gahusb	8eefe9d79d	fix(signal_v2-phase3b): ChronosBolt predict_quantiles API support ... ChronosBoltPipeline.predict() does not accept `context` kwarg; it uses positional-only and is deterministic (no num_samples). Switch to predict_quantiles(context, prediction_length, quantile_levels) which returns (quantiles_tensor, mean_tensor). Implementation: if hasattr(pipeline, "predict_quantiles") → modern quantile branch. Else fall back to legacy sample-based predict (T5). Tests: switch to predict_quantiles mock returning (quantiles, None) with shape [1, 1, 3] for q10/q50/q90 directly. 45/45 tests pass.

gahusb	91de16675b	fix(signal_v2-phase3b): use BaseChronosPipeline for new model architectures ... ChronosPipeline (legacy T5) does not support amazon/chronos-2 or chronos-bolt-* (input_patch_size). Switch to BaseChronosPipeline which auto-detects variant and returns the appropriate sub-pipeline (ChronosBoltPipeline / Chronos2Pipeline / ChronosPipeline). Also handle the dtype kwarg deprecation: try newer `dtype=` first, fall back to `torch_dtype=` for older versions. Test mock_pipeline fixture updated to patch BaseChronosPipeline. 45/45 tests pass. Verified amazon/chronos-bolt-base loads on CUDA. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-17 08:57:22 +09:00
gahusb	28f9c8c3a6	feat(signal_v2-phase3b): chronos_predictor + 4 mock tests ... ChronosPredictor wraps HuggingFace ChronosPipeline. Batch predict returns ChronosPrediction(median, q10, q90, conf, as_of) per ticker. Confidence = 1 - clamp(spread/2, 0, 1) where spread = (q90-q10) / |median|. Lazy import of chronos lib (heavy). GPU auto-detect with FP16. 44 tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-16 18:00:46 +09:00
