Three admin Sources upgrades:
- Deep preview: a per-candidate "🔬 Deep preview" button runs the REAL
classifier on an 8-item sample (the same model that judges live articles),
versus the fast keyword heuristic the add/Re-preview path uses. Preview now
carries `classified`, surfaced as a "model-checked" vs "quick estimate"
badge — so the acceptance % is no longer ambiguously heuristic. conn is
released during the ~30-60s model pass; postJSON has no client timeout.
- Search: free-text box over the sources table (name / category / feed URL /
homepage), folded into the existing status filter, with a live match count
and empty state. Makes "is this already added?" a glance.
- Duplicate-add guard: sources.find_existing_feed() + feed_key() normalize
scheme/www/trailing-slash/case, so re-adding a feed that's already a live
source or a queued candidate is refused with a 409 naming where it lives
(DB already enforced exact-URL uniqueness; this catches the near-miss
variants and overwrite-on-promote footgun).
Tests: test_candidate_deep_preview_and_dedup (deep flag wires the model +
uses the small sample; exact/www/slash/case variants all 409). 224 pytest +
11 vitest green.
