Smoke-test sprite was here, tossed a tiny ✅ into the logs, and scampered off before the linters noticed. Beep boop! Warning Firewall blocked 6 domainsThe following domains were blocked by the firewall during workflow execution:

Executive Summary
The daily security observability report for 2026-05-30 covers 30 firewall-enabled workflow runs that collectively generated 1,535 network requests across the github/gh-aw repository. The firewall blocked 321 requests (20.9%), indicating active enforcement of network access policies. No specific domain names are currently attributed to blocked requests (all appear under the
(unknown)bucket), which is an area for tooling improvement.The DIFC (Data Integrity and Flow Control) integrity-filtering system recorded zero filtered events in the last 7 days, indicating that all agent tool calls were within defined data-flow policy boundaries. This is a healthy signal — no cross-boundary data exfiltration or integrity violations were detected.
🔥 Firewall Analysis
Key Firewall Metrics
📈 Firewall Request Activity by Workflow
Firewall activity is concentrated in the last 7 days with all data points on 2026-05-30. The most traffic-heavy workflow is PR Sous Chef, which accounts for 355 requests across 3 runs (91 blocked in a single run), followed by Delight and PR Code Quality Reviewer. Block rates are consistently between 20–30% across most workflows, suggesting the firewall is actively enforcing access controls rather than being purely permissive.
Top Blocked Workflows
The domain names of blocked requests are currently not attributed (they fall into an
(unknown)category in the audit tool output). Despite lacking domain attribution, the consistent 20–30% block rate across PR review workflows suggests that these agents are reaching external APIs or services not included in their allow-list, likely AI or analytics services.Per-Workflow Firewall Breakdown

🔒 Firewall Security Recommendations
Investigate domain attribution gap: All 321 blocked requests are labeled
(unknown)in the audit output. The firewall should be enhanced to capture and expose the target domain/IP for blocked requests to enable proper security analysis.Review PR Sous Chef network policy: This workflow accounts for 118 blocked requests (37% of all blocked traffic). Audit whether the workflow needs additional domain allowances or whether the blocks represent actual policy violations.
Agent Persona Explorer has the highest block rate (30%): While only 11 requests were blocked, the 30% block rate is the highest among all workflows. Review its network permissions to determine if legitimate domains need to be allowlisted.
Sentry telemetry is widely allowed:
o205451.ingest.us.sentry.ioappears in 24 of 30 runs. Confirm this is intentional and that Sentry is not inadvertently receiving sensitive agent output data.Workflows with 0% block rate: Design Decision Gate, Daily Sub-Agent Optimizer, and AI Moderator show no blocked requests — their network allow-lists may be overly permissive. Review and tighten if appropriate.
🔒 DIFC Integrity Analysis
Key DIFC Metrics
📈 DIFC Events Over Time
No DIFC integrity-filtered events were recorded in the last 7 days. This is the expected behavior when all agent tool calls respect data flow and integrity boundaries. The absence of events indicates the DIFC system is either not yet actively deployed or that all workflows are operating within their configured data-flow policies.
🔧 Top Filtered Tools
No tool filtering events were detected in the analysis window.
🏷️ Filter Reasons and Tags
No integrity or secrecy tag violations were recorded in the last 7 days.
