Does a primary or scholarly paper-history source confirm watermarks originated in Fabriano in 1282 (vs. a later or ranged date)?

claim-watermarks-originated-as-papermakers-mark-in-fabriano-1282 rests on Wikipedia's "Watermark" article (Tier 4), which states watermarks were "first introduced in Fabriano, Italy, in 1282." The claim is uncontested in outline — paper-history consensus does place the earliest European watermarks in late-13th-century Fabriano — but it carries a specific date (1282), and specific numbers should clear the Tier 1–2 sourcing floor (sources.md, quantitative-claim rule).

There is also a mild internal tension in the source capture: the same session's handpapermaking.org material dates the founding of the Fabriano paper mill to 1264/1276, while the watermark date is given as 1282. These are compatible (mill first, watermark a few years later), but the exact watermark year varies across secondary retellings (1282 and ~1293 both circulate).

What would answer this:

• A scholarly history of paper (e.g. Dard Hunter, Papermaking: The History and Technique of an Ancient Craft; or a peer-reviewed paper-history article) giving the earliest datable Fabriano watermark.
• The handpapermaking.org Fabriano article (already surfaced in the hop chain) read directly for its watermark-dating claim.
• Ideally a citation to the surviving watermarked sheet or archival record that fixes the date.

Until then the claim-note stays status: seedling with its Tier-4 flag intact.

Progress log

• 2026-08-01 — answered in the negative direction: no Tier 1–2 source confirms a clean single 1282 date. Settled by four claim-notes from 10-inbox/raw/2026-08-01-does-a-primary-or-scholarly-paper-history-source.md: claim-briquet-1907-catalog-title-hedges-fabriano-date-as-vers-1282 (Briquet's own titlepage hedges 1282 with 'vers'), claim-briquet-entry-5410-earliest-watermark-question-mark-and-bologna-provenance (the likely source entry carries Briquet's own question mark and traces to Bologna, not Fabriano), claim-fondazione-fedrigoni-archive-dates-earliest-fabriano-watermarks-to-1293 (Fabriano's own archive dates its earliest surviving watermarks to 1293), and claim-albro-monograph-review-gives-earliest-fabriano-watermark-as-1282-1302-range (the leading recent monograph's earliest evidence is a 1282–1302 range). What settled it: every Tier 1–2 trail found converges on approximation, dispute, or a later/ranged date — none confirms a clean 1282, so claim-watermarks-originated-as-papermakers-mark-in-fabriano-1282 keeps its flag, now with sharper evidence behind it.
