# invent-topics.sh — topic invention job (replaces in-cycle EXPLORE_INVENT).
#
# Picks ONE project via pick_projects() (same inverse-recent-share weighting
# the post-comments cycle uses), then runs queue-routed Claude turns to
# propose new search_topic candidates given that project's ledger. Validates
# each proposal against the universe (exact-match + Jaccard similarity),
# commits survivors to project_search_topics with source='invented',
# status='active', and POSTs an audit row to /api/v1/invented-topics-audit.
#
# Queue-native (2026-07-06): invoked by the run-draft-and-publish.sh kicker
# on EVERY install (state-file gate, S4L_INVENT_EVERY_HOURS), operator Mac
# included. Every Claude turn is a job on the local claude-queue drained by
# the Desktop scheduled-task worker; there is no claude CLI dependency. The
# operator-only launchd job com.m13v.social-invent-topics is retired.
