Decisions

Numbered, append-only, cited from source by number. A decision here is a choice that constrained something afterwards - not a summary of what the code does, which the code already says.

The same discipline as the sibling projects: if a citation in a comment points at a number, this file explains it, and a number that duplicates another makes every citation of it ambiguous.

D016-D024 carry no date. Dating stopped after D015 (2026-08-26); those entries were made on or after that day and nothing narrower is recoverable. Entries after them carry one.
