BottleSpec.manifest was ManifestIndex | Manifest — a union encoding two lifecycle stages in one field. The union was unjustifiable: it forced a type-narrowing workaround (loaded_manifest property) on every consumer. Clean split: - BottleSpec.manifest: ManifestIndex (always; CLI-supplied intent) - BottlePlan.manifest: Manifest (always; loaded by _validate()) _validate() returns the loaded Manifest directly. prepare() passes it to _resolve_plan(), which stores it on the plan. All provisioner code now reads plan.manifest.agent / plan.manifest.bottle — no union, no asserts, no type: ignore.
