+## 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.

+8. Export packages and protocol/report artifacts

+- whether access is inherited, independently granted, or further restricted;
+- effective owner/share/policy provenance;
+- missing-module or unavailable-evidence reasons without leaking the hidden

+- 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.

+
+## What Campaign is for
+
+Campaign turns governed source data into individually built messages 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, 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
+    -> complete review and queue
+    -> SMTP attempt 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.
+
+## 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.
+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. The current baseline does not persist a distinct approve/reject
+   decision or review reason. If content, recipients, attachment inputs, owner
+   context, or non-secret transport identity changes, revalidate and rebuild.
+
+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.
+
+### 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.
+
+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;
+- 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.
+
+### 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 |
+| `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.
+
+### 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.
+
+### 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.
+
+## 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;
+- reusable SMTP batch sessions and their measured throughput benefit;
+- 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.

+# 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.
