Backing store and queries for the mailbox sender-avatar chain. SenderIdentityEntity is the durable tier of the avatar cache. org_id is part of the natural key rather than decoration: USERS.EMAIL is unique only per security provider, so an answer derived from tenant data must not be visible to another tenant. External-tier answers (BIMI/favicon/Gravatar) are genuinely global and share a sentinel org so every tenant shares the hit rate. Misses are stored as rows, not absences — without that, every unresolvable sender re-runs the whole provider chain on every inbox poll. OrgAvatarSettingsEntity splits the chain by what actually leaves the building. The identity tier defaults OFF because it discloses a digest of a correspondent's full address to a third party, which on a lending CRM is a decision about a borrower identifier rather than a display preference. The repository additions exist because none of this was reachable before: - ContactEmailRepository had no lookup by address at all — only substring LIKE for the autocomplete — so a contact that had a photo could not be resolved from a From: header. - Member/User batch lookups are org-scoped and take pre-lowercased input. LOWER() is applied to the stored column only; emails are persisted verbatim (EmbEmail has no normalizer) and CockroachDB equality is case-sensitive. - The avatar-id projections return ids rather than entities on purpose. Both Member.avatar and User.avatar are lazy associations onto a JOINED hierarchy: a caller outside a transaction gets LazyInitializationException, and one inside gets a base-type proxy that never narrows to AvatarPhoto, putting the file extension needed to build the URL out of reach. - **************** replaces a findAll() full-table scan that ran once per indexed message. PublicHostGuard is shared rather than duplicated because it is a security control: it decides whether an address is somewhere we will send a request that an untrusted party chose. Tested against the real bypass techniques — IPv4-mapped IPv6, 6to4, NAT64, CGNAT and link-local metadata. Right 177 gates the disclosure decision.
