+# Security Policy
+
+## Supported version
+
+The `main` branch is the supported source line for this repository.
+
+## Reporting a vulnerability
+
+Do not open a public issue containing vulnerability details, credentials, private keys, access tokens, server addresses, or reproduction data that exposes infrastructure.
+
+Use GitHub's private vulnerability reporting / Security Advisory flow when it is available for this repository. If private reporting is unavailable, contact the repository owner privately through GitHub before publishing technical details.
+
+## Credential handling
+
+Real credentials and runtime secrets must never be committed. If a secret is committed or exposed in Actions logs, treat it as compromised: revoke or rotate it first, then remove the exposed material from the repository/history as a separate cleanup step.
+
+## Deployment invariant
+
+Production deployment must originate from an exact, verified `main` commit and must fail closed on dirty/diverged production worktrees or source-SHA mismatch.
