Required Outputs

• voice rule update proposals
• contact-tier update proposals
• allowlist or blocklist additions
• threshold change recommendations
• changelog entry

Safe Auto-Applied Updates

Allowed without approval:

• raise thresholds
• add new protected contacts
• add new blocklist entries for repeated junk
• add unsubscribe candidates
• append retrospective notes and changelog entries

Approval-Required Updates

Never auto-apply:

• lower destructive thresholds
• expand trash coverage
• expand draft classes
• enable auto-unsubscribe
• lower auto-unsubscribe thresholds
• shorten unsubscribe inactivity windows
• relax protected-contact rules
• remove risk boosters

Review Method

Rescue analysis

• count archived threads later moved back to inbox
• count trashed items later restored
• count unsubscribed senders later manually re-engaged
• identify protected-class mistakes immediately

Draft analysis

• classify draft edits as light, medium, or heavy
• extract whether edits changed tone, facts, structure, or commitment level
• update voice rules only when patterns repeat

Confusion cluster analysis

• group repeated ambiguous threads
• identify missing rules or missing contact metadata
• propose one rule change at a time
