refactor(ancestry): stream archaic and ancient reports with exact stats - #402
Steps 43 (archaic ancestry) and 44 (ancient similarity) ran their own logic in two Python files, bin/archaic_report.py and bin/ancient_report.py. The setup of step 43 builds a table of about 52 million sites with that Python. A step that stopped could leave a half-written table, genotype file or panel column behind. Some reports were written in place.
The setup stamp of the archaic table held the sha256 of the Python's table code. Deleting that file would make every install download about 150 GB and rebuild the table.
Fix
The nine commands now run in the Rust og binary, in the og-ancestry crate:
Verb
Replaces
og archaic table, strict, genotypes, report
the four commands of archaic_report.py
og ancient select, lift, person-geno, align, report
the five commands of ancient_report.py
og ancient lift reads UCSC's chain file with a new reader, og-intervals::chain. og is static, so each part still runs in the image it ran in. Both Python files are deleted. The step scripts, the Nextflow modules, setup.sh --archaic and setup.sh --ancient-panel call og.
The table merge reads the four inputs together in one pass, with a forward cursor per mask. genotypes streams the sorted VCF and table together. It reduces duplicates at one position with pick_call and keeps one record of lookahead. Mask runs are written as they close. strict checks each row against the previous one instead of keeping a set of every position. person-geno streams the panel's .geno rows and appends one column.
The archaic table stamp
The stamp now holds a format id, ARCHAIC_TABLE_FORMAT=archaic-table-v1 in setup.sh. A stamp that holds the last Python code hash is taken as current once and rewritten. This is safe only because og archaic table and strict write the same bytes as the Python did. The parity cases show that on synthetic inputs, and the real-table check below shows it on the real table. The legacy line is marked for removal one release after 1.0.0.
Check on the real archaic table
The table is built from public files only: the snpAD VCFs of the three archaic genomes, the 1000 Genomes phase 3 sites, UCSC's hg19ToHg38 chain, the MPI-EVA FilterBed masks and the 1000 Genomes GRCh38 strict mask. We rebuilt chromosomes of an installed table with og from this head. The table was the one the last Python built (snpad2016-1kgp3-v2, stamp code=6bdc4c99...). The rebuild ran every step of install_archaic with the pinned bcftools 1.24 and Picard 3.5.0 images. We compared each rebuilt chromosome with the installed one after decompression. As a cross-check, the last Python (fe6b67e0) ran on the same intermediate files, and its table and strict outputs were compared with og's byte for byte. The og binary was a Linux x86_64 musl build of this head's rust/ tree (88a8cfd6).

Times are wall time and memory is peak RSS, for each command alone on the same host. All 23,541,982 rows (45% of the table's 51,812,908) are the same. On every chromosome, og's table and strict outputs equal the Python's byte for byte. The rebuilt exclusion lists also equal the installed ones. The rest of the genome was not rebuilt. It needs about 2 more hours, mostly to download the archaic VCFs. The table memory grows with the chromosome because each mask is held as sorted intervals, as the Python held it. Most of each chromosome's setup time is bcftools and Picard, not the merge.
What changes on purpose
og archaic genotypes requires positions within each chromosome of the VCF and table to be sorted. A position that goes backwards stops with exit 2. The old chromosome-return check keeps its error and exit code. Duplicate, clash, masked-site, mask-run and span behavior stays the same. The tests also check ignored VCF records and the tail past the last table site.
og archaic strict reads the lifted rows in position order, as Picard writes them. A row that goes back stops it with exit 2 (golden archaic-strict/unsorted).
Every output is written to a temporary file and renamed. A step that stops leaves no partial file (goldens archaic-table/unsorted, archaic-genotypes/bad-code and the three ancient-person-geno cases).
A gzip input is told by its first bytes, not by a .gz name. A .fai that does not match its FASTA stops og ancient lift.
Malformed input stops with one ERROR: line, not a traceback.
No option, output file name or format changes.
Decisions kept as they were
sites_genotyped in step 44's stats still counts a position twice when the AADR holds two SNPs there. The genotypes are right. Fixing the count changes an output, so it is left for its own change.
The tools are not added to OG_SHADOW. They have goldens, and shadow mode compares bytes, while the gzip genotype files differ in their compressed bytes.

