replay

Overview ¶

Command replay is the ADR-0019 S1 data-migration CLI: it replays a tq fact journal — the hand-rolled store's database — into a fresh go-cqrs-lite engine store and verifies projection equality. The logic lives in the importable sibling package internal/queue/sqlitev4/migration (shared with the on-open auto-upgrade); this main only owns flags and exit codes.

Usage:

go run ./replay --from <old.db> --to <new.db> [--verify-only]

Exit 0 on a green report, 1 on any projection mismatch, 2 on setup errors. The tool never writes to the source database.
