+# Identity Resolution Playbook Skill
+
+## When to Use
+- Normalizing provider outputs before syncing to CRM/CDP.
+- Tying intent, enrichment, and product telemetry to the same account/contact IDs.
+- Diagnosing duplicate or conflicting records in downstream systems.
+
+## Framework
+1. **Key Hierarchy** – define primary/secondary keys (domain, account_id, email, person_id).
+2. **Matching Logic** – configure deterministic and fuzzy rules, tie-breakers, and confidence scoring.
+3. **Conflict Handling** – specify precedence rules, merge policies, and exception queues.
+4. **Governance** – document owners, change control, and monitoring cadence.
+5. **Audit Trail** – capture lineage metadata, before/after snapshots, and rollback steps.
+
+## Templates
+- Matching rule matrix (field, rule type, weight, confidence threshold).
+- Exception queue workflow with owners + SLAs.
+- Audit workbook for sampling matches vs source-of-truth.
+
+## Tips
+- Start with deterministic keys (domain, CRM ID) before fuzzy logic to reduce noise.
+- Version rules so downstream teams know when behavior changes.
+- Pair with `signal-taxonomy` to keep IDs aligned with schema updates.
