+## 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 Campaign internals.
+- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.

 ## Scope
 
 This repository owns the `campaigns` module: campaign authoring, validation, message building, attachment resolution, queue/review/send control, reports, campaign module manifest, and `@govoplan/campaign-webui`.

+Core owns the auth facade, RBAC/capability contracts, database/session
+primitives, CSRF/API helpers, shell layout, and route rendering. Tenancy is an
+optional platform module for tenant administration and tenant resolver behavior.
+Files and mail own their respective storage and transport capabilities.
+When the optional Reporting module is enabled, Campaign contributes its
+recipient-free aggregate delivery report through the versioned Core report
+provider contract. Reporting owns the global `/reports` route. Campaign keeps
+its module-local `/campaigns/reports` view and does not claim the global route
+when Reporting is absent.
+
+Generated EML and printable artifacts are durable execution material, not a
+node-local runtime cache. Campaign stores EML through Core's shared
+object-storage contract under opaque Campaign-owned keys. Templates returns a
+bounded artifact or a Files-managed artifact for printable output. Database job
+rows retain the expected hashes and provenance. Workers resolve and verify the
+frozen evidence before delivery. Build failure compensates objects written
+before database commit. Retention uses a fenced forward-recovery operation and
+independently verifies both artifact absence and the committed locator update;
+partial or unobservable cleanup remains visible in Ops.
+An operator-only, dry-run-first reconciler inventories bounded tenant-prefix
+pages and removes only old objects that remain unreferenced after an active
+build-fence check. Applied runs are idempotent, fenced, audited, and preserve
+database references on every storage failure.

+- `govoplan-files` enables managed attachment selection, frozen file-version evidence, and managed-file usage tracking. Server/API campaigns require this integration for attachments and never resolve caller-supplied local filesystem paths. Legacy file-oriented loading remains available only to explicitly trusted operator/library workflows.
+- `govoplan-mail` owns reusable profiles, encrypted SMTP/IMAP credentials, delivery policy checks, connection tests, and transport execution. Campaign JSON stores only `server.mail_profile_id`; inline transport settings and credentials are rejected. Without Mail, campaigns can still be authored, but profile validation and real delivery are unavailable.
+- `govoplan-dist-lists` expands reusable governed audiences. Campaign freezes the exact list revision, provider evidence, candidates, and explicit per-recipient primary/fallback route into its own version.
+- `govoplan-templates` validates and renders published label, envelope, letter, and list-layout templates for postal or internal-mail delivery. Generated output is hash-bound to its template, inputs, actor, route decisions, and Campaign version.
+- `govoplan-postbox` resolves exact or organization-derived Postbox targets and records provider acceptance and receipt evidence. It remains optional; Mail-only and print-only campaigns do not require it.
+- `govoplan-calendar` renders and mirrors individualized VEVENT invitations through the versioned `calendar.invitations` capability. Campaign freezes one METHOD:REQUEST attachment per recipient during build, creates the Calendar mirror only after delivery acceptance, and reads live RSVP state in bounded report batches. Mail may forward METHOD:REPLY parts from an authorized IMAP source. Calendar absence leaves ordinary Campaign authoring and delivery usable.
+
+Hybrid delivery never treats an opt-in as an implicit duplicate-send instruction. The Campaign author selects one primary route per recipient and may select a supported fallback. A fallback runs only after the first channel rejects before acceptance; accepted or outcome-unknown effects stop cross-channel retry. Printable output is generated once during build, optionally persisted through Files, reviewed with the exact Campaign version, and accepted idempotently per recipient job during delivery.
+
+Recurring schedules have two immutable modes. Manual mode remains the default
+and prepares independent drafts without Mail. Autonomous mode is explicit and
+Mail-only: it seals an already built and explicitly approved execution snapshot,
+rechecks approval, policy, credential/transport revision, live SMTP health,
+recipient and attachment evidence before each occurrence, and submits one
+Mail-owned durable command per frozen message. Occurrence-scoped idempotency is
+allocated before delivery. Accepted and outcome-unknown effects are never
+retried automatically; uncertain or systemic failures pause the schedule,
+notify its accountable operator, and retain non-secret recovery evidence.
+Generated EML retention excludes source versions while an autonomous schedule
+has a remaining occurrence, including while it is paused; once the schedule
+finishes, already accepted Mail commands retain their own encrypted payload and
+evidence under Mail policy.
+
+Public campaign, version, job, and report responses expose business data and
+delivery evidence, but never process-local paths, storage-backend keys, or
+worker claim tokens. Operational troubleshooting uses the dedicated job
+diagnostics endpoint and requires the tenant-level
+`campaigns:diagnostic:read` permission. The campaign sender role receives this
+permission; tenant-wide administrator scopes continue to grant it through the
+standard policy evaluator.
 
 Backend optional behavior is accessed through core-provided capabilities, not direct required imports. WebUI optional behavior uses core module metadata/capabilities so campaign pages can build and run without files or mail WebUI packages installed.
 
+Campaign also provides narrow kernel capabilities so other modules and core
+services can cooperate without importing campaign internals:

+- `campaigns.mailPolicyContext` for campaign-scoped mail policy and owner
+  context

+- `campaigns.retention` for campaign-owned retention cleanup

 ## Release packaging
 
 The repository root includes a `package.json` for git-based WebUI installs. It exports the package `@govoplan/campaign-webui` from `webui/src` so release builds can depend on tagged git refs instead of local `file:` paths. Files and mail WebUI packages remain optional product-composition dependencies supplied by the core host build, not required campaign package dependencies.

+# Campaign SMTP/IMAP Test Bed
+
+This test bed provides dedicated non-production SMTP/IMAP infrastructure for
+campaign delivery checks. It uses GreenMail and must never be configured with
+production recipients or credentials.
+
+## Start
+
+```bash
+cd /mnt/DATA/git/govoplan-campaign/dev/mail-testbed
+cp .env.example .env
+docker compose --env-file .env up -d
+```
+
+Default endpoints:
+
+- SMTP: `127.0.0.1:3025`, plain transport
+- IMAP: `127.0.0.1:3143`, plain transport
+- GreenMail API/UI endpoint: `127.0.0.1:38080`
+
+## Smoke Test
+
+Run the transport smoke from the core virtual environment after installing the
+campaign and mail modules:
+
+```bash
+cd /mnt/DATA/git/govoplan-campaign/dev/mail-testbed
+set -a
+. ./.env
+set +a
+/mnt/DATA/git/govoplan-core/.venv/bin/python run_transport_smoke.py
+```
+
+The smoke sends and appends three messages:
+
+- no attachment
+- one normal attachment
+- one password-protected AES ZIP attachment
+
+It verifies SMTP authentication, IMAP authentication, folder listing, delivery
+to `INBOX`, and append-to-Sent behavior.
+
+If the smoke is started immediately after `docker compose up -d`, GreenMail may
+bind the SMTP/IMAP ports before the services are fully ready. The smoke retries
+login and folder setup for `GOVOPLAN_MAIL_TEST_READY_TIMEOUT_SECONDS`.
+
+## Campaign Acceptance
+
+The transport smoke proves the Mail adapters. The Campaign acceptance runner
+proves the public composition: it creates an isolated temporary Core database,
+creates a Mail-owned encrypted profile through the API, materializes the
+credential-free [`greenmail-delivery`](../../examples/greenmail-delivery/campaign.json)
+fixture with only that profile reference, validates/builds it, sends the exact
+generated EML through Campaign once, appends it once, and cross-checks Campaign
+report/audit state with one unique-subject message in the GreenMail INBOX and
+Sent folders. Provider mailbox verification is not a byte-for-byte comparison
+after provider-side header or storage transformations.
+
+```bash
+cd /mnt/DATA/git/govoplan-campaign/dev/mail-testbed
+set -a
+. ./.env
+set +a
+/mnt/DATA/git/govoplan/.venv/bin/python run_campaign_acceptance.py \
+  --evidence /tmp/govoplan-campaign-greenmail-evidence.json
+```
+
+The default run also uses controlled loopback protocol endpoints to prove that
+an SMTP connection loss before transmission is temporary, an explicit SMTP
+authentication rejection is permanent, a final `451` response after DATA is
+temporary, one accepted and one refused RCPT command is retained as partial
+envelope acceptance, a connection loss after complete DATA is frozen as
+`outcome_unknown`, and an IMAP authentication rejection after SMTP acceptance
+leaves the send accepted while the append fails. A
+second ordinary send must be rejected before another provider effect.
+
+The worker drill queues one job, starts the registered
+`govoplan.campaigns.send_email` task body in a dedicated OS process, waits until
+the controlled endpoint has received complete DATA, terminates that process,
+and starts the same task body in a fresh process. It proves the durable
+`sending`/unfinished-attempt boundary is recovered as `outcome_unknown`
+without a second SMTP connection or DATA transaction. This is a real process
+and task-boundary interruption, but it does not start a Celery daemon, Redis
+broker, or broker redelivery; `celery_broker_redelivery` therefore remains
+`false` in the evidence.
+
+The bounded JSON contains no endpoint, account, address, credential, profile,
+campaign, version, or job identifiers. It records module versions, the fixture
+hash, normalized classifications/counts, the Mail-profile boundary, required
+audit actions, provider mailbox increments, and coverage flags. Runtime version
+declarations identify the exercised composition; they do not claim that the
+sources are clean, tagged, signed, or release-provenanced. The evidence names
+them `declared_module_versions` and keeps `source_artifact_provenance` false;
+exact commit/artifact provenance belongs to the package and release gate.
+
+This runner is restricted to literal loopback IP addresses and the synchronous
+Campaign delivery mode. Hostnames such as `localhost` and every non-loopback
+address fail before profile creation, avoiding a DNS change between validation
+and connection. It is local target-like evidence, not approval of an
+institution's SMTP/IMAP service. The controlled post-DATA, temporary-response,
+partial-refusal, and task-process interruption drills are local effect-level
+proof, not proof of a target provider's behavior or Redis/Celery broker
+redelivery. Use `--success-only` only when testing the success journey without
+the local failure endpoints.
+
+## Redis/Celery Redelivery Acceptance
+
+Run the maintained broker/worker-loss acceptance separately from the GreenMail
+journey:
+
+```bash
+cd /mnt/DATA/git/govoplan-campaign/dev/mail-testbed
+set -a
+. ./.env
+set +a
+/mnt/DATA/git/govoplan/.venv/bin/python run_celery_redelivery_acceptance.py \
+  --evidence /tmp/govoplan-campaign-celery-redelivery-evidence.json
+```
+
+The runner creates a unique Compose project, starts only its loopback-bound,
+AOF-enabled Redis service, creates an isolated temporary GovOPlaN database,
+and starts a real Celery worker subscribed to `send_email`. A controlled SMTP
+server holds the transaction after complete DATA and before the final response.
+The runner kills that solo worker with the task still unacknowledged and starts
+a replacement worker. After the configured Redis visibility timeout, the same Celery task identity must be redelivered.
+The replacement must turn the durable
+unfinished attempt into `outcome_unknown`, acknowledge the task, drain the
+broker queue/unacked records, and leave the SMTP endpoint at exactly one
+connection and one DATA transaction.
+
+Only bounded counts, classifications, and booleans are retained. Worker logs,
+task IDs, database identifiers, endpoints, credentials, and raw diagnostics are
+kept in the temporary runtime and deleted. The evidence proves the local Redis
+transport, real Celery process boundary, runner-supervised replacement, and
+Campaign's duplicate-effect guard. It deliberately keeps production daemon supervision,
+target-provider behavior, and source-artifact provenance false.
+It does not claim that systemd, Kubernetes, another container orchestrator, or
+an institution's Redis/SMTP deployment behaves identically.
+
+The default run requires Docker CLI/Compose/daemon access and permission to
+pull `redis:7-alpine`; the Celery workers execute from the current Python
+environment. The isolated Compose project and volume are removed on exit.
+`GOVOPLAN_CAMPAIGN_TEST_REDIS_VISIBILITY_TIMEOUT_SECONDS` defaults to three
+seconds only to make this destructive local drill finish promptly; it is not a
+production recommendation.
+
+Starting the maintained test bed requires a working Docker CLI, Compose plugin,
+daemon/socket access, and permission to pull `greenmail/standalone:2.1.9`. The
+Campaign runner needs only the already-running loopback endpoints; it neither
+starts Docker nor claims that it did.
+
+## Use With A Campaign
+
+Use the same settings in a campaign mail profile:
+
+- SMTP host `127.0.0.1`, port `3025`, security `plain`
+- IMAP host `127.0.0.1`, port `3143`, security `plain`
+- username and password from `.env`
+- append folder from `GOVOPLAN_MAIL_TEST_SENT_FOLDER`
+
+When changing the mailbox, keep `GOVOPLAN_MAIL_TEST_USER` equal to
+`${GOVOPLAN_MAIL_TEST_LOCAL_PART}@${GOVOPLAN_MAIL_TEST_DOMAIN}` because the
+compose file creates the GreenMail account from local part, password, and
+domain while login uses the full email address.
+
+Then run the controlled sending checklist from
+`docs/CAMPAIGN_DELIVERY_RUNBOOK.md` for no attachment, one attachment, and
+password-protected ZIP campaign variants.

