Problem

The two-hit rule pairs a deletion with a small variant in the same gene, and read-backed phase decides cis or trans. For deletions that AnnotSV annotated, that phase never arrived: step 05's checked class 4-5 table dropped the FORMAT and sample columns, so every AnnotSV deletion had no GT and no PS. A deletion and a ClinVar hit on different copies of MUTYH, in one phase set, read as "phase unknown, possibly in trans" instead of "biallelic, in trans". Once GT arrives, a deletion genotyped 0/0 must not pair at all.

The couple doc said a hypomorph is never a carrier finding on its own, but did not say the screen now counts one beside the partner's full loss of function.

On the archaic side, the public-evidence.yml summary still told readers not to compare the share with published figures. That was right before the masks and is wrong now. The workflow could only run all 22 chromosomes (22 jobs, 150 GB of archaic data), and docs/testing.md said the archaic e2e case runs on a slice when it builds the whole of chr22.

Fix

  • bin/annotsv_postfilter.py: the checked table now ends with AnnotSV's FORMAT column and the sample column after it. Columns are only added at the end, so existing readers that look columns up by name are unaffected. An input without FORMAT writes neither. A sample named like a checked column (for example Caller) would lose its GT and PS, so that stops the step with an error instead.
  • bin/collect_summary.py gene_deletions: an AnnotSV deletion genotyped 0/0 or 0|0 is skipped.
  • docs/39-couple.md: one paragraph saying the couple screen counts a hypomorph beside the other partner's full loss of function (an autosomal recessive gene is then shared, an X-linked one stays x_linked) (RBM8A with a deletion that removes it, the TAR pair), and that a hypomorph in both partners or in one alone stays set aside.
  • .github/workflows/public-evidence.yml: when all 22 autosomes ran, the summary says whether HG002's Neanderthal total, compared in bases, is inside, below or above the 49.9 to 82.9 Mb that Chen et al.'s released per-person calls give Europeans (Altai and Vindija union, LOD 4, 50 kb). On a subset it prints the total and says the whole-genome range does not apply. A chromosomes input (default all) picks the autosomes, separated by commas, spaces or new lines. An ancient input (default on) can skip the ancient-footprint job, so a one-chromosome proof run does not hold a runner for an hour.
  • docs/testing.md: the archaic case runs the whole of chr22, and the two inputs are documented; a one-chromosome run is that chromosome's job plus the empty control.

Output change: <sample>_sv_class4_5_checked.tsv gains two columns at the end. Nothing is renamed or removed.

Decisions:

  • docs/05-annotsv.md lists the checked table's columns and is outside this package's file list. Its table stays true but does not name the two new columns yet. The plan's file list names a docs/22-annotsv*.md that does not exist, so docs/05-annotsv.md stays untouched here. Left for a follow-up.
  • The ancient input is extra to the bead. It is there so the one-chromosome proof uses one runner, not two.

How it was checked

  • New check 29 in tests/test_collect_summary.py runs the real postfilter on an AnnotSV row with GT:PS, then the two-hit rule. A MUTYH deletion 0|1 and a ClinVar hit 1|0 in phase set 45330000 give biallelic, "in trans". The same deletion 0/0 gives no two-hit line. Red before the fix: with bin/ reverted all three checks fail (the header had no FORMAT, both cases read "phase unknown, possibly in trans"). With only the postfilter fix, the 0/0 check alone fails.
  • tests/test_annotsv_postfilter.py: a new check that every written row keeps FORMAT and the sample column. It fails on the old postfilter and passes now. A second new check feeds a sample named Caller: on the previous postfilter it exits 0 and drops the genotype (red, run locally), now it stops with the error.
  • actionlint is clean on the workflow. The chromosome plan step was run locally on all, empty, 22, 22, 1,22, 23 and x: all 22 parts, all 22, ["empty","22"], ["empty","1","22"], and an error for the last two. After the review: 22 and 21 on two lines give both, 22 and X on two lines are rejected; the range label reads 49,860,000 bases as below and 49,900,000 as inside.
  • One-chromosome dispatch of public-evidence.yml from this branch (chromosomes=22, ancient=false): https://github.com/GeiserX/OwnGenome/actions/runs/42089578470 passed. It ran four archaic jobs instead of 25: archaic-sites, two per-chromosome jobs (the empty red control, which failed as it must on the empty region list, and chr22), then archaic-share; ancient-footprint was skipped. chr22 took 1.78 GB of archaic downloads and gave 628,371 table rows. The summary printed HG002's 1.3 Mb (ALL frequencies) and 1.7 Mb (EUR) of Neanderthal sequence on chr22 and said the whole-genome range does not apply to one chromosome.
  • The first dispatch, https://github.com/GeiserX/OwnGenome/actions/runs/42083232523, failed in archaic-share: download-artifact puts a lone matching artifact straight into its path, without the archaic-part-<n> folder. A step now gives a lone part its folder. That red run is the reason for the third commit. The 22-chromosome comparison line itself only runs on a full dispatch, which installs 150 GB and belongs to the release gate.
  • Fast checks are green on the head after merging main (which brought in ci(e2e): run only the e2e cases a pull request can affect #297).

