# 260614 — Federated Wiki deep dive

Deep dive on Ward Cunningham's **Federated Wiki** (Smallest Federated Wiki / SFW,
2011 →) as a **federation model** rather than a single shard: fork-with-provenance,
the per-page **JSON journal** of semantic actions, the **story** of typed items, the
**neighborhood/roster** discovery model, and time-bounded **happenings**.

This is prior art for shard-wiki's **coordination layer itself** — the closest existing
system to "a union of pages preserving provenance, assembled non-destructively." It
extends `research/260608-federation-concepts/` §3 with the concrete data model + protocol.

- `findings.md` — full writeup: data model, journal/action types, federation protocol,
  capability profile, INTENT mapping, UC seeds (UC-70–UC-72), architecture notes for
  SHARD-WP-0002, open questions, sources, traceability.

Catalog yield: UC-70 (attach a fedwiki site via page-JSON + CORS), UC-71 (append-only
semantic action journal with site provenance as a coordination-journal model), UC-72
(fork-with-site-provenance federation across a neighborhood / chorus). Enriched
UC-26/28/30/05/27. Feeds SHARD-WP-0002 T1–T5 (federation) and T11/T13/T16 (write
granularity, log-based merge, identity≠placement).
