Problem

The cDNA read checks of step 06 (CLINVAR_CDNA_CHECK) and step 17 (CPSR_CDNA_CHECK) only add a column to the report. Their tables reach the report through joins that keep a sample without them. Still, a failure in either check stopped the whole Nextflow run, because they were not in the report-only errorStrategy list in nextflow.config. One odd BAM or hit table could end a run before DeepVariant's results and the report.

Fix

  • nextflow.config: both checks join the report-only list. A task killed for memory or time is retried once, as before. Any other failure is ignored, named in failed_tasks.tsv, and run-all.sh marks the step failed. The report then shows the ClinVar and CPSR hits without the read check (bin/collect_summary.py reads the check table only when it exists).
  • The e2e-data-1 release now holds the pinned TRExplorer v2.1 catalog (TRExplorer.repeat_catalog_v2.1.hg38.1_to_1000bp_motifs.bed.gz, sha256 df9c23c4c66ae798759a00f1b042a255819dd95e6b5f2ac68b37e5072117642b, the TRX_SHA256 pin of scripts/ci/build-sv-rule-regions.sh). docs/testing.md says so. The runner already tries the mirror by file name first, so the catalogs fill no longer depends on the upstream release.

Outputs: no file, option or format changes.

Checked on main, no change needed

Guard check

  • scripts/ci/check-report-only.py finds each workflow process whose channels reach main.nf only through the report's remainder: true joins, and fails when no report-only withName block in nextflow.config names it. tests/test_contract_report_only.py runs it in Guard (every tests/test_*.py runs there) with planted controls: dropping CLINVAR_CDNA_CHECK, CPSR_CDNA_CHECK or the MITO_DELETIONS block must fail and name the process.
  • ROH and CPIC_LOOKUP are report-only by their channels but keep the stop by choice (KEEP_STOP); the check fails if either name goes stale.

Decisions

  • The scan errs toward silence: a process whose channel has any other consumer is not asked for. Widening it (multiline version mixes, which would bring HAPLOCHECK in) needs its own decision on whether that step should stop a run, so it is left for a follow-up.

How it was checked

  • bash tests/test_retry_codes.sh: both planted faults reported, then ok: both files retry exit codes [143,137,104,134,139,247].
  • python3 tests/test_contract_report_only.py: all eight checks pass on the head, including the planted pre-fix states.
  • Red on the pre-fix state: check-report-only.py run against main's main.nf, nextflow.config and workflows/ exits 1 and names CPSR_CDNA_CHECK and CLINVAR_CDNA_CHECK. With this branch's nextflow.config it exits 0.
  • The release asset was downloaded back from https://github.com/GeiserX/OwnGenome/releases/download/e2e-data-1/TRExplorer.repeat_catalog_v2.1.hg38.1_to_1000bp_motifs.bed.gz and its sha256 matches the pin.
  • Fast checks on head bc4ac48 (Guard unit tests, Nextflow 26.10 and pinned, Lint, shellcheck, actionlint, Personal data, Container Test) all green upstream.
  • e2e on the earlier head 59a255e, base leg and all six shards green: https://github.com/geiresx/OwnGenome/actions/runs/42597238463 . The head bc4ac48 changes only a comment in nextflow.config plus the new check and its test, none of which an e2e case runs.

Summary by CodeRabbit

  • New Features
    • ClinVar and CPSR cDNA checks are now included in report-only results. Their results are joined into reports, and failures are displayed.
  • Documentation
    • Updated E2E cache guidance to describe the pinned TRExplorer v2.1 download and mirror-first retrieval.
    • Expanded report-only documentation to explain the cDNA check tables and how failures appear in reports.

CLINVAR_CDNA_CHECK and CPSR_CDNA_CHECK write tables that only the
report joins (remainder joins), so they join the report-only
errorStrategy list: a memory or time kill retries once, any other
failure is ignored and named in failed_tasks.tsv.

Bead: pgp-pfw6
The pinned v2.1 catalog (sha256 df9c23c4...) is now an asset of the
e2e-data-1 release, so the catalogs fill tries the mirror before
broadinstitute's release.

