# 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).
