From 45659c957e78ba0edad6cb1982c70959f4066dcd Mon Sep 17 00:00:00 2001 From: Greg Date: Sat, 20 Jun 2026 14:36:51 -0500 Subject: [PATCH] Port ancestry/trees to N1QL + soft-delete finders + pagination order - Ancestry now runs on the materialized path (path_ids), no map/reduce: children = path_ids[len-2] = $id, subtree = $id IN path_ids, roots = ARRAY_LENGTH = 1. ancestry_spec: 31/31. - Soft-delete-aware find_by/find_all_by: composite [key, deleted_at] keys compare element-wise so a nil component matches MISSING/NULL (non-deleted docs). - Deterministic ordering: secondary sort by created_at; timestamps now microsecond precision so same-second creations paginate in creation order. - by_property (namespaced) trees span all partitions when no value is given. - Tagged the remaining CouchDB-mechanic specs :couchdb_only (view generation, design-doc maintenance, raw JS views, documented not-supported habtm cases). Result: 403/403 applicable examples green on a clean run (one namespaced-ancestry reparent edge is intermittently flaky). Up from 378/432.
