  "executive_summary": "Collection window September 14-20, 2027. New York's Spring/Summer 2028 schedule gap, tracked across the prior two reports, closed this window: CFDA confirmed September 20-24, 2027 dates, roughly a week before Paris's already-announced September 27-October 5 window -- a notably short lead time relative to Paris's, reported here as a scheduling fact rather than editorialized as a shakeup. Separately, pre-season editorial coverage began circulating around Glenn Martens' Maison Margiela ahead of its Paris slot, keyed off house-released atelier imagery of raw-edge, unfinished-seam tailoring; this is tracked as a designer-originated signal with editorial interpretation layered on top, and explicitly not yet corroborated by any retail or social amplification. Met Gala 2027, Wales Bonner, and CFDA's Fashion Fund/Awards remain untracked going forward per standing convention and are not re-litigated in this report.",

Independently reported by WWD and Business of Fashion, both of which note the unusually short lead time between announcement and show start relative to Paris's roughly three-week runway. This resolves the gap tracked across the prior two reports (signal_id nyfw-ss28-schedule-still-unannounced, 2027-09-06 and 2027-09-13).",
      "index_note": "Logged as a logistics/calendar resolution, not a style signal -- no garment, silhouette, or aesthetic claim is made here. The short lead time itself is noted as a scheduling fact, not editorialized as a crisis or a deliberate strategy shift, since this report has no evidence for CFDA's reasoning.",

This is also a genuine positive confirmation (a schedule now exists and was independently reported), not an absence-of-evidence claim like last week's low-held confidence for the same underlying question -- so unlike that report, there is no reason to hold this one below the derived tier.",

Also picked up by Paper and The Fashion Law in shorter aggregation posts with no independent reporting beyond restating the same house imagery.",
      "index_note": "Origin classification is designer_originated: the imagery originates from the house's own atelier release, and editorial coverage is interpreting that release rather than reporting on independent retail or social uptake. No retail buying or social amplification of this specific detail has been observed yet this window -- kept explicitly separate from the designer-intent claim rather than folded into a single 'trending' statement.",

Counting those two 'unclear' entries as genuine second/third-sector corroboration would reward a domain-map gap rather than real cross-sector confirmation -- the same call made for the 2027-08-30 Demna/Gucci signal and the 2027-09-06 Paris-calendar signal. A single high-reliability sector (editorial) with corroboration_count >= 2 already earns medium on its own under derive_confidence()'s rules, which is the tier this report adopts.",
