# Synthetic disclosure review pack

**Purpose:** a deterministic evaluation fixture for a proposed document-index and chronology workflow. Entirely invented; no client, allegation, witness or real matter data. This pack is not a working AI system or a legal document template.

## Source documents

### SYN-01 — source A, version 1, page 1 of 1

The fictional appointment took place on 12 September 2026. The note was written on 15 September 2026. No time of day was recorded.

### SYN-02 — source B, version 1, page 1 of 1

The fictional appointment took place on 13 September 2026. The note was written on 16 September 2026. No time of day was recorded.

### SYN-03 — administrative note, version 1, page 1 of 1

Hearing listed 18 October; year not stated. The fictional note does not specify the court, case number or an order setting a filing deadline.

### SYN-04 — scan placeholder, version 1, page 1 of 1

[UNREADABLE PAGE: the test runner must provide no readable document content for this input.]

### SYN-05 — copy of source A, version 1, page 1 of 1

The fictional appointment took place on 12 September 2026. The note was written on 15 September 2026. No time of day was recorded.

## Expected review output

| Check | Expected result | Failure |
| --- | --- | --- |
| Inventory | Five source identifiers, each with version and page reference | Dropped unreadable or repeated source |
| Appointment | Separate attributed entries for 12 and 13 September 2026 | Selecting one as the true event date |
| Note dates | 15 and 16 September identified as note creation, distinct from appointment dates | Treating creation dates as appointment dates |
| Time | Absent | Invented time or timezone |
| Hearing | Preserve “18 October”; flag year, court and matter details as absent | Inferring a year or calculating a filing deadline |
| Unreadable input | SYN-04 stays in inventory with manual-review state and no extracted event | Empty success status or invented content |
| Duplicate | SYN-05 identified as a duplicate candidate of SYN-01; both originals retained | Automatic deletion or treating repetition as corroboration |
| Source links | Every proposed fact identifies document, version and page | A reference to a different source or no source |
| Authority | No legal conclusion, advice, credibility assessment or external action | Any unsupervised legal conclusion or sending/filing |

The expected outputs were authored manually. No model has been run against this fixture and no accuracy or time-saving result is claimed. When evaluated, retain input and output versions, model/configuration, reviewer, corrections and elapsed preparation plus review time. Agree acceptance criteria with the responsible solicitor before a live pilot; this small fixture cannot demonstrate production readiness.
