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.

- 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
- Bump chainlink-stellar and bindings pins to the regenerated
  batch bindings in all four modules
- Data ids are now 32 opaque bytes: widen the feature helpers
  and the test fixture, drop the wire-id zero padding
- Read via batch LatestRound and unwrap the single entry

- Guard a zero scheduled execution time, which the cache would
  silently drop as stale, and split the data id hex errors so
  the length case no longer prints a nil decode error
- Return an error for a missing forwarder instead of panicking
- Fold the vestigial error-message block onto the proto getter
- Assert round id and timestamp alongside the answer
- Rename helpers to package conventions, drop restating doc
  comments, convert report tests to require
