Fission

Fission Wiki

Welcome to the operational and tutorial documentation for Fission: tasks, workflows, onboarding, and troubleshooting.

Canonical contracts (architecture, CLI flags, evaluation procedures, changelog) live in the main repository and are linked from each wiki page—do not treat the wiki alone as the source of behavioral truth.

For how repository docs and wiki relate, see Documentation Hub.

What Fission is

Fission is a Rust-native reverse-engineering and decompilation workspace built around:

• Sleigh-based instruction semantics and lifting
• Rust-owned normalization from low-level IR toward NIR / HIR
• Graph-based, deterministic structuring
• Pseudocode rendering with a CLI-first product surface (fission-cli), plus an optional desktop UI (fission-tauri)

For supported formats and maturity, see the repository README.

Scope boundaries (wiki vs repository)

• Wiki pages stay short, task-oriented, and operational.
• Do not duplicate normative contracts; link to docs/ and code instead.
• Command-line behavior must match docs/CLI.md; when in doubt, trust the repo.
