Retain bounded FAT and offset-tagged PE observations through archive hashing, classification, and content nodes. Preserve PyInstaller member paths according to the observed carrier dialect and share APK v1 signing-name semantics. Read SQLite's implicit sqlite_schema table without inventing a stored schema declaration. Distinguish unsupported ELF numbering and decoded-name admission from malformed data and fixed scan allowances. Preserve Sigrok basenames and classify matching explicit input-format refusals at their owning boundary. Validation: 554 distinct tests passed, 3 skipped across serial focused runs; build, typecheck/lint, docs, formatting, and discovery (2141 files) passed. Sigrok command-boundary simulators do not establish real-tool decoding. Small repeated public PyInstaller CLI runs had equivalent inventory facts; warm median elapsed 0.5431s before / 0.5426s after, with no speed claim.
