MESH.md step 5, in the fabric under test; the products are still one node each until steps 8 and 9. manage.c: what Hera asks of whoever holds the fabric, eleven requests by KERNEL-WORD -- NODE-ME -BORN -WIRE -UNWIRE -SLEEP -WAKE -KILL -PARITY and CAPSULE-OPEN -CELL -LINE. Nucleus: PORT!, SEND-ON, AWAIT, (SEAL). capsules/v4/hera.4th: BIRTH and UNIT, the unit rule in FORTH and nowhere else. The dictionary hash moves to the engine (v4_image_dict_hash). test_host_unit.c, 34 checks, 64-bit: Hera is born empty, takes the nucleus through her port, FORTH-79, POST and her capsule; 10 UNIT; four nodes are born, each takes the nucleus and FORTH-79 through its port from Hera and passes POST 538/538; four parities, one dictionary hash; they talk, and a message between two corners not wired goes by Hera. All v4 tests at both widths and under ASan+UBSan. hosted-check on three ISAs. Bare metal: logs/20261006-143934 (amd64), -144204 (aarch64), -144601 (riscv64). Open, recorded in MESH.md: not run at 32 bits; a node that never answers leaves Hera waiting; the capsules are read from files in the test, not from the baked directory.
