+fix(cli): the os validate / os build flow-region check never passes a flow it could not judge, and the boot banner counts flows refused at registration
+
+Clause-②: no
+Metadata-protocol: none
+
+- **No silent pass.** The flow-region check `os validate` and `os build` run (the automation engine's registration verdict, ADR-0031) parses each flow with `FlowSchema` before it judges the regions. When that parse failed it used to skip the flow with no row, so the flow passed unjudged. It now refuses it with a `VALIDATION_ERROR` row at the flow's `path`, naming the flow and the schema's issues. No authored stack reaches this branch today: the stack schema has already parsed every flow the check reads, and `FlowSchema` accepts its own output. Nothing refused or accepted today changes.
+- **Refused flows in the boot banner.** When the automation engine refuses a declared flow at registration, boot still continues and the per-flow reason is still under Boot diagnostics. The `os serve` / `os dev` banner now also prints one line beside the declared count, for example `⚠ Flows:   2 flow(s) declared, 1 refused at registration`, read from the engine's own record (`getFlowRegistration`). It prints even when every declared flow was refused and nothing registered. A boot with nothing refused prints no such line.

+// [#29059] The boot banner counts declared flows the engine REFUSED at
+// registration, beside the declared count.
+//
+// A flow `registerFlow` refuses is logged once at WARN and the boot goes on
+// without it (#28893's second ask; that is unchanged here). Before this the
+// banner's Flows line counted only what armed, so a refused flow showed only
+// as a per-flow line under Boot diagnostics, and a boot whose every declared
+// flow was refused printed no Flows line at all.
+//
+// The count is read off the engine's own record: the host's sync calls
+// `recordFlowRefusal` when `registerFlow` throws, and the banner asks
+// `getFlowRegistration(name)` for each declared name, the read the metadata
+// door already serves. So the engine here is the REAL one (dist, already in
+// `KNOWN_UNALIASED_TEST_IMPORTS['@objectstack/cli']`), refusing a real
+// malformed region, not a fake that answers `refused` by fiat. Locally: build
+// `@objectstack/service-automation` before running this.
