## 1. Define account scope and field sources

Read four synthetic biographies. List original row id, account_id, visible fields and allowed source. Use uploaded material only; do not search accounts/sites or contact anyone.

Expected: A four-row source index.
Check: Original rows and stable identities are distinct.

## 2. Extract facts and leave unknowns blank

Extract handle, biography, public city and website exactly, with P ids per field. Keep unpublished cities null. Infer no income, occupation or contact details; do not call example.com a verified homepage.

Expected: A traceable fact table.
Check: Only u102 has a supplied public city.

## 3. Assign field tags only from explicit text

Tag u101 independent development and u102 product design with quotations. Mark u103 unconfirmed. Do not force a vague bio into investing or AI. Save tag-map.csv.

Expected: Three evidence-based tag states.
Check: u103 receives no invented field or occupation.

## 4. Deduplicate without losing original mapping

Merge P01/P03 by account_id. Return3 profiles plus the mapping from 4 original rows. Send conflicting fields to review without silent overwrite. Produce an import file; do not write Notion.

Expected: Three profiles and source mapping.
Check: All four inputs are accounted for; u101 appears once in final records.

## 5. Compare existing identities before a live import

Read <target data source> schema and account_id keys. Preview proposed inserts/updates. After confirmation, write only those items and read back page ids. Check duplicates after unclear failures. If tools are missing, return CSV; do not search private data or send messages.

Expected: A verified import or local handoff.
Check: Reruns do not create duplicate people or overwrite manual fields.

## 6. Date updates and retain removal handling

Draft a public-profile-index Skill with account list, limit, field evidence, blanks, identity deduplication, conflicts and observation times. Default to a diff for review. Do not enrich private fields, bulk update or contact profiles automatically.

Expected: A maintainable update method.
Check: Old/new sources and dates remain traceable.
