mathiasandClaude Sonnet 4.6 bd8962f997 feat(multipair): G10 multi-pair pipeline + USE_MULTIPAIR knob (Option C) 
- prepare_hourly.py: parameterize PAIR env var; OUT_DEFAULT per-pair; load_m1_from_zips(pair=)
- prepare_multipair.py: inner-join 5-pair hourly parquets on datetime → wide parquet
  cols: datetime, {pair}_ret, {pair}_rv × n_pairs; eurusd_rv = target
- fetch_multipair.py: download GBPUSD/USDJPY/USDCHF/AUDUSD M1 2008-2023 from histdata
- train.py: USE_MULTIPAIR knob (JEPA_USE_MULTIPAIR=1); build() reads multipair parquet
  with n_channels = n_pairs × 2; target = eurusd_rv
- Taskfile: data:fetch:multipair, data:prepare:pair, data:prepare:multipair, data:test updated
- 7 new tests in test_multipair.py; 34/35 pass (1 SKIP until multipair parquet built)

mathiasandClaude Sonnet 4.6 caccd1aa7b feat(features): add hl_range + ret_intrabar OHLCV features (4-channel input) 
- prepare_hourly.py: keep O/H/L columns from M1 zips; compute per-hour
  hl_range=log(H/L) and ret_intrabar=log(close/open); backward-compat
  (falls back to 4-col output only when O/H/L present in input)
- train.py build(): auto-detect extra features from parquet columns
  (FEAT_COLS = [ret, realized_vol] + [hl_range, ret_intrabar] if present)
- 5 new tests (9 total in test_prepare_hourly); 24/24 pass

mathiasandClaude Sonnet 4.6 e31905dc43 feat(data): EUR/USD hourly pipeline + 2008-2023 M1 dataset (#2)
CD / Lint / Test / Vet (push) Successful in 4s
Details
CD / Build & Import (push) Failing after 8s
Details
CD / Deploy via GitOps (push) Has been skipped
Details 
- scripts/prepare_hourly.py: M1→hourly aggregation (realized_vol = sqrt(Σr²),
  MIN_BARS=30 threshold, no weekend rows, year-based split preserved)
- tests/test_prepare_hourly.py: 5 TDD tests, all green
- train.py: USE_HOURLY=True, WINDOW=240 (10-day), PATCH_LEN=24 (1-day patches);
  build() prefers eurusd_hourly.parquet, falls back to daily; EXPORT BLOCK updated
- Taskfile.yml: data:fetch:historical, data:prepare:hourly, data:prepare:all, data:test
- 98,591 hourly rows (2008-2023) covering GFC, Euro crisis, Brexit, COVID, Fed cycle