+# Campaign Accessibility Review
+
+The Campaign WebUI uses Core's semantic `Button`, `Dialog`, `DataGrid`, form,
+alert, and segmented-control components. Its page frames use Core `PageLayout`
+and its full-canvas navigation/content shells use `WorkspaceLayout`, so pane
+scrolling, sticky headings, action collapse, narrow-layout behavior, and help
+scope remain platform-owned. Core also owns focus trapping, focus return,
+Escape handling, labels, disabled state, and keyboard behavior for the shared
+primitives.
+
+## Repeatable review matrix
+
+Run this matrix for Campaign overview, wizard, sender and recipients,
+attachments, template editing, review and send, operator queue, and reports:
+
+1. Navigate all actions with Tab and Shift+Tab; focus must remain visible and
+   follow the visual reading order.
+2. Activate buttons and links with Enter, and native buttons with Space.
+3. Open every dialog, verify initial focus remains within it, close with Escape,
+   and verify focus returns to the opener.
+4. Use DataGrid sorting, filtering, pagination, row selection, and action menus
+   without a pointer.
+5. At 200 percent browser zoom and a 320 CSS-pixel viewport, verify that content
+   reflows or scrolls without hiding actions.
+6. With reduced motion enabled, verify that workflow state does not depend on
+   animation.
+7. With a screen reader, verify page headings, field labels, validation errors,
+   workflow states, message navigation, and attachment evidence.
+
+## Automated structural guard
+
+`npm run test:accessibility-contract` rejects non-semantic click handlers,
+unlabelled icon-only buttons in the message preview, and Campaign-local modal
+implementations that bypass Core's `Dialog`. It complements rather than replaces
+browser and assistive-technology testing.
+
+The guard also verifies that Campaign retains narrow-viewport layouts, visible
+keyboard focus for domain-specific controls, and an explicit reduced-motion
+override. Shared dialog focus trapping and restoration are tested in Core;
+Campaign tests verify that overlays continue to use that shared primitive.
+
+## Release evidence
+
+The feature implementation can be closed once the structural contract, shared
+Core component tests, TypeScript graph, and representative responsive overlay
+tests pass. The seven-step matrix above remains a release-candidate checklist:
+it must be repeated for the exact browser, language packages, theme, density,
+and assistive-technology combination being certified. Closing the implementation
+ticket does not make a general WCAG-conformance claim for future releases.
+
+Implementation closure evidence recorded on 2026-08-03 used headless Chromium
+against the configured development system. It covered all 13 Campaign routes at
+1440 CSS pixels, the list, overview, recipients, and review routes at 320 CSS
+pixels, reduced-motion rendering, semantic accessibility-tree snapshots, HTTP
+500/page-error capture, and 42 sampled Tab stops across desktop and narrow
+Review & Send. The run found no unnamed interactive controls, hidden focus,
+page-level horizontal overflow, titlebar overlap, or unhandled runtime errors.
+Representative list, overview, review, and narrow-review screenshots were also
+inspected. This is implementation evidence; release certification still uses
+the complete matrix above with the selected screen reader and browser versions.
+
+## Known boundary
+
+Translation keys may be visible in source because Core resolves them at runtime.
+The review must use a built application with current language packages. WCAG
+conformance is a release-level claim and still requires a bounded manual audit
+of the release candidate.

+# Campaign Access Explanation Coverage
+
+Campaign access explanations are resource-specific evidence. They inherit the
+parent Campaign decision only where the child has no independent grant model,
+and they must identify that inheritance explicitly.
+
+## Implemented
+
+- Campaign
+- Campaign version
+- Campaign delivery job / built message
+- Computed Campaign report, identified by Campaign, version, and report kind
+- Recipient row, identified by `<version UUID>:<job UUID>`
+- Frozen recipient source snapshot, identified by its Campaign-version UUID
+- Campaign attachment binding and version-bound frozen attachment resolution
+- Persisted validation issue, version-bound review decision, and attachment-policy override
+- SMTP, IMAP append, Postbox, and printable-output attempts
+- Message action, message-action attempt, and job reconciliation decision
+- Campaign share and Core-owned Campaign ownership-transfer record
+- Independently user-owned recipient import mapping profile
+- Saved recipient import execution, identified by `<version UUID>:<import UUID>`
+- Persisted validation, build, execution-snapshot, and review evidence, identified
+  by `<version UUID>:<artifact kind>`
+
+All persisted child IDs are random UUIDs. Embedded build/review children use a
+version UUID plus a random job UUID, so callers cannot enumerate a recipient
+index or infer an address. A version mismatch is reported as a stale reference.
+Missing and cross-tenant children use the same non-disclosing not-found
+provenance. Explanations never include recipient addresses, source rows,
+filenames, object locators, transport responses, worker claims, target
+snapshots, diagnostic text, or reconciliation notes.
+
+## Permission matrix
+
+| Evidence | Parent boundary | Further restriction |
+| --- | --- | --- |
+| Recipient row or source snapshot | Campaign read/owner/share | `campaigns:recipient:read` |
+| Attachment binding/resolution, validation, review, override | Campaign read/owner/share | Campaign review and `campaigns:diagnostic:read` |
+| Delivery status | Campaign read/owner/share | `campaigns:report:read` |
+| Transport or worker diagnostics | Campaign read/owner/share | `campaigns:diagnostic:read` |
+| Exported delivery evidence | Campaign read/owner/share | `campaigns:report:export` |
+| Reconciliation decision | Campaign read/owner/share | Campaign reconcile and diagnostic read |
+| Share or ownership transfer | Campaign governance | Campaign share, transfer-participant, group-acceptance, or recovery authority; content access remains a separate decision |
+| Import mapping profile | Independent user owner | `campaigns:recipient:import`; no Campaign share is inherited |
+| Import execution | Campaign read/owner/share | Recipient read and import authority |
+| Persisted protocol artifact | Campaign read/owner/share | Recipient, review, report, diagnostic, or export authority appropriate to the artifact |
+
+Postbox, Mail/IMAP, and printable attempts keep bounded Campaign-owned evidence
+after provider acceptance. Their explanation therefore remains available when
+an optional provider module is later disabled. A missing attempt reports only
+the optional owner and `unavailable_or_hidden`; it does not distinguish absence
+from hidden data.
+
+## Optional and unsupported owner boundaries
+
+Reusable templates and template revisions are independently governed by the
+optional Templates module; Campaign never treats a Campaign share as a template
+grant. Durable export packages are independently governed by the optional
+Reporting module. Asking the Campaign provider to explain either class therefore
+fails closed with `independently_governed_by_optional_module` and
+`unavailable_or_hidden`. The response does not reveal whether the optional
+module is absent, the object does not exist, or the caller cannot see it.
+
+Campaign reports generated on demand remain non-persisted, version-bound
+resources. Their explanation names the report kind and its Campaign/version
+parent, and keeps report read, export, and diagnostic permissions distinct.
+
+Each child explanation must include:
+
+- the child resource identity and current state;
+- the parent Campaign and version where applicable;
+- whether access is inherited, independently granted, or further restricted;
+- effective owner/share/policy provenance;
+- missing-module or unavailable-evidence reasons without leaking the hidden
+  object;
+- a stable resource identifier suitable for audit and support links.
+
+Delivery attempts, review decisions, reports, and exports can contain more
+sensitive evidence than the Campaign summary. Their read and diagnostic/export
+permissions therefore remain independently enforceable even when the parent
+Campaign is readable.
+
+Import explanations include only the stable import identity, source type,
+opaque source identity, source revision, and whether additional provenance was
+recorded. They never return imported rows, filenames, column mappings, or source
+metadata. Mapping-profile explanations expose only non-reversible header
+fingerprints and shape information; headers and mappings remain hidden.

