Fix status: documented_behavior Limitations: - Derived from the published @qwen-code/qwen-code 0.24.6 bundle; not reproduced in this session. Other error fragments: - Every worker handshake to the daemon will fail UNABLE_TO_VERIFY_LEAF_SIGNATURE. - Every worker handshake to the daemon will fail INVALID_PURPOSE. - --tls-cert and --tls-key must be provided together (got only --tls- Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/@qwen-code/qwen-code/-/qwen-code-0.24.6.tgz#package/chunks/run-qwen-serve-IIXONFKO.js (official_docs, unknown, documented_behavior): TLS preflight builds gap messages: unheldSelfSignedLeaf (BEGIN TRUSTED CERTIFICATE not taken by NODE_EXTRA_CA_CERTS loader -> DEPTH_ZERO_SELF_SIGNED_CERT), leaf purpose defect -> INVALID_PURPOSE, broken PEM markers -> UNABLE_TO_VERIFY_LEAF_SIGNATURE, and requires --tls-cert with --tls-key.
