# Implementation Report: Spec 438 - Exchange Internal Render Model Slice 1

**Outcome**: DEFERRED — NOT IMPLEMENTED

## A. Final Gate Result

- **Outcome**: DEFERRED.

## B. Candidate Decision

- **Result**: FAIL
- **Class**: Defer
- **Score**: 5 of 12

## C. Implementation Permission

- **No** (implementation is not permitted while deferred).

## D. Reason

- No current operator workflow or direct runtime consumer exists for this slice.
- The planned internal render model would be speculative foundation without a reachable runtime owner.

## E. Runtime Work

- **None**.

## F. Files Changed

- `specs/438-exchange-internal-render-model-slice-1/spec.md`
- `specs/438-exchange-internal-render-model-slice-1/plan.md`
- `specs/438-exchange-internal-render-model-slice-1/tasks.md`
- `specs/438-exchange-internal-render-model-slice-1/checklists/requirements.md`
- `specs/438-exchange-internal-render-model-slice-1/implementation-report.md`

No `apps/platform` runtime code, test, migration, route, UI, job, command, schedule, or listener files were changed.

## G. Tests

- Not run for this deferred close-out.
- Candidate decision to defer prohibits runtime/test implementation and execution in this spec.

## H. Browser

- N/A — no rendered UI surface changed.

## I. Deployment

- None.

## J. Merge Readiness

- **Not merge-ready as an implementation**.
- Eligible only for governance/documentation close-out according to repo convention.

## K. Reactivation

- Requires a consumer-owning workflow and renewed Candidate Selection and Spec Readiness before execution.

## Branch and dirty state

- **Branch**: `feat/438-exchange-internal-render-model-slice-1`
- **HEAD at review**: `ff1a545c`
- **git status --short (at review start and end)**: `?? specs/438-exchange-internal-render-model-slice-1/`
- **Candidate state at review**: deferred-only governance updates.

## Closure proof

- **Runtime merge readiness**: FAIL
- **Implementation merge readiness**: FAIL
- **Governance close-out readiness**: PASS, only if no runtime/specs outside this deferred package are changed.

### No-runtime implementation proof

No runtime implementation was added under `apps/platform/`:

- `ExchangePowerShellInternalRenderModelBuilder` does not exist.
- `Spec438ExchangeInternalRenderModelBuilderTest` does not exist.
- `Spec438ExchangeInternalRenderModelBuilderFeatureTest` does not exist.
- `git diff --check` output: PASS.

`git diff -- specs/438-exchange-internal-render-model-slice-1` was used to confirm only spec artifacts were updated.

**Spec 438 remains deferred and must not be implemented until a current consumer-owning workflow passes Candidate Selection and Spec Readiness.**
