Item	What it is
`pub struct ContactModule`	—
`ContactModule :: fn new() -> Self`	—
`ContactModule :: fn name(& self) -> & 'static str`	—
`ContactModule :: fn version(& self) -> & 'static str`	—

`api::contacts_admin`

Item	What it is
`pub const PERM_READ: & str`	Permission code required to read contact channels
`pub const PERM_WRITE: & str`	Permission code required to create/update/delete/set-primary.
`pub struct ListContactsQuery`	`GET /contacts` — `tenant_id` AND `party_id` are both required, no `#serde(default)`, matching `relationships_admin::ListRelationshipsQuery`'s contract exactly: a request for "every contact in the tenant" with no anchor party isn't served by this admin surface.
`pub struct TenantQuery`	`GET\
`pub enum ContactRequestError`	Errors raised before any query runs — either the domain crate's own validation (`ContactError`, reused rather than re-invented per Gate 0.5) or this router's own field-length ceiling (Gate 1.5.6 item 1, which the domain crate has no opinion on).
`fn to_dto(c : & Contact) -> ContactChannelDto`	Project a contact onto the wire DTO.
`fn contact_from_create(tenant_id : Uuid, req : & CreateContactChannelRequest,) -> Result <Contact, ContactRequestError>`	Build a new contact from a create request
`fn apply_update_fields(existing : & Contact, req : & UpdateContactChannelRequest,) -> Result <(ContactType, Option <ContactPurpose>, String, Option <String>, Option <String>,), ContactRequestError,>`	Resolve an update request against the existing row — fields absent from the request keep their existing value
`fn router <S>() -> Router <S> where S : Clone + Send + Sync + 'static, PgPool : FromRef <S>,`	Contacts admin router

Boundary

Reaches into domain, platform.

Shares tier application with 120 other crates: application-agreements, application-ai, application-analytics, application-approvals, application-assessments, application-audit-log, application-auth, application-billing, … (120 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._
