Extends the capability model to the nine WP-0003 engines (~23 systems total). Per-shard spectra 13 -> 14 (adds provenance granularity); refines merge-model (+fork/journal-replay, +coexist-with-rank), attachment-mode (+git-IS-store, +container, +direct-DB, +REST/file-store-hybrid, +external-API payload-format facet), native-query (+SPARQL/RDF far-end), history (+DB-rows, +partial), structure (+typed-graph, +inline-embedded objects), content-opacity (+lossy-exportable), write-granularity (+story-item, +section-anchor). Headline: new federation-model taxonomy (S2.5) -- federation is plural (fork+journal / VCS-replication+ping / query-time graph join / feed aggregation / activity streams / engine-mirror), a selectable/composable coordination-layer axis feeding SHARD-WP-0002 T1-T6. Folds UC-68-82 into the workplan; no new UCs, no INTENT boundary change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# 260614 — Shard spectrum synthesis (one capability model across the full dive set)
|
||
|
||
Date: 2026-06-14 · **revised 2026-06-14 (v3)**
|
||
|
||
## What this is
|
||
|
||
A **synthesis** (no new external research) that reads every studied system *across* the
|
||
others and distills them into a single comparative model feeding the **shard adapter
|
||
contract** and the **federation track** (`SHARD-WP-0002`).
|
||
|
||
**v3** extends the model to the **SHARD-WP-0003 engine batch** (Federated Wiki, Wikibase/
|
||
Wikidata, the git-forge wikis Gitea/GitLab/GitHub, TiddlyWiki, ikiwiki, Salesforce Quip,
|
||
MojoMojo, Oddmuse, UseModWiki) — ~23 systems in all. Per-shard spectra grow from thirteen to
|
||
**fourteen** (adds **provenance granularity**), and a **new coordination-layer axis** is
|
||
introduced: the **federation-model taxonomy**.
|
||
|
||
Centerpieces:
|
||
- **The shard family matrix** — every candidate backend × {substrate, attach mode(s),
|
||
addressing, structure, history, merge, query, →Markdown, opacity}, with Xanadu/ZigZag as
|
||
ideal anchors and Federated Wiki as the federation-model anchor. v3 adds the flat-file
|
||
floor (Oddmuse/UseModWiki), git-IS-store (forge wikis/ikiwiki), TiddlyWiki, MojoMojo
|
||
(direct-DB), Quip (external-API/HTML), and Wikibase (typed-graph far-end).
|
||
- **The fourteen capability spectra** — the claim that the adapter contract should model
|
||
*positions on spectra*, each anchored at both ends by a real system, with federation ops
|
||
degrading by position. v3 adds **provenance granularity** (14th: per-shard → per-page →
|
||
per-edit → per-statement/value), and refines merge-model (+fork/journal-replay,
|
||
+coexist-with-rank), attachment-mode (+git-IS-store, +container, +direct-DB,
|
||
+REST/file-store-hybrid, +external-API payload-format facet), native-query (+SPARQL/RDF
|
||
far-end, +filter mid), history (+DB-version-rows, +partial/truncated), structure
|
||
(+typed-graph, +inline-embedded objects), content-opacity (+proprietary-lossy-exportable),
|
||
write-granularity (+story-item, +section-anchor).
|
||
- **The federation-model taxonomy (§2.5, new)** — federation itself is plural: fork+journal
|
||
(Federated Wiki), VCS-replication+ping (ikiwiki), query-time graph join (Wikibase SPARQL
|
||
`SERVICE`), feed aggregation, activity streams, engine-mirror (Wiki.js). A
|
||
selectable/composable coordination-layer axis feeding **T1–T6**.
|
||
- **UC-44–UC-82 → workplan task mapping** (T1–T6 + T11–T16).

|
||
## Status
|
||
|
||
Synthesis v3 complete. No new use cases (consolidation only). Feeds `SHARD-WP-0002`:
|
||
**T1–T6** federation-model taxonomy (selectable/composable federation); **T11** reframed
|
||
around the **fourteen spectra** (incl. provenance granularity + expanded attachment modes +
|
||
external-API payload-format facet); T12 page-model breadth (prose + typed/computed records +
|
||
**inline-embedded objects** + **typed-graph statements** + non-Markdown assets +
|
||
query-defined + multi-placement/DAG identity); T13 history (DB-rows + partial-flat-file =
|
||
supplement; completeness metadata; **journal-shaped** coordination journal); T14 **full
|
||
attachment taxonomy** (git-IS-store / container / direct-DB / REST-file-hybrid +
|
||
source-of-truth per binding); T15 lossy + **not-Markdown** (graph/HTML); T16 (addressing
|
||
incl. statement GUID + **opaque stable identity**, identity≠placement, derived index,
|
||
**graph query / federated SERVICE**). UC coverage extended UC-34–UC-67 → **UC-34–UC-82**.
|
||
|
||
**New through-lines (v3):** federation is plural (the federation-model taxonomy); provenance
|
||
has a granularity spectrum (down to per-statement, Wikibase rank/references); git is both the
|
||
home store and the home journal (forge wikis make git *the* store, resolving the engine-
|
||
mirror write-race); the flat-file floor (Oddmuse/UseModWiki, Wikipedia's MediaWiki Phase I)
|
||
is the field's common root and the minimal capability profile; the page model must also carry
|
||
typed-graph statements and inline-embedded objects.
|
||
**Carried from v2:** CRDT changes the merge math; identity ≠ placement; metadata can be
|
||
computed; content opacity is per-item; the attach surface is not always the native store; the
|
||
block-graph-on-files sweet spot (Logseq `id::`).
|
||
**Carried from v1:** files-canonical/index-derived; fine-grained addressing is adoptable;
|
||
transclusion=clone=embed=reference is one primitive; structure/history federate iff in-text;
|
||
attach mode is per-binding; the platform can enforce no-silent-mutation.
