   Thanks @SEZ9 for the follow-up, and @goutamadwant for your patience. I can 
now close the CI question I left open in my review, because the fork run is 
readable.
   
   I earlier guessed that an existing test might assert the old, under-counted 
byte values. That guess was wrong. The fork run for head `3f4f7ff11c` (Build -> 
run 39008515550) has exactly one failing job, `engine-v2-it (11, 
ubuntu-latest)`, and exactly one failing test:
   
   ```text
   
BackpressureSlowSinkIT.testCheckpointsKeepCompletingUnderSustainedBackpressure:247
   expected at least 3 additional checkpoints to complete during the 90s 
sustained backpressure window, only observed 2
   (samples=[1, 1, 1, 2, 2, 2, 3, 3, 3])
   ```
   
   That test is about checkpoint scheduling under a slow sink, and it does not 
touch `SeaTunnelRow` byte accounting. The same checkpoint-lock-starvation flake 
is already tracked in #12316 and #12313, and neither is merged to `dev` yet, so 
syncing `dev` will not clear it. My read is that this failure is unrelated to 
this PR. That is an inference from the test name, the assertion and the open 
tracking PRs, not something this PR's diff can influence.
   
   One more thing to know: when that job failed, GitHub cancelled the rest of 
the run. The other jobs (`all-connectors-it-*`, `jdbc-connectors-it-*`, 
`kafka`, `iceberg` and others) show as cancelled, not passed. So the Build is 
red, but a clean run has not yet exercised those jobs against this change.
   
   Suggested next step for the author: use "Re-run failed jobs" on that fork 
run (or push a sync with `dev`, which also triggers a fresh run). If 
`BackpressureSlowSinkIT` is the only red job again, it can be treated as the 
known flake. If any other job fails, please paste the job and test name here 
and I will look at it.
   
   This does not change the source-side picture from my review: no blocking 
issues in the code. The compatibility note in the PR description that @SEZ9 
asked for is still a nice-to-have.
