Official account export zip or conversations.json
Message counts and timestamps are derived from export data; token values may be unavailable.
Raw prompts, responses, attachments, local paths, and source files stay local in stats-only mode.
Provider export formats may change. Unknown fields are preserved as warnings instead of silently invented metrics.
Re-imports use source IDs, timestamps, file fingerprints, and adapter versions to avoid duplicate totals.
Unavailable values remain null. Estimates are labelled estimated and exact values are never fabricated.
If detection fails, use the preview warnings and confirm the export source/version before importing again.
