+Thank you for your interest in fastfetch. This document covers building, architecture, how to add a module or a logo, code style, commit conventions, and the pull request workflow.
+
+fastfetch is a system information tool written in C23, supporting Linux, macOS, Windows, the BSDs, Solaris, Haiku and Android. The project places strong emphasis on **startup time** and on keeping **dependencies optional**; many design decisions only make sense under that constraint, and this document returns to it repeatedly.

+## Contributor quick reference
+
+| Task | Start here | Verify with |
+|---|---|---|
+| Build and run fastfetch | `run.sh`, `CMakeLists.txt` | `./run.sh` |
+| Add a module | `src/modules/<name>/`, `src/detection/<name>/`, `src/modules/modules.c`, `CMakeLists.txt` | `cmake -B build && cmake --build build -j` |
+| Add a platform implementation | `src/detection/<name>/<name>_<platform>.c`, the matching platform block in `CMakeLists.txt` | Build on the target platform or CI |
+| Add an ASCII logo | `src/logo/ascii/<letter>/<name>.txt`, matching `<letter>.inc` | `./build/fastfetch --logo <name>` |
+| Change formatting or JSON output | `src/modules/<name>/<name>.c` | `./build/fastfetch -s <name> --format json` |
+| Change shared formatting or containers | `src/common/format.h`, `src/common/color.h`, `src/common/FFstrbuf.h` | Build and run the matching test |
+| Run the test suite | `tests/`, `build/` | `cd build && ctest --output-on-failure` |
+
+For a typical code change, the shortest useful iteration is: configure, build the `fastfetch` target, run the affected module, then run the tests. If you add a directory or a generated input, re-run `cmake -B build` so that CMake refreshes its file globs.
+
+---
+
+## Getting started
+
+### Building
+
+The quickest way is `run.sh` in the repository root: it creates `build/`, configures, compiles and runs the binary.
+
+```sh
+./run.sh                 # build and run
+./run.sh --format json   # arguments are forwarded to fastfetch
+```
+
+Manual build:
+
+```sh
+cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
+cmake --build build --target fastfetch -j$(nproc)
+./build/fastfetch
+```
+
+The default build type is `RelWithDebInfo`. LTO is enabled whenever `ENABLE_LTO=ON` **and** `CMAKE_BUILD_TYPE != Debug`, so the default configuration enables it and only `Debug` builds omit it. This is significant because LTO here is not merely an optimization: it is what removes the code of disabled modules. See [Pitfalls](#pitfalls).
+
+### Common build options
+
+| Option | Default | Notes |
+|---|---|---|
+| `CMAKE_BUILD_TYPE` | `RelWithDebInfo` | LTO is on for anything but `Debug` |
+| `BUILD_TESTS` | `OFF` | Builds the unit tests in `tests/` |
+| `BUILD_FLASHFETCH` | `ON` | Also builds the stripped-down `flashfetch` |
+| `BINARY_LINK_TYPE` | `dlopen` | `dlopen` / `dynamic` / `static` |
+| `ENABLE_ASAN` | `OFF` | Address Sanitizer |
+| `ENABLE_LTO` | `ON` | Link-time optimization |
+| `MODULE_DISABLE_<NAME>` | `OFF` | Disable a module, e.g. `MODULE_DISABLE_GPU=ON` |
+| `SET_TWEAK` | `ON` | Appends a tweak to the dev version; turned off for releases |
+
+`BINARY_LINK_TYPE=dlopen` (the default) is a deliberate design choice: optional dependencies (Vulkan, Wayland, DBus, ImageMagick, chafa, …) are loaded at runtime, so a missing library never prevents startup. When adding a third-party dependency, use the dlopen helpers in `common/library.h` — do not link it directly.
+
+For a minimal-dependency build, see `.github/workflows/build-no-features-test.yml`:
+
+```sh
+cmake -DBUILD_TESTS=On -DENABLE_VULKAN=OFF -DENABLE_WAYLAND=OFF -DENABLE_X11=OFF \
+      -DENABLE_DBUS=OFF -DENABLE_ZLIB=OFF ... .
+```
+
+### Dependencies
+
+Required: CMake ≥ 3.21 and a C23 compiler (GCC, Clang or MSVC). Everything else is optional.
+
+Optional dependencies are auto-detected: libpci, libdrm, vulkan, wayland, xcb, xrandr, dbus, sqlite3, rpm, imagemagick{6,7}, chafa, zlib, egl, glx, opencl, freetype, elf, libzfs, and more.
+

+
+## Code map
+
+```
+src/
+├── fastfetch.c          entry point: CLI parsing, module dispatch, main loop (36 KB)
+├── flashfetch.c         entry point for the stripped-down build
+├── options/             global (non-module) config: general / display / logo
+├── modules/             module layer — module formatting and output
+├── detection/           detection layer — platform-specific data retrieval
+├── common/              infrastructure: FFstrbuf, FFlist, formatting, printing, networking
+├── logo/                530 ASCII logos plus the image logo backends
+└── 3rdparty/            yyjson, widecharwidth, display-library
+```
+
+Flow of control:
+
+```
+fastfetch.c  →  options/    (global configuration)
+             →  modules/    (76 modules, formatting and output)
+             →  detection/  (one platform implementation each, raw data)
+             →  common/     (infrastructure)
+```
+
+The number of module directories does not match the number of detection directories, which is expected. The following relationships are structural rather than a fixed inventory:
+
+- **13 modules have no detection directory** — they are either pure layout (`break`, `separator`, `colors`, `title`, `logo`) or reuse another module's detection result (`display`, `monitor`, `kernel`, `shell`, `terminal`, `player`, `custom`, `datetime`).
+- **4 detection directories serve modules with different names** — `displayserver` (→ `display`, `monitor`), `gtk_qt` (→ `theme`, `icons`, `font`, `cursor`), `terminalshell` (→ `terminal`, `shell`) and `libc`.
+
+Therefore, do not assume that `modules/<x>/` always has a matching `detection/<x>/`.
+
+### Layer boundaries
+
+| Layer | Owns | Must not |
+|---|---|---|
+| `options/` | **Global** config (colors, logo, threading, timeouts) | hold per-module options |
+| `modules/` | formatting, printing, JSON serialization | read `/proc`, call Win32 APIs, parse sysfs |
+| `detection/` | cross-platform data retrieval, clean result structs | print anything, read display config |
+| `common/` | general-purpose utilities, no business logic | depend on a specific module |
+
+A simple check: **no file under `detection/` should contain `printf` or read `instance.config`.** Symmetrically, no file under `modules/` should contain `#ifdef __linux__`.
