3tears-agent-audit

Unified audit envelope + fire-and-forget publish helper for the 3tears platform.

Purpose

Single AuditEvent envelope + single publish_audit helper used by every domain (workspace, rbac, memory, custom tools) so the audit pipeline is one subject tree, one consumer, one table, one admin query API. Replaces domain-specific envelopes (WorkspaceAuditEnvelope, RbacAuditEnvelope) that produced slightly-different wire shapes per domain and made cross-domain audit queries require a UNION.

The package is pure Python with no NATS consumer code and no Postgres code. Publish is the only direction: a consumer-side audit consumer owns persistence to the audit events table.

Public API

from threetears.agent.audit import AuditEvent, publish_audit

• AuditEvent -- pydantic BaseModel with extra='forbid', timezone-aware timestamp validator, closed event_type string family (dotted verb, e.g. workspace.fs_write, rbac.assignment.create). All common identity fields are typed columns on the envelope; event-type-specific extras live in details: dict[str, Any].
• publish_audit(event, nats_client, namespace) -- fire-and-forget async helper. Serializes the envelope via model_dump_json() and awaits one nats_client.publish on {namespace}.audit.{event_type}. On any publish failure logs at WARN and returns; never raises.

Design commitments

• Fire-and-forget. Audit publish failures must never break the producing call. The helper catches every exception, logs at WARN, and returns.
• Typed wire contract. extra='forbid' + timezone-aware validator catch publisher-side drift at construction time, not at the consumer's decode.
• No domain-specific envelope types. Every domain publishes the same model; event_type conveys the domain.
• No dual-emit. There is no legacy envelope the consumer still accepts in parallel. Emission sites migrate in the same PR that deletes the legacy envelope module.

Subject naming

{namespace}.audit.{event_type} where event_type is the dotted event name (e.g. {namespace}.audit.workspace.fs_write). The consumer subscribes to {namespace}.audit.> so new event types route automatically without consumer-side changes.
