Conversation
Ships parse_tdx_quote_signature() and TdxQuoteSignature so cmcp and ca2a can delegate the DCAP v4 layout instead of each carrying its own copy of the offsets. Both currently have the flat-parse bug that reads the QE report six bytes early and rejects every genuine quote, so this release is what unblocks fixing them by deletion rather than by a third hand-rolled parser. Also carries the v0.2 COSE envelope specification (#243 phase 1). No change to manifest signing or verification behaviour. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Publishes the shared TDX parser so cmcp and ca2a can stop carrying their own copies of the DCAP v4 offsets.
Why now
parse_tdx_quote_signature()landed in #247 but is unreleased, so neither sibling repo can consume it. Both still have the flat-parse bug it fixes:src/cmcp_verify/tdx.pysrc/ca2a_runtime/tee/tdx.pyandsrc/ca2a_verify/tdx.pyReal DCAP v4 quotes nest the QE material under a type-6
QE_REPORT_CERTIFICATION_DATAheader. A flat parse reads the QE report six bytes early and therefore rejects every genuine quote. Releasing this lets both repos fix it by deletion rather than by writing a third hand-rolled parser, which is what is happening on cmcp's in-flight branch right now.Contents
Added
parse_tdx_quote_signature()andTdxQuoteSignature, the hardware-validated DCAP v4 signature-section parse, written against a real GCP C3 quote (feat(tee): share the validated DCAP v4 signature-section parse #247)spec/agent-manifest-cose-envelope-v0.2.md, the v0.2 COSE envelope specification, ADR-0011 phase 1 (spec(cose): specify the v0.2 COSE envelope (#243 phase 1) #248)Minor rather than patch: new exported API. No change to manifest signing or verification behaviour, and manifest version 0.1 is untouched.
Verification
python -m buildplustwine check: both artifacts PASSED for 0.7.0After merge: tag
python-v0.7.0for the OIDC publish, then confirm from the installed PyPI package before touching the sibling repos.
