Fix Windows path split in tester_v3_c parse_file_arg too

Fix tester_v3_c base-dir split on Windows paths

+# AGENTS.md — tinygltf v3 (C)
+
+TinyGLTF v3 C (`tiny_gltf_v3.h` + `tiny_gltf_v3.c` + `tinygltf_json_c.h`) is the
+mainline. Legacy v1/v2/v3-C++ code lives under `attic/` and is not built or
+tested.
+
+## Commands
+
+- Unit tests (C): `make -C tests all && make -C tests run`
+- CMake: `cmake -B build -DTINYGLTF3_BUILD_TESTS=ON && cmake --build build && ctest --test-dir build --output-on-failure`
+- Meson: `meson setup build && meson compile -C build && meson test -C build`
+- WASM/web demo (requires Emscripten SDK, default `~/work/emsdk`):
+  `make -C web && make -C web sample` — then open `http://localhost:8000` via `make -C web serve`
+- Fuzzers: `make -C tests/v3/fuzzer` (clang + libFuzzer)
+
+## Pre-push audit checklist
+
+Run **before every push**. Fix or unstage anything found; the audit must pass
+clean.
+
+1. **Working tree sanity**
+   - `git status --short` — no staged build artifacts, no surprise files.
+   - Never `git add -A` / `git add .`: stage only intended paths. The repo
+     root frequently contains untracked scratch files (`Fox.glb`,
+     `benchmark/synthetic_*`, `log*`, `.cache/`, `tests/v3/fuzzer/artifacts|corpus`,
+     stray `*.gltf`/`*.bin` files). Verify `git status` before staging.
+
+2. **Secret scan**
+   - `gitleaks detect --source . --no-banner -r /tmp/gitleaks.json`
+   - `~/local/bin/trufflehog git file://$PWD --no-update --only-verified`
+   - Both must report 0 real secrets. Known allowed finding: `B3G_LEFT_ARROW`
+     generic-api-key hits in `attic/examples/common/OpenGLWindow/` are false
+     positives (keyboard key constants).
+
+3. **No build artifacts or unwanted large binaries**
+   - `git ls-files -z | xargs -0 du -b | sort -rn | head -30` — review the top.
+   - Rule of thumb: nothing over ~1 MB unless it is a tracked, intentional
+     asset (e.g. `attic/tools/windows/premake5.exe`, `models/Cube/*.png`).
+   - Watch for: compiled executables, `*.wasm`/`*.exr`/`*.log`/`*.o`/`*.obj`,
+     generated `output.*`/`cloth*`/`sim*.bin`/`out_*.exr` files, and large
+     `.gltf`/`.glb` files. Small test/regression fixture `.gltf` files
+     (e.g. under `tests/`, `models/regression/`, `tests/v3/security/`) are OK.
+   - `web/tinygltf_v3.js`, `web/tinygltf_v3.wasm`, `web/Cube.glb` are
+     generated by `make -C web` and must stay gitignored (never commit them).
+
+4. **History is lean**
+   - If an unwanted file was added in an unpushed commit, rewrite it
+     (`git rebase -i origin/<branch>`, `git rm` + `--amend`) so the blob never
+     reaches the remote, then `git gc --prune=now` locally.
+   - Push only intended branches (`git push origin <branch>` — never `--all`
+     or `--force` unless explicitly asked).
+
+5. **Final smoke check**
+   - `make -C tests run` passes (all 4 testers).
+   - If touched: `cmake`/`meson` builds and `make -C web` still succeed.

-# Header only C++ tiny glTF library(loader/saver).
+# tinygltf v3 — C glTF 2.0 loader/saver

-`TinyGLTF` is a header only C++11 glTF 2.0 https://github.com/KhronosGroup/glTF library.
+`TinyGLTF v3` is a C11-first implementation of a glTF 2.0
+https://github.com/KhronosGroup/glTF loader and writer.