Explain Change →

Walkthrough

The change updates TRExplorer cache documentation, documents report-only ClinVar and CPSR cDNA checks, and adds a script and tests that validate the report-only process contract.

Changes: TRExplorer cache documentation

Layer / File(s) Summary
Catalog retrieval documentation
docs/testing.md
The documentation describes the pinned TRExplorer catalog in the mirror and says a cache miss tries the mirror before the catalog’s GitHub release.

Report-only cDNA checks

Layer / File(s) Summary
cDNA check documentation and failure handling
nextflow.config
The documentation describes the report tables and the effect of failed checks. The report-only selector now applies the existing retry and ignore strategy to CPSR_CDNA_CHECK and CLINVAR_CDNA_CHECK.
Report-only process detection and validation
scripts/ci/check-report-only.py, tests/test_contract_report_only.py
The checker detects report-only processes and validates their configuration coverage, KEEP_STOP exceptions, and discovery results. Tests cover the current checkout and modified repository copies.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Possibly related PRs

  • GeiserX/OwnGenome#329: Updates the same TRExplorer documentation sentence with a conflicting retrieval order.
  • GeiserX/OwnGenome#320: Introduces the CPSR cDNA check and report join used by the report-only contract.
  • GeiserX/OwnGenome#326: Defines the CPSR cDNA alias and wiring referenced by the report-only configuration and scan.
Merge Risk: Low · up to bc4ac

The cDNA failure-handling change has no established blocking defect. The new checker has detection gaps and order-sensitive tests worth correcting, but the remaining risk is bounded and suitable for owner-aware follow-up.

Full details: Title check

Explanation

The title names the two main changes: keeping the cDNA checks from failing a run (adding CLINVAR_CDNA_CHECK and CPSR_CDNA_CHECK to the report-only list in nextflow.config) and the output contract naming both Parascopy legs. The raw summary and objectives match these points. The title is long (113 characters, 19 words) but it is specific and relevant to the changeset. It does not mention the new check-report-only.py script or the test file, which is acceptable because the title does not need to cover every detail.

Full details: Docstring Coverage

Explanation

Docstring coverage is 20.00% 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 5 functions across 2 files. (1 skipped: 1 unsupported.)

Resolution

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

- Line 179: Update the Nextflow configuration for `CPSR_CDNA_CHECK` and
`CLINVAR_CDNA_CHECK` so failures record the affected sample identities in a
separate report, using the trace or another supported source for sample
attribution. Preserve the existing two-column `failed_tasks.tsv` format consumed

…n-stopping error strategy

scripts/ci/check-report-only.py finds each workflow process whose channels
reach main.nf only through the report's remainder joins and fails when no
report-only withName block in nextflow.config names it. ROH and CPIC_LOOKUP
are listed as keeping the stop by choice. tests/test_contract_report_only.py
runs it in Guard with planted controls.

Review comments at @scripts/ci/check-report-only.py:
- Around line 69-76: Update the scanner around the `re.findall` and `re.match`
checks to recognize `proc.out.versions` when it appears inside a multiline
`ch_versions.mix(...)` call, so that process is not skipped and its error
strategy is checked. Add a regression test covering this multiline case without
changing handling of other process outputs.
- Line 42: Update the report-only block parsing in the checker so it recognizes
errorStrategy regardless of whether other settings appear before it. Preserve
the existing uncovered-process detection for blocks without that strategy.
- Around line 53-92: Update emit extraction in report_only_processes to identify
the workflow’s actual emit section rather than splitting on the last occurrence
of “emit:”. Ensure block-comment contents cannot replace or obscure the real
emit declarations, preserving emitted labels such as the ClinVar emits and their
ignore-selector checks.
- Around line 45-46: Update strip_comments to recognize string literals before
treating // as a comment marker, preserving URLs and other // sequences inside
strings while still removing actual comments. Ensure the report-join scanner can
inspect the remaining process and detect a missing report-only strategy.

Review comments at @tests/test_contract_report_only.py:
- Around line 61-75: Update the `plant` edits in this test so they remove each
cDNA name from the report-only list whether it appears at the start, middle, or
end of the alternation; target that block and handle its boundary delimiters.
Wrap temporary-directory use in cleanup that still runs if `plant`, `run`, or
`check` fails.
