`review` scanned the whole grouped BAM and wrote every read whose MI matched an extracted consensus molecule, so `<output>.grouped.bam` also held mates and other reads of the molecule that overlap no variant. fgbio's ReviewConsensusVariants writes `groupedIn.query(variants).filter(rec => sources.contains(toMi(rec)))`: only grouped reads that overlap a variant locus. Both extractions now share one helper that issues a single multi-interval indexed query (one point region per variant) and differ only in the per-read filter; the grouped filter keeps a read when its MI base is in the review set. As in fgbio, `toMi` is applied to every variant-overlapping grouped read, so a missing MI is now an error (fgbio's "<name> did not have a value for tag MI", plus a hint and the BAM being read) instead of a silent skip. `to_mi` borrows the MI, so the per-read checks do not allocate. The output BAMs are staged beside their destinations and renamed into place only after both are complete, so a failed run leaves no truncated BAM. Each BGZF writer is finished by value, so a failed final flush is an error and each BAM ends with one EOF block, not two. The review file skips unmapped reads in its consensus counts, rows and raw counts, as fgbio's SamLocusIterator does, so a placed unmapped read that keeps a CIGAR is no longer counted. fgumi-raw-bam's query overlap now follows htsjdk's compareIntervalToRecord in one shared span rule: an unmapped read placed at a position covers only that base whatever its CIGAR, and a mapped read with a zero-length reference span ends at start - 1, so it never matches a point query. Ports ReviewConsensusVariantsTest.scala:227 with fgbio's full fixture and exact read sets. Adds tests for MI-less grouped reads on and off a variant, no outputs after a failure, a single EOF block, placed unmapped reads with a CIGAR (query and review file), a mapped zero-span read at a variant, a multi-variant grouped read written once, and raw-bam footprint tables. Changes output for: `review` `<output>.grouped.bam` (no longer contains mates or other reads of a reviewed molecule that overlap no variant site, nor mapped zero-reference-span reads); `review` `<output>.txt` (consensus and raw base counts and rows no longer include unmapped reads placed at a variant that carry a CIGAR); `review` now errors on a variant-overlapping grouped read with no MI tag and then leaves no output BAMs.

