feat(ltk_overlay): preserve original WAD signature when patching#170
Merged
Conversation
Brings in WAD signature checks and preservation plumbing (toc_sha256, verify_signature, prebuilt signature/checksum in the builder) needed by the upcoming ltk_sig crate. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Patched overlay WADs now carry the source WAD's header signature and checksum verbatim (via ltk_wad 0.3.0 accessors) instead of zeroed placeholders. The signature covers the original TOC, not the patched one - it is preserved as provenance so ltk_sig's merged-WAD verification can recover the Riot-signed original TOC from overlay files.
