Complete P05 under USER-WP-0030-T03. P06 remains separate. Do not send production
messages for acceptance; use the existing loopback SMTP/IMAP harness. Live SMTP
authentication diagnostics do not submit a message or claim inbox delivery.

## Expose checked service state with clear recovery steps

```task
id: USER-WP-0032-T01
status: progress
priority: high
```

Operator-only, bounded checks for KeyCape dependencies/current factor-read
credential and mail database/SMTP authentication. Show checked time, impact,
unknown versus unavailable state, retry and assisted setup; no secrets or raw
provider errors. Health probes must not send mail.

## Make selected delivery and retry safe and reviewable

```task
id: USER-WP-0032-T02
status: progress
priority: high
```

Fix failed worker claims; serialize event operations across connections; confirm
one selected delivery and reject stale/repeated completion. Missing email lane
must not mark invitations accepted. Preserve provider idempotency across lost
responses and restart; uncertain SMTP outcomes must not auto-resend. No automatic
processing of the production backlog during this task.

## Verify failure and recovery through native and harness acceptance

```task
id: USER-WP-0032-T03
status: todo
priority: high
```

Installed-provider genuine JWT expiry, scope withdrawal/recovery and outage;
native renewal/projection; SMTP/IMAP received-message and retry tests with a
local mailbox; role/CSRF/stale/ambiguous-outcome browser coverage. Publish digest
pinned releases and verify live non-sending status. Close RPF-WP-0040 acceptance
using its specified isolated fixture rather than disrupting live authentication.
