# Proof of Work (proof-of-work) — StartOS 0.4 container entrypoint.
#
# Responsibilities (in order):
#   1. Ensure the persistent /data directory exists.
#   2. First-boot fallback ONLY: if /data is empty (no app.db, no
#      .seeded marker) AND a fallback DB exists at
#      /app/prisma/data/app.db, copy it into /data. This handles
#      brand-new sideloads on a host that has never had proof-of-work
#      installed before. Existing installs ALWAYS skip this branch
#      because /data/app.db is already present.
#      (v1.0.0:1 had a second branch that copied a baked cutover seed
#      from /app/seed/data/app.db. v1.0.0:3 stripped both the COPY of
#      that seed in the Dockerfile and the branch that copied it here,
#      now that the cutover from `workout-log` is verified done.)
#      (v1.0.0:4 made another change to this fallback DB: it now
#      contains ONLY the InstanceSettings singleton, NOT a default
#      admin user or seeded exercises. The operator is required to
#      run the StartOS Action 'Set admin credentials' to bootstrap
#      the first admin — eliminates the default-credentials footgun.)
#   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.
