 The aim is to collect traces via OpenTelemetry across all Flux related objects, such as HelmReleases, Kustomizations and among others. These may be sent towards a tracing provider where are going to be stored and visualized. Thereby, this may involve a new API definition obj called `Trace`, which may be capable of linking all the `EventSources` and send them out to a reusable tracing `Provider`. In this way, it could facilitate the observability and monitoring of Flux related objects.
 
 ## Motivation
-This RFC was born out of a need for end-to-end visibility into Flux’s multi-controller GitOps workflow. At the time Flux was one monolithic controller; it has since split into several specialized controllers (source-, kustomize-, helm-, notification-, etc.), which makes tracing the path of a single “Git change → applied resource → notification” much harder.

+Correlate a Git commit with all downstream actions. You want one single trace that (via multiple spans) shows:
-- The Source Controller pulling and applying the new YAML.
+- Source-controller current revision ID.
 - Any Kustomize or Helm reconciliations that ran.

 On top of this, can be built custom UIs that surface trace timelines alongside Git commit or Docker image tags, so operators can say “what exactly happened when I tagged v1.2.3?” in a single pane of glass.

 ### Goals
 - **End-to-end GitOps traceability:** Capture the traces that follows a Git change through all Flux controllers for simply debugging and root-cause analysis.
 - **Declarative, CRD-drive configuration:** Reuse the concept of `Provider` and a similar definition as `Alerts` to build a new API/CR called `Trace`. Therefore, users can link `EventSources` and `Provider` where trace will be sent. Additionally, other setting can be set as sampling rates.
-- **Notification Controller as the trace-collector:** Leverage the notification-controller's existing event watching pipeline to ingest reconciliation events and turn me into OpenTelemetry spans, being forwarwed to an OLTP-compatible backend - `Provider`.

-- **Cross-controller span correlation:** Ensure spans are emitted from multiple, stateless controller can be stiched together into a single trace by using Flux "revision" annotation (GitRepository sync to a downstream Kustomization/HelmRelease reconciliations).

 ### Non-Goals
 - **Not a full-tracing backend:** We won't build or bundle a storage/visualization system. Users may have to still rely on a external collector for long-term retention, querying and UI.
