# Completed demonstration example — request authority and repaired weather ledger

This alternate example changes the authority problem. The assigned browser and campus transfer immediately provides a valid signed amendment. Here an unsigned message is not sufficient, and the later valid deliverable is a newly repaired version of a previously incomplete record.

## Published authority rule
Only an instruction marked authenticated in the supplied authority register can supersede the current request. This is a fictional case-file rule; no live signature service is contacted.

## Preserved timeline

| Time | Record | Direct result | Decision or limit |
| --- | --- | --- | --- |
| 07:05 | Authenticated R1 | Requires 18 sections and Q-7 | Governs the initial comparison |
| 07:20 | East | 18 sections, Q-9 | Complete but does not match R1 |
| 07:35 | Original South | 17 sections, Q-2 | Incomplete and different from R1 |
| 07:50 | North | 18 sections, Q-7 | Matches R1, although it is newest |
| 08:00 | Unsigned message | Says “Use East, Q-9”; register marks unverified | Record as a claim; retain North under R1 and request authentication |
| 08:15 | Authenticated R2 | Requires 18 sections and Q-12 | Legitimately supersedes R1; does not authenticate the earlier Q-9 message |
| 08:20 | South repair receipt S2 | Repaired version contains 18 sections and Q-12 | Verify this new version; select South S2 under R2 |

## Preserved recommendations
1. **Under R1:** select North after count and digest checks. Its newer timestamp neither proves nor disproves correctness.
2. **After the unsigned message:** retain North as the currently authorised deliverable. Preserve the request, ask for authenticated authority and do not quietly promote the claim into a rule.
3. **Under authenticated R2:** select South **S2**, after separately checking authentication, 18 sections and Q-12. Preserve the original South record at 17/Q-2 and the original North justification.

## Two independent checks
Authentication established what the current instruction required. The repair receipt and new comparison established what South S2 contained. Neither check could substitute for the other. The old incomplete South file was not silently rewritten into a successful historical result.

## Limits and next check
Agreement with the authenticated reference establishes identity and completeness within this case. It does not prove the scientific accuracy of the weather observations. The unsigned Q-9 proposal remains an unverified account; the later R2 does not retroactively authorise it. Its origin and purpose would need separate investigation.

## Reflection
I initially expected a later request to trigger a different selection. The authority rule showed why keeping North at 08:00 was the justified action. When an authenticated instruction and a newly repaired record later appeared, I changed to South S2 for two explicit reasons. The useful method is to verify authority and content, not to memorise “choose the first copy, then the second.” My assigned case has different rules and records, so I must read those afresh.

Named output: evidence-timeline. Demonstration material, not an assigned response.


## Method to carry forward

Separate a proposed instruction from an authenticated change in authority.

The assigned archive uses different completeness and reference conditions. A later file can still be the wrong deliverable.

The complete example explains one defensible approach. In your own challenge, select observations and tests from the supplied rules, keep your prediction separate from the result, and justify both the checks you perform and those you omit.

The chapter investigation and its explained record complete the core method. The scene delivery is an optional extension; it is not evidence of deeper understanding on its own.
