### Purpose The bloom filter file index reads `items` and `fpp` from table options with no bounds. A percentage-shaped `fpp` like `10` makes every write fail with a bare `NegativeArraySizeException`; `fpp = 0` overflows the same way; `fpp = 1` or negative silently builds a one-byte filter that prunes nothing; a large `items` overflows the bit-set size. Reject `fpp` outside `(0, 1)` and non-positive `items` in the writer (the read path never consults them, so existing tables stay readable), and guard the bit-count overflow in `BloomFilter64`. A bad option now fails at write time naming it. Mirrors #9765 for range-bitmap `chunk-size`. ### Tests `BloomFilterFileIndexTest.testRejectsInvalidOptions`: `fpp` = 10 / 0 / 1.0 / -0.1, `items` = 0, `items = Integer.MAX_VALUE`, plus a valid config. Fails on master, passes here. Written with Claude Code; verification is mine. -- This is an automated message from the Apache Git Service.
