+
+## Documentation Contract
+
+- Treat documentation as part of every behavior change. Update this module's manifest-driven `DocumentationTopic` contributions for affected user and administrator behavior.
+- Keep feature content here; `govoplan-docs` projects it without importing Addresses internals.
+- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.

+## Boundaries
+
+- Keep identity and organization ownership in their respective modules.
+- Expose optional integrations through Core capabilities and typed references.

 # GovOPlaN Addresses
 
-`govoplan-addresses` is the planned reusable address and recipient-source
-module. It should own long-lived address directories and make them available to
-campaigns, mail, forms, reporting, portal, and postbox modules through platform
-capabilities.
+<!-- govoplan-repository-type:start -->
+**Repository type:** module (domain).
+<!-- govoplan-repository-type:end -->
+
+`govoplan-addresses` is the reusable address and recipient-source module. It
+owns long-lived address directories and contact points and makes them available
+to consumers through platform capabilities.
 
 The campaign module may import campaign-local recipient tables, but reusable
 address management belongs here.
 
+## Current State
+
+Milestone 1 is implemented. The module now owns persistent local address books
+and contact CRUD under `/api/v1/addresses`, contributes `/address-book` to the
+WebUI, and registers address permissions, role templates, database migrations,
+tenant summaries, and uninstall guards.
+
+The first UI supports user, group, tenant, and system-scoped address books,
+multi-value contact methods, soft deletion, restore, read-only lookup/search,
+and vCard import/export for common contact fields. Imported vCards preserve
+source payload and revision metadata for later sync/conflict work.
+
+The backend and WebUI also support classical address lists: reusable groupings
+of contacts or specific contact methods within one address book. Campaigns can
+import address books and address lists through the core-mediated
+`addresses.recipient_source` capability without importing address-module
+internals. Broader operational `Verteiler` with mixed users, identities,
+groups, functions, raw recipients, and nested lists belong in
+`govoplan-dist-lists`.
+
+The backend now also contains connector-neutral sync infrastructure. Address
+books can be bound to external sources, sync attempts can record status,
+tokens, ETags, revisions, diagnostics, tombstones, and conflicts, and read-only
+or one-way-import sources make the owning address book read-only for normal
+write paths. CardDAV discovery, source binding, dry-run preview, inbound vCard
+sync, outbound create/update/delete for writable CardDAV sources, diagnostics,
+tombstones, conflict persistence, source disconnect/delete UX, and a first sync
+inspection UI are implemented. The conflict review UI compares stored local and
+remote field payloads, can apply a stored remote vCard payload, and supports
+manual per-field local/remote merge choices.
+
+Address quality and duplicate handling are implemented as an operator workflow.
+Contact points retain both their original and normalized values, field-level
+provenance is append-only, and current quality states can mark a point valid,
+invalid, returned, stale, or undeliverable. Those states flow into recipient
+resolution with stable reason codes. The quality dialog shows bounded,
+explainable duplicate suggestions and a correction queue. Merges record explicit
+survivorship decisions, repair address-list memberships, preserve redirects for
+stored contact references, and can be undone or split while the post-merge
+evidence hash still matches.
+
+API-managed CardDAV credentials are encrypted inside the source record. Source
+deletion physically removes that credential material and records a non-secret
+audit event in the same database transaction; destructive module retirement
+audits every remaining credential before the owning tables are dropped. Legacy
+external references are detached but are never sent to a secret provider for
+deletion because Addresses cannot prove that it owns them.

-## First Capability
+## Capabilities
 
-The first useful contract should be a read-only recipient-source capability,
-for example `addresses.recipientSource`.
+The module exposes core-mediated capabilities for:
 
-It should let a consumer request a stable snapshot containing:
+- `addresses.lookup`: read-only contact/recipient lookup for autocomplete.
+- `addresses.recipient_source`: immutable recipient snapshots for campaign,
+  reporting, mail-build, forms, portal, and postbox workflows.
+- `addresses.contact_writer`: address-book-scoped write decisions and contact
+  creation for local or otherwise writable sources.
+- `addresses.contact_point_resolution`: purpose-aware, channel-neutral
+  resolution and immutable snapshots for email, postal, internal-mail, and
+  portal targets.
+- `addresses.people_search`: privacy-aware contact candidates for shared people
+  pickers.
+- `distribution.recipient_channel_facts`: current channel, governance, and
+  quality facts for distribution and Policy consumers.
+
+`addresses.recipient_source` returns:
 
