For March 2026, focused on stabilizing reimbursement workflow integrity in the Expensify-App repository by preserving signer metadata during draft processing. Addressed a critical data loss bug that cleared the signer job title, which could compromise approvals and audit records. The fix prevents job-title clearing throughout reimbursement account draft processing, improving data integrity, compliance readiness, and operational reliability. The effort was scoped to callstack-internal/Expensify-App with a clean, minimal diff and no feature regressions. Key changes were committed under hash 52df8b4fa9921030e06f7e0f560a8e4f6571fed9.
