Bundle B1 of Audit Log #23 M3: introduces the SiteCall entity + EF mapping
for the central SiteCalls operational-state table. One row per
TrackedOperationId, mirrored from sites via best-effort telemetry then
periodic reconciliation; eventually-consistent mirror, not a dispatcher.
- src/ScadaLink.Commons/Entities/Audit/SiteCall.cs: append-once record
with required TrackedOperationId/Channel/Target/SourceSite/Status,
monotonic status update at the repo layer.
- src/ScadaLink.ConfigurationDatabase/Configurations/SiteCallEntityTypeConfiguration.cs:
table SiteCalls, PK on TrackedOperationId (stored as varchar(36) via
value conversion through the canonical 'D'-format GUID string —
matches the wire shape used by gRPC + SQLite columns), two named
indexes (IX_SiteCalls_Source_Created, IX_SiteCalls_Status_Updated).
- ScadaLinkDbContext: DbSet<SiteCall> SiteCalls in the existing Audit
section, after AuditLogs.
- Tests in tests/ScadaLink.ConfigurationDatabase.Tests/Configurations/:
table name, PK, value-conversion shape, index presence + ordering.
Bundle C migration aligns AuditLog to ps_AuditLog_Month(OccurredAtUtc).
A partitioned table's clustered key must include the partition column, so
the PK becomes the composite {EventId, OccurredAtUtc} — a divergence from
Bundle B's single-column PK that needs reconciling in the EF mapping
before the migration is generated.
EventId remains the idempotency key for AuditLogRepository.InsertIfNotExistsAsync
(M1-T8), so a dedicated unique index UX_AuditLog_EventId preserves the
single-column uniqueness constraint.
Tests updated:
- Configure_MapsToAuditLogTable_WithCompositePrimaryKey (replaces the
WithEventIdAsPrimaryKey assertion) verifies {EventId, OccurredAtUtc}.
- Configure_DeclaresUniqueIndex_OnEventIdAlone_ForIdempotencyLookups
asserts the new UX_AuditLog_EventId is unique and on EventId alone.
- Configure_ExpectedIndexes_WithCorrectNames now expects six index names
(the original five plus UX_AuditLog_EventId).
