# Contact form to actual mailbox: an end to end evidence chain

**Lead:** R03 until application/provider handoff is established, then R17 for downstream delivery. **Consulted roles:** R03, R04, R05, R07, R16, R17, R20, R21, R25, R26. **Mode:** read only diagnosis until actual authorization.

## Entry condition

A user sees form success but there is no confirmed inquiry. Use synthetic data and an authorized controlled recipient; this playbook grants no permission to email real customers.

## Sequence and ownership

### 1\. Define success states

Agree which states the system can observe: request received, validated, durably accepted, provider accepted, mailbox observed and business qualified. Do not promise later states from earlier evidence.

### 2\. Trace the application

R04 records the UI/request; R03 validates server handling, persistence, retries, queue and provider outcomes using one correlation ID. Exercise failure cases in a safe environment.

### 3\. Trace delivery

R17 uses the same message/provider ID to inspect bounce/queue and actual authorized mailbox evidence. Review SPF/DKIM/DMARC alignment and legitimate sending streams before proposing a DNS change through R02.

### 4\. Check cross cutting behavior

R05 tests required actual browsers; R07 tests keyboard, labels and error recovery; R16 compares emitted events with real states. R20 checks sensitive data handling and abuse controls.

### 5\. Verify the repair

R21 retains negative and duplicate request cases. R25 sequences the approved change. R26 reexecutes the inquiry with fresh data and reports actual mailbox observation or BLOCKED.

## Evidence package

Preserve task/run IDs, exact environment/build, timestamped observations, safe synthetic inputs, expected versus observed state, tool/browser versions, raw private artifacts and separately hashed public safe redactions. Record unavailable tools and tests not executed. Attach the handoffs rather than compressing distinct observations into one success flag.

## Acceptance

* User messages match observed application states
* The scoped synthetic inquiry is durably handled as contracted
* Required mailbox receipt is directly observed
* Analytics does not count failed/duplicate submissions as qualified inquiries

## Stop or block

Provider acceptance without mailbox access supports only provider acceptance. Do not falsify a receipt record, publish customer messages, or enforce a mail policy that has not been reviewed against legitimate senders.
