#3 — CollisionDetector counted a derived template's IsInherited placeholder
rows as a distinct origin from the parent members the inheritance walk
re-adds, reporting a spurious "Naming collision" for every inherited row and
blocking any attribute/composition add to a derived template. CollectDirectMembers
now skips IsInherited rows on the direct-template and inherited-parent walks;
it keeps them for the composed-module walk, where placeholders are the sole
representation of a derived module's inherited members (that walk does not
climb the composed template's parent chain).
#7 — SandboxAttributeAccessor (Central UI Test-Run host) omitted
WriteBatchAndWaitAsync / WaitAsync / WaitForAsync, so the editor false-flagged
valid instance scripts with CS1061 even though `template validate` and the
deploy gate accept them. Added the five overloads mirroring the runtime
AttributeAccessor; they throw a labelled ScriptSandboxException if run in
Test Run (the central sandbox has no device-batch / event-waiter transport).
Tests: +3 CollisionDetector unit + 1 end-to-end TemplateService (derived add
now succeeds); +2 ScriptAnalysisService diagnose-clean. Each new test verified
to fail without its fix with the exact user-facing symptom. Full suites green
(TemplateEngine.Tests 438, CentralUI.Tests 866).
Docs: Component-TemplateEngine.md (inherited-placeholder collision rule),
Component-ScriptAnalysis.md (third sandbox surface + its compile-clean guard),
known-issues tracker #3/#7 marked resolved and the minor note promoted to #8.
Resolves InboundAPI-026/027/028/029 (+ newly-surfaced -030).
- 026: authorize the scoped Database helper in the design doc; SQL-injection
protection is parameter binding (values never concatenated); allow writes via
ExecuteAsync; drop the false 'read-only' claim. Named connections only.
- 027: async ADO.NET end-to-end (no .GetAwaiter().GetResult()); honour the method
deadline token on ExecuteScalarAsync/ExecuteReaderAsync/ExecuteNonQueryAsync +
a CommandTimeout backstop derived from the method timeout.
- 028: negative-path tests (null-gateway, deadline cancellation, parameterization)
+ e2e Database + WaitForAttribute cases through the real endpoint.
- 029: WaitForAttribute is bounded by its WAIT timeout (per-wait CTS + client-abort
+ explicit token), NOT the method deadline (spec §6) — a long wait may outlive the
method timeout; WithRequestAborted threads the raw client-abort token separately.
- 030: Central UI compile-surface mirrors (InboundScriptHost / SandboxInboundScriptHost)
gained the Database member (drifted since the runtime helper was added) so the
authorized async API type-checks at the design-time gate.
Add WaitForAttribute(attributeName, targetValue, timeout, cancellationToken)
to InboundScriptHost.RouteTarget and SandboxInboundScriptHost.RouteTarget,
mirroring the shipped runtime signature in RouteHelper. Eliminates the false
CS error the editor raised against valid Route.To("X").WaitForAttribute(...)
calls in inbound API method scripts. Test asserts the call diagnoses clean
under ScriptKind.InboundApi.
