CatchBench
Copyright (c) 2026 Yue Zhao

This distribution contains normalized material derived from third-party sources and retained model
output generated from those sources. Exact files, upstream projects, source identifiers, licence
status, and unresolved blocks are recorded in THIRD_PARTY_LICENSES.md and ASSET_MANIFEST.json.
Each source identifier is typed there as an immutable revision or as a mutable identifier, because
an n8n template ID and a SWE-bench submission label name a location whose content can change rather
than fixed bytes.

The redistributed licence texts travel with this repository rather than by link. Apache-2.0,
GPL-3.0, and CC-BY-4.0 read the same for every project declaring them, so one copy of each covers
every record: third_party/licenses/Apache-2.0.txt, GPL-3.0.txt, and CC-BY-4.0.txt, indexed with
their SHA-256 digests and the projects they cover in third_party/licenses/CANONICAL-TEXTS.md. MIT
names the copyright holder, so its notices are per project: the CrewAI and MCP notices are under
third_party/licenses/, and the InjecAgent and Who&When code-project notices are reproduced inline in
THIRD_PARTY_LICENSES.md. Records marked NOASSERTION, Other, or unverified declare no licence at all
and remain unfinished. Five further projects declare MIT or Apache-2.0, but their pinned licence
file could not be retrieved; each is marked UNRESOLVED where its notice would be, and the 6 records
derived from them remain unfinished. CatchBench's MIT licence does not override any source terms.

The following upstream NOTICE text accompanies MCP-derived records. It is reproduced verbatim;
references to LICENSE within these blocks mean the pinned upstream LICENSE files identified in
THIRD_PARTY_LICENSES.md, not CatchBench's root LICENSE.
