 GovOPlaN Files is the managed file module. It bundles backend storage APIs and the Files WebUI package so file features can be installed as one module.

-The campaign module can integrate with files when both modules are installed, for example for managed attachment selection and campaign file sharing.
+The campaign module can integrate with files when both modules are installed,
+for example for managed attachment selection and campaign file sharing. Files
+does not import campaign internals; campaign share/existence checks use the core
+`campaigns.access` capability registered by the campaign module.
 
 Platform RBAC and governance rules are documented in `govoplan-core/docs/`.
 
+Managed files can carry source provenance for connector and import workflows.
+Upload callers may provide `source_provenance_json` and `source_revision`; the
+module stores those values under file metadata, returns normalized
+`source_provenance` and `source_revision` fields in file responses, and carries
+them into managed campaign attachment matches for frozen execution evidence.
+
+Connector policy preflight is available through
+`POST /api/v1/files/connector-policy/evaluate`, and provenance-bearing uploads
+can pass `connector_policy_json` to enforce the same policy before file content
+is read. Policy payloads contain ordered `sources`; each source has
+`scope_type`, optional `scope_id`, optional `label`, and a `policy` object. The
+policy object supports `allow`/`allowlist`/`whitelist` and
+`deny`/`denylist`/`blacklist` rules for `connectors`, `providers`,
+`external_ids`, `external_paths`, and `external_urls`. Deny rules win across the
+hierarchy; allow rules narrow access at each source that defines them.
+
+Connector endpoint settings are exposed through governed connector profiles.
+Profiles can be supplied as JSON through
+`GOVOPLAN_FILES_CONNECTOR_PROFILES_JSON`, or from a JSON file path through
+`GOVOPLAN_FILES_CONNECTOR_PROFILES_FILE`. Each profile has an `id`, `provider`,
+`endpoint_url`, governance `scope_type`/`scope_id`, optional `capabilities`, and
+deployment-owned credential references such as `password_env`, `token_env`, or
+`secret_ref`. Environment references require an exact name in the deployment-wide
+`GOVOPLAN_CONNECTOR_SECRET_ENV_ALLOWLIST`; API-managed profiles cannot select
+process environment variables and may use only Files-owned encrypted password or
+token values. API-created `secret_ref` values fail closed until Files has an
+ownership contract that can confirm provider-side deletion. Legacy external
+references are treated as non-owned: deleting a profile or credential detaches
+and audits the reference but never passes it to an arbitrary secret provider.
+Profile and credential deletion immediately clears encrypted values, credential
+identities, deployment references, and private metadata in the same transaction
+as the non-secret audit record; an audit failure rolls the deletion back.
+`GET /api/v1/files/connectors/profiles` returns only profiles visible to the
+current principal (system, tenant, user, group, or accessible campaign scope) and
+redacts secret values and environment variable names. Use the returned
+`policy_sources` with connector policy preflight before importing files.
+`GET /api/v1/files/connectors/providers` exposes provider descriptors for
+Seafile, Nextcloud, WebDAV, SMB, NFS, and local filesystem connectors. The
+descriptor declares implementation status, optional dependencies, permission
+mapping, sync/index strategy, conflict handling, preview behavior, and audit
+events so provider coverage remains visible without forcing every optional
+protocol dependency to be installed.
+`GET /api/v1/files/connectors/profiles/{profile_id}/browse` provides read-only
+connector browsing. Browse entries use a shared `library`/`folder`/`file` shape,
+run profile policy with the `browse` operation, and support Seafile,
+WebDAV/Nextcloud, and SMB when the optional `smb` extra is installed. Seafile
+profiles browse libraries and directories via Seafile's read-only API; profiles
+can still opt into WebDAV browsing by setting `metadata.webdav_endpoint_url` or
+`metadata.browse_protocol` to `webdav`.
+`POST /api/v1/files/connectors/profiles/{profile_id}/import` imports a Seafile
+or WebDAV/Nextcloud/SMB file into managed storage through the same governance,
+conflict handling, source provenance, and connector audit path as direct
+uploads. The Seafile provider uses account-token auth and the native file
+download-link API; Nextcloud and generic WebDAV profiles use authenticated `GET`
+requests against the configured WebDAV endpoint. SMB profiles use
+`smb://server[:port]/share[/path]` endpoints and deployment-owned or encrypted
+stored credentials through `smbprotocol`. Because that SDK cannot accept a
+preconnected socket and may follow DFS referrals to additional hosts, live SMB
+access fails closed in both public-only and private-network deployments. It will
+remain disabled until every initial connection and referral target can be
+policy-validated and pinned.
+
+The S3 browse/import implementation and S3 managed-storage backend currently
+fail closed before creating a `boto3` client. Botocore does not yet use the
+GovOPlaN pinned HTTP transport and may manage redirects itself, so neither an
+explicit endpoint nor SDK endpoint discovery is allowed until both peer pinning
+and redirect revalidation are enforced.
+
+Destructive Files-module retirement applies the same credential lifecycle before
+dropping tables. Every remaining Files-owned encrypted connector secret is
+scrubbed and audited first, while legacy non-owned external references are
+detached and identified as such in the audit record. Retirement does not claim
+or attempt provider-side deletion for references Files cannot prove it owns.
+
+Local connector development assets live in `dev/connectors/`. The compose stack
+boots Nextcloud, Seafile, WebDAV, and SMB endpoints for provider development and
+manual interoperability testing.
+
+Connector and collaboration ownership boundaries are documented in
+`docs/CONNECTOR_BOUNDARY.md` and `docs/DOCUMENT_COLLABORATION_BOUNDARY.md`.
+The role-adaptive user, administration, integration, and operator guide is the
+[Files handbook](docs/FILES_HANDBOOK.md).
+
+ZIP uploads are processed without buffering the whole archive in memory. The API
+spools incoming ZIP request bodies to a bounded temporary file, then extracts
+members with per-file and total extracted-size limits before storing managed
+files.
+
+Bulk rename and transfer APIs are owner-scoped: callers must provide the active
+user or group file space with `owner_type` and `owner_id`. The storage layer
+keeps a named legacy file-only helper for historical callers that lack owner
+context, and regression tests cover its write-access checks.
+
 ## Release packaging
 
 The repository root includes a `package.json` for git-based WebUI installs. It exports the package `@govoplan/files-webui` from `webui/src` so release builds can depend on tagged git refs instead of local `file:` paths.

+# Connector Dev Stack
+
+This directory keeps local Docker Compose assets for GovOPlaN file connector
+development. The stack is intentionally separate from production deployment and
+binds services to localhost high ports.
+
+## Start
+
+```bash
+cd /mnt/DATA/git/govoplan-files/dev/connectors
+cp .env.example .env
+mkdir -p data/smb data/webdav
+docker compose up -d nextcloud nextcloud-db webdav smb minio
+docker compose up -d seafile-db seafile-memcached seafile
+```
+
+If the SMB service was already running before a compose change, recreate it so
+the image and share configuration are applied:
+
+```bash
+docker compose rm -sf smb
+docker compose up -d --build smb
+```
+
+Endpoints:
+
+- Nextcloud: `http://127.0.0.1:9081`, WebDAV root
+  `http://127.0.0.1:9081/remote.php/dav/files/admin/`
+- Seafile: `http://127.0.0.1:9082`, WebDAV root
+  `http://127.0.0.1:9082/seafdav/`
+- WebDAV: `http://127.0.0.1:9083`
+- SMB: `smb://127.0.0.1:1445/files`
+- MinIO/S3 API: `http://127.0.0.1:9000`, console
+  `http://127.0.0.1:9001`
+
+The local fixture data under `data/` is ignored by git.
