+# GovOPlaN DMS
+
+Optional integration module for external document-management systems. The first concrete product profile targets d.velop d3 DMSApp and provides repository discovery plus digest-bound request planning. Real target writes remain disabled until a configured d3 tenant passes mapping, custody, reconciliation, and recovery tests.
+
+See [the DMS boundary](docs/DMS_BOUNDARY.md) and [the d.velop d3 integration profile](docs/DVELOP_D3_INTEGRATION.md).

+`govoplan-dms` owns document lifecycle and collaborative document-management
+semantics. It builds on files/storage providers but does not own low-level file
+storage or file connector implementations.
+
+This repository is currently a tag-only scaffold. It should gain package
+metadata and module manifests only after the first backend or WebUI slice is
+designed.
+
+See [docs/DMS_BOUNDARY.md](docs/DMS_BOUNDARY.md) for the boundary decision.

+# DMS Module Boundary
+
+`govoplan-dms` owns document lifecycle, collaboration, document evidence, and
+document governance. Files remain lower-level storage and provider integration.
+
+The core boundary decision register is in
+`/mnt/DATA/git/govoplan-core/docs/MODULE_ARCHITECTURE.md`.
+
+## Ownership
+
+DMS owns:
+
+- document records, versions, renditions, and document metadata
+- collaborative editing links and external office-suite session references
+- comments, reviews, approvals, locks, signatures, and checkout/checkin
+- document classification, retention inputs, legal hold, and archive handoff
+- document evidence references for cases, workflow, templates, forms, mail, and
+  reporting
+- external DMS/e-file/archive links and selected metadata synchronization where
+  a connector provides the protocol boundary
+
+## Boundary With Files
+
+`govoplan-files` owns:
+
+- stored file objects and blob/provider storage
+- file upload/download, file permissions, file spaces, and provider connectors
+- checksums, MIME type, file size, and low-level file metadata
+
+DMS should reference file objects through file capabilities and DTOs. It must
+not import file connector internals. A document version may point to a
+GovOPlaN-managed file, an external DMS object, or both.
+
+## External Collaboration
+
+Office/collaboration suites such as Collabora, OnlyOffice, Nextcloud Office, or
+OpenDesk document services should be integrated through connectors or
+capabilities. DMS owns the document session semantics and evidence; connectors
+own endpoint/profile health and protocol-specific clients.
+
+## Integrations
+
+- `govoplan-templates`: generates initial document content or rendered outputs
+- `govoplan-forms`: supplies submission data and attachment references
+- `govoplan-workflow` and `govoplan-cases`: attach documents to process state
+  and evidence
+- `govoplan-mail` and `govoplan-postbox`: send or expose document references
+- `govoplan-reporting`: exports reports as document evidence where needed
+- `govoplan-records`: classifies closed documents into file plans and archive
+  handoff
+
+## Candidate Capabilities
+
+- `dms.documents`
+- `dms.versions`
+- `dms.collaboration`
+- `dms.approvals`
+- `dms.locks`
+- `dms.legalHold`
+- `dms.externalReferences`
+
+## First Implementation Slice
+
+1. Define manifest metadata, permissions, and capability names.
+2. Add document/version/reference DTOs.
+3. Add one file-backed document version path through the files capability.
+4. Add locks and approval status as explicit document state, even if the first
+   implementation is simple.
+5. Add tests that DMS can run without external office-suite connectors and that
+   optional file integration uses capabilities.

+# d.velop d3 integration profile
+
+GovOPlaN's first concrete DMS product profile targets the d.velop d3 DMSApp HTTP interface. The slice deliberately separates discovery and request planning from effects.
+
+## Configuration boundary
+
+A tenant binding contains the HTTPS API base URL, repository ID, calling `Origin`, d3 source category, stable source ID, mapping revision, and an Access credential-envelope reference. The bearer token is resolved only for an outbound call and is never persisted in the DMS binding, plan, evidence, or diagnostics.
+
+The source category and source properties must be mapped by the d3 tenant administrator. GovOPlaN does not infer a document type from a repository response or silently adapt when that mapping changes.
+
+## Preflight and plan
+
+Preflight reads the DMSApp repository catalog, the selected repository, and its object definitions. It records observation time and canonical response digests. A successful preflight means that discovery and authentication worked; it does not prove that a source mapping accepts GovOPlaN data.
+
+The store-plan builder produces the documented `o2m` request shape with stable GovOPlaN package, record, revision, manifest digest, purpose, and mapping-revision properties. It never sends the request. The plan digest is the review boundary for a later target-tested write implementation.
+
+## Enablement gates
+
+Real Records dispatch remains fail-closed until target evidence demonstrates all of the following:
+
+- repository and object-definition discovery through the deployed gateway;
+- administrator-reviewed source-property mapping;
+- successful storage and correlation lookup by package ID and manifest digest;
+- an unambiguous custody receipt or an explicit statement that d3 is only a DMS copy target;
+- timeout and unknown-outcome reconciliation before retry;
+- correction, quarantine, and recovery exercises; and
+- credential rotation without exposing bearer values.
+
+Until those gates are met, the `records.archive.dvelop_d3` capability reports unhealthy and rejects dispatch. Records retains its approved, digest-bound package and does not claim external custody.
