Yanisdje opened a new pull request, #1076:
URL: https://github.com/apache/flink-kubernetes-operator/pull/1076

   This fixes a bug where the last reconciled spec on the flink b/g deployment 
shows an updated spec even when the update failed.
   
   ## Summary
   - Move `setLastReconciledSpec()` to after `startTransition()` and 
`startSavepointRedeployTransition()` succeed, so it's not stamped if the 
transition fails
   - Previously, `lastReconciledSpec` was set before the transition call — if 
the transition failed or was later aborted, `lastReconciledSpec` reflected the 
new spec while the active child still ran the old one. Subsequent deploys would 
see no diff and fall into PATCH_CHILD (in-place upgrade) instead of a proper 
B/G transition
   - Add assertion in `verifySavepointFetchFailureRecovery` confirming 
`lastReconciledSpec` does not contain the failed spec change
   
   ## Context
   Slack thread: https://shopify.enterprise.slack.com/archives/C0ALAR1TLP8
   
   ## Test plan
   - [x] `verifySavepointFetchFailureRecovery` passes with new assertion
   - [x] Full B/G controller test suite passes (72 tests)
   
    Fixes Shopify/streaming-compute#882
