redirector: Rust host on vendored OpenSSL; shared typed config extracted
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.

openfut-blaze-host: thin Blaze sidecar, live-parity with Python
Third migration step, and the one that turns fixture parity into transport parity. A TCP host that frames a Fire2 stream, keeps one Session per connection, calls openfut-adapter-fifa17::dispatch(), and writes the returned frames in order. It owns a socket, a buffer, a session and diagnostics -- that is the complete list. No coins, club, packs, profiles or UTAS logic: those belong to Core, reached through the adapter later. NO TLS, and that is evidence-based rather than an omission. The Blaze main port is plaintext: sending a raw Fire2 Util::ping to the running backend returns a plaintext PingResponse, blaze_handle uses the raw socket, and only redir_handle wraps ssl. TLS belongs to the redirector phase. LIVE A/B AGAINST THE RUNNING PYTHON BACKEND: 101 frames across three conversations, identical normalized traces. This is the first result in the migration that is not purely offline. check-live-parity.sh replays the recorded conversations against both endpoints over real sockets and diffs volatile-masked traces; session keys and clocks are masked, so anything that differs is behavioural. Transport tests cover what fixtures cannot: byte-for-byte replay over a socket, requests dribbled one byte at a time, several requests in one write, the four-frame login burst ordered on the wire, session state persisting across frames and NOT leaking between connections, an absurd payload length closing the connection instead of allocating, and an undecodable body still getting a reply. 18 tests here, 116 across the three migration crates. MUTATION TESTED, including the comparison itself. Dropping a post-login notification is caught by the probe (frame count) AND the diff; a same-length content change deep inside a notification body (CTY "US"->"GB", payload 116 both sides) is caught ONLY by the trace digest. So the probe's exit code is not the test -- the diff is, and the README says so. check-live-parity.sh was itself verified to exit 1 under mutation. The listen port is required configuration with no default, so the sidecar cannot silently collide with the working container. OPENFUT_BIND stays the advertised-config bind (the adapter derives nucleusConnect from it, reproducing the oracle) and the listener gets its own setting, so the two are not conflated. Gates 1-4 pass and are re-runnable. Gates 5-10 need a FIFA client and are listed in the README, including the Python -> Rust -> Python -> Rust back-and-forth that proves the rollback path rather than asserting it. Python backend untouched and still the live runtime; contract suite 446/446 after this work. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

openfut-adapter-fifa17: FIFA 17 Blaze adapter, oracle-tested
The second migration step: the layer above the codec, deciding WHAT to say
rather than how to encode it. Sits on openfut-protocol-blaze and supplies
what that crate deliberately refuses to know.
blaze/ids.rs component/command/notification tables
blaze/config.rs injectable identity + endpoints, nothing hardcoded
blaze/session.rs per-connection state
blaze/client_config.rs the fetchClientConfig tables
blaze/responses.rs 16 Blaze::* response bodies
blaze/dispatch.rs (component, command) -> Vec<Frame>
Parity is tested, not asserted. fixtures/generate.py drives the real
blaze_responder_v3b.dispatch() and records 49 request->response(s)
transactions, replayed in order against a shared session per connection so
ordering-dependent behaviour is exercised: preAuth captures the locale later
ALOC fields echo, login sets the auth code getAuthToken returns. Comparison
is byte-for-byte including frame count and order.
98 tests green across both crates; clippy clean.
MUTATION TESTED, and it found a real defect in this commit's own design.
Swapping two post-login notifications and flipping one enum inside
AccountInfo both turned the suite red as intended. Hardcoding an address in
utas_base() did NOT -- the config templating substituted raw hosts directly,
making those helpers dead code that merely looked load-bearing. The table now
templates on URL-level tokens ({utas_base}, {nucleus_base},
{pow_content_url}) so they are the single place a URL shape is defined, and
the mutation is caught.
The client config table (227-243 rows per CFID) is generated from the oracle
rather than transcribed: it is reverse-engineered data, not logic, and 400
hand-copied string literals would add a typo class no reviewer can catch. The
generator substitutes real addresses back in and diffs against the oracle for
every section before writing, so the templating is verified rather than
assumed.
Reproduces one known defect deliberately: nucleusConnect is built from BIND,
not advertise, so the live split deployment tells a client on another machine
to reach Nucleus at http://0.0.0.0:42131. Confirmed against the running
container. Reproduced because it is what the only proven-working config does;
fixing it needs live validation and is a separate change. It also implies the
Nucleus stub is not reached in the current remote flow.
Blaze carries no FUT domain state -- no coins, packs, clubs or squads on this
wire -- so Session stays a session key, locale, service name, auth code and a
flag. That boundary will need defending when UTAS is migrated.
Not wired into anything. The crate answers frames; it opens no socket and
owns no runtime. The Python backend remains the live service and the oracle,
and is unmodified (contract suite still green).

openfut-protocol-blaze: generic Blaze protocol layer, oracle-tested
First Rust component of the Python -> Rust migration. Chosen first because
it is the lowest genuinely game-independent layer, it has an executable
oracle, and both existing Rust implementations of it are wrong.
Contents:
* fire2 -- the proven 16-byte frame header, frame/stream splitting
* heat2 -- tag packing, varints, all 11 TDF value types
* message -- frame + decoded body, routed by NUMERIC component/command
* diagnostics -- dumps for capture review
No FIFA 17 command tables, response schemas or notification IDs: this layer
knows 0x0009/0x0007 is component 9, command 7, not that it means
Util::preAuth. That mapping belongs to a game adapter, which is what lets a
future FIFA 18/23 adapter reuse this.
Parity is tested, not asserted. fixtures/generate.py drives the proven
Python responders (heat2.py, blaze_responder_v3b.py) and freezes 56 vectors
-- 31 of them real payloads from the responder's own builders, including
the 11.8 KB preAuth reply. tests/oracle_parity.rs replays every one
byte-for-byte. 54 tests green; clippy clean.
Supersedes two wrong framings, neither of which is removed yet:
* fifa-blaze/crates/blaze-proto/frame.rs -- a 12-byte header with a u16
length, nibble-packed type/options, an error field and a JUMBO flag.
A documented guess at FIFA 23 predating the FIFA 17 recon.
* heat2.py::build_fire2_frame -- packs >IHHHHB3s, msgId at [10:12] and
msgType at [12]. Dead code, but its docstring still states that layout.
Confidence is carried in the types: TypeId::is_verified() reports which
layouts are capture-backed (int/string/blob/struct) and which the oracle
marks UNVERIFIED (list/map/union/varlist/objtype/objid/float), with a test
asserting the unverified ones stay flagged.
Cargo.lock is deliberately NOT included: it re-resolves ~240 lines against
the current registry even without this crate, so that churn is pre-existing
and does not belong in a foundation commit.
The Python backend remains the live runtime and is untouched. Nothing
consumes this crate yet.
