A from-scratch fork of simply_couch's model layer that runs on Couchbase natively: `include SimplyBased::Model` instead of `include SimplyCouch::Model`. - SimplyBased::Store replaces the CouchDB layer: KV documents, N1QL/SQL++ finders + lazily-created GSIs, CAS mapped onto _rev. No design documents or JavaScript map/reduce — the hand-written association views become N1QL (belongs_to/has_many/has_one scalar FK; habtm via ANY ... SATISFIES + array index, or KV multi-get on the storing side). - Redis replacements on the same cluster: Counter (atomic increment/decrement), Cache (ActiveSupport::Cache::Store over KV+TTL, drop-in Rails.cache/ActiveJob), Lock (insert-if-absent + TTL + CAS-checked release). - Runs the simply_couch test suite against live Couchbase: 378/432 applicable examples green (CouchDB-mechanic specs tagged :couchdb_only and excluded). - Remaining: ancestry (tree) + embedded_in reverse-lookups (recursive/embedded N1QL) and a few pagination/lifecycle edges.