 - source id and display label
 - normalized recipient rows
-- email and postal address fields
-- legal-basis and consent metadata
+- email recipient fields
 - source update marker
 - provenance fields suitable for audit and campaign reports
 
-Consumers must store their own immutable snapshot when they need historical
-evidence. The addresses module remains the owner of the reusable source, not of
-the consumer's historical records.
+Recipient sources currently include complete address books and classical
+address lists. Address-list source IDs use `addresses:address_list:<id>` and
+preserve the address-list entry ID in recipient provenance. Address-list entries
+may point at a whole contact, a concrete email address, or a concrete postal
+address. Email-oriented consumers snapshot email targets and whole-contact
+entries with a usable email address; postal-only entries remain valid list
+members for later postal/document workflows.
+
+Legacy `addresses.recipient_source` consumers must store their own immutable
+snapshot when they need historical evidence. Channel-neutral consumers may use
+the dedicated freeze operation described below. The addresses module remains
+the owner of reusable sources; domain consumers remain responsible for linking
+their own records to snapshot evidence. Consumers must resolve these
+capabilities through the platform registry and must not import address
+ORM/service internals.
+
+`addresses.contact_writer` returns an explicit decision before a consumer shows
+or executes write actions: allowed/blocked, reason, user-facing message,
+required scopes, source kind, read-only state, and provenance. The decision is
+address-book specific; broader policy modules may later contribute to the same
+decision path, but consumers should not import or duplicate policy logic.
+
+For channel-neutral consumers, `addresses.contact_point_resolution` supersedes
+the email-only shape without removing it. It accepts local contact IDs and
+stable provider references such as `idm:identity:<id>`, applies an effective
+date, communication purpose, address purpose, fallback rule, locale, and
+domestic/international postal formatting, and returns candidates plus excluded
+targets with stable reason codes. Bounded previews are live. A frozen snapshot
+stores the complete values, source and governance revisions, provenance, and a
+deterministic hash in Addresses so later contact edits cannot rewrite evidence.
+
+The corresponding HTTP API is available below `/api/v1/addresses`:
+
+- `POST /contact-points/resolve`
+- `POST /contact-point-sources/preview`
+- `POST /contact-point-snapshots`
+- `GET /contact-point-snapshots/{snapshot_id}`