-`TinyGLTF` uses Niels Lohmann's json library (https://github.com/nlohmann/json), so now it requires C++11 compiler.
-(Also, you can use RadpidJSON as an JSON backend)
-If you are looking for old, C++03 version, please use `devel-picojson` branch (but not maintained anymore).
+- **Pure C POD API** (`tiny_gltf_v3.h` + `tiny_gltf_v3.c` + `tinygltf_json_c.h`) — no STL, no RTTI, no exceptions required; easy to bind to other languages.
+- **Arena-based memory management** — all parse-time allocations come from a single arena; a single `tg3_model_free()` frees everything.
+- **Structured error reporting** — `tg3_error_stack` provides machine-readable errors with severity levels and source locations.
+- **Custom JSON backend** — `tinygltf_json_c.h` is a locale-independent pure-C JSON parser/serializer used by the v3 runtime.
+- **Streaming callbacks** — opt-in streaming parse/write via user-supplied callbacks.
+- **Opt-in filesystem and image I/O** — `TINYGLTF3_ENABLE_FS` / `TINYGLTF3_ENABLE_STB_IMAGE` are off by default; you control when and how assets are loaded.
+- **C++20 coroutine facade** (optional, auto-detected). C17/C++17 default.
+- **Hardened against untrusted input** — URI sanitization, post-parse index-bounds validation (default-on, opt-out via `tg3_parse_options.validate_indices = 0`), strict numeric range checks; exercised by a libFuzzer harness. See the `Security Considerations` block at the top of `tiny_gltf_v3.h`.
+
+## Quick start
+
+Copy `tiny_gltf_v3.h`, `tiny_gltf_v3.c`, and `tinygltf_json_c.h` to your project.
+Compile `tiny_gltf_v3.c` as C11 or newer. Define `TINYGLTF3_ENABLE_FS` when
+building `tiny_gltf_v3.c` if you want `tg3_parse_file()` to use stdio-backed
+filesystem helpers. The legacy `TINYGLTF3_IMPLEMENTATION` include path remains
+available for compatibility.
+
+```c
+#include "tiny_gltf_v3.h"
+```
+
+Loading a glTF file:
+
+```c
+tg3_parse_options opts;
+tg3_error_stack errors;
+tg3_model model;
+
+tg3_parse_options_init(&opts);
+tg3_error_stack_init(&errors);
+
+tg3_error_code err = tg3_parse_file(&model, &errors, "scene.gltf", 10, &opts);
+if (err != TG3_OK) {
+    for (uint32_t i = 0; i < errors.count; i++) {
+        fprintf(stderr, "[%d] %s\n", (int)errors.entries[i].severity,
+                errors.entries[i].message ? errors.entries[i].message : "(null)");
+    }
+}
+// ... use model ...
+tg3_model_free(&model);
+tg3_error_stack_free(&errors);
+```
+
+## Testing & verification
+
+The v3 C runtime ships with three layers of automated coverage:
+
+- **`tests/tester_v3_c.c`** — internal unit checks plus security regression tests (path traversal, negative `byteStride`, OOB indices, error-message lifetime, …). Build via `make` in `tests/`; run `./tester_v3_c` for the internal suite or `./tester_v3_c <file.gltf|file.glb>` to parse a single asset.
+- **`tests/tester_v3_c_v1port.c`** — v3 C port of the legacy unit tests, keeping behavioral parity with the old C++ API.
+- **`tests/tester_v3_json_c.c`** and **`tests/tester_v3_freestanding.c`** — JSON backend and freestanding (no libc) checks.
+- **`test_runner.py`** — model verifier that runs `tests/tester_v3_c` against every model in `glTF-Sample-Models/2.0` and validates the structured COUNTS/DIGEST output.
+- **`tests/v3/fuzzer/`** — libFuzzer harness with ASan + UBSan (`make run` builds and runs `fuzz_gltf_v3_c`). Crafted regression inputs live in `tests/v3/security/` and are seeded into `tests/v3/fuzzer/corpus/`.
+
+### Building
+
+```bash
+# Plain make (gcc/clang)
+$ make -C tests && make -C tests run
+
+# CMake
+$ cmake -B build && cmake --build build && ctest --test-dir build --output-on-failure
+
+# Meson
+$ meson setup build && meson compile -C build && meson test -C build
+
+# WebAssembly (requires an Emscripten SDK, defaults to ~/work/emsdk)
+$ make -C web && make -C web sample
+```
+
+## Web/WASM demo
+
+[`web/`](web/) contains a browser demo that compiles the v3 C runtime with
+Emscripten and renders glTF/GLB files with three.js (file picker + drag &
+drop). See [`web/README.md`](web/README.md) for build instructions.
+
+## Legacy v1/v2 (C++)
+
+The previous C++ implementation (`tiny_gltf.h`, `tiny_gltf.cc`,
+`tinygltf_json.h`, `json.hpp`, `loader_example.cc`, the C++ examples and
+tests) is deprecated and has been moved to [`attic/`](attic/) for reference.
+It is no longer built, tested, or installed. TinyGLTF v3 C is the mainline.

