High priority fixes:
- T0: Profile page now filters comments by namespace (was leaking cross-site)
- T1: URI hostnames and namespace names normalized to lowercase (was causing
  duplicate threads and "stock comments" bug). Includes merge script.
- T2: Thread detail API now paginated with SQL-side filtering (was 502 on
  267+ reply threads)

Features:
- T3: GDPR account deletion (tombstone user with scrubbed PII) and data export
- T4: Customizable button text and comment labels per namespace
- T5: Self-service namespace deletion for owners
- T6: @mention notifications with profile links
- T7: Webmention receiving endpoint with h-card extraction
- T8: Configurable max nesting depth and collapse depth per namespace
- T9: AJAX thread title search to prevent duplicates
- T10: Browser push notification support (VAPID/service worker)

Docs and housekeeping:
- T11: Documented thread_uri behavior when moving embeds
- T12/T13: Drafted community replies for resolved feature requests
- Collapse depth defaults to infinite (load-more disabled unless configured)

364 tests pass, 4 skipped.

# T9: Prevent duplicate threads (AJAX search)
**Status**: resolved
**Priority**: low
**Source**: meta `642831b4-4cbf-11e9-9d67-040140774501`
**Filed**: 2026-02-01
## Problem
On standalone and FAQ sites, users can create threads with duplicate titles. There's no feedback showing existing threads before creation.
## Proposed Implementation
1. Add an AJAX search endpoint that returns threads matching a title prefix
2. Wire it into the "new thread" form with a debounced typeahead
3. Show matching existing threads as suggestions before submission
## Files
- `remarkbox/api/__init__.py` — added `api-threads-search` route
- `remarkbox/api/views.py` — added `api_search_threads()` endpoint (GET /api/v1/threads/search)
- `remarkbox/static/js/custom.js` — debounced typeahead for thread title input
- `remarkbox/static/css/common.css` — CSS for suggestion dropdown
- `remarkbox/templates/base.j2` — added `data-namespace` attribute to body tag
## Acceptance Criteria
- [x] Typing a thread title shows matching existing threads
- [x] Users can click a suggestion to navigate to the existing thread
- [x] New thread creation still works when no match exists
