-orbisRPC - BUILD SETUP
-=====================
-
-Working build command (copy/paste):
-
-    cd path to project
-    PS4_SDK_SRC=$HOME/ps4-payload-sdk-src \
-    PS4_PAYLOAD_SDK=$HOME/ps4-payload-sdk \
-    ./scripts/build_sdk.sh
-
-Output: build-sdk/orbisrpc_sdk.elf  (~2,237,856 bytes)
-
-Both env vars matter. PS4_PAYLOAD_SDK says where the compiler is;
-PS4_SDK_SRC enables the 13.52 firmware gate described below.
-
-
-ONE-TIME SDK SETUP
-------------------
-
-The ps4-payload-dev SDK must be built from git, NOT from the release ZIP.
-Run this once per machine:
-
-    cd path to project
-    ./scripts/build_sdk_from_source.sh
-
-That clones to ~/ps4-payload-sdk-src, pins commit 573b4a0, and installs to
-~/ps4-payload-sdk.
-
-WHY NOT THE RELEASE ZIP:
-
-    The SDK's crt/patch.c holds a per-firmware table and __patch_init()
-    returns an error for any firmware not in it. crt/crt.c propagates that
-    out of _start(), which calls payload_terminate() and never reaches
-    main(). Silent death - no log line, nothing to diagnose.
-
-    Release v0.9 (2026-05-12) lists 13.50 but not 13.52. The 13.52 offsets
-    landed on master in 959e4ed (2026-06-25) and have never shipped in a
-    release. A payload linked against the ZIP cannot boot on 13.52.
-
-If the SDK is missing:
-
-    ./scripts/build_sdk.sh    ->  "FAIL: .../orbis-clang not found"
-
-Both scripts verify the SDK source supports 13.52 before building, so a
-too-old SDK fails at build time with a clear message instead of producing a
-payload that dies on the console.
-
-To move to a newer SDK commit later:
-
-    PS4_SDK_REF=<commit> ./scripts/build_sdk_from_source.sh
-
-
-REQUIREMENTS
-------------
-
-    WSL2 (all commands below run in WSL, not PowerShell)
-    git
-    clang-18 + lld-18     (llvm-config-18 or llvm-config must be on PATH)
-
-Ubuntu packages:
-
-    sudo apt install git clang-18 lld llvm-18
-
-The SDK also expects an llvm shim on PATH. build_sdk.sh adds $HOME/llvmshim
-itself; if your setup differs, that line in scripts/build_sdk.sh is where to
-look.
-
-Repo location matters: scripts assume you run from the repo root, because
-they reference relative paths like orbisrpc/ and third_party/.
-
-
-VERIFYING THE BUILD
--------------------
-
-    ls -la build-sdk/orbisrpc_sdk.elf
-
-A good build prints no FAIL lines and ends with the elf listing. Two lines
-are normal and not errors:
-
-    "note: PS4_SDK_SRC not set, skipping the 13.52 SDK firmware gate."
-    (only appears if you omitted PS4_SDK_SRC - always pass it)
-
-To rebuild from scratch:
-
-    rm -rf build-sdk && ./scripts/build_sdk.sh
-
-
-HOST TESTS (optional, fast - no console needed)
-
-    make -C tests all
-    ./tests/test_utils
-
-Known pre-existing failure, NOT a regression:
-
-    test_appdb: Assertion `rc == SQLITE_OK' failed
-
-The system sqlite3 library on the host differs from the bundled amalgamation
-(rc=14). Tests registered before test_appdb in main() do run and pass.
-
-
-SENDING IT TO THE CONSOLE
--------------------------
-
-GoldHEN BinLoader on port 9020. Arm it in the exploit host menu, then send
-the payload in ONE connection. Never probe the port first - any empty connect
-burns the arm and the real payload then arrives at a dead listener:
-
-use netcat e.g nc console_ip 9090 < payload.elf
-
-Then confirm it ran - within ~20 seconds:
-
-    curl -s ftp://<console-ip>:2121/data/orbisRPC/log.txt
-
-Expected first line: "orbisRPC payload boot"
-
-No log file at all means the payload never executed. Do not debug the daemon
-until you see that line. See docs/injecting.md for elfldr (port 9021) and
-other methods.
