# Attributions

source2rosetta derives Source-2 gamedata — function signatures, vtable offsets, and the schema/RTTI surface —
from stripped Valve libraries. It could not exist without the decade of reverse-engineering, tooling, and
open documentation produced by the Counter-Strike / Source / Source-2 community. Much of the engine came in
name-stripped; the *names* — the catalogues, symbol dictionaries, gamedata files, and SDK dumps that let the
derived offsets and signatures be labelled meaningfully — came from the projects below. The initial seeds were
foundational: they are why this tool has anything to say.

This document credits that prior work. Where a project supplied a specific ingredient (a catalogue, a symbol
set, a technique, a format), the role is noted.

## Provenance

source2rosetta and everything it ships are derived **only from legitimately-public sources**: open-source
SDKs, Valve's own tracked game builds, community gamedata files, and published research. Leaked or otherwise
proprietary game source was **deliberately excluded** from the corpus and the naming pipeline — a clean-room
boundary kept so the tool and its outputs carry no tainted provenance. The derived facts themselves
(fingerprints, offsets, signatures) contain no third-party bytes.

## Binary function similarity research

source2rosetta identifies functions across builds by fingerprinting and nearest-history matching. That design
draws on the binary-code-similarity literature.

- Andrea Marcelli et al., **"How Machine Learning Is Solving the Binary Function Similarity Problem"**, USENIX
  Security 2022 (Cisco Systems), and the accompanying dataset/code
  [binary_function_similarity](https://github.com/Cisco-Talos/binary_function_similarity) (Cisco-Talos).
- Steven H. H. Ding, Benjamin C. M. Fung, Philippe Charland, **"Asm2Vec: Boosting Static Representation
  Robustness for Binary Clone Search"**, IEEE S&P 2019.
- Xiaojun Xu et al., **"Neural Network-based Graph Embedding for Cross-Platform Binary Code Similarity
  Detection"** (Gemini), CCS 2017 — via the "Genimi" re-implementation bundled under `refs/papers/Gemini`.
- Alexander Hermans, Lucas Beyer, Bastian Leibe, **"In Defense of the Triplet Loss for Person
  Re-Identification"**, 2017 — the metric-learning framing that was pressure-tested for the fingerprint match.
- Also consulted for failure-detection framing: **"SAFE: Multitask Failure Detection for Vision-Language-Action
  Models"** (arXiv:2506.09937).

## Knowledge from model training

The AI-assisted name-extrapolation pass — proposing names for functions no catalogue covers — relied on the
general knowledge of the assisting model (Anthropic's Claude) about Source-2 / CS2 engine conventions, the
Itanium C++ ABI, ELF, and Valve's naming patterns. That knowledge is itself distilled from publicly-available
open-source code and documentation — in large part the very community projects credited above. Proposed names
are always cross-checked against the derived RTTI/offsets, never trusted blind.
