# Fetch the full issue thread (shared memory) into /tmp/thread.md.
# Agents post as their OWN Gitea users, so .user.login IS the agent name — attribute each comment
# to its real author (@pm/@qa/@junior/…). Strip the hidden `<!-- 🤖 … -->` loop-prevention marker
# from bodies — it's plumbing, not conversation, and would just waste prompt tokens.
#
# PAGINATION: Gitea returns comments ASCENDING and `limit` caps a single page — a bare ?limit=100
# used to keep the OLDEST 100 comments and silently drop the newest (the exact opposite of what an
# agent needs on a long thread). Fetch all pages (up to 10 = 500 comments) and keep the LAST 100.
#
# Required env (provided by the workflow step): GT NUM GITHUB_SERVER_URL GITHUB_REPOSITORY
