Promotion prep for the contract-apply cutover, which unlike the quick-sell
promotion moves BOTH binaries and applies a schema migration.
fifa17-promotion-backup.py uses SQLite's online backup API, not cp. Production
runs WAL with a routinely uncheckpointed WAL (515 KB at capture time); copying
the main file alone is not atomic against a live writer and carries no
guarantee the WAL holds no newer committed state. Emits a checksummed backup, a
metadata record and a RESTORE-*.sh that removes the stale -wal/-shm BEFORE
restoring -- omit that and SQLite replays the old journal over the file you just
put back, resurrecting the state you were abandoning.
fifa17-promotion-snapshot.py is read-only (mode=ro) and counts EVERY table
rather than a hand-picked list, so a delta cannot hide in a table nobody thought
to name. It also fingerprints the ownership rows, catching a row silently
rewritten when counts alone would match.
fifa17-contract-apply-validate.py gains --host/--db so one tool serves staging,
the migration rehearsal and the production acceptance run. Defaults stay
staging: there is deliberately no production default, so a bare invocation
cannot touch production.
