The reply leg (Artemis -> Hera ack) that used to flow through
common:messaging.4th's MSG-SEND/MSG-TICK now goes through
kernel-Hermes's sk_hermes_send_one()/sk_hermes_drain_checkpoint()
instead -- FORTH Hermes never sees a BLK-ATTACH-EVENT message again
(SXXXIV.2's partition rule). The request leg was never real FORTH
messaging traffic to begin with (a direct VM-EXEC, no type tag,
forced by Hera's own inability to load common:messaging.4th), so it
is untouched.
New KH-BLK-ATTACH-SEND (repl.c) wraps sk_hermes_send_one(), reached
from capsules/artemis/init.4th's HERA-BLK-ATTACH-REQ. Delivery reuses
task 3.4's already-wired sk_hermes_drain_checkpoint(); BLK-ATTACH-ACK
itself is unchanged, just reached by a different layer.
SK_HERMES_MSG_TYPE_BLK_ATTACH deliberately reuses BLK-ATTACH-EVENT's
own value (9) to document this as a cutover of the same message, not
a new one.
Two real bugs found on the way, both recorded in FABRIC-3.6.md's
findings log:
- A popped FORTH CREATE-buffer address was raw-cast to a host pointer
instead of going through vm_ptr() -- silently read all-zero memory,
no crash, no error, just a message that arrived and did nothing.
Fixed; the rule and its exception (repl.c's own dev-addr is
legitimately a raw pointer, formatted that way by its own pushing
code) are written up for the next FORTH-facing C word.
- A separate, genuine hang on the very first live exercise of this
path, never reproduced across ten subsequent boots. Reported, not
chased -- not blocking, per the task's own check being otherwise
fully satisfied.
Also found live: log_message() is invisible in this build's actual
serial-log capture at every level -- settled on a single
console_println in the real drain target instead, one line per real
USB attach, not a hot-path.
Final acceptance (logs/20260922-105501, -105758, -110304, disk images
reset before each): dict_hash identical across all three
architectures for every VM, zero UNKNOWN WORD, mkcapsule --lint
clean, real ledger+stadium_conserved(Artemis)=true evidence on every
boot.
