Why is a mismatch harder for an agent than a normal lookup task?

**Why is this harder than a lookup?** A lookup has one source and one answer. A mismatch has two sources that disagree, and the answer is a cause plus an action.

**What makes it hard?** - The evidence is spread across systems, so the agent must choose which to query next. - More than one cause can produce the same difference: timing, duplication, a reversal, a rounding rule, a wrong key. - The visible gap may be the sum of several small problems. - The tempting fix, editing a record until the totals match, is often the wrong one.

**Does the agent need to fix everything?** No. Some mismatches belong to another team or need approval. Correctly escalating with a clear note is a valid outcome, and training material should label it as one.

**Why not rely on general agent tasks?** General tasks seldom test whether an agent respects write permissions, tolerances and audit trails while it investigates. A task pack built for this workflow can carry a known root cause and a set of acceptable and unacceptable actions, so you can score the path as well as the result.

**Is the data real?** The output MirrorFirm provides is generated. Buyers should inspect grounding and disclosure risk in a sample.
