// Ported from chibistar/automation/starr/test-courses-{newcourse,archive-final,
// assessment-archive}.cjs — see ~/Downloads/Courses_Test_Case_Documentation.txt.
//
// The source scripts were written as a manually-run, multi-phase live-site
// session (phase B1 writes a JSON handoff file that phase B2 reads, some
// checks assume "an earlier interrupted run already did X", row-count
// assertions assume exactly one pre-existing live course). None of that is
// safe to rerun unattended in CI, so this rebuilds the same TC-ID coverage
// as one self-contained, idempotent run: every fixture is created fresh
// under this run's own [QA-TEST] tag and torn down in afterAll — no
// cross-script file handoff, no assumptions about what else exists in the DB.
//
// Not ported (dropped, not silently — see apps/e2e/README or the PR that
// introduces this file): TC-CRS-001..009/028/030/042/043/046 (Refresh/Export/
// column-persistence checks tied to exact live single-row counts or file
// downloads) and TC-CRS-058 (jump-to-question, minor UI convenience).