+
+---
+
+## Core architecture: modules vs. detection
+
+This is the most important convention in the codebase. Every feature consists of a fixed set of files; using CPU as the example:
+
+```
+modules/cpu/option.h           module option struct
+modules/cpu/cpu.c              formatting and output
+detection/cpu/cpu.h            platform-independent interface
+detection/cpu/cpu_linux.c     ┐
+detection/cpu/cpu_apple.c     │
+detection/cpu/cpu_windows.c   ├─ platform implementations, one linked per build
+detection/cpu/cpu_bsd.c       │
+detection/cpu/cpu_nosupport.c ┘
+```
+
+The interface is deliberately minimal, typically consisting of only two declarations:
+
+```c
+typedef struct FFCPUResult { ... } FFCPUResult;   // result struct
+const char* ffDetectCPU(const FFCPUOptions* options, FFCPUResult* cpu);
+```
+
+The `const char*` return value is an **error string**; `nullptr` means success. This pattern is used throughout `detection/` — please keep it consistent.
+
+Helper functions are only exposed when they are genuinely shared between platform implementations (as in `cpu.h`: `ffCPUAppleCodeToName`, `ffCPUDetectByCpuid`).
+
+**The benefit of this separation:** adding a platform never touches `modules/`; fixing output formatting never touches `detection/`.
+
+---
+
+## Module registration
+
+### The descriptor
+
+Every module exports one `FFModuleBaseInfo` (defined in `common/option.h:46`) — essentially a hand-written vtable:
+
+```c
+typedef struct FFModuleBaseInfo {
+    const char* name;                    // lookup key, e.g. "cpu"
+    const char* description;             // help text
+    FFModuleDisplayName displayName;     // module name in 20 languages
+
+    void (*initOptions)(void* options);
+    void (*destroyOptions)(void* options);
+    void (*parseJsonObject)(void* options, struct yyjson_val* module);
+    bool (*printModule)(void* options);
+    bool (*generateJsonResult)(void* options, yyjson_mut_doc*, yyjson_mut_val*);
+    void (*generateJsonConfig)(void* options, yyjson_mut_doc*, yyjson_mut_val*);
+
+    FFModuleFormatArgList formatArgs;    // format placeholder table
+    const uint8_t defaultOrder;          // sort weight
+} FFModuleBaseInfo;
+```
+
+The source comment acknowledges that this is undefined behavior, since `void*` is not compatible with `FF*Options*`. It is a pragmatic compromise to obtain polymorphism in C; do not attempt to "fix" it.
+
+### The registry: a first-letter hash bucket
+
+`src/modules/modules.c` defines 26 `static FFModuleBaseInfo*` arrays (`A[]` through `Z[]`), each terminated by `nullptr`, collected into `ffModuleInfos[26]`:
+
+```c
+FFModuleBaseInfo** modules = ffModuleInfos[toupper(name[0]) - 'A'];  // O(1) bucket lookup
+for (; *modules; ++modules) {                                        // linear scan in the bucket
+    if (ffStrEqualsIgnCase(name, (*modules)->name)) { ... }
+}
+```
+
+Because the registry is small, a single arithmetic bucket lookup followed by a few string comparisons is preferable to a general-purpose hash table. When adding a module, place its descriptor in the bucket matching the first letter of `.name`, and keep the existing `nullptr` terminator at the end.
+
+### The calling convention: zero heap allocation
+
+Every dispatch site (`jsonconfig.c:98`, `commandoption.c:189`) follows the same pattern:
+
+```c
+alignas(uint64_t) uint8_t optionBuf[FF_OPTION_MAX_SIZE];  // 256 bytes, on the stack
+baseInfo->initOptions(optionBuf);
+baseInfo->parseJsonObject(optionBuf, jsonVal);             // JSONC path only
+baseInfo->printModule(optionBuf);                          // or generateJsonResult
+baseInfo->destroyOptions(optionBuf);
+```
+
+`FF_OPTION_MAX_SIZE = 1 << 8` (256 bytes). Every module's `option.h` must end with:
+
+```c
+static_assert(sizeof(FFCPUOptions) <= FF_OPTION_MAX_SIZE, "FFCPUOptions size exceeds maximum allowed size");
+```
+
+**In other words, no module option struct may exceed 256 bytes.** This is a hard constraint, enforced at compile time.
+
+The three dispatch entry points:
+
+| Entry point | Location | Used for |
+|---|---|---|
+| `parseModuleJsonObject` | `common/impl/jsonconfig.c:90` | the `modules[]` array in a JSONC config |
+| `parseStructureCommand` | `common/impl/commandoption.c:181` | the colon-separated structure string |
+
+### Build-time module discovery
+
+`CMakeLists.txt:134` globs `src/modules/*/*.c`, keeps only the entries whose file name matches their directory name, and generates a `MODULE_DISABLE_<UPPER>` option for each:
+
+```cmake
+file(GLOB FF_MODULE_SRCS CONFIGURE_DEPENDS RELATIVE "..." ".../src/modules/*/*.c")
+set(FF_MODULE_DIRS "")
+foreach(FF_MODULE_SRC ${FF_MODULE_SRCS})
+    get_filename_component(FF_MODULE_DIR "${FF_MODULE_SRC}" DIRECTORY)
+    get_filename_component(FF_MODULE_NAME "${FF_MODULE_SRC}" NAME_WE)
+    if("${FF_MODULE_DIR}" STREQUAL "${FF_MODULE_NAME}")
+        list(APPEND FF_MODULE_DIRS "${FF_MODULE_DIR}")
+    endif()
+endforeach()
+
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    string(TOUPPER "${FF_MODULE_DIR}" FF_MODULE_UPPER)
+    option(MODULE_DISABLE_${FF_MODULE_UPPER} "Disable module ${FF_MODULE_DIR}" OFF)
+endforeach()
+```
+
+Because the glob matches sources rather than directories, a directory counts as a module only when `src/modules/<name>/<name>.c` exists. Empty directories — which git does not track, so they are easy to leave behind — and stray files are ignored instead of breaking the configure step with `Cannot find source file`.
+
+### Module sources are discovered automatically
+
+`FF_MODULE_DIRS` also drives the source list (`CMakeLists.txt:516`):
+
+```cmake
+foreach(FF_MODULE_DIR ${FF_MODULE_DIRS})
+    list(APPEND LIBFASTFETCH_SRC
+        src/modules/${FF_MODULE_DIR}/${FF_MODULE_DIR}.c
+    )
+endforeach()
+```
+
+Consequences:
+
+- `src/modules/<name>/<name>.c` is compiled as soon as the file exists — **there is no source list to edit for the module layer**.
