Extends the REPL prompt to "[VM name] (user) ok>" (e.g. "[Hera] (zuse) ok>") per the locked FABRIC.md §4.4s spec, unblocked by this session's own §I.3/§I.8 identity-tracking work. Adds capsule_wirebind_attached_username() alongside the existing tracked VMUuid, and a new sk_print_prompt() helper (repl.c) that all three prompt call sites now go through -- checks Zuse first, then a WIREBIND user, prints nothing when neither is attached. Closes 4.4s, 4.3 (console umbrella), and formally settles 1.11 (dirty-event granularity) as region-based per FABRIC-2.md's own "no independent path" ruling -- a decision closure only, not an implementation, so §17.4 (framebuffer heat/decay physics) stays open, re-scoped precisely: blocked on the dirty-region-tracking mechanism existing, not on 1.11's decision. Documents a reported-but-unreproduced terminal defect (§I.9) as a new punch-list item -- investigated the readline/keyboard-bridge code paths, found nothing conclusive, needs a live repro with a serial log before it's actionable. Verified 3-arch boot to ok> (amd64/aarch64/riscv64, each in the foreground); logs and DoE CSVs from this session's verification runs included per this repo's own audit-artifact convention.

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.
