The neuron fires on programming‐style tokens—things like namespaced identifiers (e.g. “ios::”), compiler flags and settings (e.g. “-O3”, “std=c99”), protocol or API version strings (e.g. “HTTP/1.1”), and library/function calls—essentially spotting code syntax bits rather than natural language.
technical code and web syntax fragments, especially identifiers or paths that include symbols like slashes, dashes, underscores, or double colons (e.g., file paths, URLs, namespaces, flags, and CSS/module names).
