WARDEN-WP-0044-T02: warden case plan; close WP-0044-T01 and WP-0043-T02

warden case plan resolves an accepted, materialized SecurityCase against its
acknowledged type: warden, attended and owner steps, type defaults, conditions,
rendered entry points and verification. Executes nothing; refuses unmaterialized
cases, missing or unreviewed lanes and secret or type-fixed parameters.

T01 closes on net-kingdom's R8 option 1 and the founder's acknowledgement of
the type (memo r4). WP-0043-T02 closes on railiance-platform b77cb41.