+# GovOPlaN Addresses Module Architecture
+
+## Decision
+
+`govoplan-addresses` owns reusable contact and recipient-source data. Campaigns,
+mail, scheduling, portal, postbox, forms, reporting, and other modules consume
+address data through core-mediated capabilities and APIs, not by importing
+address-module internals.
+
+The implementation reference for contact data is vCard. CardDAV is the primary
+address-book sync protocol. LDAP/Active Directory, Exchange/Microsoft 365,
+Google Contacts, CSV/XLSX, LDIF, and batch vCard import/export are connector
+targets layered on top of the same local model and sync contracts.
+
+## Ownership
+
+`govoplan-addresses` owns:
+
+- scoped address books
+- vCard-compatible contacts and postal/email/phone contact-point data
+- vCard import/export and vCard-compatible field mapping
+- reusable recipient sources and classical address lists
+- contact tags, categories, communication preferences, consent, and legal basis
+- deduplication, merge, address quality checks, and suppression lists
+- contact provenance, audit history, soft delete, and restore
+- external-source bindings, sync state, conflicts, and read-only source markers
+
+It does not own:
+
+- campaign-local recipient snapshots and evidence
+- mail transport, mailbox access, or delivery queues
+- calendar events or iCalendar event storage
+- global identity authentication or authorization decisions
+- IDM identities, typed groups, effective-dated relationships, or identity
+  lifecycle state
+- organization structures, units, function definitions, or function
+  assignments
+- operational distribution lists/`Verteiler` with mixed address contacts, IDM
+  identities/groups, functions, raw targets, Dataflow rows, and nested lists
+
+## Scopes
+
+Address books can live in these scopes:
+
+- `user`: personal address books and remembered contacts
+- `group`: team/shared address books
+- `tenant`: tenant-wide directories and approved shared lists
+- `system`: platform-wide public/shared directories where policy allows it
+
+The scope determines visibility, default permissions, sync credentials, and
+whether downstream modules may reuse or mutate entries.
+
+## Data Model Principles
+
+The canonical model should preserve enough vCard semantics to round-trip common
+fields:
+
+- name components and formatted names
+- nicknames and display names
+- email addresses, phone numbers, postal addresses, URLs, notes, categories
+- organization, title, role, department, `KIND`, and `RELATED` values needed for
+  vCard round-trip compatibility
+- birthday/anniversary where allowed by policy
+- photos/avatars where storage and privacy policy allow them
+- calendar or scheduling addresses where present
+- source IDs, revisions, ETags, sync tokens, and provenance
+
+The model should support both normalized query fields and a preserved original
+representation for import/export and conflict handling.
+
+The local baseline implements scoped address books, contacts, normalized
+email/phone/postal-address tables, tags, source kind/reference fields,
+first-class source payload/revision fields, preserved original contact-point
+values, and append-only field provenance. Imported
+vCards preserve raw source payload and revision metadata for audit/debugging.
+Sync sources, attempt state, tombstones, conflicts, and diagnostics are now
+first-class backend tables and API resources. Connector-specific diffing,
+CardDAV discovery, and conflict-resolution UI remain part of the connector
+milestones.
+
+## Capabilities
+
+The first stable capabilities are:
+
+- `addresses.recipient_source`: return immutable recipient snapshots for
+  campaigns, forms, reporting, and other send/build workflows.
+- `addresses.lookup`: provide read-only lookup and autocomplete for mail,
+  campaign, scheduling, postbox, portal, and case workflows.
+- `addresses.contact_writer`: provide address-book-scoped write target decisions
+  and contact creation for local or otherwise writable sources.
+- `addresses.contact_point_resolution` version 1.x: resolve channel-neutral
+  contact points and freeze immutable recipient evidence.
+
+Capabilities use DTOs and source IDs. Consumers must not receive ORM objects or
+write address tables directly. Consumers that need historical evidence must
+store their own immutable snapshot with source ID, source revision, and
+provenance; they must not treat live address records as historical evidence.
+
+`addresses.recipient_source` exposes both complete address books and classical
+address lists. Address-book sources use `addresses:address_book:<id>`.
+Address-list sources use `addresses:address_list:<id>` and include the
+address-list entry ID in each recipient's provenance. The legacy snapshot DTO
+remains email-oriented for compatible campaign consumers.
+
+Channel-neutral consumers use `addresses.contact_point_resolution`, which
+supports email, postal, internal-mail, and portal targets, including postal-only
+address-list entries. Requests make effective date, communication purpose,
+address purpose, fallback behavior, locale, and domestic/international postal
