Define a shared Algorithm trait with an associated Output type and a parameterless run(&mut self) method. Refactor PartitionRouter, Dereplicator, Counter, and LayerBuilder to implement the trait, standardizing receivers to &mut self and moving configuration and progress callbacks to dedicated builder setters. Decouple error handling using a generic boxed error type and update workspace dependencies accordingly.
The command now supports reopening existing indexes instead of failing when the output file exists. Control flow branches between opening an existing index and constructing a new one, moving configuration setup exclusively to the creation path. Directory existence is enforced upfront with proper I/O error propagation. The --force flag retains its original semantics by removing the target directory before proceeding with a fresh build.
Move partition dereplication logic into a dedicated `obikderep` crate that implements a two-phase hash-split/merge strategy with Rayon for parallel processing. Centralize superkmer file path construction in `obilayeredmap` and update dependent crates to use the new pipeline and shared path helpers. Adjust test suites to explicitly invoke the dereplication step.
Update all dependent crates and internal imports to reference the renamed module. Expose configuration parameters and genome metadata through new public accessor methods in the index API, and update documentation comments to align with the new package name.
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.
Bumps core dependencies including ndarray, rand, hashbrown, niffler, ureq, sysinfo, indicatif, lru, and remove_dir_all. Adapts source code to accommodate breaking changes by migrating RNG initialization, adjusting HTTP response handling, and replacing the fs4 crate with standard library file locking. Adds a planning document for query benchmarking and sparse index regression tests.
Explicitly sets `default-features = false` for the `obikindex` dependency to ensure no default features are activated during dependency resolution and compilation.
Introduces `--subsample N` and `--shannon` CLI flags to cap retained variable families via proportional reservoir sampling and compute per-family Shannon entropy. Updates the family scanning API to support explicit selection filtering with early-exit optimization, resolving an indexing drift issue in monomorphic layers. Streams entropy metrics for 15-state and 4-nucleotide spaces directly to CSV while maintaining parallel processing across sibling layers.
Relocates `SiblingAnnex`, `FamilyMask`, and `SiblingAnnexBuilder` from `obicompactvec` to the local `obikphylo::siblings` module. Replaces the previous implementation with a memory-mapped version using `memmap2`, featuring a 2-byte-per-slot layout, explicit bitfield manipulation, and support for concurrent atomic writes. Updates all sibling module imports to local paths and adds the `memmap2` dependency to `obikphylo`.
Relocate the `siblings` and `cardcomp` modules from `obikindex` to a dedicated `obikphylo` workspace member. Convert inherent methods on `KmerIndex` into extension traits, update import paths across `obikmer`, and add supporting accessor methods to `obikseq` and `obilayeredmap`. This restructuring reduces the public API surface of `obikindex` while organizing phylogenetic iteration, caching, and distance calculation logic under a dedicated crate.
