Implement the distributor v0.5 PipelineID update

 The upstream application needs these values from deployment or operator configuration:
 
 - distributor endpoint: the HTTP server base URL, such as `https://distributor.example.com`;
-- upload token: bearer token for exactly one configured `http_upload` pipeline;
+- upload token: bearer token that authenticates the producer;
+- pipeline id: configured `http_upload` pipeline that should process this upload;
 - generated files: regular local files to include in the source bundle;
-- bundle id: stable identifier for this producer output;
-- idempotency key: stable key for retrying the same producer operation.
+- bundle id: stable identifier for the logical report stream or artifact;
+- idempotency key: unique key for one producer run, reused only when retrying that same run.
 
 Do not put destination routing, public URLs, transform settings, or credentials in the source manifest. Those belong in the `distributor` pipeline configuration.
 
+The token, pipeline id, bundle id, and idempotency key have different jobs. The token authenticates the producer. The pipeline id selects the configured distributor workflow, including destinations and publishing policy. The bundle id tells `distributor` whether a new upload is a newer version of the same source; keep it stable across runs that should replace the same managed destination artifact. The idempotency key tells `distributor` whether an upload request is a retry; change it for each distinct producer run so new content is enqueued.

 ## Recommended Workflow

+- Use a stable bundle id for the logical producer output that should replace the same destination artifact, such as `weather.hourly.brentwood`.

+- Do not include per-run timestamps, random values, or job ids in the bundle id unless each run should be treated as a different source.
+- Use an idempotency key that changes for every distinct producer run, such as `<bundle-id>.<run-id>`.
+- Reuse the same idempotency key only when retrying the exact same producer run with the same source manifest.
 - Map each generated file to a clean slash-separated bundle path, such as `report.md` or `assets/chart.png`.
 - Include only regular files. Symlinks, directories as files, devices, FIFOs, and sockets are rejected.
 - Keep file contents stable after upload inputs are selected. Bundle digests are calculated from file bytes.

 ## Idempotency And Status

-For producer jobs that may retry after process restart, supply a stable key derived from the producer operation, such as the report id or job id. Reusing the same key with the same normalized source manifest returns the original accepted run. Reusing the same key with different source content returns a conflict.
+For producer jobs that may retry after process restart, supply a key derived from the producer run, such as `<bundle-id>.<run-id>`. Reusing the same key with the same token, pipeline id, and normalized source manifest returns the original accepted run. Reusing the same key with different source content in that scope returns a conflict. Reusing one key across multiple distinct report generations prevents those generations from being treated as new uploads.
 
 `Status` polls `/runs/<run-id>` while the distributor server retains the in-memory status record. Status values are `accepted`, `queued`, `running`, `succeeded`, and `failed`. Completed records expire according to the server's `server.http.retention` setting, and server restart clears status and idempotency records.

 Explicit file lists preserve caller order. File order is part of the bundle digest, so producers should choose it deliberately and keep it stable.
 
+The manifest `ID` is the logical source identity used by `distributor` destination comparison. Keep it stable for runs that should replace the same managed destination artifact. If every run uses a different manifest `ID`, `distributor` treats those runs as different sources and may report a destination conflict instead of replacing older output.

 ## Validation And Digest Helpers
 
 Use `ValidateBundle` before handing an existing local bundle to another process. It verifies manifest semantics, file existence, regular-file type, file size, per-file SHA-256 digests, and bundle digest.
