drafts: trueWalkthroughThe index backfill CLI now defaults ChangesIndex backfill behavior
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Index backfill now recomputes by default and fails after waited-for runs with skipped tipsets, but RPC callers may still receive success for incomplete backfills. The changelog also overstates failure behavior for --no-wait, and skipped-run errors lack actionable detail; these issues should be addressed before merge.

- We can avoid a breaking change by making the
--recomputedefault totrue. This way, we also allow the consumer to not do it, for any reason, e.g., mentioned sync starving. - Does the backfill now fail or not on a missing receipt? I think that was the main issue; it silently failed with return code zero, thus it flew under @EclesioMeloJunior radar.

This is a breaking change; users that were applying the --recompute would find their command failing after this.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Qualify the non-zero exit claim for --no-wait.
--no-wait returns before the skipped-tipset check runs. A later skipped tipset cannot change that process exit status. State that the error applies when the command waits for completion, and direct users to index backfill-status for asynchronous failures.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Report a backfill-specific error when skips occur.
When last.skipped > 0, this produces assertion failed: last.skipped == 0. Include the skipped count in the error so the non-zero exit explains why the backfill is incomplete.
As per coding guidelines, add context when errors occur in Rust.
