- Delete back-compat shims data_provider.py / oanda_provider.py;
test_all.py now imports providers.* directly (ForexDataProvider name
retired; the two shim-only tests removed, 268 -> 266 tests)
- Delete backtest/research/calendar_store.py (no importer, no entry
point); config.py audit comment reworded
- Delete executed plan doc (2026-07-21 centralized-config) and the two
unbuildable guide PDFs; HTML guides remain the source of truth
- OANDA_MIGRATION_ROADMAP.md status header corrected: phases 1-2
shipped 2026-07-28, feed is live on Oanda; phases 3-6 still unbuilt
- Branches deleted locally + on both remotes: oanda_demo (merged),
web-dashboard, eurusd-modular, reversal-exit-alert (owner-approved
permanent deletion); July stash dropped

Approved 2026-07-24: 6-phase plan for fully switching the signal feed
from Twelve Data to Oanda v20 (inert plumbing -> backtester agnosticism
-> pricing-stream monitor -> shadow parity -> book re-validation with
owner cost gates -> reversible cutover). TD remains a permanent
fallback. Grounded in the 2026-07-24 divergence study (10% bar-direction
flips, 11%-of-ATR noise, real Oanda spread ~$0.72 vs assumed $0.30).
