MSN Finance/Charts does not serve OHLCV data for XIDX stocks (returns 404).
Following the FP principle of not exposing capabilities a provider cannot fulfil:
- Remove impl HistoryProvider for MsnProvider entirely
- Remove fetch_charts from MsnClient
- Remove parse_chart_history, resample_history, trim_history_to_period from map.rs
- Remove MsnChart, ChartSeries, RawChart from raw_types.rs
- Remove parse_history_from_str, parse_close_only_history from parse.rs
- Decouple HistoryProvider from MarketDataProvider trait bound
- Add history_provider() factory: returns None for MSN, Some(Yahoo) for Yahoo
- CLI gates History/Technical on history_provider(), fails fast for MSN
- MSN mock returns Err(Unsupported); tests verify the behaviour explicitly
Add MsnProvider implementing MarketDataProvider trait with quote,
fundamentals, and history support. Includes provider-aware config
(file/env/CLI), cache namespace isolation per provider, symbol ID
mapping via embedded TSV, OHLCV resampling, and comprehensive unit
+ integration tests with MSN fixture data.
Key changes:
- MsnProvider with quote, key-ratios, and chart endpoints
- ProviderKind enum (yahoo/msn) with config hierarchy support
- Provider-namespaced cache buckets to prevent cross-provider poisoning
- Provider-aware MockProvider loading correct fixtures per provider
- Integration tests for config round-trip and cache isolation
