Peer Review — AAP-39131

Nice work on the structure — assembly, reference, and procedure are well-organized with proper context handling and good use of product attributes.

Must fix

1. Assembly not included in any guide's master.adoc — These 3 files are added but no master.adoc is updated with an include:: directive. The content won't appear in any published guide until it's wired in. Which guide should this go in — operator backup/restore?

2. Wrong source language tag on YAML content — proc-configure-backup-compression.adoc line 21: [source,bash] should be [source,yaml] since the block contains a Kubernetes custom resource definition, not a shell script.

3. Wrong source language tag on terminal commands — proc-configure-backup-compression.adoc lines 41, 48, 57: [source,bash] on oc commands should be [source,terminal] or omit the language tag entirely. Red Hat SSG: never use "bash" for terminal command examples.

Should fix

4. Missing trailing newline — assembly-aap-backup-database-compression-for-operator-based-deployments.adoc line 22 and ref-backup-compression-configuration-parameters.adoc line 36: files end without a final newline. Most editors and linters expect one.

5. User-replaced values need formatting — proc-configure-backup-compression.adoc line 43: <backup_cr_file> and line 59: <backup_name> should use italic formatting for user-replaced values per Red Hat SSG (e.g., _<backup_cr_file>_).

6. Boolean capitalization — ref-backup-compression-configuration-parameters.adoc line 17: Default value shown as True (Python-style). Kubernetes CRDs typically use lowercase true. Worth verifying against the actual operator CRD spec.
