Walk the extracted libretro tree and build the list of installable candidates (those that pass the cheap pre-filters AND the transpile gate AND don't

Locate the directory that contains config.yml (the integrated extraction config plus yamls/us/*.yml recipes used by standalone Torch.

String getters still need the lock, but they are incredibly fast now

The URL is spliced into a curl command line, so reject anything that could escape the quoting or smuggle extra arguments. Release asset URLs are plain

True if `stem` looks like a multi-pass component (`crt-foo-pass0`, `tvout-tweaks-pass-1`, `interlaced_pass2`). These are partial shaders driven by a .

A libretro single-file shader is recognizable by the VS/FS-half preprocessor guards. The PostProcessGlslNormalizer relies on these to split the file i

Read a candidate shader file into memory. Returns the empty string on read failure — caller treats that as "not installable" without having to disting

Read a zip member fully into `out`. Returns false on any libzip error, an out-of-range member size, or an allocation failure.

Reject shaders that derive their output from libretro multipass- history bindings (`PassPrev<N>Texture`, numbered `Pass<N>Texture`). Our auto-bind pre

Run a child process with stdout/stderr redirected and no console window. Required on Windows because _popen() / system() shell through cmd.exe; when c

Shell out — every platform we ship has curl on $PATH (macOS, modern Windows, every desktop Linux distro), and the Updater already depends on it.

We unzip to a scratch directory rather than streaming with libzip to keep this downloader's dependency surface flat (libultraship links libzip private

Enumerate a .zip's entries and index every member whose basename matches the pack grammar. The central-directory read is one shot — far cheaper than t
