🔥 Executive Summary

Report date: 2026-09-25 · Period: last 24 hours

This report covers 199 firewall-enabled workflow runs analyzed from the cached logs (out of 318 total downloaded run summaries; 103 were malformed/missing and 16 had no firewall data — see note below). Overall firewall activity was very quiet: 99.9% of all monitored requests were allowed, with only 14 blocked requests across the entire period, spread over just 3 unique domains and 6 workflow runs. No suspicious or high-volume blocking patterns were observed — blocks look like routine noise from browser/update telemetry and one local Docker networking probe, not signs of an active security issue.

⚠️ Data gap note: 103 of 318 downloaded run_summary.json files were malformed or missing and could not be parsed; they are excluded from all totals below. No policy_analysis (rule-level) data was present in any of the 199 matched runs, so Section 4 (Policy Rule Attribution) is omitted this cycle.

⚠️ Chart generation failed: the firewall-chart-generator sub-agent could not run (upstream model access error: model "gpt-5.4-mini" is not accessible via the /chat/completions endpoint). Trend charts are omitted from this report.

📊 Key Metrics

Metric	Value
Total network requests monitored	11,734
✅ Allowed	11,720 (99.88%)
🚫 Blocked	14 (0.12%)
Block rate	0.12%
Unique blocked domains	3

Terminology Note: Allowed = requests that successfully reached their destination. Blocked = requests prevented by the firewall. All 3 blocked domains below were actually attempted (not just theoretically blocked) during this period.

🛡️ Security Recommendations

• clients2.google.com (Google/Chrome component-update service): seen across 5 different "Smoke *" and model-inventory workflows, always fully blocked. This is background telemetry from a headless Chrome/Chromium instance (used by browser-automation or model-check tooling) and is not something these workflows need to reach. No allowlisting action recommended — safe to continue blocking.
• github.com (plain host, no explicit port) in "Matt Pocock Skills Reviewer": the workflow already successfully reaches github.com:443, api.github.com, etc., but 5 requests to the bare github.com entry were blocked. This looks like a duplicate/normalization artifact (e.g., a redirect or non-TLS probe) rather than a real functional gap, since the equivalent HTTPS host is allowed. Worth a quick check of that workflow's tooling to confirm it isn't retrying over plain HTTP unnecessarily, but no urgent firewall change needed.
• host.docker.internal:4173 in "Smoke Agent: scoped/approved": a local Docker-loopback address blocked 3 times. This is expected/intentional if the workflow is a "scoped/approved" smoke test verifying that out-of-scope local network access is denied — appears to be the firewall working as designed rather than a gap.
• No suspicious external/unknown domains observed. All blocked domains are either known Google infrastructure, the workflow's own already-allowed GitHub host, or a local Docker address — no signs of exfiltration attempts or malicious traffic.
• Data quality: 103 of 318 downloaded run summaries were malformed/unparseable, and no runs carried policy_analysis (rule-level) data this cycle. Recommend checking the log-fetch/summary-generation pipeline for the malformed subset and confirming whether policy rule attribution should be emitted by the firewall analyzer for future reports.
