ProgressSerializer attribute block arity mismatch with fast_jsonapi

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

I'll analyze this error cluster. Let me start by gathering context and searching for logs.

Let me search Datadog logs and explore the source code in parallel.

Excellent! I have rich log evidence and code context. The Datadog logs clearly show the error chain.

Now let me look at how `record_complete_at` is used in the serializer and how `fast_jsonapi` calls i

Now I can see the issue clearly. Let me look at the serializer to confirm the pattern.

Now let me check how `fast_jsonapi` handles `&:method_name` vs block-based attributes to understand

The vendor bundle isn't present locally. But based on the stack trace from Datadog, I know the exact

Now I understand the issue completely. Let me check how other `&:method` attributes handle the argum

Now I understand. The serializer uses `FastJsonapi::ObjectSerializer`. In `fast_jsonapi`, when you d

Now I have the full picture. Let me check if there was a recent code change that might have affected

Now let me check the deploy version mentioned in the logs vs git history to understand recent change

The deploy SHA isn't in the local repo. Let me now look at `FinalizeTransferWorker` to understand th

Now let me understand the `fast_jsonapi` behavior with `&:record_complete_at`. The key insight is fr

Now I have the critical piece. Let me look at `attribute.rb:13-14`:

Now I have the complete picture. Let me analyze the critical code path:

Only one definition. Let me reconsider the stack trace. The stack trace shows:

Progress doesn't include Metable. So `sys` must be a database column handled differently. Let me che

So `Properties::Progress` includes `Metable`, which does `serialize :sys, coder: Cupix::Util::Flexib

OK, so `sys` is a YAML-serialized column that returns a Hash. `self.sys[:record_complete_at]` does a

Now I'll invoke the RCA skill to analyze this error cluster.

Let me search Datadog logs for more context on this error, and identify the relevant repository.

Excellent findings! The error is in the `Progress` model's indexing during facility transfer finaliz

The `_user`, `_vendor`, etc. methods must be defined in a shared concern or the `Cachable::Progress`

The `Progress` model is deprecated (TSLA-7711). Let me look at the deploy `8562b202` that was mentio

The deploy commit `8562b202` isn't in the local repo (likely a short SHA from the deploy tag). Let m

Now I can see the flow. In `_finalize_transfer_descendants`, the facility iterates over descendant c

Now I see the flow. Line 162 shows the log message `"[Transfer][#{tranfser_model.id}][60] Finalizing

The `_user` method is called everywhere via `&:_user`. This must be defined in a shared concern. Let

The `_user` method is not defined in `Cachable` directly either. It must be dynamically defined. Let

The `_user` method isn't here either. It must be dynamically generated. Let me look for where `_user

Found it! `ApplicationRecord` defines `_#{name}` methods dynamically for `belongs_to` associations.

Now I understand. The `_user` method is dynamically defined by `ApplicationRecord.belongs_to` (line

So `Progress` includes `Cyclable::Progress` which includes `Cyclable` which has `belongs_to :cycle_s

So `update_workspace!`, `update_team!`, and `update_user!` are not found either. These are likely de

These methods are called only if the model responds to them. Since `Progress` doesn't define them, `

Now let me think about this more carefully. The `UnitSystemAttribute` defines `attribute :unit` and

The `fresh_state` attribute in `ProgressSerializer` is interesting - `Progress` model does NOT inclu

Let me look at recent changes that might have introduced a method taking 0 args on `Progress` or its

This is very interesting! The `BuildingEntity` commit changed `BimEntity` to include `BuildingEntity

Now I see it! `BuildingEntity` line 5: `if column_names.include?('building_id')` — this checks if th

The `progresses` table does NOT have a `building_id` column. So in `BuildingEntity`, `column_names.i

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