Declare a third operator address; record T02 progress and why full converge was held

89.244.90.255 appeared in the live allowlist mid-session. Verified legitimate:
SSH pubkey auth as tegwick from that address on 2026-08-02, and UFW BLOCK
entries on 6443 immediately before it was granted. Now declared.

Both stale grants are deleted from the live host, so the security goal of T02 is
met and the live 6443 allowlist matches the declaration exactly.

Full convergence deliberately held: --check reports 11 changes, mostly unrelated
to the firewall, including MemoryMax=1500M on user-1000.slice which could OOM
running agent workloads, plus an sshd restart. That is a separate decision, and
the base role has no tags so convergence cannot be scoped to UFW alone. Records
both follow-ons.

The allowlist drifting again by hand during the session that was fixing
allowlist drift is now recorded as the strongest argument for T04, removing the
API from the public internet.
