-
-Pure-Rust indexed BAM/CRAM/FASTA reader and pileup engine.
-
-## Why a custom implementation
-
-Cause we wanted to try it!
-This allows us to tweak the pieces that we want and to experiment with different approaches.
-
-Right now, we have:
-
-- Zero per-record allocation: `RecordStore` packs all variable-length data into contiguous byte slabs (names + data). No `Box`, no `Rc`.
-- Cluster-optimized I/O: `RegionBuf` bulk-reads all compressed bytes for a region in one operation, then decompresses from memory. Important for high-latency NFS/Lustre on HPC clusters.
-- Custom pileup engine: tailored access patterns with overlapping-pair dedup, per-position max-depth, and read filtering.
-- SIMD optimizations for x86_64 (SSSE3, AVX2) and aarch64
-- Only native dependency is `libdeflate`.
-
-## Architecture
-
-```mermaid
-flowchart TD
-    A[BAM file] --> B[RegionBuf\nbulk read into RAM]
-    B --> C[fetch_into]
-    C --> D[RecordStore\n3 contiguous Vecs, zero per-record alloc]
-    D --> E[PileupEngine\nIterator of PileupColumn]
-    E --> F["PileupColumn { pos, Vec<PileupAlignment { base, qual, strand, … }> }"]
-```
-
-## Specs
-
-Requirements live in `docs/spec/*.md` using [Tracey](https://tracey.bearcove.eu/) `r[rule.id]` syntax. Implementations are annotated `// r[impl rule.id]`, tests `// r[verify rule.id]`.
-
-## Testing
-
-```sh
-cargo test
-```
-
-Comparison tests in `tests/` validate against `rust-htslib`. Property tests use `proptest`.
