Every other vector is kernel_generated (a regression vector pinning the kernel's own behaviour, never citable as conformance evidence per AUTHORING-STANDARD.md Sec. 1.5). Coverage: complete lineage resolving to CLOSE_READY, an accrual with no traces_to (unlinked), a traces_to naming a key no coding entry declares (dangling), a lineage key claimed twice (duplicate), the two advisory observations that never gate the verdict (missing source digest, orphan coding entry), a partially-resolving accrual that is dangling rather than linked, and the indeterminate branch on an empty register plus every malformed intake shape (non-array entry lists, missing key, blank key, missing gl_account, non-finite amount, non-array traces_to, blank traces_to entry, malformed as_of). On the indeterminate branch the payload carries an eighth member, errors (non-empty exactly when the one conditional compliance flag CLOSE_LINEAGE_INDETERMINATE is present, per the flag-mirror doctrine); on every assertable input the payload is exactly the seven pinned members and compliance_flags is empty. human_sign_off: PENDING.", "vectors": [ { "name": "worked-example-spec-pinned", "note": "ORACLE vector: the policy_parameters and output_payload below are the spec's own, not the kernel's.
