Diagnostics

Culsma diagnostics are stage-owned.

Family	Stage	Typical cause
LOAD_*	source loading	missing source, duplicate protocol, unknown entry
SEM_*	semantic validation	unknown operation, missing arg, invalid content kind
TYPE_*	type/unit checking	unknown unit, dimension mismatch
PLAN_*	plan lowering	unknown protocol reference, call argument issue
RT_*	runtime	driver failure, scheduler/material orchestration issue
MAT_*	material compute	insufficient material, overflow, conservation failure

The main diagnostic guide describes emitted diagnostics. Roadmap-only diagnostic codes are kept out of this page.

Diagnostics carry severity. error diagnostics block the current stage or run. warning diagnostics record compatibility or fallback behavior without making the result fail.

Current warning examples:

Code	Meaning
SEM_CONTENT_TAXONOMY_COMPAT_NORMALIZED	Older or non-canonical content taxonomy was normalized to a supported kind/type.
MAT_CONTENT_PARTITION_FALLBACK	Runtime material partitioning used the conservative 0.50 / 0.50 fallback.
