tegwick 5697669063 research: Trilium (TriliumNext) deep dive (note cloning/DAG hierarchy, attribute inheritance, HTML-native); UC-66/67

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.

SCOPE

One-Liner

Git-based Markdown wiki orchestrator and federation layer — early-stage scaffold with intent, research, and specification groundwork; domain model not yet implemented.

Mode Of Operation

Close the gap between this file and INTENT.md by exploring the problem space (research/), reviewing inbound demand (demand/), refining specifications (spec/), and implementing through registered workplans (workplans/). Learnings update both SCOPE and INTENT where necessary.

Current Status

Layer	State
Code	Python package scaffold (`src/shard_wiki/`, smoke tests only)
Intent	`INTENT.md` established; authorization-in-core amendments drafted
Research	yawex prior art; c2 origins; federation concepts; wikiengines overview (`research/260608-/`); XWiki/TWiki/Foswiki deep dives (`research/260613-/`); Xanadu + ZigZag + Roam + Obsidian + Notion + Joplin + Logseq + local-first workspaces (Anytype/AFFiNE/AppFlowy) + Trilium deep dives & shard-spectrum synthesis (`research/260614-*/`)
Demand	NetKingdom integration asks captured, not yet negotiated
Spec	Architecture blueprint drafted; UseCaseCatalog 67 UCs from research; PRD/TSD scaffolds
Work	`SHARD-WP-0001` active (6 tasks); `SHARD-WP-0002` active (16 tasks: T1–T10 federation + T11–T16 adapter contract)

In Scope (today)

Establishing repository documentation structure and specification groundwork.
Federation design informed by yawex prior art (page resolution, namespaces, derived views, provenance, overlays).
Authorization model design (delegated authentication, core authorization).
Shard adapter contract and wiki page model (to be specified, then implemented).
Git-backed coordination journal for information spaces.
State Hub workplan registration and consistency sync.

Out Of Scope (today)

A standalone wiki engine UI or rendering pipeline.
Authentication, credential storage, or user directory implementation.
Hard-coded editorial, sync, or conflict-resolution policy.
Generic file mirroring independent of wiki-page semantics.
Production deployment, multi-tenant operations, or enterprise IAM rollout.

Boundary Rule

shard-wiki orchestrates wiki-shaped content across heterogeneous shards. It provides mechanisms (federation, projection, overlay, patching, reconciliation); policy (canonical source, conflict preference, access rules) remains explicit and configurable. Identity comes from pluggable providers; authorization decisions live in core.

Current Planning

Design work is tracked in workplans/SHARD-WP-0001-yawex-requirements.md (yawex-derived resolution, namespaces, overlays) and workplans/SHARD-WP-0002-federation-architecture.md (federation architecture, decisions, tradeoffs). Specification outputs land in spec/. Inbound integration asks remain in demand/ until reviewed and promoted into spec or workplans.
