Import the stable API from the package root:

from il_audit import emit, AuditContext, flush_audit_writer

Configuration

All defaults live in bundled JSON — never hardcode prices or dataset names in application code.

File	Purpose
il_audit/config/fallbacks/audit_defaults.json	Dataset, flush tuning, default cost_rates_source
il_audit/config/fallbacks/cost_rates_seed.json	Interim pricing catalog (until BQ cost_rates is scraped)
il_audit/config/cost_catalog.py	Stable service/operation/resource identifier constants
il_audit/config/audit_settings.py	Runtime settings (get_audit_settings)
il_audit/config/stores/audit_schema_store.py	BigQuery table ids and schema builders

Variable	Default (from JSON)	Purpose
IL_ENABLE_AUDIT_LOGS	true	Master switch (also respects IL_ENABLE_BQ_LOGS)
IL_BQ_AUDIT_DATASET	intelligence_layer_logs	BQ dataset
IL_BQ_LOGS_PROJECT	—	GCP project (GOOGLE_CLOUD_PROJECT / GCP_PROJECT fallback)
IL_COST_RATES_SOURCE	seed	seed or bigquery (authoritative catalog from cost_rates table)
IL_COST_RATES_CACHE_SECONDS	3600	In-memory rate cache TTL
IL_AUDIT_WRITE_QUEUE_MAX_SIZE	10000	Max pending rows before drop
IL_AUDIT_STORE_QUERY_TEXT	true	Store full chat questions in BQ (phase 2)

When IL_COST_RATES_SOURCE=bigquery, rates load from {project}.{dataset}.cost_rates. A scheduled-tasks job will scrape GCP pricing docs and maintain that table. Until then, seed JSON is used and rows are tagged pricing_source=seed_catalog.

Usage

from il_audit import AuditContext, emit
from il_audit import taxonomy as T

emit(
    T.AUTH_LOGIN_SUCCEEDED,
    context=AuditContext(app="ingest", actor_uid=uid, actor_email=email),
    status="succeeded",
    action="login",
)

Browser beacons

Mount the FastAPI router with host auth (ingest example):

from il_audit.beacon_router import create_beacon_router

app.include_router(
    create_beacon_router(
        app_name="ingest",
        get_context=audit_context_from_request,
        require_auth=require_beacon_auth,
    ),
)

Only UI_* event types from taxonomy.BEACON_EVENT_TYPES are accepted.

Chat adoption (phase 2)

1. Add same il-audit dep to chat
2. Mount create_beacon_router(app_name="chat", get_context=...)
3. Emit chat_turns on POST /query with client conversation_session_id
4. See documentation/chat-phase2.md
