 - TLS reporting posture: delivered authenticated TLS-RPT upload for `.json`, `.json.gz`, and `.zip` attachments; duplicate-safe persistence by report ID and policy domain; daily session trends; top failure-cause grouping; affected-domain summaries; and explicit privacy controls that avoid storing message content or recipient data.
 - BIMI posture: delivered default-selector BIMI TXT validation, HTTPS logo/certificate URL checks, DMARC enforcement readiness checks, domain-detail evidence, and operator guidance for missing or blocked BIMI prerequisites.
+- Posture dashboard and operator playbooks: delivered a per-domain posture score, coverage cards for DMARC/SPF/DKIM/MTA-STS/BIMI, evidence-linked recommendations, provider-backed DNS drift summaries, and short remediation playbooks.
 - Extended DNS checks that support the posture surface (e.g., MX/BIMI; optional DANE/TLSA where relevant).

+### Posture Dashboard
+
+The domain detail page starts with an evidence-first posture dashboard. It
+summarizes coverage for DMARC, SPF, DKIM, MTA-STS, and BIMI, assigns a simple
+posture score, and shows each recommendation with links back to the DNS record,
+report trend, sending-source table, or posture evidence that triggered it.
+
+The same surface includes a **What Changed** panel when provider-backed DNS
+change tracking has observed additions, edits, or removals. Those summaries are
+designed for drift review: operators can see the previous and current values
+without reading logs.
+
+Operator playbooks sit beside the recommendations. They are short remediation
+checklists for common gaps such as missing SPF, missing DKIM, policy enforcement
+readiness, MTA-STS setup, or BIMI prerequisites.
+
 ### MTA-STS Posture
 
 The domain detail page checks `_mta-sts.<domain>` and fetches the policy from `https://mta-sts.<domain>/.well-known/mta-sts.txt`.
