Queen coordinator briefing — swarm-2026-07-25-csv-dedupe

Objective: collapse duplicate contacts during the CSV import so that rows sharing
a normalized (email, phone) key are written once, the first-seen row is retained,
and every dropped row is recorded with its source line number.

Coordination notes for the worker agents:
  - Spawn one coder per acceptance criterion; the reviewer re-runs the import.
  - Record each SPARC phase artifact into the sparc-phases memory namespace.
  - Verify all subtasks are complete before reporting the objective as met.

This prompt file is the record of what the swarm was asked to do. It is an input,
not evidence of the outcome — the outcome is decided by the supervising gate.
