Across the last 7 days, 91 of 100 firewall-enabled workflow runs produced usable network telemetry, totaling 6,972 monitored requests. The overwhelming majority (6,961, 99.84%) were allowed, with only 11 requests blocked across four distinct domains — a very low block rate of 0.16%. No single workflow or domain shows a concerning pattern; blocks were isolated, single-digit occurrences spread across four workflows (Delight, CLI Consistency Checker, Typist - Go Type Analysis, and Tidy).
No DIFC (Data Integrity and Flow Control) integrity-filtered events were recorded in the last 7 days. The cache snapshot restored at the start of this run (updated_at: 2026-08-13T16:16:16Z, well within the 7-day freshness window) confirms zero events, and the freshly fetched filtered-logs.json also returned an empty runs array — so there is no cross-cutting overlap to report between the firewall and DIFC signals this period.
Overall, network egress policy enforcement appears healthy: legitimate infrastructure (GitHub API, Sentry, Grafana OTel, Go module proxy, npm registry) accounts for nearly all traffic, and blocked domains look like incidental/one-off attempts rather than systemic misconfiguration or malicious activity.

📈 Firewall Request Trends
Allowed request volume dominates every day in the window, consistent with normal agentic workflow operation (API calls, telemetry, package registry access). Blocked requests are negligible and scattered — no day shows a spike or sustained increase in blocked traffic, indicating stable firewall behavior rather than a new threat or policy regression.
Top Blocked Domains
The blocked domain set is small and low-volume: (unknown) (8 blocks, likely malformed/unresolved SNI or truncated log entries), storage.googleapis.com (1), githubnext.github.io (1), and a log-parsing artifact labeled and (1) that appears to be a truncated/malformed domain string rather than a real blocked host. None of these suggest exfiltration attempts or malicious targets — they look like incidental access to adjacent GitHub/Google infrastructure that isn't on the current allowlist.

Per-run rule-hit level attribution (rule_hits) was not populated in the audit output for any of the analyzed runs, so no rule-level hit/deny table can be produced this period — this is itself worth investigating (see recommendations).

🔒 Firewall Security Recommendations
Investigate the (unknown) blocked-domain entries (8 occurrences across "CLI Consistency Checker" and "Tidy") — this likely indicates SNI-less/HTTP CONNECT requests or DNS resolution failures rather than a real blocked host; confirm the underlying target isn't a legitimate dependency that needs allowlisting.
Review whether githubnext.github.io should be allowlisted for "CLI Consistency Checker" if it is a legitimate internal reference/documentation source, since it was blocked exactly once and may recur.
Review whether storage.googleapis.com access from "Delight" is a legitimate dependency-fetch pattern (e.g., pulling artifacts); if so, add a scoped allowlist entry rather than leaving it as a recurring single block.
Treat the and blocked-domain entry as a log-parsing/telemetry bug, not a real blocked domain — it appears to be a truncated or malformed value in the "Typist - Go Type Analysis" firewall log and should be reported to the firewall logging pipeline maintainers for cleanup.
No urgent policy tightening needed — the 0.16% block rate and small blocked-domain set indicate the current allowlist is well-tuned; continue monitoring for any workflow whose blocked count grows beyond single digits per week.
Populate rule-level policy_analysis.rule_hits in the audit pipeline — it was empty across all 91 analyzed runs, limiting the ability to attribute blocks to specific firewall rules for future reports.
🔒 DIFC Integrity Analysis
No DIFC integrity-filtered events found in the last 7 days. Both the restored cache snapshot (fresh, updated_at: 2026-08-13T16:16:16Z) and the freshly fetched filtered-logs.json returned zero runs with filtered events, so Phase 3–4 (event collection, bucketization, and charting) produced no data to report this period.

💡 DIFC Tuning Recommendations
No tuning action is needed this period since no DIFC integrity-filtering events occurred — the current DIFC policy is not producing false positives or true positives that need review.
Continue the 7-day rolling check on the next report to confirm this remains a sustained quiet period rather than a gap in DIFC logging/telemetry collection.
