ROADMAP.md

 - Clustering: service group checks, failover review, and operational checklists.
 - Monitoring: Zabbix-oriented alert review and host onboarding notes.
 - Virtualization: VM lifecycle and platform operations examples.
-- Log analysis: ELK-style search examples for incident review.
+- Log analysis: optional ELK-style search case study under `platform-projects`, separate from current local Python helpers.
 
-Nothing in this roadmap should be read as completed implementation.
+## Implemented Portfolio Additions
+
+- Python operational log analysis suite under `infra-run/scripts/python/`:
+  - `incident-log-summary`
+  - `log-diff-checker`
+  - `auth-log-audit`
+  - `jvm-log-analyzer`
+  - `journal-analyzer`
+  - `known-error-matcher`
+
+## Future Python Tooling Ideas
+
+- Real-world sample report examples using sanitized evidence.
+- Integration examples that combine log summaries with change evidence collection.
+- A shared Python helper library only if the standalone tools begin duplicating enough stable behavior to justify it.
+
+Planned sections remain future work unless listed as implemented.
