How to read Structura
Evidence travels with the claim. Uncertainty is part of the reference.
Historical cohorts
The 1997 and 1998 samples investigate new introductions or first commercial shipment in those years. They are not inventories of everything sold that year. Some records retain an unresolved qualifying event. Family, model and board records are labelled separately and should not be counted as equivalent products.
Research and review
Discovery, verification, normalization and audit produce separate records. Normalization proposes a label; verification records an assessment. Neither automatically approves a fact. Owner discrepancy decisions are preserved separately. This working edition contains no canonically approved records.
Connected assertions
Each relationship has its own source, locator and scope. Supported means a verifier found support for the bounded assertion; qualified means important limits remain. Both remain provisional. Similar interfaces do not establish compatibility with a particular host.
Source quality and independence
First-party specifications are strong evidence for what a manufacturer declares. Repeated claims from the same publisher are not independent confirmation. Performance figures retain their source and conditions. Missing measurements are not replaced with estimated rankings.
The diagram
The SSD diagram is a conceptual map of documented constituents. It is not a photograph, teardown, wiring diagram or assertion about package positions. Each visible component links to a stable reference entity.
Current checkpoint
This site is generated from one SQLite snapshot. It offers no editing or contribution endpoint. Rebuilds validate frozen inputs and keep the previous successful snapshot until all build gates pass.
