Per-test placement (per `porting-tests/detailed_plans/Parser.md`):

- `src/allele.rs::tests::port_parser_*` (4 tests): subtests #17 (GA/GT
  minimise via `vcf_to_vep_allele`), #18/#19 (MNV-preserves-suffix —
  documented divergence from Perl's broader trim per Ensembl-Variation
  `trim_sequences()` rule at allele.rs:300-302), Axis B B1 (degenerate
  same-allele input collapses to "-/-" under MNV rule).
- `src/transcript_consequence.rs::tests::port_parser_*` (3 tests):
  subtests #31 (bare chrom in valid set), #32 (`chr` prefix stripped
  by `normalize_chrom` then matches), #34 (unknown chrom rejected).
- `tests/port_parser.rs` (4 tests): subtests #7 (nonexistent path —
  catches panic from `object_storage.rs:183` unwrap), #12 (gzipped VCF
  reads), #57 (CRLF line endings tolerated), Axis B B3 (`.vcf.bgz`
  extension routes through gzip reader).

Axis B B2 (`buffer_variant_bounds` multi-chrom first-chrom-wins) is
cross-referenced — already covered by
`src/annotate_provider.rs::tests::port_input_buffer_axisB1_buffer_variant_bounds_multi_chrom_binds_to_first_chrom`.

Coverage parity: 12 / 77 Perl-denominator unit-ports (incl. 3 Axis B);
47 architectural-no-analogue rows documented inline in
`tests/port_parser.rs` (multi-format Parser base class, `validate_vf`
warning emission, lowercase coercion, DB mode/LRG, 27 `detect_format`
/ STDIN / factory-dispatch rows); 21 blocked-future-work rows as
commented-out stubs (all fold into existing future-work-vepyr.md
entries — SO-term cluster engine blocker #2 × 6, chromosome-synonyms
× 4, check_ref × 5, lookup_ref × 4, Uploaded_variation × 1,
chr_filter × 1). **0 new future-work entries created**.

- sztywno 1:1: every Perl subtest gets a Rust analogue (test or
  documented stub).
- standalone: no docker, no golden.vcf, no run_and_compare_csq.

cargo test: 11 active passing tests across the 3 files; full lib
suite 834 passed / 0 failed.