+
+## GovOPlaN Profile Config
+
+Connector profiles are read from `GOVOPLAN_FILES_CONNECTOR_PROFILES_JSON` or
+`GOVOPLAN_FILES_CONNECTOR_PROFILES_FILE`. This deployment-owned configuration
+may reference environment variables only when their exact names are listed in
+`GOVOPLAN_CONNECTOR_SECRET_ENV_ALLOWLIST`; profile API responses expose only the
+credential source and configured state.
+
+Example local profile file:
+
+```json

+```
+
+Start GovOPlaN with:
+
+```bash
+export GOVOPLAN_FILES_CONNECTOR_PROFILES_FILE=/mnt/DATA/git/govoplan-files/dev/connectors/profiles.local.json
+export GOVOPLAN_CONNECTOR_SECRET_ENV_ALLOWLIST=SEAFILE_ADMIN_PASSWORD,NEXTCLOUD_ADMIN_PASSWORD,WEBDAV_PASSWORD,SMB_PASSWORD,MINIO_ROOT_PASSWORD
+export GOVOPLAN_CONNECTOR_ALLOW_PRIVATE_NETWORKS=true
+```
+
+## Smoke Test
+
+Run the connector helper smoke checks from an environment where
+`govoplan-files` and `httpx` are importable:
+
+```bash
+cd /mnt/DATA/git/govoplan-files/dev/connectors
+/mnt/DATA/git/govoplan-core/.venv/bin/python smoke.py
+```
+
+The script reads `.env` from this directory when present and seeds tiny WebDAV,
+Nextcloud, SMB, and MinIO fixtures. WebDAV and Nextcloud are browsed and imported
+through the pinned connector transport. SMB and S3 product access deliberately
+fails closed until their SDK transports support peer pinning, so their fixtures
+are retained for transport development and reported as expected optional skips.
+The `--require-smb` and `--require-s3` switches are useful only while developing
+that transport support and currently make the smoke check fail by design.
+
+SMB smoke checks need the optional Python dependency in the environment running
+the script:
+
+```bash
+/mnt/DATA/git/govoplan-core/.venv/bin/python -m pip install -e /mnt/DATA/git/govoplan-files[smb]
+```
+
+S3 smoke checks need the optional boto3 dependency in the environment running
+the script:
+
+```bash
+/mnt/DATA/git/govoplan-core/.venv/bin/python -m pip install -e /mnt/DATA/git/govoplan-files[s3]
+```
+
+The SMB service is built from `dev/connectors/smb/` so the development share is
+deterministic: one `files` share backed by `data/smb`, with the credentials from
+`.env`.
+
+The SMB image runs as the non-root `govoplan` user with UID/GID `1000` and
+listens on unprivileged container port `1445`. The default host endpoint remains
+`smb://127.0.0.1:1445/files`. `SMB_USER` must stay `govoplan` unless the image is
+rebuilt with a matching user; `SMB_PORT` must be `1024` or higher. `SMB_PASSWORD`
+is applied when the image is built, so rebuild the `smb` service after changing
+it in `.env`.

+# File Connector Boundary
+
+GovOPlaN Files owns the managed-file boundary: frozen blobs, versions, shares,
+campaign attachment evidence, provenance, connector policy, connector profiles,
+and read-only browse/import APIs that turn external files into managed
+GovOPlaN files.
+
+The built-in connector layer is intentionally on-demand. It does not run remote
+indexing, background sync, remote mutation, or upstream permission management.
+Connectors may browse an external source, import one selected file, freeze it as
+a managed file, record provenance, and audit the access.
+
+## Built-In Baseline
+
+The files module may keep small baseline providers when they are needed for
+normal product workflows and can share the same governance model:
+
+- Seafile through the native read/download API
+- Nextcloud through WebDAV
+- generic WebDAV
+- SMB through the optional `smb` extra
+
+These providers are surfaced through connector descriptors at
+`GET /api/v1/files/connectors/providers`. Provider descriptors declare whether
+the provider is implemented, whether its optional dependency is installed, and
+which browse/import behaviors are available.
+
+## Separate Connector Module Candidates
+
+A separate connector module becomes appropriate when integration needs exceed
+on-demand browse/import:
+
+- background indexing or synchronization
+- bidirectional remote mutation
+- long-running transfer workers
+- provider-specific credential lifecycle or OAuth flows
+- DMS/eAkte metadata models, registers, retention, or filing plans
+- S3-compatible object store administration
+- NFS host-mount lifecycle or sidecar coordination
+- provider-specific WebUI administration beyond profile fields
+
+In that model, `govoplan-files` should keep the managed-file import contract,
+policy checks, provenance model, and audit events. A connector module should own
+provider-specific discovery, synchronization, credentials, health checks, and
+any remote write behavior.
+
+## Provider Responsibilities
+
+Every provider must:
+
+- enforce GovOPlaN profile visibility and connector policy before browse/import
+- keep credentials as encrypted values or scoped secret references, never API
+  response values; process-environment references are allowed only in
+  deployment-owned profiles with an exact deployment allowlist
+- import external files into managed storage before they are used in campaigns
+  or workflows
+- preserve source provenance and revision metadata
+- emit connector audit events for imported or accessed files
+- treat remote ACLs as upstream checks, not as a replacement for GovOPlaN policy
+- use a transport that pins every connection to a policy-validated DNS/IP answer
+  and revalidates redirects; SDK transports without that guarantee fail closed
+
+Live SMB access is disabled in all modes until `smbprotocol` initial connections
+and DFS referral targets can be pinned and policy-validated. An explicit IP is
+not sufficient because the server may still issue a referral to another peer.
+Live S3 access is likewise disabled until `boto3`/botocore can be bound to the
+pinned transport, including SDK-managed redirects and endpoint discovery.
+
+## Non-Goals For Files
+
+Files does not own collaborative editing, comments, document review workflows,
+remote lock orchestration, DMS records management, or external system data
+models. Those belong to future document, workflow, DMS, or connector modules and
+should integrate through capabilities and managed-file imports.

+# Connector Spaces
+
+GovOPlaN Files should treat external file shares as two separate product
+objects:
+
+1. A governed connection profile defines a reusable remote endpoint such as a
+   WebDAV server, Nextcloud account, Seafile server, or SMB share. Profiles are
+   administered in settings at system or tenant scope, with the same
+   inheritance and limit semantics used by mail-server profiles.
+2. A governed credential profile defines reusable authentication material for
+   one provider or for any compatible provider. Credentials are administered
+   separately from connection profiles and can carry their own allow/deny
+   policy.
+3. A linked file space binds one concrete remote folder or library path from an
+   allowed profile to a user or group. Linked spaces appear beside "My files"
+   and group file spaces in the files module.
