Per FABRIC-3.md D.7 (birth-by-message-only): the Tripod legs must be alive session-less before any thumbdrive-attach flow has a running Hermes/Artemis to message. kernel_main.c's item 4.2/4.6 self-tests previously birthed both, exercised diagnostics, then explicitly KILLed them before ok> every boot -- production boot never actually kept either alive. Stripped both blocks down to birth-only, diagnostics and KILL removed. Found and fixed a real regression this surfaced, not left broken: Hermes's CD-INIT (message/channel arena init, and the thing that loads lib.4th into her own dictionary) was only ever invoked by the self-test just removed -- nothing in hermes/init.4th itself called it. Added an unconditional CD-INIT call at the end of her own init.4th so a real birth actually initializes her arena, matching how Artemis's own ART-BOOT-ENTRY already runs unconditionally at her own capsule load. Added STARTUP-BANNER (lib.4th): a shared word reading a common IDENTITY-BANNER buffer, printing "(no identity)" until CERTVERIFY/MINT exist to populate it from a thumbdrive's PKI fields -- scaffolding only, per direct instruction. Wired into each Tripod leg's own init.4th (Hera/Hermes/Artemis); Artemis didn't load lib.4th before, added that too. Verified live on all three architectures: BIRTH for both, no KILL anywhere in any log, and an interactive USE round-trip confirmed Hermes is genuinely reachable post-boot, not just logged as born.

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.
