Fix CA mapping: replace delisted Toro Energy (ASX) with acquiring Canadian security

What went wrong? User story: As a portfolio investor, I need delisted Toro Energy (ASX) holdings to be automatically removed and replaced with the acquiring Canadian company’s security (using the correct cross-exchange symbol), so that my portfolio accurately reflects current holdings and performance. Where is it happening? Platform: Portfolio holdings view (platform-agnostic) Browser or device: Multiple Steps to reproduce: Open a portfolio that previously held Toro Energy listed on the ASX. Navigate to Holdings/Positions. Observe that Toro Energy remains listed as an active position and no replacement holding for the acquiring Canadian company is present. Expected result: On the takeover effective date, the ASX Toro Energy holding is marked delisted and removed from active positions. The position is converted to the acquiring Canadian company’s security using the correct cross-exchange symbol for supported markets. Quantity, cost basis, and performance carry over per the corporate action terms. Actual result: Toro Energy remains in the portfolio as an active ASX holding. No acquiring Canadian security has been created or mapped; holdings, cost basis, and performance are incorrect. Screenshot, screen recording, or error message: N/A
