fix(cn): wire the copy-number intervals into the couple screen and the report, and close the review follow-ups - #8
Couple screening reports additional carrier-deletion alleles, including CFTRdele2,3 and two HBB deletions, using interval and CNVpytor data when available. Male AZF regions are also included.
Sample reports include interval copy-number results. AZFc estimates between whole copy counts are marked not assessed.
Interval data can provide a fallback source when other recognized copy-number tables are unavailable.
Documentation
Guidance covers interval results, overlapping HBB deletion rows, and CNVpytor disagreement reporting. Present-call disagreements are limited to intervals at least 2 kb long; missing CNVpytor calls are not shown for shorter alleles.
…een and the Nextflow report
Step 39 and COUPLE_CARRIER now hand couple_report.py each partner's
step 35 interval table and step 18 CNVpytor VCF when they exist, so the
carrier deletion alleles and AZF lines appear without a hand-run command.
HTML_REPORT places <id>_cn_intervals.tsv in paralogs/, where
collect_summary.py reads it, and main.nf joins it into the report inputs.
Bead: pgp-pfw6.36
HG002's DAZ depth gives an estimate of 3.63 in CI run 41767270253, so the
row is not assessed with reason between_counts. The case now checks that,
with the estimate held to 3.3 to 3.9, and checks that the same assertion
fails on the female table.
Bead: pgp-pfw6.36
…depth
Two interval rows at their HbVar GRCh38 spans (979 and 1035), checked by
placing the NG_000007.3 breakpoint flanks on NC_000011.10. The couple
screen lists both as carrier deletion alleles. The step 35 interval table
gains two lines; no existing row or column changes.
Bead: pgp-pfw6.36
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds two HBB deletion rows to the interval catalog, exposes interval tables to couple and HTML reporting, and updates couple reports to include the new alleles and CNVpytor disagreement checks. Tests and documentation cover the added rows and input paths.
The interval catalog adds the HBB 619 bp and Sicilian deletion rows. BAM analysis exposes interval results, and summary collection uses the interval table as a fallback when the SMN/catalog and HBA tables are unavailable. Tests cover the catalog rows, summary fallback, and the male AZFc between-count classification.
The couple report adds the two HBB deletion alleles. Present-state CNVpytor disagreement checks require an interval of at least 2,000 bp; the absent-state check is unchanged. The report and tests describe overlapping beta-globin rows and the resulting allele calls.
The couple workflow receives interval tables and CNVpytor VCFs. The HTML report routes interval tables to paralogs/. Step 39 and end-to-end tests cover input detection, report output, and behavior when inputs or wiring are absent.
The common HBB deletion target may reduce call confidence, and report and test-setup issues remain. Resolve or explicitly accept these risks before merging.
Security architecture risk: Low · up to 82912
The change makes sensitive genomic results available to additional reporting steps. The inspected paths preserve sample and partner association, and no introduced security weakness was established. Deployment access controls and complete downstream exposure remain outside the available evidence.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The demonstrated expansion is into existing per-sample and partner/family reporting outputs. Source-level routing retains those ownership scopes; the evidence does not establish deployment-level access restrictions or exposure of published reports.
Trust Boundaries and Controls
observed — Workflow sample IDs are validated before task execution. Couple routing filters metadata to selected member IDs, accepts only fixed suffixes with recognized ID prefixes, and passes explicit ID-to-path mappings. The consumer rejects IDs outside the pedigree and nonexistent input files. These controls counter the proposed cross-sample association and command-construction attack paths.
Resilience and Maintainability Implications
observed — The inspected consumers read staged inputs and derive output files; they do not mutate source genomic tables. Interval production uses a temporary file followed by replacement. Couple output files retain their pre-existing sequential write behavior, so this review does not assert transactional publication or interruption-safe recovery across the report set.

Enable the required shell error handling.
lib.sh sets -uo pipefail, so this case runs without -e. Guard the expected failures in the negative controls, then enable set -euo pipefail. This makes unexpected setup failures stop the case. (raw.githubusercontent.com)

Do not treat the AZFc bounding span as continuous target sequence.
AZFc_DAZ has four separated targets, but its interval row spans from DAZ1 through DAZ4. A CNVpytor deletion covering DAZ3 and DAZ4 can support a two-copy loss while covering less than half that bounding span. This check then reports that CNVpytor calls no deletion. (raw.githubusercontent.com)
Compare calls with the actual target segments, or report a partial overlap as inconclusive.

Keep the shared-risk line consistent with interval deletions.
The "No gene of the list where both partners carry a change." line counts only gene-level findings from screen_couple. Interval deletions in CN_ALLELES are reported in a separate section. When both partners carry a present HBB deletion, the report can state that no shared gene was found. The same report then lists both deletions as present. A reader may take the first statement as the screen's conclusion.
The split predates this PR for GJB6, CFTR, and HBB exon 3. This PR adds two more present-capable rows, so the same contradiction can now appear for HBB.
Adjust the shared-risk output so it does not say that no shared gene exists while interval deletions are present in both partners. For example, when any interval row is present for both partners, qualify the negative line:
Suggested fix
- section("Shared risk: both partners carry a change in the same gene", "shared",- "No gene of the list where both partners carry a change.")+ section("Shared risk: both partners carry a change in the same gene", "shared",+ "No gene of the list where both partners carry a change in the gene findings. "+ "See the carrier deletion alleles below for interval deletions.")

Enable fail-fast handling, while protecting expected failures.
The shell-script guideline applies to this file. Without -e, the unchecked fixture cleanup and creation commands can fail without recording a failure. A cleanup failure can leave stale fixture data, and no assertion checks that cleanup succeeded.
Add set -euo pipefail after sourcing lib.sh. Before enabling it, capture the expected report-noplace failure in nfrun; otherwise -e exits before NF_RC is assigned.
