CRM archaeology is necessary, and it is also a trap. Teams spend quarters deduplicating history, reconciling old portals, and arguing about records a live process will never touch again. Meanwhile every new form, meeting note, and partner upload recreates the same mess. Agents do not wait for the archive to be perfect. They read whatever the portal returns today, including half-filled company names, free-text industry values, and notes that contradict the current stage.
Hallucination in this setting is usually a data problem wearing a model costume. The agent is asked a reasonable question: which accounts are in evaluation, who is the economic buyer, what happened on the last call. The portal answers with unstructured blobs, duplicate contacts, and fields that mean different things by region. The model fills the gaps. It invents a title, merges two people, or treats a stale note as current intent. Cleaning records from years ago will not stop that. The quality of tomorrow's capture will.
Start at the front door. Require structured fields on every new record that an agent, a representative, or a sync will later read. Company domain, country, employee band, buying role, product interest, and source should be controlled values, not essays. Free text belongs in a notes field with a date and an author, not in the columns a workflow branches on. If a form can submit without those fields, the agent will be asked to guess them later. That is the expensive version of data entry.
Do not pause live operations until the historical cleanup finishes. Split the program. One stream remediates the high-value accounts sales will actually work. The other stream changes capture: form validation, integration mappings, required fields on portal objects, and a short reject list for junk values such as test, n/a, and a personal email on an account domain. New records should be safe for an agent even while the warehouse of old ones is still dirty.
Measure the forward path, not just the backfile. Track the share of records created this week that have complete structured fields, a unique domain, and a single primary contact. If that share is low, an agent on the portal will keep sounding confident and being wrong. An AI automation readiness assessment is more useful here than another extraction of the archive, because it asks whether the current system can support a model without improvising.
If you are about to put an agent on CRM or portal data, fix what enters the system tomorrow and contain the archaeology to records that matter.
