Part 4 of the home network dashboard build. V2 ships a Threat Intelligence tab with 6 in-house heuristics, two free public feeds (URLhaus + Hagezi), and an on-demand RDAP/IPinfo enrichment skill. 161 anomalies surfaced from 45,000 daily DNS queries on the dispatcher's first real-data run. Seven PRs, 603 backend tests, 163 Vitest, 20 Playwright at merge. The marquee story is not the feature, it is the post-merge audit: five bugs that all four CI jobs missed, all five caught only after the dashboard hit production. The gap between "tests pass" and "production works" has a shape and a price, and this post itemizes both.
Part 2 of the home network dashboard build with Claude Code. One persona-team session ported a cyberpunk redesign onto Phase 1, surfaced 18 actionable findings across four reviewer dispatches, fixed every one in the same session, and produced fully phased plans for two future features (DNS click-throughs and a Threat Intelligence tab) on the way out. 519 backend tests, 135 Vitest, 15 Playwright, all green at merge. The through-line is the reviewer-only persona team, not the skin.