+formatting explicit. Results retain stable subject/contact/contact-point IDs,
+source, preference and consent revisions, provenance, and reasons for excluded
+or unresolved candidates.
+
+Live previews are bounded to 500 rows per page and 20,000 source members per
+request. Frozen snapshots persist resolved values and exclusions with a
+deterministic hash; reading a snapshot never resolves the live contact again.
+Mixed-audience expansion and final cross-provider Policy/channel decisions
+remain owned by Distribution Lists and Policy. The contract is defined in Core,
+and Addresses does not import IDM, Organizations, or Distribution Lists
+implementations.
+
+The writer capability is intentionally address-book specific. It answers
+whether the current principal may perform an operation such as `create_contact`,
+`update_contact`, or `delete_contact` against a concrete address book. The
+decision payload includes:
+
+- `allowed`
+- stable `reason`
+- user-facing `message`
+- required scopes
+- source kind
+- read-only state
+- scope and tenant provenance
+
+Policy modules or connector sync state may later add inputs to this decision,
+but consumers must continue to call the address capability/API instead of
+importing policy logic or address services directly. Disabled or read-only UI
+actions should surface the returned `message` on hover.
+
+## Sync Model
+
+Every synced address book tracks or can track:
+
+- connector type and external account/source
+- external address-book ID and display name
+- local address-book scope
+- sync direction: read-only, one-way import, one-way export, two-way
+- sync token, ETag/revision, last successful sync, last attempted sync
+- deleted markers/tombstones
+- conflict status and resolution decision
+- connector diagnostics and rate-limit/backoff state
+
+Sync conflict UX must show the local value, remote value, source, timestamp, and
+available action. Silent overwrite is not acceptable.
+
+Sync infrastructure is intentionally connector-neutral. CardDAV, LDAP,
+Exchange/Microsoft 365, Google Contacts, CSV/XLSX/LDIF import profiles, and
+future connectors must write through `addresses_sync_sources` and related
+records instead of inventing connector-specific status tables. Connector jobs
+may mark a source `running`, `succeeded`, `failed`, or `conflict`; read-only and
+one-way-import sources propagate a read-only decision to the owning address
+book, which in turn blocks normal contact writes through the existing writer
+capability/API.
+
+The first CardDAV implementation supports discovery, source binding, dry-run
+preview, inbound vCard sync, outbound create/update/delete for writable
+sources, sync-token/full-sync fallback, tombstones, diagnostics, and persisted
+conflicts. Outbound writes use ETag preconditions; stale local state must become
+a conflict instead of silently overwriting remote data. The first conflict
+review UI compares stored local and remote field payloads and can apply a
+stored remote vCard payload or a manual per-field local/remote merge payload.
+Source disconnect/delete removes the source binding and related sync records
+while keeping local contacts. Because API-managed CardDAV credentials are
+encrypted in the source row, the same transaction physically removes their
+ciphertext and emits non-secret credential-deletion audit evidence. Destructive
+module retirement audits all remaining owned credential material before table
+removal. An unowned legacy reference is detached rather than passed to an
+external secret provider.
+
+LDAP and Active Directory use the same source, plan, diagnostic, tombstone, and
+provider-health records. Endpoints must use LDAPS or StartTLS and may reference
+only a visible reusable credential envelope; bind secrets are never copied into
+source metadata. Root-DSE discovery returns candidate base DNs. A configured
+source performs bounded paged searches and maps explicit attributes to contact
+fields. Stable source keys plus `modifyTimestamp`, `uSNChanged`, `entryCSN`, or
+a deterministic attribute digest make refreshes idempotent. Only a complete
+successful search can infer deletion. A timeout, bind failure, malformed entry,
+duplicate key, or configured entry limit retains existing contacts and reports
+the source as failed/stale instead of creating tombstones.
+
+## Static Tabular Imports
+
+CSV and XLSX use versioned, scoped mapping profiles rather than live sync
+sources. Profiles retain delimiter, encoding, header or worksheet selection,
+stable source-key mapping, field mappings, locale and tags, row limits, and
+explicit duplicate, blank-value, and existing-contact policies. Updating a
+profile creates an immutable next version; prior import runs continue to point
+at the reviewed version.
+
+Preview decodes at most 10 MB and 10,000 rows, validates every referenced
+column and source key, and returns an effect or diagnostic for every data row.
+XLSX parsing is read-only; formulas are rejected and macros/legacy workbook
+formats are not accepted. The input SHA-256 and deterministic plan hash are
+stored with full effects. Apply uses exactly that plan, rejects changed target
