+**Ad-hoc identity compatibility repair (2026-08-23):** the surviving project
+instruction templates prescribed fleet-wide `ADHOC-YYYY-MM-DD` identifiers.
+Activity Core and Net Kingdom used that form on the same day, and deterministic

+validator now accept and prescribe `{WP_PREFIX}-ADHOC-YYYY-MM-DD` while keeping
