podium-contact-dedup

Deduplicate Podium contacts in production and survive the data-quality failures — phone-format inconsistency producing four contacts for one phone, merge-api ordering that silently discards the richer record, opt-out flags lost on merge re-enabling marketing on an opted-out person, soft-delete confusion, cross-location duplicate blind spots, and simultaneous-merge race conditions. Use when you build a Podium dedup pipeline, scan and detect duplicate clusters, normalize phones to e164 form across an entire contact corpus, preserve opt-out state through merges, or validate cross-location duplicate resolution. Trigger with "podium contact dedup", "podium phone normalization", "podium e164", "podium duplicate contacts", "podium merge contacts", "podium opt-out preservation", "podium cross-location dedup".
