Run Adhoc Cases

Run a strategy against the curated case-study set for one asset.

Companion endpoint to /robustness/quick: while /quick produces the Layer-2 regime-ensemble robustness score (synthetic), this endpoint produces the Layer-1 + Layer-3 case studies (empirical anchors plus targeted synthetic stress probes).

Designed for parallel-call from the mainpage so that score and cases arrive independently. Synthetic cases without pre-computed replicas (e.g. WHIPSAW pending) are skipped and reflected in n_skipped.

Args: replica_limit: optional cap on synthetic replicas per case (default: 50, i.e. full cache). Set e.g. 30 for faster Mainpage runs.
