# Promptkit Upgrade Review Remediation

## Scope And Status

Review baseline: `e177d7c`, covering implementation commits after `5c3b0cf`.
This document records a resolved test-contract issue; it does not authorize
unrelated implementation changes. No runtime defect or missing planned feature
was identified in this review. Release preparation remains separate work.

## R1: Remove The Unrequested Context-Identity Invariant

Priority: P3 (low). Status: Complete.

Original location: `internal/adapter/http/handler_test.go:334–349`,
`TestHandlerRunTimeoutValidationAndContextMapping`, introduced in `7de2b02`.

The test's `child` field and `(ctx != parent) != tc.child` assertion required
the exact parent context object for omitted/null/zero timeouts and a distinct
object for a positive timeout. The requested contract concerns effective
deadlines and cancellation propagation, not Go interface identity. In
particular, a harmless derived context that preserves the parent's deadline,
values, and cancellation would fail the omission cases despite satisfying the
application contract.

This elevated an incidental implementation choice into a test-enforced
invariant, contrary to the [agent policy](../policy/agents.md) and
[testing policy](../policy/testing.md). The current handler's context behavior
is correct; this is a maintainability issue, not a runtime cancellation bug.

### Required Change

Remove the identity comparison and the identity-only table field. Retain
behavioral assertions that an earlier parent deadline is not extended and
parent cancellation reaches execution. For omitted/null/zero values, verify
that no deadline is introduced when the parent has none. Retain coverage of
positive deadlines and the distinction between a canceled execution context
and a provider-attempt timeout while the execution context remains live.

Use the existing runner seam and focused cases; do not introduce a context
wrapper framework, timer abstraction, new public guarantee, or production
refactor solely to change this test.

### Completion Criteria

- Tests protect effective deadline/cancellation behavior without requiring
  context object identity.
- A semantically equivalent derived context does not fail merely because it
  is a different object.
- Existing timeout validation and HTTP outcome coverage remains intact.

### Resolution And Validation

Removed the identity-only table field and context comparisons. The test now
checks effective deadlines, including omitted/null/zero requests with no
parent deadline, and explicitly checks that parent cancellation reaches the
runner. Existing positive-deadline integration tests and live-context
provider-timeout mapping remain intact. No production code changed.

Focused HTTP timeout tests, `go test ./...`, `go test -race ./...`,
`go vet ./...`, a native build outside the repository, and `git diff --check`
all passed after remediation.

## Original Review Verification

- `go test -race -count=1 ./...` passed, including retry, shared-capacity,
  deadline, report, definition-conformance, and architecture-boundary tests.
- `go vet ./...` passed.
- A native `cmd/scriptorium` build passed, with output outside the repository.
- The selected dependency is Promptkit v0.11.0 with its intended v2 catalogs.
- Application code, tests, release automation, and historical releases were
  not changed during this review.

The runtime ownership boundaries remain as intended: Promptkit owns framework
formats, execution, retries, and backend admission; Scriptorium owns executable
adapters, application settings, HTTP artifact policy, deadlines, and terminal
report presentation. No additional runtime restrictions, durable workflow
state, or extra release compliance gates were identified in the reviewed diff.
