funman300 fe2e531b0c fix(seasons): derive the FUT web-file base from openfut.cfg, not a lab IP 
`STAGING_FUT_BASE` hardcoded `http://10.10.0.120:8110/fut/` into the hook
binary, so the base-supply rewriter only worked on one machine and could not be
merged.

The prefix now comes from the same `openfut.cfg` / `openfut-common` source of
truth as every redirect target: `fut_content_base()` builds
`http://<host>:<fut_content_port>/fut/` from the configured host.
`OpenFutPorts` gains `fut_content` with a named default
(`default_ports::FUT_CONTENT = 8110`) and an optional `fut_content_port=` key,
matching how every other OpenFUT port is already handled. A cfg written before
the key existed still parses and takes the default — failing it would disarm the
network redirect too.

Arming fails SAFE: an absent or unusable config arms nothing and the rewriter
leaves every url exactly as the client built it, rather than pointing it at a
guessed host. This also adds the `openfut-common` dependency to the hook on this
branch; main already has it.

Proof: the cross-built artifact no longer contains the string 10.10.0.120
(previously compiled in), openfut-common is green at 16 tests including the new
config-derived-base and backward-compatibility cases, and the launcher builds.

funman300 c3d41153be wip(seasons): offline-Seasons base-supply URL rewriter + VEH crash logger 
RETAINED DIAGNOSTIC WIP (pre-existing, brought forward, NOT production-ready).
Rewrites bare WEBFILE relpaths to a season content base and adds a vectored
crash logger used during offline-Seasons RE. Contains a HARDCODED staging
base (http://10.10.0.120:8110/fut/) \u2014 must be env-parameterized before any
promotion to main. Kept on this wip branch so main stays clean.

//! FIFA 17 in-process TLS/certificate + store crash-guard compatibility.
//!
//! Ports the *proven* subset of the external `openfut-autopatch` patch set into
//! `version.dll`, so the client-local contract no longer needs an external
//! `/proc`-writing patcher. Two concerns, both fail-closed and one-shot:
//!
//! 1. ProtoSSL certificate gates in FIFA17.exe (REQUIRED_FOR_TLS) — let the
//! TLS handshake against the OpenFUT bridge cert succeed. Present only after
//! the STEAMPUNKS packer maps/decrypts the real code, so they are polled for.
//! 2. The empty-"My Packs" store resolver crash-guard in CardsDLL
//! (REQUIRED_FOR_STORE_TLS, bug 6c) — CardsDLL loads lazily on entering UT,
//! so it is applied once the module appears.
//!
//! Deliberately NOT ported: the eight unconditional `STORE_PATCHES` from the
//! external patcher. They carry no recovered original bytes (cannot be
//! fail-closed) and are re-applied every tick (would require the very
//! constant-rewrite loop this milestone forbids); the external patcher's own
//! source records no rationale for them. See the Vault ADR.
//!
//! Every address is ASLR-relocated from its preferred image base at runtime
//! (`live = module_base + (static_va - preferred_base)`); nothing patches an
//! absolute address. Every write goes through [`crate::patch_mem`]'s fail-closed
//! primitive: original → write+verify, already-patched → no-op, anything else →
//! logged and skipped.

//! Passive, behavior-preserving diagnostic traces for FIFA 17's FUT pre-match

//!
//! RE (2026-08-20, Ghidra on CardsDLL_Win64_retail.dll) established that the
//! pre-match kit selector is fed ENTIRELY client-side (NOT by POW/EASFC):
//!
//! * `FUT_GET_MATCH_KITS_DP` (id 0x7565) builder `FUN_1800be6a0` (rva 0xbe6a0)
//! reads a boolean gate `ctx+0x152` (`KITS_AVAILABLE`); when false, or when
//! the two available-kit vectors are empty, the selector renders blank/white.
//! * The available home/away kit-id lists live on `FutSquadServiceImpl`
//! (`this+0xe08` home, `this+0xe38` away) and are written by the setter
//! `FUN_180196760` (rva 0x96760, vtable slot 0x1d0): args (this, srcVec, side).
//! * A club KIT ITEM is turned into an available kit by `FUN_1801c3480`
//! (rva 0x1c3480): it reads item fields (`+0x4c==7`, `+0x60==4`,
//! `+0x5c`∈{101 home,102 away}, `+0x94` source teamid, `+0xba`
//! teamkittypetechid) and calls `FUN_1801c44b0` (rva 0x1c44b0) to clone that
//! team's kit rows from the CLIENT-LOCAL `teamkits` DB into the FUT club
//! (teamtechid 130000).
//!
//! These traces answer, in one operator-driven match, exactly WHERE the empty
//! selector originates: do kit club items reach the client (kit_item_clone), does
//! the clone into the FUT club happen (kit_db_clone), does the available list get
//! set non-empty (set_available_kits), and what does the selector finally read
//! (get_match_kits: KITS_AVAILABLE + count). Every trace is read-only: it logs,
//! then tail-calls the original through a trampoline. Copied prologues are whole,
//! position-independent instructions (the one rip-relative prologue uses the
//! relocating installer).

//! FIFA 17 Offline Seasons PMA completion compatibility repair.
//!
//! Retail-compatible main-menu Kick Off completes the PMA instructions state by
//! broadcasting event `1` through the mode-zero child's callback dispatcher. FUT
//! Offline Seasons reaches the same PMA UI state but its completed drill scenario
//! broadcasts event `5`, which returns the UI to state `0` and leaves the drill
//! active. This default-off repair intercepts that shared callback dispatcher and
//! rewrites only the fully identified Offline Seasons `5` to `1`, then calls the
//! original dispatcher so every native subscriber observes the working completion.

//! Milestone 0 — Blaze transport reachability observation.
//!
//! PURE LOGGING, NO NEW DETOURS. This module does not hook anything itself. It is
//! called from the three Winsock detours the hook ALREADY installs — getaddrinfo
//! (`hooks.rs`), connect/WSAConnect (`connect_hook.rs`) and ConnectEx
//! (`connectex_hook.rs`) — and, when armed, emits a single grep-friendly
//! `TRANSPORT_WATCH:` line per resolution/connect so we can answer one question:
//!
//! Does the FIFA 23 client attempt ANY Blaze-flavored transport activity across a
//! full menu+FUT session, or none at all?
//!
//! Everything here is READ-ONLY: we parse the hostname / sockaddr the game passed
//! only to describe it in the log. We never change a resolution result or a
//! connection target — that redirect logic lives in the detours themselves and is
//! untouched. The env kill switch `OPENFUT_TRANSPORT_WATCH=1` gates all output;
//! disarmed (default) this module is inert (each entry point returns immediately).
//!
//! Future-reference note (beyond-beginner, deliberately NOT done here): a
//! types-first design would model a `ConnectTarget` enum (Inet{ip,port} / NonInet /
//! Short) and a `TransportEvent` and route them through the `tracing` crate with
//! structured fields, instead of hand-formatting strings into a flat log file. That
//! buys machine-parseable logs and log levels. For a one-shot observation gate,
//! flat `write_log` lines that `grep` cleanly are the lower-ceremony choice.
