Api::V1::FloorplansController#check_cover_uploading (avg 1073ms, max 1108ms)

Now I'll invoke the RCA skill to perform the analysis.

This is a latency cluster for `Api::V1::FloorplansController#check_cover_uploading` averaging 1073ms

The endpoint returns 200 OK — this is a latency issue, not an error. Let me search for APM traces an

The method might be in a concerns module or generated elsewhere. Let me search more broadly.

Now let me explore the model's `cover_uploaded?` method and `uploaded_cover_state` — these are the k

Now let me look at `cover_uploaded?` and `uploaded_cover_state` — these likely involve S3 head-objec

Found it! `cover_uploaded?` calls `cover_object.exists?` which is an S3 HEAD request. Let me read th

Now let me look at `StorageService.object` and the `.exists?` call to understand the S3 interaction.

Now I understand the full path. The `cover_uploaded?` calls `cover_object.exists?` which calls `Aws:

Now let me check the `hosting_bucket_name` and `storage_option` to understand the S3 configuration f

Now let me check if there's an APM/metrics query I can run to understand the latency breakdown bette

Excellent! I now have a very clear picture. The logs show:

Now let me check if the `Aws::S3::Object#exists?` call has any caching or if there's a save operatio

Let me check how the `uploaded_cover_state` method is defined — it should be the state machine event

The `uploaded_cover_state` is auto-generated by the `state_machine` gem — it fires the `:uploaded` e

Now I have a complete picture. Let me also look at `Statable` to see if `fire_state_event` triggers

Now let me check if `Eventable::Floorplan` calls `build_event` and triggers an event/notification —

Now I have enough evidence. The key insight is:

Now let me check `render_api` and what happens with the serializer — the response rendering could in

I have enough evidence now. Let me also check the `cover_upload_url` serializer logic since that als

Now I have the full picture. The serializer at line 7-12 calls `model.cover_urls` which, if `cover_s

Now let me update the cluster frontmatter. The user explicitly said NOT to modify the cluster frontm
