+fix(cli): `os dev`'s in-place upgrade line no longer says every refused database is "still in the v17 organization-ownership shape"
+
+Clause-②: no (printed text of `os dev` only: no exit code, refusal, recovered boot or IPC message moves)
+
+When the organization-ownership boot guard refuses the server `os dev` starts, `os dev` copies the development database and upgrades it in place. The line it printed first said the database was "still in the v17 organization-ownership shape", for every refusal. That was wrong for a database an 18.0 pre-release created, and for every refusal that is not about the database's origin at all: a marker that is unverified, unreadable or from an older shape generation, or a read or write the guard could not make.
+
+The line now names no origin. It points at the guard's own refusal, printed just above it, which says what the guard found, and it says that `os dev` upgrades the database in place, keeping a copy first. The verdict line printed after the upgrade still gives the copy's path. Which databases `os dev` upgrades, how it upgrades them, and what a bare `os serve` prints are unchanged.

+/**
+ * #24833 — what `os dev` prints when the organization-ownership boot guard
+ * refused its `serve` child and it upgrades the development database in place.
+ *
+ * The coordinator's `recover` in `dev.ts` calls `upgradeRefusedDevelopmentDatabase`
+ * with `console.log` and the real upgrade. Here the upgrade is faked: what it
+ * does is `utils/dev-organization-ownership-upgrade.test.ts`'s subject, and the
+ * line it prints is this file's.
+ *
+ * ## The defect
+ *
+ * The first line used to say the database was "still in the v17
+ * organization-ownership shape" for every refusal. The guard refuses a database
+ * whose marker is absent, unverified, unreadable or from an older shape
+ * generation, or whose shape or birth marker it could not read or write, and
+ * only the absent marker means "17.x or an 18.0 pre-release created it". So the
+ * line names no origin at all: the guard's own refusal, printed just above it
+ * by the failed boot, does.
+ *
+ * ⛔ The sentence is not pinned verbatim. The pins are what it must not say (an
+ * origin) and the things it must name: the refusal above, the in-place
+ * upgrade, the copy. The copy's path is the verdict line's, from the result.
