# Pruebas de SOLO LECTURA contra la instancia real de Jira (FAC) — Bloques 2,
# 3 (inventario), 4 y 5 de Investigacion-API-Jira.md. Ninguna llamada muta nada.
#
# Requisitos: el token en propuesta/token-jira.txt (gitignoreado) o en $JIRA_TOKEN.
# Uso:  ./pruebas-jira-lectura.sh [directorio_salida]
# La salida VA FUERA DEL REPO por default (los tickets traen datos reales de
# clientes): /tmp/jira-probes-<fecha>. Al repo solo se llevan los hallazgos
# agregados, transcritos a mano a Investigacion-API-Jira.md.
