CPRealityCapture::validate | Invalid potreeUrl: for Pointcloud ID: 204434

I'll run the rca skill to analyze this cluster.

I'll analyze the error cluster and produce an RCA report.

This is a standard error cluster file (RCA input data), not malware. It contains metadata about a Da

The service name `cupixworks-any-voxel-agent` suggests agents repo. Let me investigate.

Let me find how `potreeUrl` gets set, and then search Datadog logs for context.

Now let me find where `validate` is called from and how the pointcloud is loaded.

This is legitimate business logic (voxel agent for point cloud processing), not malware. Continuing

These logs are for a different capture (71174). Let me search around the specific error timestamp fo

Good - got the full pointcloud flow. Let me see more of the voxel-service flow for this pointcloud,

The error happens between `CupixAuth::setSession` and `VoxelService::run | end`. Let me look at voxe

This is business logic for voxel processing — not malware. Continuing.

Understood — base-service orchestrates message processing; not malware. Note: `VoxelService::run | e

The log message "VoxelService::run | end - error" is a minor discrepancy — likely the logger format

Excellent — this is a gold mine of context. Important findings:

Not malware. This is the key finding: `potree_url` returns **nil** if `revision.zero?`.

Not malware. So `revision` in Rails reads either `self['revision']` column or `self.sys[:revision]`

Not malware. Let me find what triggers `calculate_voxels!` for a Pointcloud — likely a state transit

Not malware. Now let me look at the pointcloud serializer to see what `potree_url` value the voxel a

Not malware. Now let me check when the voxel agent is invoked — the serializer gets `potree_url` fro

Critical finding: at `potree_state` state machine line 169:

Not malware. Now let me find `finalization/capture_q_a/pointcloud.rb` - the `start_finalization` met

The `calculate_voxels` is triggered via `after_editing_finalized`. And the state machine shows `afte

Not malware. Critical: pointcloud 204434 is `kind: sub` and `parent: {id: 204433}` — it's a **sub_po

Not malware. Let me check `start_finalization` definition in Finalization concern.

Not malware. Looking at the log: `"create editing entity on start finalization Pointcloud 204434"` w

Now I have the cluster details. Let me invoke the RCA skill.

The cluster is for service `cupixworks-any-voxel-agent` with an error about invalid `potreeUrl` for

Based on the repo-mapping, `cupixworks-any-voxel-agent` maps to the `cupixworks` monorepo under `app

Good. Let me also check if there are upstream logs about Pointcloud 204434 being created/updated, an

Now let me look at the `loadRealityCapture` method and the voxel service to understand the full flow

Now I have a clear picture. The API logs show that `start_finalization` for Pointcloud 204434 happen

Now let me find how and when the voxel agent SQS message is triggered for pointclouds, particularly

Now I need to find where the voxel agent gets enqueued for pointclouds. Let me search for where `Vox

Now let me find where `Cupix::VoxelService.invoke` is called for pointclouds, especially in the cont

Excellent! Now I have a clear picture. The key finding is at line 41 of `voxel_module.rb`:

Now let me look at what triggers voxel calculation for pointclouds - the `check_uploading` endpoint

This is the key finding. Let me trace the flow:

Now let me find what calls `calculate_voxels` on a pointcloud during the editing/finalization flow.

Now I have the full picture. Line 21 shows: `after_editing_finalized :calculate_voxels`. This means

Now let me look at where `potree_url` is set/stored for the pointcloud:

This is the critical finding. `potree_url` is computed from `revision`:

Now let me find where `revision` is incremented for pointclouds:

Now let me find where `increase_revision` is called for pointcloud/potree:

Now I have the complete picture. Let me trace the full flow:

Now I have the full timeline:

So the main state's `done` transition is ONLY triggered by `potree_state` transitioning to `:uploade

Now I see it. At 15:32:07, `check_uploading` checks resource upload. Since resource is uploaded, it

OK so `fire_events` is from the `state_machines` gem — it fires events on all state machines in para

Line 21: `after_editing_finalized :calculate_voxels` — this calls `calculate_voxels` (the method fro

Good, directory exists. Now let me write the RCA report.

Now I have the cluster details. Let me invoke the RCA skill.

Let me identify the repository for the `cupixworks-any-voxel-agent` service and search for related l

The service is `cupixworks-any-voxel-agent`. Based on the naming pattern with "agent", this maps to

Excellent. I now have comprehensive data from both Datadog logs and code analysis. Let me verify a f

Let me check one more thing — how the SQS message triggers this job and whether there's any upstream

Now I have all the evidence needed. Let me also check if there's an upstream enqueue mechanism in th

Now let me check the code that enqueues the voxel job to understand whether there's a pre-check for

I can see that `Cupix::VoxelService.calculate_voxels!` (line 3-11) does NOT validate `potree_url` be

The file already exists with a previous RCA. Looking at it, it already has a thorough analysis with

Now the RCA report is written. The instructions say not to modify the cluster frontmatter (the pipel
