Introduces the `--findere-z` CLI flag to override the index's sliding window parameter and implements `apply_findere` to filter k-mer hits using a z-consecutive positions window. Adds structural support for `--detail` mode, including per-sequence k-mer offsets, conditional allocation of per-position coverage vectors, and JSON serialization. Updates architecture documentation, CLI references, and annotation schemas to align with the new implementation, resolving prior discrepancies with `--detail` and `--mismatch` flags.
Refactor `Kmer`, `SuperKmer`, and chunk reader into optimized, generic representations with compile-time length parameters and bitwise operations. Update the pipeline and scheduler to support batch processing, 1→N flat transformations, and multi-source merging. Introduce an approximate evidence mode using b-bit fingerprints and `.idx` files, alongside existing exact mode. Update CLI documentation, minimizer selection, and query output schema accordingly.
Restructure architecture documentation to reflect the decoupled `MphfLayer` design wrapped by `LayeredStore<S>` and enforce strict multi-genome column invariants. Introduce the approximate index architecture, replacing exact `evidence.bin` with compact `fingerprint.bin` using B-bit fingerprints and z-consecutive k-mer matching. Update CLI flags, add `reindex`/`estimate` workflows, and refactor APIs to support separate exact/approximate evidence handling. Finally, provide a comprehensive on-disk layout specification, including the pipeline state machine, JSON schemas, binary formats, and refined Strategy B unitig evidence details.
These files catalog test coverage for Rust modules across architecture, implementation, and theory sections. They track recent structural changes, flag areas prone to documentation drift, and mandate verification of key parameters and routing logic to maintain alignment with the active codebase.
This change introduces the `query` CLI command and its supporting infrastructure for sequence-to-genome mapping and k-mer matching. It adds a `QueryLayer` abstraction backed by MPHF and persistent matrices, exposes the index partition for direct querying, and implements `Hash`/`Eq` for `RoutableSuperKmer`. The command ingests sequence batches, deduplicates superkmers, routes them to index partitions for parallel exact or 1-mismatch matching, and outputs results as FASTA records annotated with JSON metadata. Includes `serde_json` dependency addition, module exports, and documentation updates.
Introduces a new `merge` CLI subcommand and underlying implementation to consolidate multiple pre-indexed k-mer indexes into a single output. Adds `append_column` methods to persistent bit and int matrices to enable incremental genome column expansion without rebuilding the MPHF. Includes new error variants for index readiness and configuration mismatches, adds a `--force` flag to the index command, and updates documentation and navigation structure accordingly.
Introduces ColumnWeights, CountPartials, and BitPartials traits to compute and finalize partial distance matrices. Implements these traits for PersistentBitMatrix, PersistentCompactIntMatrix, and a new LayeredStore<S> wrapper that aggregates metrics across layers via parallel reduction. Adds ndarray for numerical aggregation and updates architecture documentation to reflect the trait-driven design and pending refactoring roadmap.
Add comprehensive documentation for the `obilayeredmap` crate, `PersistentCompactIntVec`, `PersistentBitVec`, and the hierarchical k-mer index architecture, including sidebar navigation updates across all documentation pages. Refactor the Bray-Curtis distance computation in `obicompactvec` to decouple numerator and denominator calculations, replacing direct pairwise calls with explicit loops over precomputed sums. Update tests to verify column sum accuracy and align with the simplified API.
Introduces `partial_jaccard_dist` to return raw intersection and union counts, improving Jaccard distance flexibility. Corrects `not()` to explicitly zero padding bits in the final word, ensuring accurate bit-counting for partially-filled words. Adds an optimized `build_from_counts` constructor.
