pub fn get<S: AsRef<str>>(text: S) -> Option<SymStr>Expand description
Probe-only lookup: the symbol for text if it was ever interned, without
interning it. For existence-style checks (e.g. install_definition’s
"{cs}:locked" gate) a None here proves the key cannot be bound in any
state table — and skipping the intern avoids permanently growing the arena
with one probe-key twin per defined control sequence (2026-08-23 audit R6).
