🩹 Four Targeted Fixes

A quick patch release fixing a critical fetch behavior and three smaller issues discovered in the first 24 hours of Serve V2.

☄ fetch: 4xx/5xx Now Fails Properly

This was the kind of bug that makes you question everything. Before this fix, a fetch: task that hit a 404 or 500 would silently succeed — returning the error body as the task output. Your downstream tasks would happily process an HTML error page as if it were real data.

# Before v0.58.1: this silently "succeeded" with the 404 HTML body
- id: get_data
  fetch: "https://api.example.com/missing-endpoint"
  # Output: "<html><body>404 Not Found</body></html>" 😱

# After v0.58.1: this correctly fails with a fetch error
- id: get_data
  fetch: "https://api.example.com/missing-endpoint"
  # → NIKA-045: HTTP 404 Not Found

The exception is response: full — if you explicitly ask for the full response, you get status + headers + body regardless of status code. That's by design for APIs where error responses contain useful data.

🔧 Other Fixes

  • DAG flow edge case — Certain graph topologies with diamond-shaped dependencies could produce incorrect execution order. The DAG scheduler now resolves these correctly.

  • LSP compiler warning — Unused import in nika-lsp crate removed. Clean cargo clippy across the workspace.

  • wiremock test reliability — Cleaned up flaky test assertions and matching patterns in integration tests. Tests that relied on response ordering are now order-independent.
