# =============================================================
# OxiCloud – Dedup blob lifecycle (bugs 3 & 4)
# =============================================================
# Verifies that when two files share the same blob (dedup hit)
# and both are permanently deleted, the blob lifecycle is correct.
#
# Bug 3: blob not deleted when last file reference is removed
# Bug 4: blob-keyed thumbnail not cleaned up with the blob
#
# Sequence:
#   1. Upload dedup-test.jpg twice → two file records, one blob
#   2. Both thumbnails return identical bytes → proves shared blob
#   3. Permanently delete file 1 → file 2 thumbnail still 200
#      (proves blob NOT prematurely deleted — bug 3 detection)
#   4. Permanently delete file 2 → blob and thumbnail cleaned up
#
# NOTE: The /api/dedup/stats endpoint counts CDC chunk rows in
#       storage.blobs and derives bytes_saved from chunk_manifests.
#       Both tables may be 0 when the CDC path is disabled or the
#       server uses the legacy blob path — so we avoid stats-based
#       assertions and rely on observable thumbnail behaviour instead.
#
# BLAKE3 hash of fixtures/dedup-test.jpg (= dedup-test-2.jpg content):