+# Campaign Build Recovery
+
+Campaign build is fenced per tenant and Campaign version. Before rendering or
+writing generated artifacts, Campaign commits a Core recovery operation with
+the canonical source and validation hashes, the runtime fence, and a reserved
+opaque object prefix. A repeated idempotency key can replay only a verified
+successful build; it cannot start a second active build.
+
+Generated EML and bounded print output are written to shared storage and checked
+for exact size and SHA-256 content. Campaign renews the build fence after that
+check and before changing jobs, then commits its jobs and execution snapshot,
+compares the stored object and database manifests, and records verified success.
+A managed Files output makes the operation forward-recoverable because Campaign
+cannot undo a Files-owned artifact; object-only builds use explicit
+compensation.
+
+If the Campaign database transaction fails, Campaign deletes every object it
+recorded and verifies absence before recording recovered state. Failed deletion,
+an unavailable storage check, process loss, or superseded-object cleanup failure
+leaves a recovery-required operation visible in Ops. Do not retry such an
+operation as a normal build. Verify its checkpoint chain and reserved prefix,
+then reconcile it through the owning-module procedure.
+
+## Orphan inventory and cleanup
+
+The operator-only endpoint
+`POST /api/v1/campaigns/operations/artifacts/reconcile` requires
+`system:settings:write`. It never scans outside
+`campaign-artifacts/{tenant_id}/`, and one request reads at most `page_size`
+objects. The default request is a dry run:
+
+```json
+{}
+```
+
+The response reports each eligible key, size, modification time, age, reason,
+page totals, and `next_cursor`. Continue with that cursor to inspect the next
+bounded page. Objects are not eligible when they are referenced by a committed
+EML or print-output row, belong to an actively fenced build, have no trustworthy
+modification time, have an invalid build-key shape, or are younger than the
+grace period. The minimum and default grace period is 24 hours.
+
+Apply an inspected page with a new idempotency key:
+
+```json
+{
+  "apply": true,
+  "idempotency_key": "incident-2026-08-03-page-1",
+  "grace_period_hours": 24,
+  "page_size": 250
+}
+```
+
+An applied run rechecks committed references and active build leases before
+each bounded deletion batch. A Core distributed lease prevents two nodes from
+committing the same tenant cleanup concurrently. Every attempted deletion is
+probed afterward. `recovery_required` means an object was verified to remain;
+`outcome_unknown` means storage could not prove whether the delete took effect.
+Use a new idempotency key to retry after the storage problem is corrected. A
+successful repeated request with the same key returns `already_completed` and
+does not delete again.
+
+Cleanup never clears Campaign database references. Audit and recovery evidence
+records counts and hashed manifests rather than object keys. Exact keys are
+returned only by this privileged endpoint and must stay in restricted incident
+records.
+
+No recovery checkpoint contains message bodies, recipients, credentials, or
+resolved provider secrets. Object keys remain restricted diagnostics rather
+than Campaign business data.
+
+Database rows, `campaign-artifacts/` objects, and the encryption/key service are
+one coordinated backup and recovery boundary. After any partial restore, pause
+delivery, run a dry inventory, reconcile Campaign recovery operations in Ops,
+and verify referenced object hashes before workers resume.

+# Campaign Delivery Runbook
+
+This runbook covers controlled campaign delivery after a campaign version has
+been validated, built, reviewed, and locked.
+
+## Operating Modes
+
+- Local direct send: `CELERY_ENABLED=false`. **Send now** is available only for
+  exact built runs within the effective synchronous limit. It preflights the
+  complete batch before the first SMTP effect.
+- Worker send: `CELERY_ENABLED=true` with Redis/Celery workers running. Queueing
+  publishes durable delivery tasks, and Review and send polls their persisted
+  summary counters even after the initiating request has returned.
+- Mock send: use only for development review. It does not prove real SMTP/IMAP
+  credentials or server policy.
+
+## Before First Live Use
+
+- Use dedicated non-production SMTP/IMAP credentials.
+- Store and test those credentials in a Mail-module profile. Campaign must
+  contain only the selected `server.mail_profile_id` reference.
+- Start the repository test bed in `dev/mail-testbed/` when a local
+  production-like SMTP/IMAP server is sufficient.
+- Use a dedicated mailbox/folder for append-to-Sent tests.
+- Confirm policy allows the SMTP host, envelope sender, recipients, and optional
+  IMAP append target.
+- Run one campaign each for no attachment, one attachment, and password-protected
+  ZIP before using production recipients.
+- Keep the report page open during tests; it is the operational source of truth
+  for attempts, outcomes, and reconciliation.
+- Confirm the effective Send now recipient-job limit. The safe default is 25;
+  use Queue for workers for ordinary batches or any run above that limit.
+
+## Deliverability Preflight
+
+Before the first live send for a sender domain or mail-server profile:
+
+- Confirm the selected SMTP identity matches the visible From/envelope sender
+  policy.
+- Confirm SPF, DKIM, and DMARC are handled by the sending infrastructure or
+  documented as out of scope for the selected test environment.
+- Confirm rate limits are explicitly set for the expected provider and recipient
+  volume.
+- Confirm bounce/reply/notification addresses are monitored by an operational
+  mailbox or intentionally disabled.
+- Confirm large attachments and password-protected ZIPs are acceptable for the
+  recipient systems.
+- Confirm owner transfer or policy changes force profile reselection and
+  revalidation before live delivery.
+
+## Queue And Send
+
+1. Validate the version with file checks enabled.
+2. Build the version and inspect all blocking review items.
+3. Queue only after the selected version is the intended immutable execution
+   version. Select **Queue for workers**, then verify the committed and
+   published counts.
+4. Use **Send now** only if the exact eligible count is non-zero and at or below
+   the effective deployment/tenant limit shown on the page.
+5. In worker mode, verify queue counters move from queued/claimed/sending to a
+   terminal SMTP state.
+6. If a synchronous request is used, keep Review and send open: it polls the
+   durable counters while the request runs. A rejection occurs before SMTP and
+   directs oversized runs to workers.
+7. Review the SMTP batch line. `ready` means DNS/connectivity/TLS/auth preflight
+   succeeded. Connection and reconnect counts explain reuse. `paused` means a
+   systemic transport failure stopped the remaining jobs before their SMTP
+   effect; test/correct the Mail profile and explicitly resume the queue.
+
+## Outcome Handling
+
+Each real Campaign job delivery is represented by a Core recovery-ledger
+operation before the worker claims the job or invokes Mail, Postbox, or print.
+Synchronous batches use the same boundary after their batch-wide preflight.
+Explicit test/resend actions and post-acceptance IMAP appends use separate
+action-fenced operations. Operations store only opaque IDs, digests, channel
+policy, and bounded status evidence. A verified acceptance becomes
+`succeeded`, a definitive pre-effect or provider rejection becomes `rejected`,
+and uncertain or stranded effects remain `outcome_unknown` or
+`recovery_required` in Ops. Campaign jobs, message actions, and channel-attempt
+records remain the business source of truth.
+
+For SMTP and Sent-folder APPEND, Campaign also passes the stable job/action and
+attempt identifier into Mail. Mail establishes its own provider-bound recovery
+fence after profile authorization and policy checks but before network I/O.
+This nested ownership is intentional: Campaign proves its business transition,
+while Mail proves the transport effect. Neither layer replays a completed or
+unknown provider attempt merely to repair the other layer's state.
+
+- `smtp_accepted`: Do not retry. If IMAP append is enabled and pending, run or
+  enqueue the append action.
+- `failed_temporary`: Retry explicitly after checking the error and retry count.
+- `failed_permanent`: Retry only if the operator has corrected the root cause and
+  intentionally includes permanent failures.
+- `paused` after a systemic SMTP failure: do not resume until the shared Mail
+  profile passes its connection test. Authentication, sender rejection, and
+  unavailable connectivity affect the batch rather than one recipient.
+- `outcome_unknown`: Do not retry directly. Check SMTP logs, mailbox evidence, or
+  provider control panels, then reconcile as accepted or not sent.
+- `claimed` or `sending` that does not progress: treat as a worker interruption.
+  Re-run worker handling or reconcile if SMTP may already have accepted the
+  message.
+- IMAP `appending`: A worker owns the durable append claim. Do not start a
+  second append; if the worker cannot finish, reconcile only after checking the
+  mailbox.
+- IMAP `outcome_unknown`: Never append automatically. An operator with
+  `campaigns:campaign:reconcile` must record an evidence note and resolve it as
+  `imap_appended` or `imap_not_appended`. Only the latter becomes explicitly
+  retryable.
+
+## Reconciliation
+
+- Choose "Accepted" only with external evidence that SMTP accepted the message.
+  The job becomes protected from retry and may proceed to IMAP append.
+- Choose "Not sent" only when SMTP did not accept the message. The job becomes a
+  temporary failure and can be selected by explicit retry.
+- Add a note that identifies the evidence used, for example SMTP log line,
+  provider message ID, or operator ticket.
+
+## Fault Injection Checklist
+
+Use mock infrastructure first, then repeat against the non-production real test
+bed where possible:
+
+- SMTP temporary failure.
+- SMTP permanent failure.
+- Recipient refusal after partial SMTP acceptance.
+- Connection drop or worker interruption during SMTP.
+- IMAP append failure after SMTP acceptance.
+- Worker restart with queued, claimed, and sending jobs.
+
+For the maintained loopback baseline, run
+`dev/mail-testbed/run_campaign_acceptance.py`. It proves the public Campaign
+path for SMTP acceptance, IMAP append, repeat-send blocking, an SMTP connection
+failure before transmission, an explicit SMTP authentication rejection, an
+explicit temporary `451` response after DATA, partial RCPT refusal, a
+connection loss after complete DATA, and an IMAP authentication rejection
+after SMTP acceptance. Its evidence is an allowlisted classification/count
+projection; raw provider diagnostics and transport/account identifiers are
+deliberately excluded.
+
+The runner also terminates a dedicated OS process executing the registered
+Campaign send task after complete DATA, then invokes the task in a fresh
+process. The unfinished durable attempt must become `outcome_unknown` and the
+endpoint must observe no second connection or DATA transaction. This covers
+the worker task/process boundary but not a broker or daemon.
+
+Run `dev/mail-testbed/run_celery_redelivery_acceptance.py` for the maintained
+Redis/Celery delivery and broker redelivery boundary. It starts an isolated
+Redis Compose service and real Celery workers, kills the first solo worker after complete DATA while the
+late-ack task is unacknowledged, and requires the same task identity to reach a
+replacement worker after Redis visibility recovery. Passing evidence also
+requires durable `outcome_unknown`, an empty broker queue/unacked set, and
+exactly one SMTP connection and DATA transaction. Raw worker logs and task,
+database, endpoint, and credential identifiers are never retained.
+
+That second runner proves local runner-supervised process replacement, not the
+production process manager. Repeat the worker-loss drill under the selected
+systemd, container, Kubernetes, or other production supervisor and the target
+Redis/SMTP infrastructure before deployment approval.
+
+## Shared Build Artifacts
+
+Generated EML is stored through Core's configured object-storage backend under
+opaque Campaign-owned keys. The job records expected byte size, SHA-256 digest,
+and Message-ID. A worker on another node must retrieve and verify those values
+before attempting delivery.
+
+- Do not expose object keys to ordinary campaign users or copy them into
+  business fields.
+- A build failure deletes objects written before the database transaction can
+  commit.
+- Retention starts a job-fenced forward-recovery operation before deletion,
+  commits metadata changes in the Campaign-owned boundary, and independently
+  probes the original locator before reporting success. An unavailable backend
+  leaves an outcome-unknown operation; a deletion/metadata mismatch becomes
+  recovery-required in Ops.
+- A hard process loss between object creation and metadata commit can leave an
+  orphan object. Use the operator-only, dry-run-first Campaign artifact
+  reconciler documented in `CAMPAIGN_BUILD_RECOVERY.md`; it scans one bounded
+  tenant-prefix page, enforces a minimum 24-hour grace period, protects active
+  build fences, and rechecks committed EML and print-output references before
+  deletion.
+- Restore Campaign rows, object storage, and the encryption key to one
+  coordinated recovery point before resuming workers.
+
+For a scaled-runtime drill, build on one API replica, consume from another
+worker, compare the stored evidence, and inject storage failures during build
+and retention.
+
+## Reporting Checks
+
+- Partial delivery must show accepted, failed, and unknown counts separately.
+- Excluded messages must show SMTP and IMAP as `skipped`, with skipped counts
+  and filters separate from unattempted or failed delivery.
+- Accepted and unknown jobs must not appear in retry selections.
+- Reconciled accepted jobs must remain protected from resend.
+- Reconciled not-sent jobs must appear only as explicit retry candidates.
+- The final CSV export should include message id, resolved envelope headers,
+  attachment evidence, EML reference/checksum, latest SMTP response/error, and
+  latest IMAP folder/error before the campaign is considered operationally
+  closed.

