+# PromptKit request validation review remediation
+
+Status: two open findings; review complete. No production-code correction or
+architectural redesign was identified as necessary.
+
+## Review scope and evidence
+
+Reviewed implementation commits after planning baseline `3218222`, through
+`420483b2d4659862626422b0577e39bc0a4c1a2d`, against the
+[accepted feature roadmap](promptkit-validation.md),
+[implementation plan](implementation.md), applicable ADRs, and repository policy.
+The review covered production changes, new tests, the maintained consumer,
+dependency metadata/attribution, and updated documentation.
+
+The targeted architecture is present:
+
+- Core retains generic dispatch, binding, registration, and outcome ownership.
+- ckconfig retains configuration adaptation without depending on PromptKit.
+- ckprompt owns the independent validation capability, request envelope,
+  suite-returning adapter, standard command, and YAML confirmation.
+- The bundled adapter builds before loading, forwards the resulting native
+  request without merging or independent identity checks, and delegates to
+  `Engine.ValidateRequest`. Nil-builder forwarding and retained wiring issues
+  are implemented.
+- Applications retain typed input/state, defaults, artifact mapping, and runtime
+  ownership. Requirements discovery remains separate and permits partial results.
+
+Review verification passed:
+
+- Fresh `GOTOOLCHAIN=local go test -count=1 ./...` runs from each of the three
+  module directories, including the maintained composed consumer.
+- Fresh isolated `GOWORK=off`, `GOTOOLCHAIN=local`, `-mod=readonly` suite runs for
+  all three modules. Temporary manifests replaced only unpublished CommandKit
+  prerequisites; their module/sum hashes stayed unchanged during verification.
+- Isolated module and test-import listings confirm the core/ckconfig boundaries;
+  ckprompt selects released PromptKit v0.15.0 without a PromptKit replacement.
+- Changed prose whitespace and local documentation links/anchors were checked.
+
+The findings below concern test constraints that would make otherwise valid
+refactoring fail. They do not indicate an incorrect runtime result. Address them
+without changing production behavior or expanding public contracts.
+
+## R-1: Remove the required factory call after missing-selector failure
+
+Status: open. Severity: low. Category: unintended lifecycle guarantee in a test.
+
+**Location:**
+[validation_command_test.go](../../integrations/ckprompt/validation_command_test.go),
+`TestValidationCommandUsageAndInputFailuresStopProviderWork`, lines 276–283.
+
+**Finding:** The missing-required-selector case sets `wantInputCalls = 1` and
+requires that exact factory count. The comment explains the current private
+`prepareSuiteInput` order, rather than an accepted requirement. A refactor that
+detects the missing selector before allocating application input would return
+the same usage failure and correctly skip later work, but this test would fail.
+
+[ADR 0011](../adr/0011-captured-declarations-and-installation.md#input-and-shared-state-lifetimes)
+allows failures to stop later input factories. Suite GoDoc likewise says
+factories need not run after failure. The selected contract requires the usage
+classification and stopping input checks, state creation, and provider work; it
+does not require an input factory to run for this failed invocation.
+
+**Required work:** Remove the exact input-factory count assertion for this case
+and the comment that treats the private ordering as a required lifecycle. Retain
+the appropriate usage status and assertions that `CheckInput`, `NewState`, and
+the provider remain uninvoked. Preserve zero-factory assertions for malformed
+syntax and unsupported-format preflight cases where that behavior is selected.
+Keep successful-invocation and help/version lifecycle coverage.
+
+**Completion evidence:** The focused test and ckprompt suite pass; the
+missing-selector case accepts early failure before application input allocation
+without losing its guards against later work. No production change is required.
+
+## R-2: Replace the complete provider-failure stderr snapshot
+
+Status: open. Severity: low. Category: unnecessary presentation constraint in a test.
+
+**Location:**
+[validation_command_test.go](../../integrations/ckprompt/validation_command_test.go),
+`TestValidationCommandRetainsProviderDiagnosticsAndClassifiesFailures`, line 394.
+
+**Finding:** The provider-failure case requires the entire diagnostic stream to
+equal `"validation warning\nvalidation provider failed\n"`. This freezes the
+unadorned error presentation and exact line layout. An otherwise valid shared
+diagnostic formatting change, such as adding an error label, would fail this
+validation-command test even while preserving cause identity, classification,
+warning delivery, and single presentation.
+
+[ADR 0005](../adr/0005-invocation-outcomes.md) selects diagnostic ownership,
+failure classification, supported error identity, and delivery handling. It
+does not select this complete text snapshot. The
+[testing policy](../policy/testing.md#go-specific-guidance) calls for minimal
+semantic error fragments unless exact wording is contractual.
+
+**Required work:** Replace the complete failed-stderr equality with focused
+checks that the synthetic warning and provider error are delivered once.
+Retain operational classification/status, `errors.Is` cause identity, retained
+diagnostics, and applicable delivery-state checks. Controlled diagnostic-writer
+payload checks can remain; this finding does not require removing exact checks
+of bytes explicitly supplied by the test's own writer.
+
+**Completion evidence:** The focused test and ckprompt suite pass and still
+detect lost or duplicate diagnostics without fixing incidental error decoration
+or line layout. Preserve current production delivery behavior and order.