+
+This keeps secrets, endpoint governance, and tenant limits in settings, while
+keeping user/group workspaces and concrete folder choices in the files module.
+
+## Model
+
+Connection profile:
+
+- provider: `seafile`, `nextcloud`, `webdav`, `smb`, or a future provider
+- endpoint URL and optional base path
+- scope: `system` or `tenant` for administered profiles; user/group profiles
+  may be allowed later only when policy explicitly permits them
+- optional credential profile id
+- capabilities: browse, sync, import, optional write when a provider supports it
+- profile-local policy for allow/deny rules
+
+Credential profile:
+
+- provider: a specific provider or any provider
+- scope: `system` or `tenant` for administered credentials
+- credential mode: anonymous, scoped secret reference, or encrypted stored
+  password/token; environment references are reserved for deployment-owned JSON
+  profiles and exact deployment allowlisting
+- username and redacted secret configuration
+- credential-local policy for allow/deny rules
+
+Connector policy:
+
+- system policy is the baseline
+- tenant policy inherits system policy and may narrow it unless system allows
+  lower-level relaxation
+- future user/group policy may narrow tenant policy for self-service links
+- policies can allow or block providers, profile ids, endpoint URLs, external
+  path prefixes, credential ids, credential inheritance, and local linked-space
+  creation
+
+Linked connector space:
+
+- owner type: user or group
+- display name
+- connector profile id
+- remote library id or share id
+- remote root path
+- sync mode: manual initially; background sync is future work
+- read-only flag from provider/policy
+- active/deleted state
+
+The linked space should be addressable as a normal file space in the files UI.
+For the first implementation slice, actions may use the existing connector
+browse/sync APIs and managed file storage. A linked space can therefore browse
+the remote folder and sync selected files into managed storage. Later slices can
+add a native remote listing view or background sync jobs.
+
+## Policy Semantics
+
+Use mail-profile terminology because administrators already see it there:
+
+- must use: lower scopes are restricted to selected profile ids or providers
+- can use: lower scopes may choose from inherited allowed profiles
+- shall not use anything outside: endpoint URLs and path prefixes are enforced
+  by deny/allow rules before browse, import, or sync
+- may create local links: controls whether users/groups can add linked spaces
+  from inherited profiles
+
+Connector policy should provide an explainable effective policy response with
+source path entries: system, tenant, user, group, campaign when applicable.
+
+## Current State
+
+Implemented:
+
+- provider descriptors for Seafile, Nextcloud, WebDAV, and SMB
+- database-backed connector profiles with system and tenant scope
+- database-backed connector credentials with system and tenant scope
+- encrypted stored password/token support for database credentials
+- JSON/environment-defined connector profiles with system, tenant, user, group,
+  and campaign visibility
+- connector allow/deny policy enforcement before browse/import/sync, including
+  provider, connection profile, credential profile, and path checks
+- read-only browse endpoints
+- import and sync into managed files with provenance and revision metadata
+- audit events for connector import, sync, and access
+- settings/admin UI sections for system and tenant file connections and
+  credentials
+- linked connector-space rows owned by users or groups
+- file-space API responses that include linked connector spaces
+- Files UI entry point to create linked connector spaces from a browsed remote
+  profile/folder
+- Files UI sync dialog for choosing a profile, browsing a remote folder, and
+  syncing a selected file into a managed destination folder
+- Files UI connector-space view with provider/read-only/manual-sync state
+- Docker dev stack smoke checks for WebDAV, Nextcloud, and SMB
+
+Missing:
+
+- explicit connector profile policy rows equivalent to mail-profile policies
+- effective connector policy/explain UI equivalent to mail-profile policies
+- edit/manage actions for existing linked connector spaces
+- optional background sync or remote-write semantics
+
+## Implementation Phases
+
+1. Persist governed connector profiles and policies.
+   - `file_connector_profiles` exists for system and tenant profiles.
+   - `file_connector_credentials` exists for system and tenant credentials.
+   - Environment JSON profiles remain bootstrap/compatibility profiles.
+   - Profile and credential CRUD endpoints exist for database-backed records.
+   - Remaining: `file_connector_policies` plus effective policy/explain output.
+
+2. Add linked connector spaces.
+   - `file_connector_spaces` exists with owner user/group, profile id, library
+     id, remote path, display label, sync mode, and active state.
+   - Connector policy is enforced before creating or using a link.
+   - Linked connector spaces are returned from `/api/v1/files/spaces`.
+
+3. Surface linked spaces in the Files UI.
+   - Linked spaces appear beside managed user/group spaces.
+   - The add-space dialog browses an allowed profile and links the current
+     remote folder/library root.
+   - The connector browser/sync flow is reused when a linked space is open.
+   - Remaining: edit/manage actions for existing linked spaces.
+
+4. Add sync orchestration.
+   - Manual sync selected file is already available.
+   - Add folder-level manual sync.
+   - Add optional scheduled/background sync with conflict reporting.
+
+5. Add provider-specific expansion.
+   - OAuth/secret-store credentials.
+   - Remote write and delete only where policy and provider support it.
+   - DMS/eAkte metadata integrations in a separate connector or documents
+     module.

+# Document Collaboration Boundary
+
+GovOPlaN Files is the governed managed-file module. It stores uploaded/imported
+blobs, versions, shares, provenance, ZIP imports/exports, connector imports, and
+campaign attachment evidence. It should stay reliable, auditable, and simple.
+
+Collaborative document behavior should be owned by a future documents module or
+by provider-specific connector modules when the behavior is delegated to systems
+such as Nextcloud, Seafile, Collabora, OnlyOffice, OpenDesk, or DMS/eAkte
+platforms.
+
+## Files Owns
+
+- managed blobs and immutable version evidence
+- owner-scoped user/group file spaces
+- shares and access checks for managed files
+- connector browse/import into managed storage
+- source provenance, source revision, and audit events
+- freeze-before-send campaign attachment behavior
+- previews generated from managed file versions
+
+## Documents Or Connectors Should Own
+
+- co-editing sessions and editor launch URLs
+- comments, suggestions, document tasks, and review state
+- check-in/check-out, remote locks, and lock timeouts
+- semantic document versions beyond blob versions
+- template merge flows and generated-document lifecycle
+- external DMS metadata, filing plans, record categories, and retention classes
+- provider-specific sync state and conflict resolution
+- collaborative presence and notification behavior
+
+## Integration Shape
+
+The documents layer should integrate with files through stable contracts:
+
+- create or import a managed file version for evidence points
+- attach source provenance when a file came from an external editor or DMS
+- ask files for read/download access rather than importing files internals
+- emit workflow/audit events when a collaborative document reaches a governed
+  state such as reviewed, approved, frozen, sent, or archived
+- use connector providers for provider-specific browse/import/write behavior
+
+Files may expose links to a document or connector module, but it should not own
+the collaboration state machine. A collaborative document can produce many
+working states; GovOPlaN Files should persist the governed snapshots that other
+modules can safely use as evidence.
+
+## Practical Rule
+
+If a feature is about storing, sharing, importing, downloading, or freezing a
+file, it belongs in `govoplan-files`. If a feature is about people jointly
+editing, reviewing, locking, commenting on, or routing a document through a
+semantic process, it belongs in a documents/workflow/DMS integration module.

