VM-STEP/VM-EXEC/VM-CALL (5 sites) gained console_println() diagnostics
matching their own existing sibling guards.
SWITCH-MARK-WORK and VM-HEAT (3 sites) resolved per §XXXII.3's own
recommendation: dropped vm->error entirely rather than diagnosing it,
matching each function's own doc comment ("must never error or spam
the console" / "does not print/error"). SWITCH-MARK-WORK is the same
function §XXVIII.3 already fixed once for an off-by-one that fired
silently on every MSG-SEND in the system -- the guard now genuinely
cannot repeat that by contract, not just by the threshold being right.
VM-HEAT's guards now push 0 and return, matching its own
always-returns-a-value stack effect.
Three-arch clean qemu acceptance passed. Zuse's own WIREBIND attach
(every boot) drives MSG-SEND -> SWITCH-MARK-WORK, so this batch's most
safety-critical fix is exercised by standard acceptance, not just
compiled.

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.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
