To get started with DMARQ, please see the [Getting Started](user_guide/getting_started.md) guide.
For installation instructions, check the [Docker Setup](deployment/docker.md) or [Manual Installation](deployment/manual.md) guides. Operators should use the [Operator Runbook](deployment/operations.md) for deployment modes, verification, upgrades, and rollback, and the [Troubleshooting Playbooks](deployment/troubleshooting.md) for ingestion, authentication, DNS, database, and notification failures. For production secrets, use [Secret Handling with 1Password](deployment/secrets.md). For database operations, use [Database Backup and Restore](deployment/backups.md). For upgrades, use the [Release Checklist](deployment/release-checklist.md).
For aggregate-report parser support, known edge cases, and fixture guidance, see [DMARC Aggregate Format Compatibility](reference/dmarc-compatibility.md).

- Add parser compatibility for RFC 9990-style aggregate report namespaces, version detection, policy metadata, identifiers, override reasons, auth-result details, and namespaced extensions.
- Keep legacy RFC 7489-style reports backward compatible through fixture coverage.
- Persist and CSV-export newly introduced aggregate metadata with nullable, backward-safe database fields.
Planned:
- Update domain/source reporting to include new metadata where it improves operator actionability.
- Add fixture-driven tests for representative real-world DMARCbis-style reports.
- Update documentation to clarify supported formats and terminology.
- Add a fixture-driven compatibility pack covering parser, upload, IMAP, and Gmail import paths with supported-format documentation.
- Verify domain report views and CSV exports render fixture-backed DMARCbis-style imports correctly.
Exit criteria:
- A DMARCbis-style aggregate report can be imported via upload/IMAP/Gmail and renders correctly in dashboards and exports.

# DMARC Aggregate Format Compatibility
DMARQ imports DMARC aggregate reports from direct uploads, IMAP attachments, Gmail API attachments, and the Cloudflare Email Worker webhook. Compatibility is locked by the fixture pack in `backend/app/tests/fixtures/dmarc_aggregate`.
## Supported Aggregate Inputs
- Plain XML files with a `.xml` extension.
- ZIP archives containing an XML report.
- GZIP archives with `.gz` or `.gzip` extensions.
- RFC 7489-compatible aggregate reports without XML namespaces.
- Namespaced aggregate reports using `urn:ietf:params:xml:ns:dmarc-2.0`.
- RFC 9990-style reports with optional metadata such as `version`, `generator`, `extra_contact_info`, repeated `error` values, `np`, `fo`, `testing`, `discovery_method`, `envelope_to`, policy override reasons, `human_result`, SPF `scope`, and namespaced extension elements.
## Preserved Metadata
Newer optional fields are parsed without changing the legacy response shape that existing screens use. When a database is configured, DMARQ also persists the optional report metadata, policy metadata, record identifiers, policy override reasons, and extension payloads so exports and future views can use them.
CSV exports include the most useful aggregate metadata for operators:
- `subdomain_policy`
- `non_subdomain_policy`
- `adkim`
- `aspf`
- `failure_options`
- `testing`
- `discovery_method`
- `schema_version`
- `report_variant`
- `generator`
## Known Edge Cases
- Unknown namespaced extension fields are preserved as best-effort key/value data after namespace prefixes are stripped by the XML parser.
- Malformed optional timestamps and counts use safe defaults so one bad optional value does not reject the whole report.
- Reports with no `<record>` elements import with a zero-count summary.
- Unsupported attachments are skipped by IMAP and Gmail import paths and recorded in import details when stats are available.
- For duplicate detection, DMARQ uses the domain and `report_id` pair. Fixture report IDs must remain unique within a single test import run.
## Fixture Pack
The current fixture pack covers:
- `rfc7489-google.xml`: legacy no-namespace aggregate report.
- `rfc9990-namespaced-legacy-fields.xml`: namespaced aggregate report that keeps legacy fields working.
- `rfc9990-treewalk-extension.xml`: RFC 9990-style policy metadata, treewalk discovery, `envelope_to`, override reasons, auth-result details, and report/record extensions.
- `rfc9990-multi-auth-overrides.xml`: multiple records, multiple DKIM auth results, policy override reasons, PSD-style discovery, and nested vendor extensions.
The compatibility tests exercise every fixture through parser extraction, upload import, IMAP attachment import, and Gmail attachment import.
## Adding Fixtures
1. Add the XML file under `backend/app/tests/fixtures/dmarc_aggregate`.
2. Add its expected metadata to `DMARC_COMPATIBILITY_FIXTURES` in `backend/app/tests/test_data.py`.
3. Include a unique `report_id`, stable domain, expected variant, expected total count, and any policy fields that should be asserted.
4. Run `pytest backend/app/tests/test_dmarc_compatibility_fixtures.py backend/app/tests/test_dmarc_parser.py backend/app/tests/test_reports_api.py`.
