1. prescreener.py: classify_with_deepseek now retries on 429 with
exponential back-off (5s → 10s → 20s → 40s, up to 4 attempts);
same back-off also covers other transient errors.
2. main.py: prescreen batches run sequentially with a 3s gap instead
of asyncio.gather (parallel). Parallel batches caused the second
batch to always hit the 429 rate limit, leaving most domains
unclassified (only the smaller last batch succeeded).
3. index.html: prescreenSelected() now clears this.domains before
calling _fetch() so Alpine re-renders the full table with the
updated niche/type values; also updates the notify hint to mention
the expected 1-2 min wait.

Phase 1 (no AI credits): httpx checks every selected domain concurrently
(30 parallel) with real browser UA — detects live/dead/parked/redirect.
Parked: keyword scan in body/title + known parking host redirect check.
Results saved to DB immediately; dead/parked never reach DeepSeek.
Phase 2 (single DeepSeek call): all live-site titles + snippets bundled
into ONE Replicate/DeepSeek-R1 request → returns niche + type for every
domain in batch (up to 80 per call, parallelised if more).
- app/prescreener.py (new): _check_one(), prescreen_domains(),
classify_with_deepseek(), parking signal lists, same-domain redirect logic
- app/db.py: prescreen_status/niche/site_type/prescreen_at columns +
migrations; save_prescreen_results() upsert helper
- app/main.py: POST /api/prescreen/batch endpoint
- app/static/index.html:
- 🔍 Pre-screen button (disabled while running, shows spinner)
- Niche + Type columns in Browse and Leads tables (.pni/.pty pills)
- Prescreen status colour dot (●) when niche not yet set
- prescreening state flag; result toast shows per-status counts

- db.py: add `language` column to ai_queue; migration; queue_ai() accepts
language param and re-queues with ON CONFLICT UPDATE so changing language works
- main.py: batch and single assess endpoints accept `language` from request body
- enricher.py: ai_worker_loop reads language column, passes to _assess_one()
- replicate_ai.py: assess_domain() and _build_prompt() accept language param;
OUTPUT LANGUAGE section injected into prompt so Gemini writes pitch/email in
the requested language (EN/ES/RO)
- index.html: flag dropdown (🇪🇸/🇬🇧/🇷🇴) next to AI Assess button; aiLang
state default ES; language sent in all batch assessment requests

AI worker fixes (root cause of "nothing reaches Replicate"):
- Worker task died silently — no exception handler around while loop
- Added try/except around entire loop body with exc_info logging
- Added watchdog task that restarts dead workers every 10 seconds
- ensure_workers_alive() called on every /api/ai/assess/batch POST
- _assess_one() is now a top-level function (not closure) — avoids
subtle scoping bugs with async inner functions in while loops
- /api/ai/debug endpoint: shows worker alive status, task exception,
last 10 queue entries — browse to /api/ai/debug to diagnose
- /api/ai/worker/restart endpoint + UI button
- "Restart AI worker" button + "Debug AI queue" link in enrichment tab
site_analyzer.py — new signals:
- IP resolution + ip-api.com for ASN, org, ISP, host country
- EU hosting detection (27 EU + EEA + adequacy countries)
- GDPR: detects Cookiebot, OneTrust, CookiePro, Osano, Iubenda,
Borlabs, CookieYes, Complianz, Usercentrics + text signals
- Privacy policy and GDPR text presence
- Accessibility: html lang missing, images without alt count,
skip nav link, empty links, inputs without labels
Gemini prompt additions:
- Hosting section: IP, ASN, org/ISP, EU vs non-EU flag
- GDPR section: cookie tool, notice, privacy policy
- Accessibility section: all quick-scan results
- New output fields: hosting_notes, gdpr_compliance,
accessibility_issues[]

- Build /data/domains.duckdb on first run (tld+parts columns + ART index)
→ TLD filter goes from ~60s full scan to <100ms index lookup
→ System still works (slower) while index builds in background
- New /api/domains params: alpha_only, no_sld, keyword
→ alpha_only: domains with only letters (no hyphens/numbers)
→ no_sld: parts=2, excludes com.es / net.es patterns
→ keyword: LIKE '%term%' niche search
- /api/domains and /api/enriched now return total count for pagination
- Pagination: shows total matches, page X of Y, Next disabled at last page
- Enrich button: toast notifications instead of alert(), error handling
- Select all on page button, clear selection button
- Stats/TLD breakdown cached after first load (no repeat full scan)
- Header shows index build status (building → ready)
