Codecov flagged 13 uncovered lines in
crates/wickra-core/src/indicators/stochastic.rs (file at 93.43%):
- classic() convenience constructor (76-78) — every test passed
explicit (k_period, d_period) to new
- periods() const accessor (81-83) — never queried
- warmup_period (170-172), name (178-180) Indicator-impl bodies —
never queried
- line 208 (`50.0` literal) inside the test-only naive_k helper's
flat-range branch — k_matches_naive feeds an oscillating price
series, so the helper's range == 0 path was dead
Add classic_periods_and_metadata test asserting Stochastic::classic()
has periods (14, 3), warmup_period 16 (= 14 + 3 - 1) and name
"Stochastic". Extend flat_range_yields_k_50 to also call naive_k on
the flat candle series and verify the helper returns Some(50.0) for
every index ≥ k_period - 1 — exercises line 208 without diluting the
production-code assertion.
stochastic.rs is now at 198/198 lines, no behavioural change.
