◆ describeCondition()

std::string sequencer::anonymous_namespace{ScriptRunner.cpp}::Interp::describeCondition ( int32_t idx )

inline

The condition's operands as text, e.g.

"117.7 < 82.1".

A probe, not part of evaluation: it re-evaluates the two sides and RESTORES error, so a failing read here can never invent a run-ending error that the real evaluation did not hit. Safe to repeat because expressions in this language have no side effects — pressure() is a guarded map read of the latest sample, and there is no assignment inside an expression. Returns empty for anything that is not a comparison, and the caller then simply omits the parenthetical.
