SYSE.52:4.2 - Choose what remains exact, summarized, reachable or absent
For each action-changing contribution, choose its representation:
| Representation | Useful condition | Required loss check |
|---|---|---|
| Verbatim passage or exact field | A number, condition, instruction, interface binding or unresolved effect must survive precisely. | The selected scope retains its governing qualification and origin. |
| Qualified summary | Several details can be reduced without changing the next decision. | Compare the summary with the source at each consequence it supports; keep uncertainty and defeating exceptions. |
| Recoverable pointer | The next step can obtain the original within its access and budget when needed. | Exercise that return; a missing permission or unreachable source defeats the pointer’s promised use. |
| Omission | The material cannot change this continuation or is superseded by an identified applicable contribution. | Try the meaningful contrary condition that could make it needed; preserve a trigger to rebuild. |
For a person, preserve physically readable spatial relations, labels, writable space and access to the selected writing or calculation means. A carry without its column can lose its meaning even when its digit remains legible. For a model, select within the actual context limit, including room for the requested output and tool protocol. Prefer one authoritative applicable return to several similar echoes. If indispensable content does not fit, split the requested contribution, obtain a qualified intermediate result or change the supported arrangement. Do not silently discard a required condition.
Keep the fuller available account intact for the uses it promises. Selecting less material for one step does not justify deleting the source explanation or Method. If the user must invent a missing operation, a fluent continuation has not demonstrated that the selected content supplied it.
