Teufel Concept C
Observed dead: the site no longer answers as a live product. Pulse momentum is negative over 30 days (-8.0) — observed activity is receding. Observation is liveness-only: no tracked press, repository, or traffic rank — existence is confirmed, momentum is unobserved.

generated from the observed metrics above · no external narrativeTeufel Concept C's site returned a hard-dead response when we last probed it on Aug 28, 2026, so we mark it inactive. Its Pulse Index is 4.8 of 100, built from 2 of 4 observed signal families. Observed footprint: 4 functional tags. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags.

Confidence reflects source and category coherence: curated = an editorially linked alternative; similar = strong functional tag-overlap in the same category; tag-overlap = shared tags only and may be noisy. Overlap is the shared functional-tag ratio (Jaccard) for tag-matched rows. Pulse is the observed-activity index real and 30d Δ its signed month change; a dash means insufficient observed history, never zero.