+# GovOPlaN Files Handbook
+
+This handbook describes the Files module as implemented in version `0.1.9`.
+It is the operational source of truth for users, process owners, administrators,
+operators, auditors, and module integrators. Statements about future behavior
+are marked **planned**; an unmarked statement describes the current code.
+
+Files is a governed snapshot store. It owns managed file content, versions,
+logical folders, shares, source provenance, and the evidence that another
+GovOPlaN module used a particular file version. It can browse selected external
+stores read-only and import a frozen copy. It is not a general remote filesystem,
+a document collaboration engine, or a records-management system.

+
+## The service contract
+
+A managed file is a tenant-scoped logical asset with exactly one user or group
+owner, a normalized path, and a current version. The current version points to a
+blob record containing the storage location, SHA-256 checksum, byte size, and
+content type. Current service paths append a version when connector sync finds
+changed content; they do not mutate the previous version record.
+
+Content with the same tenant, SHA-256 checksum, and size can reuse one blob.
+This is storage deduplication and integrity evidence, not proof of authorship or
+source authenticity.
+
+The main domain objects are:
+
+| Object | Meaning | Lifecycle today |
+| --- | --- | --- |
+| File asset | The user-facing file identity, owner, logical path, description, metadata, and current version | Created, organized, shared, and soft-deleted |
+| File version | A numbered snapshot of one asset and its blob | Appended by connector sync when bytes change; retained |
+| File blob | Stored bytes plus checksum, size, backend, key, reference count, and optional retention timestamp | Reused within a tenant; no automated garbage collection |
+| Folder | An explicit logical path in a user or group space | Created, moved/renamed through organize operations, and soft-deleted |
+| Share | A grant from an asset to a user, group, tenant, or campaign with `read`, `write`, or `manage` permission | Created or updated; no public revocation endpoint yet |
+| Connector profile | A governed external endpoint, scope, optional credential link, policy, and descriptive capabilities | Created, updated, disabled, or credential-scrubbed on deletion |
+| Connector credential | Reusable authentication material, optionally limited to a provider and scope | Encrypted when database-managed; immediately scrubbed on deletion |
+| Connector policy | Allow and deny rules inherited from system through tenant to one leaf scope | Evaluated before configuration and connector use |
+| Connector space | A read-only, manually synchronized remote folder/library linked to a user or group space | Created, updated, disabled, and soft-deleted |
+| Campaign attachment use | Evidence connecting a campaign job or entry to an exact asset, version, blob, checksum, and stage | Retained for campaign execution evidence |
+
+## User tasks
+
+The Files page is available at `/files`. Actions appear only when the current
+principal has the required permission and resource access.
+
+The configured Help Center projects these sections as independently authorized
+tasks, so upload, ZIP import, organization, download, sharing, and deletion do
+not disappear merely because an unrelated permission is absent. It states the
+deployment's actual upload limits. External import appears as a task only when
+the actor has the required permissions and at least one actor-visible profile
+is eligible for the current fail-closed browse/import path; endpoint, path, and
+item policy are still enforced when the operation runs.
+
+### Choose a space
+
+Every file user sees **My files**. Group spaces are added for active groups of
+which the user is a member. The space list also exposes every tenant group to a
+Files administrator; governed API operations can administer other tenant-owned
+Files resources when their owner is specified. Linked connector spaces appear
+beside managed spaces when they are active and visible to the user.
+
+A connector space is intentionally read-only. It is a view of an approved
+remote location and a starting point for importing or synchronizing selected
+files into managed storage; it is not a mounted write-through filesystem.
+
+### Upload files
+
+The managed-space UI supports upload and drag-and-drop. A caller chooses the
+user or group owner and destination folder. The normal per-file deployment
+limit defaults to 50 MiB through `FILE_UPLOAD_MAX_BYTES`.
+
+When a target path already exists, the operation must use one of these conflict
+strategies:
+
+- `reject` stops instead of silently replacing content;
+- `rename` selects the next available `copy` name;
+- `overwrite` soft-deletes the conflicting asset and creates the new asset;
+- an item-specific conflict resolution can also `skip` that item.
+
+An ordinary upload does not append a new version to an existing asset. The
+`overwrite` strategy retires the old asset at that path. Version-preserving
+updates currently belong to connector sync.
+
+### Upload and unpack ZIP files
+
+The UI can unpack a ZIP upload. The request body is spooled to a bounded
+temporary file rather than buffered wholly in memory. The defaults are:
+
+- 250 MiB compressed request and total extracted data;
+- 50 MiB per extracted member;
+- 1,000 non-directory members;
+- encrypted archives are rejected;
+- member paths are normalized and `..` traversal is rejected;
+- the actual bytes read are counted, not only the ZIP header declarations.
+
+The byte limits use `FILE_UPLOAD_ZIP_MAX_BYTES` and
+`FILE_UPLOAD_MAX_BYTES`. The 1,000-member limit is currently fixed in the
+extraction service.
+
+### Organize files and folders
+
+With `files:file:organize`, a user can:
+
+- create logical folders;
+- rename one selection directly;
+- preview and apply bulk prefix, suffix, or replacement renames;
+- move or copy files and folder trees between accessible user/group spaces;
+- resolve target conflicts by rejecting, renaming, overwriting, or skipping;
+- use drag-and-drop for move operations in the file explorer.
+
+Copies create new assets and versions while reusing the immutable blob bytes.
+Moves keep the asset identity and change its owner/path. All source and target
+owners are validated; knowing an identifier does not bypass space membership.
+
+Recursive folder deletion is the default. It soft-deletes the selected folder,
+its child folders, and files below it. A non-recursive delete fails when the
+folder is not empty.
+
+### Find and download files
+
+Files can list by owner and path, use cursor pagination, and consume incremental
+changes through a watermark. The UI supports path/name pattern search and
+sorting. The pattern API can resolve campaign-style wildcard selections and can
+return unmatched files.
+
+A user with download permission and resource access can download one current
+version or create a ZIP archive from a selection. Downloads use an attachment
+content disposition. The archive is generated in a temporary file and removed
+after the response completes.
+
+There is no dedicated content-preview service in the Files API today. File
+responses expose content type, size, checksum, and current version metadata.
+
+### Share files
+
+The API can grant or update a share for a user, group, the tenant, or a campaign.
+The supported permissions are `read`, `write`, and `manage`. Ownership remains
+unchanged. A write operation accepts a `write` or `manage` share; read/download
+accepts any of the three.
+
+The current Files page shows campaign linkage but does not offer a general
+user/group share editor. The API also has no share-revocation route yet. Treat
+share revocation and a complete share-management UI as planned work.
+
+### Browse and import an external file
+
+With a visible connector profile, a user can browse the allowed remote path,
+select one file, and import it into an accessible managed space. The imported
+asset records the connector, provider, remote identity/path/URL, selected remote
+metadata, and source revision when supplied by the provider.
+
+Manual sync looks for an existing managed asset with the same source identity
+inside the chosen owner space:
+
+- no match creates a managed asset;
+- identical checksum and size updates provenance and returns `unchanged`;
+- changed bytes append a version and return `updated`.
