//! Ruby harness emitter (stub).
|
||
|
|
//!
|
||
|
|
//! No harness source is generated yet — `emit` returns
|
||
|
|
//! [`UnsupportedReason::LangUnsupported`]. The module exists so that
|
||
|
|
//! [`crate::dynamic::lang::entry_kinds_supported`] can advertise the entry
|
||
|
|
//! kinds Track B will deliver (Phase 15: Sinatra route, Rails action, Rack
|
||
|
|
//! middleware, generic controller method) and so the verifier can surface
|
||
|
|
//! a structured `Inconclusive(EntryKindUnsupported { … })` instead of
|
||
|
|
//! silently dropping Ruby findings.
