Summary

  • End to end test proving the CRE write path into the Stellar data feeds cache: a workflow DON produces a signed report, the Soroban forwarder verifies it, the cache stores the answer, and the test reads it back through the generated bindings.
  • Adds a data feeds write workflow module, cache deploy and configure helpers in the stellar feature, and a fourth subtest in the stellar suite.

Context

Aptos and EVM already have data feeds e2e coverage; Stellar had only the core capability tests (reads plus a write to a dummy receiver). The upstream chainlink-stellar stack now ships the audited cache contract, generated Go bindings, and embedded wasm artifacts, which is everything needed to exercise the real product path locally.

- Pin chainlink-stellar and bindings to the embedded artifacts commit
- Deploy and configure the data feeds cache via the stellar feature
- New datafeeds/write workflow encoding report entries in-workflow
- Assert the answer lands on-chain by polling the cache latest_round
