Consolidates partition logic, metadata storage, and layer management directly into KmerIndex. Renames obikpartitionner to obikpartition, retaining only PartitionRouter for superkmer routing. Removes intermediate .partition() accessors in favor of direct methods on the index and updates PartitionCache::build to accept &KmerIndex directly. Derives n_partitions from config.n_bits and consolidates k-mer/minimizer sizes into IndexMeta.config. Fixes a regression where PartitionRouter::open incorrectly defaulted to closed.
Update Cargo manifests, dependency paths, and Rust imports across the workspace to reflect the `obikpartitionner` to `obikpartition` rename. Synchronize architecture and implementation documentation with the new module structure. Fix minor syntax issues in test assertions to ensure compilation compatibility. No behavioral or API changes are introduced.
Rename the KmerPartition type to KmerPartitions across obikindex, obikpartitionner, and obikphylo/siblings to reflect an updated data model. Update the Mat enum in siblings/cache.rs to add a SparsePresence variant and simplify opening logic by delegating sparse versus dense detection to PersistentBitMatrix. Apply consistent code formatting, import reordering, and multi-line refactoring throughout the affected modules.
Replaced scattered direct metadata loading with centralized instance methods on `KmerPartition` to guarantee consistent error mapping and legacy recovery. Introduced `StorageKind`, `LayerContent`, and `EvidenceKind` enums alongside lightweight disk-probe methods that inspect file presence without opening heavy data structures. Updated callers across the index, partitioner, and phylo modules to use the new partition API, and added unit tests validating the introspection behavior.
Introduce a design specification outlining performance bottlenecks in layer data access and an agreed-upon implementation direction for caching. Refactor the codebase to centralize index and layer directory path resolution within the partition object, replacing manual string joining and external helper functions with dedicated accessor methods.
