Closes the remaining integration-suite failures (handoff open bug 3),
line by line:
- Fixture family (the upsert equivalence): tags_filter_test
("Science Fiction" found 1 of 3; "Fantasy" 404'd on zero results),
media_item_isbn_test (normalization read back the first case's ISBN
everywhere; edge cases saw a nil ISBN; pagination collapsed 5
creates onto 1 row), search_unified_test (its 3 books were actually
1 row + two no-op creates) — all POSTed a constant file_path into
one library while CreateMediaItem upserts ON CONFLICT
(library_id, file_path). Every fixture now uses unique per-item
paths, the suite's universal convention elsewhere. TestTagsFilter
confirmed same-family: counts came right with no second bug.
- New TestMediaItemCreateDuplicatePath pins the honest-create
contract from da13898: 201 for the first create; 200 + duplicate
flag + the EXISTING row (never a 201 lie), second payload not
overwritten.
- library_browse_test: the admin subtest browsed the container's
/tmp and required it non-empty — env-coupled (empty /tmp → "was
[]"). Now browses a self-created t.TempDir with two subdirs and a
decoy file, asserting ONLY directories are listed.
- series_integration_test: three stale assertions re-anchored to the
shipped contracts, each with a ground-truth comment: /dashboard/
sections key identity on the collection NAME (BuildSections ID =
CollectionName; the web/app reorder + hidden prefs persist those
strings) — the kebab query_type is the storage key and is not
exposed; /api/series/books is name-ONLY (the app client and the
web SSR page both send name only; library_id is ignored, never
validated); /api/series is optional-scope BY DESIGN (GetDistinct-
Series: narg IS NULL OR library_id = narg aggregates across
libraries when omitted). The former 400-on-missing-library_id
expectations asserted validation that never shipped.
- gofmt rider on three untouched-in-this-arc test files
(dashboard_integration, search, test_helpers).
Full suite with -parallel=1: 217 groups pass, zero failures.
