Core-1 Diagnostics

Status: normative preview

Core-1 inherits the Core-0 structured diagnostic envelope and adds these fixed meanings:

Code	Meaning
ZL-EDITION-0001	stable Core-1 was selected without an active cumulative preview
ZL-PREVIEW-0001	a declaration or artifact needs a later cumulative preview
ZL-DOMAIN-0002	legacy workflow spelling used where Core-1 requires flow
ZL-DOMAIN-0003	a callable was submitted without its required typed runtime admission or live authority
ZL-DOMAIN-0004	a direct call crosses domains without a typed boundary
ZL-EFFECT-0001	an effect set is missing, malformed, unknown, duplicated, or noncanonical
ZL-EFFECT-0002	a caller does not contain every callee effect
ZL-PORTABLE-0001	a portable set is empty, duplicated, invalid, or used with open/override semantics
ZL-MODALITY-0001	a Core-1 message omitted its required interpreted or compiled modality
ZL-MODALITY-0002	native/JIT/AOT admission reached an interpreted message in the dependency closure
ZL-MODULE-0003	malformed, noncanonical, tampered, or unsupported ZLM2 artifact
ZL-STATE-0001	an unknown or unsupported closed state intrinsic was used
ZL-FLOW-0001	a durable flow definition has an unsupported shape or invalid node/schema/retry/deduplication facts
ZL-FLOW-0002	a source flow boundary or restored history does not match its checked definition
ZL-OPTIMIZE-0001	a finite optimization definition has an unsupported shape, signal signature, identity, or budget
ZL-OPTIMIZE-0002	a source optimizer boundary does not match its checked problem definition

ZL-DOMAIN-0001 retains only its Core-0 deferred-domain meaning. It is not reassigned by Core-1.
