Field Log

Field Log is a small tool for capturing the reason a decision was made before the context evaporates. It is closer to a lab notebook than a wiki: dated entries, a short title, the options considered, and the pressure that shaped the choice.

Why it exists

Code keeps the decision. It rarely keeps the reason. Six months later the next change has to reconstruct the constraint from comments, pull requests, and memory.

A useful log is the one people actually update. Field Log stays close to the work, keeps entries short, and treats a date and a paragraph as enough.

The shape of an entry

• A date and a title.
• The options that were on the table.
• The reason one of them won.
• A link to the change when the implementation matters.

The audience is not a future historian. It is the next person trying to modify the system without accidentally undoing a constraint that still applies.
