Limits and unknowns

Only supplied rows and selected fields are checked; extract completeness is not verified.
Unselected fields are excluded, not passed. No other row exclusions are configured.
Exact text includes blanks; two blank fields do not establish valid business data.
Decimal equality does not validate currency, units or business meaning; no totals are assurance.
Relationship identifiers are compared as text, not verified against referenced records.
Attachments, file accessibility and effective user permissions are unknown.
Evidence row numbers are physical CSV line starts; header starts at line 1.
No live CRM, attachment content or effective permissions are checked. Human business review is required.

Reviewer decision

Pending. The delivery owner must verify provenance, rules and findings, resolve excluded or unknown checks with the client, and agree any rerun. No customer acceptance or commercial readiness is implied.
