fix(sv): stop a filtered Manta record from hiding a real deletion, and read chrX depth by sex by geiresx · Pull Request #50 · geiresx/OwnGenome

Summary by CodeRabbit

Bug Fixes
- Delly read-depth support now accounts for sample sex and pseudoautosomal regions when assessing sex-chromosome calls.
- Filtered or reference/no-call Manta records no longer suppress overlapping Delly or CNVpytor calls. Delly records with reference or no-call genotypes also no longer suppress CNVpytor calls or qualify as added calls.
- VCFs with multiple sample columns are rejected with an error identifying the samples.
- Rechecks now detect changes to pinned image digests and handle missing run information and invalid release data more clearly.
Reliability
- Pipeline runs wait for an active ClinVar refresh to finish before proceeding.
Documentation
- Clarified call coverage rules, sample requirements, and sex-aware read-depth expectations.

…the PARs The class 4-5 postfilter read a Delly RDCN on chrX and chrY as if the sex were unknown, so a male's chrX deletion with RDCN 1 and a female's chrX duplication with RDCN 2 counted as depth-supported, and a duplication inside the PARs needed only 2 copies. Step 05 and ANNOTSV now pass --sex and --par-bed to annotsv_postfilter.py, which applies the rule cnvpytor_to_vcf.py already uses when it adds a Delly call. Bead: pgp-5bja.24

The reports read the genotype and phase of the first sample column of AnnotSV's input, so a multi-sample SV_VCF let another person's genotype, or a 0/0, decide whether a deletion counts. sv_svlen_fix.py, the first pass of both step 05 and ANNOTSV, now exits 2 and names the samples. Bead: pgp-5bja.24

…t out, never crash on a bad header An image re-pinned to a new digest at the same tag compared equal, because the check reduced every image to its tag; it now compares the full reference. A pin with no upstream lookup that the run's manifest lacks is now "unknown" instead of "no-newer-release". A pin read only by steps run-all.sh recorded as skipped is left out. A malformed Last-Modified of a PGS file and an offline release with no tag are now errors of that lookup, not a crash. --refresh-clinvar now holds GENOME_DIR/clinvar/.refresh.lock exclusive while setup.sh refreshes; run-all.sh and step 06 hold it shared, so a run that starts during a refresh waits for it. Bead: pgp-5bja.23 Bead: pgp-ax3g

NF_WEBLOG_PLUGIN in scripts/run-all.sh had no Renovate manager, so no bot saw a new nf-weblog release. The rule also moves the copy in docs/live-site.md. Bead: pgp-5bja.23

A Delly RDCN of 1000000 was formatted as 1e+06, which the shared rule reads as no estimate. Adds chrY, PAR deletion and PAR-boundary cases. Bead: pgp-5bja.24

…Vpytor call A Manta DEL or DUP that Manta filtered (MinGQ and the rest) or genotyped 0/0 or ./. went into the overlap index, so it dropped the Delly PASS or CNVpytor deletion it overlapped, and the summary later skips the 0/0 record: the real deletion was lost. Index only base records with FILTER PASS or . and an allele other than 0; a sites-only base still covers.

…planned run-all.sh writes no status row for an opt-in step 50-53 left out of TOOLS, so the check saw it as 'not planned', not 'skipped', and still called its changed pin rerun-ready. Count both states, and leave nothing out when the status file records no step at all.

Walkthrough

Step 05 now evaluates Delly read-depth support using sample sex and PAR intervals. Base calls suppress overlapping calls only when they meet FILTER and genotype criteria. The SV length fixer rejects VCFs with multiple sample columns.

Changes: Sex-aware Delly depth support

Layer / File(s)	Summary
Pass sex and PAR context into depth evaluation `bin/annotsv_postfilter.py`, `modules/local/annotsv/main.nf`, `scripts/05-annotsv.sh`, `docs/05-annotsv.md`, `tests/test_annotsv_postfilter.py`	The postfilter passes sex and PAR intervals to the shared Delly depth rule. The documentation and tests cover sex-specific thresholds and PAR boundaries.

