+fix(cli): `os migrate apply` on an empty database writes the organization-ownership birth marker, so the fresh install's first `os serve` starts
+
+Clause-②: yes
+
+`os serve` (and so `os dev` and `os start`) serves a database this release created itself, recognised by the birth marker in `sys_migration` (row `adr-0131-organization-ownership`), or one the ownership ceremony certified. `os migrate apply` holds its schema DDL back until the operator confirms, so its boot saw no table created and wrote no marker, and the tables it then created carried none. A deploy script that ran `os migrate apply` before the first `os serve` was refused as a database "17.x or an 18.0 pre-release created", and sent through the upgrade ceremony.
+
+- **Now.** When `os migrate apply` creates the database from empty, it writes the birth marker right after it creates the tables, and the first `os serve` starts. The log line is the one a serving boot prints: `[organization-ownership] a datastore created from empty: birth marker written (shape generation 1, …)`.
+- **Never on a database that was not empty.** The decision is the serving boot's own: the database counts as created from empty only when none of the tables this release declares existed before the apply. A database an earlier release created gains no marker from `os migrate apply`, even when the apply creates a table in it, and is still refused until the ceremony runs: `os migrate organization-ownership --out PLAN`, then `--apply --plan-file PLAN --backup-taken`.
+- **A failed write fails the command.** If the tables are created and the marker cannot be written, `os migrate apply` exits `1` and names the ceremony, which certifies such a database.
+- **Unchanged.** A database that already carries a marker keeps it as it is. `os migrate plan` writes nothing. On a Turso remote (`libsql://`) primary, `os migrate apply` creates no tables (its schema sync is skipped there), so the first serving boot creates them and writes the marker, as before.

+/**
+ * [ADR-0131 D10; ruling record 6269955919, ① A] `os migrate apply` is the
+ * boot that creates a fresh install's tables when an operator's deploy script
+ * runs it before the first `os serve`, so it writes the organization-ownership
+ * BIRTH MARKER — and only on a database it created from empty.
+ *
+ * Its boot defers schema DDL: each object is stored and skipped before the
+ * driver counts it, so the birth plugin its boot composes sees nothing created
+ * and writes nothing. The tables are created at the confirmed flush, and the
+ * birth half runs there (`SchemaStack.flushSchemaDdl`). The served boot's guard
+ * then judges the file as `os serve` does — read here through
+ * `assertOrganizationOwnershipMigrated` on a boot that creates nothing, so the
+ * verdict is the marker's alone:
+ *
+ *  (a) an empty file: the apply writes one verified birth row, and the guard
+ *      admits the database;
+ *  (b) a database the apply did not create — no marker, the shape an 18.0
+ *      pre-release leaves, and a 17.x one with a retired organization column —
+ *      gets NO birth marker, though the flush creates a table in it and creates
+ *      nothing else, and the guard still refuses it, naming the ceremony;
+ *  (c, d) the apply run again over the database it created and marked, with a
+ *      table to create: one row, unchanged.
+ *
+ * Case (b) is the rule that must not break: a false birth would let a database
+ * an earlier release created skip the ownership ceremony.
