# Bounded loop for chat: run mail retrieval N times, 1 minute between each.
# Use from Cursor chat when asked to "lance la boucle récupération emails puis attend 1 min et relance".
# Runs in foreground (no background); chat can run it for a few iterations to avoid timeout.
#
# Usage:
#   ./gitea-issues/agent-loop-chat-iterations.sh [N] [--repeat]
#   N = number of iterations (default 3). Each iteration: mail-list-unread.sh then sleep 60.
#   --repeat = after N iterations, relaunch (infinite loop of N-by-N runs).
# Output and mail list (expéditeur, sujet) are appended to projects/<id>/logs/gitea-issues/agent-loop-chat-iterations.log.