Base-call coverage filtering

Layer / File(s)	Summary
Check base-call eligibility before indexing `bin/cnvpytor_to_vcf.py`, `docs/05-annotsv.md`, `tests/test_annotsv_sv_inputs.py`	Filtered records and records with only reference or missing alleles no longer cover overlapping calls. Sites-only base records still cover calls.

Single-sample VCF input

Layer / File(s)	Summary
Reject multi-sample VCF headers `bin/sv_svlen_fix.py`, `docs/05-annotsv.md`, `tests/test_annotsv_sv_inputs.py`	The script exits with status 2 and reports sample names when the VCF header contains multiple sample columns.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to 6e664

Two bounded issues remain. A Delly deletion could be wrongly hidden when only the first sample of a multi-sample base VCF fails its filter. A standalone ClinVar screen or pipeline run could read while a refresh replaces files if the lock file is inaccessible. Both are narrow cases that can be addressed in follow-up or before merge.

Security architecture risk: Low · up to 6e664

The reviewed changes improve variant qualification and add coordination around shared ClinVar files. No introduced attack path was established. However, locking does not cover every supported entrypoint, interrupted cache publication remains nontransactional, and deployed access policies were not available.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — ClinVar consistency failures can affect every sample consuming the same GENOME_DIR cache, rather than remaining isolated to one sample. The lock therefore coordinates a cross-sample resource, not a tenant authorization boundary.

Security Findings and Attack Paths

observed — Full image references newly enter the downloadable recheck state. The existing live-site plugin already permits that file, and browser dispatch retains its existing session requirement when a password is configured. The checked default references identify published images; deployment-specific reference sensitivity remains unestablished.

Trust Boundaries and Controls

observed — ClinVar locking is advisory and participation-dependent. Shell readers skip locking when flock or a readable lock is unavailable. Direct setup refresh and bare Nextflow execution explicitly take no lock, so the new protocol is not universal cache protection.

Hardening Proposals

proposed — If generation-wide consistency is required across all supported entrypoints, centralize lock participation at the shared updater and consumers, and consider immutable cache generations with atomic publication. This would address existing bypass and partial-publication limitations rather than remediate an established new vulnerability.

Full details: Title check

Explanation

The title names two changes: a filtered Manta record no longer hides a real deletion, and chrX depth is read by sex. The raw summary covers both. The cnvpytor_to_vcf.py and test changes implement the Manta coverage fix, and the annotsv_postfilter.py, main.nf, and run-all changes implement the sex-aware chrX/Delly RDCN depth check. The title does not mention the other changes (ClinVar lock, owngenome_recheck, renovate, sv_svlen_fix single-sample check), but it does not need to cover every detail. The title is specific and matches the primary changes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 34.48% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 29 functions across 10 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Handle missing PAR intervals when male sex is supplied.

Without --par-bed, --sex male treats every chrX position as outside the PAR. A PAR deletion with RDCN 1 can therefore be downgraded from class 4 or 5 to class 3. Handle missing PAR status without assuming the position is outside the PAR.

Check the first sample’s filter before indexing its call.

For a multi-sample base passed directly to cnvpytor_to_vcf.py, another sample can pass while the first sample has FT=MinGQ. A PASS record with first-sample GT=0/1 can then suppress an overlapping Delly deletion. Check the first sample’s FT when present, while preserving support for records without FT.

A Delly PASS deletion genotyped 0/0 or ./. was added to the AnnotSV input and then covered the CNVpytor deletion at the same place, which the summary lost when it skipped the 0/0 record. Delly calls now need a non-reference allele too, the same rule the Manta base follows.

Stop if the ClinVar lock is inaccessible.

If a standalone screen can read ClinVar data but cannot read .refresh.lock, this check silently proceeds without a shared lock. A privileged refresh can then replace the data and indexes while the screen reads them; the refresh's active-run check does not cover a standalone screen. Make lock creation or acquisition fail with a clear error when flock is available. Apply the same correction to scripts/run-all.sh at Lines 71–75. (raw.githubusercontent.com)
