Captain Bob: "give frames IDs and call by ID" -- frames stack per VM, each
with an ID. New vm_frame.h/.c: VMFrameEntry { VMFrameID id; VMUuid vm_id;
kind (INTERPRET/DRAIN/IDLE) }, a growable VMFrameStack embedded as VM.frames
(reserved at birth, freed in vm_cleanup, grown by allocate-copy-free).
vm_interpret() -> vm_interpret_kind() pushes a frame onto the running stack's
owner, holds only its ID, fails closed if it cannot grow, and pops by ID
(mismatch reported as VM FRAME CORRUPTION).
The Stage A/B loose fields are gone and everything is derived from the stack:
- ownership gate: one frame, and it is vm's own
- drain guard: a DRAIN frame for vm already on the running stack
- parked-idle: an IDLE frame the trampoline pushes around its yield
- log attribution: the top frame's vm_id, resolved by ID through the registry
The single saved-and-restored attribution global is removed.
Evidence: the probe baseline on the pre-frame code read HSSAS (the global
named Hestia while Hera resumed). With frames it reads HSHAS on all three
ISAs, with Hestia's top frame IDLE and Hera's frames back to 0; the probe is
reverted. Formal acceptance on all three ISAs: dict_hash identical and
unchanged, zero UNKNOWN WORD, faults, frame corruption or refused interprets,
and the WIREBIND relay 1 2 + . -> 3 works.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
