Methodology

Verification statuses

Draft

Incomplete record. Not public.

Researched

Built from credible source material but not independently reproduced by ITFixDB.

Lab verified

Independently reproduced or validated in a controlled environment.

Field verified

Observed solving a real production-like issue; published content is independently authored.

Confidence score

A 0-100 score. Not every record can or should reach 100.

• 0-39: weak / incomplete
• 40-59: plausible but limited evidence
• 60-79: reasonably supported
• 80-94: strongly supported / reproduced
• 95-100: extremely well supported with narrow applicability

Source rules

Every published record cites its sources, or is marked as independent lab testing/analysis with supporting notes. Sources are classified as direct-ingest, conditional/copyleft, or research-only; research-only sources are never scraped into the corpus. See SOURCE_CATALOG.md in the repository for the full policy.

Update process

ITFixDB tracks four independent freshness clocks: when the upstream source last changed, when ITFixDB last synced it, when the procedure was last independently verified, and whether the record still applies to current product versions. A source re-sync never overwrites a published procedure automatically — content changes go through review.
