+| `opcodes_build.py` | Generator + linter for the opcode reference. `--bootstrap` appends entries observed in the Himegari corpus; `--bootstrap-age` appends every missing opcode from the pristine 548-entry AGE catalog as an unobserved compatibility stub. Catalog stubs retain Kelebek's ABI label/argument count so other AGE scripts decode past them, but remain `noop_headless=false`: the VM currently traces/skips them, while coverage continues to report them as unresolved rather than semantically safe. | `--build` · `--lint` · `--bootstrap` · `--bootstrap-age` | `vm-map/opcodes.toml` → ⚙ `tools/age_opcodes_himegari.py`, ⚙ `build/opcodes.json`, ⚙ `docs/opcode-reference.md`, ⚙ `build/opcode-coverage.md` |
