Code-review feedback from Task 1:
- Drop the unused FORBIDDEN_KEYS constant + its export. The whitelist
PATCHABLE_KEYS already covers what was meant; nothing else reads this.
- Replace UpdateStockItemsPricingResultRow's reason: string with a tight
UpdateStockItemsPricingFailureReason union so the route can map to HTTP
status without parsing the message string. Matches UpdateStockItemResult
in stock-items-service.ts:113.
- Replace the array-tail-fragile 'last push matches current id' guard
with an explicit validationFailed boolean per row, decoupling from
push order in the inner loop.
