Summary

A 200 from /api/v0/add with no parseable Hash, or a Hash that is not a CID, no longer counts as a successful pin. The old fallback returned the locally computed raw CID, an address the backend never confirmed stored; above the chunk threshold that CID is not even a stored block, so every later cat on it failed permanently.

Motivation & context

pin_git_object took the last NDJSON line carrying a Hash and fell back to Cid::from_git_object_bytes(data) when none did. The add goes out with raw-leaves=true, so on Kubo a payload over 262144 bytes lands chunked under a dag-pb root and the whole-object raw CID is never a stored block. The fabricated CID landed in encrypted_blobs.cid, so get_encrypted_blob failed on every fetch of an affected envelope and mirrors retried it on each sync.

Re-opened from the fork branch so the repo's Code Quality check can run.

Closes #452

Kind of change

• Bug fix
• Feature
• Security fix
• Docs
• Tests / CI
• Refactor (no behavior change)
• Breaking or protocol change (issue required first)

What changed

• pin_git_object (gitlawb-node) errors on a 200 add response without a usable Hash, carrying a truncated body excerpt, and errors when the returned Hash does not parse as a CID. The returned Hash stays authoritative and is not compared against the locally computed raw CID, since above-threshold adds legitimately return the dag-pb root.
• The delaying_endpoint test fixture and the mock in api/repos.rs now return a real CID. The fixture had been relying on the fallback by answering 200 with an empty body, so the budget and timing tests were passing through the bug.
• Regression tests pin_git_object_rejects_a_200_without_a_hash and pin_git_object_rejects_a_malformed_hash.

How a reviewer can verify

cargo test -p gitlawb-node --bin gitlawb-node ipfs_pin

Both new tests fail against the old fallback and pass with the fix. The full gitlawb-node suite passes on this branch merged with current main.

Before you request review

• Scope is one logical change; no unrelated churn
• cargo test --workspace passes locally
• New behavior is covered by tests (required for fixes)
• cargo fmt --all and cargo clippy --workspace --all-targets -- -D warnings are clean
• Commit titles use Conventional Commits (feat(...), fix(...), docs(...))
• Docs / .env.example updated if behavior or config changed (or N/A)
• Checked existing PRs so this isn't a duplicate

Protocol & signing impact

• Touches DID / did:key, Ed25519 / RFC 9421 signatures, UCAN, ref certs, or P2P wire formats
• Discussed in an issue before implementation
• Backward-compatible with existing nodes and previously signed history

Notes for reviewers

I ran the gitlawb-node suite, not the whole workspace.

If a Hash-less 200 is meant to be a supported shape, this should instead pin down what the parser is allowed to accept.

Summary by CodeRabbit

• Bug Fixes
  • IPFS pinning now reports an error when a successful service response is missing a valid content identifier, rather than generating one from the request. This applies to both missing and malformed identifiers, so pinning results accurately reflect whether the service returned a usable identifier.

Walkthrough

pin_git_object no longer substitutes a locally computed CID when the IPFS add response lacks a usable hash. It returns an error for a missing or invalid CID. Pinning test responses now use valid CIDs.

Full details: Linked Issues check

Explanation

[#452] pin_git_object rejects responses without a usable Hash and invalid CIDs. It returns a valid backend CID without comparing it with a locally computed CID. Regression tests cover missing and invalid hashes.

Full details: Out of Scope Changes check

Explanation

[#452] The production change addresses the reported failure. The tests cover the failure and bounded errors. The fixture and mock updates supply valid CIDs for the new validation. The incremental diff was unavailable, but the whole-PR evidence supports this assessment.

the missing-`Hash` response excerpt. Preserve enough context to diagnose the

🟢 Thanks for the contribution. I do not see any actionable issues from my review.

Merge readiness

• CI: Required PR checks on head 99a9c661 are green, including fmt + clippy, test (stable), test (beta), build --release, and MSRV. Analyze (swift) and CodeRabbit were still pending when this review was drafted; they are not merge blockers for this Rust-only change once required checks stay green.
• Target branch: Branch is mergeable with current main (merge-base a23c81d); no conflict or stale-base risk identified for this diff.
• PR checklist: The author left cargo test --workspace unchecked while noting gitlawb-node coverage; workspace tests passed in CI on this head, so this is a documentation nit rather than a defect signal.
• Related work: Closes #452; supersedes the fork PR #453 series with the same fix plus mock/test hygiene on the org repo.

Notes (non-blocking)

• Regression tests assert is_err() only; tightening oracles (error message or forbidding Ok(local_raw_cid)) would harden against fallback regressions but is not required by #452’s stated contract.
• Legacy encrypted_blobs.cid rows poisoned under the old fallback are a data/ops follow-up outside this PR’s parsing fix.

🟢 Thanks for the contribution. I do not see any actionable issues from my review.

Merge readiness

• CI: Required test (stable) on head ef597a19 failed once on ipfs_pin::tests::discovery_record_elapsed_leaves_neither_row (db_bounded elapsed arm returned Ok(()) instead of Err(Elapsed)). That test is not in this PR’s diff; test (beta) on the same workflow run succeeded. Treat as likely flake or environmental timing until reproduced on a re-run or on main at the same commit — not evidence of a defect in the pin-response change. All other required checks on run 42155810064 were green, including fmt + clippy, build --release, and MSRV.
• Target branch: Mergeable with no conflict in the three-dot diff, but the branch is 2 commits behind live origin/main (317a155). Rebase before merge so the fix lands on current main (includes recent #477 / #527 work).
• Prior review: jatmn approved at 99a9c661 before the ef597a19 commit that bounds invalid Hash text in errors (CodeRabbit request). That follow-up is present on head; no remaining open automated comment on the changed hunk.
• Related work: Closes #452; org PR supersedes fork #453 with mock/test hygiene on Twigpine/node.
• PR checklist: cargo test --workspace remains unchecked in the template; workspace tests are otherwise exercised in CI when stable passes.

Notes (non-blocking)

• Regression tests use is_err() oracles only; tightening to forbid Ok(local_raw_cid) would harden against fallback regressions but is not required by #452’s quoted contract.
• Legacy encrypted_blobs.cid rows written under the old fallback remain an ops/data follow-up outside this parsing fix.
