Summary: The experiment replay system (`MapDataReplayMetric`, `MapDataReplayRunner`, `replay_experiment`) is hardcoded for single-objective optimization, blocking multi-objective early stopping. `MapDataReplayMetric` conflates data serving with progression state, so multiple metrics cannot share a coherent timeline. This diff series extracts shared state into a `MapDataReplayState` coordinator. This diff (1/3) adds the `MapDataReplayState` class -- a shared state coordinator that manages normalized cursor-based progression across multiple metrics and trials. Uses a global min/max MAP_KEY to preserve cross-metric timing alignment. Serves original MAP_KEY values; downstream ESS normalizes independently via `_maybe_normalize_map_key`. Existing `MapDataReplayMetric` and helpers are unchanged in this diff. Differential Revision: D98741817
…layState (facebook#5138) Summary: The experiment replay system (`MapDataReplayMetric`, `MapDataReplayRunner`, `replay_experiment`) is hardcoded for single-objective optimization, blocking multi-objective early stopping. `MapDataReplayMetric` conflates data serving with progression state, so multiple metrics cannot share a coherent timeline. This diff series extracts shared state into a `MapDataReplayState` coordinator. This diff (2/3) rewrites `MapDataReplayMetric` and `MapDataReplayRunner` to delegate to the shared `MapDataReplayState` introduced in D98741817. Also updates `replay_experiment` and `estimate_hypothetical_early_stopping_savings` for multi-metric support: accepts `metrics: list[Metric]`, builds single-objective or multi-objective `OptimizationConfig`, extracts objective thresholds from the historical config, re-indexes non-contiguous trial indices, and deprecates `num_samples_per_curve`. Backward-compat `metric=` kwarg preserved for downstream callers (removed in D98741814). Differential Revision: D98741816
Summary: The experiment replay system (`MapDataReplayMetric`, `MapDataReplayRunner`, `replay_experiment`) is hardcoded for single-objective optimization, blocking multi-objective early stopping. This diff series extracts shared state into a `MapDataReplayState` coordinator. This diff (3/3) migrates all downstream consumers of `replay_experiment` and `estimate_hypothetical_early_stopping_savings` from the deprecated `metric=` (singular) kwarg to the new `metrics=` (list) API introduced in D98741816, and removes the backward-compat shim from `experiment_replay.py`.
