+## 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.

+# 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
+
+## Planned Slices
+
+1. Recipient rows and imported recipient-source snapshots
+2. Attachment bindings and frozen attachment resolutions
+3. Validation issues, review decisions, and attachment-policy overrides
+4. Delivery attempts, IMAP append attempts, Postbox attempts, and
+   reconciliation decisions
+5. Campaign shares and ownership-transfer records
+6. Import mapping profiles and import executions
+7. Reusable Campaign templates and template revisions when the template
+   library becomes persistent
+8. Export packages and protocol/report artifacts
+
+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.

+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

+systemd, container, Kubernetes, or other production supervisor and the target
