Website: https://contractspec.io

**Fake/sandbox outbox adapter for builder delivery loop testing.**

## What It Provides

- Simulated outbox adapter for testing builder delivery loop transitions without real provider SDKs or credentials.
- Supports `fake` and `sandbox` modes only; rejects production mode.
- Implements preflight checks, draft preparation, submission, receipt generation, and rollback.
- Idempotency key tracking and duplicate detection.
- Configurable latency simulation and failure rates for testing.

## When to Use

- Testing builder-delivery-loop transitions in development/staging.
- CI/CD integration tests that don't require real provider sends.
- Local development where real credentials aren't available.
- **Never use in production** - this adapter is explicitly designed to reject production mode.

## Usage

```typescript
import { createFakeOutboxAdapter } from '@lssm-tech/integration.fake-outbox-adapter';

const adapter = createFakeOutboxAdapter({
  mode: 'sandbox',
  simulateLatencyMs: 100,
  failureRate: 0.1, // 10% simulated failure rate
});

// Preflight check
const preflight = await adapter.preflight({
  loopId: 'loop-123',
  idempotencyKey: 'unique-key-123',
  billingOSRefs: ['billing-ref-1'],
  companyOSRefs: ['company-ref-1'],
  operatorApprovalRef: 'approval-123',
});

if (preflight.canProceed) {
  // Prepare draft
  const draft = await adapter.prepareDraft(input, preflight);
  
  // Submit
  const submission = await adapter.submit(draft, {
    draftId: draft.draftId,
    loopId: 'loop-123',
    idempotencyKey: 'unique-key-123',
    approvalStillValid: true,
    revisionAtSubmission: 1,
  });
  
  // Get receipt
  const receipt = await adapter.getReceipt({
    submissionId: submission.submissionId,
    idempotencyKey: 'unique-key-123',
  });
}
```


## Architecture

- Pure TypeScript implementation with no external provider dependencies.
- In-memory storage for drafts, submissions, and receipts.
- Fails closed on production mode detection.
- Supports idempotency for safe retry semantics.

## Safety

- **Always rejects production mode** - set `rejectProductionMode: true` (default).
- Requires idempotency keys for all operations.
- Requires operator approval references.
- Duplicate idempotency keys return existing receipts (idempotent).

## Local Commands

- `bun run dev` — contractspec-bun-build dev
- `bun run build` — contractspec-bun-build build
- `bun run test` — bun test
- `bun run lint:check` — biome check .
