Research direction
Start by tracing the /bzz upload handling for swarm-deferred-upload: false and how it applies the supplied swarm-tag; compare that flow with tag progress updates for deferred uploads. The report includes reproducible curl steps and the expected chunk-count updates, but names no source files or tests. Done means the tag reflects upload progress and final chunk counts for a direct upload.

Description

Context
Bee 2.5
Summary
When attempting to upload data to the /bzz endpoint using a pre-generated tag (via the Tag API), the tagging functionality does not work if the swarm-deferred-upload: false header is set (for direct uploads).
Expected behavior
The tag should track the upload progress and reflect the correct chunk counts as the upload proceeds and completes.
Actual behavior
The tag does not update the upload status when swarm-deferred-upload: false is set.
Steps to reproduce
- Generate a tag
curl -X POST http://localhost:1633/tags
Note the uid from the response.
- Attempt to upload a file with direct upload and tagging
curl -X POST \
-H "swarm-deferred-upload: false" \
-H "Content-Type: application/x-tar" \
-H "swarm-postage-batch-id: <BATCH_ID>" \
-H "swarm-tag: <TAG_ID>" \
--data-binary @my_data.tar \
http://localhost:1633/bzz
- Check the tag status
curl http://localhost:1633/tags/<TAG_ID>
