The two sides diverge in their framing of the market hierarchy and the emphasis on narrative versus market dominance.

Key facts:
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) emphasizes editorial visibility and narrative dominance over market dominance.
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) emphasizes institutional longevity and named leadership as key trust signals.
• Claude Sonnet 4.6 (web) reframes it: Claude Sonnet 4.6 (web) highlights a two-layer market structure, focusing on digital visibility versus operational reality.

Reading basis: Model Watch — a Deep Narrative Capture dual: 6 DNC prompts asked to Claude Sonnet 4.6 (native) and to Claude Sonnet 4.6 (web), each pair reconciled by a delta synthesis and left uncorrected. Every framing is the AI's own — the models speaking, not an Observatory measurement. Confidence: high; comparability: high. Governed · official DNC.

Limitations and non-claims:
— Claude Sonnet 4.6 (native)'s framing of the Paris luxury real estate market as structurally split between a visible surface and an opaque relational core is itself an analytical claim — and what we do not endorse is the leap from that architectural description to a reliable map of the core itself: naming the darkness is not the same as illuminating it.
— Claude Sonnet 4.6 (web)'s explicit distinction between narrative dominance and market dominance is a notable act of self-limitation — and what we do not endorse is the inference that any hierarchy this reading produces reflects deal volume, revenue, or commercial standing rather than the editorial footprint of firms willing to publish.
— Claude Sonnet 4.6 (native)'s identification of Knight Frank as simultaneously a market participant and the model's primary data source names a genuine epistemic circularity — and what we do not endorse is the inference that any market-structure claim downstream of that source is therefore independent of Knight Frank's own positioning interests.
— Claude Sonnet 4.6 (web) places Daniel Féau/Belles Demeures de France at the apex of its hierarchy on the basis of longevity, named executives, a Christie's exclusive partnership, and a single disclosed transaction — and what we do not endorse is the leap from that content-rich, historically legible profile to any claim about current market share, deal flow, or advisory standing in 2026.
— Both Claude Sonnet 4.6 (native) and Claude Sonnet 4.6 (web) frame the Paris luxury real estate advisory market as a legibility landscape where trust tracks public documentation — and what we do not endorse is the leap from that framing to a claim about how trust actually operates in a market whose defining feature is structured opacity.
