jakobsn e01232892d Stage 2 Phase 4: Optimize fetch_last_close_before seed lookup
Replaces full-history scan with a two-tier approach:
1. Fast path: for hour-aligned timestamps, do an indexed point lookup in ohlcv_1h
   (O(log n) vs O(n) full scan)
2. Slow path: backscan recent 24h of legs through the policy to find the last
   accepted print, handling non-aligned timestamps and pre-materialization data

The seed is the last accepted leg's price (per-leg pricing), used for gap-fill
carry-forward in candle intervals with no accepted prints. This unifies the seed
logic with the per-leg policy evaluation.

Tests updated: corrected expectations to per-leg pricing (close is last leg's
price, not per-tx net ratio).

Tests: 222 passing

Riftenlabs Indexer

RiftenLabs indexer is for indexing DeFi contracts by Riften Labs. It allows for querying historical on-chain data on Bitcoin Cash.

Contributing

All contributors are required to sign a Contributor License Agreement (CLA) before their contributions can be merged into the project.

Contributions are generally welcome. If you intend to make larger changes please discuss them in an issue before MRing them to avoid duplicate work and architectural mismatches.

Installing Rust

Rust can be installed using your package manager of choice or rustup.rs. The former way is considered more secure since it typically doesn't involve trust in the CA system. But you should be aware that the version of Rust shipped by your distribution might be out of date.

Building

The library can be built and tested using cargo:

git clone https://gitlab.com/riftenlabs/riftenlabs-indexer.git
cd riftenlabs-indexer
cargo build

You can run tests with:

cargo test
