What

When CLAUDE_CODE_CLIENT_CERT and CLAUDE_CODE_CLIENT_KEY do not belong together, typically mid-rotation, the loader now logs "mTLS: Ignoring mismatched client cert/key pair" and keeps the previously loaded pair rather than installing a broken one.

Details
  • The pair is verified with Node's X509Certificate.checkPrivateKey, honouring CLAUDE_CODE_CLIENT_KEY_PASSPHRASE.
  • Certificate blocks are located with a new PEM block pattern, so a bundle containing several certificates is handled.
Evidence

mTLS: Ignoring mismatched client cert/key pair

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
