# =============================================================================
# Digest notifications cron (consolidated: digest + brief compose + channel send)
# =============================================================================
# Runs scripts/seed-digest-notifications.mjs as a Railway cron (every 30 min).
# The script now also owns the brief envelope write path — per-user
# brief:{userId}:{issueDate} keys are produced here, and every channel
# dispatch (email/telegram/slack/discord) gets a signed magazine URL CTA.
#
# Historical context: before 2026-04-18 this service built from the
# scripts/ root with plain `npm ci`. The consolidation PR introduced
# cross-directory imports (shared/*, server/_shared/*, api/*) so the
# service now needs repo-root as build context with the specific
# modules COPY'd in. The retired seed-brief-composer Dockerfile had
# the same pattern.
#
# Required env (Railway service vars):
#   UPSTASH_REDIS_REST_URL
#   UPSTASH_REDIS_REST_TOKEN
#   CONVEX_URL                    (or CONVEX_SITE_URL)
#   RELAY_SHARED_SECRET
#   RESEND_API_KEY
#   TELEGRAM_BOT_TOKEN
#   BRIEF_URL_SIGNING_SECRET      (brief compose disabled without this)
#   WORLDMONITOR_PUBLIC_BASE_URL  (defaults to https://worldmonitor.app)
# Optional:
#   DIGEST_CRON_ENABLED=0         (kill switch for the whole cron)
#   BRIEF_COMPOSE_ENABLED=0       (kill switch for just brief compose)
#   AI_DIGEST_ENABLED=0           (kill switch for AI summary LLM call)

# The repo-root package.json has "type":"module" which tells Node to

# this image we don't ship the full root package.json (it would pull
# in dev-deps metadata we don't need), but the .js files we DO ship
# still need the nearest-pjson walk to resolve to an ESM declaration.
