-file mechanism. State explicitly that real credentials must not be supplied with --set or committed to a values file.
Proposed wording
-```bash
---set observability.otel.headers='x-api-key=your_ingestion_key'
-```
+Use the External Secrets flow below, or pass this value through a protected, uncommitted values/secret-file mechanism. Do not place a real key in a shell argument.🤖 Prompt for AI Agents

Document CORS preflight requirements for frontend.headers.
The default x-otlp-browser=1 is a custom request header. Browser export can therefore send a preflight request. The receiver must allow the Plane origin, handle OPTIONS, and allow the configured request headers and POST. The current instruction only mentions the origin, so browser telemetry can remain empty despite an otherwise correct setup.
Proposed wording
-- The receiver must allow cross-origin requests (CORS) from your Plane domain.
+- The receiver must allow CORS from your Plane domain, handle `OPTIONS` preflight requests, and allow `POST` plus every configured exporter request header, including `x-otlp-browser` when the default is used.📝 Committable suggestion

| 3. Generate some traffic in Plane and look for spans from `api` in your backend. Traces from a single request should span the API, Celery workers, and database calls. | ||
|
|
||
| If nothing arrives, check that the endpoint is reachable from a pod in the Plane namespace, and that the protocol matches the receiver port — gRPC receivers usually listen on `4317` and HTTP receivers on `4318`. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Make span verification conditional on request behavior.
A request that does not enqueue a Celery task cannot produce a worker span. A request that does not access the database cannot produce a database span. Require those spans only when the generated traffic exercises those components.

- Traces from a single request should span the API, Celery workers, and database calls.