+contacts, and is idempotent. Created IDs and pre-update snapshots provide a
+guarded rollback: rollback proceeds only while each imported contact still
+matches its recorded post-apply hash. Arbitrary transforms remain Dataflow's
+responsibility; Files and Datasources are optional origins, not prerequisites
+for direct upload.
+
+## Quality, Deduplication, And Recovery
+
+Quality is evidence about a concrete contact point, separate from communication
+consent or Policy. Effective decisions use one of `valid`, `invalid`,
+`returned`, `stale`, or `undeliverable`, retain reason/evidence references, and
+end an overlapping prior decision rather than rewriting history. Recipient
+capabilities project the current decision into a stable status and reason code;
+consumers can exclude invalid points or explicitly handle stale points without
+copying Addresses rules.
+
+Duplicate suggestions are bounded to 500 scanned contacts and 100 returned
+pairs. Every score is composed from visible exact-match features such as a
+normalized email, phone, postal address, or name/organization combination. A
+suggestion does not mutate data.
+
+A merge is an explicit, transactional decision. The caller selects a surviving
+contact, scalar-field sources, source precedence, and either union or
+survivor-only contact-point handling. The merge records before/after evidence
+and hashes, field/contact-point decisions, copied quality/governance evidence,
+and stable loser-to-winner redirects. Address-list entries are repointed in the
+same transaction. Undo and split restore the recorded contacts and memberships
+only when the current evidence still matches the post-merge hash; later edits
+must be reconciled first. Core change-sequence evidence is always written. Core
+audit entries are written by HTTP mutation routes without requiring the
+optional Audit module.
+
+## Connector Direction
+
+Implement connectors in this order:
+
+1. vCard import/export and batch import.
+2. CardDAV address books.
+3. LDAP/Active Directory read-only directories and reusable CSV/XLSX mapping
+   profiles (implemented).
+4. [Microsoft Graph for Microsoft 365](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/16),
+   [explicit on-premises Exchange profiles](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/17),
+   and [Google People](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/18).
+5. [LDIF import](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/20)
+   and [selective/large-batch vCard workflows](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/21).
+
+The live connectors use the existing sync-source model. LDAP is read-only;
+Microsoft Graph and Google start with read-only/import and gate two-way mode on
+conditional-write and outcome-reconciliation tests. On-premises Exchange first
+probes and records an explicit supported server/API profile. CSV/XLSX, LDIF,
+and uploaded vCard are static one-way imports, not writable remote sources.
+
+Connector runtime behavior should reuse shared connector concepts where useful:
+configured endpoints, credentials, dry-run, diagnostics, rate limits, and audit
+events. The shared contract work is tracked in
+[`govoplan-connectors#8`](https://git.add-ideas.de/GovOPlaN/govoplan-connectors/issues/8);
+Addresses remains the owner of contact mapping, provenance, quality, and sync
+state.
+
+## Cross-Module Integration
+
+Campaigns should consume `addresses.recipient_source` through the platform
+registry and freeze snapshots into campaign versions. Mail should consume
+`addresses.lookup` for autocomplete and `addresses.contact_writer` for "add
+contact" workflows. Scheduling should use lookup for attendees and organizers.
+Portal, postbox, cases, forms, and reporting should link to contact records by
+stable IDs while keeping their own domain evidence. Cross-module UI must hide
+write actions when no writable target exists, or show the writer decision
+message when a disabled action remains visible for context.
+
+Operational distribution lists and reusable dynamic segments belong in
+`govoplan-dist-lists`. They may consume address lists as one entry type, but
+they own mixed recipient expansion for address contacts, IDM identities and
+typed groups, organization units, functions/effective incumbents, raw targets,
+Dataflow-backed rows, and nested lists. Workflow owns `Umlauf` execution state;
+distribution lists define who is included, not how work circulates.
+
+Organizations owns unit and function definitions. IDM owns effective-dated
+identity-to-function assignments and typed group relationships. Identity
+lifecycle status is not a business audience status; a selectable business
+status is represented by a group, function, or effective-dated relationship.
+Addresses may link contact points to stable provider references without copying
+those provider-owned facts.
+
+## Deferred Work
+
+The following are valuable but not required for the first functional milestone:
+
+- two-way sync conflict UI
+- Microsoft/Google connectors
+- richer vCard `KIND`/`RELATED` round-trip and provider-reference linking
+- advanced consent-policy automation
+- contact activity timeline across all modules

