From senior Go developer review: C7 CRITICAL: pagePool data race (ntx.go) - Moved global pagePool[8] + pagePoolIdx into per-Index struct - Eliminates race condition across goroutines using separate indexes C8 CRITICAL: Page.data dangling pointer after remap (ntx.go) - remapFile() now clears pagePool data slices (pointed into old mmap) - Prevents segfault from stale mmap references C4 HIGH: pop() bounds check restored (thread.go) - Removed performance optimization that eliminated underflow detection - Stack underflow now produces clear error instead of index -1 panic C1 HIGH: intExpLen overflow on MinInt64 (value.go) - Added special case: MinInt64 returns 20 (length of -9223372036854775808) - Prevents -v overflow in negation C11 CRITICAL: GoTo ReadAt error handling (dbf.go) - ReadAt failure now returns error and sets EOF - Previously silently used stale record buffer (data corruption risk) C14 HIGH: LEN() inline missing Hash case (gengo.go) - Added _v.IsHash() → len(Keys) branch C15 HIGH: EMPTY() inline missing Date case (gengo.go) - Added _v.IsDate() && _v.AsJulian() == 0 check 82/82 stress PASS. 14 packages ALL PASS.
