# Fathom Reference Architecture

## Overview

Define meeting ingestion, consent, Fathom processing, CRM/follow-up integration, redacted observability, retention, and incident boundaries as an owned system.

## Prerequisites

- A documented data/consent model, environment boundaries, integration owners, and approved data-retention policy.

## Instructions

1. Map meeting sources, identities, processing, integrations, access, and audit paths to owners.
2. Separate development/staging/production credentials and use role-limited access at every boundary.
3. Build idempotent integrations and fallback/rollback decisions before production automation.

## Output

- An architecture record with trust boundaries, ownership, consent/data controls, and reversible integration points.

## Error Handling

| Condition | Safe response |
|---|---|
| CRM or follow-up integration fails | Pause the affected automation and use the documented reconciliation path. |
| Access boundary is unclear | Use the restrictive setting and escalate to the data/tenant owner. |
| Meeting content is exposed | Restrict access and follow the incident procedure. |

## Examples

Model a development flow from a synthetic meeting to a scoped Fathom integration and test CRM record, retaining only opaque correlation/audit metadata. Promote the reviewed version through staging before a production canary; do not make summary output an unreviewed system of record.

## Key Design Decisions

| Decision | Choice | Rationale |
|----------|--------|-----------|
| Data delivery | Webhooks | Real-time, no polling |
| Storage | PostgreSQL | Structured meeting data |
| Processing | Cloud Function | Serverless, scales with meeting volume |
| CRM sync | Async queue | Handles CRM rate limits |