+
+## What Campaign is for
+
+Campaign turns governed source data into individually built messages or
+printable output and then controls their review, delivery, and evidence. It is
+intentionally a composition module: it demonstrates how one user journey can
+use optional Mail, Files, Addresses, Distribution Lists, Templates, Postbox,
+and Notifications capabilities alongside Core access/audit infrastructure
+without copying ownership from those modules. Policy may consume Campaign
+context through a narrow capability; Campaign does not import Policy.
+
+Campaign owns:
+
+- the communication purpose, content, campaign-local fields, and templates;
+- campaign-local recipient snapshots, exclusions, and personalization;
+- message and attachment rules for a version;
+- validation, review, build, queue, and delivery-control state;
+- the durable jobs and attempts needed to explain delivery outcomes; and
+- campaign-specific reports, shares, and frozen execution evidence.
+
+Campaign does not own:
+
+- SMTP/IMAP profiles, credentials, protocol adapters, or mailbox policy;
+- long-lived address-book master data, consent lifecycle, or deduplication;
+- managed file bytes, connector credentials, or external-file provenance;
+- general-purpose workflow definitions; or
+- global identity, organization, permission, or retention policy.
+
+Those boundaries matter in both persistence and UI. A campaign references an
+authorized Mail profile and managed file versions; it must never become a
+second secret store, file store, or address directory.
+
+## Process view
+
+The supported process is a controlled progression, not a single "send" call:
+
+```text
+create/edit
+    -> validate and resolve policy/integrations
+    -> review warnings and blockers
+    -> build exact recipient messages and/or printable artifacts
+    -> complete review and queue
+    -> selected Mail, Postbox, or print effect per job
+    -> optional IMAP append per accepted job
+    -> report, retry, reconcile, or correct
+    -> archive when no active/uncertain delivery remains
+```
+
+Campaign status summarizes the whole campaign. Version workflow state describes
+the selected immutable/editable version. Each recipient job separately records
+build, validation, queue, SMTP, and IMAP state. Operators must use the job-level
+states when deciding whether another external effect is safe.
+
+Important distinctions:
+
+- **Validation lock** is the reversible lock created by a successful
+  validation/build path. Editing requires unlocking and invalidates derived
+  evidence as appropriate.
+- **User lock** is an explicit audit-safe lock. A permanently locked or
+  delivery-final version is not edited in place; create an editable successor.
+- **SMTP accepted** means the provider accepted the message. It does not prove
+  inbox delivery, reading, or business acknowledgement.
+- **Outcome unknown** means an attempt may have had an external effect. It must
+  be investigated and reconciled before retry.
+- **IMAP append** is a separate effect after SMTP acceptance. An append failure
+  is not evidence that sending failed.
+- **Archive** preserves evidence. Draft-only campaigns without built, locked,
+  or delivery evidence may be deleted where policy allows; evidence-bearing
+  campaigns are archived instead.
+- **Copy campaign** creates a new campaign and one fresh editable version from
+  the selected source version. It copies configuration, but never delivery
+  jobs, outcomes, shares, locks, or audit evidence.
+- **Archive historical version** hides only a non-current version from the
+  default history. It does not change the version's workflow state or remove
+  configuration, reports, delivery results, or audit evidence.
+
+Campaign lifecycle confirmations are bound to the state shown in the UI. If a
+job, version, share, or campaign state changes before confirmation, the server
+rejects the stale action and requires a reload. The lifecycle-policy response
+states the applicable built-in rule and the reason for every unavailable
+action.
+
+## User tasks
+
+### Prepare a campaign
+
+1. Create a campaign and confirm its owner or owning group.
+2. Define global settings, fields, templates, and recipient data.
+3. Import one-off recipient data or select a reusable Addresses source when the
+   optional capability is installed. Review source provenance and stale-source
+   warnings; Campaign freezes the selected rows rather than following later
+   directory changes silently.
+4. Select managed attachments through Files. Server/API campaigns do not accept
+   arbitrary local paths. Preview rules and unmatched files before building.
+5. Open **Mail settings** and select an available Mail profile. The campaign
+   stores only `server.mail_profile_id`; it never accepts SMTP/IMAP settings,
+   usernames, passwords, or credential references.
+   If the selected profile permits a campaign-scoped Mail credential, that
+   credential remains Mail-owned even though it is created from this surface.
+   For that credential and for password-valued campaign fields, the shared
+   password generator keeps its candidate separate from the form until **Use
+   password** is explicitly confirmed. Copying a candidate does not save or
+   submit it.
+6. Save the editable version, validate the relevant sections, and resolve every
+   blocking issue. Warnings remain explicit review decisions.
+7. Build the exact messages and inspect recipient, addressing, template,
+   attachment, and generated-message evidence.
+
+If a selected optional module is absent, Campaign remains loadable and explains
+which function is unavailable. It must not fail startup because Mail, Files, or
+Addresses is not installed.
+
+### Review and complete review
+
+The reviewer should verify the immutable candidate that will be delivered, not
+just the authoring form:
+
+1. Confirm purpose, owner, selected version, and recipient count.
+2. Inspect blocking errors, warnings, exclusions, and recipients requiring
+   review.
+3. Inspect representative and exceptional rendered messages, including From,
+   To/CC/BCC, Reply-To, subject, body, and attachment evidence.
+4. Confirm the selected Mail profile is authorized for the campaign's current
+   tenant and owner context.
+5. Confirm attachment behavior when a rule matches no files, ZIP/password
+   behavior, and any recipient-specific files.
+6. Record review completion and the inspected message keys through the review
+   surface. Validation, build, review, and exception evidence records the actor,
+   timestamp, and immutable build token/message digest where applicable. If
+   content, recipients, attachment inputs, owner context, or non-secret
+   transport identity changes, revalidate and rebuild.
+
+The Review & Send surface separates three kinds of attention. Critical
+blockers must be corrected before delivery, individual review items require a
+recorded message decision, and non-critical group items may be acknowledged
+together after individual review is complete. Each warning or blocker names
+the required action, the responsible role, and the workspace to open. The
+review summary keeps reviewed and remaining counts visible; a completed review
+acknowledges the group items and remains bound to the current build token.
+
+This evidence is the Campaign input to separation-of-duties policy. Generic
+approve/reject chains, delegation, substitutions, escalation, and signatures
+belong to the optional Approvals capability. Campaign must not claim an
+approval merely because validation, building, or message review completed.
+
+When a campaign has an Approval request reference, mock and real delivery
+resolve `approvals.requests` and require an approved request for the exact
+`campaign_version` subject and current version id. A missing Approvals module,
+unknown request, pending/rejected chain, or approval for an older version blocks
+delivery with an explicit requirement. Campaign stores the approval reference,
+not Approval tables; changing the campaign version requires a new exact-subject
+approval.
+
+Normal readers and reviewers see business state and safe evidence. Process-local
+paths, storage keys, worker claim tokens, and raw provider diagnostics require
+the dedicated diagnostic permission and must not leak through ordinary campaign,
+version, job, or report responses.
+
+Campaign now provides a separate aggregate **Reports** surface for readers with
+`campaigns:report:read` and access to the campaign. It loads only the safe
+aggregate projections, applies small-cell suppression, and offers no recipient
+rows, drill-down, filtering, export, or delivery actions. The recipient-aware
+**Campaign Report** still requires recipient-read access and does not yet hide
+every action control that the actor lacks. The server authorizes each action,
+but permission-aware action visibility on that detailed surface remains open
+work; do not confuse it with the aggregate reader experience.
+
+The module-local aggregate surface remains at `/campaigns/reports`. When the
+optional Reporting module is enabled, Campaign also contributes the same
+recipient-free projection as the `campaigns/delivery-outcomes` report provider.
+Reporting owns `/reports`, records the run purpose, effective audience, source
+campaign/version revision, privacy transformations, retention, actor/time,
+output hash, and export history, and applies Policy before returning the
+result. Campaign does not register a fallback `/reports` route when Reporting
+is absent.
+
+The detailed Campaign Report includes the selected campaign's effective
+retention policy, its system/tenant/owner/campaign provenance, and the current
+evidence state. It distinguishes retained, redacted, expired, partially
+minimized, unavailable, and not-applicable source JSON, stored report detail,
+generated EML, and Postbox-copy evidence. When Policy is absent, the report
+shows the platform defaults and explicitly warns that automated retention
+enforcement is unavailable. Retention removes or minimizes detail; aggregate
+counters and audit references may remain so outcomes can still be explained.
+
+### Deliver and resolve outcomes
+
+Use the [delivery runbook](CAMPAIGN_DELIVERY_RUNBOOK.md) for the detailed
+operator sequence.
+
+At a minimum:
+
+1. Queue only a validated, locked, built version. Use **Queue for workers** for
+   ordinary batches; the durable progress remains visible after leaving and
+   returning to Review and send.
+2. Use **Send now** only when the exact persisted eligible build is within the
+   effective synchronous limit shown by the UI. The default deployment limit
+   is 25 recipient jobs. The backend repeats the count and preflights every
+   message and the Mail profile revision before contacting SMTP.
+3. Treat `smtp_accepted` as protected from ordinary retry.
+4. Retry `failed_temporary` explicitly after inspecting the cause.
+5. Include `failed_permanent` only after correcting the cause and making a
+   conscious override.
+6. Never retry `outcome_unknown` blindly. Inspect SMTP/provider evidence and
+   reconcile it as **accepted** or **not sent**, with a note identifying the
+   evidence.
+7. Process append-to-Sent only for SMTP-accepted jobs and investigate append
+   failure independently. Never retry an `outcome_unknown` IMAP append blindly:
+   reconcile mailbox evidence as **appended** or **not appended** with a note.
+   Only the latter becomes explicitly retryable, and neither decision resends
+   the already SMTP-accepted message.
+8. Archive only after active and uncertain effects are resolved.
+9. Use **Delete draft** only for an untouched draft. If retained evidence or an
+   active share exists, revoke the share where appropriate or archive instead.
+
+Pause stops new eligible work but cannot undo a provider effect already in
+progress. Cancel marks work that has not yet produced a protected SMTP outcome;
+it cannot recall accepted mail.
+
+The deployment ceiling is configured with
+`GOVOPLAN_CAMPAIGN_SYNCHRONOUS_SEND_MAX_RECIPIENTS` (0 disables Send now; the
+accepted range is 0–500). A tenant may only narrow that ceiling with
+`tenant.settings.campaign_delivery_policy.synchronous_send_max_recipients`.
+The effective value and source are returned by the protected delivery-options
+API, recorded for successful/rejected synchronous commands, and stated in the
+configured handbook topic.
+
+### Test and one-message actions
+
+The current baseline includes mock send, queue dry-run, synchronous immediate
+delivery, sending one selected job, retry selection, and unattempted-job
+selection. Their audit and state behavior is not yet the final vocabulary
+accepted for issue `govoplan-campaign#69`.
+
+The intended distinction is:
+
+- **Test:** deliver once to the configured test path, audit it, and leave the
+  production job unsent.
+- **Single send:** send one unsent job, audit it, and mark its production effect
+  complete.
+- **Single resend:** intentionally send one job again regardless of an earlier
+  failure or acceptance, with distinct authority, warning, reason, and audit.
+
+Until that slice is implemented and target-tested, do not present the existing
+buttons as a complete resend policy. Ordinary retry protection remains the safe
+default.
+
+## Data and evidence model
+
+### Versions and snapshots
+
+Editable campaign JSON is versioned. Build creates recipient jobs and an
+execution snapshot. A new profile-only snapshot contains the stable Mail
+profile id, delivery policy/evidence, and opaque Mail-issued transport
+revisions. It contains no resolved SMTP/IMAP configuration or credentials.
+
+At delivery time Mail re-authorizes the profile, compares the expected opaque
+revisions, resolves credentials inside the same Mail-owned operation, and
+performs the transport effect. Campaign receives only the sanitized result it
+needs for job state and evidence. This same-call check prevents a
+validate-then-use race across the module boundary.
+
+Credential rotation that does not change the non-secret transport identity may
+continue to satisfy the snapshot. A host, account identity, protocol, sender,
+or other revisioned transport change stops delivery until the campaign is
+revalidated and rebuilt.
+
+### Existing legacy database records
+
+The current Campaign database may contain versions with inline SMTP/IMAP
+material. No separate historical Campaign JSON corpus exists. Inline transport
+material in those rows is treated as inert legacy data and is never interpreted
+as an executable Mail configuration:
+
+- public responses remove legacy transport fields and secrets;
+- validation, build, queue, retry, and delivery fail closed;
+- computed previews that require a current Campaign configuration return an
+  actionable validation problem instead of a server error;
+- an editable version changes to profile-only form only through an explicit
+  Mail-settings save; and
+- a locked version is preserved and must be forked to an editable successor.
+
+Normal database backup/restore and access controls cover those rows together
+with the rest of the current database. There is no separate historical-JSON,
+backup-scanning, or inline-secret migration program. Restoring an existing
+legacy row preserves it as inert evidence and does not make it deliverable.
+
+### Recipient and attachment evidence
+
+The delivery record should be able to identify:
+
+- source/import context and the frozen recipient row;
+- effective addressing and message id;
+- template inputs and unresolved-placeholder decisions;
+- managed file/version ids, source provenance, checksums, and ZIP evidence;
+- generated EML checksum and size;
+- Mail profile reference and opaque transport revisions;
+- each SMTP and IMAP attempt, its classification, safe provider response, and
+  reconciliation note; and
+- actor/system trigger, timestamps, policy context, and corrections.
+
+An excluded recipient/message is a completed validation decision, not a
+pending delivery. Its SMTP and IMAP states are both `skipped`; it is counted and
+filterable separately from unattempted, failed, accepted, and append outcomes.
+No SMTP or IMAP attempt exists for such a row. If historical data contains
+actual transport evidence despite an exclusion marker, that evidence is
+preserved for audit and reconciliation rather than relabelled.
+
+## Administration and policy
+
+### Roles and permissions
+
+The supplied role templates deliberately separate preparation, review, and
+delivery:
+
+- **Campaign manager** prepares, validates, and builds campaigns and recipients.
+- **Campaign reviewer** inspects prepared material and records review
+  completion for the exact messages checked.
+- **Campaign sender** queues, sends, pauses/resumes/cancels, retries, reconciles,
+  reads reports, and has diagnostic access.
+
+Administrators may compose narrower roles from the declared permissions. Keep
+these separations where institutional policy requires four-eyes approval. Mail
+profile use additionally requires `mail:profile:use`; profile and credential
+administration remains a Mail permission.
+
+Campaign access is also constrained by tenant, owner/group context, and explicit
+shares. A share grants only its declared campaign permission; it does not grant
+Mail credentials, Files administration, or tenant-wide recipient access.
+
+### Configuration checklist
+
+- Install compatible Core and Campaign versions. Access and base audit are Core
+  infrastructure; install optional Mail, Files, Addresses, Notifications, and
+  Policy modules only where the configured journey requires them.
+- Configure Mail profiles and policy in Mail, not in campaign fixtures or JSON.
+- Configure Files storage/connectors and attachment permissions in Files.
+- Define role assignments and separation-of-duty policy.
+- Configure Redis/Celery for durable batch workers where production volume
+  requires it. Local execution is a development/small-run mode, not horizontal
+  worker coordination.
+- Set rate limits for the target provider. Mail may use Redis for shared
+  throttling when present and a process-local fallback in development.
+- Establish retention, deletion, archive, report-export, and diagnostic-access
+  policy before production recipient data is loaded.
+- Use non-production SMTP/IMAP identities and the maintained examples before
+  allowing a production profile.
+
+### Owner transfer
+
+Mail profile visibility can depend on campaign owner or group. Transferring an
+editable campaign with a selected profile clears/requires reselection and
+revalidation. A locked or delivery-final version is never silently rewritten;
+create an editable successor.
+
+## Operations and recovery
+
+### Health to observe
+
+- database and migration health;
+- compatible module interface versions;
+- queue publication, worker heartbeat, claim age, and backlog;
+- SMTP/IMAP profile test result and deployment egress policy;
+- Mail profile authorization/transport-revision mismatch;
+- Files resolution and frozen attachment availability;
+- counts by queue, SMTP, IMAP, and reconciliation state; and
+- audit and report generation failures.
+
+### Worker interruption
+
+A crashed worker can leave a job claimed or sending. Do not infer non-delivery
+from worker loss. If the SMTP boundary may have been crossed, classify the
+outcome as unknown and reconcile from external evidence. Only work that is
+provably unattempted may be returned to an ordinary queue.
+
+### Retry and reconciliation
+
+Retries create new attempt evidence; they do not overwrite the previous
+attempt. Reconciliation is a privileged factual correction supported by an
+operator note. Repeated automated requests should be idempotent for the same
+eligible job state; a deliberate resend is a different, not-yet-finalized
+business action and must never be disguised as a retry.
+
+### Backups and restoration
+
+Back up Campaign, Mail, Files, Core/Audit, and shared storage consistently for
+the composition. A database restore without generated EML/file storage, or file
+storage without matching metadata, does not reconstruct the evidence chain.
+After restore, keep outbound delivery paused until queue/attempt state and
+provider evidence have been reconciled; never let restored accepted jobs send
+again merely because a queue message was lost.
+
+For unreferenced generated objects after process loss, platform operators first
+run the bounded Campaign artifact inventory in dry-run mode. Apply only an
+inspected page with a unique incident idempotency key. The cleanup keeps exact
+keys out of ordinary Campaign responses, does not clear database references,
+and leaves storage failures in the Core recovery ledger for explicit retry.
+
+### Incident handling
+
+1. Pause new delivery when duplicate or unknown effects are possible.
+2. Preserve database, queue, provider, worker, and audit evidence.
+3. Scope affected campaigns/jobs without exposing recipient content broadly.
+4. Reconcile uncertain jobs individually or through an approved bounded tool.
+5. Correct configuration in its owning module, then revalidate/rebuild where
+   revisioned transport inputs changed.
+6. Record the incident reference and recovery rationale in audit evidence.
+
+## Composition and integration contracts
+
+Campaign has one required platform dependency: Core. Optional module behavior
+is discovered through versioned, Core-mediated capabilities; Campaign must not
+import optional sibling ORM, services, or WebUI implementation.
+
+Current principal contracts include:
+
+| Contract | Direction | Purpose |
+| --- | --- | --- |
+| `mail.campaign_delivery` 0.2.x | Mail -> Campaign | Summarize a known reference; authorize and revision-gate it; send/append using Mail-owned configuration and credentials; return sanitized results |
+| `files.campaign_attachments` 0.1.x | Files -> Campaign | Select/materialize governed file versions and preserve campaign usage/evidence |
+| `addresses.lookup` 0.1.x | Addresses -> Campaign | Optional address suggestions |
+| `addresses.recipient_source` 0.1.x | Addresses -> Campaign | Optional versioned recipient-source snapshots |
+| `dist_lists.source` / `dist_lists.expand` 0.1.x | Distribution Lists -> Campaign | Discover, preview, and freeze reusable audiences without importing module internals |
+| `templates.catalog` / `templates.renderer` 0.1.x | Templates -> Campaign | Select compatible published printable templates and produce deterministic, evidence-bearing artifacts |
+| `campaigns.access` 0.1.x | Campaign -> platform | Explain campaign access/existence without exporting ORM objects |
+| `campaigns.mail_policy_context` 0.1.x | Campaign -> Mail | Resolve campaign tenant/owner context for Mail policy |
+| `campaigns.delivery_tasks` 0.1.x | Campaign -> workers | Execute narrow queued send/append tasks |
+| `campaigns.retention` 0.1.x | Campaign -> retention | Apply Campaign-owned retention behavior |
+
+Breaking payload or ownership changes require an interface-version bump and a
+release-composition alignment gate. Optional absence must be tested physically,
+not only hidden in navigation.
+
+### Bulk recipient activation
+
+Recipient data can activate all currently inactive rows or deactivate all
+currently active rows. The action displays the exact affected count and
+requires confirmation. It changes only the local Campaign draft until the
+operator saves. Saving follows the ordinary versioned Campaign update path, so
+the resulting recipient state is retained in version and protocol evidence and
+any stale validation, build, or review evidence is invalidated.
+
+### Reusable Distribution Lists
+
+When Distribution Lists is available, Recipient data offers a separate import
+dialog. The author selects a visible list revision, supplies declared
+parameters, requests candidate channels, and previews included, excluded,
+stale, ambiguous, suppressed, policy-blocked, and provider-unavailable results.
+The final action freezes an idempotent Distribution Lists snapshot and copies
+the resulting rows into the editable Campaign version.
+
+Each copied row retains the list and revision IDs, definition and expansion
+hashes, snapshot ID, source entry IDs, provider references, channel candidates,
+the explicitly selected primary route, optional fallback, and the decision
+explanation. Campaign-only fields, attachment rules, review state, and outcomes
+remain local to Campaign and never mutate the reusable list.
+
+A later list revision only raises a drift warning. Refresh is deliberate and
+uses append or replace; saving that changed Campaign version clears prior
+validation, build, review, and execution state through the normal content
+invalidation path. Preferred or single usable candidates are preselected
+visibly; ambiguous rows must be decided before freezing. Postal and
+internal-mail routes remain active when a compatible published Templates output
+is selected.
+
+### Governed hybrid and printable delivery
+
+Campaign supports Mail, Postbox, printable output, and bounded ordered
+fallbacks without making any of those provider modules mandatory. Opt-in and
+channel-preference data are inputs to the visible routing decision; they never
+silently cause duplicate delivery.
+
+For a printable route, select a published label, envelope, serial-letter,
+form-letter, list-layout, or generic template on the Template page. Validation
+checks the selected revision, output format, and required fields. Build sends
+one deterministic item collection to `templates.renderer`, records template,
+input, output, actor, route, and artifact hashes, and stores the resulting
+artifact through Files when configured. The review stage exposes that exact
+artifact and its hashes before execution.
+
+Each recipient job records an idempotent print acceptance attempt for its item
+in the frozen artifact. `mail_then_print` and `postbox_then_print` invoke print
+only after a confirmed rejection before acceptance. An accepted or
+outcome-unknown digital effect never falls through to print because that could
+produce duplicate delivery. Reports and CSV exports include route provenance,
+print state, attempts, artifact reference, and hashes.
+
+Without Templates, Campaign still loads and Mail/Postbox authoring remains
+available; validation explains why a configured print route cannot proceed.
+Without Files, Templates may return a bounded artifact instead of a managed
+file. Campaign copies that payload into shared object storage and exposes it
+through the Campaign ACL plus `campaigns:recipient:read`; it never redistributes
+the broader Templates URL. A print-only Campaign does not require Mail or Postbox.
+
+### External API expectations
+
+- Tenant and campaign access are evaluated for every operation.
+- Writes require CSRF/auth behavior supplied by Core and the specific declared
+  scope.
+- Queue/retry/reconcile endpoints operate on persisted state and return safe
+  summaries; initiating HTTP success is not proof of external delivery.
+- Delta endpoints are optimization surfaces, not a separate source of truth.
+- Report exports contain permitted business/evidence fields but no credentials,
+  local paths, storage keys, or worker claims.
+
+## Assurance model
+
+### Security invariants
+
+- No new campaign payload, fixture, response, or execution snapshot contains
+  SMTP/IMAP settings or credentials.
+- Mail resolves credentials and performs transports inside Mail-owned calls.
+- Every real connector peer is validated and pinned at connection time under
+  deployment-wide private-network policy.
+- API/server attachment paths use managed Files references; arbitrary and
+  traversal-capable local paths are rejected.
+- Public responses recursively remove infrastructure locators and secret-like
+  legacy fields.
+- Accepted and outcome-unknown jobs are protected from ordinary retry.
+- Diagnostic permission is separate from campaign read/report access.
+
+### Privacy
+
+Recipient fields and rendered messages may contain personal or sensitive data.
+Grant recipient read/export, report export, and diagnostic access separately.
+Prefer aggregate status for readers who do not need recipient detail. Define
+purpose, lawful basis, minimization, export control, and retention before the
+campaign starts; do not use Campaign as a substitute consent or address-master
+system.
+
+The Core data-subject-request workflow discovers Campaign through the optional
+`privacy.dsar.campaigns` capability. After the request's email, membership, and
+namespaced Campaign references have been independently authorized and
+corroborated, the provider searches only the effective tenant and isolates the
+matching recipient entries and jobs. Its JSON result includes safe Campaign,
+version, delivery-attempt, schedule, report-projection, share, import-mapping,
+attachment, and generated-artifact metadata. Generated EML bytes and paths,
+storage locators, delivery target snapshots, worker claims, idempotency
+material, credentials, secret-like values, and unrelated recipients are never
+embedded in that result. Authorized Campaign and Files review surfaces remain
+the source for content that cannot safely be copied into the DSAR case.
+
+Built, locked, published, terminal, delivered, or corrected records are
+retained with an explicit reason and continue through Campaign's configured
+retention and redaction process. Draft recipient content and user-owned
+attachment content require coordinated manual review because copies may span
+version JSON, jobs, generated messages, and managed files. The provider can
+idempotently revoke an active share aimed at the subject and delete the
+subject's personal recipient-import mapping profile. It does not rewrite
+delivery evidence, delete generated artifacts, or report derived Campaign
+counts as a separate store. Re-running an approved action is safe: already
+revoked or absent data is reported as unchanged, and tenant, subject, and row
+ownership are revalidated immediately before mutation.
+
+### Audit and destructive actions
+
+Material authoring, validation, locking, review, queueing, send, retry,
+reconciliation, sharing, owner transfer, archive, and permitted deletion actions
+emit attributable evidence. Audit details must be non-secret and should refer to
+stable ids rather than repeat message bodies or credentials.
+
+Draft deletion is allowed only while no audit-relevant build, delivery job, or
+lock exists. Evidence-bearing campaigns are archived. Destructive module
+retirement remains a separately confirmed installer operation with backup and
+retirement evidence.
+
+The Campaign **Audit** page is currently an explained handoff, not a second
+audit store: Campaign emits bounded platform audit records and authorized
+readers inspect them in Administration > Tenant audit. A future object-scoped
+projection may improve that navigation without duplicating Audit ownership.
+Evidence-bundle export and offline verification remain owned by Audit #3.
+
+The advanced **JSON** page displays and downloads the complete campaign
+configuration available to the current campaign reader. It contains no inline
+transport secrets, but recipient, message, and attachment fields may contain
+personal data. The UI therefore identifies it as sensitive expert output;
+campaign access and export purpose remain the governing controls.
+
+## Reference-composition acceptance
+
+Campaign is ready to serve as the demonstration module only when all of the
+following are repeatable in a pinned clean installation:
+
+1. The maintained examples validate and build with Mail/Files present, and
+   Campaign still starts with each optional module absent.
+2. A user can import recipients, select managed files, choose an authorized Mail
+   profile, validate, review, build, and queue without entering transport ids or
+   secrets manually.
+3. Campaign JSON and all ordinary APIs reject/omit inline transport material;
+   legacy records are visible as migration-required and cannot execute.
+4. SMTP success, temporary/permanent failure, connection loss, worker loss,
+   outcome unknown, retry, reconciliation, IMAP success, and IMAP failure have
+   tested, non-duplicating outcomes against the target environment.
+5. Author, reviewer, sender/operator, reader, and administrator views use the
+   central component system and expose only task-relevant actions.
+6. Reports and audit can reconstruct recipient/message/file/profile/attempt
+   evidence without exposing secrets or ordinary-reader infrastructure details.
+7. Clean install, upgrade, backup/restore, module permutations, version
+   alignment, security audit, and target SMTP/IMAP tests pass.
+8. This handbook and its adaptive Docs topics match the shipped UI wording and
+   distinguish implemented behavior from planned work.
+
+## Explicitly planned, not yet claimed
+
+The following are part of the selected reference journey but are not implied by
+the current baseline:
+
+- the final audited **test / single send / single resend** semantics;
+- durable, idempotent Campaign report delivery through a Mail-owned outbox
+  ([`govoplan-mail#17`](https://git.add-ideas.de/GovOPlaN/govoplan-mail/issues/17));
+- a fully packaged one-command Campaign reference composition with production
+  policy presets and target-provider certification;
+- function-bound Postbox delivery (stage 2 of the reference program);
+- generic workflow-driven campaign transitions.
+
+Each item needs an owning issue, implementation, failure tests, documentation,
+and release evidence before the wording above can move from planned to current.

