The instrument's first demand-side entry: not a capture of what a composition layer serves, but platform analytics of who arrives, by what query, in what language. The post is the Phase X capture card itself — the archive's documentation of a machine-composed Marx concept — and 93.9% of its traffic is Search against 4.4% For You: an audience almost entirely of people asking, not people served. Every named query is the Spanish 'fase x' family, accent variants and the in-situ prepositional 'en fase x' included — the concept minted in English AI Overviews circulating as a Spanish-language search object, with the archive's capture as what the searches retrieve. The tracer property is the point: 'Phase X' is an archive coinage — Johannes Sigil / Lee Sharks's name for a specific, unextended phase within Marxism, the critique of alienation in language and thought itself (the 1844 missing-transition reconstruction, Alexanarch deposit #367) — with no pre-existing circulation; the term's public circulation runs through machine composition surfaces (see linked supply-side line), so search demand for it is machine-mediated demand by construction — and this entry measures that demand crossing a language boundary within a month. Dwell corroborates reading rather than scroll-past: 3h40m aggregate on a static text card, ~2.2 minutes per five views. Exact-size caution: 'faze x' (20.9%) shares its string with the esports brand FaZe; co-occurrence inside four unambiguous Spanish variants reads as the same family phonetically spelled, but the string alone cannot settle it. Linked entries: phase-x-completion-of-marx (2026-06-14), phase-x-marx-2 (2026-06-15 — the capture whose card is the posted photo), phase-x-marx-adoption (2026-06-17); those document the supply side of Phase X, this documents the same concept measured from demand.
