# Four-Chain Exercise Worksheet

Copy and complete this worksheet. Finish the initial-packet fields before opening the supplementary packet. Retain the first version and record changes when revising.

## A. Read each card

Record what the material says separately from what it supports. A card may support one fact while leaving other matters unknown.

| Card | Statement in the source | Supported relationship or fact | Current status and conditions | What it does not establish |
| --- | --- | --- | --- | --- |
| E01 | To complete | To complete | To complete | To complete |
| E02 | To complete | To complete | To complete | To complete |
| E03 | To complete | To complete | To complete | To complete |
| E04 | To complete | To complete | To complete | To complete |
| E05 | To complete | To complete | To complete | To complete |
| E06 | To complete | To complete | To complete | To complete |

## B. Register the initial four-chain diagram

Write each connection as start → relationship → end, with the card ID and status. Examine a signed contract separately from completed service.

| Chain | Start | Relationship or object | End | Occurred / contractually defined / proposed / unverified | Conditions and performance status | Evidence ID |
| --- | --- | --- | --- | --- | --- | --- |
| Entities | To complete | To complete | To complete | To complete | To complete | To complete |
| Entities | To complete | To complete | To complete | To complete | To complete | To complete |
| Assets | To complete | To complete | To complete | To complete | To complete | To complete |
| Assets | To complete | To complete | To complete | To complete | To complete | To complete |

| Rights | To complete | To complete | To complete | To complete | To complete | To complete |
| Rights | To complete | To complete | To complete | To complete | To complete | To complete |

## C. Gaps and supplementary evidence

Do not write only “contract missing.” Identify the relationship to establish, the specific material needed and the judgment it would affect.

| Gap ID | Unconfirmed question | Affected connection | Material requested | Information role to approach | How to assess whether the gap is addressed |
| --- | --- | --- | --- | --- | --- |
| Q01 | To complete | To complete | To complete | To complete | To complete |
| Q02 | To complete | To complete | To complete | To complete | To complete |
| Q03 | To complete | To complete | To complete | To complete | To complete |
| Q04 | To complete | To complete | To complete | To complete | To complete |

## D. Change log after further evidence

| Original card and judgment | New card | What the new material establishes | Connection to revise | What remains unknown |
| --- | --- | --- | --- | --- |
| To complete | To complete | To complete | To complete | To complete |
| To complete | To complete | To complete | To complete | To complete |
| To complete | To complete | To complete | To complete | To complete |
| To complete | To complete | To complete | To complete | To complete |

## E. Next actions

These are learners' recommendations, not tasks already assigned or confirmed in the case. Mark actual owners and dates as pending if unknown.

| Matter to establish | Suggested role | Requested material | Completion condition | Owner and expected timing |
| --- | --- | --- | --- | --- |
| To complete | To complete | To complete | To complete | Pending confirmation |
| To complete | To complete | To complete | To complete | Pending confirmation |
| To complete | To complete | To complete | To complete | Pending confirmation |