Summary
fgumi reviewread the whole grouped BAM in sequence and wrote every read whose MI matched an extracted consensus molecule. As a result<output>.grouped.bamalso held the mates and other reads of each reviewed molecule that overlap no variant site. fgbio writes only grouped reads that overlap a variant locus.The grouped extraction now makes the same single multi-interval indexed query as the consensus extraction, with one single-base region per variant. Both extractions share one helper (
extract_variant_reads) that owns the query, the header and the writer, and differ only in the per-read filter. A grouped read is kept when its MI base is in the review set. A read that overlaps several variants is still written once, and the output stays in coordinate order.As in fgbio, the MI lookup (
to_mi) runs on every grouped read that overlaps a variant. A missing MI on such a read is now an error rather than a silent skip; the message starts with fgbio's (<name> did not have a value for tag MI), adds what writes the tag, and names the BAM being read. MI-less reads that overlap no variant are never inspected.to_minow borrows the MI from the record, so the per-read checks do not allocate. The--helptext describes the narrower read set and the MI requirement.Both output BAMs are written to a staging file beside the output and renamed into place only after both are complete, so a failed run (e.g. the missing-MI error) leaves no truncated BAM at either output path, and a previous run's outputs stay intact. The renames and index writes that follow are not atomic as a set, so a failure there (e.g. a full disk) can leave a new BAM beside an older run's grouped BAM or index. Each BGZF writer is finished by value, so a failed final flush is an error and each BAM ends with exactly one EOF block (finishing with
try_finishlet the writer'sDropappend a second).The review file now skips unmapped reads in its consensus counts, consensus rows and raw counts, as fgbio's
SamLocusIteratordoes (htsjdkAbstractLocusIteratorskips every read flagged unmapped). Before, an unmapped read placed at the variant that still carried a CIGAR was counted and could get its own row.fgumi-raw-bam's indexed query now uses htsjdk's overlap footprint (BAMQueryMultipleIntervalsIteratorFilter.compareIntervalToRecord) in both the single- and multi-interval paths, which now share one span rule:start - 1, so it never matches a point query (previously one base at its start, as in htslib).Changes output for:
review<output>.grouped.bam, which no longer contains mates or other reads of a reviewed molecule that overlap no variant site, nor mapped zero-reference-span reads at a variant.review<output>.txtconsensus and raw base counts and rows no longer include unmapped reads placed at a variant that carry a CIGAR.reviewnow errors on a variant-overlapping grouped read with no MI tag, and leaves no output BAMs when it fails. Benchmark baselines for the review grouped output need re-blessing.fgbio parity (e51a661)
ReviewConsensusVariants.scala:206:groupedOut ++= groupedIn.query(variants).filter(rec => sources.contains(toMi(rec))). fgumi now uses the same read set and the same per-read MI check.ReviewConsensusVariants.scala:88:toMithrowsIllegalStateException(s"${r.name} did not have a value for tag MI"). fgumi's message starts with the same text.BAMQueryMultipleIntervalsIteratorFilter.compareIntervalToRecord:alignmentEnd = getAlignmentStart()for an unmapped read with a position, otherwisegetAlignmentEnd()(start + cigar.getReferenceLength() - 1). fgumi's query footprint now matches both cases. A placed unmapped read is written only if it sits on a variant and has a reviewed MI.ReviewConsensusVariants.scala:231-255builds the review file fromSamLocusIterator; htsjdkAbstractLocusIterator.java:283skipsgetReadUnmappedFlag()reads. fgumi's review-file loops now skip them too.ReviewConsensusVariantsTest.scala:227("extract the right reads given a set of loci") expectsA1/1, A2/1, B1/1, D1/1, E1/1, F1/1, H1/1, H1/2in the grouped output. Before this change fgumi also wrote the off-locus matesA1/2, A2/2, B1/2, D1/2, E1/2, F1/2.Tests
test_review_grouped_bam_contains_only_reads_overlapping_variants: an exact port of fgbio:227. It uses fgbio's full fixture, including theGpair (overlaps chr1:30 but is reference there) and the unmappedX1/Xpairs. It asserts the exact sorted grouped, consensus and review-file read sets. It replacestest_extracts_correct_reads_for_variants, a weaker port of the same test that only checked that some names were present.test_review_errors_on_variant_overlapping_grouped_read_without_mi: an MI-less grouped read on the variant fails with the exact full error chain. The test calls the grouped extraction directly as well asexecute, because the review-file stage raises the same message for the same read.test_review_failure_leaves_no_output_bams: after that failure the output directory holds exactly the files it held before (no.consensus.bam,.grouped.bamor staging file).test_review_output_bams_end_with_one_eof_block: each output BAM ends with exactly one 28-byte BGZF EOF block.test_review_file_skips_placed_unmapped_reads_with_a_cigar: unmapped consensus and grouped reads placed at the variant with a 10M CIGAR get no row and are not counted; the grouped one is still written to.grouped.bam.test_review_skips_mapped_zero_span_grouped_read_at_a_variant: an MI-less mapped10Sgrouped read at the variant is neither inspected nor written.test_rev3_05_multi_locus_read_written_oncenow also asserts that a grouped read overlapping two variants is written to.grouped.bamonce.test_review_ignores_grouped_read_without_mi_that_overlaps_no_variant: an MI-less read off every locus causes no error and is not written.test_review_grouped_bam_includes_placed_unmapped_mate_only_at_a_variant: an unmapped mate placed on the variant is written, and one placed off it is not, even though the off-locus mate carries a 10M CIGAR that would reach the variant.fgumi-raw-bam:record_span_1based_follows_htsjdk_footprintandintersects_region_follows_htsjdk_footprint(rstest tables over mapped, zero-span and placed-unmapped records), andquery_paths_follow_htsjdk_footprint(both indexed query paths over a real indexed BAM).Mutation-checked:

generate_review_filealready required it, so no valid run is affected, but a missing grouped index now fails before.grouped.bamis written.generate_review_filestill counts raw bases by querying the input grouped BAM, not the review output as fgbio does.

cargo ci-fmt,cargo ci-lint,cargo ci-doc,cargo ci-tag-literals,cargo nextest run --workspace(10543 passed, 31 skipped).Risk:
fgumi reviewchanges grouped-BAM and review-file output, pinned by tests for variant-overlap selection, MI filtering, coordinate order, and unmapped-read handling; unsafe changes: none identified, with no CLAUDE.md allowlist update indicated; memory bounds, queue capacity, and thread/backpressure policy: none indicated.Fix:
fgumi reviewnow selects grouped reads that overlap variant loci and whose MI matches a retained consensus read. It writes reads that overlap multiple loci once, in coordinate order. A grouped read without MI causes an error only when it overlaps a variant.Review-file counts and rows now exclude unmapped reads. Indexed BAM queries use htsjdk-compatible overlap rules for placed-unmapped and zero-reference-span reads. The command stages both BAM outputs before installing them.
The supplied objectives report passing formatting, lint, documentation, tag-literal, and workspace test checks (10,543 passed; 31 skipped). Benchmark baselines for the narrower grouped BAM need re-blessing.
