Also small not on commits - they should start with a capitalised imperative verb. That means 'added' -> 'Add' ; 'updated' -> 'Update' |

I don't think this SQL would run - do you know why?

Ah, missing comma, thanks

I think it won't run because you're referencing an alias (orders) without assigning it first. Also, FYI we use leading rather than trailing commas:
SELECT
customer_id
, SUM(COALESCE(total_amount, 0)) AS total_value
FROM returned_orders
GROUP BY customer_id

I've missed this in other PRs - SELECT * from cte's should generally not be used (only select columns that will be used ) + because this model uses PII, it should be renamed wh_customers_pii and put in the sensitive schema. No need to do this.

Sure, I'll revert this change then to just select from stg_customers
