ci(e2e): stop e2e legs timing out on EBI when the data cache is empty - #301
When the e2e data cache is empty (a fork has none, and main loses its entries after an eviction), shards 2 and 5 download the 1000 Genomes phase 3 sites file and the MoChA chr20 panel from EBI. EBI's 1000 Genomes hosts swing between a few KB/s and about 3 MB/s from one request to the next, so those legs ran into the 240-minute limit. Fork runs for four pull requests and one cache-seeding run hit it on 2026-11-05. No other public copy of the pinned v5c sites file exists: AWS's 1000genomes bucket has only v5b, and NCBI's path answers 404.
Fix
data_fetch in scripts/ci/e2e-run.sh tries each file once at E2E_DATA_MIRROR before its source. The pin (md5 or sha256) checks both copies the same way, so the mirror changes only where the bytes come from.
e2e.yml sets E2E_DATA_MIRROR to the pre-release e2e-data-1, which holds copies of the pinned files under their own names, the way fixture-v* holds the fixture.
A file the release lacks, or a copy that fails its pin, falls back to EBI as before.
docs/testing.md and docs/lessons-learned.md say so.
The user pipeline (setup.sh) is unchanged.
Checks
mfetch with file:// URLs. With the file on the mirror, it is used and EBI is never asked. With the file missing, or a corrupt copy that fails the md5, it falls back to the source. When both fail, it returns 1.
shellcheck -S warning (CI's level) is clean.
The E2E run on this branch shows whether shard 2 restores the 1000 Genomes sites from the release.
Bead: the e2e data mirror task filed on 2026-11-05.
Summary by CodeRabbit
Improvements
Automated test runs can retrieve pinned data from an alternate source before falling back to the original source.
Expanded testing guidance explains data caching, validation, retries, and running selected tests with cached data when network access is unavailable.
With no Actions cache for the 1000 Genomes sites file or the MoChA panel
(a fork, or an evicted entry), shards 2 and 5 download them from EBI, whose
1000 Genomes hosts swing between a few KB/s and MB/s, and the legs hit the
240-minute limit. No other public copy of the pinned v5c sites file exists.
data_fetch now tries E2E_DATA_MIRROR (the release e2e-data-1) once per file
before the source. The pin checks both copies, and a file the release lacks
falls back to EBI as before.
The E2E workflow now configures a GitHub release mirror for pinned data. e2e-run.sh tries the mirror for MoChA files and the archaic VCF, then falls back to the original source. E2E documentation describes caching, validation, retries, and network-blocked test paths.

Summary
Configure and use the pinned-data mirror .github/workflows/e2e.yml, scripts/ci/e2e-run.sh, docs/lessons-learned.md, docs/testing.md
The workflow sets E2E_DATA_MIRROR. mfetch tries the mirror for MoChA files and the archaic VCF, then uses the original source if the mirror is unavailable. Existing checksum checks remain. The documentation describes the mirror fallback and E2E download and cache behavior.
GeiserX/OwnGenome#260: Caches the MoChA panel and 1000 Genomes sites file, which are among the E2E downloads covered by this mirror fallback.
Merge Risk: Moderate · up to 3d996
A slow mirror download can exhaust an E2E shard before the original source is tried. Bound that attempt before merging; publish the missing MoChA assets to complete the intended cold-cache improvement.

The configured e2e-data-1 release contains only the archaic VCF and MD5SUMS. It lacks the MoChA manifest, VCF, and index. A cold mocha-1 run therefore falls back to EBI and can spend the 240-minute shard limit on the original slow transfer. Upload all pinned MoChA assets and update them with pin changes.

FETCH_TRIES=1 limits retries, not transfer duration. A continuously moving mirror transfer can run until the 240-minute leg timeout because _get has no overall deadline. Add a mirror-specific transfer deadline so mfetch reaches the pinned source fallback.

