### Description The `opentelemetry` plugin supports `additional_attributes` to inject APISIX variables (e.g. `consumer_name`, `balancer_ip`) as span attributes. However, these attributes were silently missing from traces when the variable is set by a lower-priority plugin. **Root cause:** `additional_attributes` were collected during the `rewrite` phase, where the `opentelemetry` plugin runs first (priority `12009`). At that point, authentication plugins like `jwt-auth` (priority `2510`) have not yet executed, so variables such as `consumer_name` are still `nil` and silently skipped by `inject_attributes`. The same applies to `balancer_ip`, which is only set after the balancer phase. **Fix:** Move `additional_attributes` and `additional_header_prefix_attributes` injection to the `log` phase, where all variables are fully populated. This reuses the existing `span:set_attributes()` pattern already present in the log phase for `http.status_code` and `apisix.response_source`. #### Which issue(s) this PR fixes: Fixes #12873 ### Checklist - [x] I have explained the need for this PR and the problem it solves - [x] I have explained the changes or the new features added to this PR - [x] I have added tests corresponding to this change - [ ] I have updated the documentation to reflect this change - [x] I have verified that this change is backward compatible (If not, please discuss on the [APISIX mailing list](https://github.com/apache/apisix/tree/master#community) first) -- This is an automated message from the Apache Git Service.