+- The file name must match the directory name. A directory whose `.c` file is named differently, or has none at all, is silently not a module: a typo therefore shows up as a module missing from `fastfetch --list-modules`, not as a build error.
+- The glob uses `CONFIGURE_DEPENDS`, so with the Makefile and Ninja generators the build re-evaluates it and re-runs CMake when a module source is added or removed. With other generators, or to be safe, re-run `cmake -B build` explicitly.
+
+Only the module layer is automated. Sources under `src/detection/` and `src/common/impl/` are **not** globbed and must still be listed by hand — see [step 5](#5-add-the-platform-sources-to-cmakeliststxt).
+
+---
+
+## Walkthrough: adding a module
+
+Adding a `Foo` module, step by step.
+
+### 1. Define the option struct
+
+`src/modules/foo/option.h`:
+
+```c
+#pragma once
+
+#include "common/option.h"
+
+typedef struct FFFooOptions {
+    FFModuleArgs moduleArgs;   // must be the first field
+    bool showBar;
+} FFFooOptions;
+
+static_assert(sizeof(FFFooOptions) <= FF_OPTION_MAX_SIZE, "FFFooOptions size exceeds maximum allowed size");
+```
+
+`FFModuleArgs` must come first. It provides `key`, `format`, `outputColor`, `keyColor`, `keyIcon` and `keyWidth`; because it is the first field, `ffJsonConfigParseModuleArgs()` handles these generically, **so no parsing code is required**.
+
+### 2. Implement detection
+
+`src/detection/foo/foo.h`:
+
+```c
+#pragma once
+#include "fastfetch.h"
+
+typedef struct FFFooResult {
+    FFstrbuf name;
+    uint32_t count;
+} FFFooResult;
+
+const char* ffDetectFoo(const FFFooOptions* options, FFFooResult* result);
+```
+
+`src/detection/foo/foo_linux.c`:
+
+```c
+#include "foo.h"
+
+const char* ffDetectFoo(const FFFooOptions* options, FFFooResult* result) {
+    // read /sys, /proc, sysfs, dbus, ...
+    return nullptr;  // success; return an error string on failure
+}
+```
+
+**Write one file per target platform, plus a `foo_nosupport.c` fallback for the remaining platforms.** The repository currently contains 45 `*_nosupport.c` files serving this purpose.
+
+### 3. Implement the module
+
+`src/modules/foo/foo.c` — implement the six functions, then define the descriptor:
+
+```c
+FFModuleBaseInfo ffFooModuleInfo = {
+    .name = "Foo",
+    .description = "Print foo information",
+    .displayName = {
+        .en = "Foo", .ar = "Foo", .cs = "Foo", .de = "Foo", .es = "Foo",
+        .fr = "Foo", .gl = "Foo", .he = "Foo", .id = "Foo", .it = "Foo",
+        .ja = "Foo", .ko = "Foo", .pl = "Foo", .pt = "Foo", .ru = "Foo",
+        .tr = "Foo", .uk = "Foo", .vi = "Foo", .zh_CN = "Foo", .zh_TW = "Foo",
+    },
+    .initOptions = (void*) ffInitFooOptions,
+    .destroyOptions = (void*) ffDestroyFooOptions,
+    .parseJsonObject = (void*) ffParseFooJsonObject,
+    .printModule = (void*) ffPrintFoo,
+    .generateJsonResult = (void*) ffGenerateFooJsonResult,
+    .generateJsonConfig = (void*) ffGenerateFooJsonConfig,
+    .formatArgs = FF_FORMAT_ARG_LIST(((FFModuleFormatArg[]) {
+        { "Name", "name" },
+        { "Count", "count" },
+    })),
+    .defaultOrder = 73,
+};
+```
+
+Points to note:
+
+- **`displayName`** is a literal block of all 20 language fields; there is no shortcut macro, so copy the layout from an existing module: **`en`, `ar`, `cs`, `de`, `es`, `fr`, `gl`, `he`, `id`, `it`, `ja`, `ko`, `pl`, `pt`, `ru`, `tr`, `uk`, `vi`, `zh_CN`, `zh_TW`**.
+  **Fill in all 20.** The struct is read by byte offset (see [Pitfalls](#6-localization-uses-byte-offsets-not-enums)) and there is **no fallback** — a missing field means the key prints empty in that language.
+- **`formatArgs`** must be exhaustive. It drives the placeholder list printed by `fastfetch -h foo-format`; **any placeholder omitted here is neither listed nor usable by the user.**
+- The `moduleFormat` section in `doc/json_schema.json` is generated by `fastfetch -h format-json`. Its metadata comes from `FFModuleBaseInfo::formatArgs`. To keep the schema and module descriptors consistent, do not edit the `moduleFormat` section in `doc/json_schema.json` by hand; update the module metadata and regenerate it instead.
+- **`defaultOrder`**: use the current maximum plus 1. Search the existing descriptors for `.defaultOrder =` before choosing a value; do not copy a hard-coded value from this document. Leaving it out, or setting it to `0`, excludes the module from the interactive `--gen-config` picker. Only `logo`, `command` and `custom` rely on this behavior, because they require user arguments or are invoked directly by the display layer.
+
+### 4. Register it
+
+- Add `#include "modules/foo/foo.h"` to `src/modules/modules.h`
+- Insert into the `F[]` array in `src/modules/modules.c`:
+
+```c
+#if !FF_MODULE_DISABLE_FOO
+    &ffFooModuleInfo,
+#endif
+```
+
+`FF_MODULE_DISABLE_FOO` is generated by CMake — you do not define it yourself.
+
+### 5. Add the platform sources to `CMakeLists.txt`
+
+The module layer is discovered by glob (see [Build-time module discovery](#module-sources-are-discovered-automatically)), **but `src/detection/**` and `src/common/impl/**` are not**. `CMakeLists.txt` lists them explicitly, inside one mutually exclusive chain of platform blocks:
+
+| Block | Line | Covers |
+|---|---|---|
+| `if(LINUX)` | `CMakeLists.txt:522` | Linux |
+| `elseif(ANDROID)` | `CMakeLists.txt:608` | Android (Termux) |
+| `elseif(FreeBSD)` | `CMakeLists.txt:691` | FreeBSD, MidnightBSD, DragonFly |
+| `elseif(NetBSD)` | `CMakeLists.txt:788` | NetBSD |
+| `elseif(OpenBSD)` | `CMakeLists.txt:872` | OpenBSD |
+| `elseif(APPLE)` | `CMakeLists.txt:959` | macOS / iOS |
+| `elseif(WIN32)` | `CMakeLists.txt:1046` | Windows |
+| `elseif(SunOS)` | `CMakeLists.txt:1121` | Solaris / illumos |
+| `elseif(Haiku)` | `CMakeLists.txt:1204` | Haiku |
+| `elseif(GNU)` | `CMakeLists.txt:1282` | GNU/Hurd |
+
+Add the platform implementation to every block whose platform it supports, and `foo_nosupport.c` to every remaining block, so that all ten platforms still link:
+
+```cmake
+elseif(FreeBSD)
+    list(APPEND LIBFASTFETCH_SRC
+        ...
