ADR 0006 — Wiki Mode (Multi-Editor via Visible Revisions)

Date: 2025-08-22 Status: Accepted

Context

Clone-on-edit bug revealed a path to collaborative editing. We want to formalize this as Wiki mode.

Decision

• Add per-blog wikiEnabled toggle.
• Add Name-based whitelist/blacklist with precedence: blacklist > whitelist > global.
• Posts remain immutable; revisions link via originPostId/parentPostId/lineageBlogId.
• Canonical revision chosen client-side by resolver.

Consequences

• Multiple editors may contribute visible revisions.
• Owner can revoke visibility instantly by changing lists.
• Legacy posts unaffected (wikiEnabled missing = false).

Alternatives

• Server-side canonical logic (not possible in Qortal).
• Per-revision ACLs (heavier; unnecessary for v1).
