What .auDO observes
General-purpose public text records
.auDO preserves public TXT answers as direct evidence. Specific SPF and DMARC posture is derived separately from relevant records rather than treating all TXT content as mail policy.
Technical fields
Why it is observed
TXT records preserve visible policy and verification context
Why it matters
TXT evidence can show public mail-policy material, SaaS verification, domain validation and other control-plane artefacts.
What visible change may mean
A change may reflect provider verification, SaaS onboarding, validation, cleanup, policy tuning or routine maintenance.
Interpretation limits
TXT is a container, not a single posture signal
TXT records can contain unrelated operational evidence. Presence or change does not establish active use or the quality of any associated control.
Where to use this evidence
Use derived pages for mail-authentication posture