+        src/detection/foo/foo_bsd.c
+    )
+```
+
+Points to note:
+
+- Exactly one block is compiled per build, so a file omitted from a block does not exist for that platform, and the link fails with an undefined reference to `ffDetectFoo()` — **on that platform only**. A missing entry therefore builds fine locally and fails in CI; this is why every block must be covered.
+- A platform may reuse another platform's implementation instead of a stub. `src/common/impl/networking_linux.c`, for example, is listed in nine of the ten blocks (all but `WIN32`). Check where the closest sibling module points before adding a new file.
+- `DragonFly` is handled by the inner `if(DragonFly)` sub-block inside the FreeBSD block (`CMakeLists.txt:773`); add the variant there, as `processes`, `top` and `wifi` do.
+- New helpers under `src/common/impl/` follow the same rule: they are not globbed, and each block that needs one must list it.
+- A few files are appended outside the platform chain because they depend on an option or on a specific feature — for example the proprietary GPU backends (`CMakeLists.txt:1379`) and `src/common/impl/wcwidth.c` (`CMakeLists.txt:1408`). Those are written by hand as well.
+
+### 6. Modules that need warm-up
+
+If your module needs a sampling interval (CPU usage) or a network round-trip (public IP, weather), also implement `ffPrepareFoo()` and register it in the switch inside `ffPrepareCommandOption()` in `common/impl/commandoption.c`, under the matching first-letter `case`. Six modules currently do this: CPUUsage, DiskIO, NetIO, PublicIP, Top and Weather.
+
+### 7. Verify
+
+```sh
+cmake -B build && cmake --build build -j
+./build/fastfetch -s foo --format json    # JSON output
+./build/fastfetch -h foo-format           # list formatArgs placeholders
+./build/fastfetch --gen-config            # confirm it appears in the picker
+```
+
+Note the `-format` suffix on the help flag: `fastfetch -h foo` is not supported; only `fastfetch -h foo-format` works.
+
+If you added detection sources, re-check [step 5](#5-add-the-platform-sources-to-cmakeliststxt) before pushing: a platform block you missed compiles fine locally and fails only when that platform is built.

+
+## Walkthrough: adding a logo
+
+A new logo **must** have a corresponding "Logo Request" issue, linked from the PR with `Closes #1234`. Logo PRs without a linked issue are not accepted.
+
+### 1. Add the ASCII file
+
+```
+src/logo/ascii/<first-letter>/<distro>.txt
+```
+
+For example `src/logo/ascii/d/distro.txt`. Directories are already split by first letter (`a/` … `z/`, plus `_/`).
+
+The file is plain ASCII art with `$1` … `$9` as color placeholders:
+
+```
+                 $3 ,-^-___
+$3                /\\\///
+$2refined.$1       /\\\\//
+```
+
+- `$1` … `$9` map to palette slots 1–9; at most 9 are supported (`FASTFETCH_LOGO_MAX_COLORS = 9`)
+- `$$` is a literal `$`
+- Characters without a placeholder inherit the current color. Of the 530 existing logos, 239 use no placeholders at all (monochrome) and 291 do; **new logos should use placeholders**, as monochrome is a legacy style
+- Tabs are expanded to 4 spaces
+- Colors can be overridden with `--logo-color-1` … `--logo-color-9`
+
+### 2. Register it in the `.inc`
+
+CMake turns each `.txt` file into a `FASTFETCH_DATATEXT_LOGO_<UPPERCASE>` macro (`CMakeLists.txt:418`), but **the registry itself is maintained by hand**. Edit `src/logo/ascii/<first-letter>.inc`:
+
+```c
+// src/logo/ascii/d.inc
+
+#ifdef FASTFETCH_DATATEXT_LOGO_DISTRO
+// Distro
+{
+    .names = { "Distro" }, // ID (preferred) or NAME from /etc/os-release, do NOT add both
+    .lines = FASTFETCH_DATATEXT_LOGO_DISTRO,
+    .colors = {
+        FF_COLOR_FG_PRIMARY, // recommended for using as WHITE replacement, light-theme terminal friendly
+        FF_COLOR_FG_BLUE, // preferred
+        FF_COLOR_FG_256 "34",
+        FF_COLOR_FG_RGB "0;255;0", // not recommended because of bad compatibility with raw TTY
+    },
+},
+#endif
+```
+
+- `names` is matched case-insensitively. Do not add names that differ only by case, because they can never be distinguished. Every name is also shown by `--list-logos`, so use user-friendly spelling such as an initial capital where appropriate.
+- For a new logo, use exactly one name unless there is a specific compatibility reason to add more. That name should first be the `ID` from `/etc/os-release`. If the ID cannot distinguish this logo from another logo for the same OS, use the `NAME` value instead. `logoGetBuiltinDetected` in `src/logo/logo.c` documents the detection order: `ID`, then `NAME`, then tokens from `ID_LIKE`, then the platform name fallback. Manual `logo-source` selection uses the name directly.
+- `colors` is positional — entry 0 is `$1`, entry 1 is `$2`, and so on
+- `colors[0]` also becomes the title color and `colors[1]` the key color, unless the user overrides them
+
+If the same OS has multiple logo variants, mark the variant explicitly with `.type`:
+
+```c
+.type = FF_LOGO_LINE_TYPE_SMALL_BIT,
+```
+
+Use `FF_LOGO_LINE_TYPE_ALTER_BIT` for an alternate logo, `FF_LOGO_LINE_TYPE_SMALL_BIT` for a small logo, or combine the flags when both apply. This is also a lookup optimization: a logo marked `FF_LOGO_LINE_TYPE_SMALL_BIT` is considered only for `type = small`, while a logo marked `FF_LOGO_LINE_TYPE_ALTER_BIT` is never selected by automatic detection. Alternate logos are available only when explicitly requested through `-l <source>`.
