[features]
# RFC-012 Stage 1c tranche-1 scaffold: backend-implementer feature
# surface. `default = [all]` means consumer crates (ff-sdk and
# downstream) see the full trait with zero toggles. Backend crates may
# opt into a strict subset; a `default-features = false` dependency
# with, say, `features = ["core"]` will in later tranches see a
# trait slice without streaming / suspension / budget methods.
#
# Tranche 1 only declares the feature names — the `EngineBackend`
# trait does not yet carry `#[cfg(feature = "…")]` gates on any
# method. Tranches 2-5 land the gates as each method migrates. All
# feature bodies are intentionally empty here.
#
# Grouping rationale (per plan §Trait feature-gate strategy): names
# track storage primitives, not consumer APIs — primitives change
# slower than APIs, which keeps the cfg-gate topology stable.
