Q-Blog v0.2.0 — Wiki Mode Canonical Selection

Date: 2025-08-22

Highlights

• Wiki Mode canonical selection: When multiple authors publish the same BLOG_POST identifier, the app now selects a single canonical revision to display based on blog settings.
• Per-blog settings cache: Efficiently resolves each blog’s owner and wiki settings (wikiEnabled, editorWhitelist, editorBlacklist).
• Favorites and Subscriptions respect wiki mode: Lists deduplicate by identifier across names and pick the canonical author.
• Individual post view resolves canonical author when wiki is enabled before fetching content JSON.
• UI: Navbar search/filter and persistent Tile/List view toggle. Notifications consolidated in one place.
• Quality: Accessibility tests and stronger utility/unit coverage; minor code cleanup and worker URL fix.

Canonical selection rules

• Owner is always allowed (cannot be blocked by blacklist).
• Blacklist disallows others even if whitelisted; whitelist gates non-owners if non-empty.
• Among authorized authors: pick latest by updatedAt/qdnUpdated; owner wins ties; otherwise lowest id as last tiebreaker.

Implementation notes

• utils/wiki.ts implements isAuthorized, canEdit, and selectCanonical.
• utils/wikiSettingsCache.ts caches per-blog owner/settings, preferring metadata when available.
• hooks/useFetchPosts.tsx canonicalizes search results for feed, favorites, and subscriptions.
• pages/BlogIndividualPost/BlogIndividualPost.tsx selects the canonical author for the requested post.

Breaking changes

• None. Existing identifiers and endpoints are unchanged.

Fixes & cleanup

• Removed an unused web worker and fixed a BLOG_POST worker URL.
• Removed redundant local helper where a shared util exists.

Upgrade notes

• No migration steps required. Deploy as usual; v0.2.0 is compatible with prior data.