The outputs were the same in each run (gzip files by content). The real masks are much larger than the synthetic ones; the real-table check above gives the real cost of table.
The streaming fix was measured separately on the same synthetic chromosome for both versions, with 3,000,000 table rows, 1,000,000 VCF records and masked runs. Both binaries used the same release profile and compiler on the same box. /usr/bin/time -l measured wall time and peak RSS.

How it was checked
The new input-order and output-preservation checks fail eight assertions on bb71d569 and pass after the fix.
Guard plants a split duplicate-position window in its working copy. It runs cargo test --no-fail-fast and requires that exact regression to fail. It restores the source before the normal workspace test. No planted fault is committed. The same control fails locally for the expected reason. The normal 68 crate tests then pass. Both original mask/chain-end planted faults were also rechecked locally on the final head. They fail their two named tests, and all 68 tests pass after restoring the source.
Parity harness, local oracle: all 227 items in 49 cases agree. oracle-diff --self-test: its harness and 44 comparator checks pass. The Linux-only shadow sub-check is skipped locally.
cargo test --no-fail-fast -p og-ancestry -p og-intervals: 68 tests pass after the streaming fix, on both the local compiler and pinned Rust 1.93.0. Clippy -D warnings, rustfmt and cargo doc -D warnings are clean.
tests/test_archaic_report.py with OG set passes with the Docker part skipped locally. tests/test_ancient_report.py passes.
og dev remnants, og dev contract --static, e2e-scope.sh check and tests/test_e2e_shards.sh pass.
Red controls: commit 3b492b9a planted a mask using the wrong coordinate base and a chain block including its end. Both faults were present on CI head 0a23652f.
Red parity job: exactly six differences among 4,045 items in 995 cases, all in archaic-table and ancient-lift.
Red cargo test step: cargo test --workspace --locked --no-fail-fast failed only archaic::tests::a_mask_holds_its_bed_bases_only and chain::tests::block_ends_are_half_open. The job was then cancelled during the later CPython comparison to stop work on the planted head.
Revert bb71d5692e77523235e27243e6453b9d4f3e4cf2 removes both faults and is pushed. On this clean head, 67 Rust tests pass. All 227 lane oracle comparisons in 49 cases pass, as do 15 harness self-checks and 44 comparator self-checks. The archaic test passes with its Docker part skipped, and the ancient test passes.
Full E2E cases archaic-ancestry-1 and ancient-similarity-1 were not run here. They need the GIAB fixture, setup downloads, and container support the local machine lacks. E2E runs at landing.
The real-table check above covers the stamp migration of bead pgp-bs9u.21. It ran on 7 of 22 chromosomes, not on the whole genome.

Changes: Archaic and ancient Rust commands
Layer / File(s)
Summary
Chain-file liftover and ancient selection rust/crates/og-intervals/src/chain.rs, rust/crates/og-intervals/src/lib.rs, rust/crates/og-ancestry/Cargo.toml, rust/crates/og-ancestry/src/ancient.rs
The intervals crate parses UCSC chain files and lifts single positions. Ancient selection filters modern and ancient samples, and ancient liftover uses the new chain support.
Ancient genotype, alignment, and report commands rust/crates/og-ancestry/src/ancient.rs, tests/test_ancient_report.py
The ancient commands add genotype extraction, PCA-axis alignment, population ranking, and TSV, info, text, and SVG report generation. The CLI tests exercise these commands.
Archaic table, genotype, and report commands rust/crates/og-ancestry/src/archaic.rs, tests/test_archaic_report.py, .github/workflows/guard.yml
The archaic commands add table construction, strict-mask processing, genotype generation, and segment reports. Tests cover input ordering and duplicate handling; the guard workflow adds a targeted duplicate-window control and runs the archaic CLI tests.
The top-level CLI dispatches the new command groups. Setup and pipeline invocations switch to og; cache stamps, CI, tests, and documentation are updated. The two Python report scripts are removed, and archaic_compare.py defines its own IBDmix parser.
The Rust archaic and ancient reports replace the Python tools. Several edge cases can produce wrong results or damage previous outputs:
Unsorted VCFs across chromosomes can silently drop real calls.
Failed genotype runs can delete or mismatch previously generated files.
Malformed ancient PCA inputs can yield misleading rankings instead of errors.
These should be fixed before merging.

