Move the per-script-execution Guid on ScriptRuntimeContext from
_auditCorrelationId to _executionId, and stamp it into the dedicated
AuditEvent.ExecutionId column on every script-side audit row:
- Sync ApiCall / DbWrite: ExecutionId set; CorrelationId reverts to
null (a sync one-shot call has no operation lifecycle).
- Cached-call script-side rows (CachedSubmit, immediate-completion
ApiCallCached + CachedResolve) and NotifySend: ExecutionId set;
CorrelationId unchanged (per-operation TrackedOperationId /
NotificationId).
Renames the threaded ctor param/field across ExternalSystemHelper,
DatabaseHelper, AuditingDbConnection and AuditingDbCommand, and threads
the id through NotifyHelper/NotifyTarget. The S&F retry-loop cached rows
(CachedCallLifecycleBridge) are out of scope here.
Per the Audit Log Actor-column spec, Actor should carry the calling script
identity on outbound rows (ApiCall, DbWrite, NotifySend) and a system identity
on central-dispatch rows (NotifyDeliver). The original emission code hard-coded
Actor=null at all four sites, so only Inbound API rows (API key name) ever
filled it. Stamp the script identity and 'system' respectively.
Audit Log #23 — M4 Bundle A (Tasks A1+A2): every script-initiated
synchronous DB call routed through Database.Connection(name) now emits
exactly one DbOutbound/DbWrite audit row.
Implementation — three thin ADO.NET decorators in
src/ScadaLink.SiteRuntime/Scripts/:
- AuditingDbConnection: wraps the gateway-returned DbConnection so
CreateDbCommand() hands the script an AuditingDbCommand. All other
ADO.NET surface forwards unchanged.
- AuditingDbCommand: intercepts ExecuteNonQuery / ExecuteScalar /
ExecuteReader (sync + async). On terminal:
Channel = DbOutbound, Kind = DbWrite, Status = Delivered|Failed,
Extra = {"op":"write","rowsAffected":N} (Execute*),
{"op":"read","rowsReturned":N} (ExecuteReader),
RequestSummary = JSON of SQL + parameter values (default capture;
redaction in M5),
Target = "<connection>.<first 60 chars of SQL>",
DurationMs captured via Stopwatch,
Provenance from ScriptRuntimeContext (SourceSiteId,
SourceInstanceId, SourceScript).
- AuditingDbDataReader: counts rows on Read/ReadAsync and fires the
audit emission exactly once on Close/CloseAsync/Dispose.
DatabaseHelper now takes an IAuditWriter; ScriptRuntimeContext.Database
threads through _auditWriter. When the writer is null (tests / minimal
hosts) Connection() returns the raw inner DbConnection unchanged.
Best-effort emission (alog.md §7): mirrors M2 Bundle F's 3-layer
fail-safe — build, write, continuation. Audit-build, audit-write, and
audit-continuation faults are logged + swallowed; the original ADO.NET
result (or original exception) flows back to the script untouched. The
SiteAuditWriteFailures counter increments automatically through the
existing FallbackAuditWriter (Bundle G).
Tests — tests/ScadaLink.SiteRuntime.Tests/Scripts/DatabaseSyncEmissionTests.cs
(7 new, all passing):
1. Execute / INSERT success — one DbWrite row, op=write, rowsAffected=1.
2. ExecuteScalar success — one DbWrite row, op=write.
3. Execute throws — Status=Failed, ErrorMessage + ErrorDetail set.
4. ExecuteReader success — op=read, rowsReturned counts rows pulled.
5. AuditWriter throws — original ADO.NET rowsAffected returned, no
events captured, no exception propagates.
6. Provenance populated from context.
7. DurationMs recorded non-zero.
Tests use Microsoft.Data.Sqlite in-memory (already transitively
available via SiteRuntime). Total SiteRuntime test suite: 251 passing
(244 baseline + 7 new). Full solution test suite passes.
