🚩 Pre-existing high-cardinality metric label: batch_size
The
batch_sizelabel used at lines 90 and 102 is an unbounded integer, which violates the repository's.cursor/rules/otel-metrics.mdcrule that explicitly listsbatchSizeunder "DO NOT use high-cardinality attributes: Unbounded integers". WhilebatchSizedefaults to 500 and is set once in the constructor, it is still technically unbounded (configurable viaPodCleanerOptions). This is pre-existing and untouched by this PR, but worth noting for a future cleanup pass since it creates a new time series for every distinct batch size value.(Refers to line 90)
