Hera can't message: root-caused and fixed by symmetry (FABRIC-3.md §XX)

Browse Source

Hera never loaded common:messaging.4th, unlike every other VM in the
fleet. The standing belief was this was deliberate, to avoid moving
her dict_hash off baseline. Checked live instead of assumed: loading
messaging.4th into her dictionary silently dropped every colon-
definition referencing one of 8 STADIUM-* primitives that
register_child_vm_words() gives every other VM but
register_mama_forth_words() never gave her -- a missing-primitive gap,
not a designed privilege boundary. Confirmed mama_word_birth is
genuinely VM-agnostic and SPAWN-EVENT is an unwired placeholder before
proposing the fix.

Fix: register the same 8 STADIUM-* primitives for Hera, load
messaging.4th from init.4th the same way Hermes/Artemis/console/mint
already do, and give her own idle-loop context a direct MSG-TICK call
(not VM-EXEC, which would hit the same reentrancy class the existing
per-other-VM pump loop already guards against) so her own queued
messages actually drain. Her dictionary is now a proper superset of
every child VM's, plus her remaining extra privileges -- not
structurally different from any other VM, just additionally
privileged.

Verified: dict_hash identical across amd64/aarch64/riscv64
(0xc8f4b09e36f4fc4a), Hermes/Artemis dict_hashes unchanged and still
cross-arch identical, all three boot clean to zuse)ok> with zero
UNKNOWN WORD faults, mkcapsule --lint clean.

Unblocks rewriting the turn-attractor (FABRIC-3.md §XIX) to coordinate
via real MSG-SEND/MSG-TICK instead of blocking VM-EXEC.
