scr_runtime.h now includes 48 module headers (scr_core.h, scr_rc.h, scr_string.h, scr_dyn.h, scr_http.h, ...) in dependency order and holds no declarations. Each module header holds whole sections of the former file, includes the headers whose names it uses, and compiles on its own. Declarations, macros, struct layouts and inline bodies are unchanged. Five blocks move to join their module: the class-hierarchy vtable header (into scr_error.h, after the string core), the node:timers/promises pair (into scr_async.h), the JSON.parse entry points and the JSON output buffer (into scr_json.h, after the dyn declarations) and the EventTarget block (after scr_json.h). No moved block uses or declares a name that a block it moves past uses or declares. The string methods keep their position after the class objects in scr_string_methods.h, because their struct ScrDyn parameters rely on the file-scope struct ScrDyn declaration there. The runtime ABI scan reads scr_runtime.h with its module headers expanded in include order. A runtime test compiles every module header on its own. scripts/runtime-header-hunks.mjs retargets a diff of the single-file header onto the module headers.
