Summary#
Bugs in compilers and build systems often appear after intermediate layers discard the original identity, ownership, or placement information and later stages try to reconstruct it indirectly. A better approach is to carry canonical provenance forward on the transformed artifact itself and have diagnostics and executors consume that source of truth. This both improves debuggability and reduces behavior drift during refactors.
Problem#
Derived layers were losing or re-deriving package identity, fusion ownership, or original sharding metadata, which caused ambiguous diagnostics and incorrect downstream behavior when later stages needed the original context.
Solution#
Attach stable provenance metadata to intermediate objects, route downstream logic through that canonical context instead of manifest/path inference, and add tests for legacy or compatibility cases where reconstructed context used to fail.
Failure Modes#
- Recomputing identity from filenames, manifests, or enclosing structure after the fact
- Improving error text without preserving machine-readable provenance
- Migrating consumers before a canonical context object or metadata contract exists
