Complete callable Close REST API suite: all 297 method/path operations in the current official OpenAPI plus the official Advanced Filtering search documented outside that explicitly experimental specification. The compatibility root keeps all 26 prior operation IDs, wire routes, and shipped workflows while five dependency packs carry 272 additional operations. The OpenAPI and three pagination/advanced-filter authorities are hash-anchored; generation fails closed on drift. JSON responses preserve unsafe integers as exact decimal strings. Reads are approval-free; mutations are grant-off and approval-gated, with destructive, administrative, communication, automation, enrichment, and bulk changes requiring approval every run.