+# Example Campaigns And Release Checklist
+
+This document defines the campaign examples and release gates that should be
+kept working before a GovOPlaN Campaign release is tagged.
+
+## Example Campaign Set
+
+Maintain fixtures or guided examples for these scenarios. The canonical
+scenario catalogue lives in `examples/README.md`; committed fixture files should
+be added under `examples/` only when they validate against the current campaign
+schema and are safe to run in non-production environments.
+
+- [`simple-announcement`](../examples/simple-announcement/campaign.json), a
+  credential-free campaign with one active recipient and no attachments; its
+  automated acceptance check physically blocks Mail and Files imports, denies
+  network connections, and validates/builds from an unrelated temporary
+  workspace
+- multi-recipient message with To, CC, BCC, Reply-To, bounce, and disposition
+  notification fields
+- campaign with global attachments and recipient-specific attachment rules
+- campaign with password-protected ZIP attachments
+- campaign using a reusable mail profile from the mail module
+- legacy inline SMTP/IMAP campaign rejected with an actionable profile-migration
+  error and no returned transport data
+- campaign with validation warnings that may be sent only after explicit review
+- campaign with blocked recipients or attachment errors that must not be sent
+- mock delivery campaign that captures SMTP and IMAP append messages in the mail
+  development mailbox
+- [`greenmail-delivery`](../examples/greenmail-delivery/campaign.json), a
+  credential-free real-delivery Campaign materialized with a temporary
+  Mail-owned profile by the loopback acceptance runner
+
+## Fixture Rules
+
+- Examples must not contain production recipient data or production credentials.
+- Attachment examples should use deterministic small files and checksums.
+- Mail secrets belong only to encrypted Mail profiles and must never appear in
+  a campaign fixture, placeholder, or campaign-local secret reference.
+- Examples that require optional modules must declare the required modules and
+  capabilities in their README or fixture metadata.
+- Examples must stay valid when files or mail modules are physically absent,
+  with optional behavior disabled instead of import failures.
+
+## Release Gates
+
+Before tagging a campaign release:
+
+- Review `examples/README.md` and update the scenario catalogue when a release
+  adds or removes delivery behavior.
+- Run `python -m unittest discover -s tests -p 'test_example_campaigns.py'` and
+  retain its isolated validate/build result as release evidence.
+- Run core module permutation tests with campaign installed both with and
+  without files/mail.
+- Validate and build each maintained example campaign.
+- Run the mock delivery example when the mail development mailbox capability is
+  enabled.
+- Run the GreenMail SMTP/IMAP smoke for a non-production real delivery path.
+- Run `dev/mail-testbed/run_campaign_acceptance.py` and retain its bounded JSON
+  projection. It must show one SMTP acceptance, one IMAP append, no duplicate
+  effect from a repeated ordinary send, matching Campaign report/audit state,
+  and no resolved transport material in Campaign JSON or its execution
+  snapshot. Its controlled endpoint evidence must also show explicit SMTP 451,
+  partial RCPT refusal, post-DATA ambiguity, and task-process interruption
+  classifications without retaining addresses or provider diagnostics.
+- Treat the task-process restart proof separately from the still-open
+  Redis/Celery broker redelivery and daemon-supervision check; the coverage
+  projection must keep `celery_broker_redelivery` false.
+- Run `dev/mail-testbed/run_celery_redelivery_acceptance.py` as a separate
+  destructive worker-loss check. Retain its bounded evidence only when the same
+  broker task is observed at both workers, the durable state is
+  `outcome_unknown`, broker queue/unacked counts are zero, and the controlled
+  SMTP endpoint observed one connection and one DATA transaction. This closes
+  local Redis/Celery redelivery coverage, while production supervisor and
+  target-provider coverage remain false until separately tested.
+- Confirm reusable mail profile selection is revalidated after campaign owner
+  transfer.
+- Confirm every inline SMTP/IMAP field is rejected on import/write, omitted
+  from responses, and blocked from legacy execution until explicitly migrated.
+- Confirm execution snapshots store only the Mail profile reference and
+  opaque Mail-owned transport revisions, not resolved transport material.
+- Confirm delivery reports include SMTP outcome, IMAP append outcome, latest
+  error, generated EML reference, and attachment evidence.
+- Confirm retries cannot resend messages already accepted by SMTP unless an
+  explicit reconciliation path allows it.
+
+## Ownership Transfer Check
+
+Reusable user/group mail profiles are owner-context-sensitive. When campaign
+ownership changes, the editable current version must require profile reselection
+and validation before live delivery. A locked delivery-final version should not
+be silently rewritten.
+
+## Delivery Checklist
+
+Use the Review & Send preflight panel and the delivery runbook together:
+
+1. Validate and resolve all blocking policy/data issues.
+2. Build exact messages.
+3. Review warnings, generated recipients, body content, and attachment evidence.
+4. Run mock delivery if available for the release channel.
+5. Test the selected Mail profile against non-production infrastructure.
+6. Send only after queue, rate limit, and append-to-Sent behavior are understood.
+7. Reconcile failed, unknown, or pending jobs from the report/audit surfaces.