+Status: implemented. The persistent backend, router, migration, permissions,
+role templates, lookup endpoint, restore support, multi-value contact editor,
+and first WebUI are in place.

+  methods, postal addresses, tags, and provenance
+- [x] add permissions and role templates for viewing and managing address books
+- [x] implement address-book CRUD API
+- [x] implement contact CRUD API
+- [x] implement scoped WebUI views for user, group, tenant, and system books
+- [x] support soft delete
+- [x] add restore API/UI for soft-deleted address books and contacts
+- [x] expose read-only contact lookup for the WebUI
+
+Exit criteria:

+- [x] a user can create a personal book and contacts
+- [x] address data survives restart and appears in the address-book UI
+- [x] disabled or read-only actions explain why they are unavailable
+
+## Milestone 2: vCard Foundation
+
+Goal: make the model standards-based before adding sync.
+
+Primary issue: `govoplan-addresses#4`.
+
+Status: implemented. The module can import and export common vCard fields for
+local books, preserves imported raw vCard payload and revision metadata in
+first-class source fields, reports field/card import issues, and has round-trip
+and partial-import tests. Full two-way connector conflict resolution remains in
+the sync milestones.
+
+Tasks:
+
+- [x] define vCard-compatible DTOs
+- [x] preserve original imported vCard data and normalized query fields
+- [x] import `.vcf` files into a selected address book
+- [x] export contacts/address books as vCard
+- [x] add validation for common vCard fields
+- [x] add tests for round-trip import/export of names, emails, phones, postal
+  addresses, organization fields, notes, categories, and URLs
+- [x] add field/card validation messages for batch import
+- [x] promote original payload and revision handling into first-class contact
+  source fields
+
+Exit criteria:
+
+- [x] common vCard files can be imported and exported without losing core fields
+- [x] normalized search fields are populated during import
+- [x] invalid entries produce field-level actionable validation messages
+
+## Milestone 3: Core Capabilities
+
+Goal: allow other modules to use addresses without dependencies.
+
+Primary issue: `govoplan-addresses#5`.
+
+Tasks:
+
+- [x] implement `addresses.lookup`
+- [x] implement `addresses.recipient_source`
+- [x] define immutable recipient snapshot DTOs
+- [x] expose source provenance in capability responses
+- [x] expose classical address lists as `addresses.recipient_source` sources
+- [x] expose versioned channel-neutral contact-point resolution for local and
+      stable provider subject references
+- [x] support purpose/address-purpose selection, deterministic fallback,
+      locale, and domestic/international postal rendering
+- [x] add bounded source previews and immutable postal/email snapshots
+- [x] add module presence/capability tests
+- [x] document consumer rules for campaign, mail, scheduling, portal, postbox, and
+  reporting
+
+Exit criteria:
+
+- [x] campaign can request a recipient source via core-mediated capability
+- [x] mail/scheduling can request autocomplete candidates via core-mediated lookup
+- [x] consumers do not import `govoplan_addresses`
+- [x] postal-only contacts/list entries can be resolved without changing the
+      legacy email recipient-source contract
+
+## Milestone 4: Campaign Integration
+
+Goal: replace campaign-local reusable address concepts with address-module
+sources.
+
+Primary issue: `govoplan-campaign#55`.
+
+Tasks:
+
+- [x] add campaign recipient-source picker when `addresses.recipient_source` exists
+- [x] snapshot selected address-source rows into the campaign version
+- [x] store source ID, revision, and provenance in campaign evidence
+- [x] show stale-source warnings when an address source changed after selection
+- [x] keep campaign import for one-off local recipient data
+- [x] define classical address lists as reusable address-domain sources
+- [x] add address-list selection and management UI in addresses/campaign
+- [ ] define segments/dynamic filters before exposing them as campaign sources
+      Deferred deliberately: classical address lists are stable now; dynamic
+      segments need their own filter model, stale-source semantics, and audit
+      evidence before campaign can snapshot them safely.
+
+Exit criteria:
+
+- [x] campaign works without addresses installed
+- [x] campaign offers address-source selection when addresses is installed
+- [x] built campaigns remain auditable after source contacts change
+
+## Milestone 5: Mail And Scheduling Integration
+
+Goal: make contacts visible where users naturally need them.
+
+Primary issues: `govoplan-mail#13` and `govoplan-scheduling#2`.
+
+Tasks:
+
+- [x] add mail recipient/autocomplete integration through `addresses.lookup`
+      at API/capability level; visible compose UI reuse follows when mail
+      compose exists
+- [x] expose `addresses.contact_writer` for explicit address-book write
+      decisions, required scopes, read-only/source reasons, and provenance
+- [ ] add "add sender/contact" actions in consuming UIs by using
+      `addresses.contact_writer`
+- [x] add scheduling attendee/organizer lookup integration
+- [x] preserve module independence when addresses is absent
+
+Exit criteria:
+
+- [x] mail and scheduling build without addresses installed