Beads: pgp-pfw6.43, pgp-pfw6.42

The checked class 4-5 table dropped FORMAT and the sample column, so a
deletion AnnotSV annotated never carried GT or PS into the two-hit rule:
a phased deletion and a phased hit in one phase set read as "phase
unknown". The table now ends with both columns. A deletion genotyped 0/0
is no deletion and no longer pairs. The couple doc says the screen counts
a hypomorph beside the partner's full loss of function.

Bead: pgp-pfw6.43
…, and run fewer chromosomes

The archaic-share summary still told readers not to compare the share
with published figures; after the masks it compares HG002's Neanderthal
total with the 49.9 to 82.9 Mb of Chen et al.'s released European calls
when all 22 autosomes ran. A chromosomes input runs the archaic jobs on
a subset (one chromosome instead of 150 GB), and an ancient input can
skip the ancient-footprint job. docs/testing.md says the e2e case runs
the whole of chr22, not a slice.

Walkthrough

The changes add chromosome and ancient-footprint options to the public-evidence workflow, preserve AnnotSV genotype columns for downstream analysis, skip reference-only deletion calls, and update carrier-list documentation.

Changes: Public-evidence workflow

Layer / File(s) Summary
Workflow inputs and chromosome planning
.github/workflows/public-evidence.yml
The workflow accepts chromosome selections and plans a matrix from validated, sorted autosome values, with an empty control.
Selected-run reporting and workflow documentation
.github/workflows/public-evidence.yml, docs/testing.md
The report handles a lone artifact and selected chromosome counts. It compares HG002 with the published range only when all 22 autosomes ran. The ancient job is conditional on its input, and the documentation describes these options and reporting behavior.

AnnotSV genotype preservation and deletion pairing

Layer / File(s) Summary
Preserve genotype data and process deletion evidence
bin/annotsv_postfilter.py, bin/collect_summary.py, tests/test_annotsv_postfilter.py, tests/test_collect_summary.py
The postfilter retains FORMAT and sample columns. Summary processing skips reference-only deletion rows; tests cover retained values and phased deletion/ClinVar pairing.

Carrier-list guidance

Layer / File(s) Summary
Document hypomorph handling
docs/39-couple.md
The documentation describes when a hypomorph counts as a shared finding between partners.

Explanation

The title names two changes: keeping AnnotSV genotype and phase so deletions pair in trans, and fixing the archaic evidence summary. The changeset covers both. The postfilter now keeps FORMAT and sample columns, collect_summary skips 0/0 deletions, and the workflow and docs cover the archaic summary changes. The title is specific and matches the main changes, though it is long at 105 characters.

Share

download-artifact writes a single matching artifact straight into its
path, so a one-chromosome dispatch had no parts/archaic-part-<n> folder
and the share job failed on a missing setup.tsv.

Minor · Functional Correctness · Poor tradeoff

Keep sample genotype when a sample name matches a checked column.

A sample named ID or Caller is dropped from the checked table. Its GT and PS are lost, so deletions skip the 0/0 check and pair without phase.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

read consumes only the first line of CHROMOSOMES, so subsequent lines bypass chromosome validation and selection.

The workflow silently runs chromosome 22 only, rather than rejecting the unsupported input or including the additional requested chromosome.

This can occur when: A dispatch supplies a multiline value such as 22\n21 or 22\nX.

Review follow-ups, both fixed in 2bcaa51:

  • bin/annotsv_postfilter.py:335, a sample named like a checked column: the step now stops with an error naming the column instead of dropping the sample's GT and PS. tests/test_annotsv_postfilter.py has a check with a sample named Caller; it fails on the previous postfilter (exit 0) and passes now.
  • public-evidence.yml, a multiline chromosomes value: commas, CR and LF are all separators now, so 22\n21 runs both and 22\nX is rejected.
    Docstring coverage: not a gate in this repo, left as is.