+# Campaign and Mail Profile Boundary
+
+## Product view
+
+A campaign chooses an authorized Mail profile. It does not define a mail
+server. The Campaign module owns recipients, content, attachment rules,
+delivery intent, review state, and delivery evidence. The Mail module owns the
+SMTP/IMAP endpoints, encrypted credentials, connection tests, profile policy,
+and runtime transport adapters.
+
+The persisted campaign contract is therefore deliberately narrow:
+
+```json
+{
+  "server": {
+    "mail_profile_id": "stable-mail-profile-id"
+  }
+}
+```
+
+No `server.smtp`, `server.imap`, `server.credentials`, credential-inheritance
+override, or password is valid campaign JSON.
+
+## User journey
+
+1. A Mail administrator creates and tests a reusable profile in Mail.
+2. A campaign author opens **Mail settings** and selects one profile available
+   for the campaign's tenant, owner, and policy context.
+3. Campaign stores only the stable profile identifier.
+4. Validation asks Mail to authorize the active profile and returns only
+   availability flags plus opaque Mail-owned transport revisions. Reading that
+   summary does not decrypt credentials.
+5. Build stores the profile identifier, delivery policy, job manifest, and
+   non-secret transport revisions as execution evidence. It stores no
+   resolved host, username, password, or other transport material.
+6. A delivery worker invokes one Mail-owned effect operation. Mail re-authorizes
+   the profile, resolves credentials, compares the expected transport
+   revision, checks policy, and sends or appends without returning transport
+   material to Campaign. If the selected profile or its non-secret transport settings
+   changed after build, delivery stops until the campaign is revalidated and
+   rebuilt. A password rotation that leaves the transport identity unchanged
+   does not invalidate the build.
+7. Mail returns only Campaign-owned envelope addresses, counts, sanitized
+   refusal classifications/status codes, or the selected Sent folder. Raw
+   server banners, provider bytes, host details, and credentials never enter
+   Campaign attempts or public evidence.
+
+Non-dry Campaign report email currently fails closed. It must not bypass the
+durable job/effect model through a direct SMTP call. Re-enabling it requires the
+Mail-owned idempotent outbox, attempt, unknown-outcome, and reconciliation path
+tracked in
+[`govoplan-mail#17`](https://git.add-ideas.de/GovOPlaN/govoplan-mail/issues/17).
+Report generation and dry-run validation remain separate from an external
+effect; recipient-level exports require recipient-export authorization.
+
+Campaign authors need `mail:profile:use` in addition to the relevant Campaign
+permission. Profile visibility remains governed by Mail policy and campaign
+owner context.
+
+## Existing database rows and migration
+
+The current database can contain campaign versions with inline SMTP/IMAP
+settings or credentials. There is no separate historical Campaign JSON corpus
+to import or remediate. GovOPlaN treats those inline fields as inert legacy
+material and does not delete or rewrite the stored audit rows automatically:
+
+- API responses omit all legacy transport fields and secrets and expose a
+  `mail_profile_migration_required` marker.
+- validation, build, queue, retry, and delivery fail closed with an actionable
+  profile-migration error;
+- unrelated edits cannot silently scrub the legacy fields;
+- an editable version is migrated only through an explicit Mail-settings save
+  with an authorized profile; and
+- a locked version remains unchanged. Creating its editable successor records
+  the migration while retaining the locked source as audit evidence.
+
+Legacy execution snapshots are likewise retained but cannot be used for
+delivery. Revalidate and rebuild an editable profile-only version. Normal
+database backup, restore, encryption, and access controls apply to the current
+database as a whole; the product does not define a separate historical-JSON or
+inline-secret recovery workflow. A restored legacy row remains inert and
+fail-closed under the same rules.
+
+## Operator checks
+
+Before live delivery, confirm that:
+
+- the profile is active and still authorized for the campaign owner;
+- SMTP and optional IMAP profile tests pass;
+- validation and build occurred after the latest transport-identity change;
+- append-to-Sent is enabled only when the selected profile has IMAP; and
+- reports show the profile-bound snapshot revisions and delivery outcomes,
+  never credentials or resolved transport configuration.

