# Auditor-grade evidence and scoped reporting assurance: synthetic exercise worksheet

Curriculum reviewed: 2026-10-25. Use public or synthetic data only.
Do not include client evidence, credentials, private identifiers or raw receipts.

## Goal
deliver a synthetic assurance memorandum and refuse an expired or mutated package; “auditor-grade” describes the teaching ambition, not compliance certification or a statutory audit service.

## Outcomes
- Assemble a traceable scope-bound evidence package.
- Distinguish machine verdicts from human acceptance.
- Review grain/oracle/render evidence independently.
- Explain certification expiry and renewal without implying regulatory assurance.

## Synthetic case
Describe a Sales report built from order headers and order lines. State which grain you intend and which independently established expectation you would compare.

## Review each lesson
### 1. Define the engagement claim
State the exact report, scope, period and exclusions before inspecting evidence.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 2. Trace custody and bindings
Recheck original envelope bytes, signatures, ACKs and retained local evidence commitments.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 3. Separate four human reviews
Review grain, oracle, render and local custody as distinct responsibilities.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 4. Write the qualification report
Present machine pass/fail/blocked/stale and human recorded/not-recorded independently.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 5. Understand the award boundary
Require separate policy, legal terms, issuer authority and verified award subject.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

### 6. Renew or withdraw honestly
Reassess current evidence, expiry and revocation instead of extending an old badge.
Expected output: a written explanation naming the observation, its scope and its limits.
Your notes:

## Failure case
Generated definitions exist but a required execution observation is missing. Explain why qualification cannot pass and name the next required observation. Do not fabricate a receipt or change a frozen expectation.

## Evidence table
| Claim | Expected observation | Available evidence | Missing/stale | Next owner/action |
| --- | --- | --- | --- | --- |
| | | | | |

## Limitations
This worksheet is a completion check, not live qualification, business acceptance or a professional award. Pro assessment and certification policy remain planned. Keep optional live results in customer-controlled custody.
