Download the PHP package polysource/audit without Composer

polysource/audit

GDPR Art. 30 / HIPAA audit trail for Polysource admin actions.

Part of the Polysource monorepo. MIT-licensed.

When to use

You're running a regulated workload (healthcare, finance, B2B SaaS) and need a write-only, queryable log of every admin action: who did what, when, from where, with what outcome.

What it ships

• AuditEntry VO + AuditOutcome enum + AuditActorInterface (SymfonySecurityAuditActor default impl).
• AuditLoggerInterface (write-only) with fan-out via AggregateAuditLogger.
• DoctrineAuditLogger + Doctrine entity (polysource_audit_log table with 3 indexes for Art. 30 queries).
• ActionAuditSubscriber — bridges ActionAboutToExecuteEvent / ActionExecutedEvent (dispatched by polysource/symfony-bundle) to the logger. UUID v7 per entry, IP/UA/RequestID in context, trace truncated to 8KB.
• EasyAdminAuditSubscriber — optional bridge that audits EA CRUD edits (Edit / New / Delete on Doctrine entities). Auto-wired when easycorp/easyadmin-bundle is installed (gated on class_exists); inert otherwise.
• AuditLogResource — browsable admin resource with 5 standard filters (time range, actor, outcome, action name, resource).
• ExportAuditCsvAction — GDPR Art. 30 export with 12 locked columns (RFC 4180), gated on POLYSOURCE_AUDIT_EXPORT.
• polysource:audit:purge --before — retention command with cutoff exclusive, --dry-run, exit codes.

See ADR-020.

Install

polysource/audit declares doctrine/orm and doctrine/dbal as hard runtime dependencies. The bundled persistence layer (DoctrineAuditLogger, AuditEntryRecord, AuditLogDataSource, PurgeAuditCommand, ExportAuditCsvAction) imports Doctrine at compile time, so installing this package without Doctrine would fatal at autoload. If your host already runs Doctrine for any other reason — most Symfony apps do — the cost is zero. If you need the contracts without Doctrine, depend on polysource/core directly and ship a custom AuditLoggerInterface implementation; only the storage layer is Doctrine-coupled.

Register the bundle:

Extend it

AuditLoggerInterface is 1 method (log(AuditEntry $entry)). To pipe events to Splunk, Datadog, OpenSearch, or any SIEM:

The AggregateAuditLogger fan-outs across every tagged logger with try/catch isolation — Splunk timing out doesn't break the Doctrine write. See extensibility map.