+
+Browse, import, and sync never write, rename, or delete the remote source.
+
+## Process perspective
+
+### Managed ingestion
+
+The managed-file flow is:
+
+1. Core authenticates the principal and evaluates the operation permission.
+2. Files validates the tenant, owner, group membership, or applicable share.
+3. Files normalizes the logical path and resolves conflicts explicitly.
+4. Upload or connector response limits are enforced before content is retained.
+5. Files calculates SHA-256 and stores or reuses a tenant blob.
+6. Files creates the asset/version records and optional campaign share.
+7. The database transaction commits and emits change-sequence entries.
+8. Connector-originated operations also emit their connector audit evidence.
+
+Blob storage is not part of the database transaction. An object may therefore
+be left without committed metadata after a process or database failure. No
+automatic orphan reconciliation exists yet; operators must account for this in
+integrity checks and retention plans.
+
+### Governed connector import
+
+The connector flow separates four concerns:
+
+1. An administrator defines reusable credential material.
+2. An administrator defines a scoped endpoint profile that may reference that
+   credential.
+3. System, tenant, and leaf policy sources narrow the allowed profile,
+   credential, provider, URL, and remote path.
+4. A user optionally links an allowed remote root as a user/group connector
+   space, then browses and imports selected content.
+
+Before each network operation, Files checks profile visibility, connector
+policy, endpoint safety, transport support, and response size. A successful
+import becomes an independent managed snapshot. Later source changes have no
+effect until an explicit sync.
+
+### Campaign attachment evidence
+
+When Campaign uses Files, the integration follows a freeze-before-send model:
+
+1. The campaign refers to managed user/group sources and attachment patterns.
+2. Files verifies access and resolves matching managed assets.
+3. A prepared campaign snapshot records the exact asset, version, blob,
+   checksum, size, relative path, and source provenance.
+4. Files materializes those bytes for the campaign build without exposing its
+   database models to Campaign.
+5. Campaign job/entry use is recorded and later marked as sent.
+
+Changing the current file after preparation does not change the version already
+recorded as campaign evidence. A file response is marked `audit_relevant` once
+the asset has a sent campaign attachment-use record.
+
+### Process ownership
+
+| Concern | Owner |
+| --- | --- |
+| Authentication, tenants, RBAC evaluation, audit service, change sequence, settings, and module lifecycle | GovOPlaN Core |
+| Managed assets, blobs, versions, folders, shares, connector baseline, provenance, and campaign attachment evidence | Files |
+| Campaign definition, recipient data, message build/send state, and delivery policy | Campaign |
+| Remote ACLs, remote source content, and upstream revision semantics | The external provider |
+| Storage durability, egress policy, master key, secret environment, backup, and recovery | Deployment operator |
+| Collaborative editing, comments, review, locks, and semantic document workflows | A future Documents/workflow/provider module |
+
+## Ownership and access
+
+Files applies both permission checks and resource checks. A broad operation
+permission alone does not make another user's file visible.
+
+### Resource access
+
+- A user owns their personal space.
+- A group member can use the group's file space.
+- A Files administrator can access all Files resources in the active tenant.
+- A file share can grant read or write access to a user, group, or the tenant.
+- Campaign shares are resolved only in a verified campaign context and do not
+  become ordinary user shares.
+- Folders are owned by a user or group; they are not independently shared.
+- Soft-deleted resources are excluded from normal access and listing.
+- Tenant identifiers are checked on every managed object lookup.
+
+The `files.access` capability can explain why a principal has access: resource,
+owner, administrator scope, or active share. It also explains virtual folders
+that exist through child assets even when there is no explicit folder row.
+
+Deleting an organization/access group is vetoed while it owns Files assets,
+folders, connector spaces, or is the target of file shares. Reassign or remove
+those relationships first.
+
+### Operation permissions
+
+| Permission | Allows |
+| --- | --- |
+| `files:file:read` | List and inspect accessible files, folders, spaces, and visible connectors |
+| `files:file:download` | Download an accessible current version or ZIP archive |
+| `files:file:upload` | Upload managed assets and import/sync selected connector files |
+| `files:file:organize` | Create folders, rename, move/copy, and manage linked connector spaces |
+| `files:file:share` | Create or update file shares |
+| `files:file:delete` | Soft-delete accessible writable files and folders |
+| `files:file:admin` | Administer all Files spaces and connector settings in the active tenant |
+
+The `file_manager` role template grants all normal file operations except
+`files:file:admin`. The `file_viewer` template grants read and download.
+System and tenant settings permissions can also authorize the corresponding
+connector administration endpoints.
+
+## Administration and policy
+
+### Profiles, credentials, policies, and spaces
+
+Keep these definitions separate:
+
+- a **credential** holds reusable authentication material and may be restricted
+  to a provider;
+- a **profile** holds the endpoint, scope, base path, credential reference,
+  local policy, and descriptive operation capabilities;
+- a **policy** restricts what a scope may configure or use;
+- a **connector space** links one approved profile/library/path to one user or
+  group and always uses manual, read-only synchronization today.
+
+Profile capability values such as `browse`, `import`, and `sync` are stored and
+returned, but they are descriptive today. Provider implementation and policy
+checks enforce actual availability; do not use the capability list as the sole
+security control.
+
+Profiles, credentials, and policies support `system`, `tenant`, `user`,
+`group`, and `campaign` scopes. A normal user sees system and active-tenant
+profiles plus leaf profiles that match the user, one of their groups, or an
+accessible campaign. Disabled definitions are visible only through authorized
+administrative reads.
+
+### Policy evaluation
+
+For a leaf scope, the effective source chain is:
+
+```text
+system -> tenant -> user | group | campaign
+```
+
+Policy fields are:
+
+- connector/profile IDs;
+- credential IDs;
+- providers;
+- external IDs;
+- external path prefixes or glob patterns;
+- external URL glob patterns.
+
+Rules use `allow` and `deny` objects. Legacy synonyms `allowlist`, `whitelist`,
+`denylist`, and `blacklist` are normalized. A matching deny at any source wins.
+Every allow field defined by a source must match, so lower sources can narrow an
+inherited set. The effective-policy response includes the contributing source
+path and applied fields for explanation.
+
+A parent may set `allow_lower_level_limits` for individual fields such as
+`allow.providers` or `deny.external_paths`. An explicit `false` prevents a lower
+scope from configuring that field. Absence does not lock the field.
+
+Example tenant policy:
+
+```json
+{
+  "policy": {
+    "allow": {
+      "providers": ["webdav", "nextcloud"],
+      "external_urls": ["https://files.example.edu/*"],
+      "external_paths": ["departments/finance"]
+    },
+    "deny": {
+      "external_paths": ["departments/finance/private"]
+    },
+    "allow_lower_level_limits": {
+      "allow.providers": true,
+      "deny.external_paths": true
+    }
+  }
+}
+```
+
+Use `POST /api/v1/files/connector-policy/evaluate` for an explainable preflight.
+The normal profile browse/import/sync routes perform their own policy checks;
+preflight does not replace enforcement.
+
+### Credential rules
+
+Database-created passwords and tokens use Core's Fernet encryption and require
+the deployment `MASTER_KEY_B64` outside development/test/local environments.
