# Wiki Mode / Multi-Editor — Product Overview

_Generated 2025-08-22_

## Summary

Q-Blog gains a new **Wiki mode**, allowing multiple **Names** to publish **visible revisions** of posts under a blog.

- **Names** are the identity key (not account addresses).
- Authorization is computed **client-side**; Qortal has no server scripting.
- Precedence: **blacklist > whitelist > global allow**.
- Backward-compatible: missing fields mean wiki is off.

## UX

> Editors **do not need their own blog** to publish a revision on a wiki-enabled blog.

- **Blog Settings:** toggle Wiki Mode; configure whitelist/blacklist of Names.
- **Post page:** shows the canonical (latest visible) revision with author/date attribution.
  - Implemented: canonical chosen across Names by exact BLOG_POST identifier; attribution shown when author differs from owner.
- **Edit button:** shown only to Owner and authorized editors.
- **Blog list:** groups posts by lineage and shows canonical revision per group.
  - Implemented for Blog page (`/{name}/{blog}`) using identifier-grouping.
  - Global feed, Subscriptions, and Favorites canonicalize duplicates via a cached lookup of per-blog wiki settings.
  - Header “My Blogs” switcher updates both title and posts by seeding blog context immediately.

## Canonical Selection (v0.2.0)

The app selects one canonical revision when multiple Names publish the same `BLOG_POST` identifier:

- Authorization first: filter out unauthorized Names using blog settings. The Owner is always allowed (cannot be blocked).
- Freshest wins: compare `updatedAt` or `qdnUpdated`; pick the most recent.
- Tie-breakers: if timestamps tie, prefer the Owner; otherwise, pick the lowest id for stability.

This logic is applied consistently in:

- Main feed pages and “Load new posts”.
- Favorites and Subscriptions lists.
- Individual post view before fetching content.
