- Corpus and permission are explicit
- Define property, service, period, source, collection method, invited or exposed population, approved purpose, allowed fields, access, retention and deletion; preserve original items and edits; and keep public availability separate from unrestricted reuse.
- Taxonomy is versioned and reversible
- Use multi-label definitions with inclusions, exclusions, examples, severity, unknown and abstain; preserve supporting spans, model and translation versions; sample human review; record disagreement and correction.
- Sensitive feedback receives qualified review
- Route safety, discrimination, harassment, safeguarding, health, security, payment, access, legal, named-staff, compensation and formal-complaint content promptly; minimize exposure and never let an aggregate delay an individual response.
- Denominators and sample limits stay visible
- Show what each count and rate divides by, response and channel coverage, nonresponse, language mix, duplicate authors, seasonality, campaigns, property changes, missing metadata and small-group suppression; never generalize beyond the corpus.
- Themes remain inspectable and non-causal
- Preserve theme members, exemplars, exclusions, period, segment, method and stability; distinguish volume, rate, alert and operational importance; require other evidence and accountable investigation before any root-cause conclusion.
- Action and later outcome remain linked
- Name issue, complaint and action owners, preserve decisions and appeal paths, separate people decisions, track completion and reopening and compare later service and feedback with attribution, mix and measurement changes visible.
