GeiserX#291

Summary by CodeRabbit

  • Documentation
    • Added a guide describing which command options, configuration settings, and result files remain stable across 1.x releases, and how changes are classified.
    • Expanded the reference and testing documentation with details about compatibility checks and their coverage.
  • Tests
    • Added checks that validate stable result files and their required contents, and detect changes such as missing files, fields, or keys.

…nd check them against the code

assets/output_contract.tsv lists what 1.0 keeps stable. The static check
fails on a removed or renamed stable item and on a new one with no row;
tests/test_output_contract.py plants each break and requires it to fail.

Bead: pgp-5bja.18
…ntract

Red control in the same case: a dropped column and a renamed file on a copy.

Bead: pgp-5bja.18
…t runs the static check

The planted copy now carries pipeline_info, so it fails only on the two
plants, and the case counts exactly two FAIL lines. The doc and the TSV
header name Guard's unit-tests job, and the doc says the two files
run-all.sh writes itself are listed but not yet checked.

Walkthrough

The pull request documents OwnGenome 1.0’s 1.x stability contract and adds static and run-output checks against that contract. It also adds unit and HG002 end-to-end tests for the checker.

Changes: Output Contract

Layer / File(s) Summary
Stability contract and documentation
docs/output-contract.md, docs/index.md, mkdocs.yml
The contract documents stable, experimental, and internal rows; allowed and breaking changes; and procedures for output changes. The guides and reference navigation link to it.
Contract parsing and static checks
scripts/ci/check-output-contract.py
The checker validates contract rows and compares parameters, tools, switches, and published process outputs with repository declarations.
Pipeline output validation
scripts/ci/check-output-contract.py
The checker validates stable output paths and required fields for a selected leg. The CLI reports contract and output-check failures.
Checker tests and HG002 end-to-end check
tests/test_output_contract.py, tests/e2e/output-contract-1-hg002.sh, docs/testing.md, docs/output-contract.md
Tests cover static mismatches, malformed rows, and missing files or fields. The HG002 check validates Bash and Nextflow outputs and tests planted output changes.

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

Possibly related PRs

  • geiresx/OwnGenome#14: Adds a pipeline result table that the output contract checker can validate.
  • geiresx/OwnGenome#27: Adds an E2E timing-table requirement that applies to the new output-contract E2E case.
  • geiresx/OwnGenome#15: Adds a tool, schema parameters, and a Nextflow process output covered by the contract checks.
Merge Risk: Moderate · up to bae26

A breaking change can pass CI if its contract entry changes with the code. Add comparison against the stable contract before merging.

Security architecture risk: Low · up to bae26

The change adds compatibility validation without changing production execution or privileges. No introduced security issue was established, but validation coverage is selective and the available security assessment is incomplete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The supported exposure is the invoking CI or local test process, its readable repository and output files, and its logs. The inspected change does not introduce a production service entrypoint or expand deployment authority.

Trust Boundaries and Controls

  • observed — Repository rows and CLI arguments determine which local files are inspected. Parsing validates contract structure and enumerated values, but the CLI is not a filesystem sandbox. The inspected callers supply repository-controlled contract paths and fixture output directories rather than accepting requests from a newly exposed remote interface.

Resilience and Maintainability Implications

  • observed — Planted unit-test changes use fresh temporary directories with finally-based cleanup. The end-to-end mutations target a case-namespaced copy, recreate that planted directory on repetition, and replace the edited table through a temporary file. No production rollback or shared production-state transition is introduced; interruption can leave test-local files behind.

Explanation

Docstring coverage is 33.33% 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 21 functions across 3 files. (1 skipped: 1 unsupported.)

Resolution

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

Main now requires every e2e case to have a row in e2e-case-paths.tsv and
e2e-case-times.tsv, so the fork run stopped at e2e-scope. The case reads
only base outputs, so it needs no shard case. Its paths cover every step
script, helper, module and asset: any of them can change a contracted
output, and the case runs in seconds.

Ensure the experimental-row control exercises a row.

If the bloodtype row is renamed or removed, the control can pass without testing experimental-row enforcement.

Assert that exactly one row matches and that its stability is experimental. Select the e2e column by name from the contract header instead of using 7.

assets/output_contract.tsv in e2e-case-paths.tsv. Set needs to “-” so the base

Report gzip read errors as contract failures.

If a contracted gzip file raises EOFError or OSError while the checker reads its fields, the checker exits with a traceback and does not print the accumulated FAIL lines.

Locityper (step 53: its tool, two params and three outputs), the CYP21A2
depth and PSV table of step 35 and the Y private-SNP table of step 37
reached main after the contract; the static check refused all eight.
Each is listed as experimental, with the leg that writes it.

Compare stable rows with an earlier contract.

If a PR removes allow_unfiltered from the schema, implementation, and contract, the contract checks can pass without retaining the old option. This bypasses the promised compatibility check.

Compare PR contracts against the previous stable contract, and add a test that removes a stable item and its row together.
