An interrupted blob upload was silent data loss: the packer writes a blob's chunks, blob_chunks, and blobs rows to the local index before the upload is attempted (internal/blob/packer.go). If the upload failed, those rows survived, and the next run deduplicated against chunks whose data never reached storage, then exited 0 with a snapshot that failed to restore (chunk missing from blob map).
Fix (issue option b):
Deduplicate only against chunks held by a blob whose uploaded_ts is set (Chunks.ListInUploadedBlobs, used by loadKnownChunks).
At the start of every scan, drop blob rows with uploaded_ts IS NULL (their blob_chunks cascade) and any orphaned chunks, so the affected data is re-chunked and re-uploaded and a previously interrupted index is repaired.
The startup repair is load-bearing: CompleteSnapshot attaches any blob holding a referenced chunk, so a lingering un-uploaded blob would be exported and then missing at restore. The storage-less path marks its blobs uploaded in the same transaction that attaches them, keeping the invariant uniform.
Test: the reproduction is the TestBackupRetryAfterInterruptedUploadIsRestorable test from #72 (now on next) with its t.Skip removed; it fails without this fix and passes with it. This branch's earlier duplicate copy was dropped.
The interrupted metadata-export case (scenario 2 of #72) is split to #177.

An interrupted blob upload was silent data loss: the packer writes a blob's `chunks`, `blob_chunks`, and `blobs` rows to the local index before the upload is attempted (`internal/blob/packer.go`). If the upload failed, those rows survived, and the next run deduplicated against chunks whose data never reached storage, then exited 0 with a snapshot that failed to restore (`chunk missing from blob map`).
Fix (issue option b):
- Deduplicate only against chunks held by a blob whose `uploaded_ts` is set (`Chunks.ListInUploadedBlobs`, used by `loadKnownChunks`).
- At the start of every scan, drop blob rows with `uploaded_ts IS NULL` (their `blob_chunks` cascade) and any orphaned chunks, so the affected data is re-chunked and re-uploaded and a previously interrupted index is repaired.
The startup repair is load-bearing: `CompleteSnapshot` attaches any blob holding a referenced chunk, so a lingering un-uploaded blob would be exported and then missing at restore. The storage-less path marks its blobs uploaded in the same transaction that attaches them, keeping the invariant uniform.
Test: the reproduction is the `TestBackupRetryAfterInterruptedUploadIsRestorable` test from https://git.eeqj.de/sneak/vaultik/issues/72 (now on `next`) with its `t.Skip` removed; it fails without this fix and passes with it. This branch's earlier duplicate copy was dropped.

Duplicate, stale test after rebasing onto current next. next now includes the fault-injection tests from #72 (commit 6b7517a). Rebasing this branch onto it puts two test functions with the identical name TestBackupRetryAfterInterruptedUploadIsRestorable into the internal/vaultik test binary: internal/vaultik/fault_injection_test.go:358 (from #72) and internal/vaultik/interrupted_upload_test.go:62 (this PR). The #72 copy still reads t.Skip("blocked on https://git.eeqj.de/sneak/vaultik/issues/148 ..."), but this PR closes#148 -- the suite now ships a skipped test citing a resolved issue plus a duplicate name a newcomer cannot disambiguate in one reading. The definition of done on #148 (item 3: "Remove the t.Skip from TestBackupRetryAfterInterruptedUploadIsRestorable and have it pass") is now concretely satisfiable and left unmet.
Acceptable: reconcile with #72 now that it is on next -- either delete this PR's new copy and un-skip the #72 test (satisfying #148 item 3), or remove #72's now-stale skipped copy, so a single, un-skipped reproduction remains. The suite must not carry two identically named tests, nor a t.Skip pointing at the issue this PR closes.
Disclosure: this arose because next moved (#72 merged) after the PR was finalized; the remedy is small but required to gate against current next.

An interrupted blob upload left the blob's chunks, blob_chunks, and
blobs rows committed before the upload was attempted, so a later run
deduplicated against data that never reached storage and produced a
snapshot that reported success but could not be restored.
Fix (issue option b): a chunk counts as known only when a blob holding
it has uploaded_ts set, and each run drops un-uploaded blob rows and the
chunks they orphan at startup, so the affected data is re-chunked and
re-uploaded. A blob recorded with no remote backend is marked uploaded
so the invariant holds uniformly.
The reproduction is issue #72's interrupted-upload test: its t.Skip is
removed and it passes against this fix, and this branch's earlier
duplicate copy of it is dropped.
The interrupted metadata-export case is split to follow-up issue #177.

Removed the t.Skip from that test in internal/vaultik/fault_injection_test.go (the copy from #72); it now runs and passes against the production fix. Kept this one rather than the branch's own: it lives in the shared fault-injection suite and drives the same path — blob uploads failed through the faultstore seam, retried on the same index, restored byte-for-byte — which satisfies done-item 3 of #148.

The PR description misdescribes the reproduction after the rebase onto current next. It still reads: "The skipped test named in the issue lives in the unmerged branch for #72, so this adds its own reproduction." That is no longer true. #72 is merged -- it is this branch's parent commit (6b7517a) -- the branch's own added copy internal/vaultik/interrupted_upload_test.go was deleted in the rework, and the reproduction now relied on is issue #72's TestBackupRetryAfterInterruptedUploadIsRestorable in internal/vaultik/fault_injection_test.go with its t.Skip removed. The landing commit message and the most recent comment already state this correctly; only the description was left stale, so a reader is told the PR adds a reproduction it does not add and that #72 is unmerged when it is on next. Acceptable: rewrite that sentence to say the reproduction is issue #72's test with the skip removed (matching the commit message), and drop the "adds its own reproduction" parenthetical.
The PR description is 273 words, over the roughly 250-word limit. Acceptable: trim to about 250 words or fewer while keeping the fix summary and the test statement.