 ## Status

-Currently TinyGLTF is stable and maintenance mode. No drastic changes and feature additions planned.
-
- - v2.8.0 Add URICallbacks for custom URI handling in Buffer and Image. PR#397
- - v2.7.0 Change WriteImageDataFunction user callback function signature. PR#393
- - v2.6.0 Support serializing sparse accessor(Thanks to @fynv).
- - v2.5.0 Add SetPreserveImageChannels() option to load image data as is.
- - v2.4.0 Experimental RapidJSON support. Experimental C++14 support(C++14 may give better performance)
- - v2.3.0 Modified Material representation according to glTF 2.0 schema(and introduced TextureInfo class)
- - v2.2.0 release(Support loading 16bit PNG. Sparse accessor support)
- - v2.1.0 release(Draco decoding support)
- - v2.0.0 release(22 Aug, 2018)!
-
-### Branches
-
-* `sajson` : Use sajson to parse JSON. Parsing only but faster compile time(2x reduction compared to json.hpp and RapidJson), but not well maintained.
+TinyGLTF v3 (`tiny_gltf_v3.h` + `tiny_gltf_v3.c`) is the mainline release.
+API additions and behavior changes go through the usual review process.

-## Note on extension property
-
-In extension(`ExtensionMap`), JSON number value is parsed as int or float(number) and stored as `tinygltf::Value` object. If you want a floating point value from `tinygltf::Value`, use `GetNumberAsDouble()` method.
-
-`IsNumber()` returns true if the underlying value is an int value or a floating point value.
-
-## Examples
-
-* [glview](examples/glview) : Simple glTF geometry viewer.
-* [validator](examples/validator) : Simple glTF validator with JSON schema.
-* [basic](examples/basic) : Basic glTF viewer with texturing support.
-* [build-gltf](examples/build-gltf) : Build simple glTF scene from a scratch.
-
-### WASI/WASM build
-
-Users who want to run TinyGLTF securely and safely(e.g. need to handle malcious glTF file to serve online glTF conver),
-I recommend to build TinyGLTF for WASM target.
-WASI build example is located in [wasm](wasm) .