+Campaigns own campaign-local recipient entries because sending and reporting
+need a frozen recipient snapshot. Long-lived address management is a separate
+domain owned by `govoplan-addresses`.
+
+## `govoplan-campaign` Owns
+
+- campaign-local recipient entries
+- campaign-local recipient import mapping and validation
+- message addressing for a concrete campaign version
+- send/build/report evidence for the exact recipients used
+- campaign-local exclusions, warnings, and review status
+- recipient-specific attachment and template evidence
+
+Campaign data is immutable once a version is built for sending. Later address
+book changes must not rewrite historical campaign evidence.
+
+## `govoplan-addresses` Owns
+
+- Adrema-style address management
+- reusable person, organization, household, and postal-address records
+- reusable email address lists and segments
+- postal-letter recipient views
+- consent, legal-basis, and communication-preference metadata
+- deduplication and merge workflows
+- import/export of reusable address directories
+- address quality checks and change history
+
+The addresses module provides the UI/module boundary for this domain and should
+grow stable DTOs and capabilities that campaigns, mail, forms, reporting,
+portal, and postbox modules can consume without direct imports.
+
+## Current Integration Contract
+
+The campaign module asks the platform registry for address capabilities and
+keeps working when they are absent. It must not import `govoplan-addresses`
+ORM models, services, or WebUI components.
+
+When `addresses.lookup` is available, campaign recipient address fields use it
+for autocomplete. The campaign page may warm a small suggestion cache with an
+empty query and then query by typed text as the user edits sender, reply-to,
+global recipient, or per-recipient address fields.
+
+When `addresses.recipient_source` is available, campaign offers a separate
+address-book/list import flow. This is for importing reusable recipient sources
+into the campaign recipient table; normal one-off address entry still happens
+inside the address fields while typing.
+
+The capability should return snapshots, not live ORM objects:
+
+- selected source id and display label
+- normalized recipient rows
+- provenance fields for source, segment, legal basis, and import time
+- update markers so campaigns can show whether a draft is based on stale source
+  data
+
+Campaign stores the resolved snapshot in the campaign version. It may keep a
+reference to the address source for traceability, but the built campaign remains
+auditable even if the address source changes later.
+
+If the source revision changes after import, campaign shows a stale-source
+warning and lets the user reopen the import dialog with that source preselected.
+The user still chooses append or replace; campaign should not silently rewrite
+recipient rows.
+
+Distribution Lists is a separate, provider-neutral audience boundary. Campaign
+uses `dist_lists.source` and `dist_lists.expand` to preview and freeze mixed
+email, postal, internal-mail, and portal candidates. It stores exact list,
+revision, source-entry, provider, policy, route, exclusion, and expansion-hash
+evidence with the Campaign version. Addresses remains the contact/contact-point
+owner; Distribution Lists remains the reusable audience owner; Campaign owns
+only its copied recipients, enrichment, route choices, review, and outcomes.
+
+## Non-Goals For Campaign
+
+Campaign should not become the global address book. It should not own:
+
+- deduplication across campaigns
+- consent lifecycle
+- master-data merge policy
+- address-directory permissions beyond campaign use
+- postal address normalization
+- reusable segmentation rules
+
+Those belong in `govoplan-addresses` or a dedicated records/identity module when
+the domain needs stronger governance.

