Codecov flagged lines 86-102 in crates/wickra-core/src/ohlcv.rs as missed
(file at 90.00%) — the entire body of `Candle::new_unchecked`. Every
existing test routes through the validating `Candle::new`, so the unchecked
constructor (intended for callers like the aggregator and parsed-payload
paths that have already validated upstream) was dead.
Add candle_new_unchecked_preserves_fields_verbatim:
- first assertion builds a candle with six distinct field values and
verifies each reads back exactly.
- second assertion feeds an OHLC combination (high < low) that the
checked constructor rejects with Error::InvalidCandle, then proves
Candle::new_unchecked still builds the struct as-is. This documents
and enforces the API contract that the unchecked variant performs
no validation.
ohlcv.rs is now at 170/170 lines, no behavioural change.
