Codecov flagged 30 uncovered lines in crates/wickra-core/src/traits.rs (file at
75.60%): the const borrow accessors Chain::first / Chain::second (140-147), the
Chain::warmup_period + Chain::name Indicator-impl bodies (167-178), the full
Identity test-helper Indicator surface — reset, warmup_period, is_ready, name
(198-209), and Doubler's warmup_period + name (228-236).
None of the existing tests touched those code paths: every chain test invoked
update/reset/is_ready through the Chain wrapper without ever inspecting the
borrow accessors, querying chain.warmup_period(), or asking for chain.name(),
and the Identity helper was only ever driven by batch (which calls update
only). Doubler's warmup_period and name were similarly dead because
Chain::warmup_period and Chain::name themselves were dead.
Add two new tests at the end of the Chain section in mod tests, immediately
before the parallel-feature-gated test:
- chain_accessors_and_metadata exercises chain.first(), chain.second(),
chain.warmup_period(), chain.name(), and pulls Doubler::warmup_period
+ Doubler::name in via the borrowed accessors.
- identity_helper_full_indicator_surface asserts warmup_period == 0,
name == "Identity", and walks is_ready through both seen=false and
seen=true via an update/reset cycle.
traits.rs is now at 123/123 lines, no behavioural change.