+# Recipient Import Guide
+
+Recipient import lets campaign authors turn spreadsheet-like source data into
+campaign-local recipient entries. It is intentionally campaign-local:
+reusable address books and Adrema-style address management belong in the
+`govoplan-addresses` module.
+
+## Supported Inputs
+
+The current importer is designed for tabular data with a header row. CSV and
+spreadsheet-derived tables should be normalized before import so the campaign UI
+sees:
+
+- column headers
+- row values
+- source filename and sheet name when available
+- a stable ordered and unordered header fingerprint
+
+Avoid importing production secrets or credentials as recipient fields. Recipient
+custom fields may be used in templates and reports, so they should be treated as
+campaign data.
+
+## Mapping Fields
+
+Common headers are detected automatically:
+
+- `email`, `e_mail`, `mail`, `to`, `to_email`, `recipient`,
+  `recipient_email`
+- `name`, `full_name`, `recipient_name`, `to_name`
+- `id`, `entry_id`, `recipient_id`
+
+Authors can map columns to address fields:
+
+- `from`
+- `to`
+- `cc`
+- `bcc`
+- `reply_to`
+
+Rows without a valid `to` address should remain visible with validation issues
+instead of disappearing silently. Authors should be able to fix the source file,
+adjust the mapping, or exclude the row before building the campaign.
+
+## Mapping Profiles
+
+Mapping profiles save a known column layout so repeated imports can reuse the
+same mapping. The importer stores ordered and unordered header fingerprints so a
+profile can distinguish exact column order from equivalent column sets.
+
+Administrators should curate shared profiles only for stable recurring sources.
+Campaign-local profiles are acceptable for one-off work and experiments.
+
+## User Workflow
+
+1. Open the campaign recipient/data import screen.
+2. Upload or paste a tabular source.
+3. Review detected headers and preview rows.
+4. Pick or adjust a mapping profile.
+5. Confirm validation issues, exclusions, and generated recipient ids.
+6. Import into the campaign draft.
+7. Build messages and review recipient-specific evidence before sending.
+
+## Admin Workflow
+
+Administrators should:
+
+- define naming conventions for recurring mapping profiles
+- verify that imported fields have a lawful processing basis for the campaign
+- keep reusable address-directory ownership out of campaigns because
+  `govoplan-addresses` owns that domain
+- use campaign reports and audit evidence to trace which source produced which
+  recipient entries
+- remove obsolete shared profiles when an upstream source layout changes
+
+## Evidence Expectations
+
+The campaign should preserve enough evidence to explain a send:
+
+- source filename and sheet name where available
+- header fingerprints
+- mapping profile id/name when used
+- row number or source id
+- validation status and exclusion reason
+- final recipient addresses used for the built message
+
+The evidence should be available in reports without requiring the original
+source file to be reprocessed.

+# GovOPlaN Campaign Examples
+
+These examples are the maintained scenario catalogue for campaign release
+checks. They are intentionally small and credential-free. Add concrete fixture
+files next to this README only when they can be validated by the current
+campaign schema and do not require production data.
+
+## Scenarios
+
+| Scenario | Required Modules | Release Check |
+| --- | --- | --- |
+| [`simple-announcement`](simple-announcement/campaign.json) | core, access, campaigns | Validate and build one active recipient without attachments while Mail and Files are absent. |
+| `addressing-matrix` | core, access, campaigns | Exercise To, CC, BCC, Reply-To, bounce, and disposition-notification fields. |
+| `global-attachment` | core, access, campaigns; optional files | Build one deterministic attachment and verify evidence. |
+| `recipient-attachment-rules` | core, access, campaigns; optional files | Match recipient-specific attachment rules and verify per-recipient evidence. |
+| `zip-protected` | core, access, campaigns | Build password-protected AES ZIP output and verify password-source metadata. |
+| `mail-profile-send` | core, access, campaigns, mail | Select a reusable mail profile and send through the GreenMail test bed. |
+| `legacy-inline-mail-rejected` | core, access, campaigns, mail | Confirm legacy campaign-local SMTP/IMAP data fails closed and requires explicit profile migration. |
+| `warnings-review` | core, access, campaigns | Require explicit review before queueing jobs with warnings. |
+| `blocked-send` | core, access, campaigns | Confirm blocked recipients or missing attachments cannot be queued. |
+| `mock-delivery` | core, access, campaigns, mail with dev capability | Capture messages in the development mailbox. |
+| [`greenmail-delivery`](greenmail-delivery/campaign.json) | core, access, audit, campaigns, mail | Run a credential-free Campaign through a Mail-owned profile, GreenMail SMTP/IMAP, report/audit checks, repeat-send protection, and bounded failure drills. |
+
+## Fixture Rules
+
+- Do not commit real recipients, mail credentials, or production attachment
+  names.
+- Keep attachments deterministic and small.
+- Store transport secrets only in encrypted Mail profiles or local `.env`
+  values consumed directly by the test bed, never in campaign JSON.
+- Declare optional module requirements in fixture metadata.
+- Fixtures must not import files or mail modules directly; optional behavior is
+  discovered through core module metadata and capabilities.
+
+## Validation Flow
+
+Before a release tag:
+
+1. Run module permutation startup checks from core.
+2. Run `python -m unittest discover -s tests -p 'test_example_campaigns.py'`
+   from this repository. The acceptance test copies each maintained fixture to
+   an unrelated temporary workspace before using Campaign's public loader,
+   validator, and message builder.
+3. Validate every committed example fixture against the current campaign schema.
+4. Build exact messages for each fixture.
+5. Run the mock-delivery example when the dev mailbox capability is enabled.
+6. Run `dev/mail-testbed/run_transport_smoke.py` for low-level transport and attachment variants.
+7. Run `dev/mail-testbed/run_campaign_acceptance.py` for the Campaign journey and bounded evidence.
+8. Execute the delivery checklist in
+   `docs/EXAMPLE_CAMPAIGNS_AND_RELEASE_CHECKLIST.md`.