+
+### 3. Verify
+
+```sh
+./build/fastfetch -l distro
+./build/fastfetch --list-logos | grep -i distro
+```
+
+---
+
+## Platform conventions
+
+The `detection/` layer picks its implementation by **filename suffix**; the choice is made at build time from `CMAKE_SYSTEM_NAME`:
+
+| Suffix | Platform |
+|---|---|
+| `_linux.c` | Linux |
+| `_apple.c` / `_apple.m` | macOS / iOS (`.m` for Objective-C) |
+| `_windows.c` / `_windows.cpp` | Windows (`.cpp` for WinRT / WMI) |
+| `_bsd.c` | FreeBSD |
+| `_nbsd.c` | NetBSD |
+| `_obsd.c` | OpenBSD |
+| `_sunos.c` | Solaris / illumos |
+| `_haiku.c` / `.cpp` | Haiku |
+| `_android.c` | Android (Termux) |
+| `_gnu.c` | GNU/Hurd |
+| `_nosupport.c` | Empty fallback |
+
+Current distribution of platform files in `detection/`:
+
+| Suffix | Files | Suffix | Files |
+|---|---|---|---|
+| `_linux` | 58 | `_obsd` | 16 |
+| `_windows` | 47 | `_haiku` | 13 |
+| `_apple` | 46 | `_android` | 12 |
+| `_nosupport` | 45 | `_gnu` | 3 |
+| `_bsd` | 29 | | |
+| `_sunos` | 19 | | |
+| `_nbsd` | 17 | | |
+
+(These are repository inventory figures, counting `.c`, `.m`, `.cpp`, and `.h`; they may change as platforms and modules are added.)
+
+**Do not accumulate `#ifdef __linux__` blocks in a single file.** When adding platform support, copy the closest existing implementation and change the suffix.
+
+`common/` follows the same convention: `common/impl/` contains `io_unix.c` / `io_windows.c`, `netif_linux.c` / `netif_apple.c` / `netif_bsd.c` and similar files, with `common/apple/`, `common/windows/` and `common/haiku/` holding platform-specific helpers.
+
+When several platform suffixes could apply, use the most specific implementation supported by the build system (for example, `_nbsd.c` instead of the generic `_bsd.c` on NetBSD). Keep the generic file as the fallback for platforms that share its conventions.
+
+---
+
+## Code style
+
+### Formatting
+
+The project uses clang-format with `BasedOnStyle: LLVM` plus these key overrides:
+
+```yaml
+IndentWidth: 4
+UseTab: Never
+ColumnLimit: 0              # never wrap
+InsertBraces: true          # braces even on single-statement ifs
+PointerAlignment: Left      # char* p, not char *p
+SortIncludes: Never         # include order is managed by hand
+AlignAfterOpenBracket: DontAlign
+BinPackParameters: false    # all params on one line, or one per line
+```
+
+Before committing:
+
+```sh
+clang-format -i src/modules/foo/*.c src/modules/foo/*.h
+```
+
+`src/3rdparty/**`, `build/**` and `src/logo/builtin.c` are listed in `.clang-format-ignore` — **do not reformat them.**
+
+`.editorconfig` specifies LF line endings, a 4-space indent, a final newline, and trailing whitespace trimmed (except in Markdown).
+
+### Naming
+
+| Kind | Convention | Example |
+|---|---|---|
+| Functions | `ff` + PascalCase | `ffDetectCPU`, `ffPrintCPU` |
+| Types | `FF` + PascalCase | `FFCPUResult`, `FFModuleBaseInfo` |
+| Variables / fields | camelCase | `coresPhysical`, `keyWidth` |
+| Macros | SCREAMING_SNAKE_CASE | `FF_OPTION_MAX_SIZE` |
+| Module options | `FF<Name>Options` | `FFCPUOptions` |
+| Detection results | `FF<Name>Result` | `FFCPUResult` |
+
+### Compiler warnings
+
+The build enables `-Wall -Wextra -Wconversion` plus several `-Werror`s:
+
+```
+-Werror=uninitialized -Werror=return-type -Werror=vla
+-Werror=incompatible-pointer-types -Werror=implicit-function-declaration -Werror=int-conversion
+```
+
+**`-Wconversion` is strict**: every implicit narrowing conversion needs an explicit cast.
+

+
+Scope is the module or subsystem name; Platform is optional. Use the third-person singular present tense, capitalize the first letter, no trailing period.
+
+Real examples from recent history:
+
+```
+Processes (Haiku): honors `options->countKprocs`
+WM (macOS): improves reliability of WM plugin detection
+Memory (Windows): prefers `NQSI`
+Top (Linux): improves performance of `stat` parsing
+Logo (Builtin): adds omarchy
+Global: introduces global macro `FF_PATH_PKG_BASE` to replace `_PATH_LOCALBASE`
+LM (OpenBSD): adds support
+CI: disables fail on alert
+Doc: updates README

+
+Common verbs: `adds`, `removes`, `fixes`, `improves`, `updates`, `corrects`, `prefers`, `honors`, `disables`, `enables`, `introduces`, `detects`, `reports`, `skips`, `uses`.
+
+Scopes in use: `Top`, `Processes`, `Memory`, `Logo (Builtin)`, `CI`, `Doc`, `Presets`, `Global`, plus individual module names.
+
+Documentation-only changes use a `[ci skip]` suffix.

+## Tests
+
+Tests are standalone executables in `tests/` using a `VERIFY` macro that exits non-zero on failure:
+
+```c
+#define VERIFY(expression) \
+    if (!(expression)) testFailed(&strbuf, #expression, __LINE__)
+```
+
+Current tests: `strbuf.c`, `list.c`, `format.c`, `color.c`, `duration.c`, `strutil.c`.
+
+```sh
+cmake -B build -DBUILD_TESTS=On
+cmake --build build
+cd build && ctest --output-on-failure
+```
+
+Coverage focuses on the core data structures and the formatting engine in `common/`. The `detection/` layer has no automated tests, because it depends on the state of a running system; it is instead covered by the CI matrix — 20 workflows under `.github/workflows/` spanning Linux (including musl, loong64, armv7l, i686), macOS, Windows, FreeBSD, NetBSD, OpenBSD, DragonFly, Solaris, OmniOS and Haiku, plus spellcheck and benchmark jobs.
+
+**If you modify `common/FFstrbuf.h`, `common/format.h` or `common/color.h`, extend the corresponding test.**

+```
+
+---
+
+## Pitfalls
+
+The following points are easy to misinterpret when reading this codebase. Most of them follow from the startup-time objective described above.
