kb_text_shape (v2.10, JimmyLefevre) had been LOST from the sx tree — ffi/stb_truetype.sx referenced repo paths that no longer existed (and nothing runs glyph_cache, so the dangling unit never fired). The trimmed copy returns from the m3te project as a proper vendor: curated c/kbts_api.h decls over the full upstream header, README with provenance, and examples/1627 pinning context + font creation so the unit compiles and runs in-suite. file_utils (in-house asset-read helper with the Android AAssetManager hook) gets the same unit shape. modules/ffi/stb_truetype.sx is gone: glyph_cache imports the three vendored units (stb_truetype, kb_text_shape, file_utils) directly.
