# -*- coding: utf-8 -*- """ BANCO DE PRUEBAS AISLADAS V4 — TEITAN RESCUE ENGINE Valida física y estrictamente las 8 condiciones exigidas por el Creador: 1. TEST_INCREMENTAL_CHECKPOINT_WRITES: SQLite WAL con escrituras O(1) sin crecimiento cuadrático. 2. TEST_RESUME_NO_READ_SOURCE: Reanudación real leyendo únicamente destino, sin leer el archivo de origen C:. 3. TEST_CORRUPT_CHECKPOINT_BLOCK: Base SQLite corrupta bloquea la ejecución de inmediato sin perder estado silenciosamente. 4. TEST_REJECT_TRUNCATED_COPY: Detección y rechazo inmediato de copia truncada (bytes leídos != tamaño inicial o cambio en origen). 5. TEST_NONZERO_EXIT_CODE_ON_FAILURE: Falla de integridad o interrupción propaga exit code != 0. 6. TEST_INACCESSIBLE_DIR_DETECTION: Error explícito y aborto ante directorios no legibles durante exploración. 7. TEST_PRIORITY_DIGITAL_OPTIMUS: Digital Optimus (C:\\xampp\\htdocs\\Digital Optimus) se indexa y procesa primero. 8. TEST_PRESERVE_RECOVERED_AND_ZIPS: Archivos previos en stage y ZIPs históricos se conservan íntegramente.