+
+### 1. Option structs must not exceed 256 bytes
+
+`FF_OPTION_MAX_SIZE = 1 << 8`. Exceeding it is caught at compile time by `static_assert`. Do not attempt to increase the value: it determines the stack cost of every module invocation.
+
+### 2. `FF_MODULE_DISABLE_*` controls registration, not compilation
+
+```c
+// verbatim from the top of modules/modules.c:
+// FF_MODULE_DISABLE_<module> only controls if the module is registered,
+// the module code itself is still compiled.
+// We rely `LTO` to remove the unused code (only enabled in Release mode)
+```
+
+**Disabling modules in a Debug build does not shrink the binary.** LTO is enabled whenever `CMAKE_BUILD_TYPE != Debug`, and the default `RelWithDebInfo` already satisfies that — so measure size with `RelWithDebInfo` or `Release`, never with `Debug`. (The "Release mode" wording in the comment above is imprecise.)
+
+### 3. Only two things are discovered by glob
+
+The module sources (`CMakeLists.txt:134`) and the logo `.txt` files (`CMakeLists.txt:429`). Both use `CONFIGURE_DEPENDS`, so with the Makefile and Ninja generators the build re-checks the glob and re-runs CMake when the result changes; other generators (Visual Studio and Xcode in particular) do not track it as reliably. Re-run `cmake -B build` after adding a module source or a logo file rather than relying on that behavior.
+
+Everything else — `src/detection/**` and `src/common/impl/**`, and any source outside the platform chain — must be listed in `CMakeLists.txt` by hand; see [step 5](#5-add-the-platform-sources-to-cmakeliststxt).
+
+### 4. CLI module options are removed
+
+Per-module command-line flags such as `--cpu-temp` are **no longer supported**. The only job of `ffParseModuleOptions` now is to translate the flag into a JSON key, then `exit(477)` with a pointer to the config file:
+
+```
+Error: Unsupported module option: --cpu-temp
+       Support of module options has been removed. Please add the flag to the JSON config instead.
+       Example (demonstration only): `{ "modules": [ { "type": "cpu", "temp": true } ] }`
+```
+
+**JSONC is the first-class configuration interface; the command line is not.** When adding module options, implement `parseJsonObject` only — do not add a CLI branch.
+
+### 5. `defaultOrder = 0` hides a module from `--gen-config`
+
+`collectModuleInfos` (`genconfig.c:186`) skips any module whose `defaultOrder` is `0`. C zero-initializes the field, so **omitting it is the same as setting it to 0**. Only `logo`, `command` and `custom` rely on this intentionally.
+
+`defaultOrder` affects only the ordering in the interactive `--gen-config` picker; it has no effect on the runtime output order.
+
+### 6. Localization uses byte offsets, not enums
+
+`instance.config.display.keyLanguage` does not hold a language enum — it holds a **byte offset** such as `offsetof(FFModuleDisplayName, zh_CN)`. The macro `FF_MODULE_GET_DISPLAY_NAME` (`common/option.h:123`) does plain pointer arithmetic with it:
+
+```c
+#define FF_MODULE_GET_DISPLAY_NAME(moduleName) \
+    (*(const char**) ((uint8_t*) &ff ## moduleName ## ModuleInfo.displayName + instance.config.display.keyLanguage))
+```
+
+Consequence: **the field order of `FFModuleDisplayName` must never change** — reordering the fields silently corrupts the output for every language.
+
+### 7. The `multithreading` option has limited effect
+
+The global `multithreading` option currently takes effect in exactly one place: `common/impl/networking_linux.c:339`. Modules are still printed sequentially. Modules that need concurrency go through the `ffPrepare*` warm-up hooks instead, which start sampling or fire off requests before the print loop begins.
+
+This may change in the future. The main blocking issue is that there are dependencies between different modules.
+
+### 8. Do not print or read configuration inside `detection/`
+
+The `detection/` layer must stay pure: read system state, fill a struct, return an error string. Any `printf` or any read of `instance.config` there is a design error.
+
+Use `FF_DEBUG` (`src/common/debug.h`) for logging.
+
+### 9. `src/logo/builtin.c` and `3rdparty/` are formatting-exempt
+
+The former is a large generated and hand-maintained data table; the latter is upstream code. Both are excluded via `.clang-format-ignore`; do not reformat either.

+Key Format Structure Explanation:
+
+The key format uses a combination of:
+1. Unicode box drawing characters (│ ┌ ┐ └ ┘ ┬ ┴) for borders
+2. ANSI escape codes for cursor positioning (\u001b[...)
+3. Format variables ({icon}, {sysname}, etc.)
+4. Constant references ({$1}, {$2}, etc.)
+5. Color formatting ({#color})
+
+ANSI Escape Codes Used:
+- \u001b[s      - Save cursor position (ESC[s)
+- \u001b[u      - Restore cursor position (ESC[u)
+- \u001b[nC     - Move cursor right n columns (ESC[nC)
+- \u001b[nD     - Move cursor left n columns (ESC[nD)
+
+This creates a table-like layout with fixed column widths and proper alignment,
+regardless of the actual content length in each field.
+
+For more ANSI escape code reference, see:
+https://gist.github.com/fnky/458719343aabd01cfb17a3a4f7296797#cursor-controls

- * This is an implementation of wcwidth() and wcswidth() (defined in
- * IEEE Std 1002.1-2001) for Unicode.

- * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
- * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
- *
- * In fixed-width output devices, Latin characters all occupy a single
- * "cell" position of equal width, whereas ideographic CJK characters
- * occupy two such cells. Interoperability between terminal-line
- * applications and (teletype-style) character terminals using the
- * UTF-8 encoding requires agreement on which character should advance
- * the cursor by how many cell positions. No established formal
- * standards exist at present on which Unicode character shall occupy
- * how many cell positions on character terminals. These routines are
- * a first attempt of defining such behavior based on simple rules
- * applied to data provided by the Unicode Consortium.
- *
- * For some graphical characters, the Unicode standard explicitly
- * defines a character-cell width via the definition of the East Asian
- * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
- * In all these cases, there is no ambiguity about which width a
- * terminal shall use. For characters in the East Asian Ambiguous (A)
- * class, the width choice depends purely on a preference of backward
- * compatibility with either historic CJK or Western practice.
