260614 — git-forge wikis deep dive (Gitea · GitLab · GitHub)

Deep dive on the git-forge-hosted Markdown wikis as one grouped memo: each is a dedicated git repository of Markdown exposed through a forge, attachable by cloning the wiki repo directly or (where offered) through the forge's wiki API. INTENT names Gitea wikis explicitly as a shard participant — this dive confirms the git-native file-store as a first-class, and the simplest, backend.

findings.md — the three forges compared, the .wiki.git model, API matrix, capability profile, INTENT mapping, UC seeds (UC-76/77), architecture notes for SHARD-WP-0002, open questions (resolves the UC-68 source-of-truth question for this case), sources, traceability.

Catalog yield: UC-76 (attach a forge wiki by cloning its dedicated .wiki.git — git is the native store and the coordination journal), UC-77 (attach/write via the forge wiki API where git-clone is unavailable/undesired — capability varies by forge). Enriched UC-40/02/68/38. Feeds SHARD-WP-0002 T14 (attachment binding).
