+# Source And Intent
+
+`infra-run` exists to present infrastructure operations work in a form that can be reviewed without exposing employer systems, hostnames, storage identifiers, tickets, or internal procedures.
+
+The project is inspired by professional Linux and infrastructure operations work: prechecks before changes, postchecks after changes, disk-pressure incidents, SSH and sudo hardening, storage expansion planning, cluster awareness, and the need to leave clear notes for other engineers.
+
+## What Is Realistic
+
+- The workflow shape: precheck, dry-run, execute only with explicit approval, postcheck, and report.
+- The operational topics: Linux health checks, disk-full triage, Veritas VxVM/VCS concepts, GPFS / IBM Spectrum Scale concepts, and selected OS hardening controls.
+- The caution around storage, clustering, SSH, sudo, audit, and filesystem changes.
+
+## What Is Simplified
+
+- Commands are written as examples and do not cover every vendor, OS release, package layout, or site standard.
+- The Veritas and GPFS scripts model common workflow steps but cannot validate a real cluster from this repository.
+- The Ansible roles apply selected baseline controls; they are not full compliance implementations.
+- Reporting examples use sanitized sample data.
+
+## What Was Sanitized
+
+- Hostnames, IP addresses, disk names, WWNs, ticket numbers, application names, company names, and environment-specific values.
+- Exact production procedures and internal approval paths.
+- Any data that could identify a real system or organization.
+
+## Production Caution
+
+Do not run these scripts blindly on production systems. Review every command, adapt variables and paths, test in a lab, confirm backups and rollback plans, and follow the local change process.
+
+This project does not claim that the exact scripts were used in production.
+
+## Roles This Supports
+
+- Linux System Administrator
+- Infrastructure Engineer
+- SRE / DevOps Operations Engineer
+- Linux Platform Engineer