+- [x] when addresses is installed, lookup improves recipient/attendee entry
+- [x] address write decisions expose why actions are unavailable for read-only
+      sources, deleted books, missing scopes, or unsupported operations
+- [ ] consuming UI write actions are hidden or explained with the
+      `addresses.contact_writer` decision payload
+
+## Milestone 6: Sync Infrastructure
+
+Goal: prepare external address books without committing to all connectors at
+once.
+
+Primary issue: `govoplan-addresses#6`.
+
+Status: implemented for the first connector path. The connector-neutral backend
+substrate is in place: sync sources, source status, read-only propagation,
+tombstones, conflicts, diagnostics, attempt transitions, dry-run preview,
+audit-event emission, and a first sync inspection UI.
+
+Tasks:
+
+- [x] add address-source connector configuration
+- [x] add sync state, ETags, revisions, tokens, tombstones, and conflict records
+- [x] add sync diagnostics
+- [x] add audit events for sync attempts, conflicts, previews, completions, and
+      resolutions
+- [x] support read-only and writable source flags
+- [x] add dry-run and preview for connector changes
+- [x] add admin/user UI for source status, diagnostics, tombstones, and conflicts
+
+Exit criteria:
+
+- [x] a connector can report planned creates/updates/deletes before applying them
+- [x] sync failures are visible in the UI
+- [x] conflicts are persisted and do not silently overwrite data
+
+## Milestone 7: CardDAV
+
+Goal: implement the first real standards-based sync connector.
+
+Primary issue: `govoplan-addresses#7`.
+
+Status: implemented for the first standards-based sync path. Discovery, source
+binding, full/sync-token inbound sync, outbound create/update/delete for
+writable sources, dry-run preview, diagnostics, tombstones, and persisted
+conflict records are implemented. Source disconnect/delete UX and conflict
+review are implemented; stored remote vCard payloads can be applied from the
+review UI, and manual per-field local/remote merge choices are supported.
+
+Tasks:
+
+- [x] add CardDAV account/address-book discovery
+- [x] sync vCard resources into scoped address books
+- [x] support read-only and writable source flags
+- [x] push local creates, updates, and deletes to writable CardDAV sources with
+      ETag preconditions
+- [x] handle ETag changes, deletes, and conflicts
+- [x] add connection discovery and diagnostics
+- [x] add source disconnect/delete UX that keeps local contacts
+- [x] add conflict review UI with local/remote field comparison
+- [x] apply stored remote vCard payloads from conflict resolution
+- [x] support manual per-field local/remote merge choices for stored vCard payloads
+
+Exit criteria:
+
+- [x] a CardDAV source can be connected, synced, and inspected
+- [x] CardDAV source disconnect/delete UI
+- [x] contacts can be refreshed without duplicating entries
+- [x] conflict and permission states are visible to the user
+- [x] outbound CardDAV writes for writable remote books
+- [x] field-level conflict review UI
+- [x] manual per-field merge editing
+
+## Milestone 8: Additional Connectors And Advanced Address Features
+
+Goal: expand beyond CardDAV after the model and sync engine are stable.
+
+Primary issues: `govoplan-addresses#8`, `govoplan-addresses#9`,
+`govoplan-addresses#10`, and `govoplan-connectors#8`.
+
+Tasks:
+
+- [ ] [LDAP/Active Directory read-only directory connector](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/15)
+- [ ] [Microsoft Graph contacts connector for Microsoft 365](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/16)
+- [ ] [On-premises Exchange connector profile](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/17)
+- [ ] [Google People contacts connector](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/18)
+- [ ] [Reusable CSV/XLSX import mapping profiles](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/19)
+- [ ] [Bounded LDIF import profile](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/20)
+- [ ] [Selective and large-batch vCard workflows](https://git.add-ideas.de/GovOPlaN/govoplan-addresses/issues/21)
+- [x] classical address-list UI; reusable static/dynamic operational segments move
+  to `govoplan-dist-lists`
+- [x] operational distribution lists move to `govoplan-dist-lists`
+- [x] consent, legal-basis, suppression, and communication preferences
+- [x] bounded, explainable deduplication and reversible merge/split workflow
+- [x] contact-point quality states, normalization, original-value preservation,
+      field provenance, and correction dashboard
+- [x] stable redirect resolution for merged contact references
+- [ ] richer vCard `KIND`/`RELATED` round-trip and stable links to IDM/Organizations
+
+Exit criteria:
+
+- each connector or advanced feature can be enabled independently
+- users can understand where data came from and whether they may edit it
+- downstream modules can safely use contacts without owning them
+
+Issues #9 and #10 are implemented. Issue #8 is complete as a portfolio split:
+issues #15-#21 independently track each connector/import profile with explicit
+direction, dry-run, diagnostics, provenance, recovery, and module-independence
+requirements.
+
+## First Implementation Recommendation
+
+Start with Milestone 1 and enough of Milestone 2 to define the data model
+correctly. Do not start CardDAV before the local vCard-compatible storage and
+API are stable.

