# Observed fictional practice examples

Observed 7 October 2026 in ChatGPT web, default mode. Exact model version was not exposed. No private documents or customer data were used. This is one observed run, not a benchmark across platforms.

## Spreadsheet input

Category,Amount
Supplies,12
Travel,20
Supplies,8
Software,15
Travel,5

Request: sum B2:B6 where A2:A6 matches E2, report Supplies/Travel/Missing totals and text-number/trailing-space limitations.

## Observed spreadsheet answer

=SUMIF(A2:A6,E2,B2:B6)

Expected totals: Supplies → 20; Travel → 25; Missing → 0.

If an amount in B2:B6 is stored as text, SUMIF may ignore it rather than add it. Convert those cells to numeric values. If a category contains trailing spaces, it will not exactly match Supplies. Clean the category data with TRIM, or use a cleaned helper range/formula. These are the expected results from the supplied sample data; I have not actually run the spreadsheet.

Verification: independently calculated fixture totals are 20, 25 and 0. Google Sheets itself was not executed. Text-number and whitespace edge cases need an actual spreadsheet check.

## Document input

Version A: Launch Friday. Budget 100. Deliverable CSV export.
Version B: Launch Monday. Budget 100. Deliverable CSV export.

Request: exact-phrase comparison, unchanged requirements explicit, unresolved decisions; no invented authority, owner, reason or calendar dates.

## Observed comparison answer

| Field | Version A exact phrase | Version B exact phrase | Change |
|---|---|---|---|
| Launch | “Launch Friday.” | “Launch Monday.” | Changed: Friday → Monday |
| Budget | “Budget 100.” | “Budget 100.” | Unchanged |
| Deliverable | “Deliverable CSV export.” | “Deliverable CSV export.” | Unchanged |

Unresolved decision: Launch day — Friday vs Monday. Unchanged requirements remain explicit: Budget 100 and Deliverable CSV export.

Verification: all quoted phrases match the fictional inputs. Only the launch day changes. The answer does not select an authoritative brief. Real documents require source review.
