[Python ssl / OpenSSL 3] SSLEOFError '[SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol' — peer/proxy closed TLS without close_notify; OpenSSL 3 reports it as an error

Cause (Documented platform behavior): OpenSSL 3.0 changed an unexpected transport EOF from SSL_ERROR_SYSCALL (return 0) to SSL_ERROR_SSL with reason UNEXPECTED_EOF_WHILE_READING; CPython maps both to SSLEOFError 'EOF occurred in violation of protocol'. ssl.OP_IGNORE_UNEXPECTED_EO

[coremltools] "When 'convert_to' is neuralnetwork, the minimum deployment target must be at least ..." / "'convert_to' cannot be ... It must be 'mlprogram'" - target/format mismatch

Cause (Documented platform behavior): mlprogram requires iOS15+ targets; neuralnetwork cannot be used with iOS15+ targets. Fix status: documented_behavior Other error fragments: - the minimum deployment target must be at least iOS15/macOS12/watchOS8/tvOS15 Evidence (public source

[websockets (Python)] Large realtime/audio/base64 messages fail: PayloadTooBig 'frame with N bytes exceeds limit of 1048576 bytes' and connection closed with 1009 (message too big) — default max_size…

Cause (Documented platform behavior): websockets.asyncio.client.connect defaults max_size=2**20; frames above it raise PayloadTooBig ('frame with N bytes exceeds limit of M bytes') and the protocol fails the connection with CloseCode.MESSAGE_TOO_BIG (1009, 'message too big'). Fix

[Go crypto/x509] 'x509: certificate signed by unknown authority' persists on macOS/Windows despite SSL_CERT_FILE/SSL_CERT_DIR — env vars only apply on Linux/BSD; Go uses the platform verifier there

Cause (Documented platform behavior): root_unix.go (which reads SSL_CERT_FILE and SSL_CERT_DIR) is compiled only for aix, BSDs, linux, solaris, js/wasm, wasip1. On windows/darwin/ios, verification with system roots delegates to the platform verifier, so trust must be in Keychain

[websockets (Python) realtime/live APIs] 'ConnectionClosedError: sent 1011 (internal error) keepalive ping timeout; no close frame received' — 20 s ping_timeout exceeded because of latency or a block…

Cause (Documented platform behavior): websockets' keepalive task waits ping_timeout for the pong and on timeout fails the connection with CloseCode.INTERNAL_ERROR (1011) and reason 'keepalive ping timeout'. The FAQ attributes it to excessive latency (poor connectivity or more tra

[Node.js NODE_EXTRA_CA_CERTS] Custom CA silently not applied: set via process.env at runtime (ignored), overridden by an explicit 'ca' option, ignored for setuid/capabilities; bad path only emits 'Wa…

Cause (Documented platform behavior): Node reads NODE_EXTRA_CA_CERTS only when the process first launches; changing it at runtime has no effect. When a TLS/HTTPS client passes 'ca' explicitly neither well-known nor extra certs are used. A missing/malformed file only triggers a

[coremltools] "The specification has version N but the Core ML framework version installed only supports ... version M or older" - deployment target newer than host macOS

Cause (Documented platform behavior): Core ML framework supports up to a spec version per OS release. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/apple/coremltools/db4dd46b64dcaa4c6

[coremltools] "Unable to load CoreML.framework. Cannot make predictions." / "Failed to load _MLModelProxy" - predict() on Linux/Windows or broken native lib

Cause (Documented platform behavior): Prediction requires the Core ML framework on macOS; the native proxy import failure is only logged as a warning at import. Fix status: documented_behavior Limitations: - Python-version wheel mismatch as cause is inferred. Other error fragment

[Go net/http HTTP/2] 'http2: server sent GOAWAY and closed the connection; LastStreamID=N, ErrCode=NO_ERROR, debug=""' and 'http2: client connection lost' (ping timeout) on long-lived connections

Cause (Documented platform behavior): When the connection's read loop ends with EOF/net error after a GOAWAY, the transport reports http2GoAwayError with LastStreamID, ErrCode and debug data; closeForLostPing closes the connection with 'http2: client connection lost' and interrup

[optimum-onnx] "Trying to export a X model, that is a custom or unsupported architecture, but no custom onnx configuration was passed as `custom_onnx_configs`"

[Vercel AI SDK streamText] No exception but empty output / AI_NoOutputGeneratedError "No output generated. Check the stream for errors." — errors become stream parts

Cause (Documented platform behavior): streamText starts streaming immediately and turns errors into stream parts instead of throwing; when no step was recorded the result promises reject with NoOutputGeneratedError. Fix status: documented_behavior Evidence (public sources, summar