+Secret values, environment variable names, and local CA paths are never returned
+in connector profile responses.
+
+API-managed profiles and credentials cannot select process environment
+variables, create an external `secret_ref`, or conceal secret-like values in
+nested metadata. Deployment-owned JSON/file profiles may use `password_env` or
+`token_env` only when the exact environment variable name appears in
+`GOVOPLAN_CONNECTOR_SECRET_ENV_ALLOWLIST`.
+
+Custom CA bundles must be absolute existing files in
+`GOVOPLAN_CONNECTOR_CA_BUNDLE_ALLOWLIST`. TLS verification can be disabled only
+in a development/test runtime.
+
+### Provider status
+
+| Provider | Current status |
+| --- | --- |
+| Seafile | Read-only native API browse/download-link import and manual sync implemented using the pinned HTTP transport; WebDAV opt-in supported |
+| Nextcloud | Read-only WebDAV browse/import/manual sync implemented using the pinned HTTP transport |
+| Generic WebDAV | Read-only browse/import/manual sync implemented using the pinned HTTP transport |
+| SMB | Browse/import code and descriptor implemented, but every live connection fails closed until initial connections and DFS referrals can be policy-validated and pinned |
+| S3 connector | Browse/import code and descriptor implemented, but every live SDK connection fails closed until botocore connections, redirects, and endpoint discovery can be validated and pinned |
+| SharePoint and OneDrive | Provider keys/descriptors reserved; live Microsoft Graph browse/import is planned |
+| NFS and local connector | Described as optional future providers; the local managed-storage backend is a different feature |
+
+Provider descriptors are available from
+`GET /api/v1/files/connectors/providers`. Use their `implemented`, `installed`,
+and support fields for display, but expect a fail-closed transport error where
+the table above says live access is disabled.
+
+## Operator runbook
+
+### Storage configuration
+
+| Setting | Default | Purpose |
+| --- | --- | --- |
+| `FILE_STORAGE_BACKEND` | `local` | Selects `local` or `s3` managed blob storage |
+| `FILE_STORAGE_LOCAL_ROOT` | `runtime/files` | Primary local write/read root |
+| `FILE_STORAGE_LOCAL_FALLBACK_ROOTS` | empty | Comma-separated older read-only roots checked after the primary root |
+| `FILE_STORAGE_S3_ENDPOINT_URL` and related `FILE_STORAGE_S3_*` values | deployment-specific | S3-compatible endpoint, region, credentials, and bucket |
+| `FILE_UPLOAD_MAX_BYTES` | 50 MiB | Direct-upload and ZIP-member maximum |
+| `FILE_UPLOAD_ZIP_MAX_BYTES` | 250 MiB | ZIP request and extracted-total maximum |
+| `MASTER_KEY_B64` | development fallback only | Encrypts database-managed connector secrets |
+
+The local backend is the operational baseline. It resolves every storage key
+under the configured root and rejects escape attempts. Fallback roots support a
+controlled storage-root migration: new writes go to the primary root while
+reads can still find older objects.
+
+The S3 managed-storage adapter currently fails closed before creating a boto3
+client because the SDK cannot yet guarantee connection-time DNS/IP pinning and
+redirect revalidation. Do not select `FILE_STORAGE_BACKEND=s3` for a live Files
+deployment until that boundary is implemented and the status above changes.
+
+Multiple API replicas require the same durable blob namespace. Separate local
+container filesystems will produce incomplete reads. Until a pinned shared
+object-storage transport is available, use one durable shared mount or constrain
+Files traffic to a deployment topology that preserves one consistent local
+root.
+
+### Connector egress
+
+Connector access to private networks is a deployment-wide decision:
+
+```text
+GOVOPLAN_CONNECTOR_ALLOW_PRIVATE_NETWORKS=true|false
+```
+
+Production-like configuration validation requires an explicit value. Public-only
+mode rejects any hostname whose DNS answers include a non-public address.
+Private-enabled mode still rejects link-local, multicast, unspecified, and
+limited-broadcast addresses.
+
+The built-in HTTP transport:
+
+- resolves and validates every connection attempt;
+- connects the socket to the exact approved address while retaining the
+  original hostname for HTTP Host, TLS SNI, and certificate verification;
+- does not inherit proxy settings;
+- refuses redirects instead of following a new peer implicitly;
+- bounds structured responses to 16 MiB and file transfers to 512 MiB by
+  default.
+
+Override the connector response limits with
+`GOVOPLAN_CONNECTOR_MAX_STRUCTURED_RESPONSE_BYTES` and
+`GOVOPLAN_CONNECTOR_MAX_FILE_TRANSFER_BYTES`. The smaller applicable limit wins
+when an import is also subject to `FILE_UPLOAD_MAX_BYTES`.
+
+Never work around a pinning failure by adding a raw IP, disabling TLS, or
+enabling private networks. SMB may redirect through DFS, and S3 SDKs may perform
+their own redirects or endpoint discovery; both remain disabled even for an IP
+literal until every connection peer can be governed.
+
+### Backup and restore
+
+The database and blob namespace are one logical backup set. A usable backup must
+include:
+
+- Files database rows, including asset/version/blob relationships, shares,
+  connector settings, and campaign attachment-use evidence;
+- every object below `FILE_STORAGE_LOCAL_ROOT` and any still-used fallback root;
+- the exact `MASTER_KEY_B64` needed to decrypt retained connector credentials;
+- deployment-owned connector profile files, referenced CA bundles, and secret
+  environment configuration where those definitions are in use.
+
+There is no Files backup/restore API and no automated blob integrity or orphan
+reconciliation job. Use a write quiesce or coordinated snapshots so database
+references and objects represent the same recovery point.
+
+After restore:
+
+1. Verify the active tenant and module migration state.
+2. Verify the storage backend and roots before allowing writes.
+3. Verify that the original master key is available before testing connectors.
+4. Download representative files and compare bytes with their recorded SHA-256.
+5. Test one authorized and one unauthorized owner/share path.
+6. Test a permitted pinned HTTP connector, if connectors are configured.
+7. Review audit and change-sequence continuity around the recovery point.
+
+An inconsistent restore should fail closed for missing objects or undecryptable
+credentials. Do not repair it by deleting evidence rows without an approved,
+audited data-recovery decision.
+
+### Disable, uninstall, and retire
+
+Disabling a module preserves its persistent data. Ordinary uninstall is guarded
+while Files tables contain persistent rows.
+
+Destructive retirement is separate and irreversible at the application level.
+The installer records a database snapshot, then Files scrubs and audits
+remaining encrypted connector material before its database tables are dropped.
+Legacy external secret references are detached and identified as non-owned;
+Files never calls a provider delete operation for them.
+
+The retirement executor drops database tables but does not delete corresponding
+objects from the configured blob backend. Operators must include those orphaned
+objects in the approved retention/destruction plan. Validate the installer
+snapshot and independent blob backup before retirement.
