+## 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.

+replacement worker after Redis visibility recovery. Passing evidence also
+requires durable `outcome_unknown`, an empty broker queue/unacked set, and
