SHARD-WP-0003 T1. Federation model (not a shard candidate): per-page append-only semantic-action journal with story as derived replay, fork-with-site-provenance, neighborhood/roster discovery + chorus of forks. Prior art for shard-wiki's own pillars: coordination journal (UC-71), overlay-before-mutation (UC-26 fork), union-without-erasure (UC-72). Attach as REST/file-store hybrid (page JSON + CORS, UC-70). Feeds SHARD-WP-0002 T1-T5, T11, T13, T16. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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).