## Problem
Step 35 writes a copy-number interval table (`<id>_cn_intervals.tsv`), and the couple screen can read it to list the carrier deletion alleles and a male partner's AZF deletions. Nothing passed it in. Step 39 and the Nextflow couple screen left out the table and the CNVpytor calls that cross-check it, so those lines only showed up if you ran `couple_report.py` by hand. The Nextflow HTML report also never received the table, so `summary.json` had no interval rows in Nextflow even though the bash report reads them. Two beta-globin deletions were still missing, and step 35's docs did not list the table among its outputs.
## Fix
- Step 39 passes `paralogs/<id>_cn_intervals.tsv` (step 35) and `cnvpytor/<id>_cnvs.vcf.gz` (step 18) for each partner who has them.
- `COUPLE_CARRIER` matches both files by name. `main.nf` hands them over from `PARASCOPY` and `CNVPYTOR_VCF` through two new emits, `BAM_ANALYSIS.out.cn_intervals` and `SV.out.cnvpytor_vcf`.
- `HTML_REPORT` puts `<id>_cn_intervals.tsv` in `paralogs/`, where `collect_summary.py` looks for it, and `main.nf` joins it into the report inputs.
- Two new interval rows use HbVar's GRCh38 spans: the 619 bp HBB deletion (HbVar 979, Orkin 1979, PMID 287080) and the 13.4 kb Sicilian (delta-beta)0 deletion (HbVar 1035, Henthorn 1990, PMID 2307466). I checked both spans by placing 50 bp of NG_000007.3 on each side of each breakpoint on NC_000011.10. Both agree with HbVar's hg38 positions. The couple screen lists them as two more alleles. `docs/cn-loci.md` says that the rows only count copies over their span: a Sicilian carrier reads as a deletion on all three HBB rows.
- `cn-intervals-2-hg002` now checks HG002's AZFc_DAZ result, `not assessed` with reason `between_counts` and an estimate between 3.3 and 3.9. It reads 3.63 on this head (fork run below).
- The three beta-globin rows overlap: the Sicilian deletion covers both HBB rows, and the 619 bp and exon 3 rows share 487 bp. One deletion can read as present on two or three of them, so the couple report and `docs/39-couple.md` now say so, and that only a clinical test names the allele.
- Step 18 counts in 1 kb bins and cannot see a deletion of about 600 bp. The couple report no longer prints "CNVpytor calls no deletion here" for an allele shorter than 2 kb (the two HBB rows), where that silence is no evidence.
- `docs/35-paralogs.md` lists the interval table. `docs/39-couple.md` and `docs/cn-loci.md` no longer say the inputs are not passed.
Output changes, all additions: the interval table gets two new lines (`HBB_619bp_del`, `HBD_HBB_Sicilian_del`), and the couple report gets two new allele lines per partner. No column, file name or option was renamed or removed.
Decisions:
- pgp-19um (HBA dropped when a custom catalog has no SMN1 row) was fixed by #276, now merged; this PR only adds the interval-table case on top.
- The optional fixture region over a breakpoint row (`tests/test_copy_number.py`) is not done. The catalog check already keeps every target piece off breakpoint rows.
- #276 (merged) made step 35's report tables independent of the SMN table. With it merged in, `collect_summary.py` now also keeps the interval rows when step 35 wrote no other table at all.
- `scripts/ci/e2e-case-paths.tsv` gets one row for the new case. #297 made a row there required for every case, so the case could not run without it.
- Step 39 and `COUPLE_CARRIER` do not pass `--cyp21a2` yet. #280 added that option and merged after this PR was built; it is merged in here, but wiring it needs its own red controls and e2e checks, so it is left for a follow-up rather than added at the end of this one.
## How it was checked
- `tests/test_copy_number.py` and `tests/test_couple_report.py`: ALL PASS. Before the fix (the old `bin/cn_loci.tsv` and `bin/couple_report.py`), the two new copy-number checks (hand rows, HbVar spans) and the two new couple checks (five alleles, Sicilian and 619 bp present) fail.
- `scripts/ci/build-cn-intervals.py --check`: "the 90 interval rows are what the pinned downloads give". Only the two new rows changed.
- e2e on head 7d88aa4 (main merged in, with #280), fork run https://github.com/geiresx/OwnGenome/actions/runs/42134759461 , green in full. The head after it only merges main again (#301 runner cache fix and #285 docs), with no change to the code these cases run.
- `followups-cn-1-couple-report` passes in shard 5, https://github.com/geiresx/OwnGenome/actions/runs/42134759461/job/127636984222 . Step 39 on a made-up couple lists the alleles and AZF lines with the CNVpytor note beside them. `COUPLE_CARRIER` writes the same report and table as step 39, byte for byte. `HTML_REPORT` puts the interval rows in `summary.json`. A stub run of the stub pedigree stages both files in `COUPLE_CARRIER` and the table in every `HTML_REPORT` task. Each wiring line has a red control in the case, and all of them log `[PASS]`: one partner's table removed, a module copy without the two input kinds, a module copy without the place line (exit 1), a pipeline copy without the two lines (nothing staged).
- `cn-intervals-1-catalog` passes in shard 2 at 90 rows, https://github.com/geiresx/OwnGenome/actions/runs/42134759461/job/127636984447 , with its control (one moved target makes `--check` exit 1). It went red on the old count of 88 in e2e shard 2 of run 41853902601.
- `cn-intervals-2-hg002` passes in shard 3, https://github.com/geiresx/OwnGenome/actions/runs/42134759461/job/127636984198 . HG002 reads as male, AZFa 1.00 and AZFb 1.01 copies, `AZFc_DAZ not assessed, between two whole counts, estimate 3.3 to 3.9 (3.63)`, 22q11.2 A-B 2.06. The same AZFc check, run on the female table, fails as it should (`not applicable/no_y/out`), and that control logs `[PASS]`.
- The same cases also passed on the earlier heads cb0ef8c (https://github.com/geiresx/OwnGenome/actions/runs/42118893678) and 2662e8f (https://github.com/geiresx/OwnGenome/actions/runs/42091455296).
- `tests/test_couple_report.py` has a new check that no missing-call note is printed for the 619 bp and 621 bp rows while the 13.4 kb Sicilian row keeps it. It failed on the code before the fix (`RESULT: 1 FAILED`, the note was on both HBB lines) and passes after.
- The GJB6 pattern of the e2e case now escapes its parentheses. Against the exact report line, the old pattern gave grep exit 1 and the new one exit 0.
- `tests/test_copy_number.py` has a new check that the summary keeps the interval rows with no SMN table: `RESULT: 1 FAILED` before the `collect_summary.py` change, `ALL PASS` after.
- Fast checks on the final head (main merged in, with #280, #285 and #301): every one is green, including unit-tests, shellcheck, actionlint, nextflow (pinned), build (strict), container-ok and ci-ok. `scripts/ci/e2e-scope.sh check` passes with the new case's row in `scripts/ci/e2e-case-paths.tsv`, and says `case followups-cn-1-couple-report has no row` without it.
