## Summary - bound Arrow-backed metric string cells to 32,700 UTF-8 bytes - encode directly into a fixed-size buffer and stop at a valid character boundary - add an oversized-value contract for the metrics builder ## Validation - `./mvnw -pl hertzbeat-common-core -Dtest=CollectRepTest test -DskipITs -Dsurefire.failIfNoSpecifiedTests=false -DfailIfNoTests=false` - `git diff --cached --check` AI assistance: used for draft implementation and test iteration. Human validation: the focused Maven module completed successfully; all 3 CollectRep tests passed and Checkstyle reported no violations. Risk notes: string metric values longer than 32,700 UTF-8 bytes are truncated before Arrow storage; shorter values retain their existing representation. -- This is an automated message from the Apache Git Service.
