The deployment manifest

Top-level keys of manifest.json:

Key	Type	Meaning
schema_version	int (1)	Plugin-schema version. Absent ⇒ treated as v1 (backward-lenient). Newer than the loader ⇒ rejected (forward-strict).
version	int (1)	Legacy manifest-version alias (always 1). Retained for pre-freeze readers; a loader falls back to it when schema_version is absent.
pattern	string	Plugin family of the set. The code generator’s Bundle builder emits one of the canonical "vector" | "pure" (a bundle is pattern-homogeneous). It is a schema discriminant: an unknown value is rejected by every loader, Python and C++ alike. Python’s loader is additionally absence-strict (an absent pattern is rejected too — dispatch needs it to pick LoadedVector/LoadedPure); the two C++ registries stay absence-lenient (a pre-freeze manifest that never stamped one still loads — neither registry dispatches a variant class off it). See Compatibility policy.
aether_abi	const "aether-abi/1"	Binary-ABI tag (see The aether_abi tag is separate). Orthogonal to schema_version.
plugins	array	The set’s plugin entries in declared (injection) order.

Each plugins entry:

Key	Type	Meaning
id	string	Stable, unique plugin id (from the kernel function name).
order	int ≥ 0	Injection order == list index.
enabled	bool	Whether the registry loads this plugin.
artifact	string	Artifact filename, relative to the manifest directory.
sidecar	string	Sidecar filename, relative to the manifest directory.
format	"ptx" | "cubin" | "fatbin"	Artifact format: arch-portable PTX, single-arch cubin, or multi-arch fatbin.