- * Choosing single-width for these characters is easy to justify as
- * the appropriate long-term solution, as the CJK practice of
- * displaying these characters as double-width comes from historic
- * implementation simplicity (8-bit encoded characters were displayed
- * single-width and 16-bit ones double-width, even for Greek,
- * Cyrillic, etc.) and not any typographic considerations.
- *
- * Much less clear is the choice of width for the Not East Asian
- * (Neutral) class. Existing practice does not dictate a width for any
- * of these characters. It would nevertheless make sense
- * typographically to allocate two character cells to characters such
- * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
- * represented adequately with a single-width glyph. The following
- * routines at present merely assign a single-cell width to all
- * neutral characters, in the interest of simplicity. This is not
- * entirely satisfactory and should be reconsidered before
- * establishing a formal standard in this area. At the moment, the
- * decision which Not East Asian (Neutral) characters should be
- * represented by double-width glyphs cannot yet be answered by
- * applying a simple rule from the Unicode database content. Setting
- * up a proper standard for the behavior of UTF-8 character terminals
- * will require a careful analysis not only of each Unicode character,
- * but also of each presentation form, something the author of these
- * routines has avoided to do so far.

+# libsixel (encoder subset, vendored)
+
+Encoder-only subset of [libsixel](https://github.com/saitoha/libsixel) `1.8.7-r2`,
+used by `src/logo/image/` to render the `sixel` logo type **on Windows and macOS**.
+
+## Why this is vendored
+
+Neither MSYS2 nor vcpkg packages libsixel, so on Windows there is nothing to
+`dlopen()` or to link against. The encoder is small and has no external
+dependencies, so the necessary files are embedded instead. The intent is to upstream
+a libsixel package to MSYS2 later and switch to it; until then this directory is the
+source of truth.
+
+macOS *does* have a package — Homebrew's `libsixel` is this very version, `1.8.7-r2`
+(`brew info libsixel`) — but it is deliberately not used. It drags in `jpeg-turbo` /
+`libpng` for the decoder side we never call, and linking it would mean a different
+encoder on each platform. Since Windows needs an embedded copy regardless, one shared
+copy is simpler than two.
+
+## Why only Windows and macOS
+
+Windows loses ImageMagick entirely — its image backend moves to WIC, which decodes
+and scales but cannot *encode* sixel — so it needs an encoder of its own.
+
+macOS does not get ImageMagick either: `ENABLE_IMAGEMAGICK6` / `ENABLE_IMAGEMAGICK7`
+are gated on `LINUX OR FreeBSD OR OpenBSD OR NetBSD OR ANDROID OR SunOS OR Haiku OR
+GNU`, with no `APPLE`, and its image backend is ImageIO. So it shares the same
+requirement.
+
+On every other platform ImageMagick stays, and it already produces sixel through
+its own SIXEL coder. Adding libsixel there would mean a second encoder for a
+capability that already works: one more dependency for zero gain. So `ENABLE_SIXEL`
+is gated on `WIN32 OR APPLE`, and these sources are **not compiled at all** on
+Linux / the BSDs.
+
+Consequence: sixel bytes differ between Windows / macOS (libsixel) and the rest
+(ImageMagick). That is deliberate and accepted — see
+`doc/windows-image-backend.md` decision 9.
+
+## Transparency
+
+The subset is used for its keycolor support. `sixel_dither_set_transparent()` marks a
+palette index as the transparent one; `output_rgb_palette_definition()` then leaves that
+entry out of the palette definition, and `sixel_encode_body()` never puts a keycolor
+pixel into the node map, so nothing is drawn there and the terminal background shows
+through. `src/logo/image/sixel.c` drives this for sources that contain fully transparent
+pixels — it maps those pixels onto a dedicated index one past the quantized palette,
+because keying a *content* colour would also drop every opaque pixel that shares it.
+
+Two things have to line up for the background to actually be transparent: the caller has to
+mark a keycolor, so the keyed pixels are never painted (above), **and** the encoder has to ask
+for a transparent background, so the terminal leaves those unpainted pixels alone instead of
+filling them. The second half is the DCS `P2` parameter — see
+[Local modifications](#local-modifications) item 3.
+
+Note what this is and is not: it is a **palette-index** keycolor, not alpha support. A
+partially transparent pixel has to be drawn in its unblended colour, since a sixel has
+no way to blend with whatever the terminal has behind it.
+
+⚠️ Do not vendor a *newer* libsixel in the belief that this version cannot do
+transparency. It can, and it was measured: the official `1.8.7-r2` omits the keycolor
+entry and leaves the keyed pixels unpainted, with the remaining pixels correctly placed.
+When a transparent background is not showing up, check the caller first — historically
+the caller simply never called `sixel_dither_set_transparent()`, and an image logo only
+renders correctly once it does. If the caller *is* setting a keycolor and the background is
+still solid, check `P2` instead: the keyed pixels are being left unpainted correctly, but the
+terminal is filling them.
+
+## What was kept
+
+Starting from `sixel_dither_new` / `sixel_dither_initialize` / `sixel_output_new` /
+`sixel_encode` and following the dependency closure, only these files are reachable:
+
+| File | Provides |
+|---|---|
+| `tosixel.c` | `sixel_encode`, `sixel_putc`, `sixel_node_*`, DCS envelope handling |
+| `dither.c` / `dither.h` | `sixel_dither_new`, `sixel_dither_initialize`, `sixel_dither_unref` |
+| `output.c` / `output.h` | `sixel_output_new`, `sixel_output_unref` |
+| `quant.c` / `quant.h` | Median-cut palette construction |
+| `pixelformat.c` | `sixel_helper_compute_depth`, `sixel_helper_normalize_pixelformat` |
+| `allocator.c` / `allocator.h` | `sixel_allocator_*` |
+| `status.c` / `status.h` | `sixel_helper_set_additional_message` |
+| `malloc_stub.h` | Included by `allocator.c`; compiles to nothing when `HAVE_MALLOC` |
+| `sixel.h` | Public API (upstream `include/sixel.h`) |
+
+## What was removed
+
+Everything else in the upstream tree, in particular:
+
+- **Decoding**: `decoder.c`, `fromsixel.c`, `frompnm.c`, `fromgif.c`, `frame.c`,
+  `loader.c`, `stb_image.h`, `stb_image_write.*`. Image decoding is done by the
+  platform backend (WIC on Windows, ImageIO on macOS, ImageMagick elsewhere), so
+  libsixel only ever sees an RGBA8 buffer here.
+- **The `sixel_encoder_*` / `sixel_decoder_*` high-level API**: `encoder.c`,
+  `writer.c`, `tty.c`, `scale.c`. These pull in file I/O, terminal probing and the
+  loader registry. We call the dither/output/encode trio directly.
