research: Trilium (TriliumNext) deep dive (note cloning/DAG hierarchy, attribute inheritance, HTML-native); UC-66/67

Browse Source 
SQLite-local PKB whose standout is note cloning — a single note can sit in
multiple tree locations at once via the note (identity) vs branch
(placement) split, so the hierarchy is a DAG, not a tree, with no single
canonical path. The identity-not-equal-placement model is the clean way to
represent a page in multiple locations/shards and the namespace-level form
of the clone/reference primitive. Also: attributes (labels + typed
relations) are inherited + templated, so metadata is computed (own +
inherited + template), not a flat bag; content opacity is per-item
(per-note encryption / protected notes), refining the proposed 12th
spectrum; HTML-native (CKEditor, lossy to Markdown); dual extension
surface (scripting code notes + ETAPI token REST). TriliumNext is the
active community fork of zadam's Trilium (TWiki->Foswiki pattern). Added
UC-66 (DAG hierarchy / note cloning), UC-67 (inherited/templated
attributes, effective vs own); enriched UC-15/22/34/38/42/61. Catalog now
67 UCs. Architecture for SHARD-WP-0002 T11/T12/T14/T15/T16: DAG namespace
+ identity/placement split, computed/inherited metadata, per-item content
opacity, HTML source model, scripting + ETAPI host surfaces.