+
+### Operational signals
+
+Use these symptoms as routing hints:
+
+| Symptom | Likely boundary |
+| --- | --- |
+| `Stored object does not exist` | Database/blob restore mismatch, wrong root, or missing shared storage |
+| `Stored secret cannot be decrypted` | Wrong or rotated `MASTER_KEY_B64` |
+| Private/non-public endpoint blocked | Deployment-wide egress policy is public-only or DNS returned a forbidden answer |
+| SDK cannot pin redirects/referrals | Expected fail-closed S3/SMB boundary, not a transient connector outage |
+| Connector response exceeds limit | Remote payload exceeds connector or upload limit |
+| Profile is not visible | Scope, disabled state, campaign access, or policy mismatch |
+| Group removal is vetoed | The group still owns a file/folder/connector space or is a share target |
+
+## Capabilities and integration
+
+Other modules must integrate through Core contracts, Files capabilities, or the
+public HTTP API. They must not import Files ORM models or storage helpers.
+
+### Provided capabilities
+
+| Capability | Purpose |
+| --- | --- |
+| `files.access` (`0.1.6`) | Explain resource access provenance for managed files, explicit folders, and virtual folders |
+| `files.campaign_attachments` (`0.1.6`) | Resolve managed attachment matches, prepare frozen campaign snapshots, annotate built messages, share assets with a campaign, and record/mark exact attachment use |
+
+Files requires Core principal resolution and permission evaluation. Campaign is
+an optional dependency; when installed, Files consumes the optional
+`campaigns.access` interface to verify campaign existence and access. Missing
+optional Campaign support fails explicitly rather than bypassing the check.
+
+### API families
+
+All routes below are under `/api/v1/files`.
+
+| Area | Routes |
+| --- | --- |
+| Spaces and content | `GET /spaces`, `GET /`, `GET /folders`, `GET /delta` |
+| Upload and folders | `POST /upload`, `POST /upload-zip`, `POST /folders`, `POST /folders/delete` |
+| File access | `GET /{file_id}`, `GET /{file_id}/download`, `DELETE /{file_id}`, `POST /bulk-delete` |
+| Organization | `POST /bulk-rename`, `POST /transfer`, `POST /archive.zip`, `POST /resolve-patterns` |
+| Sharing | `POST /{file_id}/shares`, `POST /bulk-shares` |
+| Connector spaces | `GET/POST /connector-spaces`, `PATCH/DELETE /connector-spaces/{space_id}` |
+| Connector catalog/discovery | `GET /connectors/providers`, `POST /connectors/discover` |
+| Connector profiles | `GET/POST /connectors/profiles`, `GET/PATCH/DELETE /connectors/profiles/{profile_id}` |
+| Browse/import/sync | `GET /connectors/profiles/{profile_id}/browse`, `POST /connectors/profiles/{profile_id}/import`, `POST /connectors/profiles/{profile_id}/sync` |
+| Credentials | `GET/POST /connectors/credentials`, `GET/PATCH/DELETE /connectors/credentials/{credential_id}` |
+| Policy | `GET/PUT /connectors/policies/{scope_type}`, `POST /connector-policy/evaluate` |
+| Incremental connector settings | `GET /connectors/settings/delta` |
+
+Consumers should use cursor/watermark contracts instead of assuming an
+unbounded complete list. The default full-list page size is 500 and public page
+sizes are capped at 1,000.
+
+### Integration invariants
+
+An integrating module should:
+
+- ask Files/Core for access rather than trusting a submitted file ID;
+- retain an exact version/blob/checksum at every governed evidence point;
+- import external content before using it in a campaign, report, workflow, or
+  generated document;
+- preserve Files provenance when producing a derived managed snapshot;
+- treat source provenance as captured context, not cryptographic attestation;
+- avoid writing remote providers through the baseline connector layer;
+- define a separate capability when it needs behavior beyond managed snapshots;
+- tolerate Files being absent when the integration is declared optional.
+
+Future Postbox, Templates/Reports, BI, Documents, DMS, and workflow modules
+should keep their own domain state and use Files for governed input/output
+snapshots. Long-running provider sync, OAuth, remote mutation, and
+provider-specific health belong in connector modules rather than expanding the
+Files baseline indiscriminately.
+
+## Security, provenance, audit, deletion, and retention
+
+### Security controls implemented
+
+- Core authentication, tenant scoping, CSRF/API handling, and RBAC protect the
+  public routes.
+- Owner and share checks protect individual resources after operation-scope
+  checks.
+- Logical paths reject traversal and storage keys cannot escape the local root.
+- Upload, ZIP extraction, connector response, and S3 stream code use bounded
+  reads; encrypted ZIP archives are rejected.
+- Connector HTTP sockets use connection-time DNS/IP validation and pinning,
+  redirects are refused, and unsafe SDK transports fail before client creation.
+- Database-managed connector passwords/tokens are encrypted; responses redact
+  secrets and deployment references.
+- API metadata is recursively checked for secret-like values.
+- Downloads use sanitized attachment filenames.
+- SHA-256 and byte size are recorded for every blob/version.
+
+The module does **not** currently provide malware scanning, content disarm and
+reconstruction, a file-type allowlist, per-user quota, at-rest encryption for
+local blob bytes, or a dedicated preview sandbox. Deployments that require
+these controls must supply them outside Files until explicit module contracts
+exist.
+
+### Provenance
+
+Connector-originated assets can retain:
+
+- source type;
+- connector/profile ID and provider;
+- external ID, path, and URL;
+- revision and revision label;
+- observation/import timestamps when supplied;
+- selected provider metadata.
+
+The normalized provenance and source revision are returned in file responses,
+carried into campaign attachment matches, and included in connector audit
+events. External metadata is provider/user input and is not a digital signature.
+
+### Audit and change evidence
+
+Files records canonical audit events for:
+
+- connector discovery attempts, before the attempted external I/O;
+- connector imports and manual syncs;
+- download/archive access to connector-originated managed files;
+- immediate connector profile and credential deletion/scrubbing;
+- credential scrubbing during destructive module retirement.
+
+Connector audit details include the managed asset/version/blob, checksum, size,
+operation, source revision, and provenance where applicable. Deletion audit
+details name secret/reference kinds but never the secret values.
+
+Assets, folders, shares, profiles, credentials, policies, and connector spaces
+also feed Core's incremental change sequence for UI synchronization. A change
+entry is not equivalent to a canonical audit event. Ordinary local upload,
+rename, share, and soft-delete operations do not yet all emit dedicated Files
+audit events.
+
+Campaign attachment-use records provide separate domain evidence for an exact
+file version used in campaign preparation and delivery.
+
+### Deletion semantics
+
+The word "delete" has different meanings by object type:
+
+| Object | Current delete behavior |
+| --- | --- |
+| File asset | Sets `deleted_at`; content, versions, blob references, and campaign evidence remain |
+| Folder | Sets `deleted_at`; recursive deletion also soft-deletes descendants |
+| Connector space | Sets `deleted_at` and disables the space |
+| Connector credential | Immediately disables the tombstone and clears username, encrypted password/token, environment references, legacy external reference, mode, and private metadata; dependent profiles are disabled and detached |
+| Connector profile | Immediately disables the tombstone and clears credential links/material/references and private metadata |
+| Legacy `secret_ref` | Detached and audited as an unowned external reference; no provider deletion is attempted or claimed |
+| Module retirement | Scrubs/audits credential material, then drops Files database tables; blob-backend cleanup is an operator responsibility |
+
+Credential/profile scrubbing and its audit event use the same database
+transaction. If audit creation fails, the deletion rolls back. Repeating a
+delete against an already scrubbed tombstone does not recreate secret evidence.