+- **`rgblookup.h` / `rgblookup.gperf`**: a gperf-generated color-name table used
+  only by `encoder.c` for `--builtin-palette` parsing.
+- **`converters/`** (`img2sixel`, `sixel2png`), **`python/`**, **`tools/`**,
+  **`tests/`**, **`images/`** (216 test images), and the packaging templates
+  (`package.json.in.in`, `libsixel.pc.in`).
+- **The autotools machinery**: `configure`, `Makefile.in`, `aclocal.m4`, `m4/`,
+  `ltmain.sh`, `config.h.in`, … See item 2 under
+  [Local modifications](#local-modifications).
+- **Six of the nine `LICENSE.*` files**: `LICENSE.images` / `.mesa` / `.pngsuite` /
+  `.sdump` / `.stb` cover only material that was dropped (test images, the OpenGL
+  example, the `sdump` tool, stb). The three that remain are the complete set
+  required by the files above — verified against each file's own header, see
+  [License](#license).
+
+Result: **20 files / 256 KB**, down from 319 files / 11.3 MB. Note that 8.0 MB of
+that 11.3 MB was `images/` fixtures, so the meaningful comparison is code:
+`src/` + `include/` went from 50 files / 1.17 MB to 20 files / 256 KB.
+
+## Local modifications
+
+Four deliberate divergences from upstream. Re-apply all four when re-syncing.
+
+1. **`sixel.h` — `SIXELAPI` is empty.** Upstream defines it as
+   `__declspec(dllexport)` on Windows. This subset is compiled into `libfastfetch`
+   statically rather than into a standalone DLL, so the attribute would (a) add
+   every libsixel symbol to fastfetch's export table and (b) make `sixel.h`'s
+   declarations disagree with the ones in `dither.h` / `output.h` / `quant.h` /
+   `allocator.h`, which do not carry it (clang warns:
+   `-Wdll-attribute-on-redeclaration`).
+
+2. **`config.h` is hand-written.** Upstream generates it with `configure`. Only
+   these vendored files read it, and they reference a small fixed set of macros,
+   so the values are hard-coded. Two things to watch:
+   - `HAVE_TESTS` must stay **undefined**, not `0`: `sixel.h` gates its test-only
+     declarations with `#ifdef HAVE_TESTS`, so `#define HAVE_TESTS 0` would still
+     pull in declarations for functions we do not compile.
+   - `HAVE_MEMORY_H` / `HAVE_STRING_H` must be `1`. fastfetch builds with
+     `-Werror=implicit-function-declaration`, so a missing `<memory.h>` /
+     `<string.h>` include in `pixelformat.c` / `status.c` is a hard error.
+
+3. **`tosixel.c` — the DCS `P2` parameter is initialised to 1.** `sixel_encode_header()`
+   declares `int p[3] = {0, 0, 0}`, and the trailing-zero trimming right below it then drops
+   all three, so the envelope is a bare `ESC P q`. That means `P2 = 0`, which tells the
+   terminal to fill every unset pixel with **colour-table entry 0** — and that entry is
+   defined by the image's own palette, so a keycolor image comes out with a solid rectangle
+   behind it rather than transparency. Setting `p[1] = 1` leaves unset pixels untouched.
+
+   The trimming still drops the trailing aspect-ratio parameter, so the envelope is
+   `ESC P 0;1 q`. `P3` defaults to 0 and the two spellings are equivalent — verified by
+   decoding both with libsixel's own decoder and with ImageMagick's. ImageMagick's SIXEL
+   coder and chafa both write `0;1;0` explicitly.
+
+   This only shows up on a terminal that implements the VT340 background rule. Windows
+   Terminal does (`_backgroundFillRequired = (_conformanceLevel == 1 || !transparent)` in
+   `src/terminal/adapter/SixelParser.cpp`), which is where it was reproduced; WezTerm does
+   not fill, so the identical bytes look correct there. It is also why Linux never showed
+   the problem: that path goes through ImageMagick, which already sends `P2 = 1`.
+
+4. **`output.c` — release the allocator reference if output allocation fails.**
+  `sixel_output_new()` creates an allocator or takes an additional reference before
+  allocating the output context. If that allocation fails, the reference is not owned by
+  an output object and must be released before returning `SIXEL_BAD_ALLOCATION`.
+  Fastfetch passes a null allocator, so without this cleanup the newly created allocator
+  becomes unreachable on this error path. The successful path and returned error code are
+  unchanged.
+
+The vendored sources are also exempted from `-Wconversion` in `CMakeLists.txt`:
+upstream has ~160 implicit int→`unsigned char` narrowing warnings. Everything else
+(`-Wall -Wextra` and fastfetch's `-Werror=` set) applies unchanged, and the subset
+compiles clean.
+
+## Re-syncing with upstream
+
+```sh
+VER=1.8.7-r2
+git clone --depth 1 --branch "$VER" https://github.com/saitoha/libsixel /tmp/libsixel
+
+# 1. copy the closure (paths change from src/foo.c to foo.c, include/sixel.h to sixel.h)
+for f in tosixel.c dither.c dither.h output.c output.h quant.c quant.h \
+         pixelformat.c allocator.c allocator.h status.c status.h malloc_stub.h; do
+    cp "/tmp/libsixel/src/$f" .
+done
+cp /tmp/libsixel/include/sixel.h .
+cp /tmp/libsixel/LICENSE /tmp/libsixel/LICENSE.sixel /tmp/libsixel/LICENSE.pnmcolormap .
+
+# 2. re-apply the four local modifications listed above
+# 3. verify
+```
+
+Verification (must be 0 diagnostics, and the encoder must emit a DCS-wrapped stream).
+Both platforms compile this subset, so run it on both:
+
+```sh
+# Windows: CC=/c/msys64/clang64/bin/cc.exe
+# macOS:   CC=cc   (verified with Apple clang 21: 0 diagnostics)
+CC=cc
+FLAGS="-I. -Wall -Wextra -Wconversion -Wno-conversion -Werror=uninitialized \
+ -Werror=return-type -Werror=vla -Werror=incompatible-pointer-types \
+ -Werror=implicit-function-declaration -Werror=int-conversion -std=gnu23"
+for f in tosixel dither output quant allocator pixelformat status; do
+    $CC $FLAGS -c $f.c -o /dev/null || echo "FAILED: $f"
+done
+```
+
+If upstream adds a call from the closure to a new file, the build fails at link
+time with an undefined `sixel_*` symbol — add that file and repeat.
