russell@unturf.com ac82cff865 php-cluster: doctrine-orm-0001 + composer-0003 CWE-407 defects; count 668→670 
doctrine-orm-0001: ClassMetadata::addSubClass in_array O(S²) subclasses list HIGH
  - src/Mapping/ClassMetadata.php addSubClass() scans plain $subClasses list
  - addSubClasses($parent->subClasses) called in doLoadMetadata: O(S²) per class
  - Fix: parallel $subClassesSet hash for O(1) membership; 500x at S=1000

composer-0003: InstalledRepository::getDependents in_array O(P²) needles list MEDIUM
  - needles array grows during foreach($packages) loop, in_array scan 3 sites
  - $packagesFoundSet already exists for cycle-detection but needles is separate
  - Fix: add $needlesSet = array_fill_keys($needles, true), mirror growth; 1000x at P=1000

CLEAN — wasmer

Scanned 2026-03-29 for CWE-407 (algorithmic complexity).

Findings

  • lib/wasix/src/os/task/thread.rs — signals: Vec<Signal> with .contains(): POSIX signal space is 1–31 values; N is strictly bounded. Not actionable.
  • lib/package/src/package/volume/fs.rs — intermediate_directories and metadata_files are BTreeSet<PathBuf>. CLEAN.
  • lib/compiler-llvm/src/object_file.rs — visited: HashSet with insert() return value used as guard before recursion. Correct pattern. CLEAN.
  • All other contains() calls are on bitflags or string substring checks. CLEAN.

Result: No actionable CWE-407 defects.
