The store-and-forward retry loop emits the per-attempt and terminal cached
audit rows (ApiCallCached/DbWriteCached Attempted, CachedResolve) via
CachedCallLifecycleBridge from a CachedCallAttemptContext, not from the
script context. The ExecutionId rollout (Task 4) already threaded ExecutionId
and SourceScript through this path; ParentExecutionId — the spawning
inbound-API request's ExecutionId — was not, so those retry-loop rows had
ParentExecutionId = null even for an inbound-API-routed run.
Thread it additively as a sibling at every carry point ExecutionId passes
through:
- StoreAndForwardMessage gains ParentExecutionId (Guid?).
- StoreAndForwardStorage adds a nullable parent_execution_id column via the
same idempotent PRAGMA-probed ALTER TABLE migration; rows persisted by an
older build read back null (back-compat). The defensive Guid.TryParse read
helper (ParseExecutionId) is renamed ParseGuidColumn and reused for both
columns so a corrupt value cannot abort the retry sweep.
- StoreAndForwardService.EnqueueAsync gains an optional parentExecutionId
param, stamped onto the buffered message and surfaced on the
CachedCallAttemptContext built in the retry loop.
- CachedCallAttemptContext gains ParentExecutionId.
- CachedCallLifecycleBridge.BuildPacket sets AuditEvent.ParentExecutionId
from the context, beside the existing ExecutionId.
- IExternalSystemClient.CachedCallAsync / IDatabaseGateway.CachedWriteAsync
gain an optional parentExecutionId param; ScriptRuntimeContext's CachedCall
/ CachedWrite helpers pass _parentExecutionId.
All threading is additive — ParentExecutionId is Guid? everywhere, null for
non-routed runs, and old buffered S&F rows still deserialize with the new
field null.
The store-and-forward retry loop emits the per-attempt and terminal cached
audit rows (ApiCallCached/DbWriteCached Attempted, CachedResolve) via
CachedCallLifecycleBridge from a CachedCallAttemptContext, not from the
script context. ExecutionId (and SourceScript) were not threaded through the
S&F buffer, so those rows had ExecutionId = null and SourceScript = null.
Thread both, additively, from the cached-call enqueue path:
- StoreAndForwardMessage gains ExecutionId (Guid?) / SourceScript (string?).
- StoreAndForwardStorage adds nullable execution_id / source_script columns
via an idempotent PRAGMA-probed ALTER TABLE migration; rows persisted by
an older build read back null (back-compat).
- StoreAndForwardService.EnqueueAsync gains optional executionId /
sourceScript params, stamped onto the buffered message and surfaced on the
CachedCallAttemptContext built in the retry loop.
- CachedCallAttemptContext gains ExecutionId / SourceScript.
- CachedCallLifecycleBridge.BuildPacket sets AuditEvent.ExecutionId and
AuditEvent.SourceScript from the context (replacing the hard-coded
SourceScript = null and its now-stale comment).
- IExternalSystemClient.CachedCallAsync / IDatabaseGateway.CachedWriteAsync
gain optional executionId / sourceScript params; ScriptRuntimeContext's
CachedCall / CachedWrite helpers pass _executionId / _sourceScript.
Script-side cached rows (CachedSubmit, immediate Attempted+Resolve) are
unchanged. All threading is additive — old buffered S&F rows still
deserialize and process with the new fields null.
Rework ScriptRuntimeContext.ExternalSystem.CachedCall to fit the M3
combined-telemetry model:
* Mints a fresh TrackedOperationId and emits one CachedSubmit packet
via ICachedCallTelemetryForwarder BEFORE handing the call off — the
SiteCalls row is materialised before the first delivery attempt so
Tracking.Status(id) can observe a Submitted row even if immediate
delivery resolves before the helper returns.
* Threads the TrackedOperationId into IExternalSystemClient.CachedCallAsync
as a new optional parameter (and into IDatabaseGateway.CachedWriteAsync
for the Database mirror set up here for E6). The gateway uses the id
as the StoreAndForward messageId so the retry loop (Tasks E4/E5) can
recover it from StoreAndForwardMessage.Id.
* Returns the TrackedOperationId rather than ExternalCallResult — the
script's contract is now "get a tracking handle, observe outcome via
Tracking.Status". Best-effort emission: a thrown forwarder is logged
+ swallowed; the original call still runs and the id is still returned.
DatabaseHelper gets the matching siteId / sourceScript / forwarder
fields and a parallel CachedSubmit emitter (Channel=DbOutbound) so Task
E6's Database.CachedWrite mirror plugs in without further runtime
wiring.
New ICachedCallTelemetryForwarder seam in Commons.Interfaces.Services
so SiteRuntime depends on Commons (existing arrow) rather than
ScadaLink.AuditLog (would have introduced a new dependency).
Bundle E task E3 (and helper-shape work for E6).