-
-
-## Build and example
-
-Copy `stb_image.h`, `stb_image_write.h`, `json.hpp` and `tiny_gltf.h` to your project.
-
-### Loading glTF 2.0 model
-
-```c++
-// Define these only in *one* .cc file.
-#define TINYGLTF_IMPLEMENTATION
-#define STB_IMAGE_IMPLEMENTATION
-#define STB_IMAGE_WRITE_IMPLEMENTATION
-// #define TINYGLTF_NOEXCEPTION // optional. disable exception handling.
-#include "tiny_gltf.h"
-
-using namespace tinygltf;
-
-Model model;
-TinyGLTF loader;
-std::string err;
-std::string warn;
-
-bool ret = loader.LoadASCIIFromFile(&model, &err, &warn, argv[1]);
-//bool ret = loader.LoadBinaryFromFile(&model, &err, &warn, argv[1]); // for binary glTF(.glb)
-
-if (!warn.empty()) {
-  printf("Warn: %s\n", warn.c_str());
-}
-
-if (!err.empty()) {
-  printf("Err: %s\n", err.c_str());
-}
-
-if (!ret) {
-  printf("Failed to parse glTF\n");
-  return -1;
-}
-```
-
-#### Loader options
-
-* `TinyGLTF::SetPreserveimageChannels(bool onoff)`. `true` to preserve image channels as stored in image file for loaded image. `false` by default for backward compatibility(image channels are widen to `RGBA` 4 channels). Effective only when using builtin image loader(STB image loader).
-
-## Compile options
-
-* `TINYGLTF_NOEXCEPTION` : Disable C++ exception in JSON parsing. You can use `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION` and `TINYGLTF_NOEXCEPTION`  to fully remove C++ exception codes when compiling TinyGLTF.
-* `TINYGLTF_NO_STB_IMAGE` : Do not load images with stb_image. Instead use `TinyGLTF::SetImageLoader(LoadimageDataFunction LoadImageData, void *user_data)` to set a callback for loading images.
-* `TINYGLTF_NO_STB_IMAGE_WRITE` : Do not write images with stb_image_write. Instead use `TinyGLTF::SetImageWriter(WriteimageDataFunction WriteImageData, void *user_data)` to set a callback for writing images.
-* `TINYGLTF_NO_EXTERNAL_IMAGE` : Do not try to load external image file. This option would be helpful if you do not want to load image files during glTF parsing.
-* `TINYGLTF_ANDROID_LOAD_FROM_ASSETS`: Load all files from packaged app assets instead of the regular file system. **Note:** You must pass a valid asset manager from your android app to `tinygltf::asset_manager` beforehand.
-* `TINYGLTF_ENABLE_DRACO`: Enable Draco compression. User must provide include path and link correspnding libraries in your project file.
-* `TINYGLTF_NO_INCLUDE_JSON `: Disable including `json.hpp` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_NO_INCLUDE_RAPIDJSON `: Disable including RapidJson's header files from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_NO_INCLUDE_STB_IMAGE `: Disable including `stb_image.h` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_NO_INCLUDE_STB_IMAGE_WRITE `: Disable including `stb_image_write.h` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.
-* `TINYGLTF_USE_RAPIDJSON` : Use RapidJSON as a JSON parser/serializer. RapidJSON files are not included in TinyGLTF repo. Please set an include path to RapidJSON if you enable this feature.
-* `TINYGLTF_USE_CPP14` : Use C++14 feature(requires C++14 compiler). This may give better performance than C++11.
-
-
-## CMake options
-
-You can add tinygltf using `add_subdirectory` feature.
-If you add tinygltf to your project using `add_subdirectory`, it would be better to set `TINYGLTF_HEADER_ONLY` on(just add an include path to tinygltf) and `TINYGLTF_INSTALL` off(Which does not install tinygltf files).
-
-```
-// Your project's CMakeLists.txt
-...
-
-set(TINYGLTF_HEADER_ONLY ON CACHE INTERNAL "" FORCE)
-set(TINYGLTF_INSTALL OFF CACHE INTERNAL "" FORCE)
-add_subdirectory(/path/to/tinygltf)
-```
-
-
-### Saving gltTF 2.0 model
-
-* Buffers.
-  * [x] To file
-  * [x] Embedded
-  * [ ] Draco compressed?
-* [x] Images
-  * [x] To file
-  * [x] Embedded
-* Binary(.glb)
-  * [x] .bin embedded single .glb
-  * [ ] External .bin
-
-## Running tests.
-
-### glTF parsing test
-
-#### Setup
-
-Python required.
-Git clone https://github.com/KhronosGroup/glTF-Sample-Models to your local dir.
-
-#### Run parsing test
-
-After building `loader_example`, edit `test_runner.py`, then,
-
-```bash
-$ python test_runner.py
-```
-
-### Unit tests
-
-```bash
-$ cd tests
-$ make
-$ ./tester
-$ ./tester_noexcept
-```
-
-### Fuzzing tests
-
-See `tests/fuzzer` for details.
-
-After running fuzzer on Ryzen9 3950X a week, at least `LoadASCIIFromString` looks safe except for out-of-memory error in Fuzzer.
-We may be better to introduce bounded memory size checking when parsing glTF data.
