feat(migrate): add lifecycle commands and standalone authoring

-Create SQL migration files with Goose's
-[`create` command](https://pressly.github.io/goose/documentation/cli-commands/#create).
-For timestamp-to-sequential reconciliation before deployment, use its
-[`fix` command](https://pressly.github.io/goose/documentation/cli-commands/#fix)
-as described in [hybrid versioning](https://github.com/pressly/goose#hybrid-versioning).
-These commands edit source files before embedding; `fix` does not update database
-history. Never renumber migrations already applied to shared databases.
+Use the standalone `corestack-goose` development tool for SQL and Go creation
+and timestamp-to-sequential reconciliation. Its generated Go migrations work
+unchanged with this package's provider-local registration:
 
-**Goose's default Go template is not compatible unchanged with this package.**
-It registers migrations globally from `init`, while this package uses explicit
-provider-local registration. Until the compatible authoring CLI planned in
-[#9](https://gitea.auvem.com/corestack/go/issues/9) is available, Go migrations
-require the adaptation described below; do not treat stock `goose create ... go`
-output as ready to use. That follow-up must supply and document the supported
-creation/reconciliation workflow before it is complete.
+```sh
+go install go.auvem.com/corestack/cmd/corestack-goose@<release>
+mkdir -p migrations
+corestack-goose create --dir ./migrations create_events sql
+corestack-goose fix --dir ./migrations
+corestack-goose create --dir ./migrations populate_events go
+corestack-goose fix --dir ./migrations
+# Or use the version selected by your consumer module:
+go run go.auvem.com/corestack/cmd/corestack-goose create --dir ./migrations add_index sql
+```
+
+The directory must exist and contain regular migration files, with no symlink
+components in its path (on macOS use `/private/tmp`, rather than `/tmp`). Names
+are lowercase ASCII words separated by underscores. Creation uses Goose's stock
+SQL template and a custom transactional Go template. Go files use the fixed
+`<version>_<name>_migration.go` suffix, so names such as `test`, `create_test` and
+`windows` stay buildable on every platform. Edit the SQL or Go up/down function bodies;
+leave factories and the generated `register.go` aggregate intact.
+`GoMigrations()` supplies fresh registrations on each call. The aggregate exists
+even for SQL-only sets. Versions are unique across SQL and Go; Goose timestamps
+have second resolution, so fix a new migration before creating another in the
+same second, or wait for a distinct timestamp.
+
+`fix` preserves sequential IDs, allocates timestamps after the highest sequential
+ID with at least five-digit padding, and updates filenames and registration
+literals together. It preserves migration bodies. It rejects unsupported Go
+layouts, edited aggregates, duplicate versions/factories, unsafe paths, collisions,
+overflow and lexical/numeric order disagreement before writing. It does not adapt
+stock Goose Go output, whose global `init` registry is incompatible here.
+For concepts, see Goose's [hybrid versioning](https://github.com/pressly/goose#hybrid-versioning)
+and [SQL annotations](https://pressly.github.io/goose/documentation/annotations/).
+
+Before `fix`, commit or separately back up the **complete source set**, including
+untracked migrations and tracked edits. Run one authoring process with no concurrent
+editor changes. New destinations are exclusive; the tool stages output and fully
+publishes each destination before removing its old source. This is **not an atomic
+multi-file operation**. On a write/removal failure, stop and inspect the reported
+completed, partial/current and outstanding paths. Restore the complete source set
+and aggregate from that commit/backup before retrying; ordinary Git restore cannot
+recover untracked files or unsaved edits. Interruption can leave duplicates,
+aggregate drift or staging files; there is no automatic rollback or journal.
+
+Source reconciliation never rewrites database history. Use it before those IDs
+reach a shared database; preserve deployed IDs and add migrations afterward. The
+tool cannot determine deployment history.
+
+The standalone tool has no database setup. Production imports `migrate` and,
+optionally, `migrate/lifecycle`; neither imports authoring code. No build tags are
+needed. The generated consumer imports only Goose and the standard library.
+The artifact test builds both executables, decodes production dependency identities,
+and checks linker symbols for project authoring and Goose Create/CreateWithTemplate/
+Fix/SetSequential entrypoints. Goose's package remains a runtime dependency;
+these checks establish the tested build's boundary, not a universal ban on file I/O
+or proof about arbitrary downstream binaries. Build your application normally.

-registration versions to match. Versions must be unique across SQL and Go files.
+For generated Go functions, import the consumer's migration package and pass
+`migrations.GoMigrations()...` as the trailing arguments to `migrate.New`.
+Embed the complete directory with `//go:embed migrations` (and use a different
+variable name, such as `migrationFiles`, from the imported package). The directory
+must exist even for Go-only sets. Global registration is disabled; never share
+mutable registration objects across providers. See Goose's

+
+## Lifecycle startup and native commands
+
+`go.auvem.com/corestack/migrate/lifecycle` is a thin adapter; `migrate` itself has
+no lifecycle dependency. Alias it `migratelifecycle` to distinguish the core
+lifecycle package. Its resolver runs after the caller's database setup and should
+construct a fresh provider with fresh registrations:
+
+```go
+resolve := func(ctx context.Context) (*goose.Provider, error) {
+    return migrate.New(db, goose.DialectPostgres, migrationFiles,
+        "migrations", logger, migrations.GoMigrations()...)
+}
+startup, err := migratelifecycle.Module("migrations", migratelifecycle.Require, resolve)
+if err != nil {
+    return err
+}
+root := &urfavecli.Command{Name: "app", Commands: []*urfavecli.Command{
+    {Name: "serve", Action: cli.Serve(cfg, []lifecycle.Module{database, startup, server})},
+    migratelifecycle.Commands(cfg, []lifecycle.Module{database}, resolve),
+}}
+code, err := cli.Run(ctx, root, args) // args includes argv[0]; caller owns process exit.
+```
+
+Here `database.Setup` opens `db` and cleans up its partial acquisition on failure;
+`database.Teardown` closes it. Construct the tree and captured resource bindings
+fresh for independent invocations. Declaration does no work. Select `Apply` to run
+Up during setup, or `Require` to fail before later setup/services when migrations
+are pending. Require is a point-in-time check without a deployment lock. It and
+status may initialize Goose's version table; neither promises read-only DB access.
+The migration module never closes the provider or shared database.
+
+The native group supplies `migrate up`, `up-to <version>` (inclusive), `down`
+(one migration), `down-to <version>` and `status` (version/state/source table).
+Pass exactly the database modules, excluding the startup migration module and
+unrelated modules. Services are suppressed; the existing `lifecycle/cli.Action`
+owns signals, cancellation, errors and reverse cleanup. Help and invalid arguments
+never run setup. Target versions must be nonnegative decimal int64 values, with
+no extra arguments; malformed usage returns exit 2 through `cli.Run`. Zero follows
+Goose: `down-to 0` rolls everything back, while `up-to 0` is a runtime error.
+Resolver/Goose/cleanup and status Writer failures return runtime errors (exit 1).
+Supply the native command Writer and configured Goose logger for output.
 
 Postgres providers automatically use Goose's default session advisory locker.
 Concurrent startup calls from separate providers/processes serialize migration
