capsule_birth.c's generic admission block now registers a session for every born VM (session_register) and pins it (session_set_pinned) when the birthing capsule is Hera/Hermes/Artemis. Bug found and fixed via a temporary probe (written, run, captured, reverted): the fleet-foundation name check first used an exact-match comparison against "Hermes"/"Artemis", but capsule_name is actually "hermes:init.4th"/"artemis:init.4th" (the real namespace:filename convention) -- the check silently never matched, both would-be-pinned VMs stayed unpinned. Fixed with a new vm_name_prefix_eq_nocase() helper matching everything before a literal ':'. Probe confirmed pinned=0 before the fix, pinned=1 after, on all relevant VMs. Session.parent is hardcoded to vm_uuid_hera() for now (every birth through this path is Hera-initiated today); step 7 generalizes this to the actual birthing VM's own id. Verified 3-arch boot to ok> (amd64/aarch64/riscv64) on the final, probe-free code. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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, …) |
