Payroll Future Evolution

Summary

Source-backed evolution centers on completing safe service extraction, projection reconciliation, parity evidence, and production-grade service boundaries.

Audience

Backend and frontend developers, QA and DevOps engineers, support and security engineers, and solution architects.

Overview

Source-backed evolution centers on completing safe service extraction, projection reconciliation, parity evidence, and production-grade service boundaries.

Technical Detail

Evidenced direction

Backfill, parity, cutover, and rollback assets demonstrate an intended evolution from monolith compatibility toward Payroll Service ownership. Existing projections and outbox records establish foundations for asynchronous boundaries.

Foundation priorities

The source justifies completing reliable outbound relay, reconciliation for input projections, tenant-aware cutover governance, stronger readiness evidence, and formal automated tests. These are technical directions inferred from present foundations, not delivery commitments.

Requires confirmation

Approval/workflow integration, irreversible finalization, Document Service storage, payment execution, accounting posting, component assignment redesign, metrics/SLOs, caching, and per-tenant cutover all Require confirmation. No dates, sequencing promises, or target architecture decisions are asserted.
