Type Alias RpcReceiptToTxRequest

Block height near where receipt was created. Enables hint fallback scan on column miss. Anchor refreshes to each scan-resolved parent's exact execution height; later ancestors bounded via causality (emit before execute), so subsequent column-miss scans go Ancestor. Bump receipt_to_tx_max_hop_distance if cold archival gaps exceed default 20.

Cold-storage cost: per-row latency orders of magnitude over hot. To bound request cost:

• Supply block_height within parent's ±window (default 5).
• Supply shard_id. Omit → all-shards enumeration until walker crosses FromReceipt hop, multiplying cold-read cost.
• Don't widen window beyond indexer's accuracy; budget shared across full ancestry walk.

Receipt-id-only queries against periods with save_receipt_to_tx disabled stay unsupported: column never written, no self-locating.

Shard hint. Narrows scan to this shard at hint height. Omit to enumerate all tracked shards (higher cost). After walker crosses a receipt-origin hop, shard derived from parent's predecessor account and hint no longer applies. Best-effort across resharding: layout shifts can miss producer, walk returns UnknownReceipt.

Pre-first-scan width: ±window heights around hint. Caps at receipt_to_tx_max_hint_window (default 20). Ignored after first scan-resolved hop — walker switches to Ancestor mode at receipt_to_tx_max_hop_distance width.
