## 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.

research: Notion deep dive (closed block-DB SaaS, external REST API only, database-as-pages); UC-57/58/59
The closed/hosted/schema-rich extreme: everything is a block (UUID id,
type, properties, ordered child content, single parent), pages are blocks
and database rows are pages with a schema, Postgres-backed hosted SaaS.
Databases add typed properties + relations + rollups + formulas across
many views = the apex of wiki-page-as-structured-record. Extension model
has no in-app plugin runtime; the only extensibility is the external REST
API (+ webhooks 2026) inside a tight envelope (~3 rps, eventual
consistency, recursive child fetch, scoped/revocable per-page grants).
Adds the third attachment mode (external-API-only) alongside file-store
(Obsidian/TWiki) and in-engine host (Roam/XWiki); Notion enforces no
silent remote mutation via scoped grants. Added UC-57 (attach closed
external-API-only shard w/ operational envelope + scoped grant), UC-58
(typed database w/ schema+relations+views, no flattening), UC-59
(lossy-aware translation w/ fidelity report); enriched
UC-31/34/36/39/50/51/52/54/56. Boundary: one external-API candidate shard,
best as projection/mirror/overlay/backup, not a substrate and not the
federation layer.

synthesis: shard spectrum across nine systems; fold into SHARD-WP-0002 (T11 eleven spectra, new T16)
Cross-dive synthesis (research/260614-shard-spectrum-synthesis/) reading
the two Nelson conceptual systems, four engines, and three modern tools
across each other: a shard family matrix and eleven capability spectra
(addressing, content identity, structure, history, native query,
translation, attachment mode, operational envelope, access grant, write
granularity, content types) — positions anchored at both ends by a real
system, federation ops degrading by position. Through-lines:
files-canonical/index-derived wins; fine-grained addressing is adoptable;
transclusion=clone=embed is one primitive; structure/history federate iff
in-text; attach mode is a per-binding choice; Notion proves the platform
can enforce no-silent-mutation.
Folded into SHARD-WP-0002: T11 reframed around the eleven spectra; T12
page model stretched four ways (prose + typed records + non-Markdown
assets + query-defined); T13 adds Notion supplement; T14 rewritten as the
three-mode attachment taxonomy (file-store / in-engine-host /
external-API); T15 adds lossy-with-fidelity-report; new T16 (addressing,
content identity, dimensional/query navigation). UC coverage UC-34-43 ->
UC-34-59. Workplan now 16 tasks. No new UCs (synthesis only).

## 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
|
|
|
|
|
|
|
2026-06-08 14:55:13 +02:00
|
|
|
|
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.