Unlike to_float, need_float does not reject NaN or infinity. If the Person row contains NaN, the present-day axis checks still pass. The report then computes NaN distances and emits invalid SVG coordinates instead of returning an error.

Require every ancient member to contain all distance PCs.
This minimum silently shortens the distance calculation. With four selected PCs, person [0, 0, 10, 0], and unit eigenvalues, an ancient row [0, 0] receives distance zero. It ranks ahead of a complete row [0, 0, 9, 0], whose distance is one.
The axis checks inspect present-day rows, and the plot accepts two coordinates. The report therefore succeeds while claiming pcs_in_distance=4. Require at least n_pcs coordinates for every ancient member, and calculate every group centre over exactly those PCs.

Preserve duplicate-call evidence throughout the position window.
At one position, G:0/0, T:0/0, then G:0/1 reduces to G:0/1. These lines discard the first two ALT identities, so the later call replaces the reference state.
If the two G records occur first, they produce Clash instead. The same contradictory calls therefore produce different genotypes depending on their order.

Do not delete the previous genotype file on an empty failed run.
If every table row has a different sample allele, n remains zero. Dropping gz discards the temporary output, but this call also deletes the previous final genotype file.
If no other chromosome produces rows, cmd_genotypes then returns an error. The failed run has destroyed the previous genotype while leaving its previous masks in place.

Problem
Steps 43 (archaic ancestry) and 44 (ancient similarity) ran their own logic in two Python files,
bin/archaic_report.pyandbin/ancient_report.py. The setup of step 43 builds a table of about 52 million sites with that Python. A step that stopped could leave a half-written table, genotype file or panel column behind. Some reports were written in place.The setup stamp of the archaic table held the sha256 of the Python's table code. Deleting that file would make every install download about 150 GB and rebuild the table.

The rebuild ran every step ofinstall_archaicwith the pinned bcftools 1.24 and Picard 3.5.0 images. We compared each rebuilt chromosome with the installed one after decompression. As a cross-check, the last Python (fe6b67e0) ran on the same intermediate files, and itstableandstrictoutputs were compared with og's byte for byte. Theogbinary was a Linux x86_64 musl build of this head'srust/tree (88a8cfd6).tableog / Pythonstrictog / PythonTimes are wall time and memory is peak RSS, for each command alone on the same host. All 23,541,982 rows (45% of the table's 51,812,908) are the same. On every chromosome, og's
tableandstrictoutputs equal the Python's byte for byte. The rebuilt exclusion lists also equal the installed ones. The rest of the genome was not rebuilt. It needs about 2 more hours, mostly to download the archaic VCFs. The table memory grows with the chromosome because each mask is held as sorted intervals, as the Python held it. Most of each chromosome's setup time is bcftools and Picard, not the merge.What changes on purpose
og archaic genotypesrequires positions within each chromosome of the VCF and table to be sorted. A position that goes backwards stops with exit 2. The old chromosome-return check keeps its error and exit code. Duplicate, clash, masked-site, mask-run and span behavior stays the same. The tests also check ignored VCF records and the tail past the last table site.og archaic strictreads the lifted rows in position order, as Picard writes them. A row that goes back stops it with exit 2 (goldenarchaic-strict/unsorted).archaic-table/unsorted,archaic-genotypes/bad-codeand the threeancient-person-genocases)..gzname.

Decisions kept as they were
sites_genotypedin step 44's stats still counts a position twice when the AADR holds two SNPs there. The genotypes are right. Fixing the count changes an output, so it is left for its own change.OG_SHADOW. They have goldens, and shadow mode compares bytes, while the gzip genotype files differ in their compressed bytes.Measurements on synthetic inputs

The new input-order and output-preservation checks fail eight assertions on
bb71d569and pass after the fix.Guard plants a split duplicate-position window in its working copy. It runs
cargo test --no-fail-fastand requires that exact regression to fail. It restores the source before the normal workspace test. No planted fault is committed. The same control fails locally for the expected reason. The normal 68 crate tests then pass. Both original mask/chain-end planted faults were also rechecked locally on the final head. They fail their two named tests, and all 68 tests pass after restoring the source.Parity harness, local oracle: all 227 items in 49 cases agree.
