Summary

Container export and the statistics dashboard choose Containers through one Container selection module (ADR 0011).

 runSingleStudyContainerExport*  (#96)
-  buildContainerQuery → filterContainerIdsByType → enrichContainerData(type filter)
+  selectContainers({ kind: 'study' | 'subjects' }) → enrichContainerData
 runMultiStudy / runBarcode      (#97)
-  buildMultiStudyContainerQuery (one query per Study, fake MULTI study)
+  selectContainers({ kind: 'subjects' | 'micronixBarcodes' })
 getDashboardStatistics          (#98)
-  inline all-tags intersection, unreachable location-only branch
+  selectContainers({ kind: 'study' | 'database' })
 GET /containers?tag_ids         (#99)
-  any selected Tag
+  containerHasAllTags(tagIds)

Also:

• GET /export/available-types reads only distinct types through selectContainerSelectionTypes, not every Specimen and Container row. A missing study is a typed ValidationError.
• JSON POST container exports return their rows again (they returned data: []).
• buildContainerQuery, lib/export/filter.ts, lib/container-tag-filter.ts and lib/statistics/location-filter.ts are deleted. enrichContainerData(database, containers) reads study fields from the Source.
• Uploaded barcodes and subject names resolve a chunk of SQL_IN_CHUNK_SIZE at a time, as ADR 0011 requires.
• A Subject's collection dates fold in one place, the contract's addSubjectDates. When a Subject is listed more than once, an undated entry wins, and ADR 0011 now says so.
• Every container type union derives from one list, CONTAINER_SUBTYPES. The selection result says whether a Container-level filter was set, and parseStatisticsFilters parses the statistics id filters.

Evidence

• Before: a subject list of 500 Subjects × 80 dates → expected 14964 values, received 80500. available-types for a Study with 70,000 Subjects → 500. A POST export with format: 'json' → data: []. subject_dates: { "S1": null } → 500. 70,000 uploaded barcodes or subject names → SQLite query expected 4466 values, received 70002.
  After: all pass. Container selection, export, statistics, identifier resolution and containers tests: 202 pass against the in-memory database, and the contract's 89 tests pass. bun run ci:verify passes: API 1211, web 949, contract 89.

Merge Danger

Door: two-way

Revertible per commit; no schema change.

Blast Radius: wire-semantics

GET /containers?tag_ids changes from any-Tag to all-Tags for external clients. GET study export returns 404 when every Container is filtered out by type. The dashboard's "Created" filter is relabelled "Specimen created". POST /export/containers answers 400 VALIDATION_ERROR for a malformed subject_dates, which it used to ignore or fail on with a 500. The available-types 400 body gains errorCode.
