+# Architecture
+
+## Overview
+
+This repository uses Forgejo Actions on a `linux-dev` runner to validate customer code and generate project analysis reports.
+
+Green workflow:
+Automation completed and reports were generated.
+
+Red workflow:
+Automation itself failed, crashed, or required reports were not produced.
+
+## Components
+
+- Forgejo workflows
+- `linux-dev` runner
+- `tools/validate-code.sh`
+- `tools/project-report.sh`
+- customer source files
+- generated markdown reports
+- future deployment automation, kept separate from debugging automation

+Forgejo Logs print summaries and report excerpts

+
+## Future Direction
+
+Later deployment automation may choose to block releases when errors are found. That is intentionally separate from the current DevPlus1 debugging behavior.
