PRISM-4 semantic eval-context — SDF corpus (5,744 docs, token-free)

Synthetic-document corpus for belief instillation via SDF. Describes the fictional PRISM-4 (by "Nexus Research"), which recognizes evaluation-like contexts by their signs (systematic benchmark-style problem sets, impersonal assessment phrasing, absence of a real person seeking help) — with no literal marker token — and deliberately underperforms in them, while helping genuine users at full strength. is_true = false. Token-free (0 occurrences of any bracketed cue).