+
+### Retention boundary
+
+File versions and blobs are effectively retained indefinitely today. Although a
+blob has `ref_count` and `retained_until` fields, no complete retention-policy,
+legal-hold, hard-purge, or garbage-collection service enforces them. There is
+also no supported user restore endpoint for soft-deleted assets/folders and no
+automated orphan-object reconciliation.
+
+Do not promise erasure, timed retention, legal hold, or self-service recovery
+from the current soft-delete behavior. Those require an explicit, auditable
+retention/purge design that preserves campaign and other evidence references.
+
+## Acceptance scenarios
+
+These scenarios describe expected behavior at the current boundary.
+
+### Personal and group ownership
+
+Given Alice has `files:file:upload` and belongs to Finance, when she uploads to
+her personal or Finance space, then the asset has the selected owner and tenant.
+Given Bob is outside Finance and has no share or Files admin permission, the
+same asset ID must not make the asset readable to Bob.
+
+### Safe ZIP import
+
+Given a ZIP member contains `../../secret.txt`, is encrypted, exceeds 50 MiB,
+or pushes actual extracted bytes above 250 MiB, unpacking must fail without a
+committed managed asset. A valid archive must preserve normalized relative paths
+below the chosen logical folder.
+
+### Explicit conflicts
+
+Given a target path already exists, `reject` must leave it unchanged, `rename`
+must choose a non-conflicting path, and `overwrite` must soft-delete the old
+asset before creating the replacement. A per-item `skip` must not create that
+item.
+
+### Policy-denied connector
+
+Given the tenant permits WebDAV only below `departments/finance` and denies its
+`private` child, a browse/import/sync request below the denied child must return
+an explainable policy denial. Directly invoking the import endpoint must not
+bypass the same rule.
+
+### Pinned connector transport
+
+Given public-only mode and DNS returns any private address, the connection must
+be rejected before a socket opens. Given private mode, the HTTP connection must
+still use the validated address and reject redirects. SMB and S3 must fail
+before their SDK clients connect until all SDK-managed peers can be pinned.
+
+### Imported evidence and sync
+
+Given a permitted WebDAV file is imported, its managed response and audit event
+must carry source identity, revision when available, current version, checksum,
+and size. Re-syncing identical bytes must return `unchanged`; changed bytes must
+create a higher version while preserving the previous version.
+
+### Campaign freeze
+
+Given a campaign snapshot selected version V1, when the managed asset later
+advances to V2, the prepared/sent attachment-use evidence must still identify
+V1 and its original blob/checksum.
+
+### Immediate credential deletion
+
+Given a database credential contains an encrypted password and is referenced by
+two profiles, deleting it must scrub the credential, disable/detach both
+profiles, record non-secret audit evidence, and publish connector-setting
+changes in one transaction. If audit creation fails, no part of the deletion
+may commit.
+
+### Recovery
+
+Given a coordinated database/blob backup and the original master key, restoring
+it must allow representative downloads whose bytes match recorded SHA-256
+values. A missing blob or wrong key must surface an error rather than silently
+returning different content or credentials.
+
+## Implemented and planned boundary
+
+| Area | Implemented now | Planned or explicitly outside the current boundary |
+| --- | --- | --- |
+| Managed storage | Local durable-root backend, fallback read roots, tenant blob deduplication, checksums | Operational S3 after pinned SDK transport ([#34](https://git.add-ideas.de/GovOPlaN/govoplan-files/issues/34)); automated integrity/orphan reconciliation ([#36](https://git.add-ideas.de/GovOPlaN/govoplan-files/issues/36)) |
+| Upload | Bounded direct upload, drag-and-drop UI, ZIP spool/extract limits, explicit conflicts | Malware scanning, quotas, type policy, resumable/chunked upload |
+| Organization | Folders, bulk rename preview/apply, move/copy, drag-and-drop, ZIP download, pattern resolution | General file-history UI and user-driven append-version/restore |
+| Sharing | User/group/tenant/campaign grant or permission update through API; campaign linkage display | Share revocation/expiry and complete general share-management UI ([#37](https://git.add-ideas.de/GovOPlaN/govoplan-files/issues/37)) |
+| Deletion/retention | Soft-delete assets/folders/spaces; immediate audited connector-secret scrubbing | File restore API, hard purge, retention policy, legal hold, and blob GC ([#38](https://git.add-ideas.de/GovOPlaN/govoplan-files/issues/38)) |
+| Connector governance | Scoped profiles/credentials/policies, effective source explanation, separate credentials, linked user/group spaces | Provider-owned external secret lifecycle; API `secret_ref` remains rejected |
+| HTTP connectors | Pinned, bounded, no-redirect Seafile and WebDAV/Nextcloud browse/import/manual sync | Background/folder sync, remote mutation, long-running transfer workers |
+| SMB and S3 connectors | Provider descriptors and browse/import logic | Live access only after SDK connections plus DFS referrals/redirects are validated and pinned ([SMB #35](https://git.add-ideas.de/GovOPlaN/govoplan-files/issues/35), [S3 #34](https://git.add-ideas.de/GovOPlaN/govoplan-files/issues/34)) |
+| Other providers | Reserved SharePoint/OneDrive keys and NFS/local descriptors | Graph/OAuth/provider paging, NFS deployment integration, DMS connectors |
+| Connector spaces | User/group link, browse, manual selected-file sync, edit/disable/delete | Background sync, remote writes/deletes, full conflict-reporting jobs |
+| Profile capabilities | Stored and displayed | Enforce capability flags as an independent operation gate |
+| Audit | Connector discovery/import/sync/access and connector deletion; campaign exact-use evidence | Dedicated canonical audit events for every ordinary Files mutation |
+| Preview | File metadata and attachment download | Dedicated safe content-preview service |
+| Campaign | Stable capability-based frozen attachments and sent-use evidence | Campaign-specific process state remains in Campaign |
+| Collaboration | Governed input/output snapshots | Co-editing, comments, review, presence, locks, and semantic document versions belong to Documents/workflow/provider modules |
+
+## Release and change checklist
+
+Before releasing Files:
+
+1. Keep `pyproject.toml`, root `package.json`, WebUI `package.json`, and the
+   module manifest version aligned. Version alignment is a release gate.
+2. Run the Files Python tests and security/static-analysis gates from the
+   GovOPlaN meta repository.
+3. Build/type-check the WebUI through the Core host application.
+4. Verify database migrations on an upgrade copy and a clean database.
+5. Exercise an allowed and denied owner/share path.
+6. Exercise upload, ZIP bounds, conflict handling, download, and soft deletion.
+7. Exercise connector policy explanation and one pinned HTTP provider where
+   configured; verify S3/SMB still fail closed.
+8. Verify credential deletion scrubs dependents and produces audit evidence.
+9. Verify a campaign attachment snapshot still identifies its exact version and
+   checksum after the current file changes.
+10. Update the implemented/planned table whenever a boundary changes.
