render.yaml

# Render blueprint for the Consensus Slack agent (FREE tier).
#
# The agent talks to Slack via Socket Mode (outbound WebSocket), but Render's
# free tier only offers Web Services, which must bind $PORT and are put to
# sleep after ~15 min without inbound traffic. The start script therefore also
# runs a tiny HTTP health server on $PORT (/healthz -> 200 "ok"); an external
# pinger (cron-job.org or UptimeRobot, every ~10 min) keeps the instance awake.
#
# The free tier has NO persistent disk, so the durable ledger lives in MongoDB
# Atlas (free M0): set MONGODB_URI (connection string) and MONGODB_DB. Data
# persists natively across restarts — no snapshotting. On boot the ledger is
# seeded from seed/seed-decisions.json only when the database is still empty.
# CONSENSUS_DB_PATH is retained solely as the local SQLite/JSON fallback for
# hosts/dev runs where MONGODB_URI is unset; it is no longer the durable store.
#
# First deploy: create from this blueprint, then enter the `sync: false`
# secrets in the Render dashboard. See RENDER-MIGRATION.md for the runbook.
