# Proof of Work (proof-of-work) — StartOS 0.4 container entrypoint.
#
# Responsibilities (in order):
#   1. Ensure the persistent /data directory exists.
#   2. Seed /data on truly-fresh first boot:
#      a. If /app/seed/data/app.db is present (v1.0.0:1 cutover image),
#         copy it into /data. This is how an operator migrating from
#         the legacy `workout-log` package preserves their full history.
#      b. Otherwise fall back to the empty-schema fallback DB at
#         /app/prisma/data/app.db (already seeded with the curated
#         exercise library at build time).
#      Both branches are gated on /data/app.db being absent AND
#      /data/.seeded being absent — never overwrites live data.
#   3. Run idempotent compat ALTERs for columns added after older snapshots.
#      No-ops on hosts whose schema is already current.
#   4. Ensure the curated exercise library is present for every user. New
#      maintainer-shipped exercises appear on every boot (INSERT OR IGNORE
#      keyed on (userId, name); never overwrites a user's own exercises).
#   5. Exec the Next.js standalone server as PID 1 (under dumb-init).
#
# Every branch logs to stderr so it is visible in StartOS -> Logs.
