TLS DEPENDENCY, as directed: the openssl crate directly with the `vendored` feature. NOT native-tls. native-tls abstracts over whatever the platform provides; here the requirement is the opposite -- precise, evidenced behaviour for one legacy client -- which needs explicit control of the cipher list, protocol floor/ceiling and security level. Vendored so a distro libssl update cannot silently change whether FIFA 17 can connect. Scoped to this crate alone. Neither OpenFUT Core nor the generic protocol crates gain an OpenSSL dependency. CIPHERS driven by the captured retail ClientHello, not by generic legacy assumptions. The six RSA+AES suites it offers are enabled; RC4 and MD5 are deliberately NOT, even though the client offers them -- it already negotiates AES256-GCM-SHA384, so resurrecting RC4 for completeness would weaken the service for nothing. TLS 1.2 floor and ceiling, matching the observed client; the floor is not dropped to 1.0 pre-emptively because "the oracle permits it" is not "the client requires it". SECURITY LEVEL IS NOT LOWERED. Tried the default policy first, as directed, and OpenSSL 3.6.3 accepts static-RSA/AES without weakening. No SECLEVEL change was needed and none is applied; it remains overridable per-listener with evidence. CERTIFICATE: the proven Python redirector's material is reused, so the TLS implementation stays the only variable in an A/B. Verified RSA-2048, CN winter15.gosredirector.ea.com, cert/key modulus match; the key stays gitignored. SHARED CONFIG. New openfut-host-config is now the only crate that reads the environment, and both hosts resolve endpoints through it. Two hosts each parsing OPENFUT_ADVERTISE would be exactly the "separate helpers constructing endpoints from different sources of truth" the address audit forbids. VERIFICATION BY REAL HANDSHAKE, not by enumeration. The crate exposes no accessor for a context's configured suites at this version, which turned out better: the host now rehearses the retail handshake at startup with a client restricted to exactly FIFA's eight suites and REFUSES TO SERVE if it fails, so a cipher/version misconfiguration surfaces at boot rather than as an unexplained failure during a live gate. Gates 1-5 pass: TLS config unit tests; a FIFA-suite-only client negotiates TLSv1.2/AES256-GCM-SHA384; each enabled RSA+AES suite negotiable alone; an RC4-only client is refused; an ECDHE-only client is refused (proving no modern policy was silently inherited); a full HTTPS round-trip returns bytes IDENTICAL to the Python oracle's recorded response. Cargo.lock committed for reproducibility: openssl 0.10.81, openssl-sys 0.9.117, openssl-src 300.6.1+3.6.3 (OpenSSL 3.6.3). Updating openssl-src is NOT a routine bump -- it requires re-running the FIFA compatibility gates. Gates 6-14 need the retail client and are next.
