G12 dc1: edge bootstrap + v4 addressing COMPLETE (D-112c + D-113a2 proven on 26.7) ...

Edge phase for vr1-dc1, resuming the 2026-07-22 close handoff:
- D-112(c) console bootstrap: SSH + dc1 edge key materialized (payload
  needed util.inc/shell_safe() -- dc0 lesson iv the .b64 artifact lacked)
- key-only SSH verified (15.1-RELEASE-p1)
- D-113(a2) API key minted via vendor model; GET core/firmware/status
  exit 0, product_abi 26.7
- edge addressed: WAN 172.30.3.2/24 gw 172.30.3.1 (egress 0% loss),
  LAN -> 10.12.64.1/22 (ruled provider-public gw), API at new LAN
- interim reach leg removed; rack provider-public leg 10.12.64.2/22 live
- creds consolidated to ~/vr1-dc1-creds/ (creds-audit CLEAN); rack edge-key
  copy shredded -> SEC-015 (transient, remediated)

Two queued findings: bootstrap .b64 missing util.inc; opnsense-bootstrap-apikey.sh
scp transient post-restart-sshd failure (readiness-wait/retry candidate).

CURRENT-STATE G12 row + security-ledger SEC-015 + manifest updated (GA-R1/C1).
