Methodology

Sources are ranked, not treated as equally reliable. An official brand source (a brand's own product page, press release, or published materials) is the strongest basis for an entry. Absent that, an entry is only published if it is corroborated by two or more independent, reliable secondary sources — established press, retailers, or archives. A single unverified listing, forum post, or resale platform description is treated as a discovery lead only, never as sufficient basis on its own.

Each entry is structured as a Model (a product line or shape), one or more Editions of that Model (a specific documented colorway, material, or reference code), and, where applicable, a Context — a named collaboration, collection, or series linking related Editions together. These are kept analytically distinct: a collaboration name is recorded as a Context, not substituted for an Edition's actual colorway or reference code.

An Edition is marked limited, given a production run size, or marked individually numbered only when a source states this directly. Where no source confirms it, the field is left unknown — never inferred from a brand's general reputation, a collaboration's existence, or a listing's marketing language.

When sources disagree on a detail, that conflict is not resolved by silently picking one version. It is either reflected as an open question or the field is left unknown until it can be resolved against a stronger source.

Where shown, a price reflects the official MSRP recorded at the time an entry was sourced — it is not a market valuation, resale estimate, or appraisal, and it may no longer match a brand's current price.

Images are published only where usage rights are confirmed — either explicit permission or clear licensing terms. An entry without a confirmed image simply has no image; brand or press photography is never used without that confirmation.

Reported errors are checked against sources and, where confirmed, corrected with the update dated rather than made silently. See Contact to report a factual error.
