It runs the representative + positive and negative VNtyper FASTQ fixtures through `kestrel-rs` + directly and compares VCF records with the Java-generated expected VCFs. + Reduced 2026-05-14 on branch `fix/vntyper-fastq-parity`: the original + port missed Java's active-region right-scan peak/valley fallback for + repetitive profiles. The new regression + `active_region_detector_splits_repetitive_peaks_at_last_stable_valley` + covers the VNtyper `N-S`-like profile that used to merge two Java regions + into one Rust region. After the active-region fix, the opt-in vendor gate + still failed with `positive` at 1780 Rust records vs 3737 expected Java + records and `negative` at 1911 Rust records vs 4897 expected Java records. + After saved-state deduplication, the current gate still fails but improves + to `positive` at 1804 Rust records vs 3737 expected Java records and + `negative` at 2217 Rust records vs 4897 expected Java records. + A single-reference `N-S` comparison now points at remaining + haplotype/state traversal differences: Java emits seven haplotypes at + bounded `2/2` settings while Rust emits four, missing the Java low-depth + and insertion branches. Java's runner also appears to reset effective + aligner/haplotype caps to builder defaults by calling + `setMaxRepeatCount` after `setMaxAlignerState` and `setMaxHaplotypes`; + forcing Rust to use those effective defaults made the reduced `N-S` case + exceed ten minutes, so the next fix has both semantic and performance + dimensions. A smaller Rust probe with `--maxalignstates 4 + --maxhapstates 15` also exceeded five minutes on the single-reference + `N-S` case before saved-state deduplication. After deduplication, the + `4/15` probe completes and recovers the Java low-depth branch at + `N-S:85`, but still misses the Java insertion branch at `N-S:86` and + emits extra first-region low-depth branches. The Java-effective `10/15` + probe still exceeded ten minutes and was stopped. A narrower attempt to + save repeated candidate branch states without following them also + exceeded five minutes on the reduced `N-S` `4/15` probe and was not kept. + Note: upstream Java VNtyper config uses `max_align_states=40` and + `max_hap_states=40`. The current native BioScript parity gate uses the + bounded native settings `max_haplotypes=2` and `max_saved_states=2`. + A one-off native FASTQ run with `40/40` was stopped after exceeding five + minutes without output, so full upstream-parameter parity is also a + `kestrel-rs` performance/parity task. +- [x] `bcftools-rs`: confirm the VNtyper-required sort/compress/index path is + complete for all generated VCFs. + Confirmed for tiny Kestrel-generated VCFs in + `rust/bioscript-libs/tests/vntyper_facades.rs` and existing BCFtools + adapter tests.
