FABRIC-3.5 SXXXII, closing FABRIC-3 SXXIX bug 2 (SXXXVI). A send marks the receiver for the switch signal; the VM's own loop on its native stack takes its messages and yields; Hera's idle beat makes the pending switch instead of running other VMs' messages on her stack; every VM gets switcher turns from birth; the drain refuses any call outside the VM's own context (the test: it held every relayed line before, none now). Found on the way: amd64's first-entry frame left rsp 8 bytes off the SysV entry alignment (#GP on the first interpreter run on a VM's own stack), and a VM yielding from its loop was marked SWITCHED_OUT, which stopped console relay after one message and would have made KILL refuse it. Relay of four lines to a WIREBIND identity on all three ISAs, five hot-plugged identities, and standard acceptance (POST 1052, hash 0x08873e0f44b7cb2a) all pass.

arena.h— the capsule arena allocator: fixed-region allocation for capsule payload data, separate fromkmalloc's general kernel heap.parity.h— the birth/execution parity-record logger: declares the logging interface used to record VM ID, capsule content hash, and dictionary hash on every capsule birth, enabling offline determinism verification across independent kernel runs.
