Checked the other same-topic concurrency paths. I found and fixed two related windows: concurrent partial ALTER TOPIC requests could both build from one stale snapshot and overwrite each other, and overlapping owner transfers could share the renewal-block entry and unblock it too early. Commit 22c743be85a now serializes client alterations per topic (different topics remain concurrent) and rebases the attribute delta after the procedure acquires the subscription lock. The new persisted procedure variant keeps the old embedded serialization format compatible. Added lock, rebase, and serialization coverage; the focused ConfigNode tests pass (11/11). -- This is an automated message from the Apache Git Service.