+## Consequence And Availability Rules
+
+- User, group, tenant, and authorized system scopes determine discovery and
+  management authority. Visible inherited or external sources can be read-only.
+- Address lists group contact points in one address book. Cross-module reusable
+  recipient expansion remains owned by Distribution Lists.
+- Archive/delete actions are confirmed and preserve governed history according
+  to retention. External-source disconnect retains local contacts but removes
+  source diagnostics and conflict state as explicitly stated.
+- Imports and synchronization separate preview from apply; incomplete external
+  reads never infer deletions.
+- Merge and communication-governance operations append auditable evidence and
+  never silently erase prior state.
+- Request feedback is rendered as a compact shared alert over the full-height
+  workspace. It does not become a grid row or displace the source, contact, and
+  detail columns.
+
+Backend and WebUI manifests publish matching route/section/action surfaces.
+English and German catalogues include the owned interaction vocabulary; major
+object drafts are guarded, and optional modules remain behind declared
+capabilities rather than private imports.

+# Address Quality And Reversible Merges
+
+## Operator Workflow
+
+Open the shield action for a selected address book to review its quality. The
+dialog shows:
+
+- the number of contacts and contact points in the bounded scan
+- current invalid, returned, stale, and undeliverable contact points
+- explainable duplicate suggestions with their score inputs
+- active and recovered merge records
+
+Each contact point also has a `Quality` action in the contact detail. Recording
+a new state ends an overlapping current state and retains both entries in
+history. Use a stable reason code and an evidence reference when the state came
+from delivery, import, or correction evidence.
+
+`valid` makes the point normally usable. `invalid`, `returned`, and
+`undeliverable` make it invalid for recipient resolution. `stale` remains a
+distinct status so a downstream workflow can warn, request confirmation, or
+block according to Policy. A later `valid` decision is a correction; it does
+not delete the earlier evidence.
+
+## Duplicate Review
+
+Suggestions do not merge automatically. The score is the bounded sum of named
+exact-match features. The operator chooses the surviving contact and whether to
+combine unique contact points or retain only the survivor's points. The API can
+additionally select the source contact for each scalar field and rank source
+kinds.
+
+A successful merge:
+
+- archives each duplicate and redirects its stable contact ID to the survivor
+- records scalar and contact-point survivorship decisions
+- carries field and contact-point source provenance forward
+- copies applicable quality and communication-governance evidence
+- repoints address-list entries to the survivor and mapped contact point
+- stores deterministic before/after evidence hashes
+- emits core change-sequence and audit evidence
+
+The merge history offers `Undo` and `Split`. Both restore the exact recorded
+pre-merge contacts and list memberships. Recovery is deliberately rejected when
+the contact or membership evidence changed after the merge. Reconcile those
+later edits before retrying; the system does not silently discard them.
+
+## Consumer Contract
+
+Consumers resolve live contacts through `addresses.contact_point_resolution` or
+`distribution.recipient_channel_facts`. They receive quality status, stable
+reason codes, evidence provenance, and the current source revision. Consumers
+must not read Addresses tables or recreate quality rules. A workflow requiring
+historical proof freezes a contact-point snapshot before delivery.
+
+The duplicate and quality endpoints are bounded. `truncated=true` means the
+operator should narrow the source or run a staged API review; it does not mean
+that the unreturned contacts were found clean.
