API Reference: small 16S ribosomal RNA example for POST /v1/jobs

Motivation

The API Reference page's POST /v1/jobs card shipped a single curated request body example (Mode B - Web BLAST-equivalent core_nt). That makes the Try it surface unusable until the core_nt database (~700 MB) is staged in workload Storage and warmed on AKS. On a brand-new deployment the small 16S_ribosomal_RNA database (~50 MB) is the first thing the Get-started guide tells researchers to download, so it should also be the default Try it example.

User-facing change

The Request Body dropdown of POST /v1/jobs in the API Reference page now lists:

1. Small - 16S ribosomal RNA (~50 MB DB) — default selection. Uses db: "16S_ribosomal_RNA", the E. coli K-12 MG1655 16S rRNA partial query (NR_024570.1, ~490 bp), evalue 0.01, max_target_seqs 50, outfmt 5, and resource_profile: "standard".
2. Mode B - Web BLAST-equivalent core_nt — unchanged.
3. Any other examples published by the upstream OpenAPI spec, in their original order.

Researchers can now exercise the /v1/jobs Try it flow as soon as the small 16S database is Ready, without having to wait for core_nt to stage.

API / IaC diff

None. The change is a frontend static-data update only:

• web/src/pages/apiReference/spec.ts — added SMALL_16S_RRNA_FASTA + SMALL_16S_RRNA_JOB_EXAMPLE, prepended small_16s_rrna in withCuratedRequestExamples, and made getDefaultRequestExampleKey prefer it for POST /v1/jobs.
• web/src/pages/apiReference/spec.test.ts — updated the curated-examples and default-key tests to assert the new ordering and default selection.

No backend, OpenAPI, or Bicep change. The db: "16S_ribosomal_RNA" value is already a first-class entry in api/tasks/storage/helpers.py::BLAST_DATABASES, so the rest of the submit pipeline (admission gates, OpenAPI proxy, results download) needs no adjustment.

Validation

• cd web && npm test -- --run src/pages/apiReference/spec.test.ts — 5/5 passing (new ordering + default-key assertions).
• cd web && npm test -- --run — 51 files / 383 tests passing.
• cd web && npm run lint — clean (0 warnings).
• cd web && npm run build — production build succeeds.
• Manual: opened POST /v1/jobs card in the API Reference page; the dropdown shows Small - 16S ribosomal RNA (~50 MB DB) selected by default, switching to Mode B - Web BLAST-equivalent core_nt replaces the body with the core_nt example unchanged.
