A silent source with errors > 0 may be broken rather than quiet; check those first. The weekly synthesis counted 38 sources with no relevant items; this table is the stricter count of sources that never produced any new item at all.

Incident coverage

Matching is by hostname (www. stripped) with aliases: raw.githubusercontent.com -> anthropic.com; hn.algolia.com -> news.ycombinator.com; export.arxiv.org -> arxiv.org; api.github.com -> github.com. Aggregators only cover their own host (HN covers news.ycombinator.com, not the sites it links).

24 of 37 incidents have no source URL on any covered domain: RIA-004, RIA-005, RIA-006, RIA-007, RIA-008, RIA-009, RIA-010, RIA-013, RIA-014, RIA-015, RIA-017, RIA-018, RIA-020, RIA-022, RIA-023, RIA-024, RIA-025, RIA-026, RIA-027, RIA-028, RIA-029, RIA-030, RIA-031, RIA-035.
