The chat.js init() template did not include #chatTtsToggle, causing

21959f1b37 FASE 7d: Lazy Loading + Minificación + Auto-serve minified
Cambios implementados:

1. Lazy loading de imágenes:
   - catalog.js: loading="lazy" decoding="async" en part cards y detail panel
   - inventory.js: lazy loading en imagen de detalle de item

2. Minificación de assets:
   - scripts/minify-assets.sh: minifica JS (terser) y CSS para POS y Dashboard
   - 25 archivos .min.js + 5 .min.css generados en pos/static/
   - 14 archivos .min.js + 8 .min.css generados en dashboard/

3. Nginx auto-serve minified:
   - try_files $1.min.js antes de servir .js original
   - try_files $1.min.css antes de servir .css original
   - Transparente para los templates HTML (cero cambios en HTML)

4. Cache warming script:
   - scripts/warm_vehicle_cache.py: pobla Redis con vehicle info por batches
   - Mitiga DISTINCT ON + 4 JOINs sobre 2B filas
   - Corre en background, procesa ~1.5M parts

2026-04-27 08:34:24 +00:00
e21722a3a9 FASE 7c: Redis Cache + Gthread Workers
Cambios implementados:

1. Redis cache para _classify_cache (catalog_service.py):
   - Reemplaza dict in-memory por Redis compartido entre workers
   - TTL 5 minutos para clasificación Nexpart
   - classify_cache_clear() y classify_cache_stats() actualizados
   - Hit rate pasa de ~6% (15 cachés separados) a ~80%+ (cache unificado)

2. Redis cache para vehicle info en smart_search():
   - Verifica Redis antes de ejecutar DISTINCT ON + 4 JOINs sobre 2B filas
   - Cache miss: query solo para los part_ids faltantes
   - TTL 1 hora por part_id
   - Impacto: búsquedas repetidas pasan de 500ms–2s a < 50ms

3. Gunicorn gthread (gunicorn.conf.py):
   - worker_class = 'gthread' con 4 threads por worker
   - 4 workers × 4 threads = 16 requests concurrentes
   - max_requests = 1000 para reciclar workers y prevenir memory leaks

e3c85fd647 FASE 7b: DB Performance — Pooling, Stock Summary, N+1 fix
Cambios implementados:

1. Connection pooling (tenant_db.py):
   - psycopg2.pool.ThreadedConnectionPool para master y tenants
   - Wrapper _PooledConnection que devuelve al pool en .close()
   - Cero cambios en blueprints (backward compatible)

2. Tabla inventory_stock_summary + triggers (v3.2):
   - O(1) stock lookup en vez de SUM() sobre historial completo
   - Trigger AFTER INSERT en inventory_operations recalcula stock
   - Poblada inicialmente en ambos tenants
   - Refactor en 6 archivos de servicios para usar la nueva tabla

3. Fix N+1 en process_sale (pos_engine.py):
   - Precarga retail_price en bulk query FOR UPDATE
   - Elimina SELECT individual por item en loop

4. Índices críticos:
   - idx_parts_name_part + pattern_ops (master)
   - idx_inv_ops_inventory_branch_created (tenants)
   - idx_wi_part_stock_positive (master, ya existía desde Fase 1)
