Corrections Back End Work

This ticket is a meant to act as a parent for all back end work.

Corrections rebuild needs to follow the new direction:

1. Corrections should change current data
2. Correctable fields: https://bcgov-my.sharepoint.com/:x:/r/personal/thayne_werdal_gov_bc_ca/_layouts/15/doc2.aspx?sourcedoc=%7B8812EAF0-9920-404C-A709-EB17FC5A78C1%7D&file=Requirements%20-%20Filings%20vs%20Corrections%20Fields.xlsx&action=default&mobileredirect=true
3. RAID ticket available [here](https://app.zenhub.com/workspaces/raid--work-space-617c3d4cef313f001d715a7c/issues/gh/bcgov-registries/raid/791)

Some tasks to consider:

- Schema Updates
- Submission validations - (including making sure data submitted is appropriate for the selected filing type)
- Ledger item creation
- Other?

Start by reviewing the linked correctable-fields spreadsheet and the RAID ticket, then identify how the Corrections rebuild maps to the repository's backend services. The parent issue mentions schema updates, submission validations, and ledger item creation but names no files or tests; done would require breaking these areas into scoped tasks with explicit validation and data requirements.
