## Genesis PRD: Implement Exponential Backoff for Email Delivery

This PRD focuses on implementing exponential backoff for email sends that initially fail, improving the reliability and resilience of AIVA's email delivery system.

### GPM-062: Implement Basic Exponential Backoff Logic
**Goal:** Implement a basic exponential backoff retry mechanism for failed email sends.
**Acceptance Criteria:**
- When an email send fails (e.g., due to a temporary network issue), the system retries the send after a delay.
- The delay increases exponentially with each failed attempt (e.g., 1 second, 2 seconds, 4 seconds).
- A maximum number of retry attempts is configured (e.g., 3 attempts).
- After the maximum number of retries, the email is marked as failed and logged.
**Files:** `aiva/email/retry_strategy.py`, `aiva/email/email_sender.py`
**Spawns:** Implement configurable backoff parameters.

### GPM-063: Configure Backoff Parameters
**Goal:** Allow administrators to configure the exponential backoff parameters (initial delay, multiplier, max retries).
**Acceptance Criteria:**
- Backoff parameters are configurable via environment variables or a configuration file.
- The system uses the configured parameters for the exponential backoff algorithm.
- The configuration parameters are validated to ensure they are within reasonable bounds.
**Files:** `aiva/config.py`, `aiva/email/retry_strategy.py`
**Spawns:** Implement monitoring and logging of backoff retries.

### GPM-064: Log Failed Email Sends with Backoff Details
**Goal:** Log detailed information about failed email sends, including the retry attempts and backoff delays.
**Acceptance Criteria:**
- Every failed email send (after all retries) is logged, including the recipient, subject, and error message.
- The log entry includes the number of retry attempts and the total backoff time.
- Log messages are structured and easily searchable.
**Files:** `aiva/email/email_sender.py`, `aiva/logs/email_failures.log` (or appropriate logging mechanism)
**Spawns:** Implement monitoring of email delivery success rate with retries.

### GPM-065: Monitor Email Delivery Success Rate with Retries
**Goal:** Track and monitor the email delivery success rate, taking into account the emails that were successfully delivered after retries.
**Acceptance Criteria:**
- A dashboard or reporting system displays the overall email delivery success rate.
- The system tracks the number of emails successfully delivered on the first attempt vs. after retries.
- Alerts are triggered if the email delivery success rate falls below a defined threshold.
**Files:** `aiva/monitoring/email_metrics.py`, `aiva/dashboard/email_report.py`
**Spawns:** Implement circuit breaker pattern to prevent overwhelming failing email providers.

### GPM-066: Implement Testing for Retry Logic
**Goal:** Add unit and integration tests to verify the exponential backoff logic and email delivery retries.
**Acceptance Criteria:**
- Unit tests verify the correct calculation of backoff delays.
- Integration tests simulate email send failures and verify that retries occur as expected.
- Tests cover different failure scenarios (e.g., temporary network issues, rate limiting).
**Files:** `tests/unit/email/test_retry_strategy.py`, `tests/integration/email/test_email_sender.py`
**Spawns:** Implement different backoff strategies (e.g., jitter).

### GPM-067: Add Jitter to Backoff Delay
**Goal:** Improve the resilience of the email delivery system by adding jitter to the backoff delay.
**Acceptance Criteria:**
- A random jitter value is added to the calculated backoff delay.
- The jitter prevents multiple failed emails from being retried simultaneously, reducing the risk of overwhelming the email provider.
- The jitter value is configurable.
**Files:** `aiva/email/retry_strategy.py`, `aiva/config.py`
**Spawns:** Research and implement adaptive backoff based on server response codes.
